Resumen

HENRIQUE ZONTA, João et al. INFLUENCE OF DIFFERENTIRRIGATION FREQUENCIES AND HYDROABSORBENT DOSES ON THE INITIAL DEVELOPMENT OF CONILLON COFFEE (COFFEA CANEPHORA PIERRE). Idesia [online]. 2009, vol.27, n.3, pp.29-34. ISSN 0718-3429.  http://dx.doi.org/10.4067/S0718-34292009000300005.

Adequate irrigation management to supply water sufficient to meet crop needs will guarantee good results in coffee irrigation. Hydro absorbent polymers improve water use efficiency by reducing irregular availability of water for crops. In this context, the objective of this work was to evaluate the effect of different irrigation frequencies and hydro absorbent doses on the initial stage of development of conillon coffee (Coffea canephora Pierre). The experiment was conducted in greenhouse, in the Municipal District of Alegre - ES, using the species Coffea canephora Pierre, variety Conillon. Planting was carried out in 10-L containers filled with Dystrophic Red-Yellow Argisol. The treatments consisted of 4 hydro absorbent doses (0, 3, 6 and 9 g per container) and four different irrigation frequencies (7, 14, 21 and 28 days) in a complete randomized 4x4 factorial design with 4 repetitions. The following agronomic parameters were evaluated 150 days after seedling transplanting to containers: seedling height, stem diameter, fresh mass of aerial part, dry mass of aerial part, root fresh mass, root dry mass and leaf area. Irrigation at 7 day intervals and hydro absorbent at the dose of9 grams gave the best initial development of conillon coffee under the tested conditions.

Palabras clave : Coffea canephora Pierre; irrigation; development.
