Paul Douglas and Charles Cobb developed this production function in the 1920s. Since then, it is widely used because it simply captures key aspects of production processes. Pre-defined farm types, which are … Read more
1. Introduction Cocoa production is integral to Nigeria’s agricultural economy, particularly in the Southwest region, which accounts for a significant share of the nation’s output. This region benefits from favorable agroecological conditions, such as loamy soils, tropical climate, and a structured farming economy, which collectively make it conducive to high-quality cocoa cultivation [23][15].

Introduction Phytohormones Plant hormones, also known as phytohormones, are chemical substances produced spontaneously in plants that regulate physiological reactions at low concentrations. Phytohormones are classified into two groups: growth promoters and growth inhibitors. Growth promoters enhance cell division, expansion, pattern creation, tropic growth, flowering, fruiting, and seed formation. Growth inhibitors involve numerous growth-inhibiting activities such … Read more
