A field experiment was conducted to evaluate the effect of Azotobacter and L-tryptophan (L-TRP) application on the growth, yield and nitrogen content of wheat (Triticum aestivum L.) crop. Two levels of L-TRP (10 -3 and 10- 4 M) were tested with and without Azotobacter inoculation in a fertilized (NPK: 125-100-60 kg ha -1, respectively) field. Results revealed that Azotobacter inoculation and L-TRP application significantly affected the wheat crop, however, their combined application produced more pronounced effect as compared with their separate application. Combined application of Azotobacter and 10 3 M L-TRP significantly increased the grain yield (21.3 %), straw yield (20.7 %), plant height (5.8 %), number of tillers (15.3 %), number of spikelets spike -1 (12.3 %), spike length (11.6 %), 1000-grain weight (6.4 %), nitrogen concentration in grains (31.4 %) and straw (26.1 %), and total nitrogen uptake (56.3 %), compared with untreated control. |
