Estudo da densidade de plantio em alho na região de Inconfidentes-MG

Abstract

The experiment was conducted in Inconfidentes, South of Minas Gerais, with the objective of evaluating the garlic planting density.The randomized block design, with four replicates, arranged in factorial scheme involving three interrow spacings (0.20, 0.25, 0.30m), and three interplant spacings (0.8; 0.10, 0.12m) in the double rows (0.10m), amounting to nine treatments in which the cultivar (Gigante Roxo do Espírito Santo) was utilized. The results showed that the largest spacings significantly influenced the evaluated characters and the obtained results allowed to verify smaller losses of dry matter mass of shoot and bulbs, less percentage of emptiness, with a reduction of up to 66% relative to the smaller spacings. There were growing responses to the total yield of plants and total mass of bulbs. For the character bulb mass loss, there was a significant interaction between the factors row spacing interplants and larger interplant spacings. Larger interplant spacings propiciated an increase of florões bulb (a head of garlic which is the largest in the classification scale) of about 11%. The best spacings among line using double rows were 0,30m interrow, corresponding to a population of 440 thousand plants.
