Effect of genotype on proximate composition and biological yield of maize (Zea mays L.)
Abstract
An experiment was conducted to study the proximate composition of five released maize varieties (Zea mays L.) of Bangladesh Agricultural Research Institute (BARI), which was popularly growing in Bangladesh namely BHM-5, BHM-8, BHM-13, BHM-15, and Barnali. There was none a single variety performed best in all nutrient parameters. Among these maize varieties, the highest grain weight of 100 seeds, and yield was found in BHM-15 (32.84g and 12.6 ton/ha). In the case of proximate analysis, the highest protein, ash, and fat content was recorded from BHM-15 (13.11%, 2.33%, and 5.44%), the highest carbohydrate content was recorded from BHM-13 (82.40%), and the highest amount of fiber was recorded from BHM-5 (2.07%). On the other hand, the lowest amount of carbohydrate and protein was recorded from BHM-15 (77.67%) and BHM-8 (10.96%), respectively. BHM-13 contained the lowest amount of fiber (1.24%) and fat (4.27%). Barnali and BHM-15 showed better performance for most of the minerals. The findings concluded that the different genotypes of maize differ substantially in their chemical and mineral compositions.
