POTATO EXPERIMENTAL FIELDS. 191 01 1. 



G. Seymour, Potato Expert. 



During the season 1910-11, the experunents in connexion with potato 

 culture were carried out at Broadford, Cavendish, Cheltenham, Colac, 

 Daylesford, Dean, Leongatha. Romsey and Tourello. 



The operations at Cheltenham were designed to further test the value 

 of sprouted seed for early market, and also to test the effect of various 

 dressings of artificial manure in combination with stable manure. In both 

 respects the results were the most satisfactory of the three years' series, 

 proving beyond doubt that the yield can be largely increased by this method 

 of treating the seed ; and, what is of t'(]ual importance, a much cleaner and 

 more marketable sample is obtained. The returns of this field will be 

 found in the Journal for March last. 



The fields at Broadford, Cavendish, Colac, Leongatha and Tourello 

 were variety tests, combined with artificial manure experiments. Table I. 

 shows the design of the plot and the manurial dressings at Broadford. 

 Colac, Leongatha and Tourello. It was intended that Cavendish plot 

 should be on the same plan; but, owing to a letter of instructions mis- 

 carrying, it was slightly altered. The results of this plot are very instruc- 

 tive, both with regard to \arieties and to manures.

Broadford Plot. 



This plot was planted on the 24th and 25th November, with thirteen 

 varieties of potatoes, including early and main crop. On reference to 

 Table II. it will be seen that nine varieties were so badly affected with 

 Blight that no returns were obtained from them. 



The varieties marked "nil" and 

 records could be obtained.
