摘要
磷对作物的生长和产量起着至关重要的作用，因此，2023 年春季在乌罗兹甘省高等教育研究所的研究农场进行了一项名为 "乌罗兹甘农业生态条件下玉米施磷量优化 "的田间试验，以评估不同剂量的磷对玉米生长和产量的影响。试验采用随机完全区组设计，重复三次，数据采用 IBM SPSS 24 进行分析。与对照相比，施磷量对玉米的生长、产量和产量属性有明显影响，当施磷量从 20 kg P2O5 ha-1 增加到 80 kg P2O5 ha-1 时，作物的生长、产量和产量属性持续增加。试验结果表明，在乌罗兹甘省的农业生态条件下施用磷肥可以提高作物的生长、产量和产量属性。
Optimization of Phosphorus Application Rate on Maize Under Agro-ecological Condition of Urozgan
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.
