Effects of bio-fertilizers (Bacillus lentus – Pseudomonas putida) and different rates of Triple Superphosphate fertilizers on some attributes of sugar beet (Beta Vulgaris L.)

Abstract

The aim of this study was to determine both combined and individual effects of phosphorus bio-fertilizers (Bacillus lentus – Pseudomonas putida). Additionally, the study also monitored the different effects of triple superphosphate fertilizers on agronomic and quantitative characteristics of sugar beet. The factorial experiment approach (RCB design) was used to conduct this experiment. Furthermore, cultivars 7233 and BR1were used as experimental materials to enhance the evaluation of the different fertilizer treatment. An evaluation of the experiments result showed minimal adverse effect, of application of phosphorous fertilizers to phosphorous rich soils. In particular, continued application of phosphorous fertilizer despite its improved values, will results into plant nutritional stress. In conclusion, this experiment results indicated that BR1 cultivar in comparison to 7233 cultivar BR1 had improved qualitative and quantitative characteristics like dry weight, leaf area, high sugar content and better tolerance to increased application of phosphorus fertilizer. Consequently, increased application of phosphorus fertilizers to phosphorus rich soils resulted to decreased yield output. However, biological fertilizer in comparison to its mineral counterpart had reduced impacts on the traits
