Evaluating Effect of Biofertilizer on the Performance of Mung Beans

Mung Beans are one of the valuable agricultural plants for being a great source of protein. The experiment was conducted based on randomized complete block design at the experimental field of Islamic Azad University of Varamin-Pishva, Tehran, Iran to study the effect of vermicompost and sand on some growth indexes and agronomic traits of mung bean (Vigna radiata, Parto cultivar). During the experiment, the combinations of following factors were evaluated: vermicompost at 0, 3, 6 and 9 ton per hectare and sand at 0, 10, 20 and 30% w: w. results showed that leaf area index and root surface index increased with increasing vermicompost and sand application. Moreover, the highest shoot and root dry weight were obtained when 9 ton per hectare vermicompost and 10% w: w sand was incorporated into the soil. Application of 9 ton per hectare vermicompost and 10 or 20% w: w sand caused considerable increase in seed yield, yield components, harvest index and seed protein percentage. Therefore, application of 9 ton per hectare vermicompost resulted in better performance.
