Abstract

ABSTRACT Intensive use of synthetic fertilisers in fruit crops has resulted in negative impacts on the environment and biodiversity. The use of organic nutrient regimes is regarded as an alternative solution for agricultural sustainability and human health. This case study investigated effects of organic nutrient regimes on soil properties and nutrient status of leaves of Khasi mandarin (Citrus reticulata Blanco) at Mizoram University, Aizawl, India. The experiment included 13 treatments: T1: farm yard manure (FYM); T2: vermicompost (VC); T3: pig manure (PM); T4: mustard oil cake (MOC); T5: FYM +Azospirillum + phosphate solubilising bacteria (PSB) + potash solubilising bacteria (KSB); T6: VC + Azospirillum + PSB + KSB; T7: PM + Azospirillum + PSB + KSB; T8: MOC + Azospirillum + PSB + KSB; T9: FYM + Azotobacter + arbuscular mycorrhizal fungi (AMF) + KSB; T10: VC + Azotobacter + AMF + KSB; T11: PM + Azotobacter + AMF + KSB; T12: MOC + Azotobacter + AMF + KSB and T13: Control (RDF). The results demonstrated that the application of organic amendments and bio-fertilisers enhanced leaf nutrient status as well soil health parameters. The highest concentrations of total N, K, Fe and Zn in the leaves and concentrations of organic, inorganic and total carbon, total N, available N, K, Fe, Mn, Cu and Zn and abundance of bacteria, fungi and actinomycetes in the soil were recorded with T10. Thus, T10 was considered the most effective in terms of increasing leaf nutrient status and soil physico-chemical properties in the Khasi mandarin production system.

富含生物肥料的有机改良剂对红橘（Citrus reticulata Blanco）叶片营养状况和土壤性质的影响

摘要：水果作物中大量使用合成肥料对环境和生物多样性产生了负面影响。有机营养制度的使用被视为农业可持续性和人类健康的替代解决方案。本案例研究调查了有机营养制度对印度艾扎沃米佐拉姆大学的Khasi柑橘（Citrus reticulata Blanco）土壤性质和叶片营养状况的影响。试验包括13个处理：T1：农家肥（FYM）；T2：蚯蚓堆肥（VC）；T3：猪粪（PM）；T4：芥末油饼（MOC）；T5：FYM+偶氮螺菌 + 磷酸盐溶解菌 + 钾溶解菌（KSB）；T6:VC + 偶氮螺菌属 + PSB + KSB；T7:PM + 偶氮螺菌属 + PSB + KSB；T8:MOC + 偶氮螺菌属 + PSB + KSB；T9： FYM + 固氮菌 + 丛枝菌根真菌 + KSB；T10:VC + 固氮菌 + AMF + KSB；T11:PM + 固氮菌 + AMF + KSB；T12:MOC + 固氮菌 + AMF + KSB和T13：控制（RDF）。结果表明，施用有机改良剂和生物肥料提高了叶片营养状况和土壤健康参数。用T10记录了叶片中总氮、钾、铁、锌的最高浓度，以及土壤中有机、无机、总碳、总氮、有效氮、K、铁、锰、铜、锌的浓度以及细菌、真菌和放线菌的丰度。因此，T10被认为是提高喀什柑橘生产系统叶片营养状况和土壤理化性质的最有效方法。

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.
