“…Better crop growth particularly of leafy vegetable like cauliflower, cabbage, spinach etc. grown on fields receiving sewage WW have been achieved [74], in contrast to radish, which is mo re sensitive to WW [75]. The results of many studies on the use of WW for long period of time have recapitulated significant increased in crop yields than GW irrigated fields.…”

Paucity of quality fresh water for agriculture has made waste water (WW) application a popular option.Available data on chemical co mposition of different waste water, their effect on soil fert ility, soil heavy-metal content, crop yield and quality parameters and maximu m permissible limits (MPL) of different International environ ment protection agencies and governments of different countries has been summarized. Chemical composition of WW varied remarkably with respect to their heavy-metal content, pH, electrical conductivity (EC), biolog ical o xidation demand (BOD), chemical oxidation demand (COD), alkalinity and hardness. Field application of all types of waste water significantly increases soil OC percentage, soil EC, cation exchange capacity (CEC), total and DTPA-ext ractable heavy-meta l/ mic ro-nutrient content, available macro -nutrient (N, P and K) content with significant decreases in calciu m carbonate content of surface soil. However, high content of nitrogen, phosphorus and potassium strengthens its high fertigation/ manural value for field crops. Significantly higher heavy-metal accumu lation in soils irrigated with WW than ground water has been observed in surface layer than the lower depths of soil profile. Since crop genotypes and even crop cultivars within genotypes respond differently to waste water irrigation, their selection becomes mo re important under such situations. More importantly, carbon sequestration through WW irrigation could sustain long-term soil fert ility. Periodic monitoring of chemical composition of waste water, soil and crop produce is however, suggested for safe and long term use of waste water.

To cite this paper: Iqbal, M.M., G. Murtaza, Z.A. Saqib and R. Ahmad, 2015. Growth and physiological responses of two rice varieties to applied lead in saltaffected soils. AbstractIn arid and semi-arid regions of the world, soil salinity and heavy metal pollution occurring through various natural and anthropogenic means, is becoming major threat to safe crop production. The most feasible and effective approach is screening, breeding and cultivation of food crop varieties with low toxic metal accumulation. A pot study was conducted to investigate the growth and physiological responses of rice exposed to applied lead (Pb) in normal and salt-affected soils comprising four levels of Pb (0, 50, 100 and 150 mg kg -1 soil), two rice varieties (Shaheen basmati and KS-282) and two types of soil as normal and salt-affected soils. Increasing level of Pb decreased plant height, straw and paddy yields, photosynthetic and transpiration rates and stomatal conductance, more under salt-affected conditions. The cv. Shaheen basmati showed better response for growth, yield, physiological attributes and had lower Pb concentration in straw and paddy compared to cv. KS-282, at all levels of applied Pb in both normal and salt-affected soils. Thus, Shaheen basmati was found to be grown for Pb risk-free rice production and can be a good source for future rice breeding programs with the aim to produce low Pb accumulation and salt-tolerant rice varieties.

14In order to clarify how cadmium (Cd) chemical forms in planta relate to the genotype difference 15 in Cd accumulation of spinach (Spinacia oleracea L.), two low-Cd and two high-Cd cultivars 16 were compared under a hydroponic experiment with two concentrations of Cd (1 or 5 mg Cd L -1 ). 17The concentrations of phosphorus in the hydroponic system were also adjusted to two levels tested cultivars and the effect had superiority over the cultivar alternation under higher Cd stress. 24Cadmium in the NaCl-extractable fraction of the plant tissues showed the greatest relationship to
