Abstract

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