Response of pearl millet to form and level of fertilizers under irrigation

Abstract:

The objective of the trial was to determine the suitable fertilizer form and the optimum dose for pearl millet (cultivar Ashana) under irrigation. Four forms of ferilizer and five levels of each fertilizer form were assigned in a complete factorial experiment laid out in a randomized complete block design with three replications. The forms were urea (46%N), nitrophosca (18:18:5), ammonium sulphate nitrate (26%N) and ammonium sulphate (21% N), while the levels of each fertilizer form were 0N, 0.5N, 1N, 1.5N, and 2N. The experiment was carried-out at the Gezira Research Farm during 2004 and 2005. The parameters studied were: Days to 50% flowering, plant height, panicle length, panicle grain weight, grain number per panicle and per unit area, number of productive tillers, 1000 grain weight, nitrogen utilization efficiency, grain yield and threshing ability. The study showed that the form of fertilizer had no significant effect on all the variables studied, while variables like grain number per unit area, number of productive tillers and nitrogen utilization efficiency were significantly affected by levels of each fertilizer form. This in turn had resulted in a significantly more grain yield with added fertilizer levels. The study recommended that pearl millet (cultivar Ashana) could be fertilzed under irrigation by any of the mentioned four forms at a level of 1N of each form. This is equivalent to kg/fed of: 40 kg urea, 100 kg nitrophosca, 70 kg ammonium sulphate nitrate and 86 kg ammonium sulphate.
