New wheat varieties are bred at the experimental farms, and thoroughly tested and proved before they are put out to the farmer. In New South Wales they are then grown on farmer's experimental plots. The State is divided into divisions, and in each an inspector supervises the sowing and cultivation of these plots, which are situated on private farms by special arrangement, the farmer carrying out the work and the department finding seed, manure, and supervision, usually near the roadside, where the plots can be seen by district farmers and progress noted. The inspector advises growers generally, while the plots are a silent teacher all the time. They have proved a valuable medium of practical education amongst the farming community, special attention being given to cultural methods. In 1911-12 plots were cultivated in New South Wales in eighty-three districts. In 1911 there were seventy-two farmers' plots in Victoria on which manurial and variety wheat trials were conducted. In the latter State, however, a change has been made, and the majority of these plots have been discontinued, and a commencement made towards a policy of concentration in experimental investigation. It was decided to establish a Central Research Farm at Werribee, on which the initiative with regard to all experimental and research work is undertaken, while other State farms and the Agricultural College will be used as district experiment stations. The work at the Central Research Farm is intended to confer on agriculture the benefits of the most scientific advances by the prosecution of investigations and trials under practical and accurately-recorded conditions concerning problems involved in increasing the agricultural output. Attention will be given to improvement of wheat, soil renovation, fertilising and tillage methods, rotation of crops, &c. The farm is within 18 miles of the capital city, Melbourne, and is easy of access by farmers from all parts of the State. Much of the soil closely resembles in physical character and chemical analysis that of the principal wheatgrowing districts. At Longerenong Agricultural College and the Rutherglen Viticultural College attention is given to the improvement of wheat by systematic selection, crossbreeding and hybridisation in one case, and the fixation and testing of new crossbred wheats in the other. South Australia also has its Government Agricultural College, where extensive wheat experiments are conducted. The college has been of the greatest benefit to the farming community. In that State there are several demonstration and experiment farms established by the State, including the Parafield Wheat Research Station, 170 acres in extent, which is set apart for the raising of high-grade seed wheat for distribution amongst growers, and the raising of new varieties of wheat by crossbreeding and selection.
