Influence of planting density on pineapple cv. Smooth Cayenne

Abstract

The experiment was carried out at the Research and Extension Center for Tropical Fruit (CEPEX), on the microregion of vale do Rio Uruguai at Porto Lucena, RS, Brazil. The objective of the study was the evaluation of five different density plantings on pineapple culture. The treatments consisted of 90 x 40 x 25, 90 x 40 x 30, 90 x 40 x 35,90 x 40 x 40, and 90 x 40 x 45, respectively 61,540, 51,280, 43,955, 38,460, and 34,190 plants per hectare. The highest density planting had a yield of 44,510 fruits, significantly higher than those from the other treatments, and a yield of 56.63 ton/ha. The average fruit weight was not affected by high density. The total soluble solids were not affected by the treatments, but the high density planting increased the titratable acidity.
