Abstract

Red radish is a nutritious root vegetable crop that has a short production cycle. Water deficit limits plant productivity, affecting its quantity and quality. Compost amendment offers a potential solution to mitigate water deficit effects. This study assessed the impact of compost manure rates (0%, 50%, 75%, and 100%) and irrigation treatments (40%, 60%, 80%, and 100% of evapotranspiration) on ‘Crimson Giant’ red radish production. Significant differences in growth and quality were observed among these treatments. Compost rates of 75% and 100% improved leaf gas exchange, plant growth (leaf count, fresh weight, dry weight, and area; stem length), root development, total yield (root fresh weight, dry weight, diameter, and length), and root quality (vitamin C and total soluble solid and titratable acidity). The 100% compost and 100% irrigation combination achieved the highest yields. Under water deficit, applying 75% or 100% compost with 80% irrigation conserved 20% of water while maintaining radish output. Overall, compost amendment effectively enhanced red radish growth and production under water deficit.

堆肥改良剂可增强缺水的 "深红巨人 "红萝卜(Raphanus sativus L.)的叶片气体交换、生长和产量
红萝卜是一种营养丰富的根茎蔬菜作物,生产周期短。缺水会限制植物的生产力,影响其数量和质量。堆肥添加剂为缓解缺水影响提供了一种潜在的解决方案。本研究评估了堆肥率(0%、50%、75% 和 100%)和灌溉处理(蒸散量的 40%、60%、80% 和 100%)对'Crimson Giant'红萝卜产量的影响。这些处理在生长和质量方面存在显著差异。75% 和 100% 的堆肥率改善了叶片气体交换、植株生长(叶片数、鲜重、干重和面积;茎长)、根系发育、总产量(根系鲜重、干重、直径和长度)和根系质量(维生素 C、总可溶性固体和可滴定酸度)。100% 堆肥和 100% 灌溉的组合产量最高。在缺水情况下,施用 75% 或 100% 堆肥并进行 80% 灌溉可节水 20%,同时保持萝卜产量。总之,堆肥添加剂能在缺水条件下有效提高红萝卜的生长和产量。
