The sweet potato (Ipomoea batatas (l.) Lam.) Lam) is a plant that produces tuberous root belonging to the family convolvulácea explored in practically all states of Brazil. The objective of this work was to select genotypes of the sweet potato as the efficiency of phosphorus use in cerrado soils with high and low availability of this nutrient. Were evaluated nine genotypes of sweet potato coming from the germplasm bank from the Federal University of the Tocantins, Brazil. The experimental design was in randomized block design with three replications being nine genotypes grown in two environments with low and high phosphorus availability, using doses of phosphorus fertilization from 20 and 120 kg ha-1 P2O5, applied at planting. To select genotypes suitable for environments proposed was used methodology for selection of the efficient use and response to phosphorus fertilization (efficiency and response). Genotype Amanda was classified as efficient and responsive, Barbara, Julia, Marcela and Carolina Vitoria as efficient, but not responsive and Livia, Duda, Ana Clara and Beatriz were classified as non-efficient, responsive but the absorption and utilization of phosphorus.

Planting Method

Sweet potato (Ipomoea batatas L.) is the most grown storage root crop in Eswatini. However, its storage root yield is low among smallholder farmers partly due to use of inappropriate varieties and agronomic practices such as planting method. Thus, a field experiment was conducted at the University of Eswatini, Faculty of Agriculture, Luyengo, during 2019/2020 cropping season to determine the effects of planting method on growth and yield of the three sweet potato varieties. Two planting methods, namely horizontal and vertical; and three sweet potato varieties, namely Kenya-white, Ligwalagwala and Lamngititi were evaluated in a factorial arrangement in randomized complete block design in three replications. Results showed non-significant difference between the planting methods in most growth and yield parameters recorded for the sweet potato varieties. However, the vertical method of planting had relatively higher vine length, number of branches, mass of storage roots and storage root yield than the horizontal method. On the other hand, there were significant (P<0.05) differences among the sweet potato varieties for most of parameters recorded. The sweet potato variety Ligwalagwala had the highest vine length, number of storage roots per plant (6.47), mass of storage roots per plant (1137 g) and storage root yield (12.01 tonnes/ha). Thus, either horizontal or vertical method of planting and variety Ligwalagwala can be used to increase the productivity of sweet potato in the study area.
