l/ The su.li or the years vineyojrds were seeded to cover crops was divided by the 

 sum-, of the years vineyards were studied and the q,uatient was multiplied by 100. 

 In addition to the 308 vineyards shovm in this table for which cover crop data 

 were reported for 5 yeai's, there ?/ere Included 246 other vineyards for v;hich 

 cover crop data were reported for 1 to 4 years. 

 2/ Data for Arkansas are for the year 1929 and for the 5 -year period 1925-1929. 



Kinds Used 



For all vineyards studied, rye alone v/as used as a cover crop on 45 

 percent, and rye mixed with other seeds on 13 percent of the total acreage -seeded 

 (table 25.) Thirteen different kinds of cover crops wore used in the vineyards 

 studied. Next to rye, the most importcnt crops were rape, vetch, and oats. 

 Buckwheat v/as the most important cover ci-op in the Hudson Valley and in the 

 Finger L?akes areas. 



i^ 



Many growers consider rye satisfactory as a co%^or cr'^p. In the spring, 

 rye comgetes with the grapevines for moisture and plant food, and is difficult 

 to subdue if left too long, thorcforo, it shoiad be turned under early. 



The majority of the groi7crs in all cf the areas studied, except Girard, 

 depend upon v/eeds for cover crop;
