Fertilizantes orgánicos: influencia de la dosis sobre indicadores morfológicos y de rendimiento en jitomate

Organic fertilizers can be an alternative to reduce the use of conventional fertilization. Theobjective was to evaluate the effect of different doses of organic fertilizers onmorphological and yield indicators in tomato. The experiment was established under acompletely randomized design, with a bifactorial arrangement, where factor A was twogenotypes of tomato (LA-113 and H-67) and factor B, seven fertilizer treatments,integrating fourteen treatments with the combination of both factors. The experiment wasconducted commercially in beds, drip irrigation and pest and disease control, at the InstitutoTecnológico del Valle de Oaxaca, Nazareno Xoxocotlán, Oaxaca. It was determined thatthe effects of fertilization treatments had a greater determination in the response of theevaluated variables than the effects of genotypes and fertilization-genotype interaction. Theresults obtained show that inorganic fertilization favors greater plant height and precocity atflowering, fruiting and fruit ripening; however, the use of organic fertilization with a doseof 1.5 kg/plant bocashi and leached bocashi favors greater fruit size, average fruit weight,number and total weight of fruits per tomato plant.
