The maximum uptake of Cd 2+ (1.445 mg/g), Ni 2+ (1.585 mg/g) and Cr 6+ (1.594 mg/g) was observed when used 2.0g of GMP biomass, 25 mgL-1 of initial Cd 2+ , 50 mg/l of initial Ni 2+ and 50 mg/l of initial Cr +6 concentration at pH 5, 6 and 3 and contact time of 90, 60 and 90 min at room temperature for Cd 2+ , Ni 2+ and Cr 6+ respectively. The experimental data were analyzed by the Langmuir, Freundlich, Temkin and Dubinin-Radushkevich (D-R) isotherm models. The monolayer adsorption capacity Of GMP was found to be 21.56 mg/g, 53.76 mg/g and 18.87 mg/g for Cd 2+ , Ni 2+ and Cr 6+ ions, respectively. The kinetics of the adsorption was tested using pseudofirst-order, pseudo-second-order, Elovich and intra-particle diffusion models. The results showed that the adsorption of Cd 2+ , Ni 2+ and Cr 6+ ions onto GMP proceeds according to the pseudo-second-order model.

Heavy metals (of Cr, Fe, Mn, Ni, Pb, and Zn) Concentrations (mg/Kg) were determined using atomic absorption spectrophotometry (AAS Model: 210VGP). Plants growth and biomass production were assessed. Biological concentration factors (BCF) and translocation factors (TF) were calculated. The mean levels of elements obtained ranged widely from 0.55 mg/Kg Ni to 1830.64 mg/Kg Fe. The results showed that onion accumulated higher concentrations of all the heavy metals compared to garlic with exception of Zn. However, the differences in heavy metal concentrations where significant only in Cr and Mn. Phytoremediation efficiency indices (BCF and TF) showed a similar trend for both onion and garlic. The mean BCF values of Pb, Cr, Zn, Mn a...

The experiment was laid out in a randomized complete block design with three replications. Thirteen quantitative morphological traits were measured using standard methods. Estimates of phenotypic and genotypic coefficients of variation, broad-sense heritability, genetic advance, correlations, and cluster analysis were performed on the quantitatively measured morphological traits. Moderate GCVs and PCVs were experienced in traits like plant height, peduncle length, stem girth and the number of leaves per plant, showing the presence of moderate variability among the studied accessions for selection. Hierarchical cluster analysis revealed that there is a relationship among the studied Glycine max accessions. Two-main clusters of TGm 275, and 14 other accessions were identified. Four accessions from Kashere clustered together. The closeness observed between KSH005 and TGm607, TGm767 and TGm1005 which wer...

These two are major consideration in cucumber production in the study area. Thus, Field trials were conducted in 2014 rainy season in Teaching and Research Farm, Faculty of Agriculture, Bayero University Kano (11058’N, 8026’E and 475m above sea level) and Kano Institute of Horticulture Bagaud Kano (Latitude 11033'N and Longitude 8023'E) to evaluate the effect of variety and weed control method on weed growth and yield of cucumber (Cucumis sativa L.) Treatments consisted two cucumber varieties (Ashley and Marketmore), and twelve (12) weed control methods (Pendimethalin at 1.5 kg a.i. ha-1, Pendimethalin at 1.0 a.i. kg ha-1, Pendimethalin at 1.0 kg a.i. ha-1 followed by Fluazifop-P-butyl at 1.0 kg a.i. ha-1, Pendimethalin at 1.5 kg a.i. ha-1 followed ha-1 by Fluazifop-P-butyl at1.5 kg a.i ha-1, Pendimethalin at 1.5 kg a.i. ha-1 followed by supplementary hoe weeding (SHW), Pendimethalin...

The overall objective of the study is to compare the effects of organic fertilizers (cow dung and chicken droppings) with inorganic fertilizer (urea) on the vegetative growth of Amaranthus dubius. The data obtained showed that, levels of all parameters measured for both the organic and inorganic fertilizers ranges; Stem length (7.5-64.2) cm, Stem width (2.4-8.1) cm, Leaf length (8.0-19.3) cm, Leaf width (3.3-14.2) cm and Number of leaves per plant (09-34). The mean values for the stem length, stem width, leaf length, leaf width and number of leaves per plant were evaluated and found to be higher in plants grown with urea treatment compared to values obtained from the treatments with organic manures. Data were analyzed using One-way Analysis of Variance (ANOVA) and the results were expressed as percentage difference, the differences between the mean values were determined at 95% confidence. Inorganic fertilizer resulted in significant effects at (p<0.05) compared to values obtained from the organic manures.
