Field experiments were conducted in 1983 and 1984 to

compare conventional tillage (CT) versus no-tillage (NT)

production of broccoli and cabbage. The tillage treatments

were applied in combination with four rates of applied nitrogen

fertilizer and three cover crops: hairy vetch (Vigia

villosa Roth), Austrian winter pea (Fisum arvenu L.), and

cereal rye (Secale cereale L.). Transplants of 'Premium

Crop' broccoli (Brassica oleracea var. italica Plenck) and

'Market Prize' cabbage (Brassica oleracea var. capitata L.)

were set with a locally adapted NT vegetable planter. None

of the variables studied affected the final plant stand.

Yield and head size with NT were equal to or greater than

CT. Soil moisture was higher under NT plots throughout the

growing season. Yield and head size with the two legume

covers were equal to or greater than those with the rye cover.

Yield and head size tended to increase as applied N was

increased, although differences were not always significant.

The data, although not conclusive, indicate that the legume

cover crops provided additional nitrogen for the cole crops.
