This study investigates the impact of spacing and fertilizer application on tigernut yield and nutrient content. The research findings reveal that spacing and fertilizer application significantly influence various yield attributes, including herbage weight, nut weight, and herbage yield. Furthermore, nutrient concentrations (N, P, K, Fe) in tigernuts vary significantly across different treatments, providing valuable insights into their nutritional content. Proximate composition analysis highlights differences in ether extract, ash content, protein content, moisture content, fiber content, carbohydrates, and dry matter. Additionally, nutrient uptake in tigernuts is influenced by spacing and fertilizer application. As a result, recommendations are made for optimizing crop management practices, tailoring nutrient management, exploring potential applications based on proximate composition, and encouraging further research in tigernut cultivation. These findings contribute to enhancing tigernut cultivation practices and broadening its potential applications in various industries.
