Abstract/Description: | Azotobacter, phosphate solublizing bacteria (PSB) and phosphate solublizing fungi (PSF) population were assessed in soil under five different crop species grown in irrigated Indian arid environment. Azotobacter was most abundant in arid soil (5.6 × 104 CFU g-1 soil) in comparison to PSB (1.9 × 104) and PSF (1.3 × 104). The population of these organisms varied among the crop species. Maximum population was recorded for uminum cyminum L. followed by Brassica oleracia L., Capsicum annuum L., Triticum aestivum L. and Brassica juncea L. Soil properties were significantly correlated with Azotobacter population. Of the various soil properties, pH and EC (1:2 soil: water) showed negative correlation, while organic carbon (OC), Olsen’s P and NH4OAc extractable K were positively correlated with Azotobacter population. Further, Azotobacter population decreased drastically with the increase in ECiw and SARiw of applied irrigation water. In PCA biplot, Azotobacter population was aligned with OC, Olsen’s P. Brassica oleracia was most efficient in hosting P solubilizers while Cumin cyminum and Brassica oleracia were most efficient in forging mutualistic association with Azotobacter. Regression analysis indicated that about 50, 42, 42, 52 and 16 per cent variation in Azotobacter count was attributed to pH1:2, EC1:2, OC, Olsen’s P and NH4OAc-K, respectively. |
