The investigation evaluated the effect of fertilizers potásicos with fosfitos on the yield of grain of hard corn (Zea mays L.), in the Property "Santiago", located in the Km 26 way Babahoyo-San Juan, county of Los Ríos. A rehearsal settled down in the hybrid corn DK-7088, measuring the answer from the corn to the application of fertilizers potasic and fhosphite, to determine the dose with more effect on the production. 19 treatments were proven with Chloride of potassium, Sulfate of potassium and Nitrate of potassium, with fhosphite of Calcium, Magnesium and Potassium, more a witness without applications. The used experimental design was complete Blocks at random in three repetitions, the evaluated variables were subjected to the variancia analysis, and the test was applied from Tukey to 95% of probability. The evaluated parameters were: plant height, days to flowering, longitude and ear diameter and yield for hectare. Found increases in grain yield with three treatments, highlighting the treatment with the application of muriate of potash in conjunction with Calcium phosphide (9451,65 kg ha1 ). The results indicate the possibility of increases of more than 49% in relation to the witness (6339 kg ha1 ) where there was applied the treatments.

 RESUMO - O objetivo do trabalho foi avaliar o desempenho agronômico e econômico na cultura do milho verde submetida ao uso de bioestimulantes na presença e ausência de fungicida. Dessa forma, dois experimentos foram conduzidos em anos distintos, em delineamento experimental de blocos ao acaso com três repetições, em arranjo fatorial 4x2. O primeiro fator correspondeu à combinação de bioestimulantes (Ausência, MC Cream, MC Extra, MC Cream+MC Extra) e o segundo fator à presença e ausência de fungicida (piraclostrobina + epoxiconazole). Foi avaliado o peso de espigas verdes, a altura de plantas, diâmetro de colmo, teor de clorofila e severidade de doenças, além da viabilidade econômica dos tratamentos. Os Bioestimulantes, na ausência de fungicida, foram eficientes para aumentar o peso das espigas verdes, altura de plantas, e o teor de clorofila. Na presença do fungicida os bioestimulantes aumentaram o diâmetro de colmo e reduziram a severidade de doenças. Os investimentos em insumos elevaram os custos de produção, porém a rentabilidade foi compensada pelo aumento da renda bruta. Em situação de baixa disponibilidade hídrica, o bioestimulante MC Extra foi o mais viável economicamente para a cultura do milho verde.Palavras-chave: fitossanidade, produtividade, renda líquida, Zea mays L. EFFICIENCY OF BIOSTIMULANTS AND FUNGICIDE IN THE AGRONOMIC AND ECONOMIC CHARACTERS OF GREEN CORN  ABSTRACT – The objective of this work was to evaluate the agronomic and economic performance of the green corn crop, subjected to the use of biostimulants in the presence and absence of fungicide. Two experiments were conducted in different years using a randomized block design with three replications, in a 4x2 factorial arrangement. The first factor corresponded to the combination of biostimulants (Absence, MC Cream, MC Extra, MC Cream + MC Extra) and the second factor was the presence and absence of fungicide (pyraclostrobin + epoxiconazole). Green ear weight, plant height, stem diameter, chlorophyll content and severity of diseases were evaluated, as well as the economic viability of the treatments.In the absence of fungicide, biostimulants were efficient to increase the green ear weight, plant height, and chlorophyll content. In the presence of the fungicide, biostimulants increased stem diameter and reduced disease severity. Investments in inputs increased production costs, but profitability was offset by the increase in gross income. In a situation of low water availability, the biostimulant MC Extra was the most economically viable for the green maize crop.Keywords: plant health, productivity, net income, Zea mays L.

Aluminum (Al) toxicity is one of the most limiting factors for productivity. This research was carried out to assess the influence of Al nutrient solution on plant height, dry weight and morphoanatomical alterations in corn (Zea mays L.) roots and leaves. The experiment was conducted in a greenhouse with five treatments consisting of Al doses (0, 25, 75, 150, and 300 µmol L-1) and six replications. The solutions were constantly aerated, and the pH was initially adjusted to 4.3. The shoot dry matter, root dry matter and plant height decreased significantly with increasing Al concentrations. Compared to the control plants, it was observed that the root growth of corn plants in Al solutions was inhibited, there were fewer lateral roots and the development of the root system reduced. The leaf anatomy of plants grown in solutions containing 75 and 300 µmol L-1 Al differed in few aspects from the control plants. The leaf sheaths of the plants exposed to Al had a uniseriate epidermis coated with a thin cuticle layer, and the cells of both the epidermis and the cortex were less developed. In the vascular bundle, the metaxylem and protoxylem had no secondary walls, and the diameter of both was much smaller than of the control plants.
