Alley Cropping and Organic Compost: An Efficient and Sustainable Agro-Ecological Strategy for Improving Turmeric (Curcuma longa L.) Growth and Attributes

Alley cropping is a sustainable agriculture approach that improves ecosystem services while also promoting biodiversity. The current study was conducted over two seasons, 2019/2020 and 2020/2021, to examine the impact of leucaena–turmeric alley organic compost addition as agroforestry systems on growth, yield characteristics turmeric crop. included four treatments: control (turmeric sole crop), cultivated between leucaena trees pruned at 1 m height, 1.5 height unpruned trees. Meanwhile, rates were (received recommended NPK) 17 34 m3 ha−1. This study’s results showed growing in rows resulted maximum plant production characteristics. Minimum growth parameters recorded with plants grown those where In addition, ha−1 led attributes Compost shown be an effective agro-ecological system for increasing output quality. demonstrated importance selecting appropriate crop–tree combination this it discovered leguminous significantly contributed improving fertility nutrient availability, which turn improved turmeric, particularly leaf-area index its content, are beneficial rhizome curcumin content.
