Fruit production and classification of four cherry tomato genotypes under an organic cropping system Producción y clasificación de frutas de cuatro genotipos de tomate cereza en sistema orgánico João Batista de Campos Menezes 1* , Cândido Alves da Costa 1 , Regynaldo Arruda Sampaio 1 , Hugo César Rodrigues Moreira Catão 2 , Denilson de Oliveira Guilherme 3 , Roberto Antonio Savelli Martinez 2 ABSTRACT A field experiment was carried out in the Instituto de Ciências Agrárias of Universidade Federal de Minas Gerais, Montes Claros, MG, Brazil, during the summer of 2008-2009, to evaluate the productive features of cherry tomato genotypes cultivated under different spacing, in an organic cropping system. The experimental design was randomized blocks in a 3x4 factorial scheme with three replications. The experimental plot was made up of four rows (spaced 1.00 m between rows) with thirty two plants each, utili- zing the eight central plants for the analysis. The treatments consisted of three genotypes of cherry tomatoes (CH152, CLN1561-A and Carolina) and four spacings between plants (0.40; 0.60; 0.80; 1.00 m). The fruit percentage in the different diameter classes and the commercial fruits yield per plant and hectare were evaluated. The CH152 genotype produced a greater percentage of non- commercial fruit (with diameter less than 20 mm). The greatest percentage of fruit classified with the largest diameters (above 30 mm) was achieved by the CLN1561A genotype. The highest commercial yields of fruit per plant and per area were found in the CLN1561A genotype, pointing it out as a promising genotype for an organic crop in the summer in the north of Minas Gerais. Key words: Solanum lycopersicum L., alternative farming, plant density, productivity. RESUMEN Un experimento fue conducido en campo, en el Instituto de Ciencias Agrarias de la UFMG, Montes Claros, MG, Brasil, durante el verano de 2008 y 2009, para evaluar las características productivas de genotipos de tomate cereza cultivado bajo diferentes espaciamientos, en sistema orgánico. El delineamiento experimental fue el de bloques casualizados, en esquema factorial 3 x 4, con tres repeticiones. La parcela experimental fue compuesta por cuatro líneas (espaciadas por 1,00 m entre líneas) con 32 plantas cada una, adoptando como área útil las ocho plantas centrales. Los tratamientos consistieron de tres genotipos de tomate cereza (CH152, CLN1561A y Carolina) y cuatro espaciamientos entre las plantas (0,40; 0,60; 0,80; 1,00). Se evaluó el porcentaje de frutas en las diferentes clases de diámetro y los rendimientos de frutas comerciales por planta por hectárea. El genotipo CH152 produjo mayor proporción de frutas no comerciales (diámetro menor que 20 mm). La mayor proporción de frutas clasificadas con diámetros mayores que 30 mm fue alcanzada por el genotipo CLN1561A. Los mejores resultados de productividad comercial de frutas por planta y por área fueron observados en el genotipo CLN1561A. Palabras clave: Solanum lycopersicum L., agricultura alternativa, densidad de siembra, productividad. Introduction The tomato is a vegetable consumed mainly in natura that is currently causing consumer concern, especially because of the possibility of contamination with chemical pesticide residues. This concern has generated a significant increase on the demand for products free of pesticides and certified by agencies such as IBD (Biodynamic Institute) (Luz et al., 2007). The tomato crop is highly susceptible to pests and diseases, and is currently the second vegetable
