Performance of single and mixed rhizobial inoculants on nodulation, dry matter and seed yield of lentil (Lens culinaris)

Abstract

Field experiments were carried out at Regional Agricultural Research Station (RARS), Ishurdi, Pabna during the rabi season of 2005-06 and 2006-07 to find out the effectiveness of Rhizobium strains for achieving higher yield of lentil, the variety BARI Masur–4. There were six treatments that were Rhizobium strains- BARI RLc-104, BARI RLc-105, BARI RLc-106, BARI RLc–107, mixed culture of the four strains, and control (no Rhizobium). The experiment was designed in randomized complete block having 4 replications of each treatment.The rhizobial inocula were peat based and used @ 1.5 kg/ha. A basal dose of P @ 22 kg/ha, K @ 42 kg/ha, S @ 20 kg/ha, and @ 5 kg Zn/ha was used for all treatments. The highest nodule number (11.7/plant in 2006 and 10.3/plant in 2007) and dry nodule weight (10.53 mg/plant in 2006 and 9.58 mg/plant in 2007) were found with mixed culture. Mixed culture produced the highest seed yield in 2006 (1.36 t/ha, 37.4% higher over uninoculated control) and in 2007, BARI RLc-104 recorded the highest seed yield (1.23 t/ha, 60.3% higher over uninoculated control). However, all the strains including mixed culture had similar seed yields over the years. DOI: http://dx.doi.org/10.3329/bjar.v39i1.20147 Bangladesh J. Agril. Res. 39(1): 105-112, March 2014

Economic evaluation of mixed cropping of Mungbean with off-season Tossa jute seed crop

“…It is due to the higher competition of moisture, space, light and nutrients with each other. The results of this reduction of relative yield in mixed cropping are in conformity with the findings of Rahman and Shamsuddin (1981) [14]. Cost and return analysis Gross return: The highest gross return was obtained from the treatment of 100%mungbean+80%jute (Tk.…”

On-Farm Application of Biofertilizer and Chemical Fertilizers on Lentil in Three Farmers’ Field of Bangladesh

“…They also reported 46% higher seed yield in lentil at Meherpur, 30% higher at Faridpur and 33% higher at Jessore due to application of Rhizobium inoculum while 72% higher at Meherpur, 59% higher at Faridpur and 75% higher at Jessore due to Rhizobium inoculum plus full doses of PKS fertilizers. Others also reported higher nodule number, nodule weight and seed yield due to Rhizobium inoculation in lentil [7][8][9][10] . The results were also in agreement with the findings of Bhuiyan et al 11 and Khanam et al 4 who worked on lentil.…”
