Evaluation of three bioproducts applied to seeds on the yield of tomato (Solanum lycopersicum L.) var. Amelia

Abstract

The objective of the study was to evaluate the effect of the bioproducts Ecomic® (Mycorrhizae), Azofert F® (Rhizobia) and QuitoMax® (chitosan) on tomato yield when applied to seeds prior to sowing. Treated seeds were sown in a traditional seedbed under a completely randomized design. Plants were planted at 0.90 m and 0.30 m apart. During the reproductive stage of the crop, the variables number of flowers and number of fruits were counted. At the third harvest, polar diameter, equatorial diameter, fruit mass and yield were evaluated. The bioproducts applied produced variations in the variables evaluated, obtaining the best results when the seeds were embedded with QuitoMax®, Azofert® and Ecomic®, with a yield of 35 t ha -1 , 30 t ha -1 , 28 t ha -1 , respectively, and 25 t ha -1 in the control treatment.
