Title

SOME IMPORTANT FACTORS LIMITING NODULATION OF ALFALFA ROOTS IN CERTAIN REGIONS OF ISFAHAN PROVINCE

Pages

  101-110

Abstract

 Success or failure in legume establishment is dependent on soil chemical, physical and biotic properties and also crop management. The objectives of this investigation were to evaluate the indigenous population and NODULATION of SINORHIZOBIUM MELILOTI and important limiting factors for NODULATION of ALFALFA roots in Isfahan, central Iran. Soil samples were taken from different fields of ALFALFA in order to determine soil physico-chemical properties and numbers of S. meliloti. The size of these populations depend on both environmental and soil factors and generally ranges from 1.5x102 to 14.7x103 cells of S. meliloti g-1 soil. A significantly higher number of S. meliloti was present in Shahreza and Daran sites. The results also showed a significantly positive effect of soil potassium "and soil phosphorus at p£0.01 and negative effect of soil bulk density at p£0.05 on the ALFALFA NODULATION score and soil rhizobia numbers. Factors such as undesirable environmental condition (temperature, water supply), SOIL PROPERTIES, improper management of ALFALFA farms, excessive cutting and grazing, and lack of suitable rhizobia in soils were among the factors limiting ALFALFA NODULATION.
