摘要

The nutritional effects of green manure on soil and crop plants depends on residue quality. Hence field experiments were carried out during the cropping seasons of 2015 and 2016 to compare the impact of different green manures and NPK 15-15-15 fertilizer on soil properties, growth, yield, mineral and vitamin C composition of okra ( Abelmoschus esculentus (L.) Moench). The experiment each year consisted of four green manure (GM) types {Pawpaw ( Carica papaya L.) leaves, Neem ( Azadirachta indica A. Juss.) leaves, Moringa ( Moringa oleifera Lam.) leaves, and Mesquite ( Prosopis africana Guill., Perr. & A. Rich) Taubert leaves}, NPK 15-15-15 fertilizer and a control. The six treatments were arranged in a randomized complete block design with four replications. Application of GMs reduced soil bulk density and increased soil organic matter (OM), N, P, K, Ca, Mg, growth and yield of okra compared with the control. NPK fertilizer did not reduce soil bulk density and increase soil OM, but did increase soil N, P, K, Ca, Mg, growth and yield of okra compared with the control. Mesquite increased growth and yield of okra compared with NPK fertilizer and other GMs. This was due to increased availability of N and K in the soil at the level of this treatment. Using the means of the two years and compared with the control and NPK fertilizer, Mesquite increased pod yield of okra by 214 and 53%, respectively. Also GMs and NPK fertilizer increased okra mineral and vitamin C contents compared with the control. Moringa had the best fruit quality in terms of higher K, Ca, Fe, Zn, Cu, and vitamin C contents compared with other GMs and NPK fertilizer. Therefore, for those that desire to grow okra for the quality of its fruits, Moringa ( Moringa oleifera ) is recommended, however for those that desire quantity, Mesquite ( Prosopis africana ) is recommended.

Juss。））叶子，辣木（Moringa oleifera Lam。）叶子和豆科灌木（Prosopis africana Guill。 ，Perr。＆A. Rich）Taubert leaves}，NPK 15-15-15肥料和对照。六种治疗以随机完整区组设计排列，重复四次。与对照相比，转基因植物的施用降低了土壤容重，增加了土壤有机质（OM），N，P，K，Ca，Mg，秋葵的生长和产量。与对照相比，氮磷钾肥没有降低土壤容重和增加土壤有机质，但是却增加了土壤氮，磷，钾，钙，镁，黄秋葵的生长和产量。与NPK肥料和其他转基因肥料相比，豆科灌木提高了秋葵的生长和产量。这是由于在此处理水平下土壤中N和K的有效性增加。使用两年的方法，与对照和NPK肥料相比，豆科灌木将秋葵的荚果产量分别提高了214％和53％。与对照相比，转基因和NPK肥料还增加了秋葵的矿物质和维生素C的含量。与其他转基因和NPK肥料相比，辣木的K，Ca，Fe，Zn，Cu和维生素C含量更高，具有最好的果实品质。因此，对于那些希望以其果实的品质来生长秋葵的人，推荐使用辣木（Moringa oleifera），而对于那些想要数量的人，则建议使用豆科灌木（Prosopis africana）。
