partitioning of photoassimilates between the sinks is one of the most important physiological processes related to the yield of crops which are affected by drought stress. therefore, the effect of drought stress in flowering and grain filling stages, on the percentage partitioning of photoassimilates among different organs was studied in 14 rapeseed cultivars in a split plot experiment based on...

of these differences may be attributed to climatic factors (Is). However, within seasons between adjacent fields, different sucrose concentrations have been measured. Some of these differences may be attributed to variations in early plant growth and N uptake by the sugarbeet plant (16). The objective of this study was to evaluate the effect of several rates and times of N fertilizer applicatio...

A model SUBEMOpo, to simulate sugar beet growth and sugar accumulation for potential production conditions has been evaluated. Given initial conditions, the growth, development and sugar accumulation of the model are driven by observed weather (i.e. maximum and minimum temperatures, rainfall, wind speed, relative humidity and solar radiation). Soil water and nutrients are considered as non limi...

in this experiment, different doses of zataria multiflora (zm) and eucalyptus globolus (eg) essential oils (eos) (0, 100, 250, 500, 750 and 1000 µg/ml) and a mixture of them were added to alfalfa hay incubated with buffered rumen liquor of merghoz goat to assess in vitro gas production, rumen fermentation and protozoa population. in all treatments the asymptotic gas volume (b) and the rate cons...
