Abstract:
The present investigation was conducted to study on the influence of sowing date and mulches on the incidence of jassid in okra ecosystem during rabi hot weather season of 2016-2017 at Agronomy farm, College of Agriculture, Dapoli. The results indicated that the data on effect of different sowing dates on mean jassid population during 4^th, 5^th, 6^th, 7^th, 8^th and 9^thWeek after sowing (WAS), was minimum (2.12, 3.44, 6.55, 4.22, 2.21 and 0.96, respectively) in treatment S₁ (46^th SMW, 12^th-18^th Nov.) and was at par with S₂.

The data on effect of different mulches on mean jassid population during 4^th, 5^th, 6^th, 7^th and 8^th WAS, was minimum (0.02, 4.58, 7.29, 4.76 and 3.04, respectively) in treatment M₂ (Silver polythene mulch) which was at par with M₃.

The data on combination effect of different sowing dates and mulches on mean jassid population during 4^th,5^th, 6^th, 7^th, 8^th and 9^th WAS, was minimum (1.05) in treatment combinations S₁M₂ [S₁ (46^th SMW, 12^th-18^th Nov.) + M₂ (Silver polythene mulch)] and S₂M₂ [S₂ (49^th SMW, 3^rd-9^th Dec.) + M₂ (Silver polythene mulch)].
