Abstract
A field experiment was conducted at the Horticulture Farm of Sher-e-Bangla Agricultural University, Dhaka, from November 2024 to April 2025, to evaluate the influence of probiotic liquid manure (PLM) as a supplement to inorganic fertilizer on the growth and yield of radish (Raphanus sativus L.). The experiment comprised six treatments: T0 (control, no fertilizer), T1 (100% recommended NPK), T2 (75% NPK + PLM), T3 (50% NPK + PLM), T4 (25% NPK + PLM), and T5 (100% organic: PLM only). The single-factor experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. Significant differences were observed among treatments for all growth and yield parameters. Among the treatments, T2 (75% NPK + PLM) showed superior performance, producing the highest root length (26.5 cm), root diameter (42.1 mm), leaf number (16.2), single root weight (659.7 g), SPAD value (62.3), and maximum yield per plot (43.5 kg) corresponding to yield per hectare (210.2 t/ha). In contrast, the control (T0) exhibited the lowest values for most parameters, including yield (101.2 t/ha). The study concludes that supplementing 75% of recommended NPK with probiotic liquid manure significantly enhances radish growth and yield, indicating its potential as an eco-friendly and effective alternative in integrated nutrient management.
