Because of its high selling price and low cost of production, farmers in the Central Gondar Zone showed great interest in mungbean production. However, the best-adapted varieties and the effectiveness of commercial Rhizobium inoculants were not determined. Hence, a study was conducted for two consecutive years to evaluate the adaptability and agronomic performances of mungbean varieties under non-inoculated and inoculated conditions.
A factorial combination of five mungbean varieties (Shewarobit, NVL-1, Rasa, Boreda, and Arkebe) and two inoculation levels were arranged in randomised complete block design with three replications. Data concerning flowering and maturity, nodulation, plant height, number of main branches and pods, hundred seed weight, biological and seed yields, and harvest index were collected and analyzed using R software.
The study provided valuable insights into how variety and inoculation affect mungbean growth and yield. Inoculated seeds of Rasa, Boreda, and Arkebe took longer to flower (42.00, 40.17, and 32.33 days) and mature (86.33, 85.67, and 74.67 days), but in return, they produced more nodules (5.37, 4.83, and 2.77), branches (6.97, 6.75, and 6.45), and pods (11.83, 10.73, and 11.27) than their non-inoculated counterparts. However, no significant differences were seen for Shewarobit and NVL-1 varieties. The 2021 experiment outperformed 2022, showing higher nodules, pods, harvest index, and both biological and seed yields. Variety also played a significant role, influencing stand count, plant height, hundred seed weight, and harvest index. In 2021, the interaction of variety and inoculation affected biological and seed yields, while in 2022, only variety did. Rhizobium inoculation showed inconsistent effects on mungbean yield, suggesting the need for further investigation. The top performers in seed yield were Shewarobit (660.90-1,214.74 kg ha) and NVL-1 (532.35-1,097.78 kg ha), followed closely by Rasa (521.99-1,095.00 kg ha) and Boreda (546.70-1,106.63 kg ha), with Arkebe (367.85-606.88 kg ha) yielding the lowest.
Mungbean farmers in the Central Gondar Zone should prioritize Shewarobit and NVL-1 for the highest seed yields, with Rasa and Boreda as strong alternatives.
由于绿豆售价高且生产成本低，中贡德尔地区的农民对绿豆生产表现出极大兴趣。然而，尚未确定最适宜的品种以及商业根瘤菌接种剂的有效性。因此，连续两年开展了一项研究，以评估绿豆品种在未接种和接种条件下的适应性及农艺性能。
将五个绿豆品种（Shewarobit、NVL - 1、Rasa、Boreda和Arkebe）与两种接种水平进行析因组合，采用随机完全区组设计，重复三次。收集有关开花和成熟、结瘤、株高、主枝和豆荚数量、百粒重、生物产量和种子产量以及收获指数的数据，并使用R软件进行分析。
该研究为品种和接种如何影响绿豆生长和产量提供了有价值的见解。接种的Rasa、Boreda和Arkebe种子开花（分别为42.00、40.17和32.33天）和成熟（分别为86.33、85.67和74.67天）所需时间更长，但相应地，它们比未接种的同类品种产生了更多的根瘤（分别为5.37、4.83和2.77个）、枝条（分别为6.97、6.75和6.45个）和豆荚（分别为11.83、10.73和11.27个）。然而，Shewarobit和NVL - 1品种未观察到显著差异。2021年的试验表现优于2022年，根瘤、豆荚、收获指数以及生物产量和种子产量均更高。品种也发挥了重要作用，影响着株数、株高、百粒重和收获指数。2021年，品种与接种的相互作用影响生物产量和种子产量，而在2022年，仅品种有影响。根瘤菌接种对绿豆产量的影响不一致，表明需要进一步研究。种子产量最高的是Shewarobit（660.90 - 1214.74千克/公顷）和NVL - 1（532.35 - 1097.78千克/公顷），其次是Rasa（521.99 - 1095.00千克/公顷）和Boreda（546.70 - 1106.63千克/公顷），Arkebe（367.85 - 606.88千克/公顷）产量最低。
中贡德尔地区的绿豆种植户应以Shewarobit和NVL - 1为优先选择，以实现最高种子产量，Rasa和Boreda为有力备选品种。
