Description
Summary:Organic fertilization is a cheaper and highly effective option for profitability and consequent improvement of the soil's physical, chemical, and biological structure. Thus, the objective of this work was to evaluate different types of fertilization: organic (poultry shed litter), mineral, and leaf path on yield parameters of lettuce grown in various types of planting. The treatments consisted of using two planting systems (P1 - Line and P2 - quincunxes) and mineral and organic fertilizers (A1 - mineral fertilization; A2 - mineral fertilization + leaf fertilization; A3 - organic fertilization with poultry shed litter and A4 - fertilization organic + mineral). The experimental units consisted of 36 and 52 plants, respectively, for treatments P1 and P2, and all central plants of the experimental unit were evaluated. Heart height, fresh mass, and leaf number were observed. The mineral and mineral + leaf treatments did not differentiate, either in line or in quincunxes. The treatment that stood out about the analyzed variables was the organic fertilization and quincunxes planting system, reflecting a more significant number of lettuce plants and better use of the area.
