Growth response and changes of soil chemical properties with application of vermichar in bell pepper production
Abstract
This study was conducted to evaluate the efficacy of vermichar as organic soil amendment on bell pepper and its effect on soil chemical properties. The study was laid out using the Randomized Complete Block (RCB) design to test the following treatments: T1-Control, T2-90-60-30 kg NPK, T3-90-60-30 kg NPK plus 5 bags vermichar, T4-90-60-30 kg NPK plus 10 bags vermichar, T5-90-60-30 NPK plus 15 bags vermichar and T6-10 bags vermichar. The experiment was established at the College of Agriculture, Isabela State University, Echague, Isabela from November 2023 to March 2024. Result of the study shows that the application of vermichar improves soil pH, soil nitrogen (0.01-0.22%), soil P (160.14-519.24 ppm), K (214-310ppm), Co (2.71-6.40ppm), Zn (2.89-18.93ppm). In addition, no significant effect was also observed in terms of iron and manganese when soil was applied with 5 10 15 bags of vermichar. Growth of bell pepper was also affected by the increased rate of vermichar application due to the inherent nutrient present in the material. In terms of crop productivity, bell pepper applied with 10 to 15 bags plus the addition of recommended amount of NPK recorded the highest number of fruit and yield resulting also to have the highest return of investment compared to control plants.
