INFLUENCE OF MORPHO-PHYSIOLOGICAL CHARACTERS AND YIELD OF OKRA THROUGH APPLICATION OF ZINC AND BORON

Abstract

The study was carried out at the Central Farm of Sher-e-Bangla Agricultural University, Dhaka during the period from April to August 2018 to study the influence of morpho-physiological characters and yield of okra (BARI Dherosh- 1). The treatments of the experiment was T ii

0 (control), T (20 kg Zn ha -1 ), T 2 (30 kg Zn ha -1 ), T 3 (10 kg B ha -1 ), T 4 (20 kg B ha -1 ), T

+ 10 kg B ha -1 ), T 6 (20 kg Zn ha -1 + 20 kg B ha -1 ), T 7 5 1 (20 kg Zn ha (30 kg Zn ha + 10 kg B ha -1 ) and T 8 (30 kg Zn ha -1 + 20 kg B ha -1 ). The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Results revealed that the highest plant height (118.30 cm) was recorded from T (30 kg Zn ha -1 + 20 kg B ha -1 ) but the highest number of leaves plant (30.06) was recorded from T 7 (30 kg Zn ha -1 + 10 kg B ha -1 ). Results also revealed that the highest leaf area index, (298.60) and SPAD value (65.73), single fruit weight (14.14 g), fruit length (15.12 cm), fruit diameter (1.96 cm), % fruit dry matter (9.26 g), number of fruits plant -1 (36.12), fresh fruit weight plant (510.70 g), fruit yield plot -1 (7.75 kg) and fruit yield ha -1 (17.22 t ha -1 -1 -1 -1 8 ) were found from T

(30 kg Zn ha -1 + 10 kg B ha -1 ) treatment, whereas the control treatment (T ) showed lowest performance for the respected parameters. From the above results it can be said that 30 kg Zn ha -1 with 10 kg B ha -1 combination may be helpful for okra cultivation in the field level to increase okra production.
