- Abstract
The research was conducted with the objective of verifying the grain size of irrigated and nonirrigated conilon coffee during four harvests, through the physical classification by sieves. The experiment was installed in the year of 2013 in the Instituto Federal do Espírito Santo (Federal Institute of Espírito Santo), in a subdivided-plots scheme 3 x 4, being the plots the factor irrigation management in three levels (irrigated with replacement of 100% of the crop evapotranspiration (ETc), irrigated with 50% of the ETc, and non-irrigated), and in the subplots, the harvest factor in 4 levels (2013, 2014, 2015, and 2016), in a randomized block design, with three replications. The percentage of grains retained in sieve 13 and above, mocha grains, and grains retained at the fund of the sieve set were evaluated. Irrigation had a positive influence on grain size. Plants irrigated with 100% of the ETc obtained 72.5% of grains retained in sieves 13 and higher, while plants without irrigation obtained 33.1%. In the 2013 and 2014 harvests, higher values of grains retained in sieves 13 and higher and lower bottom values, 76.1% and 7.5%, respectively, were observed.
