Efeito da calagem e de diversas adubações na batata-doce e no cará, em solos de baixa fertilidade, derivados do arenito Botucatu

Abstract: No presente trabalho são relatadas duas experiências realizadas em Santa Rita do Passa-Quatro, para estudar o efeito da colagem e de algumas adubações sôbre a batata-doce (Ipomoea batatas Lam) e o cará (Dioscorea alata L.), em solos pobres, derivados do arenito Botucatu. A primeira, conduzida por cinco anos consecutivos, foi instalada nas proximidades de uma baixada com solo arenoso, ácido, tendo elevado teor de matéria orgânico. Em números relativos, as respostas à colagem e à adubação com NPK foram enormes. … Show more

“…Acid soils with Al saturation greater than 20% seriously limit sweet potato yield (Ila'ava et al, 2000). In these soils, sweet potato responds positively to liming (Camargo et al, 1962;Santos Junior et al, 2020), with increases in storage root yield up to a 60% soil base saturation (Figures 3a, b). Therefore, liming is considered a minimum practice of soil fertility management to improve sweet potato yield (Santos Junior et al, 2020).…”

“…Therefore, liming is considered a minimum practice of soil fertility management to improve sweet potato yield (Santos Junior et al, 2020). Camargo et al (1962) and the equation that relates soil pH with soil base saturation (BS) (pH=3.66+0.027BS) proposed by Quaggio et al (1982).…”

“…Bonnet et al (7) found that sweet potato responded to liming on two red acid soils (Ultisols) of Puerto Rico. However, Camargo et al (9) in Brazil found no response of sweet potatoes to liming on sandy acid soils. Lugo et al (10) reported a yield increase of 15% due to liming Corozal soil, an Aquic Tropudults of Puerto Rico.…”
