Effect of dates of sowing and intercropping on pod damage caused by H. armigera in chickpea

Abstract

A field experiment was conducted during Rabi season of 2011-12 and 2012-13 at instructional farm, Junagadh Agricultural University, Junagadh to find effect of date of sowing and intercropping on pod damage caused by Helicoverpa armigera (Hubner) in chickpea. Results showed that the incidence of H. armigera on crop was found least per cent pod damage (17.47%) with the highest grain yield (793 kg ha-1) sown on 15th November as compare to other date of sowing (1st November and 30th November). Coriander (2:1) was taken as intercrop with chickpea, it found lower per cent pod damage (13.73%), which also recorded the highest equivalent yield (831 kg ha-1). Whereas, the chickpea sown on 15th of November and intercropped with coriander also registered the highest equivalent yield (947 kg ha-1) with lower per cent pod damage (10.96%).
