Effect of date of sowing on shoot webber and pod borer incidence and yield of sesame (Sesamum indicum Linn.).
Studies were conducted during the rainy season of 1990-94 to determine the effect of sowing time on the incidence of shoot webber and capsule borer (Antigastra catalaunalis) and the yield of sesame varieties. Results revealed that sowing on 23rd July recorded the lowest amount of damage, i.e., 6.7, 14.3 and 8.3% in leaves, flowers and pods, respectively, and produced a significantly higher yield i.e., 1239 kg ha-1. However, sowing on later dates (30th July, 6th and 13th August) resulted in a significantly higher level of damage to leaves, flowers and pods and a poor yield. However, pest incidence and crop yield was similar on each variety.
