Response of some barley varieties to seeding rates and nitrogen fertilizer levels under rain-fed conditions in south jordan

This research was carried out during both growing seasons 2009/10 - 2010/11 at the National Center for Agricultural Research and Extension (NCARE) / Karak Governorate / Jordan, to study the response of five barley varieties namely Mu'tah, Yarmok, Athroh, Rum and Acsad-176 to the effect of four seeding rates (50, 100, 150 and 200kg/ha) and five nitrogen fertilizer levels (0, 15, 30, 45 and 60kg/ha) on the productivity of grain and straw, the harvest index and some phenological indicators.

Effect of Seeding Rates on The Productivity of Durum Wheat Genotypes in Three Diverse Locations

Twelve genotypes were tested for grain yield in three diverse locations seasons 2013-2014 and 2014-2015. The genetic material contained 7 promising lines and five checks representing the local and improved cultivars durum wheat for Zoon (A, B) in Syria.
