PERFORMANCE OF MUNGBEAN ( (vigna radiata L.)) TO DIFFERENT BRADHYRHIZOBIUM STRAINS

Abstract

A held experiment was conducted at the Soil Science Fields of' Bangladesh Agricultural Research Institute. Joydebpur. Gazipur during the period from March to June 2007 to study the perihrmance of munghean (BARI Mung-5) to different Braclyrhi:obium strains on growth. root nodulation. yie ld and yield contributing characters, nitrogen and protein content and protein yield in mungbcan. Ihere %\erC six treatment combinations (BARI RVr-401. I3ARI RVr-402, BARI RVr-403. BARI RVr- 404. mixed culture and uninoculated control) taking with single varictN of munghan. The experiment was laid out in a randomized complete block design with thur replications. The unit plot si-ic was 4 in x 3111. A basal dose of triple super phosphate (22 kg P ha"). muriate oh' potash (42 kg K ha''). gypsum (20 kg S ha''). zinc sulphate (5 kg Zn ha'') and 1 kg I) ha" as boric acid. Alter 35 and 50 days of sowing. IC) plants were uprooted from cacti plot to study dry matter and nodulation. At man rity, yield and yield contributing characters were recorded. BrcsdI?,yrIJi:obizun inoculation increased signihieantly the number ol nodules. nodule weight. root and shoot length, seed and stover yield, and total protein content of mungbean compared to uninoculated control. Different responses were thund among the cultures. Inoculation of mtingbean seed with BARI RVr-404 strain It performed the best in respect ol nodulauon. seed and stover yield, total protein yield and other characters studied. 'Flie performance of BARI RVr-404 strain was identical to other strains on nodulation which was superior to uninoculated control. Similarly, the number of seeds seed yield and nutrient content were influenced by the /?racthvr/nzohiu,n strain where BARI RVr-404 recorded the highest yield. The results indicate that the use of Th'adhvrhizohium inoculants appears to be an effective method for successt'uI mungbean production.
