Abstract

In order to investigate the effect of LIGHT intensity on growth and biological NITROGEN FIXATION (BNF) in subclover (Trifolium Subterraneum.L) an experiment was conducted using a completely randomized design with 4 replications and LIGHT intensities of 184,480,791 and 1912 mol. m. s. The experiment carried out in growth chamber using a sand medium and a nutrient solution (without nitrogen). Seedling grown was harvested after 55 days. At this time, the number and fresh weight of nodules, dry weight of root, shoot and total leaf area, and nitrogen percentage in root and shoot were measured and analyzed statistically. The results showed that nodule number and fresh weight, leaf area, root, shoot and total dry weight, root and shoot nitrogen percentage are increased with increase in LIGHT intensity. Increasing LIGHT intensity was more effective on shoot dry weight compared to root dry weight: Increasing LIGHT intensith increased root nitrogen percentage by 2.1.
