Abstract/ Executive Summary:

A field experiment was conducted at the Regional Agricultural Research Station, Jessore and Agriculture Research Station, Rangpur during 2008-2009 to find out the performance of Tomy Green on the yield and yield attributes of BARI Brinjal-8. Five treatments viz. T₁ = Spraying of Tomy Green @ 1ml/liter, T₂= Spraying of Tomy Green @ 1.5 ml/liter, T₃ = Spraying of Tomy Green @ 2 ml/liter, T₄ = Water spray and T₅= Control (no spray) were used in the study. The yield and yield contributing characters of brinjal were significantly influenced by the Tomy Green spray. The highest yields were (43.77 t/ha at Jessore and 43.21 t/ha at Rangpur) was recorded when Tomy Green was sprayed @ 2ml/litre which was resulted in 38.95 and 39.57% higher yields compared with those of control treatment at Jessore and Rangpur, respectively. The highest benefit cost ratio was also achieved (8.65 at Jessore and 8.79 at Rangpur) when Tomy Green was sprayed @ 2 ml/liter of water in both locations. Results revealed that Tom Green sprayed @2ml/liter of water would be economically profitable for enhancing yield of Brinjal.

Keywords: Tomy Green, Yield, Yield attributes, Brinjal

Location: RARS, Jessore and ARS, Rangpur

Start Date: 25-11-2008

End Date: 20-06-2009

Program Area: Pest Management

Commodity: Brinjal

Objectives:

To find out the performance of Tomy Green and optimum dose for increasing the yield of brinjal.

Methodology:

The experiment was conducted at Agriculture Research Station, Burirhat, Rangpur and Regional Agriculture Research Station, Jessore during 2008-09 to find out the performance of Tomy Green on the yield and yield attributes of Brinjal. Five Treatments viz. T₁ = Spraying Tomy Green @ 1 ml/liter, T₂= Spraying Tomy Green @ 1.5 ml/liter, T₃ = Spraying Tomy Green @ 2 ml/liter, T₄ = Spraying of water and T₅ = Control (no spray) were used in the study. The experiment was carried out in a Randomized Complete Block design with 3 replications. The unit plot size was 3m x 3m at Rangpur and 4m x 3m at Jessore maintaining 75 cm x 60 cm plant spacing in the both locations. BARI Brinjal- 8 was used as a test crop in both locations. The experimental plots were fertilized @ 173-30-125-18 kg/ha of N, P, K and S in the form of Urea, TSP, MoP and Gypsum respectively and 10t/ha cowdung. Full dose of cowdung, TSP, Gypsum and 2/3 of Urea and ½ of MoP was applied during final land preparation. Rest of urea was applied in three equal splits i.e 1st at 15 dayes after transplanting, 2nd at fruiting and 3rd pre harvesting stage. Remaining MoP was applied into two splits i.e. 1st at 15 days after transplanting and 2nd at fruiting stage. Tomy green was sprayed six times starting from 15 days after transplanting of Brinjal seedlings at an interval of 10 days. Weeding, irrigation and other intercultural operations were done as and when required. Data on yield and yield contributing characters of Brinjal were taken. The recorded data were analyzed statistically and means were separated by DMRT.
