10a EXPERBIEXT STATION. [Jan. 



This investigation is now being enlarged to measure the results of treatments and 

 also the effect, if any, of treatments applied at different times, particularly in late fall 

 or winter. 



Market Garden Field Station Project 1. "Manure economy tests." 



Professor Tompson. 



The progress of this work, developed as it was to find an answer to the problem raised 

 by increasing shortage of animal manures, indicates that the amount of manure ordi- 

 narily used by vegetable gardeners may be cut in half, the difference being made up by 

 chemical fertilizers, without loss of crop and in some cases with significant decrease in 

 cost of production. 



Market Garden Field Station Project 5. "Gro\\'th control b}^ means of inter- 

 cropping." 



Professor Tompson. 



ThLs project represents an attempt to better the condition of soils given up to perma- 

 nent onions, through the systematic use of inter-sown cover crops. The records of the 

 year were spoiled, however, because of attack of the onion maggot and the resultant 

 spotted stand. 



Pomology Project 5. "Comparison of cultivation and sod mulch in a bearing 

 orchard." 



Professor Shaw and Mv. French. 



This project, started in the spring of 1921, attempts to find the difference in effects 

 on growth and production between cultivation in a bearing orchard and the use of nitrate 

 of soda in conjunction with a sod mulch. The sod plots were seeded to grass in June, 

 and the application of nitrate of soda was reduced from 300 to 150 pounds per acre. 

 The percentage of bloom was taken on all trees and the percentage of set on certain trees 

 of each variety and treatment, as well as the regular growth and yield records. The 

 trees on the areas seeded to grass (to which nitrate of soda was applied) on the whole 

 bloomed heavier, set a little better and j'ielded considerably more than the trees in the 

 cultivated plots (which received no nitrate of soda). The grass sod can hardly be ex- 

 pected to show any pronounced effect before the 1924 crop. 



Pomology Project 6. "Comparison of clover and grass in a sod mulch orchard." 



Professor Shaw and ]\Ir. French. 



The trees in the sod mulch plot receiving nitrogen have already shown the influence 

 of the fertilizer. Up to date there are no clover residues on the potash and phosphoric 

 acid plot which could have had effect comparable with that of applied nitrogen. It is 

 interesting to note that under the proposed comparative treatments, that is grass plus 

 nitrogenous fertilizer on the one hand as compared to clover with potash and phosphoric 

 acid on the other, the latter system is handicapped at the very start. 



Pomology Project 7. "Test of fertilizers in a sod mulch orchard." 



Professor Shaw and Mr. French. 



This orchard was seeded to grass in the fall of 1921, and the fertilizer application of 

 1921 repeated this year. While no effect of the fertilizer could be seen last year, there 

 was a marked response by the trees on all the fertilizer plots this year as indicated by 

 darker leaf color than that of the check trees. The regular records of growth, bloom 

 and yield have been taken. 



Pomology Project S. "Test of cover crops for apple orchards." 



Professor Shaw and Mr. French. 



This project has been continued as last year, using the same cover crop with similar 

 results. Timothy and redtop mixture was so promising that it was used in two of the 

 larger orchards to try it out on a more extensive scale.
