Abstract
Phosphorus plays a vital role in crop growth and productivity, thus a field experiment entitled (optimization of phosphorus application rate on maize under agro-ecological condition of Urozgan) was conducted at Urozgan Higher Education Institute research farm, during spring season of 2023 to evaluate the effects of various doses of phosphorus on maize growth and yield. Treatments were consisted of four levels of phosphorus 20, 40, 60, 80 Kg P2O5 ha-1 and control, the experiment was laid out in randomized complete block design and replicated thrice, the data was analyzed by IBM SPSS 24. Phosphorus application significantly influenced maize growth, yield and yield attributes compared to control, while the phosphorus doses increased from 20 to 80 kg P2O5 ha-1, crop growth, yield, and yield attribute were continuously increased. It can be concluded from the result of experiment that application of phosphorus under agro-ecological condition of Urozgan can increase crop growth, yield and yield attributes.
