A field experiment was conducted during kharif 2015-16 at the research farm of All India Co-ordinated Research Project for Dryland Agriculture, GKVK, UAS, Bengaluru to study the effect of foliar application of different tolerance inducing nutrients onyield and rain water use efficiency of finger millet under rainfed situation. The experiment was conducted with 7 treatments viz., T_1: Foliar spray of water (Control), T_2: Foliar spray of Sodium selenite @ 10 g ha~(-1), T_3: Foliar spray of Sodium selenite @ 20 g ha~(-1), T_4: Foliar spray of 1 KNO_3, T_5: Foliar spray of 2 KNO_3, T_6: Foliar spray of thiourea (250 g ha~(-1)), T_7: Foliar spray of 1 KCl in Randomised Block Design with three replications. The results revealed that different foliarsprays influenced the growth and yield of finger millet. Application of 2 KNO_3 at panicle initiation stage and second spray 8 days after first spray resulted in higher grain yield (2637 kg ha~(-1)), straw yield (5139 kg ha~(-1)), rain water use efficiency (5.08 kg ha~(-1)mm~(-1)), net return (I.Rs 35493 ha~(-1)) and B:C ratio (2.35).
