Abstract
Multi-nutrients deficiency of soil in southwest Ethiopia is among the primary constraints for the very low productivity of potatoes (Solanum tuberosum L.). The combined use of organic and inorganic fertilizers is vital for resolving the common productivity issue. Thus, experiments were performed on potato variety “Belte” in Masha district, southwestern Ethiopia, in both Belg (February to May) as well as Meher (June to October) seasons of 2019 to evaluate the potato response to the vermicompost, mineral phosphorus, and nitrogen’s integrated applications. The experiment had three vermicompost rates with the factorial combination (2.5, 5, 7.5 t/ha) and three recommended rates inorganic NP’s 25%, 50% and 75% (124 kg N/ha and 103 kg P2O5/ha) fertilizer. Results have discovered that 75% inorganic NP and 7.5 t/ha vermicompost’s combined application significantly increase total tuber yield, marketable tuber yield, and individual tuber weight, giving the maximum net benefits and marginal return rate. Thus, it has been discovered from this work that for potato production at Masha area, 7.5 t/ha vermicompost with inorganic NP’s 75% recommended dose’s combined applications are best-integrated nutrient management options.
埃塞俄比亚西南部土壤缺乏多种养分是马铃薯(Solanum tuberosum L.)生产力极低的主要制约因素之一。有机和无机肥料的联合使用对于解决常见的生产力问题至关重要。因此,在2019年的Belg(2月至5月)和Meher(6月至10月)季节,对埃塞俄比亚西南部马沙区的马铃薯品种“Belte”进行了实验,以评估马铃薯对蚯蚓堆肥、矿物磷和氮的综合应用的反应。试验采用因子组合(2.5、5、7.5 t/ha)和三种推荐的无机NP(25%、50%和75%)肥料(124 kg N/ha和103 kg P2O5/ha)进行三种蚯蚓堆肥。结果表明,75%无机NP和7.5t/ha粉丝堆肥的联合施用显著提高了块茎总产量、商品块茎产量和单株块茎重量,使净效益和边际收益率最大。因此,从这项工作中发现,对于马沙地区的土豆生产,7.5吨/公顷的蚯蚓堆肥与无机NP的75%推荐剂量的组合应用是最佳的综合营养管理选择。
