Abstract

A field and lab experiment entitled “Kinetics of 1-Aminocyclopropane-1-carboxylic -deaminase (ACCD) activity of Pseudomonas fluorescens, its population growth under different fermentation conditions and performance of the selected isolates on maize” was conducted at Laboratory of Microbes Research & Production Centre (MRPC) and the Research Farm, Department of Soil Science and Agricultural Chemistry, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur, Madhya Pradesh during 2018-19. The results revealed that the available nitrogen (N) content in soil at knee height, tasseling and silking stage, the treatment combination Temperature 28oC and pH 7.2 (T28+pH 7.2) isolates significantly increase the N content in soil with response of 21.5,17.3 and 14.4% over FUI (209, 196 and 166 kg N ha-1), respectively. Similarly, the isolates of T28+pH 7.2 significantly increase the available phosphorus (P) content at knee height, tasseling and silking stage in soil with response of 31.7, 23.2 and 26.4% over FUI (18.0,16.4 and 14.4 kg P ha-1). The isolates of T28+pH 7.2 significantly increase the available potassium (K) content in soil at knee height, tasseling and silking stage with response of 14.4, 10.1 and 10.4% over FUI (298, 278 and 264 kg K ha-1).
