“…In few of the analyses, the quantity of bacteria was significantly positively correlated with FDA (r=0.982, P<0.05), along with the quantity of fungi and actinomycetes, which was significantly positively related to FDA (r=0.985, r=0.975, P<0.01). These positive correlations were observed through biochemical processes [37]. In addition, this result showed that increasing the total quantity of microorganisms increased the FDA activity of the soil [38].…”

Field experiments are described involving nitrogen fertilizer in the wheat field to analyze its effect on microbial quantity and enzyme activity. The results showed that 250 kg N hm -2 applied in the wheat field (1) can increase bacteria, fungi and the quantity of actinomycetes by 39.9%, 56.7% and 70.5% compared to 0 kg N hm -2 . (2) Similarly, the activities of soil urease, catalase and FDA exhibited 60.8%, 18.3% and 49.1% improved variation compared to 0 kg N hm -2 , respectively. (3) Moreover, Shannon-Wiener diversity index (H) and Evenness index (E) reached the peak (H=0.37, E=0.33). Correlation analysis of microbial quantity with enzyme activity indicated that they were related to each other. These findings suggested that soil microbial quantity and enzyme activity were significantly influenced by nitrogen fertilizer and the application of 250 kg N hm -2 in the wheat field was observed to be the best.

“…Nagaz et al (2013) indicated that shoot lost its fresh weight rapidly in water stress situation. On the other hand, the corn plants irrigated with PRD had greater fresh weight in comparison with traditional irrigation system (Li et al 2010); nevertheless, it was not significant at 5% probability level.…”

Purpose Declining water resources, increasing drought period and increasing irrigated area cause a shift to deficit irrigated production which is not based on full water requirement. This study was conducted to investigate the impacts of two different deficit irrigation methods, including traditional deficit irrigation (TDI) and partial root-zone drying (PRD) on water use efficiency (WUE) in corn cultivations located at the lands close to the Shahrekord wastewater treatment plant. Methods A factorial design was employed, consisted of fifteen treatments and three replications. The first factor was three water applications, including 60, 80 and 100 (control) percent of plant water requirement. The second factor was three water sources, including 100% fresh water (FW), 50% water and 50% wastewater (5050), 100% wastewater (WW). T-Tape irrigation type system was used for irrigation of corn (Zea mays L.). The third factor was water management in three levels: full irrigation (FI), PRD and TDI. Results The result showed that dry and fresh weight, leaf area index (LAI), dry biomass percentage and WUE were affected by water requirement at 5% probability level expect of height plant that is affected at 1% probability level. Water quality was affected on all the study indicators of corn plant expect of WUE. WUE among PRD by deficit irrigation treatments were higher than TDI and it was the minimum in FI. The dry and wet weight and LAI were maximum at FI and then PDR 80 than TDI 80 . The height of corn plants were high at FI and TDI 80 than PRD 80 . Conclusion Finally, wastewater application in treatment named 5050-PRD 80 and 5050-TDI 80 compensated water deficit in WUE, LAI and dry biomass percentage. PRD method recognized more suitable than TDI for corn plants.

“…The negative relationship between WC and invertase activity indicated that the higher soil invertase activity in the upper soil layer in January may have been due to the low amount of precipitation. Invertase catalyzes the hydrolysis of disaccharides to monosaccharides, which are soluble soil carbohydrates that are strongly affected by the soil water content (Chendrayan et al, 1980;Li et al, 2010). The lower rainfall in the winter may have caused the soil to retain more of the soluble carbohydrates that were produced by the litter on the forest floor and thus increased the invertase activity in the upper soil.…”
