گزارش نهایی بررسی واریته گندم دیم و مصرف کودهای شیمیایی

‭In order to consider charactristics of rainfed wheat reguarding the usage of Nitrogen and Posphourse fertilIzers. a randomIzed blocks experiment with four replicates in three levels of 0.15 and 30 kg/ha puore Nitrogen and posphourse with two kinds of treated wheats seeds "Azar and Rashid" and one kind of local wheats seeds was Carried out In ideal conditIon at Badranlo In Bojnord and Najaf- Abad in Ghochan The mean production were 700 kg/ha in Badranlo and 400 kg/ha In Najaf Abad. The Soil texture where the experiment was carried out was semi‬ی ‭deep. Silty loam and silty clay loam with alkaline action with a slope of 8% - 10%. Summary of results durIng four years of exprriment: 1- In Badranlo region reaction of both treated and local wheat seeds to N were positive and to P were higher. 2- In Najaf - Abad region reaction of treated wheat seeds were positive to N and P local wheat seeds response tp P were higher so that up to 15kg to N positive and higher than that - ve. Finally Azar variety with the N30 P30 fertilizer with 1293. 8kg/ha In Badranlo and 984.8kg/ha in Najaf - Abad had the highest productlon level.‬
