Evaluation of doses and acidity corrector products in biometrics characteristics in production of passion fruit seedlings - DOI: 10.4025/actasciagron.v31i4.529

Abstract

The search for new agricultural products is of utmost importance for a sustainable and ecologically viable agriculture. The present work was conducted in the seedling nursery of the Fruticulture Sector of the Federal University of Lavras, Lavras, Minas Gerais State. The experimental delineation was randomized blocks in a 3 x 4 factorial scheme with 3 products, 4 doses e 3 repetitions. The doses were calculated in order to reach the established saturation, according to the concentration of each product. The doses were: zero, half, full and the double the recommended dose. Incubation was carried out for silicon and limestone, while Lithothamnium, due its quick release, only was incorporated to the ground. The evaluated characteristics were: growth of the aerial part (mm), size of the root system (mm), number of leaves, dry matter of the aerial part (mg), dry matter of the root system (mg) and total dry matter (mg). The three products in question provided quality seedlings, being that 1.4 times the recommended dose was the best one for the formation of passion fruit seedlings.
