This looks like a problem related to agriculture or biology, possibly about calculating yield under certain conditions. However, the text is in a language I don't fully recognize and contains some potential OCR errors. To provide an accurate answer, I need a clear translation of the problem statement and potentially clarification on the terms used.

If you can provide a translated and corrected version of the text, I would be happy to help you solve it!
