Abstract
An estimated 2 billion people in developing word suffer from iron deficiency and around 3 million children die as a result of vitamin A deficiency. Fourteen million children suffer from clinical eye problems and increased risk of respiratory diseases and diarrhea. Making staple foods more nutritious through biofortification, a process of enriching crop plants with nutrients is new approach to control vitamin and micronutrient deficiencies. Rice, which is staple food for more than half the world’s population and billions of the poor population in the developing world, is an ideal staple crop to biofortify. This is possible through breeding approach i e exploring possibility of gene transfer for improving micronutrient density in grains and agronomical biofortification through adequate supply of mineral nutrients. Both these approaches would result in a new paradigm for improved nutrition particularly in the developing countries.

Abstract
A study was undertaken in Baramulla district of Lesser Himalayas (Jammu and Kashmir) to map the spatial variability of DTPA extractable micronutrients and their relationship with other important soil properties. Six hundred and seventy six (676) geo-referenced surface soil samples (0.2 m) were collected using SOI (1:50,000 Scale) by random grid sampling from the district. These soil samples were analyzed for DTPA extractable micronutrients (Zn, Fe, Mn, and Cu) and were categorized as deficient, sufficient and adequate as per the criteria followed in the soil testing laboratories. The DTPA-Zn in soils varied from 0.04 to 9.90 mg kg-I, DTPA-Cu from 0.00 to 16.15 mg kg-I, DTPA-Fe from 0.55 to 99.88 mg kg-1 and DTPA-Mn from 0.16 to 43.50 mg kg-1. None of the samples were found to be deficient in iron and copper. The relationship between micronutrient contents in soil was significant. There is a need to refine the critical level of deficiency for DTPA-Fe with reference to growing environment, certain soil characteristics and pre-defined plant parts of specific crops. Soil micronutrient maps prepared in Arc Info GIS clearly delineated the specific locales where micronutrient problem constrained crop production. Multi-micronutrient map suggested that deficiency of individual element is more prevalent as compared to that of two or three micronutrients. DTPA extractable micronutrients showed positive correlation with organic carbon and clay. The positive influence of organic carbon on micronutrient availability was maximum for DTPA-Cu. The pH and CaCO3 had negative influence on the availability of Zn, Mn and Fe. The results indicated that Zn is likely to constraint crop production, followed by Mn in the soils of Baramulla district.

Abstract
A field experiment was conducted during kharif 2013 to evaluate the effect of phosphorus (P) levels and their solubilizers on maize, available soil phosphorus and microbial population in maize rhizosphere under temperate conditions of Kashmir valley. Three levels of biofertilizers (Control, PSB and VAM) in combination with four levels of inorganic phosphorus fertilizers (0, 25%, 50% and 100%) RDF laid out in randomized complete block design with three replications. The maximum biomass production (104 q/ha), grain yield (46.00 q/ha) were recorded in VAM + PSB + 50% RDFP which was statistically at par with PSB + 100% RDFP. Application of VAM and PSB in combination with different levels of P increased the P availability in soil. However, the maximum P availability (16.00 kg/ha) was recorded by PSB + 100% RDFP, which was statistically at par with 100% RDFP, VAM + 100% RDFP and VAM + PSB + 50% RDFP. The application of VAM and PSB in combination with different levels of P increased the P uptake over control. The maximum uptake of P (29.1 kg/ha) was recorded in the treatment combination VAM + PSB + 50% RDFP, respectively. Significantly higher vesicular arbuscular mycorrhizal (VAM) spore density and viable counts of phosphate solubilizing bacteria (PSB) were recorded with the co-inoculation of (VAM + PSB + 25% RDFP) over rest of the treatments.

Abstract
The field experiment was conducted on saline soils in Roogi village of Mudhol Taluk, Bagalkot district situated in the northern dry zone (Zone-III) of Karnataka, India during 2012 kharif. The experiment comprised of four salinity levels (ECe <2 dSm-1, ECe 2-4 dSm-1, ECe 4-6 dSm-1 and ECe 6-8 dSm-1) and four nitrogen levels (150 kg N ha-1, 175 kg N ha-1, 200 kg N ha-1 and 225 kg N ha-1). Application of higher doses of nitrogen resulted in increased yield. The highest yield of 8.31 t ha-1 was obtained under <2 dSm-1. Soil application of 225 kg N ha-1 recorded maximum yield (6.74 t ha-1) and it was closely followed by the 200 kg N ha-1. Grain protein content decreased with increasing soil salinity whereas starch content increased with increasing salinity. Influence of higher doses nitrogen was not observed on both starch and protein content under saline compared to non saline soil conditions.

Abstract
Maize is one of the important cereal crops as far as India is concerned. Large number of hybrids have been released for cultivation in all the zones of the country by public and private sectors. Acharya N. G. Ranga Agricultural University has released promising hybrids for Andhra Pradesh in the last few years. It is strongly felt that the hybrids and the parental lines need to be protected for the reasons of Intellectual Property Rights. Six inbreds and five hybrids have been fingerprinted with 100 SSR markers. Polymorphism has been sufficiently detected by the SSR markers. However, few markers were specific in identifying the inbreds/hybrids. The molecular IDs for the material used under the study have been developed. The variation in the expected polymorphism has been explained with the citations from already available literature. These fingerprints can be used to protect the ANGRAU developed inbreds/hybrids.

Abstract
This study has been conducted to determine nature and magnitude of genetic variability and association among yield and its contributing traits for development of superior varieties of black gram. Therefore, 35 diverse accessions of black gram were evaluated in a randomized complete block design for various agronomical and physiological characters during kharif 2013. Analysis of variance revealed the existence of significant differences among genotypes for all characters studied. The magnitude of PCV and GCV was moderate to high for plant height (cm), number of cluster per plant, and seed yield per plant (g). High heritability coupled with high genetic advance as percent of mean was observed for seed yield per plant indicating the role of additive gene in expressing these traits. Seed yield per plant showed significant and positive correlation with number of pod per plant and number of seed per pod to be considered for realizing the improvement in yield. Pattern of diversity among accessions was also estimated using Wards minimum variance dendrogram and principal Component analysis for important agro-morphological traits. Dendrogram generated four clusters viz cluster I contained 9 accessions, Cluster II contained 8 accessions, Cluster III contained 10 accessions and Cluster IV contained 8 accessions. Hence, selection based on these traits may be effectible for further crop improvement program.

Abstract
They study was undertaken to monitor the viability of herbal seed treated sesame seeds stored under different containers in the Department of Genetics and Plant Breeding, Annamalai University, Annamalai Nagar. Genetically pure seeds of sesame cv. TMV 3 were obtained from the Oilseed Research Station, Thindivanam. The bulk seeds were graded for uniformity using appropriate round perforated metal sieves of sizes of 5/64" size sieve and were imposed with various pre-storage herbal extract seed hardening treatments. The treated seeds were dried under shade and in drying chamber to reach required moisture content for storage. The treated seeds along with control were stored in cloth bag and 700 gauge polythene bag under ambient condition of Annamalai nagar for a period of 12 months and were evaluated for seed quality characters viz moisture content, germination percent, speed of germination, root length, shoot length, electrical conductivity and dehydrogenase enzyme activity at bimonthly intervals. The study revealed that after twelve months storage, the sesame seeds treated with 20% chicory herbal leaf extract and stored in 700 gauge polythene bag registered higher germination percentage, seedling length, dry matter production and dehydrogenase enzyme activity and low electrical conductivity when compared to other treatments and control. This type of herbal extract pre-storage seed treatment maintained the minimum seed certification standard upto 12 months in this oil seed crop.

Abstract
Bacillus thuringiensis is a gram-positive, spore forming bacterium and it produces protein crystalline inclusions called Cry proteins during the stationary phase. The Cry genes encoding for Cry proteins are mostly carried on plasmids of different sizes (4-150 Mb) but they have also been reported to found on chromosome. In this study a total of 39 Bacillus thuringiensis strains were isolated from 20 soil samples collected from different regions of Karnataka state, India. For total DNA (both plasmid and chromosomal) extraction of these isolates we modified the total DNA extraction method of and obtained a total DNA of high quality and quantity, which is suitable for subsequent PCR. In the modified method we used both lysozyme and SDS for the lysis of the bacteria cell and some steps of extraction protocol were modified to remove protein contamination. The mean amount of DNA extracted with modified method was 1013.11 ng/μl. Isolate Bt-17 was found to contain highest concentration of DNA (1851.5.5 ng/μl) while Bt-3 produced lowest DNA concentration (354.8 ng/μl). The UV spectrophotometric and gel electrophoresis analysis resulted in high A260/A280 ratio (1.88) with high intactness of DNA. Subsequent evaluations were performed by PCR using Cry gene specific primer.

Abstract
Greengram (Vigna radiata L. Wilczek), is an important pulse crop of India that suffers from many biotic and abiotic constraints. Green gram recalcitrant towards in vitro regeneration significantly hampers the possibilities of genetic improvement. Therefore it is essential to develop a rapid reproducible protocol for in vitro regeneration which is basic for genetic transformation. Efficient in vitro regeneration of green gram cv Sujata was achieved through direct organogenesis using cotyledonary node (with cotyledons) explants excised from 5 days old seedlings raised on MS medium containing 0.5 mg/l BAP. Shoot bud regeneration was achieved on B5 medium supplemented with 1.0 mg/l BAP within 2 weeks of subculture. The number of shoots per culture varied from 2.00 to 16.75 in different growth media. The elongation of shoots was obtained on B5 medium supplemented with 0.1 mg/l BAP. The elongated shoots were rooted on ½ strength B5 medium within 8 days of culture. The rooted plantlets were transferred to plastic bag containing, soil:sand:FYM (1:2:1) for hardening and kept in the greenhouse with 85% relative humidity. This protocol offers a good potential for genetic improvement using gene transfer techniques.

Abstract
In a study conducted at Floricultural Research Station, Rajendranagar, Hyderabad, during 2012-13, marigold loose flowers of cv. Pusa Narangi Gainda harvested from the plots, pre-harvest sprayed with salicylic acid @ 200 ppm, Ca (NO3)2 @ 2% and CaCl2 @ 2% along with control (water spray) were used for packaging and storage studies. The study involved the packaging of flowers in onion mesh bags and polyethylene (PE) bags of 200 gauge thickness with 0, 1, 2 and 3% ventilation and storage at ambient conditions and at 10°C. The results revealed that packaging of the flowers in PE bags with 0% ventilation resulted in minimum physiological loss in weight (PLW) of flowers with extended shelf life at both storage conditions. The flowers packaged in 0% ventilated PE bags were stored for 4.63 days under ambient conditions and for 14.04 days in cold storage at 10°C. Further, even though the packaging was found to be the dominant factor affecting the post-harvest behaviour of flowers at storage than the pre-harvest sprays in this study, the treatment pre-harvest spray with Ca (NO3)2 @ 2% stood best affecting the shelf life of flowers among all other treatments.

Out of these, 5 genotypes were categorized as highly resistant, 128 as resistant, while 82 as moderately resistant and rest as moderately susceptible and susceptible to BPH. The average plant damage score of highly resistant genotypes was ranged from 0.50 to 0.91 whereas 1.00 to 2.98 in resistant and 3.01 to 5.00 in moderately resistant category. The average probing marks per seedling was ranged from 12.00 to 35.00. The genotype R1723-1413-357-1 had the highest (35.00) average probing marks followed by R1959-173-3-27-1 (31.80), R1600-1124-3-619-1 (31.20), BP10625-BB4-19-BB8 (30.80) and IR64 (30.60). The minimum average probing marks per seedling (11.30) was observed in susceptible check TN1. Significantly higher number of probing marks was found in all resistant genotypes as compared to susceptible check TN1. As regards to days required to wilt due to BPH feeding, the genotype IR78554-145-1-3-2 required the maximum days (35.80) followed by R1959-173-27-1 (35.60), IR64 (35.20) and Ganjeikalli (32.80). All the resistant genotypes had significantly higher number of days required to wilt in comparison to susceptible check TN1.

Abstract
There were thirteen treatments which comprised single application of different post-emergence herbicides either alone or in combination and hand weeding was conducted on clayey Vertisols soil of College of Agriculture, Raipur during kharif season of 2012. Echinochloa colona among grasses, Cyperus iria among sedges and Alternanthera triandra, Eclipta alba and Phyllanthus urinaria among broad leaf weeds were dominant. Application of metsulfuron methyl + chlorimuron ethyl and ethoxysulfuron alone was found most suitable for weed control without any harm to the crop. The combined application of cyhalofop-butyl or fenoxaprop-p-ethyl with metsulfuron methyl + chlorimuron ethyl exhibited the appreciable lower total weed density. Hand weeding twice recorded highest weed control efficiency. Hand weeding twice recorded the highest grain yield and net return. Application of ethoxysulfuron registered the highest B:C ratio which was at par with metsulfuron methyl + chlorimuron ethyl and hand weeding twice.

Abstract
A field study was carried out under rainfed conditions during rabi 2012 to study the genetic variability, heritability and expected genetic advance for eight traits in 78 bread wheat genotypes. The genotypes exhibited wide range of variation for all the traits except for plant height, indicating the presence of enough genetic variability in the material under study. Genetic coefficient of variation ranged from 7.56 for protein content to 52.38 for grain yield per plot. All the traits exhibited high heritability, however very high values of heritability were observed for sedimentation value (99%), plant height (99%) and days to heading (97%). The traits sedimentation value and grain yield per plot showed high heritability and genetic coefficient of variation along with high genetic advance. Therefore, these traits could be considered as suitable selection criteria to develop high yielding genotypes with high sedimentation value. Thus, these characters may be effective as selection indices during breeding programme for improving grain yield and quality.

Abstract
Field experiment was conducted during the kharif seasons of 2011 and 2012 at Bihar Agricultural University, Sabour (Bihar) to evaluate the effective and economics integrated weed management method in maize. Weed management had a positive influence on growth, yield attributes and yield of maize. Manual weeding at 15 and 30 days after sowing (DAS), zero tillage ( ZT)-glyphosate pre plant followed by atrazine+ halosulfuran (1.0 kg + 90 g a.i./ha) as post emergence, conventional tillage(CT)- atrazine + halosulfuran @ (1.5 kg + 90 g a.i/ha) as post emergence and zero tillage (ZT)- glyphosate pre plant followed by topramezone + atrazine @ (40 ml + 500 g a.i/ha) as post emergence proved equally effective in increasing most of the growth parameters, yield attributes, yield and economic advantage. The effect due to different weed management practices on grain yield of maize was significant. The maximum mean grain yield of 6.82 t/ha was recorded from the plots where two hand weeding at 15 and 30 DAS was performed and was statistically at par with the mean grain yield obtained under different weed management practices i e ZT-glyphosate pre plant followed by atrazine + halosulfuran (1.0 kg + 90 g a.i./ha) as post emergence POE (6.71 t/ha), CT- atrazine + halosulfuran @ (1.5 kg + 90 g a.i/ha) as post emergence (6.41 t/ha), ZT-glyphosate pre plant followed by topramezone + atrazine @ (40 ml + 500 g a.i/ha) as post emergence (6.36 t/ha), and the grain yield obtained under these were significantly superior to the grain yield obtained under rest of the weed management practices. Treatments CT- atrazine @ 1.5 kg a.i/ha as pre-emergence (6.14 t/ha), CT-halosulfuran @ 90 g a.i/ha as post emergence (6.26t/ha) and CT- topramezone+atrazine @ (40 ml + 500 g a.i/ha) as Post emergence (6.27 t/ha) were at par with each other. Significantly lowest mean grain yield of 5.10 t/ha was obtained from weedy check treatment. Yield advantages due to different weed management practices over weedy check were mainly attributed due to enhance yield attributing parameters as a result of lower weed population, biomass along with higher weed control efficiency. The highest net return ` 34856/ha was noted in the treatment ZT-glyphosate pre plant followed by topramezone+atrazine @ (40 ml + 500 g a.i/ha) post emergence and maximum benefit: cost ratio of 1.24 was obtained in treatment ZT-glyphosate pre plant followed by maize + black gram as intercrop and lower value of net return ` 22980/ha and benefit: cost ratio of (0.82) were recorded under treatment weedy check.

Abstract
Production of inoculum for ergot pathogen and the disease incidence on fodder sorghum at eight different locations of Gulbarga (Karnataka) and one location in Latur (Maharashtra) district were carried out during the year 2012. Percentage of disease incidence was estimated by examining sorghum ear heads following random row counting method. The latitude and longitude of the locations were recorded using GPS enabled Smartphone and photographs of farmer’s fields showing ergot disease symptoms were taken. Ergot disease incidence was highest in sorghum fields at Wadhona (100%), followed by moderate incidence at Hagarga (33.6%), Syed Chincholi (19.5%) and Sannur (18.2%) as compared to the lesser incidence at Jambga village (8.4%), Aland (7.5%), Basavakalyan (5%) and Aurad (3.2%). The disease was observed on fodder sorghum grown during late kharif season. The fodder sorghum was grown as mixed crop mainly with pigeon crops. Rabi grown grain sorghum crops were free from ergot disease. Ergot contaminated debris and grains of fodder sorghum along with sclerotia, microconidia and macroconidia act as source of inoculum for the subsequently sown kharif grain sorghum. Many farmers in the area practice crop rotation with pigeon pea followed by grain sorghum. Therefore the ergot infected fodder sorghum grown as mixed crop with pigeon pea acts as source of inoculum for the subsequently grown grain sorghum during kharif season.

Abstract
The present study was conducted in the Malaprabha command area as many scientific irrigation methods were implemented by the RKVY project. The required data were collected from the 35 farmers each practicing border strip method of irrigation (scientific) and furrow methods of irrigation (traditional) in the cultivation of maize. The study revealed that the adopters of scientific irrigation technology produced 14.83 percent higher income from border strip method of irrigation than furrow irrigation. The increase in the income was further decomposed into different sources of change such as adoption of scientific irrigation technology and changed input levels. The scientific irrigation technology alone could contribute 21.03 percent increase in income, while the contribution of change in input levels was found to be negative (-6.20%). Amongst the various inputs, fertilizer (-1.58%), human labour (-0.66), bullock and machine labour (-0.68%), cost of irrigation (-5.12%) and FYM (-0.23%) contributed negatively where as seed (0.75%) contributed positively to the income.

Abstract
The present paper attempts to examine the economics of dairy farming, resource productivity, resource use efficiency and return to scale of crossbred cow milk production on small farms in Parbhani district of Marathwada region of Maharashtra state. A sample of 30 farmers was selected through multistage sampling technique from Parbhani district and data collected during November-December 2012. The total cost of maintenance of one crossbred cow per annum was worked out to ` 47167.52 of which ` 30833.13 was variable cost and ` 16333.28 was fixed cost. Whereas output- input ratio was observed as 1: 1.42. The Cobb Douglas production function approach was used to measure the resource productivity, resource use efficiency and return to scale by calculating and comparing Marginal Value Products (MVPs) and MVP to factor price. Results depicted that on small farms, only dry fodder (2.6679*) was found positively significant, However, concentrate (-2.6095*) was found negatively significant. In regard to resource use efficiency of small farm, green fodder (-2.968), concentrate (-0.049) and medicine cost (-0.0003) were excessively utilized. Human labour (8.7658) was underutilized and dry fodder (0.994) was used optimally. The result also indicates that return to scale on small farm was increasing (∑bi: 2.397).

Abstract
Sclerotia were collected during December 2012 from a sorghum field near Wadhona village of Udgir taluk, Latur district, Maharashtra, India. Both the long and short sclerotia were buried in Petri plates having moist sterilized black cotton soil at 0.5 cm depth and incubated under ambient conditions with temperature ranging from 18°C to 23°C. The soil in the Petri plate was watered regularly to maintain moisture. After 23 days of incubation in moist soil, the long sclerotia germinated showing clavicipitaceous stipe and capitulum. The short sclerotia failed to germinate. The germinated stromal heads with stipes were harvested and preserved in FAA to study their histological features. Using microtome machine the longitudinal sections of stipe and capitulum were taken. An average diameter of capitula ranged from 0.1 to 0.08 mm, perithecia were of 57.4 mm -119.6µm × 43.3-80.0µm, asci 58.2-142.2µm × 2.5-3.4µm, ascospores 40.0-87.0µm × 0.4-0.6µm. The present report is the fourth one from India in the past 66 years. A few years ago it was believed that C. sorghi has disappeared from India or it is replaced by C. africana. The present communication proves its prevalence in South India and restricted to a few locations in Maharashtra, Andhra Pradesh and Karnataka.

Abstract
The present investigation was carried out with pigeon pea to understand the association among the yield components and their direct and indirect effects on the seed yield. The estimates of genotypic correlation coefficient in general were higher than their corresponding phenotypic correlation coefficients indicating strong inherent association among the traits. The characters association studies indicated that number of pods, secondary branches per plant, plant height, primary branches per plant showed significantly positive correlation with seed yield at genotypic and phenotypic levels. The path analysis indicated that the number of pods per plant exerted the highest positive direct effect (0.853) on grain yield per plant followed by water absorption (0.80), protein content (0.69), number of secondary branches per plant (0.607), number of primary branches per plant (0.184) and time taken for cooking (0.163). Days to 50% flowering recorded highest indirect effect on the yield per plant via days to maturity (0.22), test weight (0.191), number of secondary branches per plant (0.150), number of primary branches per plant (0.102), dhal recovery (0.098) and protein content (0.048).

Abstract
The present investigation conducted 42 F1s developed through full diallel by using seven okra lines namely, P1-AE 64 (White), P2-AE 64 (Pink), P3-AE 65 (White), P4-AE 65 (Pink), P5-AE 66 (Pink), P6-AE 70 (White) and P7-AE 71 (White) in randomized block design with two replications. The parents P1 and P4 were the best general combiners as it showed desirable GCA effects in favourable direction for most of the traits. Genotypes i e P1 (82.84), P6 (69.42) and P4 (41.27) were good general combiner for yield appear to be worthy of exploitation in future breeding. It is suggested that involving these lines may be developed through multiple crossing to isolating high yielding varieties. The highest SCA effects in desirable direction observed in P2 × P4 for days to first flowering (-2.45), total fruit yield per plant (89.88), number of fruits per plant (5.98), total phenol content (0.08) and polyphenoloxidase activity (0.15), P1 × P2, P6 × P1 and P1 × P4 showed desirable SCA effects in favourable direction. The best general combiners P1, P4 and desirable cross combinations P2 × P4, P1 × P4, P1 × P2 can be further used in the breeding programme for okra crop improvement.

Abstract
Rice plant hoppers have been an important menace to rice in Asian countries not only because of their severe damage due to their abundance but also of their ability to transmit virus diseases of this important food plant. Field experiment was conducted at research farm of Indira Gandhi Krishi Vishwa Vidyalaya, Raipur during kharif season 2013-14. Standard design of light trap (SM-84 model) was used to collect valuable information on seasonal activity of both major pest species of paddy namely Brown plant hopper, Nilaparvata lugens (Stal.) and white backed plant hopper, Sogatella furcifera (Horvath) and to find out its correlation with weather parameters. Seasonal activity indicated that the Brown plant hoppers adult catches in light trap was started from 27th SMW and remained continued up to 52nd SMW. The highest numbers of adult catches were observed during 47th SMW of November and showed significant negative correlation with morning relative humidity (r = -0.495*) at 5 percent level of significance. The highest numbers of white backed plant hopper, S. furcifera adult catches were observed during 42nd SMW of October afterwards it declined. The results of the correlation studies made on white backed plant hopper population revealed the non significant relationship with weather parameters.

Abstract
Present experiment preparation and storability studies of wood apple squash was carried out during the year 2013-14 at Post Harvest Technology Laboratory, Department of Horticulture, Post Graduate Institute Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola. The experiment was conducted in complete randomized design consisting of seven treatments and three replications with local variety. By evaluating the wood apple squash, organoleptically, it could be observed that the squash prepared with cane sugar from local variety was found to be acceptable up to 120th days of storage in respect to sensory qualities. Further, the experimental data recorded on sensory qualities of wood apple squash, it was found that, among all the treatments, cane sugar T1 exhibited the maximum 7.2 good score on 120th days which may be rated as a superior quality or standard recipe. From the recordings the squash was contaminated by mould growth. At 60th days highest mould count was found in jaggary + honey T6 and total squash was contaminated at 120th days of storage. However, increase in microbial population mainly depends upon the environment available to the microbes and storage temperature.

Abstract
The present investigation were conducted for two Kharif seasons in the farmer field to study the effect of different vegetable intercropping systems on yield, yield parameters and economics of aerobic rice. Results revealed that the significantly higher rain yield (5470 kg ha-1) was observed in sole rice. Among the different intercropping systems, maximum grain yield (5085 kg ha-1) was recorded in rice + amaranthus intercropping systems as compared to other. However, all the growth and yield parameters like productive tillers plant-1 (30.45), panicle length (21.32 cm), panicle weight (3.62 g), test weight (20.34 g) and total dry weight (88.03 g plant-1) was observed in rice + amaranthus. With respect to REY, among the different intercrops, rice + amaranthus recorded significantly higher rice equivalent yield (18007 kg ha-1) compared to sole crop of rice (5470 kg ha-1) and rice + French bean (4716 kg ha-1). Thus, cultivation of rice + amaranthus intercropping is better for higher yield as well as income.

Abstract
A long term experiment was conducted with the objective of assessing the impact of continuous application of chemical fertilizers and manures on properties of soil, key indicators of soil quality and yield under rice - wheat cropping system. The experiment was conducted in randomized block design since 1999 on vertisols at same site and with the same randomization at Raipur in central India as one of the centers of AICRP on long term fertilizer experiment. Results showed that application of 150% NPK recorded highest yield (5065 Kg ha-1) which was on par with 100% NPK+FYM treatment (4855 Kg ha-1). The soil pH and Ec did not change but markedly changed the organic carbon, available nutrient contents of the soil and plant growth parameters. The available N, P and K were gradually depleted in all the treatments but the magnitude of depletion was less in the treatments which received N, P and K respectively. Thus, the balanced use of fertilizers continuously either alone or in combination with organic manure is necessary for sustaining soil fertility and productivity of rice crop.

Abstract
The study is based on the induction of mutations using mungbean cv. K 851. Two mutagens viz gamma rays and sodium azide with different combinations and concentrations were tested for effectiveness. It was revealed that the higher doses of both the mutagens applied alone or in combination severely reduced the germination percentage, seedling height and plant survival in M1 generation. The combination treatments of gamma rays and sodium azide produced more physiological damage as compared to the single treatments of mutagens while low to moderate doses of mutagens were effective in inducing changes for the most the economic important traits. Maximum inhibition in seed germination percentage, plant survival percentage and seedling growth was recorded with the combination treatment of γ60 kR + SA 0.06%.
