Using maize seedlings for baby corn production can benefit farmers who have small areas under cultivation. The objective of this study was to evaluate the possibility of using maize seedlings for the production of baby corn. The experiment was carried out in field with four treatments (direct sowing in field; transplanting seedlings 10 days after sowing (DAS); 20 DAS and 30 DAS) in randomized blocks with eight replications. Plants from seedlings 30 DAS were higher than sowing direct in field. Direct sowing in field and seedlings 30 DAS resulted in the largest stands. Sowing direct in field and transplanting seedlings at 20 and 10 DAS presented the highest number of total and commercial ears, while crops obtained from direct sowing in field yielded higher compared to the crops in which seedlings were used. Crops from maize seedlings transplanted at 10, 20 and 30 DAS reduced the period of maize plants in field by 14, 22 and 28 days, respectively, compared to maize sown directly in field. However, baby corn from direct sowing yielded 37% more than those in which seedlings were used. We concluded that the use of maize seedlings caused reduction in baby corn productivity however, it presents the advantage of reducing the permanence of the maize plants in field.
The cultivation of special corns, such as baby corn, has had a positive influence on the economy of the country. Despite its importance, there is still a need for studies aimed at increasing production and planting areas of the crop. Phytosanitary studies are of particular interest, as the cultivation of such crops is susceptible to a series of pathogens, such as Bipolaris maydis, Exserohilum turcicum, and Puccinia polysora. The use of resistant cultivars is the most effective way to prevent the occurrence of these diseases. Thus, the present study aimed to identify popcorn lines that have the potential for baby corn production and are resistant to the main leaf diseases that affect the crop. The experiment was conducted in randomized blocks with four replications of 30 lines in each area, during two planting seasons. The area was located at the Federal Institute of Espírito Santo (IFES) Campus of Alegre, situated in Rive district, Espírito Santo State, Brazil. Using the obtained data, the area under the disease progress curve was obtained. Subsequently, analysis of the joint variance of the data was conducted, and when a significant effect was found, a grouping of means test was conducted. The Mahalanobis distance for each pair of lines was also calculated, and the genetic distance matrix was used to construct a dendrogram using the UPGMA method. Considering the averages obtained for the three diseases (Southern corn leaf blight, Northern corn leaf blight, and Southern rust), lines L61, L63, L65, L683, L684, L685, L691, L694, and L695 were identified as possible donors of resistance alleles for multiple diseases. Multivariate analysis efficiently grouped the lines L61, L63, L684, L685, and L691, which are described as most resistant in the univariate analysis.
