Interference of weeds on Barbados gooseberry initial development

ABSTRACT The Barbados gooseberry crop has agricultural potential, but little information is available regarding cropping practices. More information on weed interference in Barbados gooseberry will support growers to take weed management decisions. The objective of this work was to study initial growth and development of Barbados gooseberry under the interference of weeds. The experiment was conducted in a completely randomized design, with five treatments, composed of Barbados gooseberry in competition with four weed species: slender amaranth (Amaranthus viridis), hairy beggarticks (Bidens pilosa), Benghal dayflower (Commelina benghalensis), purple nutsedge (Cyperus rotundus), and a weed-free control, with six replicates. Weed competition led to a decrease in growth and development of Barbados gooseberry reflected in a reduction of up to 40% in yield and 23% in protein content. Additional work must be conducted evaluating these findings under field conditions, using different seedling production and planting techniques potentially affecting these results.摘要：巴巴多斯醋栗（Barbados gooseberry）具备农业开发潜力，但目前关于其栽培管理措施的相关信息较为匮乏。深入明确巴巴多斯醋栗田间的杂草干扰效应，可为种植者制定杂草防控决策提供支撑。本研究旨在探究杂草干扰条件下巴巴多斯醋栗的初始生长与发育规律。试验采用完全随机设计，共设置5组处理：巴巴多斯醋栗分别与4种杂草（凹头苋<slender amaranth, Amaranthus viridis>、三叶鬼针草<hairy beggarticks, Bidens pilosa>、孟加拉鸭跖草<Benghal dayflower, Commelina benghalensis>、香附子<purple nutsedge, Cyperus rotundus>）竞争生长，以及无杂草对照组，每组处理设置6次重复。结果表明，杂草竞争会抑制巴巴多斯醋栗的生长发育，使其产量最高下降40%，蛋白质含量降低23%。后续需开展田间条件下的验证试验，并采用不同育苗与种植技术，以明确其对该试验结果的潜在影响。
