Climatic Requirements for Fruit Cultivation | Temperature, Rainfall & Climate Factors Explained Fruit cultivation is an important branch of Horticulture that deals with the growing of fruit crops for food, nutrition, and economic benefits. Climate plays a vital role in determining the growth, flowering, fruiting, and quality of fruits. Every fruit crop has specific climatic requirements such as temperature, rainfall, humidity, sunlight, and wind conditions. If the climate is favorable, fruit plants grow well and produce high-quality fruits. However, unfavorable climatic conditions may reduce yield and quality. Understanding the climatic requirements of fruit crops is essential for farmers, agricultural students, and horticulture enthusiasts. Proper knowledge helps in selecting suitable fruit crops for a particular region and adopting the right cultivation practices.
