Evaluación de dos bioestimulantes en el desarrollo vegetativo de tomate riñón (Lycopersicon esculentum) en la parroquia Eloy Alfaro, cantón Latacunga

Abstract

Nowadays the tomatoes (Lycopersicon esculentum) are vegetables with highly valued all over the world, because the fruit has a lot of nutrients and vitamins. This crop is very important in our country, that is why it is essential to get a good production and profitability, with this research we’re obtained plants with good growing, resistant to stress situations and pathogens attack. Therefore, with this background, it was evaluated two biostimulants those were Isabion and Elixir, which were used in three doses 1,5; 1,0 and 0,5 cc/L in the vegetive development of tomato (Lycopersicon esculentum). It was used a net parcel of each experimental unit was consisted by ten plants with an area of 0,18 m2 , with three repetitions with an experimental design of random blocks in factorial arrangement of 2x3+1. The variable evaluated were root volume, root length, number of leaves, plant height, stem diameter, days of appearance of the inflorescence; the data logging was made forty days after the transplant, the comparation was made with Tukey Tests at 5% on Infostat program. At the end of the analysis, it was determined that the proper dose for Elixir was 1,0 cc/L (D2) when generating the best results in the variables of root length and plant height, while for Isabion the dose was 1,5 cc/L (D3) in root volume and stem diameter. However, neither of the two products influenced in the number of leaves and days of appearance of the inflorescence, considering that this depends on many factors such as environmental conditions, genetic characteristics of the variety, therefore, so it manifested that the use of biostimulants helped positively in in the vigor and vegetativedevelopment of tomato.
