Micrometeorological Studies in Rice: A Review

Rice is an important food crop cultivated all over the world and in India. There are different factors such as temperature, relative humidity, rainfall and solar radiation are influencing on rice crop production. Not only these factors, but also, some of the micro climatic factors such as canopy temperature, leaf temperature, soil temperature and stomatal conductance are also influencing on crop production. Microclimate, which refers to the climatic factors in the immediate proximity of the plants it controls and influences the physiological responses of the plants as well as the activities of energy exchange between the plant and its surroundings. It is expected that increased year-to-year yield variability in crop production will result from an increase in the frequency and severity of droughts and floods, as well as from irregular precipitation patterns.In order to promote food security and agricultural sustainability in this changing climate, it is necessary to use such microclimatic alterations in crop production in order to reduce the risk of extreme weather events and increase crop output. This study aims to increase crop output and land productivity through microclimate modification as a demonstration of the effectiveness and efficiency of growth factor utilisation. The detailed description of microclimate and its role with reference to rice crops are reviewed under this chapter.
