| Abstract | ||
| Two field experiments were conducted at Ismailia Agricultural Research Station during two successive summer seasons of 2010 and 2011. The response of pearl millet cultivar (Shandaweel-1) grown under sandy soil conditions to different mineral N fertilization rates (60, 90 and 120 kg N fed-1) and foliar application of chelated-EDTA micronutrients (Fe + Mn + Zn) at rates of 0.0, 0.2, 0.4 and 0.6 g l-1 (400 l fed-1) on growth characters, productivity, and some nutrient contents, were appraised. Such response was followed up through three cuts; at 45, 85, and 125 days from complete emergence of the seedlings. The obtained results reveal that plant height, number of tillers per plant and productivity of pearl millet; fresh forage and dry matter yields of the three cuts at the both seasons, were enhanced by increasing the application rate of N fertilization. Foliar application of micronutrients markedly augmented such parameters. The best results were obtained when applying 120 kg N fed-1 accompanied with micronutrient foliar application of either 0.4 or 0. 6 g l-1. Carbohydrate, protein and crude fiber contents (%) of the dry matter of pearl millet plants were remarkably raised due to increasing rates of both; N fertilization and foliar micronutrients. Moreover, the uptake of N, P, K (kg fed-1) and uptake of Fe, Mn and Zn (g fed-1) by millet plants were elevated. Focusing on the necessity of growing pearl millet as a prosperous summer forage crop in Egypt was speculated. | ||
