Role of micro-nutrients in cole crops: A review

Abstract

Cole crops belong to the species Brassica oleracea at a primary level and those managed right now: cauliflower, Brussels sprouts, sprouting broccoli, kohl rabi, kale and three types of cabbage, red, white and savoy. These crops are cultivated mostly in winter season. Proper environmental condition, soil condition and climatic condition are needed for their proper growth and development. Plant nutrient is one of the most important factors for getting better return from any crop. Application of micronutrients with macronutrients in proper amount and ratio in an integrated manner led the plant to proper growth and development. Macro nutrients help to improve development and yield of cole crops because of the role of nitrogen, phosphorus and potassium on the meristematic action. While, boron, zinc, copper, chlorine, manganese, iron and molybdenum are fundamental micronutrients required in minute quantities, for ordinary plant development and improvement as micronutrients helps in plant metabolism, chlorophyll synthesis, nutrient regulation, reproductive growth, flower retention, fruit and seed development. Lacking of boron, zinc, manganese and molybdenum are extremely common in cole crops which causes a number of anatomical, physiological and natural changes. Considering these, the present review focus on the importance and function of micronutrients in cole crops production and for better understanding also gives a brief overview of some recent findings related to role of micronutrients in cole crops
