Effect of Nitrogen Application Amounts on Uptake and Utilization of Potassium in Cotton Grown in Improved Coastal Saline Land Regions Characterization of Nitrogen Uptake and Utilization in Rice under Different Planting Methods Effects of nitrogen application rate on soil inorganic nitrogen distribution,microbial biomass nitrogen content and yield of wheat Differences and Correlations in Grain Yield, N Uptake and Utilization Between Medium-Maturing Indica and Japonica Rice under Different N Fertilizer Levels Effects of reduced nitrogen application on nitrogen uptake and utilization efficiency in maize-soybean relay strip intercropping system Effects of nitrogen application on nitrogen absorption,utilization in super-high-yielding wheat in Huaibei region Effects of nitrogen fertilization on uptake and utilization of NPK and yield and quality of hybrid cotton Effects of sugar alcohols and amino acids on growth, quality and calcium nutrition of Chinese cabbage Phytate-phosphorus uptake and utilization by transgenic tobacco carrying Bacillus subtilis phytase gene Effects of planting density on uptake and utilization of N, P and Kof transgenic cotton Effect of row spacing on nitrogen uptake, nitrogen utilization and yield of summer maize Effect of inoculation of AMF on plant growth and phosphorus utilization in intercropped maize under chamber phosphorus addition on red soils in Dianchi Watershed DIFFERENCE OF NITROGEN UPTAKE AND UTILIZATION IN WHEAT CULTIVARS  WITH DIFFERENT GRAIN YIELD LEVEL Effects of nitrogen application rate on the nitrogen uptake and utilization of cotton grown in coastal saline fields of Yangtze River Valley Effects of nitrogen application rates on nitrogen uptake and utilization of direct-seeded cotton after wheat harvest. General Characteristics of Nitrogen Uptake and Utilization in Conventional Indica Rice Cultivars with Different Panicle Weight Types Effects of straw and straw biochar on wheat nutrient uptake and enzyme activity in brown soil Effects of Different Nitrogen Rates of Fertilization on Nitrogen, Phosphorous and Potassium Uptakes and Utilizations as well as Kernel Yield of Wheat under High-yield Circumstances Effects of Different Amount of Straw Incorporation on Grain Yield, Nitrogen Uptake and Use Efficiency in Wheat-rice Rotation System
