The field experiment was conducted at VNMKV Parbhani for two years in maize crop with variety African tall which comes under semi-arid tropics with annual rainfall ranging from 700 to 900 mm in VNMKV Parbhani. Chlorophyll is the most important independent factor affecting spectral reflectance. In growing crop on an average for chlorophyll â€˜aâ€™ was from 0.12 to 0.29 and 0.13 to 0.34 and for chlorophyll â€˜bâ€™ concentration of maize leaves increase from 0.52 to 0.76 mg g-1 and 0.57 to 0.74 mg g-1. However total Chlorophyll concentration in maize leaves about 0.64 to 1.04 and 0.67 to 1.09 mg g-1 in two successive year. At 60 days after sowing chlorophyll a, b and total chlorophyll concentration decreases may be due to stage of maturity. Further, only nitrogen fertilization contributed significantly to total chlorophyll production followed by the additional P + S + Zn + Fe fertilizer (Treatment F5). With addition of each nutrient application (from treatment F1 to F5) there was increase in chlorophyll content in maize.
