Abstract:
A field experiment was conducted during rabi season of 2016-17 and 2017-18 at Mahatma Gandhi Chitrakoot Gramadaya Vishwavidyalaya, Chitrakoot, Satna (M.P.) to study the effect of row ratio and nutrient management practices on growth and yield of chickpea and mustard under intercropping system. Growth characters of chickpea viz. plant height, dry weight/plant at 60 DAS were observed numerically higher under chickpea + mustard (4:1) while, growth characters of mustard i.e. plant height, leaves/plant, dry weight at flower initiation and at harvest were markedly higher under chickpea + mustard (6:1) during two years. The grain yield (1500 and 1686 kg/ha) and straw yield (2696 and 2750 kg/ha) of chickpea were significantly higher in 6:1 row ratio during two years. While, intercrop mustard seed (625 and 668 kg/ha) and stover yield (2218 and 2444 kg/ha) was conspicuously higher under chickpea + mustard (4:1) system. In nutrient management, dry weight/plant of chickpea was found higher in 100% N equivalent from OM while, dry weight of mustard was noted significantly more in 125% RDF to main crop followed by FYM 10 t/ha + 75% RDF during two consecutive years. Application of FYM 10 t/ha + 75% RDF to main crop produced higher grain yield of chickpea while, straw yield was found more in 125% RDF to main crop. Mustard seed and straw yield was obtained markedly higher in 100% N equivalent to main crop from OM. Sole chickpea or sole mustard recorded higher dry weight of chickpea and mustard compared to treatment means, respectively. Pure and intercrop chickpea seed and straw yield was statistically at par during two years but it was decreased grain yield to the tune of 179.8 and 110.87 kg/ha over pure chickpea during two respective years. Significant highest chickpea equivalent grain yield (1827 and 2021 kg/ha) and LER (1.21 and 1.31) was recorded under 6:1 row ratio. In nutrient management, the highest chickpea equivalent grain yield (1866 and 2016 kg/ha) and LER (1.23 and 1.30) were obtained under FYM @ 10 t/ha + 75% RDF. Chickpea equivalent grain yield and LER were found markedly higher in intercrop than either sole chickpea or sole mustard.
