| dc.description.abstract | A field experiment was conducted during Kharif, 2020 at Norman E. Borlaug Crop Research Centre of Govind Ballabh Pant University of Agriculture and Technology, Pantnagar to study the effect of two varieties (PS 1347 and SL 958) of soybean and the foliar spray (control, water spray, thiourea application at 250, 500 and 750 ppm) on growth, yield attributes, yield, quality (protein and oil), nutrient uptake (N, P, K and S) and economics of production. The test crop was sown on 25th June 2020 and harvested on 7th November 2020. The soil of the experimental field was Silty clay loam having organic matter (0.96 %), available nitrogen (233 kg/ha), available phosphorus (22.5 kg/ha), available potassium (140 kg/ha) and available Sulphur (20.5 kg/ha). The experiment was laid out in factorial randomized block design with four replications to evaluate two factors with ten treatments formed by the combination. The result obtained during the course of experimentation revealed that although varieties were statistically invariable in terms of plant height, PS 1347 recorded higher dry weight per plant at 45, 60, 75 DAS and at harvest. In terms of crop growth rate between different intervals PS 1347 recorded higher CGR (13.23 g/m2/day) than that of SL 958 (11.75 g/m2/day). Variety PS 1347 had a greater number of branches, number of pods per plant, seed index, seed yield, haulm yield, total biological yield, nutrient uptake and thus recorded higher gross return, net return and B:C ratio than SL 958. Application of thiourea improved the growth parameters, yield attributes, yield, nutrient uptake and profitability of the soybean crop. Among all the foliar sprays, lowest values were recorded in control and water sprays. Application of thiourea improved the crop growth, yield, nutrient uptake and profitability (gross return, net return and B:C) of the crop. But it could not influence plant height and dry weight at 30 DAS, RGR and CGR at all the growth intervals except between 30-45 DAS, protein content, oil content, nutrient (N, P and K) content and available nutrient in soil. Maximum improvements were recorded under the influence of thiourea spray at the concentration of 750 ppm, which was statistically at par with the values of parameters recorded at 500 ppm and these two were superior over control, water spray and thiourea concentration @ 250 ppm. Thus, it was concluded that the PS 1347 performed better than SL 958 and foliar spray of thiourea at the concentration of 500 and 750 ppm performed equally better. The interaction effect between the two factors were non-significant. | en_US |
