The summary doesn't really explain what this manga is actually about.
It's about girl who goes to an agricultural school who gets transmigrated to the sengoku period with some modern day seeds and lands before Oda Nobunaga. She is then entrusted with the task of producing a bountiful harvest as the chief of a village that hasn't been able to reach their required amount for a few years now. If she fails, she dies, if she succeeds, she gets rewarded.
The whole idea of "Survive the Sengoku era" isn't really there for me, since she's pretty much given a safe place to stay almost immediately. It's not about survival, it's about farming. Although I guess that should've been obvious if I looked at the meaning of the title in English " A Tale of a Small Town hardship in Sengoku Era - An Agriculture Comic".
