This paper shows the evaluation on HYV of pulse crops in Myanmmar. This system is evaluated based on growth decomposition model. The result of the area response function showed that the price of pulses was significant factor affecting farmers' land allocation decisions. The price of pulses and fertilizer, however, not affected output by influencing the utilization of inputs and hence, crop yield. The results of the area and yield response functions are consistent with the hypothesis of the study. The contribution of technology variables on changes in area, yield, and production will estimate by applying a decomposition model. The result showed that the adoption of HYVs and the increase in nitrogen use were the predominant sources of growth in pulses production.
