Organic cultivation of Northern Garlic Allium tuberosum as a function of biofertilizer doses and ground covers

Abstract

The use of biofertilizer and soil cover is a low-cost alternative in the management of weeds, pests and diseases. The objective of this work was to evaluate the organic cultivation of Northern garlic Allium tuberosum as a function of biofertilizer doses and soil cover. The experiment was carried out in two stages, the first was in randomized blocks with four replications and five treatments, composed of four concentrations of biofertilizers and one without application. Said concentrations were 25%, 50%, 75% and 100%. The second experiment was in randomized blocks with five replications and four treatments, three soil covers and one without cover, described as: Mulching (plastic), jambeiro leaves and garden grass. The number of commercial, senescent and total leaves were evaluated; sheet length; tiller number and fresh and dry mass. The maximum production of number of commercial leaves was obtained with the application of biofertilizer at a concentration of 65.28%, which provided 15.20 commercial leaves. The use of ground cover reduces the level of weed infestation and provides greater increases in leaf length, production of fresh and dry mass, which are, the main quality characteristics of Northern garlic.
