Abstract/ Executive Summary:

The field experiment was conducted at Regional Agricultural Research Station (RARS), Hathazari, Chattagram to find out the efficacy of integration of poultry refuse (PR) with stable bleaching powder (SBP) or CaNO₃ and Furadan 5G for the management of bacterial wilt (Ralstonia solanacearum) and root-knot nematode disease (Meloidogyne incognita) of brinjal. Soil was treated with PR @ 3 t/ha 3 weeks before transplanting, stable bleaching powder @ 20 kg/ha during final land preparation and Furadan 5G @ 20 kg/ha on the day of seedlings transplanting while CaNO₃ was used as soil drenching 10 days after seedling transplanting. Results showed that integration of poultry refuse with Furadan 5G and stable bleaching powder or CaNO₃ reduced root-knot and bacterial wilt diseases and increased plant growth as well as yield of brinjal. The most effective treatment combination was PR + stable bleaching powder + Furadan 5G with early sowing, followed by PR + CaNO₃ + Furadan 5G with early sowing for the management of bacterial wilt and root knot nematode diseases and increasing plant growth and yield of brinjal. The technology, poultry refuse+ stable bleaching powder + Furadan 5G was validated at Bangladesh Agricultural Research Institute (BARI), Gazipur, Regional Agricultural Research Station of Jessore, Hathazari and Jamalpur and also at Agricultural Research Station and farmers field at Burirhat, Rangpur and OFRD farm at Alamnagar, Rangpur. The validation trials showed that integration of poultry refuse + stable bleaching powder+ Furadan 5G in early sowing was an effective management package of bacterial wilt and root knot nematode diseases of brinjal which also offered 21.81 to 25.98% higher yield over the conventional practices.

Start Date: 00-00-2011

End Date: 00-00-2012

Program Area: Pest Management

Commodity: Brinjal

Objectives:

To find out efficacy of poultry refuses, stable bleaching powder, CaNO₃ and Furadan 5G to manage bacterial wilt and root-knot nematode of brinjal and to increase plant growth and yield of brinjal.

Methodology:

Field experiment: The experiment was conducted at the Regional Agricultural Research Station, Hathazari, Chattagram during 2011-12 to find out the effective management practices against bacterial wilt and root-knot nematode disease of brinjal. The unit plot size was 3 m ×3.75 m keeping 1m distance from plot to plot. The experiment was laid out in a randomized complete block design with three replications. Thirty days old brinjal seedlings var. BARI Begun-4 was cultivated. Ten treatments viz., T₁ = Poultry refuse @ 3 t/h + Stable bleaching powder @ 20 kg/h + early sowing (Middle of October), T₂ = Poultry refuse@ 3 t/h + CaNO₃ @ 1% solution + early sowing, T₃ = Poultry refuse@ 3 t/h + Stable bleaching powder@ 20 kg/h + Furadan 5G@ 20 kg/h + early sowing, T₄ = Poultry refuse@ 3 t/h + CaNO₃@ 1% solution + Furadan5G@ 20 kg/h + early sowing, T₅ = Control-1 (as comparison for early sowing) T₆= Poultry refuse @ 3 t/h + Stable bleaching powder @ 20 kg/h + late sowing (1^st week of December), T₇ = Poultry refuse@ 3 t/h + CaNO₃ @ 1% solution + late sowing, T₈ = Poultry refuse@ 3 t/h + Stable bleaching powder@ 20 kg/h + Furadan 5G@ 20 kg/h + late sowing, T9 = Poultry refuse@ 3 t/h + CaNO₃@ 1% solution + Furadan5G@ 20 kg/h + late sowing and T₁₀ = Control-2 (as comparison for late sowing). Partially decomposed poultry refuse @ 3 t/h was added to the soil three weeks before seedling transplanting for proper decomposition. Furadan 5G was added before seedling transplanting, Stable bleaching powder was used during final land preparation and CaNO₃ was used as soil drenching after 10 days ages of the plant. Recommended fertilizers (Urea 300 kg/ha, TSP 250 kg/ha, MP 200 kg/ha and Zypsum 100 kg/ha) were added during final land preparation as well as split at three times of different crop growth stages, weeding and irrigation were done as per recommendation of the crop. ?Validation of developed technology The validation trials using BARI Begun-8 for controlling bacterial wilt and root knot nematode diseases were conducted in the field of Plant Pathology Division, Bangladesh Agricultural Research Institute (BARI), Gazipur and also in the Regional Agricultural Research Station (RARS), Hathazari and Jamalpur during 2012-13 cropping season. The developed technology that is poultry refuse @ 3 t/ha + Stable bleaching powder @ 20 kg/h + Furadan 5G 25 kg/ha for integrated management of root knot nematode and bacterial wilt of brinjal was applied in the locations of Gazipur, Jamalpur and Hathazari where control treatment was also used for comparison. The unit plot size was approximately 1500 square meter and spacing was 60 cm x 60 cm. Similar trials with BARI Begun-4 and BARI Begun-10 were also conducted at the Regional Agricultural Research Station (RARS), Jessore and Burirhat, Rangpur, farmers’ field at Burirhat, Rangpur and OFRD farm at Alamnagar, Rangpur during 2012-13 cropping season where no control treatment was used. Poultry refuse was applied @ 5t/ha before 21 days of seedling transplanting. After application poultry refuse was properly mixed with soil and water was added frequently for complete decomposition of poultry refuse in the soil. Stable bleaching powder @ 20 kg/h was applied at the final stage of land preparation and Furadan 5G was mixed at the time of seedling transplanting. Brinjal seedlings were transplanted at the age of 35-40 days. Intercultural operations were done as per standard recommendation. Data collection and analysis: Data on different parameters viz. shoot height, shoot weight, root length, root weight and yield of brinjal were taken. During the growing period bacterial wilt incidence was recorded from seedling to maturity stage of the crop. Root knot disease severity was recorded as a gall index following 0-10 scale (Zeck, 1971) after final harvesting of brinjal. The percent data were converted into arcsine transformation values before statistical analysis. Data were analyzed statistically by using the MSTAT-C program. The treatment effects were compared by applying the least significant different (LSD) test at P=0.05 level.
