Garlic cultivars yield in Tietê region, São Paulo State, Brazil

The high cost of garlic seed and the refrigeration process may increase yield, but it is a barrier for small farmers who are responsible for the large Brazilian production. Therefore, research seeking low cost garlic seed, regionally made, and competition studies for yield between refrigerated and no refrigerated cultivars are fundamental. This work aimed to evaluate yield and bulb quality of four no refrigerated garlic varieties (Assaí 3702, Gigante de Curitibanos, Santa Catarina Branco and Santa Catarina Roxo) and the refrigerated type Jonas (storage at 4º C for 40 days). The field trial was carried out during March-September 2005, in Tietê, São Paulo State, Brazil, in a randomized block design with five replications. Jonas, without differ from Santa Catarina Roxo, Santa Catarina Branco, and Assaí 3702 produced higher yields (8.4; 7.6; 7.4 and 6.9 t.ha-1 respectively) and greater bulb weights (30.5; 27.0; 26.3 and 24.6 g respectively). For bulb diameter these four varieties were graded as type 4 (36-45mm), Gigante de Curitibanos was lower than Jonas concerning to yield and bulb mass.
