Effect of organic and inorganic nutrients on physiological traits of soybean (Glycine max (L.) Merr)

An experiment was conducted to study the effect of organic and inorganic nutrients on physiological traits of soybean during kharif 2009. The results indicated that chlorophyll and carotenoids are positively influenced by organic manures, the same trend was found for oil and protein content in seeds. Further, the secondary metabolites like total phenols were also positively affected by organic manures in comparison to inorganic fertilisers. Lower oxidative stress in organic manures applied plants supported the beneficial effect of organic manures on the physiological processes of soybean. However, the inconclusive outcome for free aminoacids warrants further investigation. Nonetheless, the quality parameters like oil and protein contents in soybean were improved under organic manures regime.
