Technologies des semences

Les semences ont naturellement leur place dans presque toutes les entreprises ayant un rapport avec le développement agricole. Les graines de la plupart des plantes alimentaires sont petites et, de ce fait, sont plus faciles à être transportées et peuvent être expédiées sur de plus longues distances que les boutures végétatives. Pour l'agriculteur, les semences représentent la promesse d'un approvisionnement continu en nourriture.

Comme pour tout outil de développement “, ” cependant, les semences peuvent être mal utilisées. Par exemple, la distribution de semences mal entreposées ayant un taux de germination faible pourrait exposer les agriculteurs à un risque de mauvaise récolte.
