Abstract

Low soil fertility is one of the major factors limiting the yield of barley in Kaffa Zone, south-western Ethiopia. The problem is more severe in the Zone due to soil erosion and nutrient leaching caused by heavy and continuous rainfall. Thus, field experiment was conducted to assess the effect of combined organic and mineral nitrogen (N) and phosphorus (P) on selected soil physico-chemical properties and on grain yield of food barley in Ghimbo and Adiyo districts, south-western Ethiopia. Fourteen treatments comprising two organic fertilizer rates, i.e. 2.5 and 5 t ha −1 of Farm Yard Manure (FYM) and Vermicomost (VC) combined with three levels of mineral NP (25, 50 and 75% of recommended rates of NP), 100% recommended rate of inorganic NP (23 kg N ha -1 and 46 kg P 2 O 5 ha -1 ) and no fertilizer application (control) in randomized complete block design on clay soil in Ghimbo and clay loam soil in Adiyo with three replications. Results indicated that the application of FYM in combination with different levels of recommended rates of inorganic N and P significantly improved most of the soil physico-chemical properties and significantly increased the grain yield of food barley over the application of 100% mineral NP alone and the control. The application of 5 t FYM ha −1 in combination with 75% recommended rates of inorganic N and P (17.25 kg N ha −1 and 34.5 kg P 2 O 5 ha −1 ) was found to be superior and increased soil organic carbon content by 36 and 44.6%, available P by 70.5 and 78.2%, available K by 42.5 and 26.3%, and increased yield of barley by 76.8 and 83.5% in Adiyo and Ghimbo, respectively, over the application of 100% recommended rate of inorganic N and P only. Therefore, it can be concluded and recommended that the application of 5 t FYM ha −1 in combination with 75% of the recommended rates of inorganic N and P (17.25 kg N ha −1 and 34.5 kg P 2 O 5 ha −1 ) can improve soil fertility and can increase yield of food barley in the study area.

有机与无机氮磷肥配施对埃塞俄比亚西南部Kaffa地区食用大麦土壤理化性质及产量的影响

土壤肥力低是限制埃塞俄比亚西南部Kaffa地区大麦产量的主要因素之一。由于强降雨和持续降雨造成的土壤侵蚀和养分流失，该地区的问题更加严重。因此，在埃塞俄比亚西南部的Ghimbo和Adiyo地区进行了田间试验，以评估有机和矿物氮（N）和磷（P）对选定土壤物理化学性质和粮食大麦产量的影响。14个处理包括两种有机肥料施用率，即2.5和5 t ha−1的农田肥料（FYM）和Vermicmost（VC）与三种水平的矿物NP（NP推荐施用率的25%、50%和75%），在Ghimbo粘土和Adiyo粘壤土上进行的随机完全块区设计中，无机NP（23 kg N ha-1和46 kg P 2 O 5 ha-1）和不施肥（对照）的推荐率为100%，三次重复。结果表明，与单独施用100%无机氮磷和对照相比，FYM与不同无机氮磷推荐施用水平的组合显著改善了大部分土壤理化性质，并显著提高了粮食大麦的产量。施用5 t FYM ha−1与75%的无机氮和磷推荐量（17.25 kg N ha−1和34.5 kg P 2 O 5 ha−1）效果较好，分别使阿迪约和吉姆博的土壤有机碳含量增加了36和44.6%，有效磷增加了70.5和78.2%，有效钾增加了42.5和26.3%，大麦产量增加了76.8和83.5%，超过仅施用100%推荐速率的无机氮和磷。因此，可以得出结论并建议，5 t FYM ha−1与75%的无机氮和磷推荐施用量（17.25 kg N ha−1和34.5 kg P 2 O 5 ha−1）相结合，可以提高研究区的土壤肥力，并可以提高食用大麦的产量。关键词：农家肥，氮，磷，蚯蚓粪，埃塞俄比亚。
