Title
Effect of nitrogen on the growth, yield and grain protein content of barley ( Hordeum vulgare )
CJ Birch; KE Long Australian Journal of Experimental Agriculture 1990. doi:10.1071/ea9900237
Other claims from this paper (10)
- Intervention effect Nitrogen delayed maturity in all barley cultivars, especially Galleon.
- Intervention effect Nitrogen increased total and fertile tiller numbers, with a significant cultivar by rate interaction.
- Intervention effect Increasing nitrogen reduced fertile tiller percentage.
- Intervention effect Grain protein content increased with nitrogen rate, with linear response in Corvette and quadratic response in the other two cultivars.
- Observation Total and fertile tillers peaked at 150 kg N/ha except fertile tillers in Grimmett at 100 kg N/ha.
- Association Dry matter and grain yields responded quadratically to nitrogen in Grimmett and Galleon, with predicted maxima near 200 kg N/ha.
- Association Corvette dry matter and grain yields responded linearly to nitrogen over the tested range.
- Recommendation Breeding programs should select barley for efficiency of nitrogen use while considering variation in yield and protein response.
- Recommendation Recommended nitrogen rates for irrigated barley are 150-200 kg N/ha.
- Association Lower nitrogen rates promote strong yield responses but leave protein content low.
