적절한 질소 시비는 작물에 초형을 개선하는 한편, 엽록소 유지에도 도움을 주어 엽노화를 억제하고 광합성도 증대시켰다. 드론을 활용해 얻어진 잎의 RGB 값은 4월 29일에서 추비량 증가에 따라 RGB 값의 뚜렷한 차이를 나타내 단순한 엽색 분석도 작물의 생리적 상태 평가에 활용할 수 있음을 보여주었다. 휴대용 측정기를 이용한 실험에서 추비 조건에 따른 NDVI와 SPAD 값은 3월 19일에 큰 차이 확인할 수 없었다. 그러나 초분광카메라를 통한 분석에서 추비량 증대에 따라 780 nm보다 큰 파장대인 NIR 영역에서 반사율 증가가 확인되었다. 이는 시비 효과가 명확히 드러나지 않는 생육 초반에도 초분광카메라 활용해 작물 상태를 진단할 수 있음을 보여준다. 포장에서 추비 수준이 낮을수록 4월 29일에는 가시광선 영역의 반사율이 증가하고, NIR 영역의 감소가 확인되어 시비에 따른 영향을 확인할 수 있었다. 초분광카메라를 이용한 식생지수 확인으로 엽록소 함량, 질소 부족 정도, 광합성 상태 분석에 근거한 시비 효과 평가가 가능하였다.
