Abstract
A field experiment was undertaken in the Campus of College of Agriculture, Orissa University of Agriculture and Technology, Bhubaneswar, during kharif 2008. Recommended dose of N, P, K, biofertilizers and amendments showed significant effect on nutrient uptake, postharvest soil properties and nutrient recovery in case of spinegourd crop. Spinegourd plant treated with biofertilizer (azotobacter + azospirillum + phosphate solubulizing bacteria + arbuscular mycorrhiza @6 kg/ha) + chemical fertilizer (N, P, K @ 70:40:60 Kg/ha) + amendment (lime @ 20% LR i e 1 t/ha applied to the soil) produced higher yield which is significantly superior than the control due to maximum utilization of N, P and K which results in increased vegetative growth which has been reflected in higher foliage production, taller plant, more production of fruits and finally the yield along with higher recovery of nutrients.

Abstract
The present study reveals that the occurrence, distribution and colonization of mycorrhizal fungi in different cotton seed varieties collected from 25 places of Mahabubnagar District, Andhra Pradesh. Direct correlation was observed between the mycorrhizal colonization and the number of Arbuscular mycorrhizal spores. Mycorrhizal colonization was drastically effected by seed variety and not with the soil type. The maximum colonization was recorded with Mahyco seed variety from Jadcherla (Malleboinpally) and Achampet (uppununtala) samples which was cultivated in black and red soil and least infection was found in Kanak variety, which cultivated in red soil of Timajipet (Avancha). Qualitatively and quantitatively Glomus species was dominated in all type of soils. The combination of Glomus along with Scutellospora and Gigaspora has shown maximum mycorrhizal infection.

Abstract
In present investigation an attempt has been made on regeneration and multiple shoot induction from meristamatic tissues like seedling coteledonary nodal explants in MCU-11. Improvement of regeneration method to induce the efficient transformation system is very important in many Indian local cotton cultivars are desirable. However, in the previous reports rooting efficiencies were genotype independent and the data was inadequate. The objective of the investigation is to improve shoot initiation, multiple shoot induction, in vitro grafting for the un rooted micro shoots for maximum recovery of regenerated shoots with 90% for greatly improve the crop yield and gene transfer of desirable genes for biotic and abiotic aspects of cotton.
