nitrogen (n) affects adversely the tobacco yield quantity and quality as it increases yield, chlorine and nicotine contents, but decrease potassium content. this experiment was aimed at optimization of (the balance between) n concentration in leaf, stem and root to increase both yield quantity and quality (high potassium, low chlorine and medium nicotine contents) using artificial neural networ...

There are complex inter- and intra-relations between regressors (independent variables) andyield quantity (W) and quality (Q) in tobacco. For instance, nitrogen (N) increases W butdecreases Q; starch harms Q but soluble sugars promote it. The balance between (optimizationof) regressors is needed for simultaneous increase in W and Q components [higher potassium(K), medium nicotine and lower chlo...

The effects of night temperature on plant morphology and nitrogen accumulation were examined in rice (Oryza sativa L.) during vegetative growth. The results showed that the shoot biomass of the plants was greater at 27°C (high nighttime temperature, HNT) than at 22°C (CK). However, the increase in both shoot and root biomasses was not significant under 10 mg N/L. The shoot nitrogen concentratio...

BACKGROUNDS AND AIMS Leaf functional traits have been used as a basis to categoize plants across a range of resource-use specialization, from those that conserve available resources to those that exploit them. However, the extent to which the leaf functional traits used to define the resource-use strategies are related to root traits and are good indicators of the ability of the roots to take u...
