Abstract

A pronounced residual effect of organic and inorganic nutrients, applied in pearl millet crop was observed on yields of pearl millet [Pennisetum glaucum (L.) R Br]-gobhi sarson (Brassica napus L. var napus) cropping system. The experiment was conducted (by way of inorganic and organic sources combinations) with 8 treatments of FYM, vermicompost, inorganic N and control. The highest growth, yield and yield parameters of pearl millet crop were recorded with 100% recommended fertilizer dose-RFD and the grain yield (2899 kg/ha) was about 85.2% higher over the control and was followed by statistically similar treatment 75% N inorganic + 25% VC with the grain yield value of 2703 kg/ha. In case of gobhi sarson, the highest grain yield (855 kg/ha) was observed owing to residual effect of 100% N through vermicompost (VC) applied in preceding pearl millet crop, which was about 82.3% higher over the control. The treatments where 50% N was substituted by FYM and VC in pearl millet crop had the statistically similar grain yield values of gobhi sarson. The highest rain water use efficiency (RWUE) and heat-use efficiency (HUE) was recorded in treatment 100% RFD in pearl millet crop and 100% N through VC in gobhi sarson.
