Not AvailableAn experiment was conducted during 1999-2000 and 2000-01 to study the effect of phosphorus sources, levels and solubilizers on yield, quality and nutrient uptake of soybean [Glycine max (L.) Merr.]-wheat (Triticum aestivum L. emend. Fiori & Paol.) cropping system in alkaline calcareous soils of Udaipur. Phosphorus application through single superphosphate significantly increased the seed yield, oil content and N and P uptake of soybean over Udaipur rock phosphate-single superphosphate (1:1)mixture.However, both the sources performed equally in imparting the residual effect on grain yield of succeeding wheat and thereby the soybean-equivalent yield of the system. Significantly higher N and P uptake of the succeeding wheat crop were recorded due to single superphosphate - Udaipur rock phosphate (1:1) mixture, while higher N uptake of the whole system was recorded under single superphosphate treatment. Significant enhancement in seed yield, protein and oil content and N and P uptake of soybean were recorded upto 38.7 kg P/ha. Application of 38.7 kg P/ha increased the seed yield and N and P uptake of soybean by 13.3, 18.7 and 30.5% over 12.9 kg P/ha respectively. The maximum productivity and N and P uptake of succeeding wheat and system as a whole were recorded at 38.7 kg P/ha application to soybean. An incorporation of farmyard manure @ 10 tonnes/ha with and without phosphorus-solubilizing bacteria significantly improved the yield (9.3 and 7%), quality and N (17.8 and 13.2%) and P (17.5 and 13.4%) uptake of soybean, and yield (9.6 and 7.5%), N (16.7 and 13.6%) and P uptake (15.9 and 12.3%) of succeeding wheat crop and hence the yield of system as whole (9.5 and 7.3%) respectively over phosphorous-solubilizing bacteria alone. Application of 25.8 kg P/ha to wheat crop improved its yield (13.8%) and N and P uptake (20.4 and 38.4%) thus emphasizing the need for P application to both the component crops of the system.Not Availabl

Not AvailableA field experiment was conducted during 1999-2001 on clay loam medium fertility soils of Udaipur Rajasthan. Sole FYM @10 tonnes/ha did not fulfill phosphorus needs of soybean and succeeding wheat crop. SSP as a source of phosphorus significantly improved yield and nutrient content of soybean when compared to SSP+low grade rock phosphate (1:1). However, higher soil P status was recorded in succeedig wheat crop when SSP+ low grade rock phosphate (1:1) was applied resulting in higher yield of succeding wheat crop. Application of 90 kg P2O5/ha increased the yield of soybean by 13.3 percent and succeeding wheat by 5.4 per cent over 30 kg P2O5 /ha. Combined application of FYM + PSB was found superior over FYM alone.Not Availabl

Not AvailableField experiments were conducted at Kota (Rajasthan) during winter between 2005-06 and 2006-07 to evolve an integrated nutrient management strategy for kabuli chickpea. The experiment was laid out in randomized block design with 12-treatment combinations of P (0, 12.9, 25.8 kg /ha), phosphate solubilising bacteria (0, PSB) and FYM (0, 5 tonne/ha) replicated 4 times. Conjunctive use of inorganic P @ 12.9 kg/ha + PSB + FYM had resulted in maximum number of pods/plant (102.6), bolder seeds (31.88 g) and hence higher seed yield (2.53 and 2.80 tonne/ha). It was in parity with 25.8 kg P/ha + PSB + FYM (2.42 and 2.96 tonne/ha) between 2005-06 and 2006- 07, respectively. Harvest index and N uptake followed similar trend. The P uptake increased with the application of P upto 25.8 kg /ha but was on par with 12.9 kg P/ha + PSB + FYM. Integrated use of inorganic P with PSB and FYM also improved N and P status of soil. The maximum net returns were obtained with 12.9 kg P/ha + PSB + FYM (Rs 53,200 /ha) during 2005-06 and with 25.8 kg N/ha + PSB + FYM (Rs 64,870/ha) during 2006-07 but statistically on par with each other during both the years. But highest B:C ratio was recorded under 12.9 kg P + PSB. Consequently higher productivity, profitability and soil health, kabuli chickpea should be fertilized with 12.9 kg P/ha in conjunction with 5 tonne/ha FYM and PSB inoculation.Not Availabl

Not AvailableIrrigation water is scarce and expensive resource constraining crop production in arid and semi-arid region of India. Most producers’ aims to maximize yield per unit of water applied but it requires a better understanding of crop response to various levels of water stress. A field experiment was conducted during2009–2011 to investigate the effect of deficit irrigation through drip irrigation; phosphorus solubilizing bacterial (PSB) inoculation and chloromequat chloride (cycocel) spray on seed cotton yield and water productivity (WP) of cotton. Experimental treatments comprised of three drip irrigation levels designated as 1.0 ETc (full irrigation as control), 0.8 ETc and 0.6 ETc (regular deficit irrigation) which receive 80%and 60% of the 1.0 ETc irrigation, were kept in main plots. The factorial combination of PSB inoculation and cycocel spray were included as good management practices (GMP) in sub-plots. A furrow irrigation treatment was also kept as absolute control. The result reveals that drip irrigation in cotton at 1.0 ETc significantly increased mean seed cotton yield by 33.5% and saved 30% irrigation water as compared to furrow irrigation which recorded 1859 kg ha−1seed cotton yield with 582 mm irrigation water. Deficit irrigation at 0.8 ETc caused 17% water savings with only 6.4% reduction in yield as compared to 1.0ETc. PSB inoculation and/or cycocel spray significantly increased number of bolls plant−1, boll weight and seed cotton weight plant−1over control. The interaction effect of deficit irrigation and GMP was significant on seed cotton yield and water productivity. Therefore, deficit irrigation at 0.8Etc along with PSB inoculation and cycocel spray should be considered as useful tool for water saving and higher yield in arid and semi-arid regions where irrigation water supplies are limitedNot Availabl

Not AvailableA field experiment was conducted during 2005-07 at Kota, Rajasthan to study the effect of intercrop row ratio and fertility levels on chickpea (Cicer arietinum L.) and linseed (Linum usitatissimum L.) intercropping system. The experiment was laid out in 4 times replicated split plot design, where main-plots received 4 cropping systems, viz. sole chickpea, sole linseed, chickpea+linseed (4:2) and chickpea + linseed (5:1) and sub-plots got 3 fertility levels for chickpea and linseed, viz. 100 % recommended dose of fertilizer (RDF) (N20 P17.2 and N30 P6.5), 75% RDF (N15P12.9 and N22.5P4.8) and 50% RDF (N10P8.6 and N15P3.2) applied on area basis. Seed and biological yields of both chickpea and linseed were higher in sole cropping than in intercropping systems. However, the system productivity (chickpea equivalent yield), total LER, net returns and B:C ratio of chickpea+linseed intercropping under both the row arrangements (5:1 and 4:2) were at par with sole chickpea and significantly higher over sole linseed. The highest N and P uptake was recorded under sole chickpea. Reduction in fertilizer dose by 25 and 50% of RDF decreased the seed yield of chickpea by 6.6 and 16.8% during 2005-06 and by 10.1 and 23% during 2006-07, respectively, while reduction in linseed yield was observed only at 50% RDF. Net returns and B:C ratio decreased significantly with the decreasing fertilizer doses. Total LER and LER of component crops recorded improvement with the reduction in fertility level. Competition functions viz. relative crowding coefficient, competition ratio and aggressivity indicated that linseed was dominant over chickpea. Intercropping systems were found more advantageous than sole cropping under reduced fertilizer application.Not Availabl

Not AvailableA field experiment was conducted during rabi season of 2002-03 and 2003-04 in Udaipur, Rajasthan to develop the improved package of practices for durum wheat cultivation in Rajasthan. It was inferred that replacement of old durum variety Raj1555 with HU8498 (Malav Shakti) enhanced productivity and profitability of durum cultivation in the region. This variety exhibited superiority in terms of protein content and sedimentation value. Despite increased operational cost, adoption of cross sowing in combination with higher inputs (125% recommended seed rate + 125 % Recommended fertilizer dose) gave highest productivity (57 q/ha grain) The adoption of furrow irrigated raised bed system (FIRB) did not provide any additional gain in productivity and profitability.Not Availabl

Not AvailableThe study was conducted for the evaluation of soil suitability criteria for soybean crop in Udaipur district (AERS 4.2) of Rajasthan. Ten farmers' field were selected with varying soil texture, depth and slope. The yield was monitored consequently for three years during kharif season of 2004, 2005,2006. Multivariate regression model was developed and evaluated. It was inferred that shallow , moderately shallow and sandy loam soils were not suitable for growing soybean crop whereas deep clay loam and clay soils were suitable. Besides, AWC, management factors viz., hoeing, weeding and plant population also played important role in influencing crop yield. The simulation of spatially distributed soybean yield was strongly affected by the soil variability within the region.Not Availabl
