Phytoremediation potential of L. minor for cadmium (Cd), copper (Cu), lead (Pb), and nickel (Ni) from two different types effluent in raw form was evaluated a glass house experiment using hydroponic studies period 31 days. Heavy metals concentration water plant sample analyzed at 3, 10, 17, 24, day. Removal efficiency, metal uptake bio-concentration factor were also calculated. Effluents initially physical, chemical microbiological parameters results indicated that municipal (ME) highly...

Among the major nutrients, potassium (K) not only improves yields but also quality parameters. Field experiments were conducted to assess comparative effect of sources and rates K fertilizer on potato yield a sandy loam soil. Graded doses potassium, i.e., 0, 150 225 kg ha−1 K2O from sulfate muriate potash applied in triplicate. Recommended dose nitrogen (N) phosphorus (P) uniformly. Significant increase tuber was observed with both over control. Increase statistically non significant...

Contamination of pre-urban arable land, by untreated municipal/industrial effluents derived heavy metals, is causing serious health hazards to human beings and abiotic components the ecosystem. In this study, phytoremedial potential four non-eatable floriculture plants, i.e. antirrhinum, pansy, calendula, marigold, was explored growing in metal contaminated soil (collected from area under wastewater irrigation for more than 20 years) amended with bacterial inoculum EDTA soils greenhouse...

We studied the diet of Indian flying fox (Pteropus giganteus) in Pakistan from March 2008 to February 2009 and found that bats fed on 20 species belonging 11 plant families. Of these, four families (Anacardiaceae, Bignonaceae, Malvaceae, Sapotaceae) were identified remnants flower petals food boluses while remaining (Annonaceae, Arecaceae, Ebenaceae, Meliaceae, Moraceae, Myrtaceae, Sapindaceae) seeds guano samples. Plants family Moraceae (50.7%) comprised most bat's diet. Fruit Ficus retusa...

A five-year cotton–wheat rotation field experiment was conducted on two alkaline-calcareous soils, i.e., Awagat (coarse loamy) and Shahpur (fine silty), to investigate the impact of integrated nutrient crop residue management soil productivity. Apparent nitrogen (N) balances were developed. Minimum mean yield (Mg ha−1), obtained with Farmers' Fertilizer Use (FFU) treatment was: cotton – Awagat, 2.19; Shahpur, 2.45; wheat 3.03; 3.94. With Balance Nutrient Management (BNM), yields increased (P...

A 5-year cotton–wheat rotation field experiment was conducted on two alkaline-calcareous soils to investigate the impact of integrated nutrient-management and crop-residue incorporation soil physical hydrological properties. The nutrient treatments were: T1–farmers' fertilizer use; T2–balanced management (recommended N, P, Zn. B from mineral sources); T3–integrated management, same as T2, except that 75% N applied 25% FYM; T4 every alternate year, wheat substituted by Berseem green manure....

Abstract Laboratory batch and greenhouse pot experiments were conducted to determine the extraction efficiency of ethylenediaminetetraacetic acid (EDTA) for solubilizing lead (Pb) cadmium (Cd) explore natural chemically induced Pb Cd phytoextraction efficiencies spinach mustard after EDTA application. The was applied at 0, 1.25, 2.5, 5.0 mM kg−1 soil in three replicates. Addition increased significantly soluble fraction over control maximum increases (1.42- 1.96-fold) (1.45- 1.38-fold)...

Hexachlorocyclohexane (HCH), a highly chlorinated pesticide, was used worldwide in the 1950s and 1960s. HCH toxic residues are still detected environmental compartments. Thus, effective, viable eco-friendly strategy is required for its remediation. In this study, degradation of four isomers evaluated by amending contaminated soil using treatments spent mushroom compost (SMC) Pleurotus ostraetus. The incubated 5 weeks sampled every seven days. Quantitative attenuation calculated gas...

Heavy metals phytoextraction potential of swollen duckweed (Lemna gibba Linn.) and lesser aequinoctialis Welw.) was determined under greenhouse conditions by exposing to untreated industrial/municipal effluent for a period 21 days. The nickel (Ni), lead (Pb), cadmium (Cd) concentrations in water samples were measured weekly plant biomass at the termination experiments. Significant differences (p < 0.05) between initial final physicochemical parameters heavy metal observed. Periodically...

Roost characteristics of Indian flying fox Pteropus giganteus at the Jinnah (n = 1052) and Lalazar 40) gardens in Lahore were observed for a period 1 year to find roost preferences these bats. The garden harbors 4119 trees belonging 46 families, 103 genera, 132 species, which 44 17 19 21 species served as bat roosts. 90 representing 7 9 species. Six 2 each Height roosting varied from 7.5 m (Dendrocalamus hamiltonii) 19.8 (Celtis australis) diameter breast height (dbh) ranged 0.10 (Putranjiva...

This study aims to examine the heavy metal phytofiltration potential of Hydrocotyle umbellata from Nullah Lai wastewater and its environmental risk. Wastewater was initially analyzed for metals physicochemical parameters compared with irrigation water standards. The H. determined by periodically monitoring concentrations at time points T1 (day 05), T2 (day10), T3 15), T4 20). shows that some reached permissible limits after treatment umbellata. Results risk analysis reveal a significant...
