Microdosing of Compost for Sustainable Production of Improved Sorghum in Southern Mali

The depletion of soil organic matter is one the major challenges constraining agricultural production in southern zone Mali. This study evaluated effects compost types, methods, and dose applications on productivity sustainability sorghum. Two types (farmer practice cotton stems) were applied to sorghum at two rates (microdosing 2.5 t ha−1 broadcasting 5 ha−1) 30 farmer fields 2019 2020. treatments used included CPA (cotton stem + 100 kg DAP), CP (famer control (100 control. results showed that regardless type, applying a microdose improved growth rate, plant height, grain yield, biomass yield by 15%, 18%, 47%, 27%, respectively, when compared No statistical difference was observed 2061 between microdosing ha−1. It can be inferred application makes it possible achieve 100% fertilized surface broadcasting, with nitrogen use efficiency more than 55%. resulted an economic gain 334,800 XOF ha−1, which 27% higher obtained Conversely, contribution improvement stock varied from 12–20% for per application. Therefore, availability stems Mali presents opportunity farmers implement technology double area improve productivity.
