Effect of the irrigation time and fertigation on the productivity and physical quality of coffee (1999/2000 crop)
A field experiment was conducted on a 14-year-old coffee plantation in Lavras, Minas Gerais, Brazil, during 1999/2000 to investigate the effect of different fertilizer splittings and irrigation scheduling on coffee yield and grain classification forsieving. The fertilizer treatments were: 36, 24, and 12 fertilizer applications through fertigation and 12 fertilizer applications by hand. The different irrigation scheduling were: 1 June-30 September (A); 15 July-30 September (B); and 1-30 September. The subplots without irrigation were fertilized through four applications by hand (D, with the same fertilizer applied on the treatments submitted to fertigation, and E, with the fertilizer normally used on hand applications). The highest crop yield (6300 kg/ha) was obtained on the treatment irrigated during 1 June. Irrigation scheduling significantly affects the grain classification for sieving. For most of the treatments, coffee grains were classified as medium plain grain.
