Use biofertilizer of agronomic performance cultivars Allium ascalonicum in edafoclimatic conditions of the Brejo Paraibano-Brazil

Abstract

Allium ascalonicum originate from the Mediterranean, aliácea of great economic importance, due to its wide acceptance by the market characteristics as soft, sweet and pleasant taste. Currently it has expanded organic agriculture the cultivation of these species, with the use of organic fertilizer, which is responsible for development of the plant increasing productivity. Therefore, this study aimed to evaluate the use biofertilizer of agronomic performance cultivars A. ascalonicum in edafoclimatic conditions of the Brejo Paraibano-Brazil. The experiment was carried out on farmer Pitiá Areia-Paraiba-Brazil, which was soil preparation done, incorporated 30 kg ha-1 of manure, then sowing onions Shallot White and Brown plat spacing 0,20 x 0,10 m. After 15 days of cultivation the biofertilizer was applied (50% fresh manure and 50% water) at doses 0,0 and 3,0% in leaves of A. ascalonicum. Harvest was done to seventy after planting days, the fruits were transported to Seed Technology Laboratory at CCA/UFPB-Areia-Paraiba/Brazil, where the following evaluations were performed: bulb diameter, bulbils number per bulb, average bulb weight, dry matter bulb and productivity. The experimental design was completely randomized with four treatments (two biofertilizer doses of 0,0 and 3,0%), (two varieties Shallots White and Brown) and four replications. The data submitted to ANOVA, means were compared by Tukey test at 5%, SISVAR ®. The biofertilizer doses did not influence the evaluated characteristics, except dose of 3,0% that favored increased productivity of onions Shallots White and Brown.
