Use of organic manures to meet the nutrient requirement of crop would be an inevitable practice in the years to come for sustainable agriculture since organic manures generally improve the soil physical, chemical and biological properties. Hence, field experiments were carried out in 2017 and 2018 to compare the impact of different organic manures and NPK fertilizer on soil properties, growth, yield, proximate and mineral contents of okra (Abelmoschus esculentus L.). The treatments each year 2017 and 2018 consisted of: rabbit manure, cow dung, poultry manure, green manure [Mexican sunflower (Tithonia diversifolia Asteraceae)], pig manure, NPK 15-15-15 fertilizer applied at 120 kg N ha⁻¹ and a control (no manure/inorganic fertilizer). The seven treatments were laid out in a randomized complete block design with three replication. Organic manures and NPK fertilizer increased the soil organic matter (OM), N, P, K, Ca and Mg (NPK fertilizer did not increase OM, Ca and Mg significantly), growth, yield, minerals, protein, ash, carbohydrate and mucilage contents of okra fruit as compared with control. Organic manures improved okra yield compared with NPK fertilizer. Okra growth and yield parameters were significantly higher in 2018 compared with 2017. Control, rabbit manure, cow dung, poultry manure, green manure, pig manure and NPK fertilizer in 2018 increased the pod yield of okra by 9.7%, 35.3%, 57.9%, 36.2%, 39.2%, 45.5% and 3.2%, respectively compare with the same treatment in 2017. Amongst various organic manures, poultry manure produced significantly higher plant growth, yield, mineral and proximate composition of okra because of its high soil chemical properties which could be related to its lowest C: N ratio, lignin and lignin: N ratio. Results also showed that okra grown during high intensity rainfall has higher yield but with reduced quality except its mucilage content. Therefore, planting of okra with poultry manure under moderate rainfall will enhance the health benefit from the fruit, however, those that desire its mucilage content planting during high rainfall is recommended.

使用有机肥来满足作物的养分需求将是未来几年可持续农业的必然做法，因为有机肥通常会改善土壤的物理、化学和生物特性。因此，在 2017 年和 2018 年进行了田间试验，以比较不同有机肥和 NPK 肥料对秋葵 ( Abelmoschus esculentus L.)土壤性质、生长、产量、近似含量和矿物质含量的影响。2017年和2018年每年的处理包括：兔粪、牛粪、家禽粪、绿肥[墨西哥向日葵（Tithonia diversifolia Asteraceae）]、猪粪、NPK 15-15-15肥料，施用120 kg N ha ^-1和对照（无肥料/无机肥料）。七种处理以随机完整区组设计进行布置，重复三次。有机肥和 NPK 肥料增加了土壤有机质 (OM)、N、P、K、Ca 和 Mg（NPK 肥料没有显着增加 OM、Ca 和 Mg）、生长、产量、矿物质、蛋白质、灰分、碳水化合物和粘液与对照相比，秋葵果实的含量。与 NPK 肥料相比，有机肥料提高了秋葵产量。2018年秋葵生长和产量参数较2017年显着提高。2018年对照、兔粪、牛粪、家禽粪、绿肥、猪粪和氮磷钾肥使秋葵的荚果产量分别提高9.7%、35.3%、57.9% 、36.2%、39.2%、45.5%和3.2%，分别与2017年同处理相比。家禽粪便显着提高了秋葵的植物生长、产量、矿物质和近似成分，因为其土壤化学性质高，这可能与其最低的 C:N 比、木质素和木质素:N 比有关。结果还表明，在高强度降雨期间生长的秋葵产量较高，但除粘液含量外质量下降。因此，在中等降雨量下用家禽粪便种植秋葵将增强果实的健康益处，但是，建议那些希望在高降雨量期间种植其粘液成分的人。结果还表明，在高强度降雨期间生长的秋葵产量较高，但除粘液含量外质量下降。因此，在中等降雨量下用家禽粪便种植秋葵将增强果实的健康益处，但是，建议那些希望在高降雨量期间种植其粘液成分的人。结果还表明，在高强度降雨期间生长的秋葵产量较高，但除粘液含量外质量下降。因此，在中等降雨量下用家禽粪便种植秋葵将增强果实的健康益处，但是，建议在高降雨量期间种植含有粘液的秋葵。
