摘要

在不同的生长区域,普通大豆品种的产量和产量成分对不同水平的钾(K)施肥的反应不同。因此,为了最大限度地提高大豆产量,有必要整合具有最佳K率的品种。另一方面,钾供应不足对气孔的功能有负面影响,延缓气孔关闭,使气孔部分关闭。因此,寻找平衡施钾的高产品种是至关重要的。为了评估不同K率下的普通豆类品种,在2019/20年种植季节,在埃塞俄比亚南部的阿雷卡农业研究中心试验田进行了一项田间试验。处理包括三种常见的豆类品种(SER 119、SAB 736和Awassa Dume)和五种K值(0、10、20、30和40) kg/ha K2O)在析因中组合,并在具有三个重复的随机完全块设计中布置。普通大豆品种的酚性、生长、产量组成和产量对品种、K率及其相互作用的反应不同。单株枝条、叶面积、叶面积指数、单株荚数、生物量和粮食产量等参数受品种、钾肥及其相互作用的显著影响。相反,株高、每荚种子数和HI仅受品种和钾肥用量的主要影响。研究表明,SER 119品种表现出优于其他品种的优异性能,在K率为40时产量最高 千克/公顷。因此,品种SER 119的K速率为40 公斤/公顷可用于研究区域的生产和类似的农业生态。

Effect of Common Bean (Phaseolus vulgaris L.) Varieties and Variable Rates of Potassium Fertilizer on Yield and Yield-Related Traits at Areka, Southern Ethiopia
Yield and yield components of common bean varieties reacted differently in response to variable levels of potassium (K) fertilization under different growing areas. Hence, it is necessary to integrate varieties with optimum K rates in order to maximize bean yield. On the other hand, insufficient K supply has a negative influence on stomata’s functionality, delaying stomatal closure and leaving pores partially closed. Thus, it is essential to find high-yielding varieties with balanced K fertilization. To evaluate common bean varieties at various K rates, a field experiment was carried out during the 2019/20 cropping seasons at the Areka Agricultural Research Center Experimental Field in Southern Ethiopia. Treatments consisted of three common bean varieties (SER 119, SAB 736, and Awassa Dume) and five K rates (0, 10, 20, 30, and 40 kg/ha K2O) combined in factorial and laid out in a randomized complete block design with three replications. The phenological, growth, yield components, and yield of common bean varieties reacted differently to the varieties, K rates, and their interactions. Parameters such as branches per plant, leaf area, LAI, pods per plant, biomass, and grain yield were significantly affected by varieties, K rates, and their interactions. Conversely, plant height, seeds per pod, and HI were significantly affected only by the main effects of varieties and K fertilizer rates. This investigation indicated that variety SER 119 exhibited superior performance over others with the highest grain yield at K rate of 40 kg/ha. Hence, variety SER 119 at K rate of 40 kg/ha could be used for production in the study area and similar agroecologies.

期刊介绍: Applied and Environmental Soil Science is a peer-reviewed, Open Access journal that publishes research and review articles in the field of soil science. Its coverage reflects the multidisciplinary nature of soil science, and focuses on studies that take account of the dynamics and spatial heterogeneity of processes in soil. Basic studies of the physical, chemical, biochemical, and biological properties of soil, innovations in soil analysis, and the development of statistical tools will be published. Among the major environmental issues addressed will be: -Pollution by trace elements and nutrients in excess- Climate change and global warming- Soil stability and erosion- Water quality- Quality of agricultural crops- Plant nutrition- Soil hydrology- Biodiversity of soils- Role of micro- and mesofauna in soil
