In: HortscienceSummary: Se ivestigo el efecto de la compactacion del suelo en la nodulacion, eficiencia nodular y crecimiento de la soya y del frijol blanco en un ambiente controlado. Existe una relacion inversa entre la compactacion del suelo y la biomasa radical, el crecimiento de brotes y el area foliar total de la planta. El PF y el no. de nodulos/planta, la actividad de nitrogenasa y el contenido de leghemoglobina/unidad de peso nodular disminuyeron en la soya y en el frijol blanco a medida que la densidad volumetrica del suelo aumento de 1.2 a 1.6 g/centimetro cubico. (RA-CIAT)Summary: The effect of soil compaction on nodulation, nodule efficiency, and growth of soybeans and white beans was investigated in a controlled environment. There was an inverse relationship between soil compaction and root biomass, shoot growth, and total leaf area of plant. FW and no. of nodules/plant, nitrogenase activity, and leghemoglobin content/unit wt. of nodule decreased in both soybeans and white beans as bulk density of soil increased from 1.2 to 1.6 g/cubic centimeter.
