An experimental study was conducted to determine the effects of phosphorus applied by various methods in splits on plant population, number of leaves and yield of green fodder maize at the Post Graduate Agricultural Research Farm, Gomal University, D. I. Khan during the kharif season of 2009. The field experiment was conducted in a Randomized Complete Block Design with three blocks. The plot size was kept 3.6 m x 5.0 m. The nitrogen fertilizer was applied in the form of urea in three splits. First split at the time of sowing, second with first irrigation and third with second irrigation. The phosphorus was applied @ 50Kg ha-1. The results revealed that all the treatments under study were significantly influenced all the parameters. The treatment T5 having 2/3 phosphorus at side dressed with first irrigation was proved the best combination in view of maximum plant population, maximum number of leaves and maximum yield of green fodder maize (45.13 t ha-1).
