Prueba de la eficiencia del fertilizante orgánico biofungi en el rendimiento del cultivo de Brassica oleracea L, var. Avenger (Brócoli).

Abstract

This research proposes: to evaluate the effectiviness of organic fertilizar Biofungi in three doses and two periods of application in crop yield of brócoli (Brassica oleracea L, var.. Avenger), in the Gatazo Zambrano Community, Cajabamba parish; with a Design Randomized Complete Blocks in bifactorial under seven treatments and four replications including absolute control for comparison, the application of organic fertilizar Biofungi began at 8 days after trasplantation and ended a week before harvest. Foliar fertilization with organic Biofungi shows positive effects on the crop, obtaining greater plant height with 48.05 cm, rapid appearance of the pellet to 67.85 days after transplantation, the greater weight of 668.75 g pelleted, larger diameter 17.25 cm pellet with better performance per net plot and 14.04 kg per hectare with 28.90 tm/ha, for the agroindustrial process, applying Biofungi in doses of 3 cc/l (T6). At the end of the treatments economically, it is determinet thet the application of Biofingi in doses of 3 cc/l every 7 days (T3), has the highest cost varies with $ 970.00/ha. The treatment had the highest marginal rate of return was the application Biofungi average dose of 3 cc/l every 14 days (T6) with 1675,31 %, indicating that for every dollar invested, is recovered further dollar invested and earns $ 16,75 The Biofungi is a liquid fertilizer which contains iónfosfito-potassium-copper, more plant extracts and vegetable fatty acids. It is an ecological input.

Key words: organic fertilizer, broccoli crop, plant extracts
