摘要

在莫桑比克,甘薯在农村地区发挥着重要作用,农民用甘薯来养家糊口并赚取收入。在这项研究中,我们旨在调查莫桑比克尼亚萨地区不同甘薯品种的表现。试验地点位于桑加区的马卢卢,距离莫桑比克尼亚萨首府利钦加 60 公里。桑加的雨季和热季为 12 月至次年 3 月,旱季和冷季为 5 月至 10 月。在该试验中,处理与甘薯品种相对应。我们采用随机区组设计,共有 12 个甘薯品种和 3 个重复。评估的性状如下:象鼻虫危害、根茎商品产量、根茎非商业产量、总产量和藤蔓产量。在统计分析方面,对每个性状的结果进行了巴特利特(Bartlett)方差齐性检验和夏皮罗-维尔克(Shapiro-Wilk)正态检验,然后进行方差分析,必要时使用斯科特-克诺特(Scott-Knott)检验进行均值比较。所有统计分析均使用 5% 的 R 编程语言进行。在商品产量和总产量方面,本地、苏马亚、奥尔加和阿丽莎等品种的结果最好。埃斯特和艾琳是受象鼻虫侵害最严重的品种。

Evaluation of Some Sweetpotato (Ipomoea batatas [L.] Lam) Varieties in Mozambique
In Mozambique, sweetpotato plays a significant role in rural areas, where the farmers use it to feed their families and as an income. In this study, we aimed to investigate the performance of different sweetpotato varieties in Niassa, Mozambique. The trial was set up in Malulu, Sanga district, located 60 km away from Lichinga, capital of Niassa, Mozambique. In Sanga, the rainy and hot season occurs from December to March, and the dry and cold season is from May to October. In this trial, the treatments correspond to sweetpotato varieties. We used the randomized block design with 12 sweetpotato varieties and 3 replications. The evaluated traits were as follows: weevil damage, roots commercial yield, roots non-commercial yield, total yield, and vine yield. Regarding statistical analysis, the results per trait were submitted to the Bartlett test of homogeneity of variances and Shapiro-Wilk normality test, and then the analysis of variance and means comparison using the Scott-Knott test when necessary was performed. All the statistical analysis was conducted at 5% on the R programming language. For commercial and total yield, the varieties Local, Sumaia, Olga, and Alisha presented the best results. Esther and Irene were the varieties most attacked by weevils.
