Effect of Cobalt, Boron and Molybdenum at Different Fertility Status on Vegetative Growth at Reproductive Stage of Pea (Pisum sativum L.)

摘要

A pot experiment was conducted during the winter season of 2006-07 and 2007-08 to study the effect of cobalt, boron and molybdenum on plant height, fresh weight and dry weight at reproductive stage of pea at two fertility status namely F sub(1) (30 mg P sub(2)O sub(5) + 20 mg S + 2.5 mg Zn, per kg soil) and F sub(2) (60 mg P sub(2)O sub(5) + 40 mg S + 5.0 mg Zn, per kg soil). The study reveals that plant height, fresh weight and dry weight of the plant at flowering and pod filling stage increased significantly with increasing levels of soil fertility in both the years. The macronutrients helped in better growth of root and shoot system enhancing the surface area of root and shoot for development of nodule and fruit setting. The micronutrients have shown significant impact on plant metabolism absorption and translocation of materials synthesis of essential macro and micro molecule and enzyme synthesis and their activity regulation.
