A STUDY ON MORPHOLOGICAL CHARACTERSTICS AND YIELD OF SOME BRINJAL VARIETIES

Abstract

An experiment was carried out at the Research Farm of Sher-e-Bangla Agricultural University, Dhaka during March to October, 2014 to study the morphological characteristics and yield of brinjal varieties. The experiment included eight varieties viz., Green Round, Bankim Purple Long, Debjhuri Hajari, Black Magic, Muktojhuri, Green Express, Black Boy and Tal Begun. The experiment was laid out in Randomized complete Block Design (RCBD) with three replications. The brinjal variety, Green Express showed superiority over the rest varieties in most of the morphological parameters, yield components and yield. The highest plant height (60.67 cm), number of branches plant-1 (8.33), number of leaves plant-1 (77.00) and maximum individual leaf area (200.00 cm2) were observed in variety Green Express. The same variety accumulated the maximum amount of chlorophyll (6.57 mg g-1) in its leaves and which was closely followed by Black Magic (6.10). The maximum number of flowers plant-1 (41.00) and number of fruits cluster-1 (2.23) was found in the variety Green Express which was statistically similar to Black Magic (2.18) and Bankim Purple Long (2.13) respectively. The variety Green Express provided the highest number of fruit plant-1 (15.00). The largest fruit size (185.7 cm2) was also obtained from Green Express, which was statistically similar to Tal begun (178.70 cm2). Consequently, the maximum fruit yield (47.09 t ha-1) was achieved from the variety Green Express. The second highest fruit yield (38.79 t ha-1) was recorded from Black Magic and the minimum fruit yield (12.08 t ha-1) from Tal Begun.
