Development 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...

متن کاملDevelopment of a Novel Paddy Rice Herbicide Propyrisulfuron (ZETA-ONE)
Herbicides have made a large contribution to reducing the workload of crop production. While herbicides with various modes of action are currently used, sulfonylurea herbicides, which were developed starting in the 1970s, are in widespread use worldwide, and they hold the central position in weed control in Japan as paddy rice herbicides. However, as is the fate of agricultural chemicals that a...
متن کاملExpert System for Paddy Production Management
This paper presents an expert system for Paddy production management. This expert system gives advice to Paddy growers in Egypt to improve Paddy productivity. The system contains two main parts namely: strategic part and tactic part. The strategic part gives a strategic advice (i.e. list of agricultural operations) before cultivating Paddy crop. The strategic part contains four sub-systems name...
متن کاملAn Automatic Water Management System for Large-Scale Rice Paddy Fields
An automatic water management system for large-scale paddy fields has been developed. The purposes of that are to supply the paddy fields with water or drain water from that automatically, to decrease water consumption, and to have a good harvest. To accomplish the above purpose, developed system has five functions, (1) prediction of paddy growth stages, (2) water level control corresponding to...
