GROWTH, YIELD AND YIELD COMPONENT OF INOCULATED CHICKPEA AND FABA BEAN PLANTS AS AFFECTED BY USING METHYLOTROPHIC BACTERIA

Abstract

Two pot experiments were performed in Giza research station, AgriculturalResearch Center (ARC) using 2 isolates of Pink-Pigmented FacultativelyMethylotrophic bacteria (PPFMs) originated from chickpea and Faba bean. Foliarapplication with PPFM isolates were conjugated with specific rhizobial inoculumand N-fertilization (15 Kg N Fed-1). Nodulation status, nitrogen fixation and growthyield and yield component were recorded. Results clearly indicated that Chickpeawas superior in its response to foliar application with PPFM.C. As it gave higherrecords of number and dry weight of nodules, dry matter and N-content of plants ascompared to Faba bean. A field experiment was also conducted in sandy loam soil atSouth EL-Tahreer province to investigate the effect of foliar application withPPFM.C strain + specific Rhizobia and N-fertilization on nodulation, growth andyield of chickpea legume plants. Results indicated that foliar application withPPFM.C in the presence of specific rhizobial inoculation scored significant increasesin economic turnover of chickpea in the range of 21-32% as compared to Nfertilizationat rate 50 Kg N Fed-1. Foliar application with 5 L Fed-1 in the presenceof 15 Kg N Fed-1 and specific rhizobial inoculation led to an increase of 518 kg fed -1productivity of seed yield , with economic turnover of 2491 L.E.
