The experiment was conducted to screen the suitable maize hybrids available in Bangladesh on the basis of their vegetative characteristics. The mean and range were calculated by using MSTATC software program. Highly significant variations among 50 maize genotypes understudied. The range of cob height was recorded from 53 to 90 cm with a mean value of 74.29 cm. The highest cob height (90 cm) was recorded in genotype BM-5, and the lowest cob height (53 cm) was observed in the genotype PAC-999. Plant height varied significantly in different maize genotypes. It ranged from 156.67 cm to 298.90 cm, with a mean value of 210.34 cm. The lowest (156.67 cm) plant height was recorded in genotype Badsha, and the highest (238.90 cm) plant height was observed in genotype NZ-510. The average number of leaves per plant was recorded at 12.82, and it ranged from 10.53 to 14.63. The maximum (14.63) number of leaves per plant was recorded in the genotype BHM-6, and the minimum (10.53) number of leaves per plant was observed in maize genotype PAC-999. The average leaf length was recorded at 87.04, and it ranged from 65.33 to 102.10. The longest (102.10) leaf length was found in genotype BM-5, and the shortest (65.33) leaf length was observed in genotype Badsha. The average leaf breadth was recorded at around 8.81, and it ranged from 5.80 cm to 10.37 cm. The broadest (10.37 cm) leaf was recorded in genotype NZ-003, and the narrowest (5.80 cm) leaf was observed in the genotype of Badsha, which was followed by Kbd-222 (7.56 cm). The lowest plant height (156.67 cm) was recorded in genotype Badsha, and the maximum number of the leaf (14.63) per plant was recorded in the genotype BHM-6; these two hybrids can be cultivated as a commercial variety.

The experiment was conducted to screen some maize varieties available in Bangladesh on the basis of their reproductive characteristics. Mean data were used to statistical analyze like analysis of variance, mean, range were calculated by using MSTATC software program. Significant variations among 50 maize genotypes in terms of all the yield contributing characters were found in this study. The lowest (24) days to 50% tasselling was found from the genotype 25KSS and VA-786, while the minimum (54) days to 50% silking was observed in the genotype PAC-984. The longest (21cm) cob was observed in the genotype VA-786, and the highest (17.07cm) cob diameter was recorded in the genotype GP-838.The highest (16.61) row per cob was recorded in the genotype NZ-001, and the highest (40.40) number of grains per row was recorded in the genotype PAC-399. The highest100grain weight (383.33g), was recorded in the genotype 25KSS, while the lowest (153.3g) was observed in the genotype of Uttaran-2. Statistically, significant variation was recorded for days to maturity in different maize genotypes. The highest (116) days to maturity were found in the genotype Elite, while the lowest days to maturity (107.3) were found in the genotype BHM-3. Grain yield (t ha-1) varied significantly in maize genotypes under the study. The average grain yield was recorded at around 6.14(t ha-1), and it ranged from 2.30 to 8.17. The highest grain yield (8.17 t ha-1) was recorded in genotype BHM-9, which was followed by PAC-984 (7.90t ha-1) and Pacific-98 (7.90t ha-1). Therefore, this experiment suggests that these three hybrids– namely, BHM-9, PAC-984, and Pacific-98 have a high potential to produce more yield and are suitable for commercial cultivation in Bangladesh.

The present study was undertaken to estimate the profitability and resource use efficiency under different farm size groups of maize production. In total, 65 farmers (30 small, 30 medium and 5 large) were randomly selected from five villages of Bogra district. Both tabular and statistical analyses were applied in this study. Cost and return analysis reveal that maize is a profitable crop for all categories of farmers. On an average per hectare total cost of maize production was estimated at Tk 46278 for all farmers and Tk 41263, 53554 and 48715 for small, medium and large farmers, respectively. Again, gross margins from maize production were estimated at Tk 67592, 64694 and 74089 for small, medium and large farmers, respectively. However, net returns for the farm size groups of small, medium and large were calculated at Tk 57823, 53895 and 64138 per hectare, respectively. BCR was the highest (2.40) for the small farmers followed by medium (2.01) and large (2.32) farmers, respectively. Cobb-Douglas production function analysis indicated that out of nine variables, the effects of using seed, manure, fertilizer, irrigation and insecticide had significant impact on gross return from maize production for all farmers. Efficiency analysis indicated that most of the farmers inefficiently used their inputs. The findings of the study revealed that large farmers earned higher profit than those of small and medium farmers. The study also indicated some problems and constraints of maize cultivation and suggested some recommendations to improve maize production with a view to increasing the household income and employment opportunities of the farmers.
