Abstract
Yield and physical and chemical characteristics of 'Paluma' guava fruit were evaluated as a function of the harvest at different maturity stages, under influence of nitrogen and potassium fertilization, in Petrolina, State of Pernambuco, Brazil. Fertilizer rates were 67 kg N + 33 kg K2O, 133 kg N + 67 kg K2O, 200 kg N + 100 kg K2O and 267 kg N + 133 kg K2O per hectare. Fruits were evaluated at maturity stages 2, 3, 4 and 5, established according to peel color. Higher doses of N and K induced higher yields. Nevertheless, fertilization with 200 kg of N + 100 kg of K per hectare improved fruit quality, delaying ascorbic acid breakdown and conserving pulp firmness. Main changes took place at maturity stages 4 and 5, when the fruit should present ideal conditions for consumption, namely the increase on soluble solids and soluble sugars content.
O presente trabalho avaliou a produtividade e as características físicas e químicas dos frutos de goiabeira 'Paluma' em diferentes estádios de maturação, sob a influência de adubações nitrogenada e potássica, em Petrolina-PE. As plantas foram submetidas à aplicação de 67 kg N + 33 kg K2O, 133 kg N + 67 kg K2O, 200 kg N + 100 kg K2O and 267 kg N + 133 kg K2O por hectare, sendo os frutos avaliados nos estádios de maturação 2; 3; 4 e 5, caracterizados conforme a cor da casca. As maiores doses de N e K resultaram em maiores produtividades, mas as aplicações de 200 kg de N + 100 kg de K por hectare favoreceram a qualidade do fruto, resultando em menor degradação de ácido ascórbico e preservação da firmeza da polpa. As principais mudanças que ocorreram entre os estádios 4 e 5, quando o fruto apresentaria condições ideais para consumo, foram relativas ao acúmulo de sólidos solúveis e de açúcares solúveis.
