The research aims to study the peas cultivation growth in Thamar and Yemen and influencing factors by estimation of secular trend equations for area (ha), production (ton), productivity (ton/ha) during 1990-2013, It also aims at estimation function of peas production by using Cobb-Douglas function and analysis cost and returns of peas crop depeding on the primary data that was collected from random sample of farmers (37 farmers) in Al-Qa’mah and Manqathah villages in Thamar governorate for the summer season of 2014. The results showed that area and production of peas regressed in Thamar and Yemen but productivity of peas grew at a little increasing rate during 1990-2013, also results showed that, Cobb-Douglas function was significant at 5% level with R2 76%. Seeds quantity factor was significant and positive related to production of sampled farmers, while the remaining factors (pea area, number of irrigation times and labor) were non-significant but positive related to production. Average productivity of peas was estimated at 1.342 ton/ha and proportion of return/cost ratio was estimated at 1.74.
