Optimizing Plant Spacing to Improve Growth and Yield of Sweet Potato (Ipomoea batatas L.) Under Low Soil Fertility Conditions
Sweet potato (Ipomoea batatas L.) is an important food crop in tropical regions, but its productivity remains low on infertile soils where suboptimal agronomic practices, including inappropriate plant spacing, restrict plant growth and tuber development. This study evaluated the effect of different plant spacing arrang...
