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 seedling growth and vigour of Albizia procera 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. Seedlings treated with N @ 50 mg kg^-1 soil + Bio-fertilizer 0.5 ml kg^-1 soil (N₆) and kept under Net house (75% Green shed-net) (E₂) recorded higher survival (97.07%), shoot height (23.20 cm), collar diameter (3.67 mm), number of rachis (16.00), total leaflet area (250.47 cm²), length of main root (44.27 cm), total fresh weight of plant (12.17 g), dry weight of plant (6.84 g) and seedling quality index (1.92). On the other hand maximum root: shoot ratio (1.93) was recorded by the interaction of N₁- (Control-Tap water) and E₁- (Open Environment); whereas, maximum sturdiness quotient (6.65) was recorded under treatments N₁- (Control- Tap water) and E₂- Net house (75% Green shed net). Hence this treatment can be used for quality seedling production of Albizia procera.
