Quality index and Conilon coffee seedling growth under irrigation and hydroretentive

Abstract

The objective of this study was to evaluate the quality of Conilon coffee seedling, produce under different irrigation levels, with and without hydroretentive in bags and tubes. The experiments were conducted in the Federal Institute of Education, Science and Technology‘s nursery in the state of Espírito Santo, Alegre’s Campus. The experiments was set up in a split-plot design 4 x 2 x 2, plots of irrigation level of four depths (25; 40; 55 e 70% of ET0), in the subplots recipients in two levels (tube and bag) and in the split split plots in two levels (with and without hydroretentive), in a completely randomize design with four replications. At one hundred and forty days of age, was evaluated the following: plant height, stem diameter, leaf area, shoot and root dry matter, ratio of height/stem diameter, ratio of matter/root and the Dickson’s quality index. The seedlings grown in the bags showed higher development to the seedlings grown in tubes. For the seedlings grown in the bags in the depth 40% of ET0 is the best, being the depth 70% of the one the provided the best development of the seedling in tubetes. The presence of hydroretentive promote the best development of the seedlings produce in bags.
