The radish is a Brassicaceae with small size, adapted to regions with mild temperatures between 13 and 20 °C and short days. However, there are cultivars adapted to high-temperature conditions, which has allowed the cultivation of this tuberous vegetable throughout the year, even in tropical regions. The present work had as objective evaluate the agronomic performance and yield of six cultivars of radish, in Uruçuí - PI. The experimental design was in randomized blocks, with four replicates and six cultivars. Harvest was performed according to the cycle of each cultivar. Number of leaves per plant, fresh and dry mass of shoot and root, diameter, and root length and yield were evaluated. The cultivars Margaret Queen and Crimson Gigante presented better root development, both in diameter and length, and obtained higher productivity per ha, being these two the most indicated for the region. The Sparkler cultivar was one of the ones that produced the highest fresh mass of the aerial part, but it obtained lower commercial roots yield, being the least indicated for the municipality of Uruçuí-PI.

Shading Screens and mulching may provide a favorable environment for radish growing in regions of adverse climates. This work aimed to evaluate the radish productivity under the influence of different shading screens associated with the presence and absence of mulch in two different years. The experiment was carried out in two different seasons (2017 dry season and 2018 rainy season), in the vegetable garden of Liberdade campus, at the University of International Integration of Afro-Brazilian Lusophony (Unilab), municipality of Redenção-CE. The experimental design was in randomized blocks in a split-plot arrangement, with four repetitions, in which the plots consisted of growing with and without mulching and in the subplots, five shading screens: 50% Black Shading Screen (50% BSS), 50% Red Shading Screen (50% RSS), 30% White Shading Screen (30% WSS), 70% Black Shading Screen (70% BSS) ), and full sunlight (FS). The red shading screens 50% and white 30%, in addition to cultivation under full sunlight, provide higher performance in terms of the number of leaves, tuberous root diameter, tuberous root matter, and the radish crop productivity, regardless of the evaluated period. The applied mulch does not influence the productivity of the rabante, influencing only the gain of dry mass of the aerial part, soluble solids and length of the tuberous root.

Radish yield and quality are factors influenced by water stress that may occur during periods of drought or irrigation handled inappropriately, interfering negatively in plants development, producing radishes of inferior quality and in lesser quantity. In addition to irrigation, which makes water available in the system, it is important to maintain it with the use of water-retaining products such as hydrogel. The aim of this work was to evaluate radish yield, submitted to three different hydrogel doses combined with two water slides. The experimental design was in factorial scheme 3 x 2, with three water slides (50%, 75% and 100% Eto – reference evapotranspiration estimate) and two hydrogel doses (40 and 60 g m-2) with four replicates. Number of leaves, horizontal and vertical root diameter (mm), total and shoot length (cm), fresh mass of root and shoot (g), dry mass of shoot and root (g) and yield (t ha-1) were evaluated. The best results, regarding radish production and development, were obtained when using 50% of Eto with 60 g m-2 of hydrogel in combination. Thus, radish cultivation in oxisoil was influenced by the use of hydrogel, which provided a more efficient water level use.

O meloeiro tem grande importância econômica para o Nordeste brasileiro. Entretanto, em seu cultivo utiliza-se insumos que podem prejudicar o ambiente; como, os fertilizantes nitrogenados. Objetivou-se avaliar a emissão de N2O em cultivo de meloeiro amarelo ‘Goldex’. O experimento foi instalado em delineamento inteiramente casualizado, com cinco repetições. Os tratamentos foram: 0 (controle), 1,0; 1,5 e 2 vezes a quantidade de nitrogênio recomendada para cada estádio. Foi analisado o fluxo de N2O, área foliar, número de folhas, massa seca da parte aérea, massa seca dos frutos, massa seca da parte radicular, nitrogênio total do solo, das plantas e N (NH4+ e NO3-) do solo. O fluxo de N2O teve comportamento temporal irregular durante a fase de plântulas e crescente na floração. Os tratamentos afetaram significativamente a área foliar, número de folhas, massa seca da parte aérea, massa seca da parte radicular, nitrogênio da parte aérea e parte radicular das plantas e do solo. A aplicação de nitrogênio, em dosagens superiores à recomendada, não aumentou a produção do meloeiro. E o cálculo do fator de emissão mostrou que a emissão do N2O não atingiu valores prejudiciais ao ambiente.Palavras-chave: fator de emissão, efeito estufa e nitrogênio. NITROUS OXIDE EMISSION ASSOCIATED WITH UREA USE THE YELLOW MELON CROP ABSTRACT: The melon has great economic importance for the Brazilian Northeast. However, in its cultivation uses inputs that can harm the environment; Such as nitrogen fertilizers. The objective of this study was to evaluate the emission of N2O in yellow 'Goldex' cultivar. The experiment was installed in a completely randomized design with five replications. The treatments were: 0 (control), 1.0; 1.5 and 2 times the amount of nitrogen recommended for each stage. N2O flux, leaf area, leaf number, shoot dry mass, fruit dry mass, dry mass of the root portion, total soil nitrogen, of the plants and N (NH4 + and NO3 -) of the soil were analyzed.

The purpose of this study was to evaluate the effect of different combinations of products applied through seed treatment, associated with the inoculation, in the development of soybean plants. The experiment was conducted in a greenhouse at Federal University of Lavras (UFLA). The experimental design was a randomized complete block, with four repetitions in a factorial 4 × 11, being four soybean cultivars and 11 combinations of products associated with the inoculation in the treatment of seeds. At the stage (R1) it was evaluated: plant height, leaf area, foliar chlorophyll content, number of trifoliate leaves, dry shoot mass, dry root mass, root length, root volume, nodules total number, viable nodules total number, nodules dry mass and foliar nitrogen content. The combination of products in the treatment of seeds, do not present phytotoxic effects in the characters related to the development, except for dry matter of aerial part and root volume. The combination of products in treatment of seeds influences negatively the nodulation, especially in the treatments with presence of nematicide. The inoculation performed in isolation or combined with fungicide and insecticide (I+FI) maintains nodule levels.

A produtividade florestal depende das potencialidades genéticas das matrizes, do ambiente proposto pelos substratos, frequência de irrigação, disponibilidade de luz, nutrição e das condições fitossanitárias. Assim, objetivou-se com o presente estudo analisar os efeitos da aplicação de potássio e de irrigação na qualidade de mudas de Eucalyptus urophylla. Para tal adotou-se o delineamento experimental em parcelas subdivididas definindo as 2 lâminas de irrigação (10 mm e 15 mm) como parcelas e os 5 níveis de potássio (0; 1,2; 2,4; 4,8; e 9,6 g L-1) como subparcelas, em 5 repetições compostas por 9 plantas. A comparação entre os métodos foi feita através teste de Tukey com 5% de probabilidade. Aos 120 dias, foram avaliadas: altura da parte aérea, diâmetro do colo, massa seca da parte aérea e da raiz. O tratamento testemunha apresentou as melhores médias em todos os parâmetros, sendo considerado o mais eficiente. A lâmina de irrigação de 15 mm foi considerada a mais eficiente. Portanto, conclui-se que qualquer que seja o incremento de potássio na produção de mudas, o mesmo deve se relacionar harmonicamente com a quantidade pré-existente no substrato base e com as exigências da cultura, de maneira que haja equilíbrio entre todas as partes. Palavras-chave: manejo hídrico; rustificação; substrato; casa de sombra.   IRRIGATION AND POTASSIUM LEVELS IN THE QUALITY OF EUCALYPTUS   ABSTRACT:  Forest productivity depends on the genetic potential of the matrices, the environment proposed by the substrates, frequency of irrigation, availability of light, nutrition and phytosanitary conditions. Thus, the aim of this study was to analyze the effects of potassium and irrigation on the quality of Eucalyptus urophylla seedlings. For this purpose, the experimental design was adopted in subdivided plots, defining the 2 layers of irrigation (10 mm and 15 mm) as plots and the 5 levels of potassium (0; 1.2; 2.4; 4.8; and 9.6 g L-1) as subplots, in 5 repetitions composed of 8 plants. The comparison between the methods was made using the Tukey test with a 5% probability. At 120 days, the following were evaluated: height of the aerial part, diameter of the neck, dry mass of the aerial part and the root. The control treatment showed the best averages in all parameters, being considered the most efficient. The 15 mm irrigation blade was considered the most efficient. Therefore, it is concluded that whatever the potassium increase in the production of seedlings, it must be harmoniously related to the pre-existing quantity in the base substrate and to the requirements of the culture, so that there is balance between all parts.

Objective. We evaluated the effect of arbuscular mycorrhizal inoculation in Citrusvolkameriana Tan & Pasq plants with the application of Glomus spp Zac- 19 (G.claroides, G. diaphanum and G. albidum) to assess growth under greenhouseconditions without fertilizer application.Methodology. The evaluated treatments were inoculation with 2,4,6,8, and 10 g ofinoculum, plus a control without inoculation in an experimental design of completerandomized blocks with three replications. Variables were plant height, stem diameter,number of leaves, foliar area, dry weight, and mycorrhizal colonization.Results. A statistically significant response (p?0.01) to inoculation wasobserved, registering higher growth of mycorrhizal plants. The inoculation wasconsidered appropriate for all the levels evaluated. The outstanding treatment was 10 gof inoculum that produced plants with 110.16 cm in height for the last sampling; 38.56leaves per plant; 1.13 cm stem diameter; 35.95 g dry weight of root; 76.88 g dry weightof the aerial part of the plant; 225.03 cm 2 of leaf area per plant and 88.87% ofmycorrhizal colonization.Conclusions. The application of 10 g per plant to the roots of Citrus volkameriana fromthe Glomus Zac-19 arbuscular mycorrhizal consortium promoted the production of morevigorous plants for grafting, without the application of chemical fertilizer.

Lettuce plants, cv. Vera, were grown under five salinity levels in a hydroponical experimental set-up using a 0.15 m deep sand growing bed. A standard nutrient solution was used, with the following composition, in mmol L-1: 16.9 NO3-; 2.0 H2PO4-; 1.0 SO4- 4.0 Ca++; 10.9 K+ e 1.0 Mg++, and, in mg L-1, 0.42 Mn; 0.26 Zn; 0,05 Cu; 0,50 B; 0,04 Mo, and 4.82 chelated Fe. The five salinity levels compared as treatments were obtained by varying the concentration of the standard nutrient solution, reaching average electrical conductivities (EC) of 0.80; 1.93; 2.81; 3.73 and 4.72 dS m-1, for T1, T2, T3, T4 and T5, respectively. The nutrient solution at each salinity level was supplied from a reservoir by means of a flooded-type electrical pump, for 15 minutes, at intervals of 90 minutes during the day and 420 minutes during the night. A completely randomised experimental design was used with four replications and 20 plants per plot. Four plants of each plot were harvested at 32 days after planting, to determine shoot and root dry mass, shoot fresh weight, leaf area and number of leaves per plant. Number of leaves was 18 per plant and was not affected by treatments. Dry mass of leaves increased 24,4% from T1 to T3. No relationships were found on data from stem and root dry mass. A positive effect of EC was recorded on shoot fresh mass, which increased 28.5% from T1 to T2, and decreased 16.5% from T2 to T5. Maximum LAI estimated value was 4.3 m² m-2 for an EC of 2.6 dS m-1. Salinity levels above 2.0 and 2.6 dS m-1 reduce fresh yield and plant growth, respectively.

Guabiju tree is usually propagated by seeds, although this method presents disadvantages, such as a long juvenile period and great genetic variability, resulting in uneven plants which makes management and the establishment of commercial orchards difficult, in addition to the delay in the production entry. The objective of this work was to test the propagation technique by mini-cutting in guabiju tree. The experimental design used was completely randomized, with a 2 x 2 x 3 factorial (ontogeny of the matrix plant x cut length x IBA concentration), with four replications and 20 mini-cuttings per experimental unit. A hundred and twenty days after the implantation of the experiment, the rooting percentage and callogenesis of the mini-cuttings, the secondary root total length, the aerial part and number of leaves were evaluated. The rooted mini-cuttings were transplanted into larger containers with substrate, and after 60 days of transplantation, their survival percentage was analyzed. The highest rooting percentage was obtained with 0 mg L-1 of IBA with an 57.69% average. Mini-cuttings had a high percentage of survival, with 87.5% being the lowest, presenting a satisfactory result. For the guabiju tree propagation by mini-cutting, it is recommended not to use IBA and adopt a length of four centimeters, using a juvenile matrix plant.
