A field experiment was conducted during two consecutive years from 2014-15 and 2015-16 at Agricultural Research Station, Kota, entitled “Effect of last irrigation scheduling and foliar spray of bio regulators the productivity of wheat (Triticum aestivum L.) in context to the changing climate under South East Rajasthan”. In this experiment, treatments comprised combinations of five irrigation schedule (early milk, late milk, early soft dough, late soft dough and IW/CPE 0.8 control) and three bio-regulators foliar spray at tillering and heading stage (thiosalicylic acid 100 ppm, thiourea 500 ppm and control) thereby making twelve treatment combinations were replicated four replications. Pooled data shows that under last irrigation at late milk stage was recorded significantly the highest grain yield (5.3 t/ha) and straw yield (7.0 t/ha) as compare to early milk, late soft dough stage and control but at par with early soft dough stage. Under the last irrigation at late milk stage were recorded significantly the highest net return (Rs.86.5 thousand/ ha) and B:C ratio (4.27) as compare to early milk, late soft dough stage and control but at par with early dough stage. The maximum grain yield (5.2 t/ha) and straw yield (7.0 t/ha), net returns (Rs.83.7 thousand/ ha) and benefit cost ratio (4.05) of wheat were recorded under foliar spray of thiosalicylic acid (100 ppm) in pooled analysis. Higher water use efficiency (157.20 kg/ha-cm) under last irrigation at late milk stage and (159.36 kg/ha-cm) foliar spray of thiosalicylic acid were observed over control.
