Bioconversion of agrowaste is an environment friendly and safe method for the disposal and recycling of organic wastes. Composting process to produce quality compost within short duration may be valuable in recycling agrowaste in organic manure to improve soil fertility. Microbial consortium of efficient biodegrading strains consisting amylolytic (A-6) and proteolytic bacteria (P-3), cellulolytic actinomycetes (C-3) and pectinolytic fungus (PC-15) with and without mustard cake amendment was used for degradation of pigeon pea stover, chickpea stover, mustard stover, sugarcane trash and cotton stover. Microbial inoculation along with mustard cake amendment accelerated composting and increased total nitrogen per cent and humus content of the compost and also decreased the pH value and total organic carbon content in composted crop wastes in 60 days of decomposition.

The experiment was conducted during rainy (kharif) and winter (rabi) season of 2006-07 and 2007-08 at Arjia, Bhilwara to evaluate the direct and residual effect of integrated nutrient management practices on blackgram and succeeding Indian mustard under sub-humid southern plain and Aravalli hills region of Rajasthan. Integrated nutrient management showed significant influence on productivity and nutrient uptake of blackgram. Application of 25% RDF + FYM 2.5 tonnes/ha along with Rhizobium + PSB registered maximum improvement in seed yield (1 342 kg/ha) which was 18.2% higher than 100% RDF. Treatment receiving 75% RDF with vermicompost 0.63 tonnes/ha gave maximum Nand P uptake. Residual effect of integrated nutrient management practices was also equally effective in improving the yield and nutrient uptake of mustard. Application of FYM 5 tonnes/ha along with Rhizobium + PSB recorded the highest seed yield of mustard (1 642 kg/ ha), followed by treatments receiving 25% RDP + vermicompost 1.25 tonnes/ha with Rhizobium + PSB (1 600 kg/ha) and 25% RDF + FYM 2.5 tonnes/ha with Rhizobium + PSB (1 594 kg/ha). Similar trend was also observed for N and P uptake. Maximum net returns (Rs 50 342/ha) with B: C ratio (3.2) was obtained from treatment receiving 25% RDF + FYM 2.5 tonnes/ha with Rhizobium + PSB.

A study was conducted with different interspace crops and cropping systems on cultivated waste land under rainfed condition at Bhilwara. In newly established aonla (Emblica officinalis) orchard, different field crops (maize, greengram and sesame), vegetables (kachri, pumpkin and sembean), medicinal crops (ashwagandha, sonamukhi and azwain) and pasture crops (Cenchrus spp., Stylo hamata and Cenchrus+Stylo) were grown in kharif season and in rabi season taramira crop was grown on conserved moisture and soil improvement practices. There was no marked difference on growth and yield of aonla due to interspaced crops. During kharif, among the interspaces, sesame, pumpkin, sonamukhi and Stylosanlhesis hamata recorded highest maize grain equivalent yield (MGEY) of 1683, 4168, 1715 and 638 kg/ha, respectively. Further, under moisture conservation practices disc plough was found most effective to produce highest MGEY of taramira (800 kg/ha). However, under soil improvement practices, green manuring+gypsum produced maximum MGEY of taramira (778 kg/ha). Similar trend was also observed for net returns and B: C ratio. Among the field crops, sesame gave maximum net returns (Rs. 34132/ha) with B: C ratio 2.90, whereas in vegetables, pumpkin gave maximum net returns (Rs. 66822/ha) with B: C ratio 4.56. However, in medicinal crops, sonamukhi gave maximum net returns (Rs. 46560/ha) with B: C ratio 3.51 and among the pasture crops, S. hamata recorded maximum net returns (Rs. 29912/ ha) and B: C ratio 3.42. During rabi, taramira crop was grown with the soil moisture conservation practices, whereas maximum net returns (Rs. 29210/ha) were observed with Rotavator with B: C ratio 2.95 and in soil improvement practices with green manure+gypsum recorded maximum net returns (Rs. 28482/ha) with B: C ratio 2.62.

Results of field experiment, conducted to study the effect of P and Zn application on growth, yield, and nutrient uptake of barley in loamy sand soils under irrigated conditions of hyper arid plains of Rajasthan, indicated that dry matter accumulation at different growth stages and number of tiller/m row length increased significantly up to 19.7 kg P/ha, however, plant height increased only up to 13.1 kg P2O5/ha. Yield attributes namely effective tillers/m row length, ear length and grains/ear increased significantly up to application of 19.7 kg P 2O 5/ha resulting in significantly higher grain that was 28.9% higher than control. N content in grain, crude protein content in grain total uptake of N and P and net returns and B: C ratio increased significantly up to application of 19.7 kg P/ha. N and protein content in straw, P content in grain and total uptake of K increased significantly up to application of 13.1 kg P/ha. Zn content in grain and straw and total Zn uptake decreased significantly with the P application. Application of 30 kg ZnSO 4/ha significantly improved the growth and yield characters namely plant height, plant dry matter accumulation at different growth stages and number of effective tillers/m row length, ear length and grains/ear and grain yield increased by 29.5% over control. N content in grain and straw, Zn content in grain and straw and total uptake of N and Zn and net returns increased up to application of 30 kg ZnSO 4/ha. However, total uptake of P and K increased only up to 20 kg ZnSO 4/ha. The highest B: C ratio was obtained with the application of 10 kg ZnSO 4/ha. On the basis of regression analysis, the optimum dose of P and Zn were worked out to be as 25.07 kg P/ha and 35.11 kg ZnSO 4/ha.

A field experiment was conducted in split plot design with three replications during winter and rainy seasons of 2003 to 2005 at Bikaner to study the effect of phosphorus (P) levels (0, 8.7, 17.5 and 26.2 kg/ha) and zinc [0, 2.5, 5.0 & 7.5 kg soil application, 0.25%, 0.5% ZnSO 4 foliar spray once (45 DAS) twice (45 and 60 DAS)] applied to fenugreek, on the performance of fenugreek (Trigonella foenum-graecum) - pearlmillet (Pennisetum glaucum) cropping system. Application of 17.5 kg P/ha and 5.0 kg Zn/ha resulted in 24.7 and 14.7% higher seed yield of fenugreek, when compared with control (0.77 and 0.85 tonnes/ha). Residual effects of 26.2 kg P/ha and 7.5 kg Zn/ha applied to fenugreek increased grain yield of pearlmillet by 62 and 22%, respectively. Application of 26.2 kg P/ha and 7.5 kg Zn/ha to fenugreek significantly increased the content and uptake of P and Zn fenugreek and pearl millet. However, increasing levels of either of these two nutrients was found to have depressive effect on content and uptake of other by fenugreek. Combined application of 26.2 kg P/ha + 7.5 kg Zn/ha resulted in the highest yields of both the crops. The net returns and B: C ratios were also highest in 26.2 P and 7.5 kg Zn applied treatments.
