GROWTH AND PRODUCTIVITY OF TOMATO UNDER USE OF BIOSTIMULANT AND AGES OF SEEDLING TRANSPLANTATION
Abstract
The age of the seedlings in the transplant, as well as the use of biostimulants in their production, are factors that can influence the good quality of the seedlings, which is fundamental for the good development of the plant, and can affect the final production in the tomato crop. Considering that age and the biostimulant are factors of great interest to producers, that there are ambiguities in the results of previous scientific research and that the answers may be inherent to the genotype, the objective of this study was to evaluate the effect of the age of tomato seedlings, hybrid H9553, in the transplant, treated or not with the Stimulate® biostimulant, in the development of the plant and in the production of fruits. Pre-transplant evaluations were performed at 20, 30, 40, 50, 60 and 70 days after sowing and post-transplant evaluation at 78 days after transplant. The experiment was carried out in a randomized block design, with four replications. Ten plants were used, per plot, for evaluation. The factorial scheme 2 x 6 was carried out, where 6 correspond to the age of the seedlings and 2 correspond to the use or not of Stimulate®, in the transplant. After the subjection of the statistical data, it was concluded that the growth of the plants, from 20 to 70 days after sowing, has a linear or quadratic tendency. The age of transplanted seedlings, from 20 to 70 days after sowing, does not interfere with fruit production. The use of Stimulate®, alone or in interaction with the age of the seedlings, does not influence plant growth or fruit production.
