abstract             the aim of this study was to evaluate the effect of ajowan essential oils (aeo) on rumen fermentation using in vitro gas production. therefore, different doses of aeo (i.e., 0, 150, 300, 450 or 600 ppm) were added to the syringes of the gas production. a typical diet of growing lambs was used as fermentation substrate.  at the first step, the gas production syringes were in...

The experiment was conducted to investigate potential causes of grain sterility in widely cultivated rice variety in Malaysia, MR219 and its two mutant lines (RM311 and RM109) by examining the source-sink relations. RM311 produced increased dry matter yield both at heading and maturity and also showed higher grain yield with greater proportion of grain sterility than the other two genotypes (RM...

in order to evaluate different sources and rates of nitrogen on dry matter yield, concentration and uptake of primary macronutrients (nitrogen, phosphorous and potassium) in forage sorghum (hybrid of speedfeed), three levels of nitrogen (80, 160 and 240 kg n ha-1) from three n sources (urea fertilizer, cattle manure and equal combination of urea fertilizer + cattle manure) and the control (no f...

this study was conducted to investigate the effects of different doses of salvia mirzayanii essential oils on gas production parameters, fermentation characteristics using gas production and dual flow continuous culture system. trearments in the gas production experiment was adding 0, 400, 800, 1200, 1600, 2000, 2400 and 4800 mg/l of salvia mirzayanii essential oils to the media. in the second ...

The economy of C and N in nodulated cowpea (Vigna unguiculata [L.] Walp.) was described in terms of fixation of CO(2) and N(2), respiratory losses of C, and the production of dry matter and protein.Net daytime gain of C by the shoot (net photosynthesis) rose to a maximum at flowering and then declined sharply due to abscission of leaves. Maximum N fixation occurred 10 days prior to maximum net ...

five species of dominant halophyte plants including: salsola griffithii, chenopodium album, aeluropus logopoidies, alopecurus textillis and cardaria draba were sampled from sistan region at their late vegetative stage. the collected samples were dried at room temperature and ground, and their chemical components including: dry matter, organic matter, ash, crude protein, crude fat, as well as ce...

Carbon isotope discrimination (CID) has been proposed in estimating transpiration efficiency (TE) in plants indirectly To identify variations for TE and specific leaf area (SLA) and their association with CID, a glasshouse experiment was conducted using six prominent species of Cenchrus. A significant increase in TE (3.50 to 3.87 g kg(-1)) and decrease in SLA (219.50 to 207.99 cm2 g(-1)) and CI...
