Background: Soybean is an important legume as well as oil seed crop grown in a varied range of climate and soils. Phosphorous and sulphur is an important macronutrient required for plants. Their deficiency in soil is a worldwide concern for production of food crops. Therefore, present investigation was done to study influence of phosphorus and sulphur fertilization on productivity, profitability and quality of soybean. Methods: An experiment conducted during kharif 2021 and laid out in factorial randomized block design with three replications having four levels of phosphorous (0, 20, 40 and 60 kg ha-1) and three levels of sulphur (15, 30 and 45 kg ha-1). The data was recorded, analysed and computed statistically. Result: The results indicated that application of 60 kg P2O5 ha-1 and 45 kg S ha-1 gave significantly higher yield, monetary returns and quality of soybean over rest of phosphorous and sulphur levels. However, it was found at par with 40 kg P2O5 ha-1 and 30 kg S ha-1.

An experiment was conducted at Instructional Farm, College of Agriculture, Ummedganj, Kota during kharif, 2021. The twelve treatment combinations comprised of four levels of phosphorus viz., 0, 20, 40 and 60 kg ha-1 allocated in main plots and three levels of sulphur viz., 15, 30 and 45 kg ha-1 in sub plots. Results showed that application of 60 kg P2O5 ha-1 had significant effect on plant height at 60 DAS and at harvest, number of total root nodules plant-1, effective root nodules plant-1 and dry weight of root nodules at 45 DAS, chlorophyll content at 45 DAS and leaf area index at 50 DAS of soybean over application of 20 kg P2O5 ha-1 and control but it was found at par with 40 kg P2O5 ha-1. The maximum seed yield (1942 kg ha-1) and straw (3305 kg ha-1) yield of soybean were recorded under application of 60 kg P2O5 ha-1 over application of 20 kg P2O5 ha-1 and control but it was found at par with 40 kg P2O5 ha-1. Significantly higher plant height at 60 DAS and at harvest, number of total root nodules plant-1, effective root nodules plant-1 and their dry weight at 45 DAS, chlorophyll content at 45 DAS, leaf area index at 50 DAS, seed yield (1870 kg ha-1) and straw yield (3179 kg ha-1) of soybean were recorded under application of 45 kg sulphur ha-1 which was found at par with 30 kg sulphur ha-1  and both these sulphur levels gave significant increase over application of 15 kg sulphur ha-1.

Background: To find out the suitable integrated nutrient management (INM) package for successful black gram production and to investigate the application of INM on growth, yield, quality and nutrient content of black gram (Vigna mungo L.). Methods: A field experiment was conducted during kharif season of 2019-20, the experiment was laid out in randomized block design with factorial concept having three factors viz,, three fertility levels (75%, 100% and 125% RDF), two FYM level (control and 5 ton FYM ha-1) and three biofertilizers level (Rhizobium, LMn16 and Rhizobium + LMn16) was applied to the variety MU-2 (Mukundra Urad 2). Result: The results indicated that application of higher fertility level like 125% RDF significantly increased all the yield parameters, nutrient content and uptake. Similarly, all the yield parameters, nutrient content and uptake significantly increased under application of FYM (5 ton ha-1) and bio fertilizer (Rhizobium + LMn16) over control plot and sole application of Rhizobium and LMn16 respectively.
