One plot was unmanured and planted with cut potatoes, and in the last 
plot, also unmanured, the potatoes were planted whole. —

POTATO EXPERIMENTS IN CHESHIRE. re. 
A report has recently been issued on the potato experiments which have a 1 
carried out at the Agricultural and Horticultural School belonging % ae 
Cheshire County Council, England. The year 1899 is the fourth yeu’ | 
succession in which this class of experiment has been undertaken, as it1s 1° 
that this continuance is necessary to verify previous results or otherwise. ~~ 
objects in view have been :— ve i 
1. To test the productiveness, character, and quality of a considera’) | 
number of varieties, especially new varieties, a small quantity of each belle | 
planted. , tl | 
2. lo show more thoroughly on a large scale the characteristics, yield, # He | 
cooking quality of those varieties which gave the best results in the prev" J 
year’s trials. 
3. To test whole sets versus cut sets. 
4, To try the effect of sets of different sizes and weights. ried | 
5. To see if artificial manures have much effect upon the yield when apP” | 
alone and in conjunction with farmyard manure. the | 
6. To try the effect of different nitrogenous and potassic manures 0? 
yield and size of the tubers; also on the cooking quality of the tubers. 
7. To see whether it is better to apply nitrate of soda at the # 
planting or as a top dressing two months later. 
8. To mark the effects of disease on different varieties. anki | 
The report contains a very valuable series of tables, with various ren he | 
on them which are worth studying by Australian potato-growers. 
conclusions arrived at are briefly summed up as under :— and 
1. There seems to be very little difference between planting whole sets out 
cut sets, but, if anything, the average results of the last four years are 10 fay 
of whole sets. 
2. That large seed is more profitable to plant than small seed. cen 
3. That an artificial manure containing nitrogen, phosphoric acid, i ia 
potash in suitable proportions will increase the yield considerably ov" | 
manure. ; sficitl 
4. That farmyard manure will produce much better results than at aft 
manures alone. This is probably due to the mechanical influence that farm" 
manure has upon the soil. hates 
5. That the best results are again obtained from 3. cwt. superphosP art 
1 cwt. sulphate of ammonia, 1 ewt. muriate of potash, and 15 tons of farmy™ 
manure. nig Tae 
6. That manures have a considerable influence upon the size and 00” © 
quality of the tubers. (oa 
7. That sulphate of ammonia seems to be the best form in which 10 a 
nitrogen to potatoes. i of 
8. That muriate of potash produced better results than either kal" 
sulphate of potash. cel 
9. The yield per acre this year is less than last year’s in almost © 
variety of potato tried.
