Abstract

This study was carried out to evaluate the effect of an Empty Fruit Bunch (EFB) compost and soil texture on root characteristics and yield of purslane, (Portulaca oleracea L.). The objective of this experiments was to evaluate the effect of EFB compost on yield and roots characteristics of purslane on different soil media and to evaluate the effect of EFB compost on selected soil properties. This experiment was using completely randomized design (CRD) and it took approximately 10 weeks of planting duration that begin from soil pot preparation till harvesting. The treatments of this studies are the different rate of application of EFB compost on the different type of soil media; O t ha·1, 5 t ha·1, 10 t ha·1 and 15 t ha·1• The control of this experiment was the O t ha·1 of EFB compost application. Each treatments were replicated 4 times. Plant green biomass (leaf+stem) fresh and dry matter yield, root diameter, root surface area, root dry weight, root length, root and shoot ratio were measured after harvest. Meanwhile, soil pH, soil organic matter, total organic carbon, soil total nitrogen and soil available phosphorus were measured during before and after planting. Except for fresh and dry weight, all the parameters of roots were measured using WinRhizo 2016a. All data were then analysed using two way ANOVA at 5% level of significance and Tukey's test to analyse the mean separation. The results show that, the plants that were planted on clay soil with treatments level 15 t ha·1 shows the highest mean of plant total above ground fresh and dry matter weight, 13.51 and 124.16g, respectively. As for root parameters, there were significant interaction between soil type and treatment levels on roots surface area and root length results. With clay soil and treatment 5 t ha·1, it gives the highest results for root surf ace area (922.31mm) and for root length, clay soil with treatment 15 t ha·1 gives the highest results (9869.86mm). However, there were no significant difference on the results of plant total dry matter, diameter of plant roots and root to shoot ratio. With the highest results of 1.58g at treatment 15 t ha·1, 0.79g and 0.22g at treatment O t ha·1, respectively. For soil parameters, soil total carbon shows significant interaction on clay soil and treatment 15 t ha·1 with the highest result of 0.91 %. However, for soil total nitrogen, soil available phosphorus and soil pH showed no significant difference. With highest results, 2.08% at treatment 10 t ha·1, 0.76% at treatment 15 t ha·1 and 5.82 pH at treatment O t ha·1• The overall results of this experiments prone to show that the plants tends to strive better when applied with more amount of compost regardless of the type of soil. Most of the roots characteristics also shows a good respond toward the increasing rate of EFB application. Hence, EFB compost is recommended to be used to fix problematic soil.
