RESUMO - O objetivo deste estudo foi avaliar as características morfoagronômicas do híbrido simples de milho em função da aplicação de diferentes intensidades de desfolha artificial, realizadas no estádio R1 de desenvolvimento. O experimento foi conduzido na área experimental do Instituto Federal Goiano,em Morrinhos-GO, na safra 2015/2016. Foi aplicado o delineamento de blocos completamente casualizados, com oito tratamentos e quatro repetições, sendo eles: remoção de uma folha acima e uma abaixo da espiga; remoção de duas folhas acima e abaixo da espiga; remoção de três folhas acima e abaixo da espiga; remoção de todas as folhas da planta; remoção de todas as folhas acima da espiga; remoção de todas as folhas abaixo da espiga; remoção da folha da espiga; e testemunha sem desfolha. Os caracteres avaliados foram: estande de plantas, número de plantas acamadas, prolificidade, densidade de colmo, comprimento e diâmetro de espiga, comprimento de grão, massa de mil grãos, massa de grãos espiga-1 e produtividade. Os dados foram submetidos à análise de variância pelo teste F a 5% de probabilidade, observando que todas as variáveis avaliadas foram influenciadas quanto aos efeitos dos tratamentos empregados. O enchimento dos grãos esteve intimamente relacionado à fotossíntese. Sem as folhas, esta fase ficou plenamente comprometida.Palavras-chave: Zea mays, fotoassimilados, translocação, índice de área foliar, rendimento. MORPHOAGRONOMIC CHARACTERISTICS OF MAIZE AS A FUNCTION OF DIFFERENT LEVELS OF ARTIFICIAL DEFOLIATION  ABSTRACT - The objective of this study was to evaluate of morphoagronomic characteristics of simple hybrids of maize, depending on the application of different intensities of artificial defoliation, carried out in R1, when the style-stigma were fertilized. The experiment was conducted in an experimental area of the Instituto Federal Goiano, Campus Morrinhos, State of Goiás, Brazil, during the agricultural year 2015/2016. We applied the design of completely randomized block with eight treatments, in four replications: removal of a leaf above and one below the ear; removal of two leaves above and below the ear; removal of three leaves above and below the ear; removal of all leaves of the plant; removal of all leaves above the ear; removal of all leaves below the ear; removal of the leaf of the ear; and control without defoliation. The traits evaluated were stand of plants, number of plant lodging, prolificacy, density, length and diameter of the cob, length of a grain, weight of a thousand grains, grain mass cob-1 and productivity. The data obtained were subjected to analysis of variance by F test at 5% probability, noting that all variables were influenced as to the effects of the treatments used. The filling of grains is closely related to photosynthesis. Without the leaves, this phase was fully damaged.Keywords: Zea mays L., photoassimilates, translocation, leaf area index, yield.

Effect Of Light

Anthocyanin production in roots and shoots of Zea mays L. seedlings was higher in blue than in red light and was very low in far red light. Under dichromatic irradiation, a phytochrome mediation of a blue-dependent photoreaction was evident. Pretreatments with both white and blue light allowed increased anthocyanin production under subsequent inductive conditions, as did occurs in treatments with continuous blue, red, far red, or white light. It is suggested that the effect of light pretreatments on phytochrome-controlled anthocyanin formation may differ from that controlled by the combination of cryptochrome and phytochrome.

Objectifs : Cette étude se veut de produire et de déterminer la valeur fertilisante du vermicompost, et mesurer les effets de ce vermicompost sur la croissance et le rendement du maïs. Méthodologie et résultats : Les travaux ont d’abord consisté à élaborer un compost d’ordures ménagères puis son vermicompost associé par inoculation du ver de terre Eudrilus eugeniae (Kinb.), et ensuite à évaluer leurs effets sur la production du maïs à travers un essai conduit en milieu naturel au sein de l’Université Jean Lorougnon Guedé Daloa. Les traitements sont composés d’un témoin constitué d’un sol de jachère, d’un compost d’ordures ménagères associées aux balles de riz et du vermicompost correspondant. Les résultats ont révélé que le vermicompost a les teneurs les plus importantes en N, P et K, mais les plus faibles concentrations en Cu, Zn et Pb. Les plants de maïs croissent mieux sur le vermicompost par comparaison au compost et au témoin. De plus, le traitement de vermicompost a produit la biomasse racinaire (45,625 ± 1,812 kg.ha-1), le nombre de grains par plant (391,68 ± 17,20 kg.ha-1) et la biomasse totale des grains de maïs (2608,969 ± 50,914 kg.ha-1) les plus élevés. Conclusions et application des résultats : Les travaux ont révélé l’importance de l’espèce Eudrilus eugeniae dans la formation d’un compost de bonne qualité chimique. Les paysans peuvent utiliser le vermicompost d’ordures ménagères associées aux balles de riz pour améliorer le rendement des cultures de maïs. Mots clés : Vermicompost d’ordures ménagères, Balles de riz, maïs, croissance, rendement. ABSTRACT Objectives: This study aims to produce and determine the fertilizing value of vermicompost, and to measure the effects of this vermicompost on the growth and yield of corn. Methods and results: The work consisted first of all in developing a household waste compost then its associated vermicompost by inoculation of the earthworm Eudrilus eugeniae (Kinb.), and then in evaluating their effects on the production of maize through a trial conducted in the natural environment in Jean Lorougnon Guedé University of Daloa. The treatments consisted of a control consisting of fallow soil, household waste compost associated with rice husks and the corresponding vermicompost. The results revealed that vermicompost has the highest levels of N, P and K, but the lowest concentrations of Cu, Zn Guei et al., J. Appl. Biosci. 2020 Effets du vermicompost à base d’ordures ménagères associées aux balles de riz sur les paramètres agronomiques du maïs (Zea mays L.) 15863 and Pb. Corn plants grow better on vermicompost compared to compost and control. In addition, the vermicompost treatment produced root biomass (45.625 ± 1.812 kg.ha-1), the number of grains per plant (391.68 ± 17.20 kg.ha-1) and the total biomass of grain (2608.969 ± 50.914 kg.ha-1) the highest. Conclusion and application of findings: The work revealed the importance of the species Eudrilus eugeniae in the formation of a compost of good chemical quality. Farmers can use household vermicompost associated with rice hulls to improve the yield of maize crops. Keywords: Household waste vermicompost, rice husks, maize, growth, yield.
