This study was conducted to model and optimise the efficiency of a disc plough on loamy-sand soil in South-East Nigeria aid farmers examine choose right ploughing implement based type for an effective bountiful production. The operational speed cutting depth were taken as factors efficiency. results revealed that highest field 80% noted when worked at 30 cm 5 km·h–1 while lowest 68....

Abstract Multistep excavations were implemented at the toe of a large-scale slope model, and surface displacements in measured to examine validity relationship between velocity acceleration proposed by Fukuzono for excavated slopes. The displacement increased both during after excavation, among which latter was due creep deformation under constant stress. rate increase initially high then decre...

Field trials were conducted at the Delhi Research Station, Ontario, Canada, on a Fox loamy sand soil during 1987 and 1988 to evaluate the effects of row application of the fumigants Telone II, Telone C-17, Vorlex Plus, and Vorlex Plus CP on the yield and quality of paste tomato (Lycopersicon esculentum Mill. cv. Ferry Morse 6203). The four fumigants were equally effective in controlling the nat...

The mobility of clomazone [2-(2-chlorobenzylo)-4,4-dimetylo-1,2-oxazolidin-3-one] in a loamy sand soil and a sand soil was studied in a soil column under laboratory conditions. Commercial clomazone formulation (Command 480 EC) and clomazone immobilized in an alginate matrix were used for a leaching experiment. For both formulations, the same dose of 2.0 mg of the active substance was applied. A...

Mount St. Helens volcanic ash was incorporated into a loamy sand greenhouse soil mix to produce concentrations of 0, 0.5, 1.0, 2.0, 4.0, 8.0, 25, 50 and 100% ash. Chemical and physical properties of the various mixtures were determined. Three experiments were conducted in a greenhouse to determine if volcanic ash had any influence on root-knot nematode survival and infectivity. Tomato, Lycopers...
