In the present study, chlorophyll ‘a’, chlorophyll ‘b’ and total chlorophyll was found to be influenced by the application of essential nutrients particularly, N, S and Fe. Lower chlorophyll concentration was found in early immature and later at senescence leaves. Total chlorophyll in canopy increased during the vegetative growth period, reaching a maximum close to tasseling stage and then decreased during reproductive and senescence period. Among the various treatments (F5) . application of 100kgN,50kgP,30kgS and 20kgZn through soil and foliar spray of Fe@2% showed maximum concentration of chlorophyll ‘a’, ‘b’, total chlorophyll and carotenoids followed F4, F3, F2, F1 and F0. | Study of multinutrient effect on growth, plant pigment concentration and yield of maize (Zea mays)
