Other claims from this paper (7)
- Intervention effect Production of vetch and barley was lower in monocultures than when grown in rotation.
- Observation Vetch yield was similar in all rotations, irrespective of the position in the cycle.
- Intervention effect Barley productivity was increased by nitrogen application only when barley was grown as a second crop after vetch.
- Intervention effect In years with low productivity due to rainfall, barley did not respond to nitrogen application.
- Intervention effect Nitrogen fertilizer had a decreasing effect on the size and weight of barley grains.
- Recommendation The results allow farmers to select any of the rotation systems studied, based on economics, without risking productivity.
- Recommendation Nitrogen fertilizer should be applied only to the second crop after vetch in years with high rainfall.
