PLNT 1213 Lecture Notes - Lecture 15: Noxious Weed, Genetically Modified Organism Containment And Escape, Soybean
Document Summary
Physiological maturity: when the plant stops depositing energy in seeds: plant reaches maximum dry weight, dry down after physiological maturity is entirely due to evaporative moisture loss. Harvest maturity: when the moisture content of seeds is appropriate for processing and storage. Small grain maturity: milk (11 16 days after fertilization, soft dough (17 21 days after fertilization, hard dough (21 30 days after fertilization, mature (30 40 days after fertilization) R2-6 reproductive stages of the kernels. Black layer forms when the corn is mature and cuts off nutrients to the seeds. Forages are harvested for hay before they reach physiological maturity. Retain the quality of the crop: don"t introduce contaminates, don"t introduce disease, don"t allow insects or other pests (rodents, don"t cause undue mechanical damage, don"t allow spoilage, don"t allow pesticide residue. Price based on moisture and test weight. Dockages: high moisture, low test weight, foreign material, low protein.
