Abstract
Background and objectives
Pulses with more than 20% protein, have an important role in providing the protein needed by humans especially in countries where livestock production and agricultural products are low. These products can be used in human nutrition as a valuable and suitable dietary supplement in combination with cereals (Majnoun Hoseini, 2015). In Golestan province, due to the positive role of mung bean in rotation, it should have a special place. Farmers of Golestan province should cultivate this useful, valuable, high-yielding, early maturing, uniform in maturity and suitable conditions for mechanized harvesting after grains such as wheat due to the low water needs of this plant in summer and proper crop rotation.

Materials and methods
In order to study traits of morphologic, yield and yield components of mung bean (Vigna radiata L.) under nitrogen and megafol fertilizer, a factorial experiment was conducted based on RCBD in three replications on research farm of Gonbad Kavous University in 2017. Nitrogen fertilizer was in four levels of 0, 50, 100 1nd 150 kg.h-1 and megafol fertilizer in three levels of 0, 1 liter and two liters.ha-1. Row spacing was 50 cm and plant on row 25 cm. In this experiment plant length, height of first pod from the ground, number of branch per plant, height of first branch from the ground, number of pod per plant, number of seed per pod, number of seed per plant, 1000-seed weight, plant yield and seed yield was determined.

Results
Results showed that effect of nitrogen on plant length and height of first pod from the ground at 5% level probability and on height of first branch from the ground, number of branch per plant, number of pod per plant, number of seed per pod, number of seed per plant, 1000-seed weight, plant yield and seed yield was significant at 1% level probability. Effect of megafol fertilizer on number of seed per pod and 1000-seed weight was significant at 5% level probability and on number of pod per plant, number of seed per plant, plant yield and seed yield was significant at 1% level probability. The maximum plant length (63.63cm), height of first branch from the ground (34.14 cm), height of first pod from the ground (8.95 cm), number of branch per plant (3.98), number of pod per plant (27.62), number of seed per pod (5.31), number of seed per plant (148.4), 1000-seed weight (43.84 gr), plant yield (6.51 gr) and seed yield (820.4 kg.h-1) was belonged to application of 150 kg.h-1 nitrogen. The minimum of traits was obtained from non application of nitrogen. Application of two liters.h-1 megafol produced the maximum number of pod per plant (26.48), number of seed per plant (141.2), 1000-seed weight (43.01gr), plant yield (6.2 gr) and seed yield (755.4 kg-1).

Conclusion
In addition, consumption of nitrogen and megafol created better conditions for growth and production of mung bean and so, the maximum of studied traits was obtained from high consumption of two fertilizers. The minimum of traits was obtained from non application of nitrogen and also non application of megafol.
