Resumo: | The most efficient way to improve coffee production in the first years is through plant density increasing. This work was carried out at Iguatemi Experimental Farm of the State University of Maringá (UEM) aiming to evaluate the influence of plant density increase on coffee agronomic traits, as well as on fruit and grain yield. The experiment was implanted in October, 1997, using coffee (Coffea arabica L.) plants of ‘Iapar 59’ cultivar. The plant densities evaluated were 3,333; 5,000; 6,666; 10,000 and 20,000 plants per hectare. The experimental design was in randomized blocks with three replications. The agronomic traits evaluated were plant height, leaf area, stem diameter, plant top diameter and number of plagiotropic ramification. Coffee fruits volume and weight, as well as grain yield per area and per plant, were also evaluated. The results indicated that plant populations near 14,000 plants per hectare showed better results in developing the characteristics evaluated; however, the higher production per plant was achieved with the density of 10,000 plants per hectare. The grain yield with plant density increase had linear response in the first year and quadratic response in the second. The highest production per area was achieved with plant populations of 20,000 plants per hectare in the first year and near 15,000 plants per hectare in the second year. |

Neste contexto, foi conduzido experimento na Fazenda Experimental de Iguatemi, pertencente à Universidade Estadual de Maringá (UEM), com objetivo de avaliar a influência do aumento na densidade das plantas sobre as características agronômicas e de produção de frutos e grãos de café. As mudas de cafeeiro (Coffea arabica L.) da cultivar ‘Iapar 59’ foram plantadas em outubro de 1997, utilizando-se uma muda por cova nas densidades de 3.333, 5.000, 6.666, 10.000 e 20.000 plantas ha-1. O delineamento experimental utilizado foi em blocos casualizados, com três repetições. As características agronômicas avaliadas foram altura de planta, área média da folha, diâmetro do caule, diâmetro da copa e número de ramos plagiotrópicos. Também foram avaliados o volume e a massa de café cereja, bem como a produção de café despolpado e beneficiado por área e por planta. Os resultados obtidos indicaram que populações próximas de 14.000 plantas ha-1 foram as que apresentaram os melhores resultados nas características de crescimento avaliadas. Contudo, a maior produção por planta foi alcançada com 10.000 plantas ha-1. A produção de grãos apresentou resposta linear crescente, no primeiro ano, e quadrática, no segundo ano, com o aumento na densidade de plantio. A maior produção por área foi obtida com a densidade de 20.000 plantas ha-1, no primeiro ano, e de aproximadamente 15.000 plantas ha-1 no segundo ano.Universidade Estadual de Maringá2008-04-07info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/184510.4025/actasciagron.v27i2.1845Acta Scientiarum.
