Abstract
Aims
Sustainable crop production is constrained by imbalanced fertilization and poor soil management, which lead to reduced soil fertility. Additionally, water hyacinth poses a major threat to Tana Lake by disrupting ecosystems and degrading water quality. A field experiment conducted in the Lake Tana Basin during the 2022/2023 cropping season aimed to assess the impact of combining water hyacinth compost and blended mineral fertilizer on soil properties and wheat yield attributes.
Methods
The study tested four rates of water hyacinth compost (0, 5, 10, 15 t ha⁻¹) and four rates of blended mineral fertilizer (0%, 50%, 75%, and 100% of NPSB recommended rates) in a randomized complete block design with triplicates. Data on soil properties and wheat yield were analyzed using SAS-JMP17 software.
Results
The combined application of both fertilizers significantly (p < 0.05) improved the total nitrogen and agronomic attributes of wheat. The highest total nitrogen was achieved with 15 t ha⁻¹ of compost and full-rate blended fertilizer, while the highest soil reaction, organic carbon, and cation exchange capacity were observed with 15 t ha⁻¹ compost alone. The best wheat yield (4.15 t ha⁻¹) and net benefit (131,912.73 ETB ha⁻¹) were obtained with 15 t ha⁻¹ compost and full-rate blended fertilizer. Grain yield increased by 312.35% and 28.09% compared to the control and blanket recommendation of blended mineral fertilizer.
Conclusions
Using 15 t ha⁻¹ of compost with the full recommended rate of blended fertilizer enhances wheat production and provides a sustainable solution for managing invasive water hyacinth in similar regions.
目的作物的可持续生产受到施肥不平衡和土壤管理不善的制约,导致土壤肥力下降。此外,水葫芦通过破坏生态系统和降低水质对塔纳湖构成重大威胁。为了评估水葫芦堆肥与混合矿肥配施对土壤性状和小麦产量属性的影响,于2022/2023种植季在塔纳湖流域进行了田间试验。方法 水葫芦堆肥的研究测试了四个利率(0、5、10、15 t公顷⁻¹)和四个混合矿物肥料率(0%,50%,75%,和100%的NPSB推荐率)在随机完全区组设计一式三份。利用SAS-JMP17软件对土壤性质和小麦产量数据进行分析。结果两肥配施显著(p < 0.05)提高了小麦全氮和农艺性状。总氮量最高的是15 t ha -毒血症混合肥料,而土壤反应、有机碳和阳离子交换能力最高的是15 t ha -毒血症混合肥料。使用15吨的堆肥和全速率的混合肥料可以获得最好的小麦产量(4.15吨/⁻)和净效益(131,912.73吨/⁻)。与对照剂和地铺推荐剂相比,籽粒产量分别提高312.35%和28.09%。结论15公顷- 1公顷的堆肥配合推荐比例的混合肥料可提高小麦产量,并为类似地区管理入侵水葫芦提供了可持续的解决方案。
