Winter Cover Crop Seeding Rate and Variety Affects during Eight Years of Organic Vegetables: I. Cover Crop Biomass Production

Agronomy Journal, 2012
Long‐term research on cover crops (CC) is needed to design optimal rotations. Winter CC shoot dry matter (DM) of rye (Secale cerealeL.), legume–rye, and mustard was determined in December to February or March during the first 8 yr of the Salinas Organic Cropping Systems trial focused on high‐value crops in Salinas, CA.

Winter Cover Crop Seeding Rate and Variety Effects during Eight Years of Organic Vegetables: III. Cover Crop Residue Quality and Nitrogen Mineralization

Agronomy Journal, 2013
Winter cover crops (CCs) can improve nutrient‐use efficiency in tillage‐intensive cropping systems. Shoot residue quality and soil mineral N following incorporation of rye (Secale cereale L.), legume–rye, and mustard CCs was determined in December to February or March during the first 8 yr of the Salinas Organic Cropping Systems trial in Salinas, CA ...

Effects of Seeding Rate and Poultry Litter on Weed Suppression from a Rolled Cereal Rye Cover Crop

Weed Science, 2011
Growing enough cover crop biomass to adequately suppress weeds is one of the primary challenges in reduced-tillage systems that rely on mulch-based weed suppression. We investigated two approaches to increasing cereal rye biomass for improved weed suppression: (1) increasing soil fertility and (2) increasing cereal rye seeding rate.

Seeding Rate and Kill Date Effects on Hairy Vetch‐Cereal Rye Cover Crop Mixtures for Corn Production

Agronomy Journal, 1994
AbstractHairy vetch (Vicia villosa Roth) fixes N for corn (Zea mays L.) production, and cereal rye (Secale cereale L.) accumulates soil N to reduce potential N losses. The objective of this research was to identify optimum seeding rates of vetch‐rye cover crop mixtures at Coastal Plain and Piedmont locations in Maryland. Mixtures evaluated were 14, 21,

Seeding Rate and Planting Arrangement Effects on Growth and Weed Suppression of a Legume‐Oat Cover Crop for Organic Vegetable Systems

Agronomy Journal, 2009
Winter cover crops can add soil organic matter, improve nutrient cycling, and suppress weeds in organic vegetable systems. A 2‐yr study was conducted on organic farms in Salinas and Hollister, CA, to evaluate the effect of seeding rate (SR) and planting arrangement on cover crop density, ground cover, and cover crop and weed dry matter (DM) with a ...

Is the U.S. cover crop seed industry ready to support projected adoption rates? A snapshot of the industry

"In recent years, interest in adoption of cover crops on U.S. farmland has surged in the public and private sectors, as well as with farmers. Cover crops are crops planted to cover the soil and reach different climate and soil health benefits, such as reducing erosion; increasing water availability; and providing weed, pest or disease control; and to ...
