Abstract/ Executive Summary:

Yield potential of eggplant is an important determinant for selecting crop for effective and economic cultivation. An experiment was conducted in Hajee Mohammad Danesh Science and Technology University campus to investigate the yield potential of some eggplant varieties using plant growth regulator. Seven varieties of eggplant viz., BARIBegun-1, BARIBegun-2, BARIBegun-4, BARIBegun-5, Bismillah, BARIBegun-6, and Islampuri were used for test crop and Naphthalic acetic acid (NAA) 100 ppm was used as plant growth regulator. Eggplant variety BARIBegun-5 showed the highest plant height (31.0 cm) at vegetative stages among the tested varieties. The mean Leaf number (32.0) was also higher in BARIBegun-5 in comparison to others. Leaf surface area which is important to photosynthic activities in eggplant was also significantly greater in BARIBegun-2 cv. Tarapuri, compare to other varieties. Yield potent was significantly higher in BARIBegun-5 followed by BARIBegun-5. The lowest yield was performed by BARIBegun-6. There is no significant effect of plant growth regulator NAA for growth and yield of eggplant. From this study it is inferred that eggplant cv. BARIBegun-2 cv. Tarapuri might have best yield potential in the study area but it needs further extensive study using different plant growth regulators.

Keywords: Eggplant, Pant growth regulator, Yield, Leaf surface area

Location: The experimental farm of Hajee Mohammad Danesh Science and Technology University, Dinajpur

Start Date: 00-00-2009

End Date: 00-00-2009

Program Area: Crop-Soil-Water Management

Commodity: Brinjal

Objectives:

1. To provide a suitable technology for a variety or varieties of eggplants with high yield potential for the Northwest region of Bangladesh
2. To know the adaptive responses of some eggplants varieties under different plant growth regulators
3. To recommend a suitable variety for the farmers and peoples of the Northwest region of Bangladesh for food security

Methodology:

An field experiment was conducted at the experimental farm of Hajee Mohammad Danesh Science and Technology University, Dinajpur in 2009. A randomized completely block design (RCBD) with three replications was followed for the purpose. Treatment arrays are as: plant growth regulators (PGR): three levels including control W₁; water spray with no PGR, W₂; IAA 100 ppm and eggplant varieties: seven different varieties are-T₁- BARIBegun-1 cv. Uttara, T₂- BARIBegun-2 cv. Tarapuri, T₃- BARIBegun-4 cv. Kazla, T₄- BARIBegun-4 cv. Nayantara, T₅- Bismillah, T₆- BARIBegun-6, and T₇- Islampuri. Seeds of some eggplants varieties were collected from different parts of Bangladesh including high yielding varieties from Bangladesh Agricultural Research Institute, Gazipur and some varieties from local market. Of them, seeds of five different varieties were used for plant culturing purposes. The parameters were measured viz., leaf surface area, leaf number, plant height, total fruit weight per plant for each variety. The data collected on different parameters under the experiment were statistically analyzed to obtain the level of significance using MSTAT-C computer programme developed by Russel (1986). The treatments means were compared by Duncan’s Multiple Range Test (DMRT).

Achievement/Findings:

In conclusion the present studies indicated that growth and yield of different varieties was not markedly influenced due to plant growth regulator-NAA. Among the seven varieties of eggplant, BARIBegun-2 cv. Tarapuri showed the best yield potential in the study area. Therefore, it is suggested that the BARIBegun-2 cv. Tarapuri is recommended for the study area for getting better yield. But it also infers that more intensive research is needed considering other factors and using different PGRs.
