Influence of Fertilizer Types on Growth and Yield in Okra (Abelmoschus esculentus (L.) Moench) in Southern Thailand

Abstract

Study on the influence of fertilizer sources on growth and yield of okra. Okras were planted and applied in different fertilizer types. The experiments were divided into 5 fertilizers (treatments) consisting of trt 1) okras were planted without fertilizer, trt 2) applied by chemical fertilizer, trt 3) applied by pig manure, trt 4) applied by cow manure and trt 5) applied by poultry manure. The experiment was laid out in a Randomized Complete Block Design (RCRD) with four replications, ten plants/replication at Faculty of Technology and Community Development, Thaksin University. The result of the study showed that there were significant differences between the treatments (P≤0.05) in most of the parameters assessed. The pig manure recorded the highest value in fruits/plant (65.23 fruit/plant), following by cow manure, poultry manure, chemical fertilizer and control about 54.94, 54.87, 50.62 and 17.87 fruits/plant, respectively. The yields/pod was not significant differences (P>0.05) between treatments (chemical fertilizer, Pig manure, poultry manure and cow manure) about 22.71, 22.59, 22.46 and 22.46 g/pod respectively. The fruit yield/plants were most important characteristic found that pig manure had the height yields/plant (1,473.55 g/plant), following by cow manure, chemical fertilizer poultry manure and control about 1,218.23, 1,149.58 1,122.64 and 271.98 g/plant, respectively. Chemical fertilizer was recorded the height firmness (1,110.65). Control, pig manure, cow manure and poultry manure were recorded firmness 1,009.05, 833.99, 831.86 and 812.37 g respectively. While, Okra Yellow Vain Disease and insect pests were not significant different between treatments (P>0.05).
