In recent years there was an increase in the diversification of vegetable crops, especially for cultivation in greenhouses and organic fertilizers. The tomato sets one of the most vegetables produced in the world, and its use is justified because it is a food that has great use in industrial and semi-processed products. The use of waste poultry as a source of organic matter into fertilizer, prevents it from becoming a pollutant if handled improperly. To join the inorganic formulas are in organomineral fertilizers, which increase the efficiency of mineral fertilizers, providing reduced spending on fertilizers and promoting the improvement in soil quality. The use of organomineral fertilizer is one of the strategies that provide greater crop yield and better quality. In this context, the aim of this work was to evaluate the efficiency of this granulated organomineral fertilizer enriched with monoammonium phosphate (MAP) in the processing tomato crop. When using the organomineral fertilizer compared to mineral fertilizer, there was a fresh mass increase of fruit, number of fruits per plant and yield. When analyzing the chlorophyll content the growing season proved to be the most appropriate to evaluate your changes in tomato leaves. But at conditions studied, the organomineral fertilizer presented agronomic performance similar to mineral fertilizer. In economic terms is justified the use of this fertilizer for having a lower cost than mineral fertilizers.
