Tomato yield and quality under various combinations of organic compost
The number of growers and planted area dedicated to organic farming have increased considerably. Consequently, demand has increased for alternative organic composts in terms of quantity and new options for direct use with crops. Making use of local industrial byproducts is also important throughout Brazil and the rest of the world. Therefore, it was evaluated the effect of eight types of organic composts, produced with different percentages of poultry litter and crushed sugarcane on tomato yield and quality. The experiment was carried out during the 2013 growing season at the experimental farm of the Agricultural Research Company of Minas Gerais state (Empresa de Pesquisa Agropecuária do Estado de Minas Gerais) located in Prudente de Morais, MG, Brazil. It was evaluated different formulations of poultry litter and crushed sugarcane (0, 10, 20, 30, 40, 50, 50, 60 and 70%) yielding eight types of alternative Bokashi used as organic compost in the production of two tomato cultivars (Santa Clara and the Verano hybrid). It was found that the various formulations of alternative Bokashi, except the alternative Bokashi B1, strengthened components of tomato yield and quality. We found that composts of poultry litter and crushed sugarcane increase tomato yield and quality and can be and excellent alternative, especially for organic farmers.
