Question

list advantages of levelling of field​

Answer 1

Answer:

There are many advantages

Explanation:

Effective land leveling reduces the work in crop establishment and crop management, and increases the yield and quality. Land leveling increases yield to a large extend because it improves weed control. Improved water coverage from better land leveling reduces weeds by up to 40%.

1. Higher yield

Good field leveling increases the rice yield considerably. In two experiments conducted at different localities, a strong correlation was found between the levelness of the land and crop yield. (see chart)

2. Better weed control

Land leveling increases yield to a large extend because it improves weed control. Improved water coverage from better land leveling reduces weeds by up to 40%. This reduction in weeds results in less time for crop weeding.

A reduction from 21 to 5 labor-days/ha is achieved. This represents a reduction of up to 16 person-days per hectare � a 75% decrease in the labor required for weeding.

3. Larger farming area

Good land leveling enables larger fields. Larger fields increase the farming area and improve operational efficiency. Increasing field sizes from 0.1 hectare to 0.5 hectare increases the farming area by between 5% and 7%. This increase in farming area gives the farmer the option to reshape the farming area and can reduce operating times by 10% to 15%.

4. Faster seeding/Less work

Leveling reduces the time needed for transplanting and for direct seeding. Land leveling provides greater opportunity to use direct seeding. The possible reduction in labor by changing from transplanting to direct seeding is approximately 30 person-days per

5. Better use of water

Rice farmers using animal or 2-wheel tractors rely on water to accumulate in the field before starting land preparation. The higher the difference between the highest and lowest portions of a rice field, the more water is needed to achieve complete water coverage. Good leveling may reduce total water requirement to grow the crop by up to 10%.

Answer 2

Answer:

Explanation:

the main benefits of levelling are:

improved crop establishment,

even water coverage of the field,

even crop stand and maturation,

reduction of weeds by up to 40 % (thereby a 75 % decrease of labour required for weeding),

increase of farming area by 5-7 %,

reduction of farm operation times by 10-15 %,

within rice production, the possibility of changing from planting and transplanting to direct seeding which results in reduced labour of 30 person-days per ha, and

average yield increase of 10- 20 %
