Borlogue Crop Research Centre of G.B. Pant University of Agriculture and Technology, Pantnagar (290 N latitude and 790 29’ E longitude). Ten different treatments viz. T1-Control(No fertilizer), T2-50% Recommended Dose of Fertilizer (60:30:20)kg N,P2O5,K2O/ha, T3-75% Recommended Dose of Fertilizer(90:45:30)kg N,P2O5, K2O/ha, T4-100% Recommended Dose of Fertilizer(120:60:40)kg N,P2O5,K2O/ha, T5-50% Recommended Dose of Fertilizer+foliar spray @ 0.5% urea at tillering, panicle initiation and heading stage, T6-75% Recommended Dose of Fertilizer+foliar spray @0.5% urea at tillering, panicle initiation and heading stage, T7-100% Recommended Dose of Fertilizer+foliar spray @ 0.5%urea at tillering, panicle initiation and heading stage, T8-50% Recommended Dose of Fertilizer +foliar spray @ 1% urea at tillering, panicle initiation and heading stage, T9-75% Recommended Dose of Fertilizer+foliar spray @ 1% urea at tillering, panicle initiation and heading stage, T10- 100% Recommended Dose of Fertilizer+foliar spray @ 1% urea at tillering, panicle initiation and heading stage with three replications were laid out in randomized block design. Soil and crop parameters of rice were taken studied and analyzed to achieve the objectives of the experiment. In this experiment urea was used for foliar spray. The rate of urea applied was 2.3 kg/ha for 1% urea and 1.15 kg/ha for 0.5% urea at tillering, panicle initiation and heading stage. The result showed that soil and foliar application of nitrogen significantly influenced the growth and yield attributing characters viz. dry matter accumulation, no. of effective tillers per plant, no. of grains per panicle, 1000 grain weight, grain yield, straw yield. Plant height was found highest in T7. The treatment T10 produced the highest grain yield (5.4 t /ha).The treatment T7 produced the highest straw yield (6.9 t /ha) of the crop. The lowest grain yield of (2.95 t/ha) and lowest straw yield of (4.54 t /ha) were recorded in treatment T1 (control).The N, P, K concentrations of rice grain and straw influenced significantly by soil and foliar application of urea. Soil properties i.e. pH, EC and organic carbon status after harvest were found non-significant with different treatments. Available N, P and K status were 274 kg /ha, 24.1 kg /ha and 114 kg /ha before sowing and the maximum soil available nitrogen (294.2 kg /ha), phosphorus (31.1 kg /ha) and potassium (134.9 kg /ha) status after harvest was recorded with treatment T10.The agronomic efficiency and partial factor productivity was maximum in treatment T5. The overall results demonstrated that T10 treatment was better for obtaining higher grain yield, straw yield, higher NPK content of rice, soil nutrient status. Hence, soil application of recommended dose of urea can be replaced by soil application of urea coupled with three times foliar spray of urea solution for sustainable rice yield.enThesis
