摘要：

A field experiment was conducted at Agronomy Research Area of Chaudhary Charan Singh Haryana Agricultural University, Hisar (India) during the rabi (winter) season of 2004-05 on a sandy loam soil to study the effect of nitrogen and seed rate on uptake and recovery of nitrogen by wheat varieties. The experiment consisting of combination of two varieties (WH-711 and HD-2687) and three seed rates (100, 90 and 80 kg/ha) as main plot treatments and three nitrogen levels as sub-plot treatments. The field experiment was laid out in split plot design with three replications. The results revealed that the varieties and the seed rates showed significant effect on nitrogen uptake and recovery. The variety WH-711 is more capable of nitrogen uptake and recovery than the variety HD-2687. Seed rate at 80% of the recommended rate (80 kg/ha) showed more nitrogen uptake and recovery than the seed rates at 100 and 90% of the recommended seed rates (100 and 90 kg/ha). However, nitrogen levels have not caused any significant difference for nitrogen uptake and recovery by plants.
