NYS Cannabis sativa L. Production Manual

The New York State Cannabis sativa L. Production Manual is intended to provide current data and findings about sustainable hemp cultivation to growers and members of the Cannabis industry to achieve a high-quality, profitable, and compliant yield. Cannabis sativa yields are used for the development of hemp-based cannabinoid products, fiber, grain, and medicine. As research and knowledge about hemp and, in general, the C. sativa plant increases, this manual will be updated to include new information. The perspectives of the manual authors are largely, but not exclusively, directed to the industry in New York State. 

The manual also includes information about the regulatory environment around hemp in New York and the United States, a description of C. sativa cultivation, information about testing and grading, as well as tips on how to produce a crop that meets international environmental and labor standards. Our objective is to help growers maximize yield, quality, profitability, and product integrity while maintaining compliance.

New York Urban Farms Sustainable Pest Management Fact Sheet Series

Cornell Cooperative Extension has partnered with dozens of urban farms across New York State to demonstrate and evaluate sustainable pest management strategies. Together with farmers, we found success using control methods that prevent or reduce crop losses through exclusion strategies, crop timing, host resistance, the introduction of beneficial organisms, and more. Regardless of management strategy used, common requirements for success include a knowledge of the pest and disease complex, preventative deployment and commitment to the process. The New York Urban Farms Sustainable Pest Management Fact Sheet Series includes case studies highlighting pest management techniques that New York urban farms have found valuable.
