Abstract:
A field experiment was carried out during kharif season of 2016-17 and 2017-18 at Mahatma Gandhi Chitrakoot Gramodaya Vishwavidyalaya, Chitrakoot, Satna (M.P.) to assess the effect of row ratio and nutrient management practices on growth parameters, yield and productivity of maize and pigeonpea under intercropping system. Growth parameters viz. plant height and dry weight/plant at 25 DAS of maize and plant height, trifoliate leaves at 60 DAS and primary and secondary branches of pigeonpea were observed statistically at par but markedly higher under 2:2 row ratio of maize + pigeonpea intercropping system during 2016-17 and 2017-18. However, dry weight/plant of pigeonpea and grain yield of maize and pigeonpea were obtained significantly greater under 2:2 row ratio of maize + pigeonpea system. LER and maize equivalent grain yield (CEY) was also estimated significantly superior under maize + pigeonpea (2:2 paired) system during two years. Maize + pigeonpea (2:2) system gave 659 kg (10.87%) and 765 kg (12%) more crop equivalent grain yield (CEY) over 1:1 row ratio of same system during two respective years.

Application of 75% RDF to main crop + FYM @ 5 t/ha recorded significantly greater growth parameters of maize viz. plant height and dry weight/plant at 25 DAS and pigeonpea i.e. plant height, dry weight/plant, trifoliate leaves, primary and secondary branches which exhibited statistically at par to 100% RDF to main crop. LER and CEY were obtained significantly higher under 75% RDF to main crop + FYM @ 5 t/ha and statistically on par to 100% RDF to main crop except LER in 2017-18. CEY was noted higher under 75% RDF to main crop + FYM 5 t/ha to tune of 338 kg (4.48%) and 364 kg (4.82%) over 100% RDF to main crop respectively during consecutive years. Grain yield of intercrop pigeonpea was significantly reduced compared to pure pigeonpea (1210 and 1299 kg/ha) which showed almost same under 75% RDF + FYM 5 t/ha to main crop (1305 and 1394 kh/ha) during two years.
