Abstract/ Executive Summary:

An experiment was conducted to evaluate the influence of age of seedlings (30, 40, 5O and 60 days) on growth and yield of brinjal. Age of seedlings significantly Influenced the number of days to flower, plant height, foliage spread, fruit size, number of fruits per plant and yield. Although the yield was increased with increasing age of seedlings. There was no statistical difference among 40, 5O and 60 days old seedlings but they out yielded the crop from 30 days old ones.

Keywords: Brinjal, Seedling age, Growth

Location: Institute of Postgraduate Studies in Agriculture Gazipur, Bangladesh

Start Date: 00-10-1984

End Date: 00-04-1985

Program Area: Crop-Soil-Water Management

Commodity: Brinjal

Objectives:

To determine optimum age of Brinjal seedling for good yield

Methodology:

This experiment was conducted at BARI, Joydebpur, Gazipur during the period from October, 1984 to April 1985 on sandy loam soil with pi I6.2. The variety of brinjal used in this experiment was Uttara. There were four treatments of age of seedlings - 30, 40, 50 and 60 days. The treatments were replicated six times in randomized complete block design. The size of unit plot was 8.4 x 1.0 m. Cowdung @ 15 1/ha, urea @ 350 kg/ha, triple super phosphate @ 150 kg/ha and muriate of potash @ 250 mg/ha were applied in experimental plots. Cowdung and triple super phosphate and half of urea and muriate of potash were applied at the time of land preparation. The remaining urea and muriate of potash were top dressed in two equal installments on 15 January and 15 February. Seeds were sown on 1, 11, 21 and 31 October, 1984 in seed beds containing equal proportion of soil, sand and decomposed cowdung.

Achievement/Findings:

It can be concluded that the brinjal variety - Uttara may be transplanted at the age of 40 to 60 days when the seedlings would produce around 4-5 leaves.
