“…This might be due to the reason that the trait might be under the genetic control and has low influence on variation in environmental condition [ 43 ] and similar finding has also been reported by Dhakal et al. [ 8 ] in three-way cross hybrid maize. A significant difference between the genotypes and nonsignificant difference in Genotype × Environment interaction was also reported by Tripathi et al.…”

“…Wider the gap between tasseling and silking, higher the chances of infertility, unfilled kernels in cob and ultimately reduction in grain yield. The major reason of same genotype having longer silking duration in winter has been attributed to low temperature and sunlight, as silking is highly sensitive to cold stress during crop growth [ 8 ].…”

“…The mentioned cob characteristics are the yield attributing traits and are found to be positively correlated with yield i.e. increase in any of the cob characteristics increases the yield [ 7 , 8 ].…”

“…After harvesting all the ears from each plot was collected, ear count was taken and later converted in hectare ( Equation 1 ) as suggested by Badu-Apraku et al. [ 12 ] which was also followed by others [ 7 , 8 , 13 , 14 , 15 , 16 ] in maize breeding program. Ears from tagged plants were taken and used for recording cob characteristics like Cob length (CL), Cob diameter (CD), Number of grains per row (NOGPR), and Number of rows per cob (NORPC).…”

“…The study of genotypes in different seasons is desired as a genotype suitable for summer cultivation may not be suitable for winter and vice versa and some can perform optimally with stable production in both seasons [ 3 , 4 , 6 ]. The variation in yield and yield attributing traits of maize has also been associated with variation in agro-climatic conditions [ 7 , 8 ] and cropping domain [ 2 , 5 ].…”

Zinc deficiency affects one third of the population worldwide, and vitamin A deficiency is a prevalent public health issue in Sub-Saharan Africa and South-Asia, including Nepal. Crop biofortification is the sustainable solution to these health—related problems, thus we conducted two different field trials in an alpha lattice design to identify zinc and provitamin A biofortified maize genotypes consistent and competitive in performance over the contrasting seasons (Season 1: 18 February to 6 July 2020 and Season 2: 31 August to 1 February 2020/21). In our study, the performance of introduced maize genotypes (zinc—15 and provitamin A biofortified—24) were compared with that of the local check, focusing on the overall agro-morphology, yield attributes, yield, and kernel zinc and total carotenoid content. Zinc and total carotenoid in the tested genotypes were found in the range between 14.2 and 24.8 mg kg−1 and between 1.8 and 3.6 mg 100 g−1. Genotypes A1831-8 from zinc and EEPVAH-46 from provitamin A biofortified maize trial recorded kernel zinc and total carotenoid as high as 52.3, and 79.5%, respectively, compared to the local check (DMH849). The provitamin A genotypes EEPVAH-46 and EEPVAH-51 (total carotenoid: 3.6 and 3.3 mg 100 g−1), and zinc biofortified genotypes A1847-10 and A1803-42 (20.4 and 22.4 mg kg−1 zinc) were identified as superior genotypes based on their yield consistency over the environments and higher provitamin A and zinc content compared to the check. In addition, farmers can explore August sowing to harvest green cobs during December-January to boost up the emerging green cob business.
