Memperbaiki Serapan Hara dengan Aplikasi Bahan Organik untuk Meningkatkan Resistensi Tanaman Cabai terhadap Virulensi Kutukebul
Nutrient balance plays a role in physiological mechanisms. Compost of tea dregs and eggshells powder have been shown to have an effect in providing nutrients but have different abilities, so synergism or antagonism between the compounds may occur. The purpose of this study was to compare the application results of compost from tea dregs and eggshell powder combination on Red-Yellow Podsolic soil to balance NPK and Ca in plant tissue and assess its relationship with plant resistance to whitefly virulence. The benefits of this research is encourage the use of tea dregs and eggshells as soil enhancers. This research was carried out at Polytechnic Hasnur’s screen house in April-October 2021 by applying compost from tea dregs and eggshell powder to Red-Yellow Podsolic soil in a cultivation of cayenne pepper of Anjasmara variety. The experiment was arranged in a complete randomized design with Tukey’s HSD test at α=5%. The results showed that the application of 120 g compost of tea dregs and 40 g eggshell powder combination increased the percentage of N, P, K, and Ca in plant tissue, thereby encouraging plant resistance to whitefly vector begomovirus virulence. There is a fairly strong and positive relationship of 63% between nutrients in plant tissues with plant resistance to virulence. The available and balanced nutrients may help plants to form elicitors optimally.
