Abstract

The present study was carried out to investigate the effect of different levels of nitrogen (N) alone and nitrogen in combination with Rhizobium inoculation (R) on root nodulation, N content and N uptake by Albizia procera seedlings under variable environmental conditions. The experiment was conducted in polythene bags with eighteen treatment combinations, comprising of six levels of fertilizer viz., 0 mg N, 25 mg N, 50 mg N, 0.50 ml R, 25 mg N + 0.5 ml R and 50 mg N + 0.5 ml R per seedling, respectively and three distinct growing environments (E) viz., open, net house and poly house, respectively. The maximum number of nodule per plant (67.00), nodule diameter (3.72 mm) and fresh weight of nodule per plant (1.53 g) at 90 DAT were observed under the interaction of 0 mg N per kg of soil and seedlings kept in the Net house. However, maximum N content in both shoot (1.54%) and root (0.53%) were observed in 25 mg N kg-1 soil + 0.5 ml Rhizobium kg-1 soil in Net house condition. Whereas maxi

Conclusion

The maximum number of nodules per plant, maximum nodule diameter per plant and also the maximum yield of nodules per plant i.e. maximum fresh weight of nodules per plant (g) were observed under the interaction of N1 (Control- Tap water) and E2- Net house (75% Green shed net). Higher nutrient (N) content in both shoot and root was recorded in treatment N5 (N-25 mg kg-1 soil+ Bio-fertilizer 0.5 ml kg-1 soil) in conjunction with E2- Net house (75% Green shed net). Whereas; maximum N uptake by the plant was observed in treatment N6 (N-50 mg kg-1 soil + Bio-fertilizer 0.5 ml kg-1 soil) kept under E2- Net house (75% Green shed net). It is also concluded that nitrogen affects nodulation at the initial stage of A. procera seedling. Rhizobium + N treatments increased the nutrient status. Therefore, this combination can be used for quality seedling production of A. procera.
