Profitability of Tamarindus Indica and its Suitability for Agroforestry Tree for Sustainable Household Incomes in Kano State, North-West Nigeria

Abstract

The study investigated the profitability of tamarind processing and marketing and its suitability for agroforestry tree for households; incomes in Kano State in North-Western Nigeria. Specifically, it examined the socio-economic characteristics of processors and marketers, determined cost structure, revenue, profitability, assessed market structure, estimated profit efficiency, and identified constraints limiting the subsector. A multi-stage sampling technique was used to select 171 processors and marketers. Descriptive statistics, gross margin, Herfindahl-Hirschman Index (HHI) and stochastic profit frontier were used as analytic techniques. Results indicated that Tamarind processing was male-dominated (72.93%), while marketing was largely female-driven (57.89%). Older processors (mean = 45.25 years) than marketers (38.68 years) were observed. Most were married (88.72% and 76.32%, respectively). Educational levels varied, with many processors having Quranic or secondary education (29.32% each), while marketers were better educated (55.26% secondary, 34.21% tertiary). More of the Processors were married than the Marketers. Average household size was larger among processors (11.28) than marketers (6.18) were. Business experience was higher among processors (17.38 years) compared to marketers (9.00 years). Profitability analysis showed that in Kano, raw materials accounted for 52.83% of total variable costs (TVC), followed by transportation (22.85%). With a TVC of ₦1,235,960.76 and revenue of ₦2,436,789.00, gross margin stood at ₦1,200,828.24, indicating high profitability. Kano processors had mean efficiency of 0.8794, indicating operations at 88% of maximum profit, while marketers had lower efficiency (0.6098). Efficiency was enhanced by education and household size, but reduced by rent, age, and business experience. Key constraints included inadequate capital, price fluctuations, and lack of storage facilities, with high transport costs and poor road networks significant in Kano. Overall, tamarind processing and marketing are profitable ventures in the study areas, though with varying efficiency and profitability margins. Education levels of the household size were the variables observed to increase efficiency of the processors, while source of tamarind and business experience were the variables increasing the efficiency of the marketers.
