THE ASSETS OF SORGHUM IN CROP ROTATIONS...
The assets of sorghum in crop rotations... Let’s take the case of a short rotation, based mainly on winter crops such as rapeseed, wheat and winter barley (a classic rotation in France in the Center, Burgundy or Poitou Charente). In this situation, the introduction of sorghum results in longer rotations. This is because sorghum is a “real” spring crop, which is sown late (mid-May) unlike spring barley or protein pea, which are sown in February. This 3-month time lag disrupts the cycle of grasses such as ryegrass and foxtail, considering that false seedlings grow before sorghum sowing. This reduces the seed stock of the weeds involved. Another advantage of sorghum regarding weeding: the possibility of using herbicides with active ingredients that cannot be used on other rotation crops (rapeseed, wheat or barley), which helps to better manage resistance problems in weeds. Sorghum therefore reduces the IFT (treatment rate index) at the scale of the whole rotation. Sorghum fits perfectly ...
