Abstract

The effect of organic fertilizers was evaluated on the nutritional parameters of Moringa oleifera in the field at a year after transplantation. The study was conducted in a completely randomized block design comprising six treatments each of which was replicated four times. Physicochemical properties of leaves and seeds sampled from treatments (cow dung compost, goat manure compost, poultry manure compost, chemical fertilizer, mixture of fertilizers and control) were assessed. Results obtained indicate that dried leaves of M. oleifera from poultry manure compost contain a high total protein content (41.83%). Seeds harvested from composted plants were rich in nutrients than leaves, with the exception of vitamin C, which was more concentrated in leaves than seeds. Vitamin C contents in dry leaves from cow dung compost and the mixture of fertilizers were 734 and 964.50 mg/100g, respectively. Applying plants with compost resulted in increasing chlorophyll a and b in leaves, but not carotenoid. On the overall, organic fertilizers contributed to the improvement of the nutritional quality of M. oleifera leaves and seeds under field conditions.

摘要

在移植一年后，评估有机肥对辣木在田间的营养参数的影响。该研究采用完全随机区组设计，包括六个处理，每个处理重复四次。评估了从处理（牛粪堆肥、山羊粪便堆肥、家禽粪便堆肥、化肥、肥料混合物和对照）中取样的叶子和种子的理化特性。获得的结果表明，M. oleifera 的干叶来自家禽粪便的堆肥含有高总蛋白质含量 (41.83%)。从堆肥植物中收获的种子比叶子含有丰富的营养，但维生素 C 除外，它在叶子中比种子中更集中。牛粪堆肥和混合肥料的干叶中维生素C含量分别为734和964.50 mg/100g。给植物施用堆肥会增加叶子中的叶绿素 a 和 b，但不会增加类胡萝卜素。总体而言，有机肥有助于改善大田条件下油菜叶和种子的营养品质。
