Farmers' Cooperative Experiments. 467 



No. 127. Wheat. — (a) An experiment in selection by individual 

 plants to improve the variety, (b) An experiment in the selection of 

 large heads to increase the yield. 



Note: Detailed plans of conducting the experiments will be fur- 

 nished to interested parties. 



III. HORTICULTURE. 



L. B. JUDSON. 



No. 30. Orchard cover crops. — 3 plats. A comparison of the values 

 of hairy vetch, Canadian field peas, and mammoth clover, in apple, plum, 

 pear, or peach orchard. All plats in cover-crop experiments j4, acre in 

 extent. Keep soil thoroughly stirred from spring until middle of July, 

 when seed should be sown. Seed furnished by the College. 



No. 31. Mulching versus cover-cropping. — x\ comparison of these 

 two methods in the same orchard, to show the effect on yield, color, 

 and size of fruit. This will make an interesting experiment with any 

 kind of tree fruits, but especially apples and pears. This line of experi- 

 mentation is one of the most interesting, important and practical now 

 before fruit growers in this state, and any capable grower can readily 

 obtain valuable results. Particulars sent on application. 



No. ;^2. Spraying experiment. — Compare the effect of ordinary Bor- 

 deaux mixture (4-4-50) with the weaker mixture, (3-3-50), both as to 

 control of scab and amount of spray injury. In mixing the Bordeaux 

 always put in the water between the other two materials. See directions 

 in the recent Spray Calendar. Write for record blanks. 



No. 33. Dipping trees before planting. — Fumigation of nursery stock 

 seems frequently to be either ineffective in destroying insects, or in- 

 jurious to the trees, and it is very desirable to know whether dipping the 

 trees completely in warm lime-sulfur wash, thus insuring destruction 

 of scale, will prove injurious to the trees. Dip both tops and roots in 

 lime-sulfur wash, coating them completely, then plant these trees side by 

 side with untreated trees from the same lot. Write for details. 



No. 34. Thinning fruit. — Conduct tests on early apples, peaches and 

 plums. Write for details. 



No. 35. Strazvberries and raspberries. — Test the varieties, both 

 standard and new. Write for record blanks. 



No. 36. Cabbage. — Testing varieties. Seed furnished by the College. 



No. 37. Pumpkins. — Nearly every farmer grows pumpkins, but the 

 crop is too often small, belated and lacking of uniformity. Here is an 

 excellent chance for a practical application of plant breeding, where in- 

 tensely interesting as well as profitable results may be obtained by any 

 farmer. The method is simply to save seed from pumpkins selected 

 according to the following points: i. Number of fruits to the vine.
