Weather is a basic input for agriculture. It affects the agricultural planning in a big way starting from land preparation to harvesting, processing and transportation. Thus, climate and weather may be considered as the most critical factor determining the sustainability of agricultural systems. Agrometeorology is now recognised as a full-fledged discipline and recommended as a core subject in the curriculum of the agricultural universities. The book covers the syllabus of the course 'Introductory Agrometeorology and Climate Change' meant for undergraduate students of agriculture, horticulture and forestry. Contents: 1.
