Abstract
ABSTRACT Adequate mineral fertilization and staking are necessary to obtain good productivity in yam cultivation. The objective of this study was to determine the increase in yield and quality of yams subjected to nitrogen doses and staking methods. This study was carried out under field conditions using a randomized block design in a 5 × 3 factorial scheme, with five nitrogen doses (0, 50, 100, 150 and 200 kg ha-1) and three staking methods (wire trellises, single staking, and without staking) with four replicates. Nitrogen doses were applied in topdressing, and split into equal parts at 60 and 90 days after seed tuber planting. Tuber length and weight, starch and leaf nitrogen concentrations, and total and marketable yields were determined. Staking promoted higher total yield, mass, length, and leaf nitrogen concentration, but no changes were observed in starch concentration among the staking methods. Commercial productivity was higher with single staking. Planting yam with staking and a nitrogen dose of 120.70 kg ha-1 is recommended to promote maximum productivity.
Highlights
Yam (Dioscorea spp.) cultivation in Brazil has great socioeconomic importance because of its use in human consumption and profitability
The most widely cultivated species in the Northeast Region are yellow yam (Dioscorea cayennensis Lam.) and water yam (Dioscorea alata L.) (Lovera et al, 2020), both of which contribute to the economic development of the Paraíba, Pernambuco, Sergipe, Alagoas, Bahia, and Maranhão states, because of their participation in farmers’ income and local commerce (Brito et al, 2011)
Single staking and wire trellises are the most frequently used staking methods during yam cultivation in the Northeast Region (Oliveira et al, 2015), because of the following two reasons: the cost and the traditional areas for planting yams being located in the vicinity of the Atlantic Forest
Summary
Yam (Dioscorea spp.) cultivation in Brazil has great socioeconomic importance because of its use in human consumption and profitability. The most widely cultivated species in the Northeast Region are yellow yam (Dioscorea cayennensis Lam.) and water yam (Dioscorea alata L.) (Lovera et al, 2020), both of which contribute to the economic development of the Paraíba, Pernambuco, Sergipe, Alagoas, Bahia, and Maranhão states, because of their participation in farmers’ income and local commerce (Brito et al, 2011). Research aimed at technologies that favor cultivation and nutritional management is essential to increase the productivity of this crop (Oliveira et al, 2015). Single staking and wire trellises are the most frequently used staking methods during yam cultivation in the Northeast Region (Oliveira et al, 2015), because of the following two reasons: the cost and the traditional areas for planting yams being located in the vicinity of the Atlantic Forest. The producer chooses to use wood obtained from the forest to carry out the single staking of the plants, damaging local biodiversity when exploited constantly
