Implantação de lavoura de coffea arabica l. Com mudas produzidas em tubete e em saquinho

Abstract

The choice of seedlings to be implanted in the coffee plantation is of great importance for the producer, since it influences the formation phase of a healthy coffee plantation and consequently with good productivity. Therefore, the objective of this work was to evaluate the vegetative, productive and qualitative parameters, evaluating the physical classification of coffee according to seedlings produced in different containers used in the implantation of the crop. The experiment was implemented in 2018 at the Bordin Farm, located in Monte Carmelo – Minas Gerais. A cultivar used in the experimental area was the IPR 100, in a rainfed system. A randomized block design was used, with eight blocks and three treatments, as follows: T1 - Seedlings planted with a polyethylene bag containing 84 holes; T2 - Seedlings planted with the removal of the polyethylene bag containing 84 holes and T3 - Seedlings produced in tubes. The treatments were arranged in four planting rows, containing two blocks per coffee row. The evaluations of the growth parameters were carried out monthly from May 2018 to April 2020, analyzing the height, stem diameter and crown diameter of the plants. In June 2020, the first crop of the crop was harvested, evaluating productivity (60 kg ha-1 processed bags), grain classification, regarding grain size and shape, and maturation percentage. There was no influence of the types of seedlings used in the implantation of the crop in the growth of the coffee tree, productivity and physical analysis of the grains. As for maturation, the treatments showed no significant difference between them. The plants showed an average growth rate of 4.71 cm month-1 , 6.16 cm month-1 and 1.64 mm month-1 , respectively, for height, crown diameter and stem of the coffee trees. The average productivity of the first crop of the crop was 37.7 bags ha-1 .
