A field experiment was carried out at the farm of ICAR-Indian Agricultural Research Institute, New Delhi during rabi season of 2014-15 and 2015-16. The study was conducted to observe response of wheat under reduced solar radiation. In this experiment, three wheat cultivars namely, HD 2967, WR 544 and PBW 502 were grown under five solar radiation reduction treatments i.e. R1 (control), R2 (20% shading), R3 (35% shading), R4 (50% shading) and R5 (75% shading) levels. Ground held spectroradiometer was used for spectral reflectnance measurement of wheat canopy. Finally normalized difference vegetation index (NDVI) was calculated for different treatments. The different regression equations between LAI -NDVI and fIPAR-NDVI were developed for different treatments for both years. The positive correlations were observed for all treatments during both years. Spectral radiance of blue band (400-500nm) was more inside the severe shading compared to mild shading and control. But spectral radiance of red band (620-700nm) was less inside the severe reduced radiation treatments in both the seasons.
