Discuss the climate and soil requirements and cultural practices followed in rice.

Rice (*Oryza sativa*) is a staple food crop and one of the most important cereals cultivated across the globe, especially in Asia. Its successful cultivation is highly dependent on appropriate climatic and soil conditions, along with well-planned cultural practices that ensure optimal growth, yield, and quality.

Rice is a tropical and subtropical crop that thrives in warm and humid climates. It requires a high temperature throughout its growing period, with an optimum range between 25°C and 35°C. Temperatures below 20°C during critical growth stages such as germination, tillering, and flowering can significantly reduce yields. Rice also demands a substantial amount of water; it is well-suited to regions with annual rainfall between 100 to 200 cm. Rainfall should be well-distributed during the growing season, particularly during the transplanting and reproductive phases. In areas with insufficient rainfall, irrigation is essential.
