Vegetable production in Nigeria: the growth and limiting factors

Vegetable cultivation is a significant component of Nigeria's agricultural sector and has gained increasing attention due to its economic and nutritional advantages. Vegetable production provided Nigerians with a viable option to obtain nourishing food, thereby addressing the issue of food insecurity. The production has proven to be a lucrative source of revenue for numerous individuals, particularly those engaged in small-scale farming. To examine the growth, a secondary data on the trend in the harvested area and production/yield of selected vegetables (Tomatoes, Okra, Potatoes, Onions Shallots and Chillies Pepper) in Nigeria was collected and discussed. The primary limiting factors in the sector were also discussed, with the goal of finding solutions to overcome these problems and fully exploit the potential of vegetable production to ensure food security. A comprehensive dataset spanning 30 years (1992-2022) from a reputable source (FAOSTAT) was gathered, which included time series data on vegetables. For the 30 years analyzed, Tomatoes experienced increment in the area harvested and yield by 94.3% and 89.1% respectively over the years. The area harvested and yield of Okra also increased to 87.6% and 71.2% respectively over the years. The area harvested and yield of Potatoes increased by 96.8% and 39.4% respectively. Onions and Shallot’ area harvested and production over the years also increased by 52% and 38.4% respectively. An increment by 32.5% and 22.2% for the area harvested and yield respectively was also recorded for Chillies and Pepper over the years. The data indicates that the vegetables examined had annual growth rates that generally increased; however, there were occasional years with no change and while some years recorded a decline. The vegetable production sector of agriculture in Nigeria is currently growing, although it is still not reaching its maximum potential.
