this study was performed to investigate the photosynthetic partitioning pattern of materials to aerial parts of bread wheat in dryland conditions. it was as well to study its relationship with bread wheat resistance and grain yield in drought conditions. seven genotypes including two cultivars (azar2, sardari) and five lines were investigated in a field experiment through a randomized complete ...

This study aimed to identify chemical composition of Thymus kotschyanus essential oil (TKEO) and to evaluate the effects of different doses of TKEO on in vitro gas production, fermentation parameters, acidosis and protozoal population using a completely randomized design with four replicates. Two diets (D1: 100% forage and D2: 30% forage+70% concentrate) were incubated with buffered rumen fluid...

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...

Background: Drought is a leading abiotic factor limiting groundnut production globally. Therefore, the screening and development of moisture stress tolerant genotypes key issue towards sustainable agriculture. Methods: An experiment was laid in split plot design taking two conditions, control (T1) (T2) as main treatments 7 sub treatments. Several morpho-physiological traits like dry matter prod...

The objectives of this work were to determine the effect of nodulation on dry matter, reduced-N, and phosphorus accumulation and partitioning in above-ground vegetative parts and pods of field-grown soybean (Glycine max [L.] Merr. cv Harosoy).From comparison of nodulated and nonnodulated isolines, it was estimated that nodulated plants attained 81 and 71% of total-plant (above ground) N from up...
