Other claims from this paper (8)
- Association With 108 and 267 kg N x hm(-2), grain fill duration, theoretical maximum grain yield and average filling rate decreased as the S application rate increased.
- Intervention effect With 97.5 and 202.5 kg S x hm(-2), N application improved grain filling parameter values.
- Association With 187.5 kg N x hm(-2) or 150 kg S x hm(-2), the parameters first increased, reached a maximum and then decreased as the S or N input increased.
- Observation Grain filling rate increased for 25 days following anthesis.
- Observation After the initial phase, grain filling rate declined at a rate that varied among treatments.
- Association When N input exceeded 187.5 kg x hm(-2) or S input exceeded 150 kg x hm(-2), grain filling rate decreased as S or N input increased.
- Intervention effect Combined N and S fertilizer application at appropriate rates could increase head density and grain yield.
- Intervention effect Regression equations estimated highest grain yield (3753 kg x hm(-2) or more) with a high N rate combined with a moderate S rate.
