Effect of Nitrogen Fertilizer and Cutting Treatments on Forage and Its Components of Pearl Millet (Pennisetum glaucum L.) in Sulaimani Region

Abstract

This investigation was conducted for two successive years (2009 and 2010) in the Qliassan
 Agriculture Research Station, Faculty of Agricultural Sciences University of Sulaimani, to study the
 effect of Nitrogen fertilizer (0 , 20 , and 40 kg N/ha) and two cutting treatment (Clipping the crop
 once and twice) on the characters of plant height, number of tillers/ plant, fresh and dry leaf %,
 fresh and dry stem %, dry matter% , green and dry weight/plant, leaf dry weight , stem dry weight,
 and fresh and dry forage yield for pearl millet. Results indicated the presence of significant effect of
 nitrogen fertilizer on dry leaf% at the first season, and on plant height and number of tillers/plant
 at the second season and average of both seasons, and also on characters fresh weight/plant, and
 dry/weight/plant dry leaf yield, forage yield at the second season and dry leaf yield and fresh forage
 yield only for the average of both seasons. Concerning cutting treatments on studied characters for
 both seasons and average of two seasons, results indicated the out-yielding the treatment of two cut
 in plant height, fresh and dry steam% dry steam yield fresh forage yield , dry forage yield. While
 the treatment of one cut out-yielded two cuts in fresh and dry leaf% in which there are no
 significant effect of cutting on dry matter%, dry leaf yield. Concerning to the interaction effect
 between the two factor levels, the results of combine analysis indicate non significant effect on all
 characters except of plant height, fresh weight/plant in the average of both seasons, and dry leaf
 yield in the second season.
