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.
