Abstract/ Executive Summary:

The experiment was conducted at the sick plot, Pulses Research Centre, Ishurdi, Pabna, Bangladesh during two consecutive years of 2011-12 and 2012-13 to screen out the effective BARI Rhizobium Biofertilizers against foot and root rot of lentil. Seven BARI Rhizobium strains viz. BARI LE 715, BARI Rlc 103, BARI Rlc 140, BARI Rlc 107, BARI Rlc 105, BARI Rlc 138 and BARI Rlc 101 were used as treatments. In 2011-12, foot and root rot incidence ranged from 9.66-29.95%, while the lowest incidence was recorded in BARI LE 715 which was followed by BARI RLC 140, BARI RLC 107 and BARI RLC 138; and the highest incidence was recorded in untreated control. BARI LE 715 gave the highest plant survival (90.34%) and control treatment gave the lowest plant survival (70.05%). BARI LE 715 treated plots reduced maximum foot and root rot incidence (67.75%) over untreated control. Similar trends of the results were observed in 2012-13. The highest yield 2153 and 2016 kg/ha was obtained from BARI LE 715 in 2011-12 and 2012-13, respectively, and the lowest of these parameters were obtained from untreated control for both the years.

Commodity: Diseases, Lentil

Objectives:

To screen out the effective BARI Rhizobium Biofertilizer against foot and root rot and yield of lentil.

Methodology:

The experiment was conducted in the sick plot at Pulses Research Centre, Bangladesh Agricultural Research Institute (BARI), Ishurdi, Pabna, Bangladesh during two consecutive years of 2011-12 and 2012-13. The experimental plot was prepared with five ploughings and cross ploughings followed by laddering to break the clods as well as level the soil. The weeds and stubbles of previous crops were collected and removed from the soil. No any chemical fertilizers were applied. The experiment was carried out following Randomized Complete Block Design with three replications. The unit plot size was 1.6 m x 1.5 m and plant spacing was 30 cm with continuous sowing for the experiment. Seven BARI Rhizobium Biofertilizer viz. BARI LE 715, BARI Rlc 103, BARI Rlc 140, BARI Rlc 107, BARI Rlc 105, BARI Rlc 138 and BARI Rlc 101 were used as treatments. BARImasur -1 was used in this experiment. Seeds were initially moistened with molasses at the rate of 40 g per kg seed and then the seeds were thoroughly mixed with peat based BARI Rhizobium Biofertilizer @ 40 g per kg seed before sowing, where biofertilzer contained 108 Rhizobial cells/mg (Somasegaran and Hoben, 1994). The inoculant-coated seeds were sown at the afternoon on November 8, 2011 and November 16, 2012, respectively, and furrow was filled up just after seed sowing. Intercultural operations were done as per needed and to maintain the normal hygienic condition of crop in the field. During the growing period the plots were inspected regularly to record the incidence of foot and root rot disease from seedling to maturity stage of the crop. Dead plants were counted and removed from the field. Disease plant parts were collected and brought into the laboratory for identifying foot and root rot causal pathogens. The crop was harvested on March 4, 2012 and March 12, 2013, respectively. Data were recorded on foot and root rot, plant survival, plant height, number of pods/plant, number of seeds/plant, weight of seeds/plant and yield (kg/ha). The incidence of foot and root rot of lentil was recorded at every alternate day. The incidence of foot and root rot of chickpea was calculated by a formula.

The recorded data were analyzed statistically to find out the level of significance and the variations among the respective data were compared following Duncan’s New Multiple Range Test (DMRT) according to Gomez and Gomez (1984).

Achievement/Findings:

From the above study, it may be concluded that seed treatment with BARI LE 715 @ 40 g/kg seeds showed better performance followed by BARI RLC 107, BARI RLC 140 and BARI RLC 138 in respect of foot and root rot control and increase yield of lentil.
