Soybean is a plant of the genus Glycine, its grain has had its consumption expanded in the last three decades. The objective of this work was to determine the vegetative growth of soybean under the influence of different irrigation water temperatures in the soil. The experiment was carried out in the greenhouse of the Nursery sector of the Federal University of Mato Grosso – Sinop Campus, from April 8, 2022 to July 22, 2022. The experimental design was in randomized blocks, with five replications (in pots) studying irrigation water temperatures are: 10Cº, 20Cº, 30Cº, 40Cº, 40Cº, 50Cº and 60Cº. 5 replicates were used. Plant height (AP), leaf area (AF), root dry mass (MSR), shoot dry mass (MSPA) were evaluated. The water applied by irrigation in the cultivar ANsc 89 109 must be in the temperature range between 10 and 30ºC. The application of water with a temperature of 40ºC above impairs the vegetative growth of the soybean crop, which will lead to a reduction in the final grain yield.
