Dolomitic lime at l^i tons/acre was applied to the site on June 30 and 

 on August 9, 1976. Conventionally seeded plots were plowed July 9, 1976. 

 so that half the lime was plowed down and half disced into the seedbed. 



The field on which this experiment was located (Site No. 1) was seeded 

 10 years prior to red clover and timothy (Table 1). In July, 1976, quackgrass 

 represented 36%, broadleaf weeds 29%, timothy 25% and clovers 10% of the 

 undisturbed sod. On August 3, 1976, 2,4-D was applied to the entire area at 

 one lb. a. e. /acre for control of dandelions and other broadleaf weeds. Sod- 

 seeded plots were mowed four days before seeding and paraquat at one quart/acre 

 with 1% v/v surfactant was applied one day before seeding. All plots were 

 seeded on August 16, 1976, and on May 6, 1977, with a mixture of 12 lbs/acre of 

 'Pennscott' red clover and 6 lbs/acre of 'Climax' timothy. Paraquat at the 

 rate previously used was applied on May 11 to plots sod-seeded in the spring. 



At this site a split block design was used. It was replicated four 

 times with main plots consisting of conventional and sod seedings in August, 1976 

 and May, 1977, and an unseeded sod control. Subplots consisted of rates of 

 5-20-20 (none, 250, 500, and 1,000 lbs/acre). Fertilizer was disced into 

 plowed seedbeds, but left on the surface with sod seedings. Sub-subplots were 

 either untreated or treated on November 8, 1976, with Kerb at 1^^ lbs a. i. /acre. 



Establishment of legume-grass mixtures 



The Hollis-Charlton soil on which this experiment was located (Site No. 2) 

 is considered to be well to excessively drained and droughty, due to low 

 moisture retention (Table 1). It was very rocky and an average three feet to 

 bedrock. The slope was 10-15%. Prior to applying treatments the pH was 5.6 

 and the soil was low in all major nutrients. 



The original sward was totally lacking in legumes or productive grasses. 

 It was dominated by field brome and broadleaf weeds.
