Abstract

A quadreplicated split plot design field experiment with two main plot treatments and weight subplot treatments were conducted during summer 2011. Both the SH compounds and water was sprayed twice i.e., 25 and 45 DAS. Seed yield was not influenced but stover yield was significantly reduced due to moisture stress at vegetative stage (M2). Moisture stress did not influence protein content and protein yield. Crop without moisture stress (M1) produced higher net return and cost benefit ratio (CBR). Use of Thiourea 500 ppm (S4) increased seed and stover yield by 58 and 84% respectively over control (S1). Protein content and yield also increased with thiourea application @ 500 ppm (S4) over the SH compounds. Net return and CBR was highest with Thiourea 500 ppm. Use of thiourea @ 500 ppm without moisture stress earned maximum while moisture stress with control recorded the lowest net return and CBR. Foliar spray of thiourea@ 500 ppm twice at 25 and 45 DAS proved most effective to get higher yield and net return from summer greengram.
