It was studied the possible allelopathic effect of Brachiaria decumbens on initial development of Citrus limonia in greenhouse. The dry matter was incorporated into the soil in 0, 1,5, 3,0% (w/w)-proportion. Biometric parameters and physic propert ies of soil were determined by soil solutio n. Greatest propotion reduced all the biometric parameters analyse d. Physical properties of nutrient levels (except N) of soil did not observed significantly alterations. Greatest proportion reduced the average stem diameter of Citrus limonia at 57%. Probably, these results were due to lack in nitrogen level observed in soil solution.
