Observe the gross margins of each crop (\u00a0display)\u00a0:\u00a0command). It can be noted that the crop with the highest gross margin is potato. The land area dedicated to potato is limited by the rotation constraint, and the model represent a 1\/6 of the total land area dedicated to potato crops. The second crop in terms of gross margin is durum wheat ; the model produces durum wheat until it reaches the rotation constraint limit (2 years out of 3). Every year the farmer divides his land area as follows : 4\/6 for durum wheat, 1\/6 for potato and 1\/6 for rapeseed.<\/p>\n<p>Rotation is therefore as follows : durum wheat, durum wheat, rapeseed, durum wheat, durum wheat, potato. The choice of crop selected by the model allows him to follow this rotation while maintaining the same areas dedicated to the different crops every year.\u00a0 He will have to follow the cropping pattern, that is to say rotate crops on the different farm plots.<\/p>\n<p>For example :<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-4379\" src=\"http:\/\/www.supagro.fr\/wordpress\/modelecoen\/files\/2018\/12\/rotationS_en.png\" alt=\"\" width=\"786\" height=\"254\" \/><\/p>\n<p><a href=\"http:\/\/www.supagro.fr\/wordpress\/modelecoen\/auto-formation\/sequence2\/cours2-des-specificites-du-modele-agricole\/\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-4121 alignright\" src=\"http:\/\/www.supagro.fr\/wordpress\/modelecoen\/files\/2018\/11\/backUnit.png\" alt=\"\" width=\"211\" height=\"66\" \/><\/a><a href=\"http:\/\/www.supagro.fr\/wordpress\/modelecoen\/auto-formation\/sequence2\/cours2-des-specificites-du-modele-agricole\/lecon14\/activite-14a-rotation-des-cultures\/\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-4326 alignleft\" src=\"http:\/\/www.supagro.fr\/wordpress\/modelecoen\/files\/2018\/11\/backStatement.png\" alt=\"\" width=\"191\" height=\"61\" \/><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Optimum cropping pattern is as follows : Crop cropping pattern (ha) Soft wheat 0 Durum wheat 73.333 sugar beet 0 Rapeseed 18.333 Potato 18.333 Barley 0 The income is as follows\u00a0: 173 100\u20ac.
