ORGANIC POTATO PRODUCTION WITH THE APPLICATION OF BIOAGROINPUTS IN LOS PALACIOS, CUBA

Abstract

Background: The negative effects caused by chemical fertilizers on the environment have led in recent years to the use of ecological alternatives for the management of crops of economic interest, with the application of bioproducts. Objective: To evaluate the application of the EcoMic biofertilizer and the bioproducts based on Trichoderma and QuitoMax in the production of organic potatoes. Methodology: The research was carried out at Finca “El Viñedos” Los Palacios, where 1 ha of the tuber variety SPECTRA, of Dutch origin, was planted in a Red Ferralitic leached Quartzite soil and three blocks were established, in one of which potatoes were produced conventionally (control), in another it was the combination of bioproducts (QuitoMax, Trichoderma and EcoMic) and in the remaining only QuitoMax and Trichoderma was applied. For the treated blocks, applications of QuitoMax (4) and Trichoderma (8) were made after sprouting. Results: The number of tubers per plant increased by 47 and 50% in those biologically treated (QuitoMax, Trichoderma and EcoMic) and (QuitoMax and Trichoderma), respectively. A similar behavior was obtained with the block based on QuitoMax, Trichoderma and EcoMic in the size of the tubers (caliber) with 63% while the one treated with QuitoMax and Trichoderma obtained 14%; in agricultural yield it was 31 and 21%, with QuitoMax, Trichoderma and EcoMic standing out. Implications: The production of organic potatoes is possible with the application of bioproducts. Conclusions: With the combined application of the EcoMic biofertilizer and other bioproducts, it was possible to produce 19 t of organic potatoes on the “El Viñedo” Los Palacios farm.
