EFFECT OF PRIMING ON GROWTH, YIELD AND SEED QUALITY OF OKRA (Abelmoschus esculentus L.) VARIETIES

Abstract

The experiment was conducted into two parts. One was the field to assess the green pods (vegetable) and seed yield, and the other part was laboratory experiment for evaluating of seed quality after priming. The Research Field of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka during the period from February-June 2015 to find out the effect of seed priming on yield(green pod)) and seed yield of different okra varieties. The experiment consisted of two factors: Factor A: Three varieties of okra. V : BARI Dheros-1, V 2 : Hybrid Green Soft, V 3 1 : Hybrid Sarika and Factor B: 5 levels of seed priming with different solutions. P 0 : Control (no priming), P : priming with water (hydro priming), P 2 : priming with 3% NaCl solution, P 1 : priming with 3% KCl solution, P 4 : priming with 3% MgSO 4 3 solution. Seeds were primed at the period of 24 hours. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Data on different growth and yield contributing characters, and yield were recorded to find out the suitable variety and level of seed priming of okra. The maximum seed yield (0.633 t ha -1 ), green pod yield

(18.78 t ha -1 ) were recorded from V (Hybrid green soft). Due to seed priming treatment, maximum seed yield (0.626 t ha 2 ), green pod yield

(19.39 t ha -1 ) were recorded from that is priming with 3 % MgSO 4 solution treatment (P 4

) .In interaction effect of variety and seed priming V 2 P 4 gave the maximum seed yield (0.695 t ha -1 ) and green pod yield

(21.30 t ha -1 ) . In case of laboratory experiment the variety Hybrid green soft (V 2 ) and Priming of treatment with 3% MgSO ) showed higher germination (%) and seed vigority .so variety V and Priming treatment P 4 and interaction of V 2 P 4 4 solution (P 2 seen maximum priming for okra. -1 4
