shortage of irrigation water, being a crucial problem in arid and semiarid regions, makes it necessary to use treated wastewater in agriculture. a field experiment was conducted to investigate the effect of treated municipal wastewater (tmw) on the yield and fiber quality of cotton (gossypium hirsutum l.) (mehr variety). treated municipal wastewater was supplied from shahrake ghods sewage treat...

this paper describes a methodology for the integration of well logs and a series of grid-based attributes extracted from interpreted seismic data for prediction of porosity distributions. the studied area is located in the southwest iran. before finding a relationship between the target logs and predicted logs from 3d seismic data, we have interpreted the 3d seismic data in the studied area. al...

nitrogen forms exert significant effects on physiological and morphological characteristics of plant. in this study, the effects of ammonium, nitrate, and ammonium-nitrate on pepper plants were investigated in soil culture, as well as in solution culture. in the soil culture, 3, 4-dimethylpyrazole phosphate (dmpp) was used as a standard nitrification inhibitor to guarantee the presence of ammon...

forest cover is one of the most effective factors in reducing flooding in northern iran, so that in recent years the destruction, land use changing and uncontrolled harvesting of forest areas, has greatly increased the number and magnitude of floods. so far, there have been few studies on forest hydrology in iran, particularly the northern hyrcanian forests. this study examines the impact of a ...

in this research, moisture sorptions of sayer date were determined at 20, 30, 40 and 60°c, using the standard static gravimetric method developed by the european cooperation project cost 90. several mathematical models, namely gab, bet, iglesias & chirif and halsey were employed to fit the experimental data through non-linear regression. results indicate that equilibrium moisture content increa...

the aim of this study was to investigate the barrier properties of cellulose nanocrystals-pvananocomposites. nanocomposite films with different filler loading levels (3, 6, 9 and 12% by wt) weredeveloped by solvent casting method. the effect of cellulose nanocrystals on the barrier properties ofthe nanocomposites was studied. to this end, moisture absorption, water vapor permeability (wvp),oxyg...

low seed germination and seedling emergence is one of the main problems in saline areas. seed priming technique has been known as a challenge to improve germination and seedling emergence under different environmental stress. the objective of this research was to evaluate the effect of seed priming with gibberellin, nacl and water on seed germination and seed reserve utilization and germination...

rice (oryza sativa l.) is one of the iran's most strategic crops with water shortage as the most important abiotic stress limiting its yield. in the present research the effects of: variety, water regime, nitrogen (n) and phosphorus (p) levels on n, p and k uptake were studied under greenhouse conditions. the experiment design was a factorial one based upon a randomized complete blocks of ...

decreasing water loss and increasing the irrigation times are basic methods to develop agriculture, success in natural recourse projects, minimize the stress to planted bushes in natural fields and increase the productivity of soil and water sources. the use of super absorbent is one of these strategies to achieve these goals. the main purpose of this research was to study the effect of super a...
