Abstract:
Six sowing periods during kharif (3^rd week of July, 4^th week of July, 1^st week of August, 2^nd week of August, 3^rd week of August and 4^th week of August) was evaluated for its impact on incidence of stem fly, Melanagromyza sojae (Zehntner) infesting black gram at Entomology Farm, B. A. College of Agriculture, Anand Agricultural University, Anand. The black gram crop sown during 3^rd week of July exhibited low infestation (22.69%) and tunnelling (3.85%) followed by 4^th week of July during kharif. Crop sown early i.e., 3^rd and 4^th week of July registered low larval (0.11 and 0.16/plant, respectively) and pupal (0.16 and 0.19/plant, respectively) counts in comparison to crop sown during August. Maximum seed and haulm yield was harvested from the crop sown during 3^rd week of July (806 and 429 kg/ha) during kharif season.
