dc.description	A field experiment was conducted at Sher-e-Bangla Agricultural University Farm SAU, Dhaka during the period from October- 2020 to February-2021 in Rabi season to studying allometry and yield components of white maize to varying levels of spacing and fertilizer application. The experiment was consisted of two factors and followed split plot design with three replications. Factor A: Fertilizer application rate (4) viz, F = 50 % recommended dose of fertilizer, F 2 = 75 % recommended dose of fertilizer, F = 100 % recommended dose of fertilizer, F = 125 % recommended dose of fertilizer, Factor B: Different spacings (3) viz, S 1 4 = 50 cm × 20 cm, S 2 = 40 cm × 20 cm and S = 30 cm × 20 cm. The experimental results revealed that different fertilizer dose, spacings and their combination significantly influenced the growth, yield contributing characteristics and yield of white maize. In case of different dose of fertilizer application, the F treatment recorded the highest grain yield (11.96 t ha -1 ), stover yield (15.40 t ha -1 ), biological yield (27.36 t ha -1 ) and harvest (43.67 %) comparable to other treatments. In case of different spacing the highest grain yield (12.05 t ha -1 ), stover yield (14.77 t ha -1 ), biological yield (26.82 t ha -1 ) and harvest (44.99 %) were observed in S treatment. In case of combined effect, the F 4 S 2 3 treatment combination had the highest grain yield (12.90 t ha ) followed by F 4 S 3 (12.65 t ha -1 ) treatment combination. Components dry matter (root, stem and leaf) had positive correlations with the total dry matter accumulations. The total dry matter accumulation had strongest correlation with leaf area at 40 DAS. The exponential trend of dry matter accumulation of the treatment combinations with time largely followed that of the spacing treatments.	en_US
