THE EFFECT OF DIFFERENT TYPES OF ORGANIC FERTILIZERS ON GROWTH AND YIELD OF ABELMOSCHUS ESCULENTUS L. MOENCH (OKRA)

摘要

The experiment was carried out at the University Sultan Zainal Abidin (UniSZA) farm to study the effect of different types of organic fertilizers on yield performances of Albemoschus esculentus L. Moench (okra). Six different treatments (no fertilizer, NPK fertilizer, poultry manure, rat manure, goat manure and rabbit manure) were replicated three times in three beds. The experiment, arranged in Randomize Complete Block Design (RCBD), was carried out from January 2015 till May 2015. The data were collected on the growth and yield parameters including plant height (cm), leaf area (cm2), number of branch/plant, number of flower/crop, chlorophyll content, number of pods/plant, number of seeds/pod, photosynthesis rate, internal CO,, transpiration rate,weight of pods and lastly total soluble solids. From this study, the application of poultry manure increased significantly the growth and yields performances on okra compared to other types of organic fertilizers. The results indicated a significant increase in growth parameters of okra including (plant height, number of branch, leaf area, chlorophyll content, photosynthesis rate, number of flower, weight of pod. number of pod and lastly number of seeds). Poultry manure significantly increased the plantheight with 52.64 cm, while the lowest of 35.98 cm was from control plot. Okra yield of poultry manure plot had the highest number of pods with 9.67, while control plot had the lowest number of pods with 2.00. Based on the findings of the experiments, it can be concluded that application of poultry manure significant!}' increased the growth and yields performances on Albemoschus esculentus L. Moench (okra) compared to other types of organic fertilizers.
