Pour calculer la densite de semis,
vous pouvez utiliser les formules suivantes

Grains/m2 = (plantes/m2/levee en champ) x 100

Densite de semis (kg/ha) = Densite de semis (grains/m2)/100 x PMG (g)

Quantite de semences (kg/ha) = Densite de semis (grains/m2)/100 x PMG (g)

Dose de semis (kg/ha) = (Nbre grains/m2 x PMG en g) / 100

Le PMG (Poids de Mille Grains) est necessaire pour calculer la densite de
semis. La densite de semis conseillee pour le ble oscille entre 200 et 400 
grains par metres carres, l equivalent, apres prise en compte du poids de 
mille grains, de 120 à 200 kg de semences par hectare.
