Impact of plant growth regulators and organic fertilizer on growth and biochemical composition of Trigonella foenum-graceum L.
M Balakrishnan, A Arunprasath
The present experiment was carried out to assess the effect of organic manure and Plant growth regulators on morphological changes and biochemical composition of fenugreek. The experiment comprising of Control, Organic manure and three different Growth regulators such as IAA (Indole Acetic Acid), IBA (Indole Butyric Acid) and NAA (Naphthalene Acetic Acid). These three growth regulators are taken in four different combinations such as NAA+IAA, IAA+IBA, IBA+NAA and NAA+IBA+IAA. The hormones were prepared with distilled water and treated to the plants. The plants were irrigated with tap water regularly for 30 days. After 30 days the fresh plants were taken for the further analysis like Morphological studies and Biochemical analysis. The results reveals that the morphological parameters such as root length, shoot length, leaf area, fresh weight and dry weight are increased in the treatment of NAA+IBA, and in biochemical analysis chlorophyll, carotenoids, total sugar, starch, protein and amino acid contents were increased in plants treated with organic manure, when compared to all others treatments.
