Field experiments were conducted in 2006 to investigate the impacts of modified rice cultivation systems on: grain yield, N uptake, ammonia volatilization from rice soil and N use efficiency (ANUE, ag...
Patterns of Soil Nitrogen Release in Paddy Fields of Warm Regions in Japan and Diagnosis of Fertilizer Application : III. Evaluation of amount of soil nitrogen supplied from paddy fields in relation to rice yield
Ammonification Nitrogen uptake Paddy soils Rate of Fertilizer application Soil nitrogen
2009/7/30
It was investigated whether the amount of ammonification could be used as an index of soil analysis for fertilizer application, which was related with the amount of soil nitrogen supplied from paddy f...
Rice Yield by the Culture with Minimal Agricultural Chemicals in the Field with Continuous Application of Farmyard Manure or Chemical Fertilizer(Agronomy)
Continuous application of farmyard manure Culture with minimal agricultural chemicals Fluctuation of yield Koshihikari Panicle blast
2009/7/15
From 1991 to 2000, a rice cultivar, Koshihikari, was grown in the field, where either farmyard manure or chemical fertilizer was continuously applied. A minimal amount of herbicide and pesticide were ...
