Plantio irrigado de bananeiras resistentes à sigatoka-negra consorciado com culturas anuais

Abstract

This work was carried out at Experimental Farm of the Universidade Estadual de Montes Claros, Campus Janaúba-MG, with the purpose of evaluating the irrigated planting of banana trees resistant to black sigatoka intercropped with annual crops in the north of Minas Gerais. The experimental design was in randomized blocks with subdivided plots, in 3 x 5, having in the plot the three banana cultivars ´Pacovan Ken`, ´Caipira` and ´Thap Maeo`, forming the main crop, and five treatments, concerning to intercalated cultures, with three replications. The intercropping cultures were ‘Perola’ bean, ‘Dardo’ okra, ‘Crimson sweet’ watermelon and ‘Caupi’ bean, besides control (without crops). Each plot was composed by six useful banana trees. The intercroppings occupied the inter-rows of the banana plants, with and without the irrigation line. The banana planting was performed on April 4th 2006 and the intercroppings on April 5th 2006. The spacing applied was 3.0 m x 2.0 m, with microsprinkler irrigation. The vegetative and reproductive characteristics were evaluated. There was no significant effect of the intercropping on the banana cultivars, except for the number of planting days to flowering and the number of planting days to harvest. The ´Pacovan Ken` banana showed greatest height, and the ‘Caipira’ the smallest one, independent of the used intercropping. The ´Thap Maeo` showed shorter production cycle than the ´Caipira`. The ´Thap Maeo` presented yield of 28,6 t.ha-1, ´Pacovan Ken` 27,0 t.ha-1 and ´Caipira`, 24,8 t.ha -1.
