Impact of seed soaking by salicylic acid, biozyme application, and covering on okra (Abelmoschus esculentus L.)‎ germination and yield

Abstract EN

The study carried out during (April to October 2020) at two different locations in Sulaimani governorate, the first location was the Agricultural nursery in Tasluja (back to nature), and the second at the vegetable farmer in Dukan, the study determines the response of an okra variety and the effect of salicylic acid on the growth and germination of seeds and foliar application with biozyme as well as the use of temporary vegetation covering on growth, yield and seed quality.

Then the two locations were compared in quantitative and qualitative appearances of the local okra production, and their interactions on yield and its growth characteristics and the quantitative and qualitative of the local okra crop.

This study was designed as a factorial according to a randomized complete block design (R.C.B.D.) with three replicates and (54 experimental units).

An experiment was conducted to find out the effect of the vital properties of local okra seeds obtained directly in Sulaymaniyah during the season from (2020).

The seeds were soaked for 4 hours in three different concentrations (0 ppm, 75 ppm and 150 ppm) of salicylic acid with distilled water to achieve a higher germination, Biozyme foliar application at three levels (0 ml.lˉ¹, 0.75 ml.lˉ¹ and 1.5 ml.lˉ¹), and covering on okra yield quality in green shade-net house.

The results indicated that salicylic acid treatment led to significant effect on seed germination and yield.

The interaction among locations, covering, salicylic acid and biozyme foliar application, significantly (P ˂ 0.05) effected positively on pod weight (4.829 g), Yield Per Hectare (9.491 ton/ hectare), number of seeds per pod (78.467) and seed weight per pod (68.000 g).
