Development of an in-season nitrogen application dose estimation algorithm for cotton using multispectral imaging-based nitrogen adequacy index
Y. G. Prasad
Managing within-field variability in cotton fields for precision nitrogen (N) management is difficult. The development of multispectral sensors and image data analytics offers a solution to addressing the issue. During the Kharif (monsoon) season of 2021 and 2022, field experiments were conducted at the ICAR-Central Institute for Cotton Research, Regional Station, Coimbatore, Tamil Nadu, involving seven N levels (25%, 50%, 75%, 100%, 125%, 150%, and 200% of the prescribed N-dose (80 kg ha−1)), a
