SPACING, FERTILIZER AND FOLIAR SPRAY INFLUENCE ON YIELD ATTRIBUTING CHARACTERS OF TEPHROSIA (TEPHROSIA PURPUREA. L)K. Sivasubramaniam, S. Ambika and M. Vetrivel
A field experiment was conducted on Tephrosia (Tephrosia purpurea. L) seed crop to enhance seed yield with three NPK fertilizers levels [25:50:0 (B1), 25:50:5 (B2) and 25:50:10 (B3) NPK kgha-1] and three different spacing [30×15 (S1), 30×20 (S2) and 25×25 cm(S3) ) along with three foliar spray schedule of Pulse Booster TM (2.25 kg/ac) at 50 % flowering (F2) and 10 days after the first dose (F3) along with control (F1). Chlorophyll content, crop growth rate, relative growth rate, 100 seed weight (g), pod weight (kg plot-1), seed yield (g plot-1) and seed yield (kg ha-1) were higher in plants fertilized with 25:50:10 kg NPK ha-1 at 30x20 cm2 spacing and nourished with Pulse Booster foliar spray at 50 % flowering and followed by a second dose after 10 days.
