Answer 2

Answer:

The three conditions for the successful cultivation of rice are:-

1.surface

2.fertilizers

3.labour

1.Surface:

Unlike other crops, paddy needs a level surface to enable the fields to be flooded at least during the growing period. It’s ideal habitat is therefore in the great alluvial deltas and river basins of the world: the Ganges, Siking, Yangtzekiang, Irrawaddy, Menam Chao Phraya and Mekong, where there is practically no gradient.

2. Fertilizers:

Paddy requires three essential plant nutrients: nitrogen, phosphorus and potassium. Most paddy lands have a moderate quantity of such nutrients, but if they are deficient, organic manure or artificial fertilizers have to be used.

3.Labour:

Paddy cultivation is extremely labour-intensive, therefore, requires more labour in comparison to other cereal crops. Labour is necessary for: preparing the field, weeding, sowing, transplanting, manuring, harvesting, threshing, winnowing and milling. For rice cultivation large number of cheap labour is required.
