Abstract

The number of functional leaves in the commercial production of bananas (Musa spp.) is directly related to the bunch weight and size. The emission of leaves is negatively affected by adverse environmental conditions, and the emission rate may vary. The Spanish company Catalysis S.L. is in charge of producing and then commercializing the bioproduct VIUSID® agro, and it develops an excellent promotional work for the development of research in many countries. This research was carried out at the Research Institute of Tropical Roots and Tuber Crops (INIVIT), located in the municipality of Santo Domingo, province of Villa Clara to determine the effect of VIUSID® agro doses on the Foliar Emission Rate (FER) in bananas, during the period July-September 2021. Nine applications every seven days, two months before flowering at the dose of 0.50L/ha/application, offered a significant influence on the variable, whose value doubles in relation to the control treatment, this aspect is essential for the quantitative analysis of the growth of banana Musa AAA cultivar, Cavendish subgroup, ‘ Cavendish gigante’ cultivar. The treated plants reached flowering with a greater number of formed leaves. The number of emitted leaves per each plant every seven days can be modified by the man´s work by using VIUSID® agro.
