FERTILIZANTE ORGANOMINERAL ASSOCIADO A MICRORGANISMOS EFICIENTES NO CULTIVO DE RÚCULA

Abstract

The arugula is a small annual vegetable, averaging 15 to 20 cm in size, with green, jagged leaves belonging to the family Brasicaceae. This vegetable has great economic importance, grows all year round and adapts best to mild temperatures, early reproductive stages at high temperatures. This work aimed to evaluate the effects of doses of organomineral fertilizer associated with the application of efficient microorganisms on the production of arugula. The study was conducted in a protected environment at UEG, Campus Sudoeste, and University Unit of Santa Helena. The experimental design was in causalized blocks (CBD) in a 5x2 factorial scheme (5 doses of organomineral fertilizer: 45, 90, 135, 180, 225 kg ha-1 of P2O5; and presence or absence of efficient microorganisms). The parameters evaluated were plant height (PA), stem diameter (CD), root length (RC), number of leaves (NF), aboveground fresh mass (MFPA), root fresh mass (MFR), total soluble solids (STT), pH in water (pH) and total titrated acidity (ATT), obtained through the evaluation of the organomineral fertilizer, evaluated in the production of arugula, the data were submitted to the analysis of variance associated with the F test at 5% probability. The fertilizer doses evaluated had effects only on (CD) with a quadratic behavior, observing increasing values until the optimum dose of 139.4 kg ha-1 being the point that reflected in the greatest diameter of the arugula stem, with a value of 3.68 mm. Plant height and root length showed linear increasing behavior and pH in water linear decreasing as a function of the phosphorus dose. The total titratable acidity showed a quadratic behavior, the lowest acidity being found at a dose of 137.5 kg ha -1
