Performance of pigeonpea based cropping systems under set furrow cultivation in vertisols

Abstract

Three field experiments were conducted at Agricultural Research Station, Gulbarga newlineon shallow and medium deep black soils during kharif 2005 and 2006 to evaluate newline Performance of pigeonpea based cropping systems under set-furrow cultivation in vertisols . newlineEvaluation of pigeonpea genotypes of different duration for different planting geometry was newlineconducted in medium deep black soil. Significantly higher seed yield was obtained with ICPL- newline87119 (15.99 q/ha) which was 8 per cent higher than ICP-8863 (15.00 q ha-1) and 20 per cent newlinehigher than WRP-1 (13.44 q/ha) and 48 per cent higher than GC-11-39 (10.68 q/ha). The newlinepigeonpea genotype ICPL-87119 sown at 120cm x 15cm recorded significantly higher net newlinereturns (Rs. 25,290/ha) and benefit cost ratio (2.69) when compared to ICPL-87119 sown at newline90 cm x 20 cm (Rs. 22,868/ha and 2.43, respectively). The genotype ICP-8863 sown at 120 newlinecm x 15 cm recorded a net return of Rs. 22,668 ha-1 and benefit cost ratio (2.40). The short newlineduration genotype GC-11-39 sown at 90 cm x 20 cm recorded a net return of Rs. 14,170/ha newlineand benefit cost ratio 1.69. Intercropped pigeonpea+sesame (1:2) system under set-furrow newlinewith application of vermicompost at 2.5 t/ha recorded significantly higher seed yield (15.58 newlineq/ha) and stalk yield (34.31 q/ha) as compared to flat bed method (12.96 q/ha and 28.76 q/ha, newlinerespectively). The intercropped pigeonpea+sesame (1:2) system under set-furrow recorded newlinesignificantly higher net returns (Rs 34,467/ha) and benefit cost ratio (2.91) over sole crop of newlinepigeonpea (Rs 17,407/ha and 1.85, respectively). Effect of set-furrow cultivation was studied newlinein pigeonpea+greengram intercropping system in medium deep black soil. Intercropped newlinepigeonpea+greengram (1:2) system under set-furrow with application of vermicompost at 2.5 newlinet/ha recorded significantly higher seed yield (16.85 q/ha) and stalk yield (36.57 q/ha) as newlinecompared to flat bed method (13.58 q/ha and 29.60 q/ha, respectively). The intercropped newlinepigeonpea+ greengram (1:2) system with set-furrow recorded significantly higher ne
