Impact of shade management and agronomic factors such as soil types, fertigation levels and intervals on ginger growth characteristics

Abstract

Effective shade management, soil practices, and fertigation techniques are critical for optimizing ginger growth, yield, and quality. Moderate shade levels (20–40%) improve photosynthesis and dry matter production, while excessive shade heightens disease risk and lowers quality. Customizing shade, water supply, and light quality to specific cultivars and environments, along with intercropping and protective structures, fosters favorable microclimates. Soil management, including mulching and amendments like biochar and vermicompost, enhances plant growth, soil health, and nutrient availability. Drip fertigation, applying 100–125% of recommended nutrients, ensures consistent uptake, balanced growth, and high yields. Frequent fertigation, enriched with microbial consortia, optimizes plant physiology and reduces stress in controlled environments, highlighting the value of sustainable cultivation practices.
