Performance of Two Fodder Pearl Millet Varieties under Different Seeding and Nitrogen Fertilizer Rates أداء صنفين من دخن العلف تحت تأثير معدلات التقاوى والتسميد النتروجينى

Abstract

Two field experiments were carried out at Sids Agric. Research Station, BeniSuef, Governorate, ARC, Egypt during the two successive summer seasons of the years 2016 and 2017 to study the effect of seeding rate (15, 20 and 25 kg/fed) and N-rates of nitrogen (60, 90 and 120 kg N/fed) on two variety of forage pearl millet (Shandweel 1 as a local variety and Saudian variety). ). Saudian variety (Pennsitium glaucum (L) R. Br. : Syn. Pennsitium americanium (L) Fam. Poaceae. This introduced variety was identified by the Flora and Phytotaxonomy Research Department, Agricultural Museum, Dokki, Giza, Egypt. The experiments were laid out in split plot design with three replications. Seeding rate at 25 kg/fed recorded the highest plant height with using the 3 rd N levels for the two varieties. More, the local variety surpassed Sau8dian variety. Saudian variety achieved the highest means of leaf stem ratio at 20 kg seeding rate/fed when plots treated with 120 kg N/fed. While, the highest mean of stem diameter recorded from Shandaweel 1 at the rate of 20 kg/fed and using 120 kg N/fed. In addition the rate of 20 kg/fed and 90 or 120 kg N/fed recorded the highest mean of fresh and dry yields or the two varieties. Finally, protein% recorded from Saudian variety at the rate of 20 kg/fed and 90 kg N/fed while, local variety recorded the highest mean for CF% and ash content at the same rate of seeding rate and nitrogen levels.
