**Abstract**

Vegetables are important for maintenance of good health; their production and marketing are veritable sources of employment and livelihood. To promote vegetables' contribution to the above, there is a need for sustainable and efficient production process. The paper reviewed production, socioeconomic factors, and constraint affecting efficiency of production of three important vegetables (tomato, pepper, and onion). The review showed that socioeconomic factors found to increase technical efficiency in vegetable production were educational level, extension contact, and household size. Influence of farmer age on technical efficiency was inconclusive due to varied opinions. Increase in farm size, quantity of seed, amount of fertilizer, and agrochemical were found to have positive influence on output. Majority of the literature reviewed opined that increase in quantity of labour raises productivity; however, it must be utilized efficiently. The mean technical efficiency of the vegetables varied from the southern to the northern part of the country. The cross cutting constraints in vegetables production are pest and diseases, inadequate storage facilities, and high cost of improved inputs. The study recommends increase awareness and sensitization on optimum levels of resource use for increased productivity and appropriate intervention to constraints in the value chain.
