Question

Prior to sowing rice, a legume crop was cultivated and plowed back in the field, why? Explain.

Answer 1

A farming tool called the plow is used for loosening or turning the soil before sowing seed or planting. Plowing was done by oxen and horses before now more modern ways have come up like tractors. It may have a wooden, iron, or steel frame attached with a blade to cut and loosen the soil.

Complete step by step answer:
The leguminous plant possesses nitrogen-fixing bacteria which is a symbiotic bacterium known as Rhizobium. They fix the nitrogen in the soil and the soil is now rich in nitrogen which helps in the agriculture of the crops. Agronomy is the study of particularly on plant and soil sciences. Plowing is done so it can be used again easily for the new crops. If the new crop is sown through the roots of the old crop it cuts off the water supply and many nutrients for the plant which it takes from the soil. People are still working with businesses to find ways to both optimize yields and foster sustainable farming to provide food and fabrics for people to use and their distribution to the market. So, legume crop is cultivated and plowed back before sowing the rice.
Rice is considered a Kharif crop and a very important crop for India. It is grown in rain-fed areas. Also in areas with hot and humid climates with a temperature of 16 to 20 degrees Celsius during the growing season. It requires a temperature of 18 to 32 degrees Celsius during ripening. It needs a flooded field during the growth period.

Note: The leading rice-producing states are West Bengal, Uttar Pradesh, Punjab, Tamil Nadu, Andhra Pradesh, Bihar, Chhattisgarh, Odisha, Assam, and Haryana in the order of largest producing state to smallest producing state.
