Evaluación de cuatro bioestimulantes en la inducción de la resistencia sistémica en pepino ( Cucumis sativus L.) y tomate ( Solanum lycopersicum Mill.) en monocultivo y cultivo asociado en invernadero

Abstract In order to evaluate four biostimulants in the induction of systemic resistance in cucumber (Cucumis sativus L.) and tomato (Solanum lycopersicum Mill.) in monoculture and associated greenhouse cultivation, five treatments were applied at three developmental stages (growth, flowering and fruiting): T1 Bioremedy (2.0 g/L), T2 Grandsil (2.0 g/L), T3 Control (water), T4 Fossil (5.0 g/L), T5 L-amino (2 cm3/L). The treatments were distributed in a 3 x 5 factorial arrangement and evaluated in a completely randomised experimental design. Each experimental unit consisted of three rows. The response variables were: plant height (cm), stem diameter (mm), number of fruits per plant, fruit volume (cm3) and fruit weight (kg). The results, cucumber in monoculture did not present notable differences for any of the evaluated variables, with the exception of plant height, significant differences were observed at P
