Avaliação nutricional e qualidade de mudas de maracujá em resposta á adubação organomineral

Abstract

The production of passion fruit seedlings is a crucial step in fruit growing, as it determines the quality and future productivity of the crop. The choice of substrate, irrigation management and adequate nutrition are essential to guarantee the vigorous development of the seedlings. The objective of this work was to evaluate the nutritional condition and quality of Passiflora edulis seedlings using quality indices. The treatments were represented by a factorial of phosphorus application followed by FOL, FOG and FOL+FOG treatments with 30, 60, 90 and 120%, being arranged in a completely randomized design with thirteen treatments and four replications, in a double factorial arrangement with addition of an additional treatment (control – conventional system), (3(x)4)+1. At 45 days after transplanting, the following data and the relationship between shoot dry matter and root dry matter (RPAR) were collected to calculate the Dickson Development Index (DQI); relationship between shoot height and stem diameter (RAD): Total dry mass (MST) (g); Height (H)(cm); Neck diameter (DC)(cm); Shoot dry matter weight (PMSPA)(g); Root dry matter weight (PMSRA)(g); , It is. Phosphate fertilizer had a significant influence on all variables studied. Fertilization with organomineral fertilizers was more significant compared to conventional management (control)
