The effect of soil salinity on plant growth is due to two factors, namely, increase in osmotic pressure of soil solution and the ionic composition of salt. The present experiment was conducted to obtain information about the response of pistachio (Pistacia vera L.) to salinity and ionic composition of the salt. Salinity with different relative composition of sodium chloride and sodium sulfate w...
Black gram plants subjected to varying levels of Zn supply (0.01 to 10 microM Zn) showed optimum growth and dry matter yield in plants receiving 1 microM Zn. The dry matter yield of plants decreased in plants receiving 0.01 and 0.1 microM Zn (deficient) and excess levels of Zn (2 and 10 microM Zn). The plants grown with Zn deficient supply showed delayed flowering, premature bud abscission, red...
study the effects of inoculation with two arbuscular mycorrhizal (am) fungi, gm (glomus mosseae t.h. nicolson & gerd.)gerd & trappe) and gi (glomus intraradices n.c. schenck & g.s. sm.) on the herb yield, essential oil (eo) content and nutrient acquisition of basil (ocimum basilicum l.) under drought stress conditions,the experiment conducted with 9 treatments and 4 replications. drought stre...
The objectives of this research were to study the varieties and relationships of yield and quality traits under two harvesting management procedures concerning forage dry matter (DM yield) and 5 quality traits such as Dry Matter Digestibility (DMD%), Water Soluble Carbohydrates (WSC%), Crude Protein (CP%), Acid Detergent Fibre (ADF%) and total ash in tall wheatgrass (Agropyron elongatum). In th...
This research was designed and implemented to determine the effect of different irrigation regimes on the grain yield, dry matter, tiller number per unit area, degree of maturity, panicle harvest index, percentage of leaf rolling, day to 50% flowering, and the physiological maturity of rice genotypes, using a split plot randomized complete block design in two years (2014 and 2015). Four irrigat...
To study drought stress effect on grain quality properties of wheat, an experiment was conductedusing 169 recombinant inbreed lines (RILS) under water stress and non-stress condition and with two separated lattice designs. Grain yield, protein yield, protein content, volume of Zeleny sediment, grain hardness, water absorption, grain moisture content and grain dry matter were evaluated. Analysis...
twenty four primiparous and multiparous holstein cows on early lactation, beginning five weeks postpartum, were used for four weeks to investigate the effects of supplemention of rumen-protected choline (rpc) or vitamin e on milk yield, milk composition, dry matter intake, body condition score and body weight. the cows were randomly assigned to one of the following treatments: i)no supplement (...
Yield and nutritive value of sainfoin (Onobrychis vicifolia Scop.) populations in different cuttings
Sainfoin (Onobrychis vicifolia Scop.) is one of the most important forage legumes cultivated as high quality forage. Fifty three species have been identified in this genus in Iran. A field experiment was conducted using randomized complete block design to compare yield and forage quality of 20 populations of sainfoin in Isfahan Agricultural and Natural Resources Center, Iran during 2013 – 2014....
in order to investigate the possibility of planting grass pea and common vetch crops after harvesting wheat and to evaluate the effects of green manure of these crops on yield of potato-wheat in croprotation cycle, this research was carried out using a randomized complete block design with four replications during 2006-2010 at khair-abad research station, zanjan, iran. the treatments were eith...
