Effect of foliar spray of micronutrients on yield and oil content of Indian mustard (Brassica juncea)

A field experiment was conducted during the winter season (rabi) of 1989-90 and 1990-91 to study the effect of Zn, B and Mo on the yield and quality of Indian mustard [Brassica juncea (L.) Czernj. & Cosson] in acid lateritic soil of Kharagpur. Application of Zn and B along with recommended NPK increased the seed yield respectively by 26 and 18% in the first year and by 49 and 47% in the second year over NPK alone. The increase in seed yield was associated with the increase in siliquae/plant, seeds/siliqua and 1,000-seed weight. Significant increase in the oil content was also noted by the application of both Zn and B.
