Effect of Manure Application on Reduced Nitrogen Fertilizer Consumptionin Potato Cv.Agria
Objective: An experiment was performed in Ardabil (2012) to investigate the effects of manure consumption in different amounts on reducing nitrogen fertilizer consumption in potato cv. Agria. Methods: This research was conducted in factorial design based on randomized completely blocks design in three replication in which two manure factors in three levels (control, 30 and 60 tons/h) and nitro...

متن کاملEffect of Fertilizer and Irrigation on Nitrate-Nitrogen and Total Nitrogen in Potato Tubers'
This study was conducted to determine the effect of N fertilizer and irrigation management on potato (Sotanum tuberosum L,) tuber N0,-N levels and the relationship to the potential health hazard created by high nitrate levels in food products. `Russet Burbank' potatoes grown using different N fertilizer rates, methods of application, and irrigation levels were analyzed for N0,-N concentration. ...
متن کاملEffect of cover crops and application of nitrogen fertilizer on tuber yield and nitrogen use efficiency of potato (Solanum tuberosum L. cv. Sante)
Inclusion of cover crops in crop rotations has several benefits such as supplying nitrogen for the next crop. To investigate the effect of cover crops and different levels of nitrogen fertilizer on tuber yield, yield components, and different nitrogen efficiency indices of potato, a filed experiment was conducted as split plots arrangements in randomized complete block design with three replica...
متن کاملEffects of Fertilizer Nitrogen on Tree Growth, Foliar Nitrogen, and Herbage in Eastern Cottonwood Plantations I
When five rates of nitrogen fertilizer (0 to 672 kg! ha) were tested in two eastern cottonwood (Populus deltoides Bartr. ) plantations 7 and 10 years old in the Mississippi River floodplain , first season volume growth was more than doubled by fertilization . By the end of the third season, the direct effect of fertilization had apparently disappeared although a volume advantage caused by the l...
