Switchgrass biomass yield and composition and soil quality as affected by treated wastewater irrigation in an arid environment

چکیده
Freshwater (FW) scarcity as a result of prolonged drought has reduced FW availability to agriculture in the arid west Texas region order meet demands from other sectors. Alternatively, there is enormous potential utilize treated urban wastewater (TWW) for agricultural irrigation. However, soil salinization TWW concern it can be detrimental crops and quality. Alternative that are both less water-intensive salt-tolerant therefore needed sustain this region's agriculture. Switchgrass perennial grass well adapted grow on marginal lands novel crop lignocellulosic bioenergy feedstock. its performance when irrigated with soils far largely unknown. This field study evaluated yield composition switchgrass biomass affected by along quality changes, using split-plot experimental design. Results indicate yields were not irrigation no significant differences between across years. With respect composition, cellulose lignin contents lower, while ash content was significantly higher treatment. Theoretical ethanol production affected. Soil salinity sodicity increased overtime but increase more prominent under application gypsum sulfur sodicity. These results tolerate induced successfully grown these

Tea yield and soil properties as affected by slope position and aspect in Lahijan area, Iran
Soil genesis, physico-chemical properties and tea yield were investigated along different hillslope positions in the major tea cultivation area of Iran, i.e. Lahijan, Gilan Province. Land suitability was also determined for the tea production in this hilly region. Four different slope positions i.e., summit, shoulder, backslope and toeslope were sampled on three slope aspects following the prof...
متن کاملYield and Qualitative Traits of Sesame as Affected by Irrigation Interval, N Fertilizer and Superabsorbent
In order to study the effect of irrigation interval, N fertilizer and superabsorbent on yield and qualitative traits of sesame (Sesamum indicum L.), a split-split-plot experiment was coducted in a farm in Khusf of Birjand, Iran in 2009 on the basis of a Randomized Complete Block Design. The main plot was devoted to irrigation interval at three levels of 6, 12 and 18 days, the sub-plot was devot...

The effects of soil type, irrigation, and population density of Rotylenchulus reniformis on cotton were evaluated in a two-year microplot experiment. Six soil types, Fuquay sand, Norfolk sandy loam, Portsmouth loamy sand, Muck, Cecil sandy loam, and Cecil sandy clay, were arranged in randomized complete blocks with five replications. Each block had numerous plots previously inoculated with R. r...
