Evaluación de cinco dosificaciones de vermicompost en el cultivo de tomate “Solanum Lycopersicum” en los invernaderos del grupo TOMAC en la parroquia General Proaño

Abstract

The present research took place in the greenhouses "del Grupo Tomac" where "Solanum Lycopersicum" is produced, in the civil parish of General Proaño - Macas. For the experimental development, it was applied a completely randomized block design based on a control treatment: five treatments with five replications, composed of 25 experimental units, and different dosages of vermicompost (0.50, 1.00, 1.60, 2.00, and 4.00) kg/plant. Instead, the results were analyzed using the statistical package InfoStat. The agricultural soil presented pH values: 4.86; C. E: 1.16 ds/m; humidity: 41.5%; organic matter: 12.28%; total N: 0.61%; P: 10.3mg/Kg; K: 0.47cmol/Kg; Ca: 4.69cmol/Kg; Mg: 1.29cmol/Kg: Zn: 2.55mg/Kg; Mn: 30.46mg/Kg, presenting aggregates of Sand: 45.10%; Silt: 17.60% and Clay: 37.30%; giving a sandy clay texture (Aa), while the vermicompost presented values of pH: 6.14; C. E: 0.47 ds/m; humidity: 70%; organic matter: 8.54%; total N: 0.43%; P: 117.6mg/Kg; K: 1.8 cmol/Kg; Ca: 9.68 cmol/Kg; Mg: 1.69cmol/Kg: Zn: 3.87 mg/Kg; Mn: 21.11 mg/Kg, with a very fine granulometry texture. For the effect of the application of the dosages of vermicompost, it was determined that there was an effect on the experimental variables of the plant as stem length, stem diameter, number of flowers and fruits, and fruit diameter. The treatment that obtained the best results corresponded to T5 with a dosage of 4kg/plant with a stem length of 159.31 cm, stem diameter of 5.18 cm; the number of flowers and fruits with 9 and 15 respectively; fruit diameter of 7.76 cm, being considered the most suitable for obtaining good results in the tomato harvest.
