Produtividade de híbridos de cafeeiro Icatu x Catimor irrigados por gotejamento, em Uberlândia - MG

Abstract

Este trabalho teve o objetivo de avaliar a produtividade de híbridos de cafeeiro Icatu x Catimor irrigados por gotejamento em Uberlândia - MG, nas safras de 2003 e 2004. O delineamento experimental utilizado foi o de blocos casualizados, com 3 repetições. Os tratamentos foram constituídos pelos seguintes híbridos: H 19-5-14-16, H 26-6-5-16, H 29-1-3-8, H 29-1-7-18, H 29-1-8-5, H 29-1-8-16, H 29-1-9-11, H 29-1-14-9, H 30-2-6-11, H 30-3-14-18, H 30-2-6-16, H 30-3-14-19, H 32-3-15-19, H 32-11-17-4, H 39-1-5-4, H 39-1-11-12, H 68-7-12-6, H 83-8-11-14, H 84-3-7-19, H 86-1-7-5, H 86-1-7-11, H 138-1-9-10, H 136-1-13-15, H 136-1-14-9, H 136-1-19-16 e H 136-1-19-4. Aos trinta e aos quarenta e dois meses após o plantio foi determinada a produtividade do cafeeiro, realizando-se posteriormente a média dos dois anos. Os híbridos H 29-1-7-18, H 29-1-8-16, H 30-2-6-11, H 30-2-6-16, H 30-3-14-19, H 32-3-15-19, H 32-11-17-4, H 39-1-5-4, H 138-1-9-10, H 136-1-14-9, H 136-1-19-16, H 136-1-19-4 apresentaram as maiores produtividades médias, em dois anos de avaliação.

This work had the objective of evaluating the yield of "Icatu x Catimor" hybrids drip irrigated at Uberlandia city - MG, on 2003 and 2004 crops. The experimental design was the block-randomized, with 3 repetitions. The treatments were constituted by the following hybrids: H 19-5-14-16, H 26-6-5-16, H 29-1-3-8, H 29-1-7-18, H 29-1-8-5, H 29-1-8-16, H 29-1-9-11, H 29-1-14-9, H 30-2-6-11, H 30-3-14-18, H 30-2-6-16, H 30-3-14-19, H 32-3-15-19, H 32-11-17-4, H 39-1-5-4, H 39-1-11-12, H 68-7-12-6, H 83-8-11-14, H 84-3-7-19, H 86-1-7-5, H 86-1-7-11, H 138-1-9-10, H 136-1-13-15, H 136-1-14-9, H 136-1-19-16 and H 136-1-19-4. Thirty and forty two months after planting the coffee yield was determined, being realized after the medium of the two years. The hybrids 29-1-7-18, H 29-1-8-16, H 30-2-6-11, H 30-2-6-16, H 30-3-14-19, H 32-3-15-19, H 32-11-17-4, H 39-1-5-4, H 138-1-9-10, H 136-1-14-9, H 136-1-19-16 and H 136-1-19-4 presented the highest medium yields, in two years of evaluation.
