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

摘要

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 and 80 kg N + 40 Kg Pp/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 P_2O_5 /ha.
