Efficiency of Black Urea Fertilizer over White Urea



To reduce the loss of nitrogen and to improve cost effectiveness as well as plant nitrogen content, a humic acid coated urea fertilizer, called Black Urea is used in the present experiment. Four sets of pot experiment was conducted here to compare the efficiency of black urea fertilizer over conventional white urea. Kalmi, a fast growing, leafy vegetable, was allowed to grow for 60 days to carry out this experiment. After harvesting, both the root and shoot growth of the plants for all four sets of experiment and the available N and P content was calculated. In addition to that plant protein content was analyzed to draw the conclusion undoubtedly. Black urea was evidenced to posses better efficiency over white urea fertilizer as far as the nutritional quality and cost of the experiment was concerned.
