The objective of this study was to evaluate the effect of different irrigation depth on initial development of Coffea canephora seedlings. The study was carried out at the farm Perobas, in the municipality of Rio Bananal, Espírito Santo, Brazil. The experimental design was completely randomized, with five treatments, comprising different depths of irrigation, being: 5, 7.5, 10, 12.5 and 15 mm dia-1. At 55 days after planting the seedlings were evaluated for characteristics:stem diameter, plant height, dry mass of aerial part and dry mass of the root system. The stem diameter and dry mass of the root system presented an inverse behavior to the increase of the irrigation depth. The plant height and dry mass of aerial part presented an increasing effect in relation to the variation of the irrigation depth. The 5 mm dia-1 irrigation depth provides the best result for development in the initial stages of the root system of the seedlings, while the irrigation depth of 15 mm dia-1 favored a greater accumulation of dry mass of aerial part of the seedlings.

“…The quality of the cocoa seedlings used in the orchard formation is very important in its success, due to the perennial nature of the crop (Posse et al, 2018). One of the factors that greatly affect the growth and development of the seedlings is the adequate water supply (Ramos et al, 2015).…”

“…However, there is little information on the water demand of cocoa seedlings, which leads to the determination of irrigation depths based only on empirical criteria, by the nurserymen, thus making it difficult to manifest by changing their maximum genetic potential when taken to the field (Gruber, 2006;Ramos et al, 2015;Posse et al, 2018).…”

Due to the lack of information on the water demand of cocoa seedlings, empirical techniques have been used in the supply of water to the seedlings, potentializing losses in their growth and development. In this context, the present study aimed to determine the optimal irrigation depth for a good development of the genotype PS-1319 cocoa seedlings. The study took place at the Federal Institute of Espírito Santo-Campus Itapina, located in the Colatina, a city situated in the northwestern region of the state of Espírito Santo, Brazil, in an experimental greenhouse of the campus, between October 20 and December 15, 2017. The experiment was conducted in a completely randomized design (CRD) using 20 seedlings of the genotype PS-1319 cacao per treatment. The treatments consisted of daily applications of six irrigation depths, corresponding to 4, 6, 8, 10, 12 and 14 mm d-1, being evaluated their effects on the morphological parameters (leaf area; dry mass of the aerial part, dry mass of the root system and total dry mass; height of the aerial part and stem diameter) and the quality (Dickson quality index). The applied depths interfered, both in the development and the quality of the seedlings, with quadratic adjustments for the leaf area, dry mass of the aerial part and total dry mass, diameter and for the Dickson quality index. The best responses to the studied parameters were provided by the 8.33 mm d-1 depth, which is recommended as an ideal for production of genotype PS-1319 cacao seedlings.
