Weed Interference on ‘Prata-Anã’ Banana Production

ABSTRACT: In the state of Minas Gerais, the northern region is one of the main banana production cores. Weed interference can reduce crop growth and, consequently, lead to reduced yield and fruit quality. Therefore, the objective of this study was to evaluate the interference of weeds in the production of the first and second cycles of ‘Prata-Anã’ bananas. The experimental design was randomized blocks, with ten treatments and three replicates, evaluated in two crop cycles. The treatments were ten periods of weed control, from planting: without control; control throughout the whole experimental period; control only in the first month after planting; control until the second; third; fourth; fifth; sixth; eighth and tenth months after planting. The agronomic and productive characteristics of the ‘Prata-Anã’ bananas were evaluated aton harvest. The maintenance of ‘Prata-Anã’ bananas without weed coexistence for up to 30 days after planting was enough to obtain fruits with satisfactory quality and productivity, both in the first and in the second production cycle, without altering the vegetative and reproductive cycles.

摘要：巴西米纳斯吉拉斯州北部是当地香蕉主产区之一。杂草干扰会抑制作物生长，进而导致产量下降与果实品质降低。为此，本研究旨在评估杂草对‘普拉塔-阿纳’（Prata-Anã）香蕉头两季生产的干扰效应。试验采用随机区组设计，设置10个处理、3次重复，在两个作物周期内开展评价。处理组为种植后不同时长的杂草防控周期：无杂草防控、全试验周期防控、仅种植后首月防控、分别持续至种植后第2、3、4、5、6、8及10个月时终止防控。在收获期对‘普拉塔-阿纳’香蕉的农艺与生产性状进行了测定。结果显示，在头两季生产中，种植后至多30天内保持该品种香蕉无杂草共生，即可获得品质与产量均达标的果实，且不会改变植株的营养生长与生殖生长周期。
