Abstract

Investigations were carried out to evaluate the yield losses caused byH elicoverpa armigera (Hubner) infesting chickpea at Junagadh Agricultural University campus, Junagadh during rabi season of 2008–09. The results revealed that there was significant reduction in larval population of H. armigera in protected plots as compared to unprotected plots after spraying of effective insecticides, which ultimately increased 69.98 per cent in grain yield (683 kg/ha) in protected plots. 41.17 per cent loss in grain yield could be avoided by giving proper protection against H. armigera on chickpea.
