Diatoms in the culture of Vanilla sp

Abstract

The research work was carried out in the municipality of Papantla del Olarte Veracruz, Mexico with the objective of evaluating two organic products, copper citrate and diatomaceous earth, which were applied in a foliar way in 3 different varieties of vanilla: Vanilla planifolia Jackson, Vanilla pompona Schiede, Vanilla insignis Ame, in a shade-mesh cultivation system made up of ridges established in fertile land and coconut fiber. 7 different variables were evaluated: plant length, number of leaves, leaf width, leaf length, internode length, chlorophyll percentage and number of new shoots. The species with the best results was pompona vanilla, obtaining statistically significant differences in most of the variables, highlighting plant length, obtaining a difference of one meter above the other species. The results were favorable for all species, we obtained vigorous and healthy plants, since the products not only acted as fertilizers but also as insecticides and fungicides, nourishing them, avoiding fungal infection and the presence of different harmful insects for the plant. Demonstrating to producers that it can be grown while being friendly to the environment and obtaining favorable results.
