Evaluation of Number of Irrigations on Hopper Management

Effect of different number of irrigations on hoppers showed that maximum hopper populations were recorded in nine irrigations where one irrigation each in October, December and February and two irrigations each from April to June were given, whereas hopper population were at par in five irrigations where two irrigations each in April and May and one irrigation in June were given, in two irrigations where one irrigation each in April and May were given and in control where no irrigation was done. The fruit set was significantly different in all treatments as compared to control whereas maximum fruit set (190.42 and 126.42 fruits/panicles) was recorded in five irrigations. Fruits harvested were maximum (108.57 fruits/100 panicles) in five irrigations that were significantly different from control. Weight of fruits per 100 panicles was maximum (18.80 kg) in five irrigations, which were at par with the two irrigations, and nine irrigations, however all these were significantly different from the control where minimum (16.38 kg/100 panicles) fruit weight was recorded.
