This NSW DPI Primefact sheet is and overview of the guidelines to take into consideration when considering draining rice. The fact sheets covers areas such as the variety selection and time of sowing, the water management after flowering. It covers the key factors such as field layout, crop nitrogen, time when crop maturing , sowing methods, time of draining, grain development stages soil types and who and where to contact for further information.
This DPI NSW rice field guide covers pests such as Bloodworms, Water snails, Leafminers, Aquatic earthworm, Common armyworm, Sugarcane and maize stemborer Tadpole shrimp , Yabbies, Locusts and grasshoppers Exotic pest threats. It also covers diseases such as Damping off, Stem rot, Downy mildew Cochliobolus leaf spot Sheath spot Aggregate sheath spot Glume blotch, Sheath brown rot Sheath and glume rot Exotic disease threats. Finally is gives details of weeds such as Impact of sowing method Integrated weed management Barnyard grasses, Silvertop grass, Dirty Dora Starfruit Arrowhead Alisma, Water plantain Sagittaria, Umbrella sedge Water couch Cumbungi (bulrush) Rushes, Common spike rush Bolboschoenus Alligator weed Water primrose Chara and Nitella. Each pest, disease and weeds has its lifecycle, crop damage, management, origins and key characteristics described to assist farmers.Read More
This NSW DPI fact sheet gives information in regard to Armyworm in rice. Seasons 2011/12 and 2012/13 saw significant impact of armyworm on rice with estimates of 60% of crops in Murray Valley requiring spraying treatment. This fact sheet covers in information on the biology and management of armyworm in rice. It also gives guidelines for crop monitoring and contact details for further information.
This IREC Farmers Newsletter reports on the continuation of the permanent beds for sustainable cropping which has been running since 2000. The reports for 2005, 2006, and 2007 are included in this library. The report covers 05/06 results, weed control, rice growth and yields, irrigation and fertilisers. This report concluded that high yields of wheat were achieved in 2005. This was seen on both raised beds and flat layouts – in a year without rainfall- induced water logging in winter or spring. It was also seen that the rice yields on both raised beds and flat treatments were excellent during an exceptional rice growing season. It was acknowledged that the rice yield from the bed systems is as high as that from conventional flat systems where rice is grown using permanent flooded conditions and deep water is applied during the early microspore stage.Read More
This RIRD report presents the results of the project using raised beds on rice farms - sustainable cropping systems on rice farms. The project was an experiment evaluating a new irrigation layout for rice and other crops. The targeted audience included rice and grain growers within rice based farming systems, advisory and commercial agronomists, irrigation surveyors and designers, irrigation distribution companies and, land and water management plan implementers operating in these areas. The project aim was to increase the sustainability, resource use efficiency, yield and profitability of rice-based cropping systems through improved soil, water and nutrient management using permanent raised bed systems. The method undertaken was a large replicated field experiment conducted at Coleambally Demonstration Farm, NSW. Double cropping with side-by-side demonstration of permanent raised beds (including sub surface drip irrigation) and traditional ‘flat’ layouts were investigated. Three broad types of crop sequence were selected to include both traditional and novel crop sequences (double cropping with both winter and summer crops each year). Different crop options were included within each broad sequence. In addition to this experiment the project estimated the potential benefits and costs involved in switching over to permanent raised beds over common irrigation layouts of rice based farming systems within a benefit cost framework. The key findings demonstrated that where irrigation supplies are sufficient rice can be grown in close rotation with winter cereals and other summer crops on raised beds. This demonstrated that the adoption of raised beds in terraced, bankless channel layouts provides an opportunity for this to occur. Barley/soybean double cropping was successful on raised beds in rotation with rice. With the technology available it is viable from a financial perspective and as seen in the benefit cost analysis revealed that there are significant benefits in switching to permanent raised beds in terraced, bankless channel layouts.Read More
Monthly water budgets to compare crop water requirements and available allocations are very important. If crop needs are likely to exceed supply then decisions about buying extra water or reducing the area of rice by draining must be made. The information can help rice growers calculate their water needs and compare this with available supplies.Read More
The project reviews and updates the publication Rice Growing in New South Wales, which was produced in 1984, bringing together all the current understanding and knowledge behind rice growing practices and recommendations. The publication does not attempt to provide information on 1tow to' but rather 'why' recommendations are given.Read More
