Abstract
<p>This research study was carried out in 2009 summer growing season in Al- Baqaa area near Amman to test six increasing rates of plant populations on growth and yield of okra, variety `Clemson spineless. Treatments consisted of six planting populations (10, 20, 30, 40, 50 and 60 thousand plants/ha). Field lay out was a randomized complete block design with three replications. The results showed that increasing plant population increased yield up to 50,000 plants/ ha. Although, there was an increasing trend, okra yield under 60,000 plants/ha was not significant over that of the 50,000 plants/ha.However, plant population significantly affected plant height, number of leaves per plant, number of pods per plant and number of branches per plant but there was no significant effect<br />
of different plant populations on dry pod weight. Constant trend towards higher<br />
pod N, P and K contents by using lower planting populations were significantly<br />
noticed. At the conditions of this study, it could be concluded that, the okra yielding ability was statistically similar under the most higher plant populations of 40, 50 and 60 thousand plants/ha.</p>
