Food production methods are crucial to meet the increasing demand caused by a growing population. To address this challenge, techniques like animal and farm management, advanced plant breeding, and technologies like tissue culture are used to boost crop yield and quality.
Animal breeding is a key aspect of food production. It aims to improve animal productivity and enhance desirable traits in the end products.
Traditional farming methods have limitations in increasing food production. Simply expanding fields or better management practices can only go so far in boosting biomass production. Technology, especially in plant breeding, has revolutionized food production by significantly increasing crop yields.
