Abstract

A field experiment Conducted at the farm of Kunduz University during cropping season of 2023 to evaluate Effects of Nitrogen Application on Growth and Yield of Groundnut (Arachis hypogaea L.) in northeast of Afghanistan. The field experiment laid out in Randomized Complete Block Design with three replications, the treatments were Nitrogen fertilizer levels viz. Control, 15 kg N/ha, 30 kg N/ha and 45 kg N/ha respectively, result of the study revealed the highest Plant Height (32.61cm), Branches/plant (10.05), Leave area index (5.20), Kernel/pod (2.23), Pod weight (24.46), Pods/plant (32.30), 100- seed weight (76.38gr), Pod yield (2.89t/ha), haulm yield (5.53t/ha) and Biological yield (8.42t/ha) were in treatment with application 45 kg N/ha, the minimum growth and yield parameters were in Control plots, it can be concluded nitrogen fertilizer at the rate of 45 kg N/ha is optimum level for enhancing groundnut productivity and profitability in northeast of Afghanistan.

施氮对阿富汗东北部农业生态区落花生（Arachis hypogaea L.）生长和产量的影响

2023 年种植季节，在昆都士大学农场进行了一项田间试验，以评估施氮对阿富汗东北部落花生（Arachis hypogaea L.）生长和产量的影响。田间试验采用随机整群设计，三次重复，处理为氮肥水平，分别为对照、15 千克氮/公顷、30 千克氮/公顷和 45 千克氮/公顷，研究结果表明，施用氮肥后，花生的株高（32.61 厘米）、分枝/株（10.05）、叶面积指数（5.20）、籽粒/荚（2.23）、荚重（24.46）、荚/株（32.在施用 45 公斤氮肥/公顷的处理中，荚果产量（2.89 吨/公顷）、茎秆产量（5.53 吨/公顷）和生物产量（8.42 吨/公顷）均有所提高，而对照地块的生长和产量参数最低。
