Abstract:
Four levels of phosphorus (control, 45, 90 and 135 kg per hectare) with four methods of application (broadcast, 5 cm below the seed, 5 cm below and 5 cm to the side of seed and In middle of rows) were tested on a non-saline alkaline calcareous soil of Faisalabad during 1971, in order to study their effect on the grain yield and phosphorus uptake by maize during the summer. Nitrogen at the rate of 135 kg per hectare as urea was applied as basal dose of fertilizer. The results Indicated that the application of triple superphosphate significantly increased the yield and this increase was the maximum at 135 kg P205 per hectare. Banding fertilizer 5 cm below the seed, 5 cm below and 5 cm to the side of seed was approximately as effective as twice the amount applied as broadcast. Among all the fertilized plots with the same phosphorus rate, placement 5 cm below the seed, 5 cm below and 5 cm to the side of seed gave better results In yield. The quality of grain improved wish increase in ash, nitrogen and phosphorus contents.
