Abstract
This study was conducted on twenty of okra lines (treatments) at the Thaksin University
in two farming systems (conventional and organic cultivations). The experiments of
conventional and organic cultivations were carried out in a Randomized complete
block design (RCBD) with four replications to evaluate the yield, yield components
and genetic variations. The results showed significant variability (p≤0.05) in the okra
lines for fresh important traits of yield; marketable fruits.plant-1
, fruit yields.plant-1
,
seeds.fruit-1
, 100 seed weight, 1000 seed weight and harvest index. The number of
marketable fruits.plant-1 of KN-OYV-02 line showed the number of marketable fruits
yield approximately 60.85 and 51.91 fruits.plant-1 under the conventional and organic
farming systems, respectively. The lowest of marketable fruits.plant-1 were investigated
in the OP (Open Pollination) line (30.58 and 26.74 fruits.plant-1 under the conventional
and organic farming systems, respectively). KN-OYV-02 line produced the highest
yield of two farming system (1,168.37 g.plant-1
). The OP line produced the lowest yield
under the organic farming system (505.16 g.plant-1
). There were significant interactions
between the cropping system and lines for the two system plantations. So, the results
indicated that the KN-OYV-02 line showed the highest potential for okra breeding and
production in both systems.
