“…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 and a control (no manure/ inorganic fertilizer). Both the organic manures and NPK fertilizer were applied at the rate of 120 kg N ha −1 32 . This was equivalent to 800 kg ha −1 for NPK 15-15-15, 11.9 t ha −1 for rabbit manure, 5.5 t ha −1 for cow dung, 4.1 t ha −1 for poultry, 4.8 t ha −1 for green manure and 5.6 t ha −1 for pig manure.…”

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.

“…The efficiency of N may be related to the fact that this nutrient is a constituent of proteins, which act in the absorption of nutrients by plants, participates in various biological processes, such as photosynthesis, respiration, synthesis in general, multiplication, cellular differentiation; and increase in the production of vegetative and flower gems (Malavolta, 2002;Filgueira, 2008;Cardoso & Berni, 2012).…”

“…Okra responses to mineral and organic fertilization have been observed by several researchers (Oliveira et al, 2007;Omatoso & Shittu, 2007;Abd El-Kader et al, 2010;Cardoso & Berni, 2012). Mineral nutrition of vegetables can influence their development with subsequent effects on quality.…”

Okra, Abelmoschus esculentus (L.) Moench, is a vegetable with annual fruit native to hot regions of Africa, well adapted to the conditions of the Northeast and Southeast regions of Brazil, where it is widely used by small farmers. This study aimed to evaluate the effect of mineral and organic fertilization on the production and quality of okra fruits. The experiment was conducted in randomized block design, with three replicates and eleven treatments defined according to a Baconian matrix. Treatments consisted of doses of N (0, 100, 200 and 300 kg ha-1), P (0, 100, 200 and 300 kg ha-1) and K (0, 80, 160 and 240 kg ha-1), as well as absence and presence of organic compost (30 t ha-1). The following parameters were evaluated: plant height, stem diameter, number of leaves, production of fruits plant-1, number of fruits plant-1, fruit length and diameter and fruit quality (pH, soluble solids, titratable acidity, vitamin C and electrical conductivity). The crop is demanding in terms of K and N fertilizations, with increments of 15.8 and 36% in the mean number and diameter of fruits, respectively. Organic fertilization did not influence the vegetative growth of okra, but was beneficial to the production of fruits with higher vitamin C content, 52% higher than the contents found in fruits produced without such input.

“…O preço do quiabo, em 2014, foi de R$ 0,50 à R$ 4,00 por kg. O quiabo Dardo, nas condições regionais, em solo com ótimos níveis de fertilidade, produziu com uso de uréia (em cobertura) 36 frutos por planta e 31 frutos por planta, com uso de esterco de galinha (Cardoso & Berni, 2012), portanto, a produção parcial de 20 frutos por planta pode ser considerada adequada, tendo em vista que aqui foi até os 60 dias em média, enquanto no exemplo, o período produtivo foi de 105 dias. Caso fosse utilizada toda a área útil de cultivo protegido (90 m 2 ) com essa espécie, ter-se-ia o total de 180 plantas, que produziriam em 105 dias, aproximadamente, 95 kg.…”
