Avaliação do teor de massa seca do café arábica submetido a diferentes turnos de rega e doses de hidroabsorvente.

Abstract

The objective of this research was to evaluate the dry matter content in coffee tree assayed with different irrigation timings and waterabsorbent doses in the initial plant growing. The work was carried out at a greenhouse at CCA-UFES (Alegre-ES). Coffea arabica variety Bourbon was the choosen one and it was produced in 100 ml recipients with commercial substrate plus 0.5 g of waterabsorbent. When the plants were transplanted a experimental completely randomized design was set in a fatorial 4 x 4, waterabsorbent in four amounts: 0; 3,0; 6,0 and 9,0 grams per recipient and irrigation timings in four dates: 7, 14, 21 and 28 days, with 3 replications. The evaluated parameters were: dry matter in the canopy and radicular system 120 days after transplanting. It was observed that plants produced more dry matter with irrigation timing of 7 days and it was not observed significantly differences in the different levels of waterabsorbent.
