Sweet potatoes are being planted on mounds, ridges or flat beds in the meantime good soil aeration can be required for storage root initiation, development and increased yields, subsequently the peak of the mound or ridge to be used is essential.
The mounds and ridges to be used should guarantee good drainage, making it simpler to harvest the mature roots, particularly when harvesting is completed in a piecemeal trend as is commonly the case with candy potatoes.
Whether or not mounds or ridges or beds are used, their sizes at all times varies amongst places, often primarily based on what is definitely most sensible for farmers in that space.
In scenario the place tractors or ox-ploughs can be found, ridges are usually most well-liked, however ridges, mounds and beds might all be ready manually.
Land preparation for planting is the one most labour-intensive half of candy potato manufacturing. In households the place there are labour shortages, candy potato could also be planted in flat beds, though this usually ends in decrease yields than when ridges or mounds are used.

Sweet potato vine cuttings or sprouts, a minimum of 3 nodes (about 20-30 cm) lengthy are often planted at a spacing of 25-30cm between crops and 60-100 cm between ridges, though farmers like to experiment with completely different spacing’s and will often plant varieties with trailing vines wider aside than these with semi-erect or erect vines.
The place candy potato is grown on mounds, farmers often plant 3 vines per mound with some area between the vines.
At a spacing of 1 m x 1 m between mounds, 30,000 cuttings are required per hectare if 3 cuttings per mound are used. Whereas on ridges 33,333 cuttings are required to plant a hectare at a spacing of 30 cm between crops and 1 m between ridges.
Adjustment of spacing can be utilized to management storage root measurement, with nearer spacing producing a better proportion of smaller candy potato roots, that are most well-liked by some markets.
To plant, a stick, machete or hoe is used to make a gap that almost all of the reducing (a minimum of two nodes ought to be below the soil to improve institution and enhance the quantity of roots that kind) is positioned into the soil, leaving solely the tip uncovered.
The soil is firmed into place to guarantee good contact between nodes and the soil. Typically decrease leaves are eliminated earlier than planting, however this isn’t essential.
Farmers typically maintain cuttings for a day or two in a cool, shady place to encourage root initiation prior to planting. In lots of locations farmers historically use two vine cuttings per planting gap, nevertheless this requires loads of further planting supplies, and extensionists suggest utilizing only one reducing per gap and then hole filling any crops that fail to set up.
On mounds, the three cuttings are planted in direction of the highest of the mound however equidistant from one another in a triangle configuration. On ridges, the cuttings are planted both vertically or at a slant alongside the highest of the ridge on the required spacing.
Sweet potato is commonly planted after the precedence cereal crops and different vital money crops, and when adequate planting supplies have been generated by the rains.
Nevertheless, in areas with a brief wet season these delays in planting can find yourself exposing the candy potato crop to drought durations and weevil harm, considerably decreasing potential yields.
