Biasi system of land preparation in Bastar

PrintPrintSend to friendSend to friend

1. Biasi is a set of cultural operations traditionally practiced in direct seeded rice.

2. In this operation, the field is ploughed by an indigenous plow in standing water 30–50 d after emergence.

3. Bullock plowing often followed planking and chalai (thinning and distribution) operations.

4. This system is very popular in the eastern region of India. The effectiveness of the system greatly affects yield. Often, operation is delayed because there is less rain to flood the field.

5. The post-biasi operation, which is done to redistribute seedlings, has high labor requirements and is costly. The other major drawbacks are high plant mortality (38–40%) and heavy weed intensity.
