This agricultural field pertains to the study of the effects of insects on forests and forest products, as well as the development of solutions to protect forest trees from significant damage. It involves an in-depth examination of the ecological interactions between insects and forest ecosystems and the impact that these interactions have on forest health and productivity.
This branch of agriculture involves the study of insects for legal purposes, with a focus on the use of insects to determine the time and location of human death. It involves an in-depth examination of the ecological interactions between insects and decomposing human remains, and how this can be used to provide critical information for forensic investigations.
6. Seed science:
This agricultural branch is concerned with the study of the structure of seeds and their growth habitats, starting from fertilization, embryonic development, and subsequent growth into a mature plant. It is closely related to the fields of biotechnology and botany and involves an in-depth examination of the genetic and physiological mechanisms that regulate seed development and growth.
7. Crop Physiology:
This agricultural field pertains to the study of the functions and responses of plants to various environmental conditions, including factors such as temperature, water availability, nutrient levels, and atmospheric composition. It involves an in-depth examination of the physiological and biochemical mechanisms that regulate plant growth and development in different environmental contexts.
8. Plant Protection:
Plant protection refers to the various methods and techniques used to protect plants from pests, diseases, and other forms of damage, and to ensure their optimal growth and productivity.
