Abstract
Application of inorganic and organic fertilizers is the cheapest sources for replenishing plant nutrients in agricultural soils. However, selecting the optimum combination of these resources based on soil type and crop species were necessary. In this view, a field experiment was conducted at Haru research sub-center to assess the effect of coffee husk Compost and NPS Fertilizer rates on soil growth and yield and yield components of coffee in 2018/2019 cropping season. The treatments used were the combination of different rates coffee husk compost and NPS fertilizers rate, and laid out in randomized complete block design with three replications. The combined application of coffee husk compost and NPS fertilizers rate were significantly increased plant height of coffee. Coffee husk compost at (7.5 t ha-1) and NPS fertilizer at (50 kg NPS ha-1) has improved yield of coffee crop. Integrated NPS fertilizer and coffee husk compost with different rates improved coffee yield and yield components. Therefore, the use of 7.5t ha-1 coffee husk compost and 50 kg ha-1 of NPS fertilizer can be the best alternative integrated soil fertility management option in place of the sole application of inorganic fertilizers at study area tentatively. Nevertheless, in order to give conclusive recommendation further research studies are needed for more soil types and coffee crop varieties.
施用无机和有机肥料是农业土壤中补充植物养分的最便宜的来源。然而,根据土壤类型和作物种类选择这些资源的最佳组合是必要的。为此,在春研究分中心开展了2018/2019种植季咖啡皮堆肥和NPS施肥量对土壤生长和咖啡产量及产量成分的影响的田间试验。采用不同用量咖啡壳堆肥和NPS肥料组合处理,采用随机完全区组设计,每组3个重复。咖啡壳堆肥与NPS肥配施可显著提高咖啡株高。咖啡壳堆肥(7.5 t hm -1)和NPS肥料(50 kg NPS hm -1)提高了咖啡作物的产量。不同配比的NPS肥与咖啡壳堆肥配合施用,提高了咖啡产量和产量组成。因此,在研究区,施用7.5t ha-1的咖啡壳堆肥和50 kg ha-1的NPS肥可作为代替单施无机肥的最佳替代土壤综合肥力管理方案。然而,为了给出结论性的建议,需要对更多的土壤类型和咖啡作物品种进行进一步的研究。
