Question

Punjab is known as the food granary of India growing most of the cereal and cash crops but is facing declining crop yields and poor soil conditions. It is one of the biggest exporter of rice and cotton crops.

1. What climatic conditions favour rice growth in the above-mentioned area?
2. What is the difference between cereal and cash crops? Can a cereal be a cash crop?
3. Suggest the sustainable agricultural practices to improve soil fertility.

Answer 1

1. Climatic conditions favoring rice growth in Punjab:
   1. Temperature: Rice requires a temperature range of about 16-20°C during flowering and 18-32°C during ripening.
   2. Rainfall: It needs a high amount of rainfall, typically 150-300 cm.
   3. Soil: Clayey or loamy soils with an impervious subsoil layer that retains water are ideal for rice cultivation. Punjab, being one of the leading rice producers, meets these conditions with its climate and soil, supporting rice cultivation successfully.
2. • Cereal crops are staple food crops grown primarily for human consumption, like rice, wheat, maize, millets.
   • Cash crops are grown mainly for sale and commercial purposes rather than for local consumption, examples include cotton, sugarcane, and cash-producing cereals.
   • Yes, a cereal can be a cash crop. For example, rice in Punjab is both a cereal and a major cash crop because it is widely grown for export and commercial sale, not just for local food consumption.
3. Sustainable agricultural practices to improve soil fertility in Punjab:
   1. Crop rotation, especially including pulses which fix atmospheric nitrogen and enrich soil fertility.
   2. Use of organic manure and compost to increase humus content and soil nutrients.
   3. Prevent soil erosion by contour ploughing, terrace farming, and shelter belts.
   4. Rainwater harvesting and groundwater recharge to maintain soil moisture.
   5. Reduced use of chemical fertilizers and pesticides to prevent soil degradation.
   6. Promotion of organic farming practices to maintain long-term soil health and fertility.
