Risk: we all know what that means, right? But why is it such a critical part of our HarvestChoice portfolio, what does it mean when you look through the lens of farming in Sub-Saharan Africa?
Long-term yield trials are great resources for agricultural researches in multiple disciplines, but such dataset have not been readily available in Sub-Saharan Africa. The Hatfield Experimental Farm in Pretoria, South Africa, is an exceptional case that has been providing maize yield and fertilizer trial dataset with 32 treatments since 1939. In collaboration with University of Pretoria, HarvestChoice facilitated the re-discovery of raw yield dataset from the trial to study the measured long-term yield variability.
Water availability is the most critical factor for sustaining crop productivity in rainfed agriculture. Even if a drought-tolerant trait is introduced, water isn't available to crops when there is no water in the soil. Rainfall variability from season to season greatly affects soil water availability to crops, and thus pose crop production risks.
