Assessment of Chickpea-Spices Intercropping Productivity Using Competitive Indices Under Irrigated Conditions of Haryana

摘要

Abstract A study was undertaken for using Umbelliferous spices, coriander, fenugreek and fennel as intercrop with chickpea in 2:1, 3:1 and 4:2 row ratios, each separately with their respective sole treatments during the winter season 2010–2011, to determine the effect of different intercropping systems on productivity and competitive functions. The yield of chickpea increased progressively with the increase in number of rows of chickpea in every intercropping system. All the intercropping systems produced higher land equivalent ratio (LER) than their respective sole cropping. Chickpea?and?fennel (4:2 row ratio) recorded higher benefit in terms of monetary advantage index (MAI) (Rs. 6990?ha?1), income equivalent ratio (IER) (2.03), system productivity index (SPI) or intercropping advantages (IA) among the all the intercropping systems. All the three spices performed as a dominant component, while chickpea was suppressed, and higher competition was noticed when coriander was taken as an intercrop, while competition was less in chickpea?and?fennel intercropping system.]]>
