DIAGNOSIS OF MAGNESIUM AND IRON DEFICIENCY IN GERBERA THROUGH VISUAL SYMPTOMS
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 55
Abstract
A pot experiment was conducted using Gerbera as a test crop to evaluate the importance of iron (Fe) and magnesium (Mg) in production of Gerbera. The experiment was laid out with 15 treatment combinations including T1(H1 to H5) as control (complete nutrition), T2(H1 to H5)excluding magnesium and T3(H1 to H5) excluding iron, where H1 to H5 represents the days of harvesting at 115, 130, 145, 160 and 175 days after transplanting (DAT) respectively. Development of chlorotic spots started in T2H3 and T3H1, progressing gradually into interveinal chlorosis towards the end of the experiment as compared to control. Root length and the development of color in petals were found to be less in the treatment combinations where certain nutrients were excluded.
