Sweet potato crops take up large amounts of nutrients, especially nitrogen. In low-fertility
soils, the addition of nitrogen (N) increases the sweet potato yield. Green manure may be an …

Estimating genetic parameters is an essential procedure to define strategies for breeding
and selection of higher yielding genotypes. The use of a selection index can assist in …

To assess the effect of pure castor meal and a mixture of castor meal with ground
hydrothermalized phonolite rock (CM+ HP mixture) in providing nutrients, particularly N and …

The excess of nitrogen (N) causes the overgrowth of sweet potato foliage, increasing the self-
shading and reducing the root yield. Therefore, a combined N and paclobutrazol (PBZ) …

The objective was the genetic selection of cassava (Manihot esculenta crantz) to formation
of groups. Initially, 23 quantitative variables from 28 genotypes were used. After principal …

The performance of different genotypes is different according to the environment and
production process employed, knowing this behavior is fundamental to obtain good …

Chicken manure is accessible to family farmers, is produced in large volumes, and has a low
cost. Therefore, it can be an alternative to increase the productivity of sweet potatoes …
