Response of Nitrogen, Rhizobium and Cutting Management on Nodule Behaviour of Fenugreek

The experiment was carried out to study the response of nitrogen, Rhizobium and cutting management on nodule behaviour of fenugreek under West Bengal condition. The findings revealed that higher doses of nitrogen upto 40 kg/ha produced more number of nodules/plant (232.4) which is 20.2% increase over control. Seed inoculation with Rhizobium showed a marked increac;e (222.9). The highest nodule dry weight (0.832 g) was obtained with 40 kg nitrogen/ha. Rhizobium inoculation also resulted in significant increase in nodule dry weight/plant (0.767 g), whereas, it was only 0.710 g with uninoculation. The response of cutting was not significant. So far as the leghaemoglobin content was Loncemed it showed an increasing trend upto 40 kg/ha of nitrogen (225.58 mg/g). Whereas, with increasing doses of nitrogen from 0 to 60 kg/ha the dry metter/plant was increased, the highest being 13.09 g/plant with 60 kg/ha. The maximum green and seed yield (57.16 and 11.84 q/ha, respectively) was obtained with 60 kg nitrogen/ ha. There was a negative influence of cutting in seed yield.
