Agronomy is the core subject of agricultural sciences. A strong foundation for agricultural education emerges by understanding the principles of Agronomy. Majority of the Students who join for the degree programmes in agriculture universities are never exposed to the crops and crop production aspects.The beginner’s to agriculture needs to be introduced the meaning, scope and principles of agronomy. With this back ground and keeping in mind the common syllabus prescribed by the Dean’s committee for agriculture education in the country efforts are made to compile and present the information on introduction to agronomy, agriculture, meaning, scope and importance, history of development of agriculture, agricultural education and research in the country and elsewhere, factors affecting plant growth, manures and fertilizers, principles of agronomy viz. soil management, crop management, weed management, management of problematic soils, cropping systems, selection of planting materials, their treatment in simple language. At the end of each chapter subjective and objective questions are provided for practice. The author hopes that this book will be useful for the students for learning and for the faculty for teaching the course “Fundamentals of Agronomy” for the undergraduate degree programme in the Agricultural Universities.
