Lolium rigidum Gaud. is one of the most common weed species in winter cereals in Northeastern Spain. Herbicide resistance has been growing since the mid 90’s and exclusive herbicide use is not enough in many cases, so that it is necessary to combine as many control tools as possible. Six field trials have been conducted during the cropping seasons 200102, 2002-03 and 2003-04 on winter cereal in...

Cropping systems like organic farming, selling products at a higher price and promoting environmental sustainability by reducing fertilizer and pesticides, can be more profitable than conventional systems. An economic evaluation of three cropping systems in a seven year period experiment was performed, using a common rotation (fallow-barley-vetch-durum wheat) in a semi-arid rainfed field of Spa...

A rotary tiller or rotavator is active tillage equipment used to prepare farmland for sowing seeds, weeding, mixing manure and fertiliser into the soil, crushing soil blocks, etc. Compared with conventional farming, advantages of this are rapid seedbed preparation reduced draught. Nowadays, utilisation rate tillers has increased. However, blades key component that engages in tiller. These inter...

Abstract Field experiments were conducted in Al-Muthanna Province, Iraq order to evaluate the Body parts discomfort score and physiological cost of tractor operator during tillage operation while using mould board plough. Three subjects represented 50 th percentile their population chosen for this study. We used Corlett Bishop Technique degree various body parts. According findings, both BPDS H...

The purpose of this research was to developed a program in visual basic software for predicting tractor implement performance combination. A conventional tillage system with mounted mouldboard plough and three bottoms used collect data from Chery (Model RM750) four-wheel drive. soil texture class were determined laboratory. Soil cone index value measured using SpotOn digital compaction meter. o...
