Eleven years of integrated weed management: longterm impacts of row spacing and harvest weed seed destruction on Lolium rigidum control
Long-term research aimed to determine whether narrow row spacing and harvest weed seed destruction, in combination with herbicide use, would be sufficient to drive a Lolium rigidum population to extinction. A trial was run from 1987 to 2013, with treatments including crop row spacings of 9, 18, 27 or 36 cm and crop residue burning or retention. Herbicides were applied to reflect regional practi...

متن کاملDevelopment and Evaluation of a Real Time Site-Specific Inter-Row Weed Management System
ABSTRACT- A real-time, site-specific, machine-vision based, inter-row patch herbicide application system was developed and evaluated. The image resolution was 640 × 480 pixels covering a total area of 350 mm x 240 mm of a field composed of four quadrants of 350 mm x 60 mm each. The image frames were processed by LabView® and MatLab®. The developed algorithm, based on weed coverage ratio and seg...

in order to study the effect of row spacing and plant density on quantity and quality yield of soybean in weed competitive condition, a field experiment was carried out at research farm of yasuj agricultural college in summer of 2011. experiment arrangement was split factorial base on randomized complete block design with three replication. the main factor included weed ( in two levels of contr...
متن کاملThermal Intro Row Weed Control Optimized Machine with Image Processing
Farming organic vegetable and crops have grown as a market desiring commodity. Weed control in farms has been costly and laborous and it has always been hard to achieve a proper weeding. A few chemicals are commonly applied in organic farming. Thermal weeding with flame burners seems a good solution; however, it has its own drawbacks, such as; damaging the main crops, low performance, being inf...
