Assessment of heavy metals in the environment is an important tool to evaluate the risk of toxic metals to humans. In order to achieve this, soil and plant samples were collected within the vicinities of auto mechanic workshops in Gwagwalada area council at five (5) sites used as the study areas and a control site. The soil and plant samples were analysed for five heavy metals (Cd, Cu, Ni, Pb and Zn) using Atomic Absorption Spectrophotometry. The range of mean heavy metal concentration of the Auto mechanic soils were: Cd: 15.73 - 35.89 mg/kg, Cu: 112.05 - 170.42 mg/kg, Ni: 58.25 - 136.48 mg/kg, Pb: 105.59 - 316.57 mg/kg, Zn: 116.16 - 349.49 mg/kg while the range of mean heavy metal concentration in plants at the experimental sites was: Cd: 1.75 - 10.56 mg/kg, Cu: 25.38 - 79.42 mg/kg, Ni: 28.93 - 47.98 mg/kg, Pb: 5.48 - 33.48 mg/kg, Zn: 35.61 mg/kg - 111.54 mg/kg. The study indicated that consumption of plants grown on these sites could pose health hazard to man.

Water deficit is one of the most important environmental factors affecting agricultural production especially in rainfed cropping systems. To understand how morphological and physiological factors interact, a study was conducted to assess the responses of leaf stomatal parameters to water status and its relationship with chlorophyll content in False Horn plantain. Each plant was grown in 120 kg soil in bowls and subjected to varying watering regimes (10 ml, 15 ml, 20 ml, 25 ml, 30 ml and control) without allowing natural rain into the bowls except the control. The result showed that False Horn plantain was sensitive to soil moisture stress; and this was reflected in changes in reduced growth through reduced plant height. The study also showed a systematic growth of the leaf with time. The patterns of leaf length growth remain similar under the different watering regimes. There was a significant difference in the leaf growth between the control and the varying amount of watering. The undulating pattern, however, showed that other factors could influence the leaf length. The large leaf area used for transpiration in Apantu is likely to be affected by soil water deficit. There was no correlation, however, between the leaf length to width ratio and the soil moisture content. The study further revealed that leaf length and width in False Horn plantain increases with growth, however, leaf sizes started to reduce when the plant approaches the flower primordial stage of growth. Watering regime influenced stomatal opening and closure in False Horn plantain and chlorophyll content. Leaf chlorophyll content was not highly influenced by the varying watering regimes; indicating that the presence of laticifer cells may be a factor for water stress tolerance in plantain.

In pot plant production, balancing the air and water content in the medium is one of the largest problems. The ‘root restriction’ effects of the plug cells on seedling growth during nursery could increase after transplant and thus limits pot plant productivity. Two plug cell size (limiting and non-limiting ones) and two growing media were tested. Different concentrations (0, 1.5 and 3.0 kg m-3) of the hydrophilic gel potassium acrylate (Stockosorb®, Evonik, Germany) were added at transplanting to create growing media with different container capacity. The aim of this work was to evaluate the physiological mechanisms involved when two different pre-transplant cell volumes (50- and 288- cells-plug tray-1) and two post-transplant growing media amended with different potassium acrylate concentrations (0, 1.5 and 3.0 Kg m-3) were used. The hypothesis tested was that the negative effects of combined abiotic stress sources (pre-transplant cell volume and growing medium quality) that reduced air-filled porosity and affect Impatiens wallerana growth and yield are mainly associated with a decrease in root size. Our results showed that the root restriction related to cell volume and growing medium quality reduced air-filled porosity but in different magnitude according to the growing medium tested. We found a decrease in the relative rate of leaf area expansion (RLAE), the relative growth rate (RGR), the net assimilation rate (NAR) and glucose content, and an increase in water-holding capacity. We also found positive relationships between the previous mentioned growth parameters and an increase in root dry weight. Since the responses to the different plug cell volume and growing medium to overcome the root restriction were the same as those found in other experiments in plants sprayed with exogenous cytokinins, we speculated that endogenous cytokinins are involved in plant growth.

Soil is one of the most precious national resources and the knowledge of soil resources of an area is vital for optimizing land use and any developmental activities. Remote sensing and GIS have emerged as extremely valuable tools to study the soil resources, their potential for various use and problems. Hence an attempt has been made to study the soils of some soils of the Eastern Desert Part of Sohag Governorate and map them based on the fertility capability classification (FCC) using remote sensing and GIS. False color composite (FCC) of Landsat ETM imageries were visually interpreted incorporated with Digital Elevation Model (DEM) which generated from the Shuttle Radar Topographic Mission (SRTM). Different imaging interpretation units were identified and soil pedons were examined in each unit. Horizon wise soil samples were collected and analyzed for physiochemical properties by adopting standard procedures. Based on the results, the major landforms of the studied area were described as Wadi Bottom (WB), Bajada (B), Alluvial Fans (AF), Tableland (T), Gently Undulating Sand Sheet (GUS) and Undulating Sand Sheet (US). The type, substrata type and condition modifiers were also identified for each landform. The main condition modifiers of the study area were texture (S), low CEC (e), K deficiency (k), calcareous (b), salinity (s), dry condition (d), gravels (r) and low organic matter (m). Relevant FCC units were assigned to various landforms based on the type, substrata type and condition modifiers. A utility map was prepared using GIS with the FCC units, their limitations and extent distribution. Generally, the fertility of these soils was poor on account of low organic matter, total nitrogen, available phosphorus, potassium and micronutrients. Also, the water retentively was not satisfactory by the virtue of poor organic matter and higher percentage of coarser fraction. Based on the fertility constrains various soil management practices have been suggested to optimize the land use.
