摘要
背景:土壤肥力下降是埃塞俄比亚农作物生产的严重瓶颈。施用无机肥料有助于纠正特定地点的营养缺乏。方法:研究于2020年12月至2021年7月在Achura kebele农民培训中心(FTC)进行。土壤样品和作物数据按标准程序收集和分析。结果:土壤反应显示土壤为中酸性(pH=5.68)，有机碳、全氮、速效磷、钾、硫、硼含量较低。结果表明，氮、磷、硫、硼和钾肥配施对玉米的生长和产量影响显著(P < 0.05)。籽粒产量最高的是NPSB、200 kg ha-1 + K和50 kg ha-1，最低的是对照。
Response of Maize (Zea mays L.) to Blend (Nitrogen, Phosphorus, Sulfur, Boron) and Potassium Fertilizers Rates at Boloso Sore Woreda, Ethiopia
Background: The declining soil fertility is a severe bottleneck for crop production in Ethiopia. The application of inorganic fertilizer helps to correct a site-specific nutrient deficiency. Methods: The research was conducted at Achura kebele Farmers Training Center (FTC) from December 2020 to July 2021. Soil samples and crop data were collected and analyzed by standard procedures. Result: The soil reaction revealed that the soil was moderately acidic (pH=5.68) and low in organic carbon, total nitrogen, available phosphorus, potassium, sulfur and boron. The result of this study indicated that the growth and yield of maize were significantly (P less than 0.05) affected by the combined effect of both blended (nitrogen, phosphorus, sulfur, boron) and potassium fertilizer rates. The highest grain yield (7200.9 kg ha-1) was found from NPSB, 200 kg ha-1 + K, 50 kg ha-1and the lowest was recorded from control.
