Abstract :

The Effect of different levels of nitrogen (control, 50 and 100 kg/ha) and phosphorus (control, 50 and 100 kg/ha) on the growth and production of wild rye species studied. Nitrogen Application of 100 kg/ha height, number of leaves, tiller, stem and leaf dry weight, 30/7, 63/4, 103, 82, 131, and 33.3 percent increased respectively. In this study, the height, number of leaves and tillers, stem dry weight and leaf dry weight by 20 kg of nitrogen fertilizer significant increase in stem dry weight caused. crop height, leaf number, tiller number, leaf dry weight and shoot dry weight of wild rye by application of 40 kg/ha phosphorus additive, 13/1, 25/3, 38/4, 29/7 and 47/6 percent , respectively increased. Leaf Area index treated with 112 percent increase in the application of 40 kg P ha and 100 kg N ha respectively. Maximum biomass per unit of 430 gr/m2 by application 20 and 40 kg/ha phosphorus with 100 kg/ha nitrogen was obtained.
