Comparative studies on number of irrigations, planting methods and nitrogen levels for wheat in north delta soils [electronic resource].

Includes references.

Two field experiments were carried out at the Experimental Farm of Sakha Agricultural Research Station, Agricultural . Research Center (ARC), Egypt during 2010/2011 and 2011/2012 seasons to study the effect of number of irrigations (one, two and three), planting methods (bed, drilling and broadcasting) and nitrogen levels (67%, 100% and 133% of recommended rate i.e. 75 Kg N/fed) as well as their interaction on yield and its components of wheat Sids .12 cultivar. Each location was performed in separate experiment; every experiment was layout in strip-split plot design with three replications: . The obtained results showed that wheat yield and its components were significantly affected all main factors (number of irrigations, planting methods and nitrogen levels) in both seasons. • The highest values of yield and its components were obtained by applying the treatment of three irrigations after Mohayah irrigation as compared with other irrigation treatments (one or two irrigations) in both seasons. • The highest value of all studied characters were resulted from planting wheat by using broadcasting and bed methods as compared with drilling method in both seasons.
