摘 要：正 Zinc （Zn） is one of the essential micronutrients required for growth and development of crops. It plays an important role in different plant metabolism process like development of cell wall, respiration, photosynthesis and other bio-chemical functions etc. As much as around 40% of soil samples analyzed throughout all districts of West Bengal have been found to be deficient in Zn. The problem seems to be more acute for rice as around half of the total rice areas found
