effect of fe and zn spraying on some characteristics of mungbean using chemical and organic fertilization

to study effect of fe and zn spraying on some characteristics of mungbean, an experiment was designed as factorial based on randomized complete block with three replications in urmia university, 2012. treatments were nutrition systems (organic, chemical, integrated and no nutrition) and micronutrients (fe, zinc, no foliar application and water spraying). the plant height, pod length, number of pod, number of grain in pod, and grain yield were obtained from plants treated with organic as well as chemical and integrated fertilization systems. with regards to obtain the maximum biomass (3421.8 kg/ha) and eco-friendly benefits of organic system, it is recommended as suitable fertilization treatment. the highest plant height (37.78 cm) and grain yield (800.8 kg/ha) obtained from zn spraying, while the highest biological yield (3250.80 kg/ha) from fe spraying and foliar application of micronutrients were the same, statistically. in conclusion, zn and fe spraying cause to increase the yield and yield component of mungbean.
