Transplanting: Use 18-day-old seedlings and soak the roots in 12% concentration of carbofuran solution for 12 to 24 hours before transplanting; transplant 2-3 seedlings/hill at 20 cm x 20 cm spacing in straight rows. 1-2 DAT: Apply carbofuran granules at 0.5 kg a.i./ha or diazinon at 1.0 kg a.i./ha 4-5 DAT: Apply 0.8 kg a.i./ha 2.4 D IPE G 3.2% if 2-3 cm depth of water is present in the paddy 6-8 DAT: If field is flooded and 2,4 D IPE G 3.2% cannot be applied at 4-5 DAT, apply butachlor or benthiocarb at rate of 1.5 kg a.i./ha 15-20 DAT: Spray 2,4 D IPE EC 48% or MCPA liquid herbicide at 0.8 kg a.i./ha if granular herbicide cannot be applied; handweeding of field if necessary to remove weeds that escaped herbicide treatment. 20 DAT: Broadcast carbofuran granules at 0.5 kg a.i./ha or 1.0 kg a.i./ha diazinon if there is standing water in the paddy or spray insecticides to control stemborers and green leafhoppers. 20-25 DAT: Broadcast 100 kgs ammonium sulfate 21% N as topdressing at panicle initiation. 20-45 DAT: If there is 10% or more deadheart, apply 0.5 kg a.i./ha of carbufuran. 45 DAT: If there is 10% or more deadheart, apply 1.0 kg a.i./ha of carbufuran. 50-55 DAT: At milk stage, spray insecticides to control rice bugs if there are more than 5 insect/m 2 . 85-90 DAT: Harvest the crop.

Reason why recommendations should be followed Recommended actions or management practices Expected outputs from correct application of the recommended action Principles of IPM and INM were included in RiceCheck for respective crop management areas International Year of Rice 2004 Box 2. Guidelines for Crop Establishment and Crop Nutrition in the Australian RiceCheck (Lacy et. al., 1993) CROP ESTABLISHMENT Reason: Adequate plant population is the first step required to increase yield. Recommended Actions: Undertake major field layout improvement prior to winter. Start ground preparation early enough to ensure sowing on time. Land surface should be level and uniform enough to suit sowing method. Depending on variety, field layout and soil conditions, sow 125 kg seed/ha when aerial sowing and 135 kg seed/ha when drill sowing. KeyCheck or Expected Outputs: Achieve 150 to 300 plants/m2 established through permanent watering at 25 days after seeding. CROP NUTRITION: Reason: Split Nitrogen Strategy - two steps which are important to high yields.
Recommended Actions: Apply sufficient pre-flood nitrogen to achieve optimum growth at panicle initiation, apply phosphorus if a deficiency is indicated by paddock and/or soil test, and top dress nitrogen at panicle initiation based on shoot counts and NIR analysis using the Rice NIR Tissue Test. KeyCheck or Expected Outputs: At panicle initiation the Amaroo, Bogan, Illabong and Jarrah (rice varieties) should have 700 - 1100 shoots/m 2 and a leaf nitrogen content (NIR) of 1.2 - 2.2% N; while the Pelde, Doongara, Goolarah, YRF9 and YRL34 (rice varieties) should have 500-900 shoots/m2 and a NIR 1.2 - 2.0%.

Noted that the situation of global rice production calls for efforts to enhance the productivity and efficiency in rice production Observed that there is still a large yield gap and the closing of this gap could substantially increase the productivity of irrigated rice production systems, and that the effective closing of the existing yield gap requires integrated systems approach Identified the Australian RiceCheck system as a potential tool for closing yield gap and for increasing productivity and efficiency in irrigated rice production International Year of Rice 2004 CONCLUSIONS FAO Programme on RiceCheck Initial results demonstrated that the modified versions of the Australian RiceCheck systems are promising for closing yield gap and increasing the productivity of irrigated rice production in developing countries. They also indicated that potentially, the RiceCheck system can be updated for achieving the rice production that respects the environment, once environmental indicators (e.g., level of
pesticides in water, content of cadmium in rice grain, etc.) are made available by research. FAO will continue to collaborate with member countries and all stake-holders concerned in the development and dissemination of RiceCheck systems.
