Depth of nitrogen fertiliser placement affects nitrogen accumulation, translocation and nitrate-nitrogen content in soil of rainfed wheat
A field experiment was conducted to examine the effects of different depths ofnitrogen (N) fertiliser placements on N accumulation, remobilisation and NO3−-Ncontent in soil of rainfed wheat. Nitrogen was applied on the surface (D1) and inthe 10 cm (D2), 20 cm (D3) and 30 cm (D4) soil layers from 2010 to 2012.Compared with D1 and D2, D3 and D4 treatments obtained significant higher Ndistribution...
متن کاملAnalysis of nitrate reductase mRNA expression and nitrate reductase activity in response to nitrogen supply
Nitrate is one of the major sources of nitrogen for the growth of plants. It is taken up by plant roots and transported to the leaves where it is reduced to nitrite in the. The main objective of this research was to investigate stimulatory effects of sodium nitrate, potassium nitrate, ammonia and urea on the production/generation of the nitrate reductase mRNA in Triticum aestivum plants. The pl...
متن کاملSeasonal and Long-Term Changes in Nitrate-Nitrogen Content of Well Water in Oklahoma
To ensure that NO3-N concentrations in groundwater do not exceed the maximum contaminant level (MCL; 10 mg L-~), drinking water supplies are continuously sampled and analyzed. Water sampling and analytical methods have changed during the past 40 yr, and failure to apply the errors associated with those methods places researchers at risk of reporting invalid NO3-N changes. The objectives of this...
متن کاملIntervarietal Differences in Nitrogen Content and Nitrate Assimilation in Wheat (triticum Aestivum L.) under Salt Stress
Effect of five NaCl salinity treatments (0, 50, 100, 200 and 300 mM) given at different growth and developmental stages on total N level and in vitro nitrate reductase activity (NRA) in leaves and roots of two wheat cultivars viz., Ghods and Boolani was studied in greenhouse conditions. In response to salinity treatments, total N concentrations and NO3 assimilation rates in Ghods, a saltsensiti...
متن کاملCorn Yield and Nitrate Loss in Subsurface Drainage from Midseason Nitrogen Fertilizer Application
Whether in response to remotely sensed plant N status or as a rescue treatment when previously applied N has been lost to denitrification or leaching, there is growing interest in applying N to corn at midseason. While the yield benefits of this practice are variable, little information is available as to the impacts of midseason N application on water quality. We compared grain yields and NO3 ...
