Nodule number and specific nodulation ability when treated with Carbodan 35 ST at the dose of 3 L 100 kg-1 seeds exceeded that of the control by 23% and 7%, respectively. It was found that the insecticides tested did not depress the nodulation. The insecticides Promet 400 SK (furathiocarb) at the dose of 3 L, and Carbodan 35 ST (carbofuran) at the dose of 1, 2 and 3 L 100 kg-1 seeds were used.
