Effects of Stump Density, Fertilizer on Rice Crop Quality and Harvest Amount in 2015 Investigated with Drone Mounted NIR Camera Data
Authors: Arai K, Gondoh K, Shigetomi O, Miura Y
Effects of stump density, fertilizer on rice characteristics (culm length, ear length, ear density, rice leaf greenness, water content, protein content, weight density) are investigated just before harvest of rice crops in 2015 with drone-mounted NIR camera data. Through experiments at rice paddy fields which is situated at Saga Prefectural Agriculture Research Institute SPRIA in Saga city, Kyushu, Japan, it is found that protein content in rice crops is highly correlated with NIR intensity or reflectance of rice leaves. Other than the protein content, culm length, ear density and weight density of rice crops are also correlated to NIR reflectance. Therefore, harvest amount of rice crops can be estimated with NIR reflectance. It also is found that ear length and water content in rice crops are not correlated with the NIR reflectance of the rice leaves while rice leaf greenness is correlated to the NIR reflectance.
