Abstract— Tested using a modified split plot design in randomized complete block with the main treatments bean varieties and sub-levels of nitrogen fertilizer treatments were performed. The results show that the variance in total dry matter accumulation of bean varieties Treatment plant and the different levels of nitrogen fertilizer has been so significant at 1% of the total plant dry matter accumulation increased with increasing nitrogen. This is due to increase in line with the increased photosynthesis and leaf area index and dry matter accumulation in plants. Sigmoid curve diagram of a bean leaf area index figures showed that growth in primary school, which had up to 50 days after the Kennedy Planting of the LAI value is only 0.7 is taken to slow the spread of leaf area index for the legume family, the high levels of nitrogen fertilizer (80 kg/ ha) the first period to reduce the level of leaves, and secondly in the treatment of lower levels of nitrogen treatments were applied to the leaf area index was higher. Chart for RGR at different levels of nitrogen reduction process and that their maximum RGR in the early stages of development with 0.15 g per day is reached. NAR average value equal to 6.7 grams per square meter per day is 48 days after planting in the NAR to the 7.4 grams per square meter per day increased and then showed its decreasing trend.
