Effect of tricoderma and organic fertilizers on vegetatif growth of black Pepper (Piper nigrum L.) under field condition

Abstract

Black pepper is a high nutrient demanding crop. However, over utilize of chemist fertilizer may give a negative impact to the environment and human health. Therefore, fertilizer use and management is crucial infortance to sustain growth and high yield. This Field experiment is carried out to study the effect of Tricoderma harzianum and liquid organic fertilizers on vegetatif growth of Black Pepper. The research method is design by Randomized Block Design (RBD) Factorial two factors. Parameters observed are the time of emergence of tendrils, spiraling length, number of tendrils, number of leaves and number of productive branches. The observed data obtained were statistically analyzed using analysis of variance and further tested by Tukey's HSD Test at 5%. The result of this research is expected to have a better effect of Tricoderma and one of the liquid organic fertilizers on vegetatif growth of black pepper in the field. Therefore, Biological Agent and organic fertilizer can be an alternative way to substitute NPK fertilizer that can reduce the chemist fertilizer utilization. In conclusion, to achieve high growth performance, organic fertilizer alone is insuffcient whilst integrated fertilization gave a signifcant increase in yield and growth of black pepper.
