Abstract/ Executive Summary:

The experiment was conducted against wilt of chickpea at RARS, Jessore during Rabi season of 2009-10 and 2010-11 to reduce the use of chemical fungicide to against wilt disease and increase yield of chickpea. Pre-sowing soil treatment with Poultry litter (5 t/ha) with proper seed treatment by Provax (2 gm/kg seed) reduced wilt incidence with 34.36% in 2009-10 and 56.81% in 2010-11. Neem oil cake (100 kg/ha) in combination with Provax also decreased wilt incidence over control. Germination was highest in Provax treated plot in both the year (97.18% in 2009-10 & 96.11% in 2010-11), where Poultry litter + Provax integrated treatment also performed good in case of germination (94.62% in 2009-10 and 95.20% in 2010-11). Yield increased over control was also highest in Poultry litter + Provax combined plot (65.09% in 2009-10 and 77.15% in 2010-11). Among the two biocontrol agents, the performance of Trichoderma harzianum was better than Trichoderma viridi.

Location: Experimental Field of RARS, BARI, Jessore

Start Date: 00-00-2009

End Date: 00-00-2011

Program Area: Pest Management

Commodity: IPM

Objectives:

To develop an integrated management practice to reduce disease by reducing the use of chemical fungicides and increase yield of chickpea.

Methodology:

This experiment was conducted at RARS, Jessore during Rabi season in both the year 2009-10 and 2010-11. It was a RCB design with 3 replications. The plot size was 3.2 m x 2.0 m in 2009-10 and 3.2 m x 3.0 m for the year 2010-11 with row to row distance 40 cm and replication to replication distance 1 m. BARI Chickpea 1 was used as an experimental material. Ten treatments were used in this experiment viz. T₁ = Trichoderma harzianum (Th), T₂ = Provax (P), T₃ = Poultry Litter (PL), T₄ = Mustard Oil Cake (MOC), T₅ = Neem Oil Cake (NOC), T₆ = PL + P, T7 = MOC + P, T₈ = NOC + P, T₉ = Trichoderma viridi (Tv) and T₁₀ = Control. Provax (Carboxin + Thiram) @ 2 gm/kg seed was used as seed treating material. Three organic matter viz. Poultry litter @ 5 ton/ha, Mustard oil cake @ 1 ton/ha, Neem oil cake @ 300 kg/ha were mixed with the experimental plot 21 days before sowing the seed as it could decompose properly. Two bio-control agents viz. Trichoderma harzianum and T. viridi were grown on petridishes on Potato Dextrose Agar media, and scrub finally mixed with the seed before sowing. Number of germinated seeds was counted 14 days after germination. The mortality symptoms were observed very closely and recorded at every alternate day from emergence of seedling to maturity stage. Data on yield was recorded after necessary sun drying of seeds. The recorded data were statistically analyzed by least significance difference (LSD) for comparisons among the treatments.

Achievement/Findings:

It may be concluded that Poultry litter applied as soil amendment (21 days before seed sowing) and Provax (2 gm/kg seed) used as seed protectant (at the time of seed sowing) gave best result in case of reducing wilt disease and increasing yield of chickpea.
