vantage of wider adaptation to land too stony or stumpy for plowing, and, 

 also, it leaves more of the organic layer on the surface which may he of some 

 significance in water absorption . There, has been little or no difference in 

 the appearance or yield of the stand between the two methods of seed bed 

 preparation. 



The seedings included one or more of the following grasses with La- 

 dino clover : orchard grass, smooth brome grass, reed canary grass, tall 

 meadow fescue, perennial rye grass, and two strains of timothy, namely, 

 Milton and Cornell 1777. The areas so seeded were managed as pasture 

 during a part or all of the 1943 season, and all of those areas caged and 

 harvested were pastured all of the season. Since all areas had been ade- 

 quately fertilized and limed in 1942, no lime, superphosphate, or potash 

 were applied in 1943. Several of the pastures were divided crosswise of 

 ithe plots, however, and nitrate of soda was applied at three levels (leaving 

 untreated check strips) to note the influence of nitrogen or yields and its 

 effect on the persistence of the Ladino clover. Two of the pasturas on 

 which nitrogen was applied at different levels were harvested and the re- 

 spective yields noted. The results follow :

In the Angell pasture, the soil is a loam and subject to drought, where- 

 as the Peters pasture is a very heavy soil and perhaps somewhat less af- 

 fected by drought. These facts may explain why greater response was se- 

 cured in the Angell pasture. Ladino clover growth was vigorous on all 

 plots and undoubtedly had considerable effect on the yields of other grasses. 

 The variations in yield per acre among these grasses is not great. It is 

 conceivable that as the Ladino clover disappears greater differences may 

 occur. 



A rate-of-seeding experiment was conducted in one pasture for or- 

 chard grass. One plot each was seeded at the rate of nine, six, and three 

 pounds, and the resulting yields were 6210 pounds, 5548 pounds, and 4908 

 pounds, respectively. Ladino clover was included in all plots at the rate 

 of two pounds per acre. 



The Department of Agricultural and Biological Chemistry, co- 

 operating, has made supplementary observations on these pasture experi- 

 ments. 



The light soil pasture was sampled by levels and there was a steady 

 decline in available nitrates as the season progressed. The plots receiving 

 higher applications of N had the highest level at the start of the season. 



The pasture on the heavier soil had a very good stand of Ladino clover 

 with some red clover. Three levels of nitrogen were applied and half the 

 plots were cross treated with three levels of phosphorus and potash. There 

 was a significant increase in yield in pounds of protein per acre whenever 

 the half of the plot receiving complete fertilizer w'as compared with * the
