Effects of irrigation and nitrogen on growth, light interception and efficiency of light conversion in wheat

Effects of three irrigation treatments (rainfed, and irrigation at 7-day and 14-day frequencies beginning in spring) and two rates of nitrogen (0 and 150 kg N ha−1) on growth, light absorption, and conversion efficiency in wheat were studied. Growth was considered in four phases extending from 95 days after sowing (das 95) to the beginning of rapid stem growth (das 120), the stem growth-phase lasting to the onset of rapid grain-filling (das...
