Abstract

The field research was conducted to determine the different levels of phosphorus and zinc on growth and yield of wheat crop at Latif Experimental Farm Sindh Agriculture University Tando Jam Pakistan. The soil was clay loam in texture non saline EC 0.94 dS/m alkaline pH 8.2 calcareous CaCo3 10.5 low in organic matter 0.98 available phosphorus 5.75 mg kg-1 total nitrogen content was 0.05 and available zinc content was 0.78 mgkg-1. The wheat variety TD-1 was treated with 0-5 0-10 60-5 90-5 120-5 60-10 90-10 and 120-10Kg ha-1 P-Zn with recommended N 160 kg ha-1. The taller plants 75.87 cm longer spikes 8.92 cm higher tillers plant-1 4.00 maximum grains spike-1 36.80 heavier seed index 37.81g superior with the incorporation of 90 kg P 10 kg Zn ha-1. The maximum phosphorus in straw 0.092 and in grain 0.419 were noted with the incorporation of 120 kg P Zn ha-1. The zinc content in straw 76.33 mg kg-1 and in grain 92.22 mg kg-1 was found higher under 0 kg P 10 kg Zn ha-1. The available P content of soil increased from 5.75 and 30 mg kg-1 to 11.94 and 9.28 mg kg-1 at the depth of 0-15 and 15-30 cm respectively where P at the rate of 120 kg and 5 kg Zn ha-1 was applied to the crop. The Zn content soil also increased from 0.78 to 0.61 mg kg-1 to 1.39 to 1.24 mg kg-1 at the depths of 0-15xand 15-30 cm respectively under application of 0 kg P 10 kg Zn ha-1. Thus it was concluded that micronutrients are essential for uptake of nitrogen and maximum straw and grain yield could be achieved from phosphorus at the rate of 90 kg ha-1 and 10kf Zn ha-1 with the recommended does of 160 kg N ha-1.
