Effect of integrated nutrient management on growth, yield, quality and nutrient uptake of Indian mustard (Brassica juncea) in arid zone of Rajasthan

A field experiment was conducted during the winter (rabi) seasons of 2009–10 and 2010–11 to study the effect of farmyard manure (FYM) and nutrients on growth, yield, quality and nutrient uptake of Indian mustard [Brassica juncea (L.) Czernj. & Cosson]. Treatments consisted of 3 levels each of FYM (0, 10 and 20 t FYM/ha) and nutrients (0, 40 kg N + 20 Kg P₂O₅ and 80 kg N + 40 Kg P₂O₅/ha) were evaluated thrice in a factorial randomized block design. The plant height, dry matter accumulation, primary and secondary branches/plant, chlorophyll content in fresh leaves, siliquae/plant, seeds/siliqua, 1,000-seed weight and seed and stover yields were significantly higher under incorporation of 20 t FYM/ha over 10 t FYM/ha. Plant height, dry matter accumulation, chlorophyll content, siliquae/plant, seeds/siliqua, 1,000-seed weight, seed and stover yield, nutrient uptake, oil content and oil yield increased significantly up to 80 kg N + 40 Kg P₂O₅/ha.
