Resumo
O experimento teve como objetivo avaliar a distribuição das raízes do maracujazeiro-doce (Passiflora alata Dryand), cultivado em Nitossolo Vermelho, sob adubação química e orgânica, em Botucatu-SP. Foram utilizadas plantas com 19 meses de idade, em produção, conduzidas em latada e com irrigação. Os tratamentos com fertilizantes químicos e esterco de curral curtido foram os seguintes: T1 (400 g de sulfato de amônia), T2 (2,5kg de esterco), T3 (5,0kg de esterco), T4 (7,5kg de esterco) e T5 (10,0kg de esterco), acrescidos de 200g de termofosfato, 137g de cloreto de potássio e 2,0kg de calcário por planta, em todos os tratamentos, parcelados em duas aplicações. Foram empregadas 3 plantas por tratamento, sendo retiradas quatro amostras de cada uma, a 0-20 e 20-40cm de profundidade e distância do tronco. Os resultados evidenciaram que não houve diferenças significativas entre os tratamentos para massa seca das raízes. em todos os tratamentos, houve concentração das raízes a 0-20cm de distância do tronco. Nas parcelas com adubo orgânico, houve melhor distribuição das raízes em profundidade.
The experiment had as purpose to evaluate the fragant granadilla (Passiflora alata Dryand) roots distribution, cultivated in Nitossolo Vermelho, under chemical and organic fertilization, in Botucatu/SP. It was utilized plants with 19 months, in production, driven in latada and with irrigation. The treatments with fertilizers chemical and manure were: T1 (400g ammonium sulfate), T2 (2,5kg of manure), T3 (5,0kg of manure), T4 (7,5kg of manure) e T5 (10,0kg of manure), enhanced with 200g of termophospate, 137g of potassium chloride and 2,0kg of calcareous for plant, parceled in two applications. It was evaluated 3 plants by treatment, with four replications of each one, at 0-20 and 20-40cm of deep and distance of the stem. The results showed that there were no significant differences among the treatments for dry weight of the roots. In all the treatments there was concentration of the roots at 0-20cm distance of the stem. The treatments with organic fertilizer had the best deep roots distribution.
