摘要

巴西北部地区一直在经历农业和城市扩张,导致需要经济替代方案来减少森林砍伐和增加粮食供应。一种可能是种植容易种植的蔬菜,比如甘薯。这项工作的目的是评估甘薯基因型在巴西马拉布三个不同种植季节的表现。采用随机区组试验设计评估甘薯基因型,并在收获时评估最终植株林分和商品根产量。11号无性系是所有种植期产量最高的无性系,商业产量为80.4 ~ 127吨/公顷。加拿大玉米的产量也很高,是产量最高的基因型之一。CIP BRS Nuti在前两个生长季节的商业产量与Beauregard相似,但在第三个种植周期的产量更高。收获期水分较高的第一季根系质量最低。然而,总的来说,所有品种都表现良好,是种植者在小面积生产高质量和高产量食物来源的良好选择。

Sweetpotato as an alternative crop for vegetable growers in Marabá-PA
ABSTRACT The north region of Brazil has been experiencing agricultural and urban expansion leading to the need for economic alternatives to reduce deforestation and to increase food supply. One possibility is the cultivation of vegetables that are easily grown such as the sweetpotato. The objective of this work is to assess the performance of sweetpotato genotypes in three different planting seasons in Marabá, Brazil. Sweetpotato genotypes were evaluated using randomized block experimental design and at harvest time the final plant stand and the commercial root production were evaluated. Clone 11 was the most productive one in all planting dates, with commercial yield ranging from 80.4 to 127 t/ha. Canadense also was very productive and among the top yielding genotypes. CIP BRS Nuti’s commercial yield was similar to Beauregard’s in the two initial growing seasons but higher in the third planting cycle. The first season, that had high moisture during harvest time, presented the lowest root quality. However, in general, all cultivars performed well, being good options for growers to produce a food source with high quality and yield in small areas.
