Foliar application of amino acids improves growth and productivity of radish (Raphanus sativus L.).

Resumen

Objective: Foliar application of amino acids can be an ecological alternative to increase the productivity of horticultural plants. Therefore, the objective of this study was to evaluate the effect of foliar application of the amino acid-based growth promoter VIUSID agro^® (VA) on the radish growth and productivity variety 'Red Hazera'

Design/methodology/approach: An experiment was carried out in a randomized block design with three treatments and five replicates. A control (VA0) and two concentrations of the growth promoter at 1.2- and 1.5-mL L^-1 were applied in improving leaf area, chlorophyll content, dry and fresh biomass of leaves and tubers, growth rates, and agricultural yield.

Results: The results showed that the foliar application of growth promoter influenced positively on radish growth and productivity, especially the concentrations of 1.5 mL L^-1 showed higher TCC, TAN, FTB, polar diameter and increased agricultural yield by 21% compared to the control treatments Nonetheless, foliar application of growth promoter at concentration of 1.2 mL L^-1 improves TDB, CC, LFB, LA and the agricultural yield was 10% high than the control treatment.

Limitations on study/implications:

Findings/conclusions: Taken together, the results of this study indicated that foliar application of growth promoter is an alternative strategy for increasing radish productivity under garden conditions.
