CLOVE-SEED SIZE AND HEALTH AND PLANT SPACING ON THE VIABILITY OF GARLIC CROPS

2021

ABSTRACT Garlic is a vegetable that has a high economic importance for Brazil. However, despite increases in garlic bulb production in the last years, Brazil is still dependent on imported garlic to meet the national demand. Thus, proper management practices and the use of virus-free clove-seeds are promising alternatives to ensure a high productivity and profitability. Thus, the objective of this work was to evaluate production characteristics and profitability of conventional and virus-free garlic crops as a function of different clove-seed sizes and plant spacings. Two experiments were conducted simultaneously, using virus-free and conventional garlic plants in Portalegre, state of Rio Grande do Norte, Brazil, in a randomized block experimental design, with four replications. The treatments were arranged in split-plot, with the clove-seed size (large and small) in the plots, and the spacing between plants (7.5, 10.0, 12.5, and 15.0 cm) in the subplots. The combination between the use of virus-free clove-seeds, large clove-seed size, and spacing of 12.5 cm between plants resulted in the highest commercial bulb yield and net income, R$ (BRL) 85,151.00 ha-1. The use of large clove-seeds and spacing of 7.5 cm between plants are recommended for conventional garlic crops.
