The need to reduce the use of pesticides in agriculture, together with the importance of maintaining optimal production, encourages the search for fertilization options according to these demands. The objective of this work was to evaluate the response of rice cultivation to the foliar application of organic fertilizers made. Three levels of application were used, such as: Biol diluted at 10%, 25% and 40%. Manure tea diluted to 10%, 25% and 40%. Humic acid diluted to 10%, 25% and 40%. An absolute witness and a chemical witness. Fertilizing the biol at 25% when determining the response of the crop to the foliar application of fertilizers, was the one that showed the best results with respect to the number of counted panicles. The application of humic acids at 40% is the best fertilizer and dose in terms of number of tillers, but like the number of panicles, it did not significantly affect yields. All organic nutrition treatments were statistically similar in rice grain yield, higher than the absolute control, but lower than the chemical control, the latter not considered as a clean product.
