Flower drop leading to poor pod-setting has been observed at some locations in Nepal. Experiments were carried out at Rampur in 1990/91 and 1991/92 to determine the causes (Botrytis gray mold (BGM) and soil factors) of poor pod-setting. In 1991 a significant increase in pods per plant and seed yield was obtained following spraying with the fungicide Bavistin. The fungicide spraying x genotype interaction was significant. The increase in yield was higher in susceptible varieties than in the resistant cultivar Dhanush. Both BGM and soil factors (low pH and associated nutritional problems) were responsible for the poor pod-setting of chickpeas grown at Rampur. Cultivar Dhanush, had field tolerance to BGM. Delayed sowing suppressed BGM incidence. But the varieties released were not suitable for late sowing
