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.
