Marine calcium application on ‘Palmer’ mango production

ABSTRACT Considering the growing demand for mango to meet national and international market competitiveness among producing markets, use of new products management techniques that improve potential production in irrigated areas Brazilian northeast can be an important tool sustainability its cultivation. In this context, objective present study was evaluate effect doses periods application calcium from Lithothamnium seaweed via fertigation, two cycles ‘Palmer’ semiarid region. The experiment conducted at Saúde farm, located Projeto Senador Nilo Coelho N-09, city Petrolina, PE, Brazil. experimental design randomized blocks, a 5 × 4 2 factorial scheme, corresponding five fertigation (0, 5, 10, 15 20 L ha-1), four (30, 60, 90 120 days after flowering) cycles, with three totaling plots. variables evaluated were: number marketable fruits parthenocarpic per plant, average weight fruits, fruit production. Application 12 plant promotes 20% increase yield Sub-middle São Francisco Valley. Calcium should applied beginning up 30 flowering on varies according cycles.
