MOREJON-RIVERA, Rogelio; DIAZ-SOLIS, Sandra H.  e  CASTILLO, Alfredo Miranda. Influence of Biobras-16^® and QuitoMax^® biostimulants on two rice genotypes. cultrop [online]. 2021, vol.42, n.4  Epub 30-Dez-2021. ISSN 1819-4087.

The study was carried out in Los Palacios municipality, with the objective of evaluating the effect of Biobras-16® and QuitoMax® biostimulants on the yield and its components of an advanced line of rice and the commercial cultivar INCA LP-5, as a strategy to increase yields under these soil and climatic conditions. The two genotypes were evaluated with biostimulants independently and the combination of both in two stages of the crop, using doses of 25 mg ha-1 of Biobras-16® and 50 mg ha-1 of QuitoMax®. A completely randomized design with a bifactorial arrangement was used, with eight treatments of three replicates each, and five quantitative traits were evaluated. The data obtained were subjected to univariate statistical analysis. Agricultural yield was higher when genotypes were treated, confirming the potential of Biobras-16® and QuitoMax® to be used as stimulators of this trait in rice cultivation. The best results were achieved with the combinations of Line 1 with QuitoMax® and the mixture of Biobras-16® plus QuitoMax® with this same genotype.
