Detail:

Farmers use an inter-cropping technique to avoid excess thermo conditions in paddy, due to use of green manure, and enhance water retention capacity of soil.For the wetland paddy crop, the twigs and leaves of nochi(Vitexnegundo), ponavaram(Cassia auriculata), kolunchi or kaaval(Tephrosiapurpurea), (Ipomoea fistulosa), veppalai(Wrightiatinctoria), and Calotropis are used as green manure. Farmers have learnt that, if the leaves of (Wrightiatinctoria) and Calotropis are used in excess, a disease called vemputtaioccurs leading to failure of the crop to bear grains. This is caused due to the excess heat generated by application of this green manure. In order to prevent this excess thermo condition in paddy crop, these plant leaves are applied in the paddy nursery, where they do not affect the seedlings.In red, sandy soil the water requirement of paddy is higher and farmers have to increase the frequency of irrigation in the paddy fields. Some farmers, in order to reduce the frequency of irrigation, incorporate into the soil, plants of Ipomoea fistulosa which, while rotting, enhance the water retention capacity of soil.
