Abstract:
An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, Bangladesh, from June to December 2015 to investigate the effect of spacing and fertilizer management on the yield of transplanted Aman rice cv. BRRI dhan39.Experimental DesignThe experiment comprised:Five spacings:25 × 5 cm25 × 10 cm25 × 15 cm25 × 20 cm25 × 25 cmFour fertilizer schedules:Control (No manure and no fertilizer)Recommended dose of inorganic fertilizer (80-60-40 kg N, P₂O₅, K₂O ha⁻¹, respectively + 60 kg ha⁻¹ gypsum + 10 kg ha⁻¹ ZnSO₄)75% recommended dose of inorganic fertilizer + cow dung at 5 t ha⁻¹75% recommended dose of inorganic fertilizer + poultry manure @ 2.5 t ha⁻¹The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications.ResultsThe highest values for plant height (104.60 cm), number of total tillers hill⁻¹ (11.03), panicle length (22.25 cm), grains panicle⁻¹ (109.00), and grain yield (4.42 t ha⁻¹) were found in 25 × 15 cm spacing.Nutrient management:75% recommended dose of inorganic fertilizers + cow dung at 5 t ha⁻¹ outperformed other treatments with:Plant height: 107.50 cmTotal tillers hill⁻¹: 10.40Effective tillers hill⁻¹: 7.68Panicle length: 22.26 cmGrains panicle⁻¹: 111.70Grain yield: 4.14 t ha⁻¹Control treatment (no manures and no fertilizers) showed the lowest values for all parameters.Highest grain yield (4.57 t ha⁻¹) was obtained with 25 × 15 cm spacing + 75% recommended dose of inorganic fertilizers + cow dung at 5 t ha⁻¹.Lowest grain yield (2.50 t ha⁻¹) was found in 25 × 5 cm spacing + control (no manures and fertilizers).Therefore 25 × 15 cm spacing combined with 75% recommended dose of inorganic fertilizers + cow dung at 5 t ha⁻¹ appeared to be the most promising practice for transplant Aman rice cv. BRRI dhan39 cultivation.
