Abstract

Lettuce is very important in human nutrition standing out as a source of vitamins and minerals. Several authors report the application of organic fertilizers providing increases in productivity and quality of this crop. The objective of the study was to evaluate the cropping system of lettuce fertilized with organic matter avian bed base, under the conditions of the municipality of Urutaí - GO. The experimental design was a randomized block in factorial 3x5, totaling 15 treatments, corresponding to three lettuce cultivars (curly, head and purple) submitted to five levels of organic matter avian bed base (0, 30, 60, 90 and 120 m3 h-1). The results were submitted to analysis of variance, where the description of variables was performed according to the levels of organic matter avian bed base, performing the polynomial regression. For the study conditions of application it is recommended that approximately 85 m3 ha-1 of organic matter avian bed base, the cultivation of cultivars curly and head.
