Agronomic Options For Profitable Rice-Based Farming System In Northern Australia, Siva Sivapalan

Books & book chapters

Minimum air temperatures less than 15°C had biggest impact on varietal performance. Cold damage during the months of June and July warrants selection of varieties with cold tolerance for this environment, especially for the aerobic rice system. Ponded water has 4-8°C advantage over the air temperature, thus providing some protection against such cold damage. This has resulted in higher yields under flooded system. Planting dates, varying from late-February to late-May, were found to play a crucial role for plants to escape the low temperature damage at critical growth stages. Among the varieties tested, selected tropical varieties yielded higher than the …

Water Balance Of Flooded Rice In The Tropics, Siva Sivapalan

Books & book chapters

Department of Agriculture and Food, WA staff member authored "Water Balance of Flooded Rice in the Tropics" in the publication Irrigation and Drainage - Sustainable Strategies and Systems’, edited by Muhammad Salik Javaid, published by INTECH, May 2015

Chapter Summary: Excess groundwater recharge rates under irrigated agriculture may lead to problems such as rising watertable, waterlogging and salinity. In irrigated areas, growers may need to manage this water and hence, understanding what leakage is attributed to what crops will become more important. In this study, evaporation, transpiration, and deep percolation losses were estimated for ponded rice culture, using a …

Camballin Irrigation Area : A Summary Of Cropping And Pasture Studies 1958-1970, Phongsak Yuhun

Resource management technical reports

The Camballin Irrigation Area was the first large scale rice growing area in Western Australia. It was hoped Camballin would develop into a highly productive irrigation area. The Department of Agriculture was directly involved in the area between 1958 and 1970. The report summarizes the research carried out during the period which paralleled the commercial operation. The trials were designed to solve the specific cropping problems encountered over the period.

Phosphate Requirements Of Rice In The Ord River Valley, Rijn P J Van, A. L. Chapman

Journal of the Department of Agriculture, Western Australia, Series 4

A three-year experiment on the initial and maintenance phosphate requirements of wet-season rice was carried out at Kimberley Research Station between 1960 and 1963.

Application of 2 cwt. per acre superphosphate as the first application on new land, followed by annual application of 1J cwt. per acre is recommended.

Dry Season Rice Varieties For The Ord River Valley, A L. Chapman, P. J. Van Rijn

Journal of the Department of Agriculture, Western Australia, Series 4

PREVIOUS experimental work at the Kimberley Research Station (Langfield 1961) showed that, in general, indica varieties of rice are best adapted for wet-season sowing and japonica varieties for dry-season sowing.

This article gives the results of three rice variety and time of planting experiments carried out at Kimberley Research Station in the I960, 1961, and 1962 dry seasons. The recommendation is to sow the variety Caloro during May.

Rice Growing In The Ord River Valley, C B. Langfield

Journal of the Department of Agriculture, Western Australia, Series 4

THE first commercial rice crop in the Ord River Valley was planted late in I960 and plans are in hand for some 35,000 acres of land to be subdivided for irrigation settlement by 1964, with rice as a major crop.

Kimberley Research Station : A Progress Report, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

INTEREST in the agricultural potential of the Kimberley region in Western Australia dates from its early exploration and settlement in the last century.

Several farming development schemes were considered for the area, but were never implemented.

This could be mainly attributable to lack of knowledge of agricultural potentialities, limitations of the local environment and ways of exploiting the local environment.

Up to the present the economy of the region is almost entirely based upon the extensive production of beef and to a lesser extent, wool.
