Abstract:

Ecological Engineering and ecofriendly pest and disease management strategies in paddy is the need of the hour because of reduction in natural enemies population in rice ecosystem due to indiscriminate use of pesticides. Ecological Engineering and ecofriendly pest and disease management strategies in paddy was demonstrated in the farmers’ field as Front Line Demonstration in Nagapattinam district of Tamil Nadu. In the demonstration plot the dead heart symptoms was 3.63% and white ear was 0.86% compared to 13.29% and 2.90% dead heart and white ears respectively in the farmers practices adopted plot. In the same manner the leaf folder damage was also low in the demonstration plots. The pest defender ratio was 0.75:8 in the demonstration plot and it was 4:1in the farmers practices adopted field. The per cent Disease Index (PDI) for blast was 0.73%, PDI for Bacterial Leaf Blight (BLB) was 2.47% compared to 5.12% and 9.51% respectively in farmers practices adopted field. The PDI of false smut was 0.33% in the demo plot and it was 3.33% in the farmers practices adopted plot. In the demonstration plot the highest yield of 56.57 Q/Ha was recorded when compared to only 34.73 Q/Ha in the farmers practices adopted plot. The net return was Rs. 35,540/Ha whereas, in the farmers practices adopted plot the net return was only Rs.9,458/Ha. The benefit cost ratio was 1:1.82 in the demonstration plot and it was 1:1.24 in the non-demo plot.
