Abstract :
To investigate the effect of foliar application of micronutrients on chlorophyll and protein content and yield of alfalafa populations and evaluate economics obtain cost- effect, an experiment was carried out in split split plot by time with four replications using a randomized complete blocks desighn at the Shahid Zendeh-Ruh Agricultural Research Center of Kerman. Experimental treatments were micronutrients with five levels: Fe, Zn, Mn, Fe+Zn+Mn and control (without nutrient applications), bacterial inoculation, with three levels: Rhizobium melilloti, Rhizobium legumenasarum and without inoculation. Foliar application had a positive significant effect on all traits under study and increased chlorophyll and protein contents, and alfalfa forage yeild. The highest fresh forage yield belonged to second cutting (71 t.ha-1) by using combined micronutrient foliar application and to third cutting (68 t.ha-1) by using Rhizobium leguminosarum. The highest protein rate was observed in Mn foliar application and Rhizobium meliloti inoculation at second cutting by 50%. Based on the results obtained it can be concluded that foliar application of micronutrients and inoculation with Rhizobium bacteria improves morphological characteristics of Bami population of alfalfa in Kerman region.
