Abstract: The present investigation was carried out for developing visual symptoms of macro and micro nutrient deficiencies in Gerbera through solution culture. Plants of Gerbera var. Savannah were treated with complete Hoagland solution and individual macro and micro nutrient deficiencies were incorporated with a complete nutrient formula minus one of the nutrients. Withholding of different nutrients from the nutrient medium resulted in characteristic visual symptoms on foliage and growth of Gerbera plants. Among macro nutrients, nitrogen deficiency appeared first which resulted in yellowing of older leaves. Phosphorous deficiency resulted in dark green leaves, potassium deficiency appeared as tannish brown necrosis all along the margins of older leaves, calcium deficiency appeared as leathery, brittle and pale green younger leaves, magnesium deficiency exhibited as intervienal chlorosis on older leaves and sulphur deficiency was expressed as uniform chlorosis. Among micronutrients, copper deficiency was first to appear as distorted young leaves, boron deficiency resulted in marginal necrosis of leaf apex on newly emerging leaves, iron deficiency appeared as interveinal chlorosis on younger leaves and zinc deficient plants expressed symptoms as interveinal chlorosis on older leaves. Manganese was the only nutrient which did not express any visual deficiency symptom but content was reduced when compared with plants grown in complete nutrient solution.
