Title
Cover Crop and Tillage Effects on Production and Nitrogen Nutrition of Sweet Corn
Gary R. Cline; Anthony F. Silvernail HortScience 1996. doi:10.21273/hortsci.31.4.669d
Other claims from this paper (6)
- Intervention effect Tillage had no significant effect on sweet corn yields.
- Observation Where corn received no inorganic N, vetch cover crops produced total N yields of 130 kg/ha, over three times greater than rye.
- Intervention effect Following rye cover crops, ammonium nitrate addition to corn significantly increased corn yields and foliar N concentrations compared with no N.
- Intervention effect Following vetch, corn yields and foliar N concentrations without N fertilization equaled those with N fertilization following rye or vetch.
- Observation Available soil N was significantly greater following vetch than rye for about 9 weeks after corn planting.
- Recommendation The authors conclude that no-tillage sweet corn was successful and that N fixed by vetch was able to sustain sweet corn production.
