to predict growth and yield, it is needed to study sub-models of phenology, dry matter production and partitioning, leaf area and soil water balance. in the present study, for predicting yield of faba bean under gorgan conditions, parameters of sub-models were estimated using data of planting dates in gorgan and data of other researchers in different regions of world. daily variations of phenol...

Low light responses of eight garden pea genotypes were investigated in the present experiment in terms of dry matter accumulation and partitioning in the plant. The light treatments consisted of (i) 100% photosynthetically active radiation (PAR) measured in the open field and (ii) 25%, (iii) 50%, (iv) 75% reduction of natural PAR obtained by using mosquito nets of variable color and mesh number...

This experiment was conducted to study the effects of various amounts of treated sunflower meal (SFM) with extracted tannins from pistachio hulls on in vitro gas production and ruminal fermentation in ruminants. The SFM was treated with pistachio extract concentrate (PEC), which contained 111.40 g kg-1 total phenol and 71.30 g kg-1 total tannin per dry matter of extract, at six experimental tre...

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...

The aim of this research was to study the in vitro effect of Lavandula officinalis (LEO) and Origanum vulgare (OEO) essential oils on rumen fermentation using a concentrate type substrate (CTS) and roughage type substrate (RTS). Six Mehraban ewes were divided into 2 groups and fed a concentrate type or roughage type diet, and used as rumen fluid donors. Each essential oil (EO) was evaluated sep...
