“…Thus, what limited the development in the period between V2 and V3 of the seedlings transplanted at 30 DAS possibly was the low solar radiation (due to shading) and reduced space for root growth, with It is worth mentioning that, for baby corn, this work is a pioneer and confirms other authors who evaluated the effect of the age of the seedlings on the production of other vegetables. Thus, Piovesan & Cardoso (2009) comment the influence of the age of the seedlings on production and/or quality on tomato, cucumber, squash and other fruits and vegetable crops.…”

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 seedling quality affects the plant performance in the field and proper techniques can increase the productivity of vegetables. The objective of this study was to evaluate the production of eggplant seedlings, cultivar Embu, under protected environments, containers and substrates, and its development in the field at the State University of Mato Grosso do Sul, in Aquidauana, Brazil. For seedlings production, each environment was considered an experiment, which was carried out in a completely randomized design, in split-plot scheme (containers x substrates), with eight replications. Subsequently we realized joint analysis of the experiments to compare the environments. In the field, the design was in randomized blocks using four replications. The seedlings were grown in the protected environments: greenhouse covered with polyethylene film, light diffuser, 150 micron, and nursery monofilament screen with 50% of shading (Sombrite ® ). Inside environments, polystyrene trays with 72 cells and 128 cells were tested. The containers were filled with six substrates, from the combination of cattle manure and cassava stems. In the field were distributed 24 treatments generated from combinations of three factors. In both environments, the best seedlings are formed in trays with 72 cells. For two trays the best seedlings are formed in the greenhouse. In greenhouse, the substrate with 80% cattle manure and 20% of cassava stems promoted better growth of seedlings. In the screened, beyond this substrate, seedlings produced in the substrate with 100% manure showed higher vigor. For all substrates, the best seedlings are formed in tray with 72 cells inside the greenhouse. In the field the combination, "greenhouse + 72 cell tray + 80% manure and 20% cassava stems" was where the plants had better growth and productivity.

Objetivando estudar o comportamento do Melão Caipira cultivado em bandejas com substrato comercial a céu aberto e 50 % de sombreamento, um ensaio foi realizado no delineamento experimental blocos casualizados com 4 repetições e os tratamentos configurados num fatorial 2x4x2, (tipo de bandeja: 72 e 128 células; estádio de crescimento: uma a quatro folhas verdadeiras; ambiente: céu aberto e cultivo protegido). Os resultados apontaram que altura e comprimento da raiz variam, independentemente do tipo de bandeja e ambiente, onde plântulas de ambiente fechado e bandejas de 72 células são maiores. Tal comportamento se repete na aferição de estádio de crescimento e ambiente, onde as plântulas obtidas em bandejas de 72 células apresentaram maior massa fresca da parte aérea. Todavia, bandejas com 72 células e ambiente protegido favorecem o aumento da relação parte aérea/raiz. Conclui-se, pois, que bandejas com 72 células e o ambiente protegido evidenciam mais o crescimento da parte aérea, aumentando a relação entre estes segmentos. Assim, é possível realizar o transplante até o estádio de quarta folha com o uso de bandejas de 72 células; na quarta folha em bandejas de 128 células a céu aberto e, na terceira, em cultivo protegido.
