Other claims from this paper (13)
- Intervention effect Yield components were significantly increased with enhancing the level of nitrogen.
- Intervention effect Yield components did not differ significantly between 240 and 360 kg N ha-1.
- Intervention effect No N application at tillering stage decreased spikes number per m2 and seeds per spike.
- Intervention effect Removing N application in the grain filling period gave the minimum 1000 grain weight.
- Intervention effect Leaf protein was not influenced by N treatments.
- Intervention effect The sharpness of a band of about 51 kDa, related to Rubisco enzyme, was increased in some N treatments.
- Intervention effect The 240 kg N ha-1 application in all timing treatments gave the maximum seed protein content.
- Observation Seed water soluble proteins, albumin and globulin, showed no polymorphism in wheat seed.
- Intervention effect Different N rate treatments had no significant effect on seed gluten content.
- Intervention effect No N application in the grain filling period significantly declined seed gluten content.
- Recommendation Sufficient N application during vegetative growth is recommended for yield in wheat.
- Recommendation Late season N application is recommended for protein quality in wheat.
- Recommendation High wheat grain yield with suitable bakery quality is possible in a proper farming system without environmental impact of N over application.
