Maize fodder yield was determined under various nitrogen and phosphorus doses under sub-humid rainfed conditions during 2009 at PMAS-Arid Agriculture University, Rawalpindi, Pakistan. The annual rainfall at the experimental site during 2009 was 685.9 mm. The experimental soil was of loamy texture having E.C. of 0.48 dscm-1 pH 7.7, organic matter 0.65%, saturation 30%, available phosphorus 5.7 mg kg-1 and available potassium 78 mg kg-1 Maize cv. Sargodha-2002 was sown in randomized complete block design (factorial) and was fertilized with four each nitrogen @ 0, 60, 120 and 180 kg ha-1 and phosphorus 0, 30, 60 and 90 kg ha-1 doses. Significant increase in green fodder and dry matter yield was observed with the increased doses of nitrogen and phosphorus. Overall, the nitrogen application @ 180 kg ha-1 increased the green fodder and dry matter yield by 12.33% and 51.50%, respectively. Similarly, with phosphorus application @ 90 kg ha-1 the 36.80% and 46.26% increase was observed in green fodder and dry matter yield, respectively. In combination of nitrogen and phosphorus @ 180:90 NP kg ha-1 there was a significant increase in green fodder and dry matter yields through their interactive effect, that were 90.19% and 159.31%, respectively. This increase may be due to increase in vegetative growth parameters like plant height, stem diameter and leaf area. It was concluded that fertilizers combination of 180:90 NP kg ha-1 was recommended for obtaining higher maize fodder yield under rainfed conditions of Rawalpindi, Pakistan. [ABSTRACT FROM AUTHOR]
