Effect of different levels of organic fertilizer on growth, yield and economic benefits of radish (Raphanus sativus L.)

Abstract

An experiment was carried out at A-to-Z Agro Farm Bagatipara, Natore, Bangladesh from October to December 2020, to study the growth, yield and economic benefits of radish (Raphanus sativus L, V: Rocky 45) as influenced by different levels of organic fertilizer (Kazi organic fertilizer). The experiment was laid out in a Randomized Complete Block Design (RCBD) comprising four treatments with three replications. The treatment combinations were T0 (no organic fertilizer), T1 (organic fertilizer 5 t ha-1), T2 (organic fertilizer 10 t ha-1), T3 (organic fertilizer 15 t ha-1), respectively. Data were recorded from different stages of plant growth on plant height at different days after sowing, number of leaves per plant, leaf length, leaf breadth, root length, root diameter, fresh weight of root per plant, gross yield and marketable yield. All the recorded parameters were statistically significant among the treatments. The tallest plant (40.92 cm) was recorded from T3 (organic fertilizer 15 t ha-1), whereas the shortest plant height plant (25.84 cm) was obtained from the control T0 (no organic fertilizer). Highest number of leaves (16.56), leaf length (33.02 cm), leaf breadth ((8.74 cm), root length (19.33 cm), root diameter (3.50 cm), fresh weight of root per plant (129.89 g), gross yield (36.37 t ha-1), marketable yield (36.37 t ha-1) and also the highest benefit cost ratio (2.67) was found in treatment T3 (organic fertilizer 15 t ha-1) whereas lowest data recorded from control T0 (no organic fertilizer). Results conclude that application of organic fertilizer 15 t ha-1 for radish cultivation gave better growth, yield and economic benefits.
