Abstract
Due to global warming temperature is increasing at a rate unmatched by any temperature change over the last 50 million years. Drought and Heat stress due to increased temperature are agricultural problems in many areas in the world. This review describes some aspects of high temperature and drought induced changes in morphological, physiological, biochemical and molecular changes in plants, which affect plant growth and development and may lead to a drastic reduction in economic yield. Flag leaf area, relative water content, proline content and grain yield decreased significantly under drought stress environment as compared to irrigated environment. The adverse effects of heat stress can be mitigated by developing crop plants with improved thermotolerance using various approaches. This study was aimed at evaluating some parameters such as stomatal conductance (gs), canopy temperature (CT), canopy temperature depression (CTD) and heat shock proteins etc.

Abstract
Phosphate solubilizing microorganisms were isolated from rhizosphere soil of various leguminous plants. Phosphate solubilizing microbial colonies was varied from each and every leguminous plant. Bacterial population was more in number when compared to fungal population. The highest phosphate solubilizing bacterial population was observed in Clitoria ternatea. Bacillus sp. and Aspergillus sp. were the dominant organisms found almost in all the rhizosphere soil samples. A clear halo zone was produced by the phosphate solubilizing microorganisms on solid Pilovskaya’s agar medium with tricalcium phosphate, indicating that phosphate solubilizing ability of the bacterial and fungal isolates. These isolates were used to prepare microbial inoculants. Different ratios of vermicompost and rice bran were used as a carrier material to prepare phosphate solubilizing microbial inoculants. The ratio of vermicompost and rice bran is in increasing order 2:1, 4:1 and 6:1 showed higher counts of viable cells in the carrier material. Phosphate solubilizing soil bacteria could serve as efficient microbial inoculants for improving the phosphorus nutrition of crop plants.

Abstract
The purpose of the study was to evaluate the effects of organic amendments on soil fertility in terms of biological properties in the process of organic production of bell pepper. Two bell pepper (Capsicum annuum L.) varieties viz California Wonder and Gangavati Local raised under nine completely organic nutrient sources along with recommended package of practice and completely inorganic nutrients sources. The initial and after cropping season soil biological properties were studied by using standard procedures in their estimation. The results revealed that after two cropping seasons, irrespective of varieties there was substantial increase in the total bacterial count (22.97%), fungi (20.23%), actinomycetes (36.89%) and mycorrhiza (44.63%) in all the nutrient combinations wherever organic sources were used compared to inorganic treatment. All the organic nutrient sources were found to be similar in their effect on soil biological properties. Among the organic sources of nutrients the soils of O5 [FYM (50%) + PM (50%) equivalent 100% RDN basal)] had most beneficial biological properties in terms of higher microbial population viz fungi, bacteria, actinomycetes, mycorrhiza and dehydrogenase activities. The least was observed in inorganic control treatment O11 (100 % RDF).

Abstract
A field experiment was conducted during kharif 2009 at Agricultural College Farm, Karekere, Hassan, Karnataka on sandy loamy soil. The experiment was laid out in a randomized complete block design with four treatments replicated thrice. The dry matter accumulation both in haulm and tuber was significantly influenced by various treatments compared to farmers practice and application of farm yard manure alone. The potato tuber yield (16.50 t ha-1) with the application fertilizers as per the farmers practice and FYM @ 25 t ha-1 alone (10.92 t ha-1) was significantly lower than that obtained with application of recommended dose of fertilizers from different sources and time of application along with FYM @ 25 t ha-1 (20.64 to 22.24 t ha-1). However, the highest tuber yield of 22.24 t ha-1 was obtained with the application of recommended dose of fertilizer through DAP, urea and SOP along with FYM @ 25 t ha-1 which was at par with the tuber yield recorded in other recommended dose of fertilizer treatments. The available nutrient status of both macro and micronutrients was increased in the soil after the harvest of the crop due to application of recommended dose of fertilizer from different fertilizer source along with FYM.

Abstract
The creation, growth and decay of any social system, retaining myriads of life forms, have basically been the concerns and exposition of energy. Social metabolism envisage a natural connectivity amongst physical, biological and social systems ad their under lying cybernetics. It is the flow of energy that drives the social systems generating information, applying information and transforming the present social process in to a desired social out come. Energy remains retained, shelved and configured within a cell and within a social capsule and also is subject to a ruptured release for unlashing motivations and psychological capabilities. The present paper examines the collision and collusion between imposed technologies vis-a-vis extraneous knowledge vs intrinsic vis-a-vis in situ knowledge. The rejection of innovation, prescribed by experts, has got a reverse osmosis impact in the entire technology socialization process. Generally the rejected and discontinued technology has been branded as laggard but the logic behind rejections not esteemed properly. The farming system performance cannot be conceived as an indoor, interactive drama, rather it is a splendid disposition of social metabolism, where in the flow in and flow out of energy can be audited and monitored for sustainable farming performance of both the farmer and the manager or the both encapsulated in a single entity. The factors like cropping intensity, size of holding, education, motivation, access to information, the socialization level of technology have been found generating reticulate impact on the social osmosis through the intervening characters like, adoption, rejection and discontinuance, on and over a spectrum of prescribed innovation.

Abstract
Influence of male sterility inducing cytoplasm on combining ability with respect to ethanol yield and its attributing traits in sweet sorghum was studied in 48 hybrids developed by crossing six A- lines viz ICSA 631, ICSA 731, ICSA 324, ICSA 500, ICSA 38 and ICSA 84 and their corresponding B- lines with four R- lines viz SEREDO, ICSV 700, ICSV 111 and E 36-1 in line × tester mating design. The 16 parents and their 48 hybrids were grown separately in contiguous blocks in single row of 3m length with 0.15 m × 0.60 m spacing in simple lattice design with two replications at the experimental plots of University of Agricultural Sciences (UAS), Gandhi Krishi Vignana Kendra (GKVK), Bangalore, and Karnataka, India. Significant cytoplasm effects on gca effects of A & B -lines and on mean performance and sca effects of hybrids were detected only in a few of the nuclear genetic backgrounds. The direction and magnitude of the effects varied with the trait and the nuclear genetic background and was minimal to have any practical significance on the performance of hybrids in respect of any of the traits. The mean cane height, mean cane weight, juice volume per plant, juice extraction per cent and ethanol yield per plant of male sterile cytoplasm based hybrids were comparable with that of the male fertile based hybrids.

Abstract
Five soil profiles were studied under different land use systems. The soils were found to be slightly acidic in soil reaction and all most all the soils were found to be low in electrical conductivity indicating low amount of soluble salts in the soils, while organic carbon content gradually decreased with depth among the land use systems. Low cation exchange capacity values were observed under different land use systems studied which may be attributed to low clay content and dominance of Kaolinite type of clay. Calcium carbonate content increased from 0.32 to 0.69% cent in all the profiles. Free iron oxides that in all the profiles are relatively low and it decreases with depth. The available nitrogen, phosphorus, potassium and sulphur were decreased usually with depth. Exchangeable calcium and magnesium increased from 5.80 to 6.80 and 2.10 to 2.90 cmol (P+) kg-1 among the land use systems. Among the land use systems micronutrient were decreased with depth it might be due to its close association with organic matter.

Abstract
An attempt to measure the variability to frost damage during winter 2011-12 among 57 mulberry germplasm accessions of five Morus spp. was made at Central Sericultural Research and Training Institute, Pampore, Kashmir, India. Frost damage was measured as the cumulative dieback of shoots from longest, shortest and median branches in three randomly selected trees from each germplasm accession during April 2012. Irrespective of the species, origin and shoot length the mean frost damage was 12.08% which ranged from 0.16 (S-146) to 33.29% (C-763). Among the Morus species, M. bombycis registered lowest dieback followed by M. multicaulis, M. indica and M. alba and highest was observed with a sole accession of M. kayayama. The mean frost damage in indigenous mulberry accessions (13.31%) was relatively more compared to that in exotic accessions (10.39%). Among the indigenous mulberry accessions, native germplasm from Kashmir registered lower frost damage (6.47%) compared to rest (15.58%). S-146 registered the highest tolerance to frost damage with a dieback of 0.16% followed by S-1708 and four Kashmir accessions viz Chattatul, Botatul, Chattatul Zangir and Zangabad. Among the exotic genotypes, Serpentina of Italian origin offered the highest tolerance followed by Goshoerami, Obawase, Enshuutakasuke and Rokokuyoso of Japanese origin. Shimanouchi and Kasuga of Japanese origin and Mandalay of Burma origin were severely damaged among the exotic group. Tallest branch in a tree registered more frost damage (14.32%) than median (11.56%) and shortest branches (8.70%), in general. Correlation studies with dieback due to frost damage and shoot length registered weak and negative relationship. This study marks a beginning in understanding the complex response of mulberry to extreme winters of Kashmir.

Abstract
Fossil energy resources, the primary source of transport fuel in the world is depleting dramatically to meet the ever-increasing energy demands globally. However, climate change caused by green house gas emissions (GHG) from fossil fuels and energy security in the future are the two major concerns which drives us to search for alternative energy sources. Crop plants are one of the best sources of renewable energy which can be used as feedstock for biofuel production. Hence, the biofuel resources like sweet sorghum, other herbaceous grasses and fast growing forest trees are on their way to meet the energy requirements. Sweet sorghum, a C4 graminaceous crop which has sugar rich stalks and which is a water use efficient crop has a very good potential as an alternative feed stock for ethanol production. Ethanol yield and its attributing traits in sweet sorghum was studied in 24 hybrids developed by crossing six A- lines viz, ICSA 631, ICSA 731, ICSA 324, ICSA 500, ICSA 38 and ICSA 84 with four R- lines viz, SEREDO, ICSV-700, ICSV 111 and E 36-1 in a line × tester mating design. The 10 parents and their 24 hybrids were grown separately in contiguous blocks in single row of 3m length with 0.15 m × 0.60 m spacing in simple lattice design with two replications at the experimental plots of Gandhi Krishi Vignana Kendra (GKVK), University of Agricultural Sciences, Bangalore. Mean performance and manifestation of significant in hybrid heterosis for mean cane height, mean cane weight, juice yield, juice extraction per cent and ethanol yield was observed.

Abstract
A pot experiment was conducted at College of Agriculture, Latur, during the year 2009, to study the quality and decomposition rate of vermicompost as influenced by crop residues and earthworm species. The crop residues, viz sugarcane, soybean, sorghum, pigeon pea, wheat, sunflower were inoculated with earthworm species Eudrilus eugeniae and Eisenia foetida and monitored for the rate of decomposition of crop residues and quality of vermicompost. Periodical observations were taken for 80 days. Among the different crop residues vermicompost prepared from soybean gave good quality vermicompost followed by pigeon pea. Vermicompost prepared from soybean is rich in N, P, K and micronutrients as compared to remaining all the crop residues, however C:N ratio of pigeon pea residues was narrower followed by soybean. The quality of vermicompost was found superior due to earthworm species Eisenia foetida (S1) because of higher nutrient concentration in vermicompost.

Abstract
A field experiment with maize (Zea mays L.) cv. Kargil M-900 Gold was conducted at Main Agricultural Research Station, Dharwad, Karnataka during kharif season of 2010 and 2011 with four planting dates viz June first fortnight, June second fortnight, July first fortnight and July second fortnight with four cropping systems namely, intercropping of maize and pigeonpea 2:1, 2:2 and 4:2 row ratio including sole maize. Various thermal indices including growing degree days (GDD), phenothermal index (PTI) and heat use efficiency (HUE) for maize were calculated by using standard methods for above treatments. The results showed that timely June I fortnight sown maize took significantly more number of days (111 days) and growing degree days (1569.1) to complete physiological maturity and recorded higher heat efficiency (0.363 g plant 1 °C day-1) as compared to subsequent delayed sowing, but was on par with June II fortnight sowing). Among the various cropping systems sole maize took more number of days and growing degree days to complete physiological maturity and registered higher heat use efficiency as compared to maize grown in association with pigeonpea irrespective of row ratio.

Abstract
Future agriculture is more concern on energy saving even small variation in pressure leads to more consumption of energy to pump for distributing water for irrigation in this scenario a research work carried in ZARS, GKVK, UAS, Bangalore on pressure variation of different micro sprinklers. Pressure discharge relationship can be very well established by the power type equation of form Q = aHb indicating that discharge increases with increase in pressure. The values of discharge exponent close to 0.5 for all the type of micro sprinkler indicated that all the three types of micro sprinklers are of desired quality in terms of their response to variation in operating head. Minimum discharge of 30.26, 50.21 and 83.63 lph were recorded for the operating pressure of 1.0 kg/cm2, where as the maximum discharge of 59.10, 86.0 and 128.10 lph were recorded for operating pressure 2.6 kg/cm2 for S-2, S-3 and S-1 micro sprinkler respectively. The S-2 type micro sprinkler has the lower discharge than other two micro sprinklers at the same operating pressures.

Abstract
An experiment was conducted to study the efficacy of some commercial feed supplements alone or in combination on the performance of broiler chickens. For the purpose, 320 day-old unsexed commercial broiler chicks were distributed sixteen replicates of 20 chicks each. Eight treatments viz Control (T1), Hepatocare (T2), Cal-c-care (T3), Nephrosol (T4), Hepatocare + Cal-c-care (T5), Hepatocare + Nephrosol (T6), Cal-c-care + Nephrosol (T7), Hepatocare + Cal-c-care + Nephrosol (T8) was assigned to duplicate groups. All the fed supplements were administered through water as per the recommendations and the trial lasted for 42 days. The cumulative body weight gain, feed consumption, feed conversion ratio, livability and net returns were ranged from 2236 (T1) to 2359 g/bird (T2), 4006 (T5) to 4168 g/bird (T1), 1.72 (T4) to 1.87 kg feed/kg weight gain (T3), 93.0 to (T2) to 100 per cent (T5) and from Rs. 20.5 (T1) to 27.0/bird (T2 and T4), respectively however, the differences are statistically similar (p >0.05) among different treatments. In general, the performance of broilers supplemented with feed supplements particularly Hepatocare was better when compared to control and found to be economical.

Abstract
Axillary buds excised from aseptic shoot cultures of mulberry were encapsulated in sodium alginate provided with MS nutrients and protectants as a synthetic endosperm to enhance survival, germination and prevent contamination of encapsulated axillary buds of mulberry. The synthetic seeds with synthetic endosperm constituents of MS nutrients, streptomycin sulphate (0.1%) and carbendazim (0.1%) gave not only good protection against contaminants, but also resulted in germination of nearly 60 per cent of the encapsulated axillary buds. Among the two different storage temperature, storage of synthetic seeds at 5°C was most preferable as more than 50 per cent of the encapsulated axillary buds survived for as long as 30 days.

Abstract
The present paper has been the outcome of a rigorous research work to identify the factors attributing to the fast reduction of local fish biodiversities. The indigenous fish goners are the most important bio-ecological indicators to measure the intensity of changes disturbing ecological balances of any micro-farming system both in intrinsic and extrinsic manner. Some local and innovative measuring devices, elicited by the stakeholders themselves, were applied to calculate the FMV and fish landing in different local markets. This would ultimately make the researchers draw conclusion that the factors like chemical loads in agriculture, occupational change of the rural people, destruction of local bodies, indiscriminate use of pesticides in agricultural field and adjoining water bodies are all responsible for ushering a faster decline of these local fish species. The decline of species has been measured in terms of loss of decadal score down the years and declining availability of these fishes across the spatial distribution had been statistically intercepted to get the most expected estimation of species count and the factors contributing to them. Other PRA tools had been administered and subsequently been quantified for facilitating the objective analysis and drawing thereby a logical conclusion.

Abstract
The entomopathogenic bacteria was isolated and used for mass production to assess the optimum temperature, cell concentration and the incubation period required to cause mortality of termites. Therefore mortality at variable levels of temperature; using different cell concentration and variable incubation period to cause optimum mortality of termites was assessed. High mortality of termites and lowest LT 50 values were recorded by Bacillus thuringiensis. Cell concentration of entomopathogenic bacteria viz B. subtilies, B. cereus, P. florescens, S. aureus and B. thuringiensis, 105, 106, 107, 108, 109 and 1010 were used. At 109 cell concentration mortality was high. Among five bacterial isolates screened B. thuringiensis showed very high mortality of termites and Probit analysis showed in B. thuringiensis recorded the lowest LC 50 at cells concentration of 109 i e (36.87 × 109 cfu ml-1) in worker. Among soldiers also a similar trend was observed at 109 cfu/ml, lowest dosage-mortality LC 50 42.27 × 109 cfu ml-1. Initially low mortality at 1 week and gradually increased and it was more at 2 weeks.

Abstract
Association and path coefficient analysis were studied among 15 agro-morphological traits in 30 green maize germplasms. In general, genotypic correlations were greater than their respective phenotypic correlations. The green ear yield was found to be correlated strongly with ear diameter, ear length, cob length, cob diameter, ear insertion height and green fodder yield. However, it had significantly negative correlations with days to 50% tasseling, days to 50% silking, turcicum leaf blight reaction, puncture pressure and TSS content. The path coefficient analysis indicated that ear length, ear diameter, ear insertion height and green fodder yield exerted positive direct effects on green ear yield. The character ear diameter had the maximum indirect effect on green ear yield via cob diameter. Correlation and path analysis suggested that more emphasis should be given to genotypes having more of green ear length, ear diameter and green fodder yield for farmer's point of view. However, the quality characters of consumer interest like, TSS content and puncture pressure have negative correlations with the ear yield. The highest correlated response to selection to green ear yield found through green ear diameter and green ear length.

Abstract
Education is the basic right of every individual of a society. The constitution of India made education a compulsory thing for every individual of the country and recently included it in fundamental rights of the constitution. Importance of education is quite apparent. It is both a stimulus and a response which ultimately lead to development of mankind. Research and Development is directly linked to activity in terms of invention. It is easy to imagine that education, especially higher education, is important to the invention and innovation process. The scope of developing educational institutions is overwhelmingly greater in Kashmir compared to other states of the country as the topography of the valley restricts the development of other industries. Due to the apathy of all concerned that valley is suffering a lot of financial loss and also social embracing at times. The insufficient educational institutions in valley induce a number of students to migrate out of valley for higher education. This imposes a cost which escalates to hundreds of crores annually. All this play a significant part in drain of wealth directly from the valley and multiplier effect indirectly on other production ventures.

Abstract
The study examined the energy use pattern in cotton cultivation under irrigated situations of Raichur district. The investigation revealed that fertilizer was found to be the dominant source of energy contributing 3,206 mega joules (MJ) per acre which accounted for 54.63 per cent of the total energy utilized in cotton cultivation. The total energy utilized for cotton cultivation by small farmers (6,100 MJ/acre) was significantly higher than that of medium (5,890 MJ/acre) and large (5,621 MJ/acre) farmers. The operation wise energy use pattern in cotton cultivation showed that among all the operations, ploughing consumed highest amount of energy (487 MJ/acre) which accounted to 23.88 per cent followed by harvesting (382 MJ/acre) of the total energy utilized for all operations in cotton cultivation. Further, the total cost of input energy was found to be marginally higher in the case of small farmers (Rs. 17,930.42/acre) compared to medium (Rs. 17,456.03/acre) and large farmers (Rs. 15,957.77/acre) in cotton cultivation. The total cost incurred per unit of input energy was 2.92 per MJ in cotton cultivation.

Abstract
The present study is an effort in the direction of having an integrated study of all aspects of production and value chain of underutilized millets (savi and navane). The per hectare total cost of cultivation of savi worked out to be Rs. 7236.92, while the per quintal cost of production worked out to be Rs. 603.08. Gross return realized from one hectare of savi grown by the sample farmers was Rs. 8442.96. The benefit cost ratio worked out to be 1.17 indicating the profitability of savi cultivation in the study area. Per hectare total cost of cultivation of navane worked out to be Rs. 6587.22 and per quintal cost of navane production worked out to be Rs. 470.52. The gross returns realized from navane cultivation were Rs. 7350 per hectare with a benefit cost ratio of 1.22.7. As decorticated grains are costly and seasonally demanded the value addition is found to be attractive and hence there is a need to establish small processing units in the production areas in order to encourage the production of underutilized millets considering their cultural importance.

Abstract
In the state of Karnataka, north Karnataka accounts for the bulk of the total onion production and is distributed throughout the country. A survey was conducted to evaluate the importance, agronomic practices, irrigation, plant protection activities and economic status of onion in Gulbarga region. Forty five onion growers from seven villages belonging to 3 taluks of Gulbarga district were interviewed through a formatted questionnaire. The survey revealed that the crop plays an important role in the economy of the onion growers. An average of 1.08 acres (16%) of their total land was under onion cultivation in the district. Nearly 70 percent sample farmers grown local varieties and more than half chosen yellow cultivar. Because of many constraints like poor quality/costly seeds/ seedlings, non availability of manures, scarce and costly labors, heavy infestation of weeds, erratic power cut, un-scientific usage of chemical fertilizers and plant protection chemicals, poor storage facilities and traditional farming, the average yield was 57 quintals per acre which was very low when compared to international average.

Abstract
The entomopathogenic fungus was isolated from dead termites and used for mass production to assess the optimum temperature, cell concentration and the incubation period required to cause optimum mortality of termites. Therefore mortality at variable levels of temperature was recorded. Mortality at different cell concentration and variable incubation period was recorded. Effect of entomopathogenic fungus grown at different temperatures 18°C, 20°C, 23°C, 25°C, 27°C and 30°C on infectivity to O. obesus. The analysis showed that the termite mortality was initially low and gradually increased and it was more at 25°C. Among four fungal isolates screened B. bassiana and M. anisopliae showed very high mortality of termite mortality and recorded the lowest LT 50 value in M. anisopliae followed by B. bassiana. The mortality was initially low and gradually increased and it was more at 108. Among workers of B. bassiana recorded the lowest LC50 at cell concentrations of 108 i e (27.23 × 108 conidial ml-1) and in soldier recorded lowest mortality LC50 30.72 × 108 conidial ml-1. Mortality was high in 3rd week in B. bassiana and M. anisopliae and recorded the lowest LC 50 values.

Abstract
The present study is an effort to study growth and instability of minor millets in the northern part of Karnataka. The growth in savi area was negative and significant for both sample district (-1.93%) and the state (-5.62%) as a while. Accordingly the production of savi also showed declining trend as indicated by their negative growth rates in case of both district and state level savi production. Growth in navane area, production and productivity was negative for both the sample districts. The decline in area (8.62%) and production (8.69%) was found to be significant in Bellary district. For the state as a whole, the growth rates of navane area (-8.92%) and production (-8.46%) showed significantly declining trend, while growth rate of navane productivity (0.39%) was found to be positive and statistically significant at one per cent probability level. The average savi production for the state as a whole was predominantly due to change in mean area (160.79%) followed by change in mean yield (86.33%). At the state level the stability of navane production was largely attributable to change in mean yield (69.54%).

Abstract
The effect of lead (Pb) on some biochemical constituent’s viz chlorophyll a, b, carotenoids, protein, carbohydrate and proline content of wheat (Triticum aesticum) seedlings were evaluated under 10, 30 and 60 mM concentration. These concentrations significantly affected all the parameters when compared to control. Pb at 10 mM concentration resulted in less significant effect on chlorophyll, a, b and carotenoids, while higher concentration (30 and 60 mM) significantly reduced chlorophyll and carotenoid contents of the seedlings. However, the addition of nitrogen (5mM) somehow minimized the effect of this heavy metal. Nitrogen increased the chlorophyll content of metal treated plants. Almost similar results (like pigment composition) have been observed for protein and carbohydrate contents. The proline content of plants was increased under Pb treatments. In this case, the additional supply of nitrogen in the form of ammonium nitrate decreased proline content of plants treated with Pb. Results of this study are in opinion that above 30 mM concentration of lead in the soil is toxic for cultivation of this valuable crop in this region and farmers should apply the recommended dose of N2 to reduce the lead toxicity for proper growth and development of the plant and ultimately the productivity.

Abstract
A field experiment was conducted during kharif 2009 at Agricultural College Farm, Karekere, Hassan on sandy loamy soil to study the effect of different sources and time of fertilizer application on yield and economics of potato under rainfed condition in Hassan District. The experiment was laid out in a randomized complete block design with four treatments replicated thrice. The potato tuber yield (16.50 t ha-1) with the application fertilizers as per the farmers practice and FYM @ 25 t ha-1 alone (10.92 t ha-1) was significantly lower than that obtained with application of RDF from different sources along with FYM @ 25 t ha-1 (20.64 to 22.24 t ha-1). However, the highest tuber yield of 22.24 t ha-1 was obtained with the application of RDF through DAP, urea and SOP along with FYM @ 25 t ha-1 which was at par with the tuber yield recorded in other RDF treatments. The B: C ratio was maximum in all the treatments (2.16 to 2.55) receiving RDF from different source and time of application over the farmers practice (1.75) and FYM @ 25 t ha-1.

Abstract
A 42 days trail was conducted to study the influence of Hepatocare and Cal-c-care supplementation on the performance of broiler chicken fed on commercial broiler diet. The cumulative body weight gain, feed consumption, feed conversion ratio, livability and net returns were ranged from 2242 ± 47 (T1) to 2290 ± 27 g/bird (T5), 3563 ± 27 (T4) to 3627 ± 36 g/bird (T3), 1.51 ± 0.01 (T4, T5) to 1.54±0.03 kg feed/kg wt gain (T1), 97 ± 3 (T1, T5) to 100 ± 0 per cent (T3, T4) and from Rs. 29.8 ± 2.3 (T4) to 31.4 ± 0.6/bird (T5), respectively. The supplementation of cal-c-care and hepatocare on every alternative day for 42 days period of bird rearing has improved bodyweight gain, feed conversion ratio and decreased the incidence of mortality. Addition of hepatocare and cal-c-care is beneficial for commercial broilers as growth promoter and didn’t notice any adverse effect throughout the study. Hence cal-c-care and Hepatocare can be used at the rate of 4ml/ litre to have better production performance of broilers.

Abstract
An on-farm trial was undertaken to assess the growth performance and economics of goat kids under grazing supplemented with urea molasses mineral block (UMMB) or mineral mixture. Five farmers having at least 3 kids of 3 month age were selected for the study. One selected kid from each farmer has an access for UMMB lick (G-2) for about 30 minutes daily and another kid was fed daily 10g area specific mineral mixture (G-3) while the remaining one was not provided with any feed supplement (G-1). All the three kids in each farmer were taken for grazing along with the other animals. The trail continued for 3 months. The average daily body weight gain was significantly (p <0.01) higher in group 2 (63.19) and group 3 (58.30) than in group 1 (52.70 g/day). The use of UMMB was more economical than mineral mixture supplementation. Smallholder goat farmers thus can be encouraged to use UMMB for better animal performance.

Abstract
A study was conducted to evolve the potential entomopathogens upon collection of samples (dead termites) in Western Ghats of Karnataka. Entamopathogens was isolated, identified and after mass multiplication the isolates were inoculated to three predominant termite species viz Odontotermes wallonensis, Odontotermes brunneus and Odontotermes obesus were observed for 7 days and mortality was recorded. O. wallonensis against entomopathogenic bacteria were screened and the DMRT analysis for B. subtilies, B. cereus, P. florescens, S. aureus and B. thuringiensis and with control (without entomopathogens) of termites both castes of worker and soldier at different time intervals of 12, 24, 36, 48 and 60 hours, respectively. After 36-48 hours exposure period mortality was high in B. thuringiensis and B. cereus was showed some infection. O. brunneus was also showed similar results with high mortality rate at 36-48 hours of exposure period among four isolates viz B. thuringiensis showed high mortality. At 60 hours exposed to B. thuringiensis we found 100% mortality. In O. obesus initially mortality was low but as the time advanced gradually the mortality also increased and it was peak at 36-48 hours after exposed to entomopathogenic bacteria.

Twelve Osmanabadi weaner goat kids of 21/2 to 3 months age were randomly divided into three groups of four animals each. In group 1, kids were sent for grazing in the field along with the flock for 8 hrs. In group 2, kids were offered concentrate mixture @ 1% of body weight in addition to grazing with the main flock.In group 3, kids were maintained under stall and offered ad lib green fodder and concentrate mixture @ 1% of body weight. The trial was lasted for 84 days. The results revealed that the average body weight gain were 55.36 ± 3.40, 74.76 ± 2.63 and 61.25 ± 5.26 g/day/kid in group 1, 2 and 3, respectively and differed significantly (p<0.01) each other. It was observed that the growth rate is higher under grazing with supplementation than that in grazing alone or stall feeding indicating that grazing with supplementation found to be advantageous during rainy season. Hence it can be concluded that semi intensive farming is best to attain better body weight gain and economic returns.

Abstract
Entomopathogenic fungus isolated from samples of insect cadavers that might have died because of a pathogen infection and termite-associated materials from outer and inner parts of termite mounds were collected from the forest nurseries and plantations located at places such as Mudigere Taluk in Western Ghats of Karnataka. The analysis showed the termite mortality was initially low but gradually increased and highest was found at 36-48 hours of exposure period. Among four fungal isolates screened two B. bassiana and M. anisopliae showed 100% of mortality of termites, compared to Penicillium notatum and Aspergillus flavus lowest LT50 values. Odontotermes brunneus also showed similar results with high mortality at 36-48 hours of exposure period among four isolates viz B. bassiana and M. anisopliae showed high mortality at 60 exposures, and resulted 100% mortality by B. bassiana and M. anisopliae with lowest LT50 values. In Odontotermes obesus initially mortality was low but as the time advanced gradually the mortality of termites were also increased and it was peak at 36-48 hours of exposure and low mortality at 60 hours.

Abstract
The commodity exchanges in commodity futures have developed into indispensable and they are found to be more competent in ‘price discovery’ and reassigning the risk. However, successful commodity derivative trading identify for appropriate institutional support and awareness among the commodity producers. The future is certainly glowing for the Indian commodities market. Once the much anticipated institutional participation like NGOs, cooperatives, agribusiness companies enters the market, it will create speculation, arbitration and hedging for all kinds of players in the market. As the market matures and intensify further, we can hope to see the day almost immediately, when Indian commodities market will provide a benchmark for traders worldwide, especially in those commodities where India is a major producer or consumer. The market has made vast progress in terms of technology, transparency and the trading activity which bring liquidity and better price discovery for all players, especially for the retail investors who can stare at commodities as an investment option. Attractively, this has happened only after the Government protection was removed from a number of commodities and market forces were allowed to play their role after solving all these problems through administered price mechanisms. The management of price risk and resource allocation going to attain greater importance in future with the promotion of free trade and removal of trade restrictions in the domestic and global market.

Abstract
Dairy farms and their associated activity can cause different types of pollutions, for example giant livestock farms, which can house hundreds of thousands of pigs, chickens, or cows, produce vast amount of waste, often generating the waste equivalent of a small city. Silage liquor (from fermented wet grass) is even stronger than slurry, with low pH and high BOD is one of these threats to the environment which can create soil, water and other pollutions. These potential harmful impacts can be prevented by more stringent enforcement policy and/or a greater awareness of the polluting potential.

Abstract
The management and monitoring of agricultural and environmental resources and the origin of foods are of increasing importance today. GIS have proved to be important tools in solving problems encountered. Advances in the capabilities of the web language have enabled information providers to include animation and interactive elements in their web sites. These developments have expanded the potential of the GIS world. The internet map server provides a framework for requests and for delivering information to Web browsers from a GIS application on their www server. The result is ready access to maps and information anywhere on the Internet. This system provides agricultural specialist with the elements needed for decision making. The main advantages of geographical information system are; impartiality, rapidly, flexibility. Decision makers have immediate access to cultivated area depending by type of crop, stage of a crop’s growth cycle, yield forecast, technical condition for land preparation etc. This information is absolutely necessary to elaborate short and long term agricultural strategies.
