Experiments were conducted during the summer of 2002 at the Rice Research and Extension Center, Stuttgart, AR, to evaluate: 1) various timings of sequential applications of imazethapyr at 0.063 lb/acre (4 oz Newpath/acre) in conventional and staleseedbed rice planting systems utilizing Clearfield ‘CL-161’ and 2) the timing of clomazone application at various rates and timings in conventional ri...

Proper selection of energy-efficient agricultural machinery helps to reduce drudgery, increase cropping intensity and time required for field preparation. With conventional tillage implements, multiple passes are obtain desired seedbed which soil compaction due repeated movement tractor in field. combined implements two or more fuel energy In this paper, various researches on active-passive pas...

the introduction of canola (oilseed rape; brassica napus l.) as a new source of vegetable oil production in iran prompts evaluation of the performance of this crop under different tillage systems. a field experiment was conducted to determine the impact of depth and intensity of tillage on soil physical properties, crop establishment and yield of irrigated winter canola in a loam soil (typic ha...

Conventional seedbed preparation is based on deep ploughing followed by lighter and finer secondary tillage of the superficial layer, normally performed machines powered tractor’s Power Take-Off (PTO), which prepares in a single pass. Conservation methods are wide range interventions, such as minimum or no-tillage, means with passive action working tools require two more passes The aim this stu...
