Doyenne du Comice: A variety of dessert pear, originating in France. The fruit are very round and mature slowly. Doyenne du Comice pears are prized for their sweet flavor and juicy texture.

defoliate: To make the leaves fall off a plant, especially by using a herbicide or as the result of disease or other stress. Defoliation can be a management tool or a sign of plant stress. Farmers should monitor crops for signs of disease or environmental stress and take appropriate actions to mitigate defoliation. Using defoliants judiciously can help manage crop canopies and improve harvest efficiency. Regular scouting and timely interventions will ensure healthy crop growth and productivity.

dumping: The disposal of waste or the sale of agricultural products at a price below the true cost to get rid of excess produce cheaply, usually in an overseas market. Farmers should be aware of regulations and market conditions to avoid the negative impacts of dumping.

dewlap: A fold of loose skin hanging from the throat of cattle. Dewlaps can be an indicator of breed characteristics and health status. Farmers should monitor the health and hygiene of dewlaps to prevent infections and ensure animal welfare. Proper care and management practices will contribute to the overall health and productivity of livestock.

dehiscence: The sudden bursting of a seed pod, fruit, or capsule when it is ripe, allowing the seeds or spores to scatter. Managing dehiscence involves understanding plant growth patterns and optimizing harvest timing. Farmers should monitor crops closely and use appropriate techniques to collect seeds and maximize yields. Knowledge of dehiscence can also aid in breeding programs and crop improvement efforts.

digestibility trial: A test to measure the digestibility of a known food by recording the weight of food eaten and then excreted. Conducting digestibility trials is important for evaluating the nutritional value of animal diets. Farmers should work with veterinarians and nutritionists to perform digestibility trials and develop balanced and nutritious diets for their livestock. Understanding the results of digestibility trials will aid in effective feed management and improved farm productivity.

digestive enzymes: Enzymes which speed up the process of digestion. Providing digestive enzymes can improve the efficiency of nutrient absorption in livestock. Farmers should work with veterinarians and nutritionists to include digestive enzymes in animal diets as needed. Understanding the benefits and applications of digestive enzymes will aid in effective feed management and improved farm productivity.

digestible: Able to be digested. Glucose is an easily digestible form of sugar. Providing digestible nutrients is essential for maintaining the health and productivity of livestock. Farmers should work with veterinarians and nutritionists to ensure that animal diets are highly digestible and promote optimal health. Understanding the importance of digestible nutrients will aid in effective feed management and improved farm productivity.

dam: The mother of an animal. Knowing the lineage and health of the dam is important for breeding programs and offspring quality.

drill coulter: A coulter that makes a furrow for sowing seed. Drill coulters are essential for precision planting, helping to create uniform seed rows and improve crop establishment.
