Landfill leachate was collected from a hole dug 10 m away from the waste dump site for laboratory analysis. Soil samples were also collected from four trial pits in the dumpsites at the depth of 0.3, 0.6 and 0.9 m and at a distance of 10, 20, 30 m and the control 100 m away from the dumping site. The collected soil samples were subjected to physiochemical and geotechnical analysis. This includes particle size distribution, pH, EC, total organic carbon, total organic matter, extractable micronutrients and heavy metals (Zn, Cu, Mn, Fe, Pb, Cd, Cr, Cl and Ni), Attterberg limits, specific gravity and hydraulic conductivity. The physicochemical concentration was then compared with the maximum allowable concentrations of chemical constituents in uncontaminated soil. The Laboratory analysis shows high value of pH (8.51) DO (0.17 mg/l), COD (68mg/l), BOD<sub>5 </sub>(324 mg/l), Pb (0.31 mg/l) and Cd (0.06 mg/l) in the leachate sample. The physical properties of the soil near the dumpsite indicated that the soil belongs to sandy loam in texture. pH (6.3-8.32), Electrical conductivity (241-2018 s/cm), total organic carbon (0.24-2.16 ) and total organic matter (0.41-3.73%) were higher near the vicinity of the dumpsite and decreased with increase in the depth and distance. Extractable micro nutrient and heavy metal concentration (Zn, Cu, Mn, Fe, Pb, Cd, Cr, Cl and Ni) were also found to be high near the dumpsite and decreased along the soil depth and distance from the dumping site. The variance in the geotechnical properties of soil revealed by the test results was impacted by the dumped municipal solid waste. These effects decrease with increase in depth. These findings will help in facilitating the invention and introduction of site specific technologies.&nbsp;</p> S. A. Nta M. J. Ayotamuno A. H. Igoni R. H.

Farm land soil, forest soil and granulated iron stone soil were sourced within the college premises and FRIN/JICA plantation. <em>Jatropha curcas </em>seedlings were sown on the different soils and each was replicated eight (8) times. The experiment was laid out in Complete Randomized Design (CRD). Growth parameters were collected forth nightly and was subjected to Analysis of Variance (ANOVA) and Duncan Multiple Range Test (DMRT). Results revealed that there are significant (P&gt;0.05) difference in the height, stem diameter and number of leaf among the three different soil for the growth assessment. The growth rate recorded from the farm land soil are statistical higher (P&gt;0.05) in leaf width, plant height and stem diameter than the other two soil while the growth parameters assessed were significantly lower (P&gt;0.05) in iron stone soil and forest soil. It is recommended based on the parameters assessed that soil from the farmland gives the best result for raising and nurturing of <em>J. curcas</em> in the nursery without addition of any plant nutrient media.</p> A.

The effectiveness of this strategy however, has been constrained by the low soil fertility status of soils in Malawi, necessitating the use of mineral fertilizer to supply nutrients to the soybean for increased productivity. Alternative strategies like foliar feeding of nutrients to improve grain yields are yet to be widely promoted due to lack of research evidence. Therefore experiments involving the soybean were conducted during the 2016/17 cropping season, laid in a randomized complete block design (RCBD) replicated four times, at Bvumbwe, Bembeke and Chitala&nbsp; in Malawi to evaluate yields response to foliar feeding using a foliar fertilizer (Allwin-legumes). Agronomic data were analyzed in Genstat Discovery Edition 4 and were subjected to analysis of variance at 95% level of confidence. Means were separated using the least significant difference (LSD<sub>0.05</sub>). Generally, the result indicate that foliar feeding produced significantly higher (p&lt;0.05) grain yields ranging from 33.7-364.7%, above the control across the different agro-ecological zones. The result underscores the importance of judicious and methodical application of nutrients to soybean under the changing climate and conditions of low soil fertility. In general, foliar feeding using Allwin fertilizer particularly when conducted twice can increase significantly soybean productivity in Malawi. The grain yields increase is attributable to the enhanced crop growth and development through foliar supply of nutrients.</p> Austin T.

The red brown terrace soil of Tejgaon was silty clay loam having pH 5.6. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. The experiment comprises 4 levels of potassium in the form of MoP (0, 20, 40 and 60 kg potassium/ha). The results revealed that different levels of potassium showed significant variations on the yield and yield components of BARI Bush Bean-2. The treatment K<sub>40</sub> (40 kg potassium) gave the maximum pod length (10.90 cm), pod diameter (2.95 cm), average single pod weight (5.49 g), total pod weight per plant (25.37 g), pod yield per plot (1795.83 g) and pod yield per hectare (4.38 ton). Thus the results of the experiment suggested that the use of 40 kg potassium produced highest yield of BARI Bush Bean-2 in red brown terrace soil of the Tejgaon series.</p> Basudeb Roy Alok Kumar Paul A.
