 come popular with the farmers as a whole.

Silage and Field Corn Trials 



1945 Silage Corn. Thirty varieties and hybrids were planted on 

 May 25, 1945, at the Bunker Farm. Each seed lot was replicated three 

 times in 18 hill rows with each hill thinned to three plants. West Branch 

 Sweepstakes, a high-yielding, open-pollinated variety, and Cornell 29-3, 

 an excellent double-cross hybrid, were used as the standard checks. 



On September 12, 1945, the corn silage was harvested. Twelve hills 

 of each replication were weighed for the calculation of the green weight 

 acre yield. One hill of three plants of each replication was bagged and 

 dried to obtain, on a uniform basis, the calculations of the yield of dry 

 matter per acre. 



In this tenth year of silage trials, both West Branch Sweepstakes and 

 Cornell 29-3 gave good returns. Massachusetts 62, a new hybrid, showed 

 considerable promise. Due to one poor replication, Ohio K-24, well up 

 a year ago, dropped down. 



1945 Gram Corn. Forty varieties and hybrids in three replications 

 of each were planted, May 25, 1945, at the Bunker Farm. Each replica- 

 tion was made up of 18 hills and each hill was thinned to three plants. The 

 standard checks were as follows: two local unnamed Flint varieties, two 

 Dent Flint hybrids (Maine "A" and Maine "B"), and two Dent varieties 

 (Cornell 11 and New Hampshire 500). 



The ears were snapped off on October 19 and 20, 1945, and the 

 weights of each replication yield were recorded. Four ears were selected 

 at random from each replication for drying down to a uniform moisture 

 content. The uniform moisture basis was used for calculating the mois- 

 ture loss and yield per acre of grain. 



In the 10 years that the grain trials have been conducted, certain 

 Michigan, Minnesota, and Wisconsin hybrids have stood out. Cornell 

 29-3 has given a good account of itself both for grain and silage. Massa- 

 chusetts 62, a new hybrid, gave the best yield of grain for the 1945 sea- 

 son, and stood fourth for silage. 



The 1945 season was a poor corn year and the resulting data are 

 quite unreliable. Due to a cold and wet spring, the planting was late and 

 the stand was not uniform. Furthermore, rodent damage was the worst 

 ever experienced.

Introducing New Potato Varieties for Certified Seed 



During the 1945 season, the Mohawk variety of potatoes was intro- 

 duced and planted as tuber unit stock in the Colebrook area. This varie- 

 ty was chosen because of its excellent cooking quality since it was hoped 

 that it might serve as a replacement for the Green Mountain, a variety 

 which is losing popularity because of its susceptibility to net necrosis.
