Abstract/ Executive Summary:

The experiment was conducted at farmers’ fields of Bogura and Jashore during rabi season 2017-18 to evaluate the impact regarding yield, input cost and pesticide use etc on Bt brinjal production as compared to the same non-Bt counterpart under recommended IPM package. Results revealed that Bt brinjal demonstrated 90.29% reduction of fruit damage over non-Bt brinjal variety. Marketable yield increased (75.67%) over non-Bt brinjal under same IPM package. Bt brinjal offered more economic benefit (4.86) as compared to non-Bt brinjal.

Location: Bogura and Jashore

End Date: 00-00-2018

Program Area: Pest Management

Commodity: Brinjal

Objectives:

To measure the impact regarding yield, input cost and pesticide use etc on Bt brinjal as compared to the same non-Bt counterpart under recommended IPM package.

Methodology:

The experiment was conducted at farmers’ fields of Bogura and Jashore during rabi season 2016-17 following RCB design incorporating two treatments such as Treatment₁=Bt brinjal with IPM package and Treatment₂=Non-Bt isoline with IPM package with 3 replications. BARI Bt Begun-4 and its iso-line BARI begun-6 were used as test crop. Total six farmers (3 from Bogura and 3 from Jashore ) were selected from two locations. Each farmer was treated as one replication of treatment. The following IPM package was practised in the experiment: a. Raising of seedlings in polybag with the mixture of coco dust+ tricho-compost+ loamy soil +cowdung b. Grafted seedlings with BARI Brinjal-8 c. Tricho-compost application to main field d. Weeding one or two times as per necessity e. Rouging of virus infected plants f. Removal of damaged shoots and fruits by BFSB g. Using sticky (white and yellow) traps for Thrips, aphids and whitefly h. Application of bio-pesticides such as neem or microbials as needed for jassids and whitefly ( or chemicals such as Imidachloprid if neem is not sufficient to control the problems).For sucking pest such as thrips, jassids, and whitefly, three sprays were done with Azadirachtin (Bio-Neem plus 1EC) @ 1ml/L of water besides the installation of sticky traps.Data were recorded on percent shoot infestation, fruit infestation, number of sucking pests per 5 top leaves/flowers from randomly selected five plants per plot. Percent wilting and virus infection were also recorded during the study period. Marketable yield was recorded during each harvest. Marginal benefit cost ratio was also calculated. Data were analyzed by using MSTAT-c software.

Achievement/Findings:

From the results it may be concluded that Bt brinjal demonstrated higher reduction of fruit damage and higher marketable yield over non-Bt brinjal under same IPM package and provided higher benefit cost ratio. This was the second year results. The similar results were observed in previous year. So, production of Bt brinjal under standard IPM package could be suggested for brinjal production.
