Abstract:
System of Rice Intensification (SRI) paddy was introduced to offset the heavy cost of Traditional paddy cultivation. To decrease the cost of cultivation in Traditional paddy, to increase profits of the farmers in rice cultivation by decreasing the use of fertilizers, pesticides and minimizing water use by scientific water management in the face of labour scarcity, SRI paddy was introduced in Madagascar. In Traditional paddy the spacing of 20x15cms was followed and 20 days seedlings were used, and whereas, in SRI paddy cultivation, the wider spacing of 25x25cms was followed and by 8-12 days seedlings were used. Although large number of labour were needed for weed management in Traditional paddy, minimal labour was required for weed management in SRI paddy because of using weeders and machinery for weed management.
