INFLUENCE OF VARIETY AND RHIZOBIUM INOCULANT ON THE NODULATION, GROWTH AND YIELD OF MUNCHEAN

Abstract

An experiment was conducted at Sher-e-Bangla Agricultural University, Dhaka during the period from April to July, 2007 to study the influence of variety and Rhizobium inoculant on the nodulation, growth and yield of mungbean ( Vigna radiata). The treatment consisted of three varieties of niunghean viz. V j = BAR! mung 3, V 2 = BARI mung 4, BARI mung 5 and rhizobium inoculant viz. R ( j=No inoculant, R1 = BARI Rvr 405, R 2= RENA MB I and tested in Randomized Complete Block Design (RCBD) with three replications. Results showed that variety had significant effect on growth, yield and yield components of mungbean. Compared to other varieties BARI mung 5 gave the highest number of pods plani', seeds pod', total dry weight planC 1 , 1000 seed weight, seed yield and harvest index, whereas, BARI mung 4 gave the highest number of nodules plant' , higher dry weight of nodules plant", plant height, branches plant - ', number of nodules plant". Among the two rhizobium inoculant BARI Rvr 405 showed better performance. Both the variety inoculated with BARI Rvr 405 gave significantly higher plant height, number of branches plant', number of nodules planf'and nodule dry weight plant -1 whereas, variety BARI mung 5 inoculated with BARI Rvr 405 (V 3R1 ) produced higher above ground dry weight and significantly greater yields and yield components of mungbean which was statistically similar to BARI mung 5 inoculated with 13INA MB 1 (V 3R2 ). BARI mung 4 with BARI Rvr 405 (V2 R,) and BARI mung 4 with BINA MB 1 (V 2R2 ), respecitvely.
