Abstract:
Studies conducted at the Agronomic Research Station, Chalakudy revealed
that the grain yield of blackgram grown in rice fallows during summer was significantly
influenced by water management practices. Irrigating the crop at an
IW/CPE of 0.5 was found to be the best. The ratios of 0.75 and 0.5 and bellshaped
irrigation recorded 105, 107 and 109 per cent increase in grain yield over no irrigation
control. It was also observed that both the varieties tried viz., T9 and Co 2
were on par in all the three seasons.
