Abstract

Abstract The influence of four irrigation intensities (0.6, 0.8, 1.0 and 1.2 pan evaporation coefficients (p.e.c), three levels of nitrogenous fertilizers (40, 80 and 120 kg/ha) and spraying with endosulfan on the incidence of Heliothis armigera attack and the yield of tomato fruit (Variety: HS101) were investigated. The application of higher rates of nitrogen (120kg N/ha) and more irrigation (1.2 p.e.c.) resulted in significantly lower incidence of borer. This was attributed to higher total and marketable fruit yields under such inputs. Spraying with endosulfan (0.07%) resulted in a higher percentage of marketable produce, though total yields were similar at a given nitrogen and irrigation level. Keywords: Tomato fruit borerHeliothis armigera (Hubner)crop management practicesp.e.c.endosulfan
