Plot 3.—Experiment in green manure. ‘Two plots have been 
laid down for this work—one of currants, and one of 
sultanas. The currant plot is on clay soil, and the sultana 
plots on grey loam (mallee). 
Different varieties of leguminous plants will be used 
(peas, beans, vetches, bersium), and results will be judged 
by yields and by a chemical analysis to show nitrogen 
content of the soil at different periods of the year. 
Plot 4.—This plot is devoted to methods of planting. Three 
methods have been used comparatively :— 
_(a@) Vine planted with a probe, without digging. 
(b) Land subsoiled, and vines planted in hole dug 
with spade. 
(c) Land ploughed 6 inches, and planted in hole dug 
with spade. 
Comparison of these plots would be made by noting 
disposition of the roots, the growth of the vines, and by 
yields. 
Plot. 5.—Test for best spacing of vines. A plot has been 
established with variation in distance between the rows, 
and between the vines in the rows. Plots vary from 12 
by 12 to 9 by 6. 
Results will be judged by amount of crop, evenness of 
ripening, and freedom from disease. 
Plot 6.—For determination of amount of irrigation water 
which gives best results. These investigations will be a 
combination of laboratory and field work, and will aim at 
showing the rate of disappearance of water from land on 
which vines are grown, and the amount of soil water neces- 
sary to give continuous growth without checks. LKesults 
bearing on the best spacing for irrigation furrows, the 
length of periods between irrigations, and the best time 
for irrigations should be obtained. 
Plots 7 and 8.—These are still in the nursery stage. 
Phylloxera-resistant cuttings are being struck, and experi- 
mental work to determine which of these stocks are best 
suited to our field grapes will follow. 
The methods of establishing vines on resistant stock will 
be demonstrated. Should Phylloxera come to this district, 
we should know :— 
(a) Which of the Phylloxera-resistant stocks are best 
suited to sultanas, currants, and gordos. 
(b) What are the most efficient methods of establish- 
ing a vineyard locally on resistant stock. 
(c) Which of the varieties are best suited’ to different 
classes of land. 
(d) Which of the varieties will thrive best in land 
affected by salt.
