Abstract The critical nitrogen (N) dilution curve, which expresses whole-plant N concentration as a function of shoot biomass, can be used management diagnostic tool for cereals. objectives this research were to develop curve wheat grown in calcareous soils and formulate model estimating fertilizer requirement crop at different growth stages. Six fertilization rates (0–250 kg ha −1 ) induce var...

The experiment was conducted to assess the effects of maternal nutrition in late gestation on glycogen pools of newborn piglets of different birth weights and to assess how rapidly the glycogen pools in the liver and 3 muscles are mobilized during fasting. Until d 108 of gestation, 48 sows were fed a gestation standard diet (GSD) with low dietary fiber (DF, 17.1%), or 1 of 3 diets with high DF ...
