COELHO, EUGÊNIO FERREIRA et al. Mango crop under different drainage regimes in subhumid conditions. Rev. Bras. Frutic. [online]. 2002, vol.24, n.1, pp.96-100. ISSN 0100-2945.

The knowledge of mango crop drainage criteria is fundamental for drainage system planning and for prediction of crop behavior under different drainage levels. The objective of the work was to evaluate air-water status in a sand soil (sand loam) profile under different ground water depths for determination of drainage criteria for mango, Keitt variety. The experiment followed a fully randomized design with four treatments ground water depth regime at distances from drain of 3.5, 10.5 and 17.5 m and under no ground water) and five replications. Ground water depths and water content in the soil profile were monitored during raining seasons of three consecutive years (1997 ¾ 1999). There was no significant difference among crop yields from treatments. The differences among ground water depths from treatments were not enough to result different soil water conditions in these treatments. The Ground water at average depth of 1.0 m, with transient recharges reaching soil surface followed by immediate discharge was not enough to affect development and yield of mango.
