干旱区生态环境知识资源中心

In this study was performed in the Research Station, Islamic Azad University of Ahvaz fact Southern city of Ahvaz in the geographic profile: latitude: ’20 degrees 31 Longitude: ’40 degrees 48 Altitude: 18 m and average rainfall: 256 mm. Experiment where climate is arid and semi arid and according to weather data Ahvaz 40 213.94 mm average annual precipitation, average annual temperature of 25.24, 32.94 Average annual maximum temperature, mean minimum degree Annual Heat 18.4 degrees C is. Minimum temperatures in agricultural experiment 4.2 in January and maximum temperatures in September 52 have been reported. Some results of various investigations have shown that the number of branches with a yield direct positive correlation shows that, as the number of branches in the optimal density keeps the number of pods per unit area results in much desirable, is placed and yield increases examining this relationship in correlation bean plant (0.72 = r) was calculated and a direct positive relationship (but not too high) showed the cause of this is desirable density that can be used in seeding experiments were created with the low number of branches and their small share of production as the main stem pods to be. Applying 100 kg ha, correlation higher than the other two treatments, 50, 20 kg ha of nitrogen fertilizer showed (0.76 = r) and this is production of branches in high levels of nitrogen fertilizer. Split application of fertilizer in different periods together and showed no correlation in terms of average correlation coefficient of them (0.74= r), respectively. With the number of branches per plant FabaL correlation coefficient (0.69 = r) was calculated and a direct positive regression (but not too high) of it’s offered. Applying more fertilizer in tests to increase the number of branches found significant spatial yield was increased. Among the figures of the number of digits Blessing had more branches that this figure will increase performance. [Tayeb Saki Nejad. Forming branches in the bean and its relation to yield.
