| Abstract | ||||
| TO INVESTIGATE the effect of biofertilization using Pseudomonas ……fluorescens and cobalt on growth and productivity of guar (Cyamposis tetragonoloba L.) under desert soil conditions. A field experiment was carried out for two successive seasons of 2010 and 2011 at the agriculture experimental station at El-Kharga Oasis, New Valley Governorate, Egypt. Bradyrhizobium spp. was used to inoculate seeds of all treatments and control as base application. Pseudomonas fluorescens was used as seed inoculant and cobalt at concentrations (5,10 and 20ppm) as foliar application in single and mixed treatment with Pseudomonas. Obtained results indicated that, interaction treatment between P. fluorescens inoculation and cobalt foliar application (20ppm) had the highest record for guar plant growth parameters, yield and its components as well as mineral contents of seeds (N,P,K as macronutrients) and (Zn, Mn, Fe and Cu as micronutrient). Cobalt content in plant and seed, nodulation and its efficiency and microbial activity in guar rhizosphere. | ||||
