“…Oliveira et al [16], found for papaya 'Rubi INCAPER 511', also belonging to the 'Formosa' group, a DQI maximum value of 0.43, using a daily 12.66 mm irrigation depth. Seedlings that present higher DQI are more likely to survive when taken to the field due to their greater capacity of acclimation, favoring their development [23,24].…”

Performing an adequate irrigation management for the production of papaya seedlings is essential to obtain plants that express all their genetic potential. For this reason, this work aimed to evaluate the effect of different irrigation depths on the growth and quality of papaya type 'Tainung 01' seedlings. The study took place at the Federal Institute of Espírito Santo, Campus Itapina, located in the in Colatina, in the Northwest region of the State of Espírito Santo, Brazil. The experimental design was completely randomized with 25 repetitions for each treatment. The treatments consisted on the application of six irrigation depths: 4, 6, 8, 10, 12 and 14 mm d -1. The seedlings were evaluated at 65 days after planting for the following morphological characteristics: plant height, stem diameter, number of leaves, leaf area, dry mass of the aerial part, dry mass of the root system, total dry mass and Dickson quality index. The irrigation depth of 9.16 mm d -1 had a higher Dickson quality index attesting a higher quality of seedlings, being the most suitable for the production of papaya 'Tainung 01' seedlings.

“…In all the analyzed characteristics of the "Mel" papaya seedlings, there was a negative influence both for the deficit and the water excess generated by the smallest and largest irrigation depths, respectively. This fact was also observed in the production of papaya cultivars "Rubi INCAPER 511" [10], "Tainung 01" [11] and "Golden THB" [12].…”

“…For papaya, water management protocols have already been reported in the production of seedlings of the cultivars "Rubi INCAPER 511" [10], "Tainung 01" [11] and "Golden THB" [12]. However, the different degrees of tolerance to the reduction of water humidity are associated with the individual's adaptation, which refers to a level of resistance genetically determined [13] or induced by natural selection, being fundamental application of specific studies to new materials, such as "Mel" papaya tree, a hybrid cultivar belonging to the Formosa group, with great market potential, due to high productivity, small size, uniformly shaped fruits and highly sweet pulp [14].…”

Water management is considered one of the most prevalent factors in the production of quality seedlings in commercial crops. Despite the benefits provided, the technique is still little used by irrigating users, who, for the most part, do not adopt any criteria for water use. Thus, aiming at the rational use of water resources and increasing the productive potential of seedlings, the objective of this study was to evaluate the effect of different irrigation depths on the production of Formosa "Mel" papaya seedlings (Carica papaya L.). The experiment took place in a greenhouse, located at the Federal Institute of Espírito Santo, Campus Itapina, in Colatina, ES. The treatments consisted of six irrigation depths corresponding to 4, 6, 8, 10, 12 and 14 mm•day −1 adjusted in a completely randomized design, with 25 plants per treatment. The variables evaluated were: plant height, stem diameter, leaf area, dry mass of the aerial part, dry mass of the root system, total dry mass and Dickson's Quality index, 58 days after sowing in all experimental plots. At the end of the experiment, it was found that the 7.36 mm•d −1 irrigation depth provided better quality, in addition to lower water consumption, being the most recommended for the production of Formosa "Mel" papaya seedlings.

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.
