“…Increasing soils pollution caused by heavy metals (HMs), due to agricultural and industrial activities, is becoming a serious environmental problem to the present world (Li et al, 2013;Imran et al, 2015). The direct and indirect discharges of industrial and urban wastes have resulted in the chemical contamination of the soil by organic pollutants and HMs (Sun et al, 2012;Elloumi et al, 2015).…”

The proposal to use sewage sludge (SS) on agricultural fields as a sustainable way to dispose of the waste is based on its high organic and nutrients content. However, the presence of heavy metals (HMs) in sludge can contaminate crops and accumulate in the food chain. The aim of this study was to assess changes in soil fertility, biochemical responses of tomato (Solanum lycopersicum L. cv. Rio Grande) seedlings and the availability of HMs with increased rate application of SS (0, 2.5, 5 and 7.5%). Leaf chlorophyll content, nutritional status, proline, membrane peroxidation, stomatal conductance and HM accumulation were investigated. Results showed that the soil pH decreased, whereas soil salinity, organic carbon, total N, available P and exchangeable Na, Ca, K and HM content increased significantly with increasing application rates of SS. Among the three HMs (Zn, Cu and Cr), Zn had the highest capacity for transferring from soil into plants. Low metal translocation was observed from roots to leaves. The 7.5% SS dose decreased biomass production and caused a decline in chlorophyll content and stomatal conductance. However, lipid peroxidation and proline contents increased. Therefore, the use of 2.5 and 5% doses of sewage sludge in agriculture would be an efficient and costeffective method to restore the fertility of soil and an environment-friendly solution for disposal problems.Additional key words: sewage sludge amendment; soil fertility; biochemical responses; Solanum lycopersicum.

Although the development of organic products have been a decisive factor in rapid development for the last two centuries, hazardous solvents, nonbiodegradable catalysts, and long reaction times have always been a serious issue in organic synthesis. The solution to all issues highlighted above lies in the environment-friendly synthesis and green chemistry. In such synthesis, reaction time is decreased by using energy-efficient methods of heating (like microwave irradiation), high yield, biodegradability, good selectivity of solvents, good performance of catalysts, and usage of environment-friendly greener solvents like water, ethanol, acetone, etc. in an all-in-one approach [1]. Auxins, a class of naturally organic compounds, are plant growth hormones found in and required by plants in very little amounts, yet their presence is very critical. This class of compounds contain acetic acid-based Pol. AbstractPreparing novel compounds using environment-friendly protocols for plant growth has remained a major goal for plant scientists. In this research, effect of a novel plant growth promoter on sunflower (Helianthus annuus L.) was assessed hydroponically as well as in soil acclimatized plantlets at 1, 10, and 100 µM. The plants were also assessed for antioxidant enzymatic and antifungal activities. The synthesized derivative 2 produced significantly better results in terms of overall growth as compared with standards at 1 µM concentration among all compounds. Increased catalase and superoxide dismutase levels in plant seedlings treated with synthesized compounds were observed when grown in hydroponics, but these values were found to be significantly low as compared to soil-acclimatized plants. No significant zone of inhibition was found on agar plates in antifungal bioassay.
