In order to increase the available Phosphorous (P), chemical fertilizers are applied; however, P chemical fertilizers are transformed into low available forms over time. Organic amendments could be effective in improving the efficiency of P fertilizers. The aim of this study was to investigate the effect of P fertilizers and vermicopost on the availability and fractions of P and maize (Zea Mays...

Extended Abstract Introduction and Objective: To overcome the problems caused by animal feed shortages, efforts are made to increase the availability of nutrients and their digestibility, such as improving the nutritional value of forage plants through biological processing. Schizophyllum commune is an edible fungus of the basidiomycete’s family that has been used for biological processing of ...

Understanding variation in SW (seed weigh) is of major importance in understanding SY (seed yield) variation. The objective of this study was to determine factors such as SN (seed number) per unit area, SFD (seed filling duration) and SFR (seed filling rate) and temperature, LAI (leaf area index), LAD (leaf area duration), above-ground dry matter, CGR (crop growth rate), leaf dry matter re...

To evaluate forage production and land equivalent ratio (LER) in additive and replacement intercropping systems of forage sorghum and berseem clover, a field experiment was conducted using randomized complete block design with eight treatments and three replications at the research field station of Seed and Plant Improvement Institute, Karaj, Iran, in 2016-17 and 2017-18 growing seasons. The ex...

Dear Sir,?I read with some concern the notes of K. R. regarding my reference on choline content of milk published in the February 1951 issue of the Gazette. The edible portion of dry skim milk, dry whole milk and fresh milk being common in all the three varieties, how could the choline content in the first two vary by dilution ? It is of course true that a given quantity of dry skim or dry whol...

a simple mechanistic model was constructed to evaluate potential dry matter of pearl millet. all needed parameters were calculated based on many field and laboratory experiments and actual data obtained from 86 fields of millet located at different regions of khorasan's provinces. the major simulated processes were crop phenology (as a function of temperature and photoperiod function curve...

In order to investigate the effect of vermicompost and Nano Iron on yield and yield components of maize, a farm experiment was done in a factorial based on completely randomized blocks design with three repetitions in Damavand in 2013. The first factor was vermicompost in two levels included no applying and applying (vermicompost 1kg.m-2) and the second factor was Nano iron fertilizer with four...

stem reserves of barely can be an important contributor to grain filling particularly under condition is limited such as salinity stress. the aim of this research was to study dry matter accumulation and remobilization ability in different internodes of some iranian barley varieties and promising lines under salinity and normal conditions. the research was set up as two randomized complete bloc...

Growth indices are useful for interpreting plant reaction to environmental factor. Using Growing Degree Days (GDD) for estimating the phonological growth stages is more valid instead of calendar time. In order to study effect of salinity on growth analysis in three different plantago species, a greenhouse experiment was conducted in Vali-e-Asr University of Rafsanjan in 2009. The study was carr...
