EFFECT OF INTEGRATED NITROGEN MANAGEMENT ON AVAILABLE N, P AND CO2 EVOLUTION AT DIFFERENT INTERVALS UNDER WHEAT (TRITICUM AESTIVUM) CULTIVATIONJ.P. Yadav1, A.K. Mathur1 and K.K. Yadav2Abstract 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 CO2 evolution at different intervals under 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 CO2 evolution at 7, 15, 30 and 45 days after sowing and organic carbon at harvest.
