Experiment consisted of 10 treatments with three replications under RCBD. Results showed that, foliar applications of 1.0 per cent 19:19:19 at 40 and 60 DAS resulted in significantly higher seed yield (27.50 q ha-1) which was 23 per cent higher than the control (22.36 q ha-1) and was on par with urea spray (2.0 %) at 40 DAS plus KNO3 (1.0 %) at 60 DAS (27.08 q ha-1). All the foliar nutrition treatments were statistically superior to control except foliar spray only with urea (2.0 %), KNO3 (1.0 %) and 19:19:19 (0.5 %). The improvement in growth characters and yield contributing attributes contributed to the higher economic yield in the said treatments. The uptake of nutrients (N, P, K and S) in foliar applied treatments significantly increased over control due to 1.0 per cent spray of 19:19:19 at 40 and 60 DAS, urea (2.0 % at 40 DAS) plus KNO3 (1.0 % at 60 DAS) as well as their individual applications. There was significant improvement in protein content of seeds due to the said treatments. Highest B: C ratio (2.45) was recorded due to twice foliar application of 19:19:19 and lowest value (1.84) in control. Hence, foliar application of 19:19:19 (1.0 %) alone or combined application of urea (2.0 %) plus KNO3 (1.0 %) improved soybean productivity and protein content in soybean seeds.EnglishThesis
