Abstract

We investigated the potential use of real-time kinematic (RTK) global positioning system (GPS) to determine seedling distribution and plant growing area mapping by evaluating the obtained level of accuracy. High-accuracy seed and plant growing area mapping can potentially be used in the evaluations of seeding machine performance, weed control, and plant-specific crop management. Actual plant locations were determined using a measuring tape. Seedling locations, plant growing area, and shape ratio values were compared between RTK GPS and tape measurements. RTK UPS was shown to be reliable to monitor millimetre-level accuracy for seedling locations, as well as for generation of shape ratios and growing areas of cotton, soybean, and watermelon plants.
