Abstract
A field experiment was conducted during 3 rainy seasons of 2000-2002 at Regional Agricultural Research Station, Bijapur, in medium black soil, to study the effect of fertilizer and biofertilizer on pearl millet [Pennisetum glaucum (L.) R. Br. emend. Stuntz] under sole and intercropping system. The grain yield of pearl millet was signifi- cantly higher under sole cropping (18.88 qlha) compared to intercropped pearl millet (16.69 qlha). However, pearl millet-equivalent yield, net returns and benefit : cost ratio were higher with pearl millet + pigeonpea [Cajanus cajan (L.) Millsp.] (2:l) intercropping system (47.38 qlha, Rs 113,988lha and 2.79 respectively) over sole crop of pearl millet (18.88 qlha, Rs 4,864lha and 2.25 respectively). Irrespective of cropping systems, appli- cation of 60 kg N + 40 kg P2051ha recorded significantly higher pearl millet-grain equivalent yield (36.17 qlha) over absolute control, seed treatment with biofertilizer alone and application of 20 kg N+15 kg P205/ha (28.30, 31.22 and 33.42 qlha respectively) but was on par with 40 kg N + 30 kg P20$ha + biofertilizer and recommended fertilizer dose (50 kg N + 25 kg P20$ha) of the region (35.41 and 33.71 @ha respectively). Net monetary returns were higher with application of 60 kg N + 40 kg P2051ha (Rs 10,144lha) and it was on a par with 40 kg N + 30 kg P20$ha + biofertilizer seed treatment (Rs 10,130ha).
