Características fitométricas de cultivares de amendoim adubado de cinza vegetal

Abstract

Vegetable ash has properties that influence soil correction.For this reason, the objective was to evaluate the phytometric characteristics of peanut fertilized with doses of vegetal ash. The experiment was carried out in a greenhouse at the Federal University of Mato Grosso, University Campus of Rondonópolis-MT in a soil classified as Red Latosol (EMBRAPA, 2013). A completely randomized design was used in a 2x6 factorial scheme with two amandox cultivars (IAC OL3 and IAC 503) with six doses of vegetable ash (0; 6; 12; 18; 24 and 30 g dm-3); and five replicates. Four evaluations were carried out in the period of 15 days and at the time of analysis the height, leaf number, chlorophyll index, stem diameter and pH (after incubation of the soil with ash for 20 days) were analyzed.Peanut cultivars generally presented higher growth and development results when fertilized with a dose of vegetal ash in the range of 24 to 30 g dm-3 and the pH was in the linear equation. In this way, the vegetable ash raises the pH and in the appropriate dose of gray provides better development in the culture of the peanut.
