Crescimento e produtividade da bananeira cv. Grande Naine sob diferentes combinações de nitrato de cálcio e ureia

Abstract: Growth and yield of banana crop under different combinations of calcium nitrate and ureaThe use of nitrogen sources through fertigation requires improved techniques so that farmers may obtain maximum economic benefit combined with lower soil impact. The objective of this work was to evaluate different combinations of two nitrogen sources applied by fertigation on the growth and yield of banana cv. Grand Naine during the first, second and third production cycles. The experiment was arranged in a randomized bloc… Show more

“…In addition, it is worth emphasizing the influence of residues of banana crop on the nutrition of the crop, since the banana residues left on the soil as mulch, after harvest, sometimes guarantee yields equal to those of other cover crops, due to the supply of N (Muliele et al, 2015). Absolute yield values in the conventional treatment are also consistent with studies that used similar amounts of N (Alves et al, 2010).…”

“…O nitrato de potássio ocasionou maior concentração média de nitrato na solução do solo considerando-se as profundidades 0,30 e 0,60 m em relação à ureia (Tabelas 2). Este resultado é justificado pelo fato de o ion nitrato (NO 3 ) de carga negativa ser diretamente liberado na solução do solo assim que o nitrato de potássio dissolvido na água de irrigação entra no meio poroso, não sendo adsorvido pelas micelas, o que não ocorre no caso da ureia, que precisa passar por processos de hidrólise que resulta em ions de carga positiva (amônio) e que pode ser retido nas micelas e nitrificação para resultar no íon nitrato (Alves et al, 2010).…”
