A field experiment was conducted from 2015 to 2016 to determine the effect of foliar application of nutrients on growth, yield and economics of wheat (Triticum aestivum. L). The study was conducted at research farm of Advanced Centre for Rainfed Agriculture under AICRPDA, Rakhdhiansar, SKUAST-Jammu. Seven treatments viz: T1: Control (No spray), T2: Foliar spray of 0.5% K solution in water (KNO3), T3: T2 + Foliar spray of 0.5% N solution in water (Urea), T4: Foliar spray of 0.5% K solution in water (KCl), T5: T4 + Foliar spray of 0.5% N solution in water (Urea), T6: Foliar spray of 0.5% N solution in water (Urea), T7: Foliar spray of water were replicated thrice in a randomized complete block design (RCBD). The data of two years were pooled and statistically analyzed using analysis of variance (ANOVA) for Randomized Complete Block Design. The treatment means were tested for significance at P = 0.05. The results revealed that foliar application of nutrients resulted in significant effect on wheat grain and straw yield. Significantly higher wheat grain yield of 2224 kg ha-1 was obtained in combined foliar spray of 0.5% N (urea) + 0.5% K (KCl) and it was statistically at par with the combined foliar spray of 0.5% N (Urea) + K (KNO3) with grain yield of 2007kg ha-1. The lowest grain yield (944 kg ha-1) was found in control. Similar trend was observed in yield contributing plant attributes. Significantly highest uptake N, P and K was recorded with the combined foliar spray of 0.5% N (urea) + 0.5% K (KCl) followed by T3 and T6 which were statistically at par. The highest gross return and net returns of Rs49430 and Rs 29576ha-1, respectively were obtained in foliar spray of 0.5% N (urea) + 0.5% K (KCl) with highest benefit:cost ratio while the lowest gross return and net returns to the tune of Rs 23992 and Rs6087 ha-1 were recorded in unfertilized control. The highest agronomic use efficiency (AUE) and apparent recovery (ARE) of nitrogen and potassium were recorded in T5. The study concluded that foliar application of 0.5% N (urea) + 0.5% K (KCl) played complementary role in improving crop productivity of wheat grown in rainfed conditions.
