Growth and Development of Cucumber Plants (Cucumis sativus L.) Biostimulated with QuitoMax® ; Crecimiento y Desarrollo de Plantas de Pepino (Cucumis sativus L.) Bioestimuladas con QuitoMax®

Chitosan as a natural biostimulant promotes the growth and development of crops, development and yield of crops. Several studies have proven the efficacy of chitosan to improve cucumber production, the study of the response to different doses of chitosan is necessary, therefore the objective of the present study was determine the effect of six concentrations of chitosan on the growth and production of the cucumber crop. Six treatments: T1= Control; T2= QuitoMax® 100 mg L-1; T3= QuitoMax® 200 mg L-1; T4= QuitoMax® 300 mg L-1; T5= 400 mg L-1 and T6=500mgL-1, were applied by manual spraying at 15, 30 and 45 days after transplanting the hybrid cucumber ?Diamante ?F1, ?using ?a ?randomized ?block ?experimental ?design ?with three repetitions and five plants per experimental unit. The variables length of the guide, number of fruits per plant, length, diameter and weight of the fruit, and yield in kgha-1 were recorded. The length of the guide was measured at 15, 30 and 45 days, so for this variable a model of repeated measurements in time and comparison of means by least squares, for the rest of the variables an orthogonal polynomial analysis was used to determine the response of the variables to the different concentrations of chitosan. All variables presented a positive linear response to the application of chitosan. It is concluded that chitosan influences the growth and development of the cucumber plant. Increasing its yield as the dose of chitosan increases. The dose of 500 mg L-1 in this study was the one that had the best results. The need to study higher doses of chitosan is suggested. ; El quitosano como bioestimulante natural, promueve el crecimiento, desarrollo y rendimiento de los cultivos.
