The effect of planting media and application of PGPR on growth and yield of Okra (Abelmoschus esculentus L.)

Planting Okra on polybag can be done by focusing on planting media used. The addition of organic material on the planting media was able to supply nutrients for plants. Besides that, with the addition of PGPR which is a group of beneficial bacteria has potential to stimulate the growth of plants and improve yields. The purpose of this research was to determine the effect and get the best combination of PGPR interval application with the use of planting media on the growth and yield of okra. This research used a randomized completely block design (RCBD) with PGPR interval as the first factor, consisting of 5 levels and planting media as the second factor consisting of 2 levels, so overall there were 10 treatment combinations with 3 replications. The results showed that there was no interaction between the treatment of planting media and PGPR. Separately, PGPR treatment gave no significant difference to number of fruit. While media two's treatment (M2) consisting of soil, goat manure and charcoal husk with a volume ratio 1 : 1 : 1 gave the highest result on observation of plant height, number of leaves, leaf area, leaf area index, number of fruit, fruit length, total fresh weight, and also total dry weight. The result number of fruit in this research was 23.69 fruit/plant and 473,8 g /plant for fresh weight of fruit.
