Conteúdo: 	High soil temperatures and low soil moisture stresses for 7 days  after planting were utilized to evaluate inoculant types and rates on soybeans grown in a rhizobium japonicum-free soil in Puerto Rico. All inoculant treatments were evaluated under stress conditions in the half ofthe experiment that did not recieve rain or irrigation and that had a moisture level below the wilting point for the first 7 days. During this period in the dry section, the soil temperature at 2.5cm reached a maximum of 38o to 40oC. All inoculant treatments were also evaluated in the half of the experiment that was irrigated to provide a moisture level near optimum. This moisture reduced the maximum soil temperaturesat 2.5cm to between 31 and centigrade. The granular soil inoculant was the best treatment in prodicing tap root nodules, total number of nodules, and nodule dry weight per plant after both 32 and 98 days. Liquidsoil inoculant in the seed furrow and liquid placed 2.5cm below the seed were generally better than all remaining treatments, i.e., liquid  5.0cm below the seed, liquid 7.5cm below the seed, and peat powder inoculant applied to the seed. Applying all inoculants at 10 times the normal rate produced a consistent but not significant increase in nodulation parameters when each inoculant treatment was compared to its standard rate, except for the granular soil inoculant were significant nodulation increases were observed in 8 of the 12 evaluations. Nodulationunder dry and irrigated conditions was compared by totaling the
