EFFECTS OF Rhizobium phaseoli STRAINS AND MOLYBDENUM FOLIAR APPLICATION ON GROWTH AND YIELD OF COMMON BEAN (Phaseolus vulgaris L.) (Pages : 1 - 8)

A field experiment was conducted at Rice Research Station of Rasht, northern Iran, to evaluate the effect of molybdenum foliar application on common bean (Phaseolus vulgaris L.) growth and yield when inoculated with different Rhizobium phaseoli strains. A factorial combination of five strains of Rhizobium phaseoli [un-inoculated (control), seed inoculated with strain R122, R133, R136, and R147), and three foliar applications of molybdenum at the rates of [0 (control), 1.5 and 3 g L-1 of Sodium Molybdate Dihdrate] consisted the experimental treatments which were arranged in a randomized complete block design with three replicates. Analysis of variance indicated that the main effect of Rhizobium phaseoli strain was significant for plant height, pod yield, seed yield, 100-seed weight and biological yield, but not for pod number per plant, seed number per pod and harvest index. The main effect of molybdenum foliar application was significant only for pod yield, seed yield and pod number per plant. At the same time, the interaction between Rhizobium phaseoli strain and molybdenum foliar application was significant only for pod yield, seed yield, pod number per plant, and harvest index. Results indicated that Rhizobium phaseoli strain had different responses to molybdenum foliar application in regards to seed yield and pod yield. However, in most cases, molybdenum foliar application increased significantly pod and seed yields both in un-inoculated and seed inoculated plants with different Rhizobium phaseoli strains. Based on the result of this experiment, seed inoculation with Rhizobium phaseoli strains R147 or R136 and molybdenum foliar application at the rate of 1.5 g L-1 are recommended for obtaining the highest seed and pod yields in common bean.Download
