ence of about 20 bushels per acre between the highest- and lowest-yielding 

 varieties. Of those tested, Erban and V^anguard, two Canadian varieties, 

 and Upright, a variety developed in the States, rank highest in yield for 

 this experiment. 



Some of the newer disease-resistant strains of oats have been intro- 

 duced during 1944, along with the three high-yielding varieties mentioned.

Silage and Field Corn Trials 



Corn variety tests have been carried on for about eight years on the 

 W'henal Farm in Greenland. Each variety has been replicated three times 

 and yields determined, based on the dry matter and moisture percentage 

 obtained from randomized samples dried in the steam-heated drier. 



1. Corn for Grain 



Twenty-two varieties and dent hybrid strains of corn were planted on 

 May 21, 1943. In each case, the three randomized plots were thinned so 

 there were three plants in each hill. On October 7, the ears of each repli- 

 cation were picked and weighed. Samples in triplicate of 12 ears each, 

 picked out at random, were dried to a uniform moisture percentage of 

 about 8 per cent which were used for calculating the yields on an equal 

 basis. 



"New Hampshire 500" used as a check with the Minhybrids 700 and 

 800 series again gave good yields of mature grain corn. The results for 

 1943, as well as for 1942, are summarized in Station Circular 67, "Small 

 Grain and Corn Variety Tests," February, 1944. 



2. Silage Corn 



In 1943, twenty-two silage corns, including several new hybrids, were 

 planted on May 21. Perfect stands were obtained by heavy planting and 

 then thinning to three plants per hill. Twelve hills of each replication 

 were cut and weighed on September 13. One hill of each replication was 

 bagged and dried to a uniform moisture percentage in order to obtain the 

 per cent dry matter and yield per acre. 



Of the new hybrids Ohio 66 again led in silage of dry matter per 

 acre, but Ohio 66 has been discontinued due to cost of seed. This goes to 

 show that new strains may yield well but they may not stay in production. 

 In the Agronomy corn trials over a period of eight years Lancaster Sure 

 Crop. Cornell 29-3, and W^est Branch Sweepstakes have been the most 

 consistant producers of good yields of corn silage. In 1943, a season of 

 low rainfall, all varieties produced over 9,000 pounds of dry matter and 

 over 21 tons of green weight per acre.

Advanced Alfalfa Nursery Trials 



The advanced alfalfa nursery plots were seeded in 1941 on the Whenal 

 Farm, Greenland, New Hampshire. Each of the six varieties was repli- 

 cated five times. In 1943, three cuttings were made as in 1942 and the 

 per cent dry matter was calculated from randomized samples dried in the 

 steam-heated drier. 



A-145 New Jersey, now named "Atlantic," came up from second 

 place in 1942 to first place in 1943 with a yield of 2.98 tons per acre.
