Produção e qualidade de mudas de romãzeiras (Punica granatum L.) sob diferentes doses e tipos de biofertilizantes

Abstract

In Brazil, the cultivation of the pomegranate aroused interest in several fruit producers, mainly in the Northeast. The objective was to evaluate the production and quality of pomegranate seedlings under the effect of different doses of the Nov @ ® and Carbo-Organ ® biofertilizer. The experiment was conducted in a greenhouse belonging to the research group of the Federal Rural University of the Semi-Arid, using a randomized block design (DBC), in a 2x5 factorial scheme, two commercial biofertilizers (Nov @ ® and Carbo- Organ ®) with five doses - 0; 2; 4; 6 and 8 ml L-1), with four replicates and five plants per plot. At 70 days after sowing the characteristics were evaluated: shoot length (cm), root length (cm) and total length (cm); Number of leaves (Plant-1 unit); Lap diameter (mm); Dry mass of the aerial part (plant-1), root dry mass and total dry mass (gil-1), the Dickson quality index (Adimensional) was also evaluated. The use of the Nov @ e Carbo-Organ® biofertilizer at the doses of 6.0 and 8.0 mL L-1, respectively, favored higher growth and development of pomegranate seedlings.
