Effect of integrated nitrogen management on available N, P and CO_2 evolution at different intervals under wheat (Triticum aestivum) cultivation

摘要

A field experiment was conducted at Agronomy Farm, Rajasthan College of Agriculture, Udaipur (Rajasthan) during rabi season of 2005-06 to evaluate the effect of integrated nitrogen management on available N, P and CO_2 evolution at different intervalsunder wheat cultivation. The results indicated that application of nitrogen through organic manure or in integration with chemical fertilizer significantly improved the available N, P and CO_2, evolution at 7,15, 30 and 45 days after sowing and organiccarbon at harvest.
