Effects of Previous Tillage System and Nitrogen Rates on Yield and Nitrogen Concentration and Recovery by Turnip

Year: 1986

Type: article

Abstract: Foliage dry weight for a fall turnip ( Brassica rapa L. Rapifera group) crop grown in plowed no-till (NT) plots that previously contained a cover crop of hairy vetch ( Vicia villosa Roth.) (NT + V) was greater for plants grown in plots that were previously treated with N at 0 and 56 kg·ha −1 than with 112 kg·ha −1 . There were significant linear effects of N rates on fresh root and dry foliage weights of turnip plants in plots that had not contained vetch (NT − V), but not for plants in NT + V plots. About 64 and 48 kg·ha −1 of N were recovered by turnip plants grown in NT + V plots that were previously treated with N at 0 and 56 kg·ha −1 , respectively. The previous tillage treatments had no effect on turnip root yield.
