Phoma stem canker is a damaging disease of oilseed rape (Brassica napus) that causes annual yield losses to UK growers worth approximately £100 million, despite the use fungicides. In UK, sown in August/September and harvested following July. The epidemics are initiated by ascospores released from Leptosphaeria spp. pseudothecia (ascocarps) on stubble autumn/winter. Control this reliant cultiva...
Agave bagasse was successfully separated into fractions that were used in sheep feeding trials. Agave bagasse can be substituted for corn stubble in the sheep's diet which resulted in improved weight gain. Agave bagasse was also processed into long and short fiber fractions with a hammermill and fiberboards of medium and high specific gravities being produced. Medium specific gravity agave fibe...
Facial perception research has benefited from the use of computer graphic methods, such as facial image prototyping and transformation. This paper describes new methods for improved prototyping and transformation of skin textures including wrinkles and stubble. We use a biologically inspired wavelet transform to capture the textural detail in different facial regions at multiple spatial scales ...
Sunflower has historically been an important crop in Central Queensland. In recent years the sunflower area in Central Queensland has been reduced due to low and variable prices and increased competition from alternate summer crops. Issues of tall persistent stubble that provides little ground cover and a lack of in-crop weed control options have also contributed to declining popularity of sunf...
The levelling of the field surface after shallow tillage with a planar cutter, characterized by such qualitative indicator as combiness, is within limits allowed agrotechnical requirements. We have developed an original design plane cutter for tillage. has various options sharpening angle rack and mortar, which been optimized. Optimal according to criterion minimum energy consumption while obse...
Abstract For sowing grain crops on stubble, stubble seeders with tine coulters are used, which perform technological operations in one pass. However, they do not meet the requirements of agricultural machinery to ensure an even distribution seeds sub-spear space. The subsoil no-drill planting creates most favorable conditions for growth and development cultivated at same time, crop yields incre...
