Nutrient management in pearlmillet (Pennisetum glaucum)–mustard (Brassica juncea) cropping system as affected by land configuration under limited irrigation
Abstract
A field experiment was conducted during kharif and rabi seasons of 2005–06 and 2006–07 at New Delhi on a sandy-loam soil to assess the effect of two land configurations, viz. Flat (F) and Ridge & Furrow (R&F) sowing and five nutrient management treatments (control, 30 + 8.8 kg N +P/ha (50% recommended dose of fertilizer i.e. RDF), 60 + 17.6 kg N +P/ha (RDF), 50% RDF + FYM (6 t/ha) and FYM alone to pearlmillet (Penisetum glaucum). Residual effects of pearlmillet treatments on mustard (Brassica juncea) were assessed at 50% RDF and RDF to mustard. Results revealed that R&F sowing and integrated nutrient management of 50% RDF + 6 t FYM to pearlmillet recorded higher yield of both pearlmillet and mustard over flat sowing and other fertility levels during both the years. Application of RDF to mustard improved the seed yield (1.31 t/ha) by 43.8 and 33.0% over control and 50% RDF. Ridge and furrow sowing and 50% RDF + FYM application recorded significantly higher N and P uptake by both the crops over flat sowing and other fertility levels, respectively.
