摘要
摘要以可持续的方式生产健康食品是农业面临的一大挑战。2017年和2018年雨季,在一块空地上进行了盆栽试验,研究了施用五香(T)堆肥叶和有机可生物降解(OBD+)配方肥料对秋葵生长、产量以及矿物质和生物活性化合物浓度的影响。处理包括四种施用率的堆肥山雀叶(0、10、20和30 g 10 kg−1土壤)和三种施用率有机可生物降解(OBD+)配方肥料(0、0和20 g 10 kg–1土壤),这三种肥料以四个重复的完全随机设计组合和排列。测定了秋葵的性能和品质参数。与对照相比,施用改良剂显著提高了秋葵的营养生长和产量参数,施用30 T+10 OBD+可获得最高的生长和产量值。施用有机改良剂显著减少了秋葵的开花结果天数。结果还表明,随着30 T+20 OBD+和30 T+10 OBD+的施用,秋葵果实中矿物质元素和生物活性化合物的浓度显著增加。因此,为了提高营养和产量,以及矿物元素和生物活性化合物的积累,30T+10 OBD+被认为是最适合在研究区种植秋葵的。
Effects of application of organic formulated fertiliser and composted Tithonia diversifolia leaves on the growth, yield and quality of okra
ABSTRACT The production of healthy food in a sustainable manner is a major challenge for agriculture. Pot experiments were conducted in an open field during the rainy season in 2017 and 2018 to study the effects of the application of composted leaves of Tithonia diversifolia (T) and organo-biodegradable (OBD+) formulated fertiliser on growth, yield and concentrations of minerals and bioactive compounds in okra. Treatments consisted of four application rates of composted Tithonia leaves (0, 10, 20 and 30 g 10 kg−1 soil) and three rates of organic-biodegradable (OBD+) formulated fertiliser (0, 10 and 20 g 10 kg−1 soil), which were combined and arranged in a complete randomised design with four replications. Performance and quality parameters of okra were measured. The application of the amendments significantly increased vegetative growth and yield parameters of okra, compared with the control, with the application of 30 T + 10 OBD+ resulting in the highest values for growth and yield. The number of days to flowering and fruiting of the okra was significantly reduced by the application of the organic amendments. The results also revealed that the concentrations of mineral elements and bioactive compounds in the okra fruits significantly increased with applications of 30 T + 20 OBD + and 30 T + 10 OBD +. Therefore, for improved vegetative and yield performance as well as accumulation of mineral elements and bioactive compounds, the application of 30 T + 10 OBD+ was considered as the most suitable for the cultivation of okra in the study area.
期刊介绍:
Biological Agriculture & Horticulture aims to act as the central focus for a wide range of studies into alternative systems of husbandry, and particularly the biological or organic approach to food production. The Journal publishes work of a sound scientific or economic nature related to any aspect of biological husbandry in agriculture, horticulture and forestry in both temperate and tropical conditions, including energy and water utilization, and environmental impact.
