Optimal agriculture: maximum yield with minimum environmental impact
Publications by the Food and Agriculture Organization http://www.fao.org/documents/card/en/c/ca9692en of the United Nations would be a good place to start as they are freely accessible. There are plenty of articles looking at crop yield of different production methods and different management techniques. You may consider subscribing to a journal, like Agronomy https://www.agronomy-journal.org/, or CAB Abstracts https://www.cabi.org/publishing-products/cab-abstracts/ as those would contain most of the subject material you're looking for. Those would also contain information on optimizing food production under resource constraints. Happy researching!
