Dataset for: Rice-sweet-potato rotation system: Improving rice yields and profitability by utilizing irrigated rice schemes for off-season production of sweet-potato vines and roots

During the fallow periods, there is prolific re-growth of mixed weeds, grasses and shrubs which become part of local grazing pastures during the dry season. However, this re-grown vegetation also significantly increases the work required to prepare the land again for rice the next season.

A rotation of rice-sweetpotato-rice might ease field management for both crops, reduce the costs of rice production as well as provide early planting material for sweetpotato upland growing. A study was initiated in Agoro rice scheme during the 1st season of 2016 to determine the effect of sweetpotato-rice seed crop rotation on rice seed purity, sweetpotato pest and disease prevalence, sweetpotato root and vine yield, and the cost-benefit ratio of different rotation options for providing basic seed in a timely manner to sweetpotato vine multipliers.
