Effect 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 کاملthe effect of plant density and various levels of nitrogen on protein percent, yield and nitrate accumulation in potato tuber
in order to evaluate plant density and different nitrogen levels on protein percent, yield and nitrate accumulation in potato tuber cv. agria, a factorial experiment based on randomized complete block design with three replications was conducted in ardabil in 2006. factors included nitrogen levels: 0, 80, 160 and 200 kg ha-1 net nitrogen and plant densities: 5.5, 7.5 and 11 plant m-2. results s...
متن کاملEffect of Plant Density and Nitrogen Fertilizer on Some Attribute Ofgrain Sorghum (Sorghum Bicolor (L.) Moench)
A field experiment was conducted in 2010, to evaluate the effects of plant density (D1, D2 and D3: 8, 14 and 20 plant/m2) on field performance of Sorghum under different nitrogen application rates (N1, N2 and N3: application of 40, 80 and 120 kg/ha Nitrogen, respectively). The experiment was arranged as factorial based...
متن کاملDetermining Nitrogen Fertilizer Needs for Sugarbeets from Residual Soil Nitrate and Mineralizable Nitrogen' J
Soil nitrate and mineralizable nitrogen are used to predict the root yield potential and N fertilizer needs of sugarbeets. Predicting the required N fertilizer for optimum refined sucrose production based on soil test procedures is needed because inadequate N limits root yield and high levels of N may reduce both extractable sucrose and sucrose yield. Sugarbeets (Beta vulgaris L.) were grown at...
