during the Rabi Season 2013-14 to study the effects of different planting dates and mechanical support for the management of insect pests in tomato. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications consisted of nine treatments. Significant variations were found among the treatment. At early fruiting stage of tomato in number and weight basis, the highest percentage of infested fruit (10.65% and 10.99%) was recorded in T7 treatment, while the lowest (2.67% and 4.35%) in T5 treatment. At mid fruiting stage of tomato in number and weight basis, the highest percentage of infested fruit (11.92% and 12.62%) was recorded in T7 treatment, while the lowest (3.13% and 4.50%) in T5 treatment. At late fruiting stage of tomato in number and weight basis, the highest percentage of infested fruit (10.15% and 10.66%) was recorded in T7 treatment, whereas the lowest (2.22% and 4.21%) in T5 treatment. At total fruiting stage of tomato in number and weight basis, the highest percentage of infested fruit (10.93% and 11.43%) was recorded in T7 treatment, whereas the lowest (2.66% and 4.35%) in T5 treatment. The highest fruit yield (55.91 t ha-1) was recorded in T5, whereas the lowest yield (45.39 t ha-1) in T7 treatment. Planting at 10 December with the method of Horizontal mechanical support was more effective for reduction of insect pest of tomato and also for highest yield.
