ORGANO-MINERAL FERTILIZER APPLICATION: AN ALTERNATIVE FOR PRODUCTION OF CORN (Zea mays L.), IN SIALYTIC BROWN CARBONATED SOIL.
ABSTRACT. For three years, an experiment was conducted in areas of the Research Institute (INIVIT ) Camaguey , using different organo- mineral fertilizers , in order to study its influence on the performance of maize ( Zea mays , L ) on a Fluffy Sialytic Brown Carbonated soil slightly acidic pH , low P2O5 and K2O and medium organic matter. For organo- mineral mixtures were used as organic fertilizers and cow manure and cachaza and mineral fertilizer, triple superphosphate and potassium chloride. The organo- mineral was applied at the time of planting at a dose of 745 kg ha1 according to each treatment, which were replicated 4 times in a randomized block design . Yield and its components were measured and soil samples were taken to determine the variation of their properties. Data were evaluated by analysis of variance from dual and multiple range test of Duncan applied for a significance level of 5%. The results show that the use of the organo- mineral fertilizers increases performance, reduces chemical fertilizers to be used and improve the properties of the soil.
