Abstract: A field experiment was conducted during rabi season of 2017-18 entitled “Effect of environmental factors on pod damage percentage by gram pod borer (Helicoverpa armigera)†in saline alkaline soil of Narendra Deva University of Agriculture & Technology, Narendra Nagar (Kumarganj), Ayodhya (U.P.). The experiment consisted in R.B.D. of three replication and nine treatment combinations comprised with three varieties and three date of sowing viz., sowing on Nov. 5th with temperature 23.8°C, Nov 15th with temperature 20.8°C and Nov. 25th with temperature 16.8°C and three varieties Uday (V1), Pusa-362 (V2) and Radhey (V3). The results revealed that higher pod damage was recorded with all varieties in crop sown at November 25th followed by November 15th sown crop While lowest pod damage percentage was recorded in crop sown at November 05th. The highest pod damage percent among all varieties was recorded in Radhey followed by Pusa-362, while lowest pod damage percentage was recorded in variety Uday at each date of sowing.
