A nursery experiment was conducted to study the beneficial effect of various organic fertilizers such as vermicompost, Azospirillum, farmyard manure, agricultural waste, organic manure, wood ash and neem cake on growth and biochemical characters of pigeon pea Cajanus cajan. The results revealed that there was significant response in both growth as well as biochemical parameters of pigeon pea. Amendment of organic fertilizers was increased the shoot length in plants with neem cake and in the case of root length, the effect was higher neem cake followed by wood ash. All the organic fertilizers greatly affected the fresh weight of pigeon pea over the control. Among them, the plant fresh weight was higher with neem cake followed by organic manure. The effect was directly reflected in the plant dry weight also. In addition to growth characters, the biochemical characters of pigeon pea such as chlorophyll, carotenoid, protein, glucose, free amino acid and in vivo nitrate reductase activity were higher in organic fertilizers treated soil compared to the control plants.
