Title : EFFECT OF INTER AND BORDER CROPS ON THE Helicoverpa armigera (HUBNER) INCIDENCE AND YIELD IN CHICKPEA

Abstract :

The field experiment conducted during Rabi 2020-21(November 2020 to April 2021) to check the chickpea pod borer infestation in response to various inter and border crops at the research farm of Advanced Centre for Rainfed Agriculture (ACRA), Dhiansar, SKUAST-Jammu. The results revealed significantly lowest population of H. armigera in chickpea + linseed (intercrop) + napier (border crop) (0.27 to 4.67 larvae per meter row length) during 9th to 14th standard week respectively, followed by chickpea + linseed (intercrop) + mustard border crop) compare to sole chickpea. Where lowest pod damage per cent was recorded in chickpea + linseed (intercrop) + napier (border crop) with 11.84 per cent, followed by chickpea + linseed (intercrop) + mustard (border crop) and chickpea + coriander (intercrop) + napier (border crop) with 13.30 and 16.06 per cent damage, respectively. The study concluded that the highest chickpea yield and equivalent yield was calculated in T7 - Chickpea + linseed (intercrop) + mustard (border crop) 539.6 kg/ha and 1311.66 kg/ha respectively, with the highest B:C ratio of 1:5.47.
