Abstract

Aims: The research aimed to study the potential of sago dregs fertilizer residue in increasing the growth and yield of okra (Abelmoschus esculentus) in planting period II on marginal land. Study Design:  The research was conducted using a randomized block design with a single factor. Place and Duration of Study: The research was conducted in Field Laboratory of Faculty of Agriculture, University of Halu Oleo, Kendari, Southeast Sulawesi, Indonesia. The study was conducted for four months. Methodology: Single factor design in Randomized block design was used in the research. consists of 6 treatment levels of sago dregs fertilizer residue that have been applied in the previous planting period (planting period I), namely: without sago dregs (S0), using sago dregs 5 t ha-1 (S1), 10 t ha-1 (S2), 15 t ha-1 (S3), 20 t ha-1 (S4) and 25 t ha-1 (S5). Each treatment was placed in three groups so that there were 18 experimental units. The data was analyzed using analysis of variance and continued by Tukey Test 95% confidence level. Results: The results generally showed that the sago dregs fertilizer residual had a significant effect on the growth and yield of Abelmoschus esculentus. The effectiveness of the residual effect of sago pulp organic fertilizer is 3.39% to 25.68% on the variable plant height, 12.77% to 24.07% on the variable stem diameter, 17.72% to 32.26% on the variable number of leaves, 23.84% to 53.03% on the variable area leaves, 24.06% to 39.15% in plant dry weight variable, 20.21% to 41.61% on the variable number of fruit and 14.46% to 34.21% on the variable weight of fruit. Strongly influenced by the dose of sago pulp organic fertilizer applied in growing season I. Conclusion: Residual of sago dregs fertilizer potentially increasing of okra (Abelmoschus esculentus) growth and yield in planting period II in marginal land. The effectiveness highest was achieved in the treatment of 15 t ha-1 sago dregs organic fertilizer, for all of variables observed.
