Other claims from this paper (10)
- Observation Wheat crown roots, tillers, forage yield, root weight and grain yield were higher at Scottsbluff than Sidney.
- Intervention effect Wheat growth and yield measures did not differ among treatments at either site.
- Intervention effect Wheat root acetylene reduction rates were very low and showed no significant treatment differences.
- Observation Sorghum nitrogenase activity differed significantly across experimental factors.
- Intervention effect Nitrogen reduced nitrogenase activity in all three sorghum cultivars.
- Intervention effect Phosphorus increased nitrogenase activity in sorghum cultivar CK60B.
- Intervention effect Bacterial inoculation did not increase sorghum forage or grain yield or nitrogen content.
- Observation Sorghum cultivar CK60A had the highest yield and nitrogen content.
- Association Bacterial inoculation increased sorghum yield through its interaction with fertilizer.
- Observation Sorghum cultivars R-8193 and CK60B had the most root nitrogenase activity among twelve cultivars.
