Effectiveness of bio-fertilizer from soybean seed mixed with sliced pineapple fruit fermentation on growth of Chinese kale yields

Abstract

The objective of this research is to determine the efficiency of bio-fertilizer from soybean seed mixed with sliced pineapple fruit fermentation on growth of Chinese kale (Brassica oleracea L.) and to study its appropriate ratio for replacing the urea fertilizer. The experiments were conducted on field to determine the growth of Chinese kale in response to bio-fertilizer as a supporting medium. The treatments were arranged in a completely randomized design with 5 treatments on 4 replications as follow. 1 plain water (0:1), treatment 2 only Urea fertilizer (25 kg/rai), treatment 3: Bio-fertilizer:water (1:100 v/v), treatment 4: Bio-fertilizer:water (1:200 v/v) and treatment 5 Bio-fertilizer:water (1:300 v/v). And then, data were investigated and recorded on growth parameters; stem height, leaf number, leaf width, petiole length and weight of Kale fresh tree. It was found that the ratio of bio-fertilizer of soybean seed mixed with sliced pineapple fruit fermentation and water and urea fertilizer had influenced on the growth parameters of Chinese kale at 21, 28, 35, 42, 49 และ 56 day after planing. Chinese kale in treatment 2 only urea fertilizer had the greatest influence on stem height, leaf number, leaf width and petiole length of kale with no significant difference (P>0,05) when compared with treatment 3 (1:100). In addition, kale at 56 day after planing in treatment 3 (1:100) was the highest of weight of fresh tree (46.6 g) with not significant difference (P>0,05) when compared with the treatment 2 (46.3 g). In this research, it can be concluded that the percentage ratio of bio-fertilizer of soybean seed mixed with sliced pineapple fruit fermentation and water as the ratio of 1:100 showed the best result as same as the result of using Urea fertilizer, and bio-fertilizer has an influence on the growth of Chinese kale
