Investigating lodging in spearmint with overhead sprinklers compared to drag hoses using entropy values from low altitude RGB-imagery
《Information Processing in Agriculture》2022年第2期335-341,共7页Behnaz Molaei Abhilash Chandel R.Troy Peters Lav R.Khot Juan Quiros Vargas 
Lodging occurs when the crop canopy is too heavy for the strength of the stem and it fallsover onto the ground. This decreases crop yield and quality, and it makes harvest difficult.A research experiment was set up in...
