    GROWTH AND YIELD ATTRIBUTES OF A WHITE MAIZE GENOTYPE SAUWMOPMDT273 UNDER DIFFERENT PLANTING CONFIGURATIONS
    (DEPARTMENT OF AGRONOMY, 2020) AHAMED, SHAKIL
    A field experiment was carried out at the Agronomy Field of Sher-e-Bangla Agricultural University, during the period from July to October, 2018 to study the growth, phenology, yield attributes and yield of a white maize genotype SAUWMOPMDT273 under different planting configurations. Fifteen planting configurations viz., 40 cm × 15 cm (T 1 ), 40 cm × 20 cm (T ), 40 cm × 25 cm (T 3 ), 45 cm × 15 cm (T 4 ), 45 cm × 20 cm (T ii 5 2 ), 45 cm × 25 cm (T ), 50 cm × 15 cm (T 7 ), 50 cm × 20 cm (T 8 ), 50 cm × 25 cm (T 9 6 ), 55 cm × 15 cm (T ), 55 cm × 20 cm (T 11 ), 55 cm × 25 cm (T 12 ), 60 cm × 15 cm (T 13 10 ), 60 cm × 20 cm (T ) and 60 cm × 25 cm (T ) were considered for the present study. Data on different growth and yield attributes were recorded, processed, analyzed and found having statistically varied. Results showed that the, treatment T 15 showed significantly the maximum plant height, tassel length and leaf area at silking, grain filling and at harvest. At silking stage, the T had the highest area of an individual leaf 477.9 cm 2 , 879.3 cm 2 and 496.3 cm 15 2 as well as stem dry matter weight of 28.73 g, 21.35 g and 27.40 g plant -1 below cob-node, at cob-node and above the cob-node respectively. The treatment T showed maximum biological yield (14.64 t ha -1 ) which was identical to T 13 2 , T 4 and T in this respect. T treatment showed significantly the highest cob length (15.94 cm) and number of grains row 14 -1 (20.00), but the highest number of grains cob (231.50), 100 seed weight (29.99 g), grain weight cob -1 (59.81 g) were recorded from T 12 . T 11 had significantly the highest grain yield (4.77 t ha ) which however was not significantly higher than those of T 5 , T 13 and T (4.62-4.75 t ha -1 ). As the treatment T had sparser configuration (60×20 cm) requiring less seed rate, this configuration may be followed.
