Abstract

This study aimed to evaluate the efficacy of goat manure and coconut shell biochar on the growth and yield of red radish (Raphanus sativus L.). The field experiment was conducted at PT. Berkah Janur Kuning, Pasuruan, East Java from May to July 2025. A Randomized Block Design (RBD) with two factors was applied: goat manure doses (10, 15, 30 tons/ha) and coconut shell biochar doses (10, 15, 30 tons/ha). Observed variables included plant height, leaf count, tuber length, tuber diameter, tuber fresh weight, and tuber dry weight. ANOVA results showed a significant interaction effect on plant height (7, 14, 21, 28 DAP), leaf number (14, 21, 28 DAP), and tuber length at harvest. Single factors significantly affected leaf count (7 DAP), tuber fresh weight, and dry weight. The combination of 30 tons/ha goat manure and 30 tons/ha biochar (P3B3) yielded the optimal result, producing a fresh tuber weight of 212.41 g and dry weight of 42.48 g.
