Abstract
A field experiment was conducted at New Delhi during 1995-99 to study the effect of fertilizers including biofertilizers and stover management practices on productivity and soil fertility in chickpea (Cicer arietinum L.)-maize (Zea mays L.) cropping system. The results indicated that the yield of chickpea remained unaffected by fertilizer treatments. The yield of maize increased significantly with 100% recommended dose of fertilizer (120, 60,40 and 5 kg/ha ofN, P 2 O 5 , K 2 O and Zn) over the control (no fertilizer) and biofertilizers. The total productivity in terms of chickpea equivalent yield was the highest with 100% recommended dose of fertilizer to both the crops (3.27 tonnes/ha). Maize stover incorporation recorded markedly higher chickpea yield over chickpea stover and no stover incorporation. Application of stover of both crops or ofeither ofthe crops being on par recorded higher chickpea equivalent yield (3.10 tonnes/ha) over no stover incorporation. Stover application, however, had greater impact on chickpea equivalent yield when no fertilizers were applied. Maize stover incorporation recorded the highest chickpea equivalent yield (3.46 tonnes/ha) when maize received 100% recommended dose of fertilizer. The organic carbon content of soil increased with 100% recommended dose offertilizer and incorporation of stover of both the crops.
