摘要

蚕豆(Vicia Faba L.)是最重要的冬季豆科作物之一,可作为绿色或干燥,新鲜或罐装供人类食用。土壤肥力和酸度低是埃塞俄比亚蚕豆生产的主要制约因素。在埃塞俄比亚西奥罗米亚州Kiremu地区,在雨养条件下,在一农户田间进行了田间试验,评价了接种和不接种不同剂量石灰和npsb混合肥料对蚕豆产量组成和产量的影响。在3个重复中,将石灰用量(0、2和4 t ha−1)、矿物肥用量(0、60、120和180 kg·ha−1 NPSB)和根瘤菌接种(含和不含)这3个因素组合在RCBD的3 × 4 × 2因子安排中。收集产量和产量成分数据,进行方差分析(ANOVA)。方差分析结果表明,处理对单株荚果数、荚果数、百粒重、收获指数、地上生物量和籽粒产量均有显著影响。综上所示,2 t石灰/ ha - 1、120 NPSB / ha - 1和500 g·ha - 1根瘤菌接种量可获得最高的蚕豆产量。因此,建议综合施用上述石灰、NPSB和根瘤菌接种量,以最大限度地提高研究区和类似农业生态区蚕豆生产的生产力效益。

Yield Response of Faba Bean to Lime, NPSB, and Rhizobium Inoculation in Kiremu District, Western Ethiopia
Faba bean (Vicia faba L.) is one of the most important winter legume crops for human consumption as a green or dried, fresh, or canned. Low soil fertility and acidity are the major constraints of faba bean production in Ethiopia. A field experiment was conducted in the Kiremu district of West Oromia, Ethiopia, under rain-fed conditions on a farmer's field to evaluate the effect of different rates of lime and NPSB-blended fertilizer application with and without inoculation on yield components and yield of faba bean. The three factors, lime rates (0, 2, and 4 t ha−1), mineral fertilizer rates (0, 60, 120, and 180 kg·ha−1 NPSB), and rhizobium inoculation (with and without), were combined in 3 x 4 x 2 factorial arrangement of RCBD in three replications. The data were collected on yield and yield components and subjected to the analysis of variance (ANOVA). The ANOVA results revealed that the number of pods per plant, number of seeds per pod, hundred seeds weight, harvest index, aboveground biomass, and grain yield were significantly affected by the treatment. Therefore, the highest faba bean yield was obtained from the application of 2 t limes ha−1, 120 NPSB ha−1, and 500 g·ha−1 rhizobium inoculation, and thus, the integrated application of the aforementioned rates of lime, NPSB, and rhizobium inoculation could be recommended for maximizing the productivity profitability of faba bean production in the study area and similar agro-ecologies.

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
