Agriculture nowadays is an important sector of Malaysia especially in production of chilies for domestic and international market. Thus, application of biological control is necessary to produce a good yield in especially to organic farmers on eco-friendly method for improvement. Trichoderma sp. is a soil fungus which showed as biocontrol.
Thus, the objectives of the study was to determine the efficacy of Tricompost as biofertilizer as maintenance for the chilli plant growth and productivity in the net house
at Agropark. The treatment were: T1 = 100 g Tricompost, T2 = 10 g chemical, T3 = control, T4 = 50 g Tricompost + 5 g chemical, T5 =15 g chemical and T6 = 150 Tricompost. A total of 53 chilli seedlings were planted in polybags contained soils. Plant growth were determine based of plant length, diameter of stem and number of leaves. The result showed that T6 = 150 Tricompost effective for highest growth of chili stem diameter and increase number of leaves while T5 =15 g chemical result highest length of chili growth among treatments. Using chemical fertilizer can increase the yield
nevertheless chemical residues caused environment pollution, to overcome this problem to use biofertilizer. This project will be determine either the Tricompost have the efficacy for maintenance chilli plant growth or vice versa.
