Assessing Growth Rate of Jatropha Plant (Height and Diameter) Under Different Method of Propagation in Nyankpala In Northern Region Ghana

ABSTRACTThe study was carried out at Nyankpala in the Northern region of Ghana from November 2012 to April 2013 to investigate the growth rate of Jatropha plant under two methods of propagation (seeds and cuttings) that best support the growth of the plant. Data on the survival rate, height and diameter were collected and other data were obtained through observation. Each of the plantation was divide into nine (9) plots and five plots were selected randomly for the studies. Each of the planta...

DISCUSSION ON THE CROP WATER REQUIREMENT, PERIOD OF PLANTING, DAYS TO HARVEST (DEVELOPMENTAL STAGE) AND AREAS PLANTED OF THE FOLLOWING VEGETABLE (FRUIT) CROPS: TOMATO, ONION, OKRA, PEPPER

One of the most critical inputs to vegetable (fruits) production in semi-arid areas, dry season farming and nursery establishment is water. During the dry season or off season, the source of water for vegetable growing is from irrigation while in the wet season, rainfall is the source of water. Young vegetable seedlings in the nursery or in the field should be watered in the early morning or in the evening. Watering should be done before transplanting particularly in the&n...

A Review of Soil Dynamics in Traction Studies

As the world population increases more than ever before and increasing demand on food, feed andfiber, and security, the number of off-the-road vehicles is rapidly increasing for agriculture, forestry,military, mining and construction industries. Many researchers have studied and still investigatingtraction as it relates off-road vehicles and publications abound especially from developed countriesof Europe, America and others. In our generation scientists are trying to put robotic vehicles on ...

Impact of Petroleum Industrial Degradation on the Yield of Agricultural Produce

AbstractThe study focused on the impact of petroleum industrial degradation on agricultural produce in Ilaje Local Government of Ondo state. Four research questions were developed in conformity with the purpose of the study. The study adopted survey research design. Questionnaires were administered to elicit information on crop productivity, livestock productivity, forest and aquatic organisms and therefore the strategies to cope with the impact of petroleum industrial degradation. A total of...

EFFECT OF SALINITY ON THE PHYSIOLOGICAL BEHAVIOR OF THE OLIVE TREE (VARIETY SIGOISE)

Salinity is a major problem directly affecting the ecological balance and the development of agriculture in the Mediterranean basin, particularly North Africa. This phenomenon is considered as the most important abiotic factor limiting crops growth and productivity, degrading and polluting soils in arid and semi-arid. In order to study the influence of salinity, on the physiological parameters and to assess the potential of adaptation of the olive tree in a saline environment, three parcels c...

Evaluation of yield characteristics cum determinant factors in earth mound method of charcoal production using billet of Acacia nilotica

ABSTRACTTree residues are generated in large quantity in our environment. Nowadays, adding value to these residues could make them become item of economic importance. The aim of this study is to adapt a traditional method of charcoal production (Earth Mound) in order to add value to the tree residues generated in University of Ibadan with a view to enhance the benefit derived from them. The billets of Acacia nilotica were converted from both wet and dry wood samp...

Charcoal Yield from Urban-Tree Residues Generated in University of Ibadan, Nigeria using Earth Mound Method

Abstract The cost of managing ornamental and naturally growing trees in the University of Ibadan, Nigeria, is becoming challenging. Adding value to the residues from these trees with a view to enhance its economic value will minimize the management cost. This study adapted Earth Mound method of charcoal production to add value to tree residues generated in the University of Ibadan to enhance its economic value. Mixed residues of Acacia nilotica (Acacia), Albizia zygia (Ayunre) and Melicia exc...

Dimensional Stability and Mechanical Properties of Wood Plastic CompositesProduced from Sawdust of Anogeissus leiocarpus (Ayin) with RecycledPolyethylene Teraphthalate (PET) Chips

ABSTRACTWood Plastic Composite panels were produced using a locally fabricated extruding machine at a temperature of about 170°C-200°C. the Sawdust of Anogeissus leiocarpus(Ayin) and Recycled Polyethylene Teraphthalate (PET) Chips were mixed in the ratio 1:1 to 1:5 and densities of 770.58 kg/mm3, 888.65 kg/mm3, 1,114.71 kg/mm3, 1,117.58 and 1, 141.84 kg/mm3 respectively. The quantity of recycled polyethylene teraphthalate (PET) Chips and sawdust used in the panels produc...
