Abstract :
A field experiment was conducted to study the effect of different levels of irrigation and nitrogen on growth and radiation use efficiency of wheat crop. The results exhibited that the Crop growth rate (g m-2d-1), Leaf area index, Leaf area Duration (days),Number of fertile tiller unit-1 area, Number of grains spike-1and Harvest index (%) were significantly increased by increasing the number of irrigation and nitrogen levels. Among irrigation levels, highest value (37.34) for harvest index was achieved in treatment I4 (irrigation at tillering + booting + anthesis + milking + dough) and the highest value for harvest index (36.35) was recorded for treatment N2 (150 kg N ha-1). This was formed the best combination for having maximum harvest index of the variety SH-2002.
