Abstract

The present work aimed to study the influence of three gradual
rates of nitrogenous fertilizer (ammonium nitrate; NH4NO3) and potassium
humate at four doses and their interactions on vegetative growth and chemical
constituents of Calotropis procera plants. The obtained results showed that all
morphological characteristics i.e. plant height, stem diameter, number of
branches and leaves per plant, leaf area per plant, plant fresh and dry weights,
root fresh and dry weights were inceased by application of different rates of
NH4NO3 and potassium humate fertilizer or their combinations. Also, plants
treated with NH4NO3 and potassium humate fertilizers showed a significant
increase in the contents of chlorophyll A and B, carotenoids, total
carbohydrates(%), N%- P%- K% and total alkaloids of Calotropis procera
leaves as compared untreated (control) plant. While total phenolic and total
flavonoids contents were decreased with fertilization by different rates of
NH4NO3 and potassium humate. The highest values of total phenolic and total
flavonoids contents were obtained with applied the lowest fertilizer rates of
NH4NO3 (1g/ plant) and potassium humate at zero level.
