Effect of Different Methods of Urea Application on Growth and Yield in Potato

M. Raihanul Islam Chowdhury, A. K. M. Golam Sarwar and A. M. Farooque    

Abstract: An experiment was conducted to find out the proper methods of urea application for maximizing the production of potato. All the studied parameters (Days required to 80% emergence, plant height, foliage coverage (%) per hill, number of stem per hill, fresh weight and dry weight of haulm, dry weight (%) of tuber, number of tuber per hill, yield of tuber per hill and yield of tuber per plot) were differed significantly (P<0.01) among the methods of urea application. Application of urea as 50 % basal + 50% top dressing produced the best result among the methods and it was found to be the most cost effective (1.99). It might be concluded that split application of urea (50% basal + 50% top dressing in two installment at 30 and 50 DAP) is the effective way to avoid the detrimental effect of urea on plant emergence and to maximize the tuber yield in Bangladesh.
