Abstract/ Executive Summary:

An experiment was accomplished at the horticultural farm, Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during to evaluate the effect neem oil and natura one for brinjal production. The experiment conducted with four treatments viz. Control (T0), Natura-one (T1), Neem oil (T2) and Neem oil+ Natura one (T3) following Randomized Complete Block Design (RCBD) with three replicates. This study was carried out to examine different characters like plant height, number of branch, infested branch, branch infestation (%), number leaves/plant, chlorophyll percentage, number of flower/plant, number of fruit/plant, infested fruit, fruit infestation (%), yield/plant (kg), yield/ha (ton) and yield increase (%) over control of brinjal. Lower infested shoot and fruits (0.2 and 0.2 plant^-1, respectively) and percentage (11.9 and 16.9, respectively) were found in T3. Highest yield (57.3 t ha^-1) and increased yield percentage over control (13.47%) were also found in T3 treatment. In view of overall performances, foliar application of neem oil and natura one has potentiality to combat the insect damage as well increase yield.

Location: At the horticultural farm, Sher-e-Bangla Agricultural University, Dhaka, Bangladesh

Start Date: 00-07-2018

End Date: 00-12-2018

Program Area: Pest Management

Commodity: Extract (plant, seed), Brinjal

Objectives:

Present investigation was designed to evaluate the neem oil and natura-one for quality brinjal production.

Methodology:

The experiment was conducted at the horticultural farm, Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during July 2018 to December 2018 to evaluate the neem oil and natura one following Randomized Complete Block Design (RCBD) with three replicates. Charki brinjal variety was used in this experiment. The experiment comprised with four treatments viz. Control (T0), Natura-one (T1), Neem oil (T2) and Neem oil+ Natura-one (T3). Natura one, a liquid biofertlizer, was collected from japan and 25 days old seedlings and neem oil were collected from local market. There were 8 seedlings transplanted in each plot and the size of each unit plot was 3.0 m × 1.0 m; line to line and plot to plot distances were 0.5 m and 1.0 m respectively while plant to plant distance was 60 cm. Manure and fertilizers were applied according to the recommendations of Bangladesh Agricultural Research Institute (BARI). Intercultural operations and watering was done as and when necessary. In case of foliar application, natura one @ 10 mlL^-1 and neem oil @ 5ml L^-1 with liquid soap were applied as treatment. Data on plant height, number of branch, infested branch no., branch infestation (%), no. of leaves/plant, chlorophyll percentage (using SPAD-5 Chlorophyll meter), no. of flower/plant, no. of fruit/plant, no. of infested fruit, fruit infestation (%), fruit length (cm), fruit diameter (mm), single fruit weight(g), yield/plant (kg), yield/ha (ton) and yield increase (%) were recorded and arranged accordingly for analysis done by MSTAT-C computer program. Differences between varieties were evaluated by Least Significance Difference Test (LSD) at 5% level of significance (Gomez and Gomez, 1984).

Achievement/Findings:

Neem oil showed effective performance to combat shoot and fruit borer and natura one (bio-fertilizer) to increase growth attributes among all the treatment. In addition, mixing of natura one and neem oil application showed superior performances to decrease infestation and increase the yield. So, it can be said that foliar spray of neem oil and natura one would be the prominent way to reduce the infestation as well as increase yield.
