Influence of harvest time and cultivation sites on the productivity and quality of sweet potato

Abstract: Sweet potato is one of the most cultivated tuberous roots in tropical and subtropical regions permitting several ways of use. Despite its potential use, sweet potato has been little studied. We evaluated the performance of sweet potato roots, forage productivity and its silage at different harvesting times and cultivation environments and we identified the most superior clones under different soil and climatic conditions. Six sweet potato clones (BD-38, BD-45, BD-25, BD-31TO, BD-15 and BD-08) belonging to germ… Show more

“…Yield of sweet potato marketable roots can easily reach 45.4 t ha -1 (Andrade Júnior et al, 2009;Azevedo et al, 2014); however, in Vale do Jequitinhonha, this productivity is much lower. Thus, obtaining agronomically superior cultivars adapted to Vale do Jequitinhonha through genetic improvement can be an important strategy in the region and throughout Brazil.…”

“…Esta informação relevante demonstra que estes genótipos podem ser utilizados em cruzamentos, pois segundo Belete et al (2011), o cruzamento entre genótipos com maior divergência genética possibilita a obtenção de populações altamente segregantes, com maior probabilidade de encontrar genótipos transgressivos para múltiplas características. Além da dissimilaridade, para a escolha de genitores é importante que se tenha elevado desempenho per se, o que já foi confirmado para todos os genótipos em trabalhos anteriores (Gonçalves Neto et al, 2011;Viana et al, 2011;Andrade Júnior et al, 2012;Azevedo et al, 2014 Silva et al (2011) evidencia uma base genética restrita entre os genótipos avaliados. Os genótipos pertencentes à este grupo apresentam valores próximos para o teor de matéria seca e teor de sódio.…”
