tailieunhanh - Study of multinutrient effect on growth, plant pigment concentration and yield of maize (Zea mays)

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)
