New perennial grains in African smallholder agriculture from a farming systems perspective. A review
Abstract, Springer Link, 2020 Perennial grain crops are gaining increased attention from researchers as one possible solution to agriculture’s many sustainability challenges. In the Sub-Saharan African context, perennial varieties of crops such as sorghum, rice, and pigeon pea have potential to... -
Perennial plants do not have to be reseeded or replanted every year, so they do not require annual plowing or herbicide applications to establish. Annual wheat on the left, and Kernza on the right. Perennial crops are robust; they protect soil from erosion and improve soil structure. They...
