2. Befare planting:<br />

a. Establish target yields (depends on variety, growing region, climate).<br />

b. Set water productivity targets (<strong>to</strong>n/million liter).<br />

c. Plan the entire operation from start <strong>to</strong> finish.<br />

These recommendations are provided yearly by NSW DPI <strong>to</strong> every <strong>ric</strong>e farmer in New South<br />

Wales, the primary <strong>ric</strong>e-growing region in Australia. The recommendations are based on data<br />

provided by participating farmers which the Department analyzes <strong>to</strong> find the practices that<br />

result in the highest yield and productivity. <strong>Rice</strong> farmers are free <strong>to</strong> join the program but not<br />

every farmer has <strong>to</strong> do so. Participating means that farmers have <strong>to</strong> provide data about their<br />

<strong>ric</strong>e production <strong>to</strong> the Department and engage in farmers’ group meetings. For instance, the<br />

recommendation that water level be at a depth of 20 <strong>to</strong> 25 cm at microspore stage was arrived<br />

at by comparing the different water levels that participating farmers used and finding that this<br />

water level resulted in the highest yield.<br />

The <strong>Rice</strong>check Recommendations:<br />

1. Land suitability<br />

Key Check: A suitable land for growing <strong>ric</strong>e must be one that has low permeability.<br />

This prevents unnecessary water loss through percolation and seepage. By minimizing<br />

access <strong>to</strong> water sources (irrigation canals or groundwater), considerable water<br />

conservation is achieved. The recommended <strong>to</strong>tal water usage is below 14 <strong>to</strong> 16<br />

million liters per growing cycle.<br />

2. Field layout<br />

Key Check: A <strong>ric</strong>e field <strong>with</strong> a good layout is flat and even. The bunds must be wellconstructed<br />

(no seepage or leakage) and be at least 40 cm in height at its lowest point.<br />

Water channels should be constructed <strong>to</strong> facilitate efficient supply, drainage, and<br />

recycling.<br />

2. Sowing time<br />

Key Check: Sowing should be done during the recommended sowing window for<br />

each <strong>ric</strong>e variety when environmental conditions such as temperature favor seed<br />

germination and seedling survival.<br />
