Abstract

Drip irrigation is an effective method to reduce water loss during the process of cultivation, while Bacillus amyloliquefaciens is an antagonistic microorganism that can help curb disease incidence and promote plant growth. The present experiment aimed to examine the efficiency of drip irrigation combined with the use of Bacillus bacteria in promoting ‘Jinda chili’ growth. To achieve the research objective, thirty day old chili seedlings were transplanted to pots. Then irrigation was performed using one of the following four treatment: two sessions of 10 minutes irrigation at 09:30 a.m. and 03:30 p.m. (control); three sessions of 5 minutes irrigation at 09:30 a.m., 11:30 a.m., and 03:30 p.m.; two sessions of 10 minutes irrigation at 09:30 a.m. and 03:30 p.m. combined with the use of Bacillus bacteria; and three sessions of 5 minutes irrigation at 09:30 a.m., 11:30 a.m., and 03:30 p.m. combined with the use of Bacillus bacteria. The findings showed that not only could the 5 minutes irrigation treatment conserve more water than their 10 minutes counterparts by up to 23.59%, but they could also increase plant heights by 6.81%-14.00% compared to that resulting from the control method. In addition, the 10 minutes irrigation method combined with the use of Bacillus bacteria led to the highest fresh plant and root weights with the figures standing at 199.75 g and 105.00 g, respectively. However, the total yields did not differ significantly across the four treatment.
