Efeito de épocas de irrigação e de parcelamento de adubação sobre a produtividade do cafeeiro ‘catuaí’.

Abstract

With the present work it was aimed at to evaluate the effect of times of irrigation and splinting of fertilizer on the productivity of the coffee tree. The experiment was led along the agricultural years 2002 to 2005 and consisted of 4 blocks, with 4 portions which had received splitting of fertilizer (4, 12, 24 and 36 fertilizer applications), each portion was divided in 5 subportions which they had received times from irrigation (A irrigated one from 01/06, B irrigated from 15/07, C irrigated from 01/09 this fertigated, D irrigated from 01/06 and fertilized manually and E not irrigated). The variance analysis of the productivity data, allowed to identify that there was just effect of irrigation times on the productivity. The test of comparison of averages possible to end that the irrigation between 01/06 and 30/09 is with the fertigation use or with manual application of fertilizers it provided the best productivity averages.
