Abstract:
An experiment was conducted during May to September 2019 at Sher-e-Bangla
Agricultural University, Dhaka-1207 to evaluate the yield performance of white maize
as influenced by different levels of fertilizer under different spacing. The experiment
comprised two different factors; (1) three levels of fertilizer application viz. F
1
(Recommended doses of fertilizer (RDF), F
2
ii
(25% less than RDF) and F
3
(25% higher
than RDF); and (2) three different plant spacing viz. S
1
(60 cm × 25 cm), S
2
(50 cm ×
25 cm) and S
3
(40 cm × 25 cm). Both the fertilizer dose and spacing level along with
their interactions had significant effect on almost all vegetative and reproductive
parameters. The highest stover yield(14.8 t ha
1
) was obtained from F
2
S
3
-1
) and the lowest stover yield (5.83 t ha
(25% less than RDF and 40 cm × 25 cm) and F
3
(25%
higher than RDF and 60 cm × 25 cm) treatment combinations, respectively. The F
2
(25% less than RDF) in combination with S
2
(50 cm × 25 cm) performed the best and
obtained the highest cob length (18.45 cm), number of rows cob
-1
(13.67), number of
grains row
-1
(25.89) number of grains cob
-1
(354.54), weight of grains cob
(89.56 g),
weight of cob (118.56 g), 100- grain weight ( 35.70 g) which contributed to obtain the
highest grain yield (8.44 t ha
-1
) as well as biological yield (22.08 t ha
-1
)
