The Indian government has undertaken several measures to boost agricultural production. The Green Revolution introduced high-yielding varieties of seeds, increased use of fertilizers and pesticides, and expansion of irrigation facilities. Land reforms such as abolition of zamindari system and consolidation of holdings improved land ownership and utilization. Cooperative societies were promoted to facilitate credit, marketing, and supply of agricultural inputs. The government has launched crop insurance schemes to protect farmers against crop failures due to natural calamities. Minimum Support Price (MSP) ensures fair prices for crops, encouraging farmers to increase production. Agricultural universities and extension services provide training and disseminate modern farming techniques. Modernization of agriculture through mechanization, research, and development has also been promoted.

(ii) Describe the geographical conditions required for the growth of rice.
Rice needs high temperature (above 25°C) and high humidity during its growth period. It requires annual rainfall of 100-200 cm; irrigation is essential in areas of low rainfall. Rice thrives in alluvial soil or clayey loam, which can retain water. It is generally cultivated on lowlands and river valleys, where water stagnation is good. Proper supply of water during the growing season, levelled fields for flooding, and adequate sunlight are important for optimal growth. In India, states with suitable geographical conditions for rice include West Bengal, Odisha, Punjab, Tamil Nadu, and Andhra Pradesh.
