- Abstract
The symbiosis between rhizobia and alfalfa (Medicago sativa L.) contributes to the incorporation of nitrogen in agroecosystems through biological fixation, which will depend on the adequate supply of available nutrients in the soil. The objective of this work was to evaluate the effect of the inoculation with Ensifer meliloti and the fertilization with 0, 20 and 40 kg/ha of phosphorus on the nodulation and productivity of an alfalfa pasture in the center of Santa Fe province. The inoculation and the application of increasing doses of phosphorus boosted the number of nodules, nodular biomass and forage production of the plants. The technique of inoculation led to a rise in dry matter production between 23 and 58 % with the highest level of fertilizer at 120, 180 and 240 days after planting. The addition of the strain of rhizobium selected as inoculant and phosphate fertilization were a favorable strategy to increase the production of alfalfa.
