Consider the following statements:

System of Rice Intensification method was discovered in Madagascar.

Fish- rice farming method helps to reduce methane emission.

Direct seeding of rice method aims to sow short duration varieties.

Which of the statements given above are correct?

Question

System of Rice Intensification method was discovered in the 1980s in Madagascar. In this method, fewer seeds are planted in the field in a well-spaced-out manner. Organic manure is used for fertilizing the fields. Instead of continuously maintaining flooded conditions, the crops are subjected alternatively to dry and wet conditions. The method increases the crops’ resilience to floods and droughts while increasing the yield by 20% and reducing water use. The method works by reducing competition among the plants and improving oxygen supply.
Fish- rice farming method: In this method, fishes are reared in the flooded rice fields. These fishes reduce methane emission from the rice fields and act as additional income source for the farmers apart from adding nutrients to the soil. This reduces dependence on pesticides and fertilizers.
DSR is direct seeding of rice in which seeds are sown in the field rather than by transplanting seedlings from the nursery. It aims to sow short duration and high yield varieties. It is done through DSR machines which are used for planting seeds of rice directly into the fields.
