dc.description.abstractThis research studied the effects of utilizing Vasicular-Arbuscular Mycorrhiza (VAM), different levels of vermicast and chemical fertilizer on the physical growth, nutrient status, chlorophyll content, percentages of VAM infection and mycorhizosphere microorganism population on three different varieties of chilly, MC11, MC12 and MP. All varieties were treated with or without VAM, with three levels of vermicast (0%, 5% and 10%) and chemical fertilizer (0%, 50% and 100%). Parameters measured were plant height, total leaf number, fresh weight and yield (manual method), nutrient content; N (Kjeldahl method), P . . .• .. ,,.. . . .,. . .~., (Yellow Vanado Molybdate· method); K, Ca, Mg, Na, Zn, Fe, Cu (nitric acid); chlorophyll content (acetone solvent); percentages of VAM infection (Grid method) and microbial analysis (CFU). For chilly variety MC11, treatment with 10% vermicast and 100% chemical fertilizer resulted in the maximum mean of height increment (65.11 em), total leaf number (71), fresh weight (shoot weight: 145.76g; root weight: 80.65g), yield (186.80g) and chlorophyll content (1.83mg/mg). Utilization of 5% or 10% vermicast resulted in the highest tissue N, P, Fe and Zn content. Inoculation of VAM in combination with 5% or 10% of vermicast resulted in the highest tissue K and Mg concentration. VAM infection and mycorrhizosphere microbial population was higher with the application of 5% vermicast and 100% chemical fertilizer. For chilly variety MC12, treatment with VAM, 5% or 10% vermicast and 50% or 1 00% chemical fertilizer showed the maximum mean of height increment (55.57cm), total leaf number (103), fresh weight (shoot weight: 138.29g; root weight: 62.37g),' yield (85.78g) and chlorophyll content (1.83mg/mg). Treatment with 5% and 10% vermicast resulted in the highest tissue P, Fe, Zn, Cu content, VAM infection and mycorrhizosphere microbial population. However, inoculation with 50% chemical fertilizer resulted in the highest N, K, Ca and Na content. For chilly variety MP, treatment with 10% vermicast showed maximum mean height increment (43.7cm), total leaf number (114), fresh weight (shoot weight: 1 09.79g; root weight 47.35g) and yield (220.44g). Treatment with vermicast resulted in the highest tissue K, Mg, Na, Cu, Zn, Fe and Ca content. Utilization of vermicast and 50% chemical fertilizer significantly increased VAM infection and mycorhizosphere microbial population. Overall, utilization of 5% or 10% vermicast was shown to be capable in indusing high uptake of most plant nutrients thus resulting in good plant growth and development. Utilization of vermicast has a potential for being adopted as an alternative to the extensive use of chemical fertilizer in agriculture. It is more environmentally friendly and cost effective.en_US
