Abstract :

To evaluate the effect of amino acid application and micronutrient elements of iron and zinc on yield and yield components of red bean cultivar , a split-plot experiment based on randomized complete block design with three replications at the Agricultural Research Station of Islamic Azad University Roudehen branch in Damavand in 2013 was conducted. Main plots were amino acid levels including: control (non-application of amino acid), foliar application of amino acid (1 per ml), soil application of amino acids (3 kg.ha-1 by irrigation solution) and sub plot treatment was micronutrients applications including : control( non-application of micronutrients), foliar application  of iron and zinc nano particles (2 per ml), soil application of nano particles of iron and zinc (5 kg.ha-1 dissolved in water), foliar application of chelated iron and zinc (2 per mil) and soil application of chelate iron and zinc (5 kg.ha-1 dissolved in water),Treatments were applied in three stages including: eight-leaf stage, before flowering stage and pods producing of plant. Total chlorophyll, carotenoide and chlorophyll ratio, number of pod per plant, number of seed per pod, 1000-seed weight and  grain yield were majored. The results indicated that amino acids in the soil increase grain yield of bean. Also micronutrients chelated iron and spray application of iron and zinc increased pigment of photosynthesis, grain yield and yield components of bean.
