Co-design of locally adapted wheat variety mixtures (Liveseed Practice abstract)

Abstract

Practical recommendations ● limit disease development by keeping proportion of susceptible varieties < 30%, and by using varieties able to compensate through high tillering ability or high TKW (thousand kernel weight). ● increase weed control through wheat competitive ability by (i) using varieties with early vigour or high tillering ability, (ii) diversifying varieties for earliness, height and growth habit. ● face nitrogen stress by (i) tolerating an early deficit, by complementarity (ii) in time of nitrogen demand (diversified earliness), or (iii) for nitrogen use efficiency
