Abstract


A field experiment was conducted at Gulbarga during kharif seasons of 2003 - 2005 to evaluate the effect of two pigeonpea varieties viz., ICPL-87119 (Asha) and ICP-8863 (Maruti)  and two intercrops viz., greengram cv. Chinamung and pearlmillet cv. ICTP-8203 in 1:2 row proportions. The pooled results indicated that intercropping of pigeonpea genotype ICPL-87119 (Asha) with greengram (15.11 q/ha) and pearlmillet (13.87 q ha-1) recorded significantly higher seed yield as compared to ICP-8863 (Maruti) genotype intercropped with greengram (13.69 q ha-1) and pearlmillet (12.56 q ha-1). The seed yield of greengram and pearlmillet were more when intercropped with Asha (3.24 and 5.46 q ha-1, respectively) genotype as compared to ICP-8863 (Maruti) (2.96 and 5.04 q ha-1, respectively). Among the cropping systems, pigeonpea ICPL-87119 (Asha) + greengram intercropping system with RDF + 2% urea spray at 15 and 30 Days after harvest of intercrops recorded significantly higher pigeonpea equivalent (19.53 and 18.99 q ha-1), gross returns (Rs. 31439 and 30576 ha-1), net returns (Rs. 23984 and 22928 ha-1) and B:C ratio (3.81 and 3.63) over other intercropping systems.
