This study was carried out at the Faculty of Sustainable Agriculture, Rainshelter B in Sandakan campus, Universiti Malaysia Sabah from 27tt1 April 2015 until 20th October 2015 to evaluate the effects of organic fertilizers (fermented plant juice, effective microorganism) and axillary shoots (0, 3, 5) removal on the growth and yield of bird's eye chilies (Capsicum frutescens L.) planted in BRIS soil. Fertilizer set A and B was used as the control for the fertilizer factor while 0 axillary shoot was used as the control for axillary shoot factor. Three different fertilizers treatments with three different numbers of axillary shoot were each replicates for three times. There were 27 experimental units in total (3 x 3 x 3) and Randomized Complete Block Design (RCBD) was used as the experimental layout. Fertigation system was used for the fertilizer application. The parameters on vegetative growth and yield were recorded and analyzed by using two-way ANOVA at 5% significant level. Of all the parameters that had been studied, only plant height (cm) gave significant effect while the other parameters showed no significant effects. The results showed that for vegetative growth of bird's eye chilies plants, treatment S3 and H3 (fertilizer A and B with 5 axillary shoots) had the highest plant height (S3 =S3.28 cm, H3 =46.67 cm). Treatment S2 and H2 (effective microorganism with 3 axillary shoots) had the highest stem diameter which were 7.66 mm and 7.64 mm respectively. The best treatment for canopy width was S3 and H2 (Fertilizer A and B with 3 axillary shoots); S3 = 36.33 cm and 35.44 cm respectively. For the yield components of bird's eye chilies, treatment S3 and H3 (Fertilizer A and B with 5 axillary shoots) gives the highest number of fruits per plant (S3 = 25, H3 = 22), total yield per plant (S3 = 12.22 g/plant, H3 = 10.91 g/plant), and total dry weight of fruits (S3 = 2.85 g, H3 = 2.59 g). As for the fruit evaluation, S1 and H1 (fermented plant juice with 0 axillary shoot) was found to be the best treatment with highest value of weight per fruit (S1 = 0.28 g, H1 = 0.29 g), length per fruit (51 = 1.37 cm, H1 = 1.41 cm), pedicel length per fruit (S1 = 1.28 cm, Hl = 1.36 cm), and girth per fruit (S1 = 0.99 cm, Hl = 1.04 cm). Treatment S3H2 (fertilizer A and B with 3 axillary shoots) gave the highest dry weight of plant (S3 = 18.29 g, H2 = 17.84 g). Based on the chemical properties of BRIS soil, treatment S2H1 (effective microorganism with 0 axillary shoot) and S2H3 (effective microorganism with 5 axillary shoots) increased the most soil pH value (S2= 4.53, Hl and H3 = 4.47). Meanwhile, treatment S1, H2 and H3 (fermented plant juice with 3 and 5 axillary shoots) were contributing more total nitrogen to the soil (S1 =0.24 %, H2 and H3 = 0.23 %). Treatment 51 and H3 also gives the highest available P to the soil in this study (S1 = 15.24 ppm, H3 = 17.43 ppm). The highest increment of soil organic matter was contributed by treatment S3 and H2 (fertilizer A and B with 3 axillary shoots) (S3 = 1.26%, H2 = 1.30 %). Based on the study, treatment fertilizer A and B with 5 axillary shoots (S3H3) was recommended for further study because it gave the tallest plant height, highest number of fruits per plant, total yield per plant and dry weight of fruits. The second recommended treatment was fermented plant juice with 5 axillary shoots (S1H3). This is due to its ability in improving the BRIS's soil properties especially for the total nitrogen and available phosphorus in soil.
