Abstract
Effects of seasonal variation and nitrogen treatments on nodulation and nitrogen fixation behaviour in Pongamia pinnata. Nodulation behavior and nitrogenase activity were studied in relation to nitrogen treatment (i.e. 0 40 80 100 kg N per ha) and seasonal variations in Pongamia pinnata seedlings. A marked increase in the nodule biomass per plant and nitrogenase activity was observed in the rainy season followed by winter and summer. Two peaks one small in early summer and another large during the rainy season were observed in nitrogenase (g superscript minus 1 fresh wt. h superscript minus 1 and pl superscript minus 1 h superscript minus 1) activity. However no definite trend was observed due to the different nitrogen treatments on the nodule biomass and nitrogenase activity but 40 kg N per ha was observed to be more effective than the others.
