Effect of Different Amounts of Nitrogen Fertilizer on Grain Yield of Forage Corn Cultivars in Isfahan
To evaluate the effect of nitrogen fertilizer amounts on grain yield of forage corn in 2012, a pilot was implemented in Islamic Azad University Agricultural Research Station, Isfahan, as a split plot in a randomized complete block design. Main plots consisted of four levels: control (no fertilization ) , 50 , 100 and 150 kg per ha nitrogen from urea source and subplots , including several varie...

15 صفحه اولEffect of Different Amounts of Protein and Varying Proportions of Corn Silage and Alfalfa Hay on Milk Production and Nitrogen Excretion of Dairy Holstein Cows
Four treatments were assigned to determine the effects of dietary potential digestible fiber (pdF) and crude protein (CP) levels in mid lactating Holstein cows on milk production and nitrogen efficiency. Sixteen primiparous (n=8) and multiparous (n=8) Holstein cows (body weight (BW)=546±72 kg; days in milk (DIM)=118±50 day) were allocated to one of four diets in balanced randomized complete des...
