Influence of foliar biostimulants based on seaweeds, on the development and yield of rice crops in Daule, Ecuador

Abstract

The present research work was carried out in the Limonal parish of the Daule canton, province ofGuayas-Ecuador, during the dry season of 2020. The objective was to evaluate foliar biostimulants from seaweed as a complement to edaphic fertilization to improve agronomics and quality. of grain from the soca rice crop under irrigation; the field experiment was proposed under the Random Block design, four treatments and the same number of repetitions, Duncan's test at 5% was used to compare means, agronomic and productive variables were evaluated; the Kelpak-based treatment obtained the best result for panicles per m2 , grains per panicle and grain length; Similarly, in the yield variable, it reached the highest average of 7,683 kg/ha; Consequently, it is concluded that the biostimulants were able to improve the productive variables and grain quality.
