ii) Name the crops which are mostly rotated with wheat.
Answers
. By alternating grain crops, like wheat, with broadleaf crops such as canola, lupin or a pasture crop like medics
By including legume crops like lupin, vetch, peas and legume pastures you have the ability to fix nitrogen
By including a legume crop the average yield increases even more. In the lw sequence wheat is planted following lupin and in the mw sequence, following medic pasture. The average yield of the wheat following lupin was 781 kg/ha more than in the monoculture and 944 kg/ha more following the medic pasture. The extra nitrogen in the system that was fixed by the legume crops and weed control contributed to this increase. By alternating a grass crop with a legume or a broadleaf crop like canola, you can control grass weed in those years lessening the competition with a grass cash
