RESUMO: O rabanete é uma planta herbácea de porte reduzido da família brassicaceas, que apresenta ciclo rápido de crescimento. Devido essa característica, é uma planta exigente em nutrientes, devendo ser cultivada em solos férteis. Uma potencial alternativa na fertilização do rabanete é o lodo de curtume, um resíduo de origem animal rico em nutrientes minerais essenciais as plantas. Com intuito de aproveitar os nutrientes contidos nesse resíduo e de conferir uma destinação adequada a esse material, este trabalho objetivou avaliar o lodo de curtume desidratado como adubo alternativo na produção de rabanete. O experimento foi realizado no Instituto Federal de Educação, Ciência e Tecnologia do Espírito Santo, Campus Itapina. Utilizou-se um delineamento em blocos casualizados com quatro repetições e seis tratamentos, contendo diferentes proporções de lodo de curtume misturado ao substrato (10%, 25%, 50%, 75% e 100%). O experimento teve duração de 45 dias, onde as plantas atingiram tamanho comercial e foram avaliadas as características de crescimento, matéria seca e os teores de clorofila. O lodo de curtume apresentou potencial de utilização na produção de rabanete como fonte alternativa de fertilização. O intervalo de recomendação desse resíduo na produção de rabanete está situado entre 32,1 e 47,0%, apresentando ganho nas principais características.

CURTUME SLUDGE AS AN ALTERNATIVE FERTILIZER IN THE RADISH PRODUCTION ABSTRACT: Radish is a small herbaceous plant in the brassicaceas family, which has a rapid growth cycle. Due to this characteristic, it is a nutrient-demanding plant and should be cultivated in fertile soils. A potential alternative for fertilizing radish is tannery sludge, an animal residue rich in essential mineral nutrients for plants. In order to take advantage of the nutrients contained in this residue and to provide an appropriate destination for this material, this work aimed to evaluate the dehydrated tannery sludge as an alternative fertilizer in the production of radish. The experiment was carried out at the Federal Institute of Education, Science and Technology of Espírito Santo, Campus Itapina. A randomized block design with four replications and six treatments was used, containing different proportions of tannery sludge mixed with the substrate (10%, 25%, 50%, 75% and 100%). The experiment lasted 45 days, where the plants reached commercial size and the growth characteristics, dry matter and chlorophyll contents were evaluated. The tannery sludge showed potential for use in the production of radish as an alternative source of fertilization. The recommendation interval for this residue in the production of radish is between 32.1 and 47.0%, showing a gain in the main characteristics.

ABSTRACT The objective of this work was to assess the pulp resistance, soluble solids and yield of watermelon fruits grown under different irrigation managements (determined by the ISAREG model) and mulches, and their interactions. After a survey carried out on local producers, two experiments were conducted, using a completely randomized block design in split-plot arrangement with four replications, in the Teaching, Research and Extension Unit (UEPE) of the Federal Institute of Ceara (IFCE), Jaguaribe-Apodi Irrigation District (DIJA), State of Ceara, Brazil. The treatments consisted of four irrigation managements in the plots, M1 (100% of the available-water capacity (AWC) of the soil), M2 (80%), M3 (60%) and M4 (average water depth used by local producers) and four mulch types in the sub-plots, without mulching (C0) with rice husk (C1), white plastic (C2) and black plastic (C3) as mulches. The results were subjected to analysis of variance, and significant results were subjected to regression (irrigation managements), average test (mulches) and trend graphs (interaction between the factors). The irrigation management practiced during the watermelon crop cycle by the local producers of the Irrigation District of Jaguaribe-Apodi (DIJA) in the State of Ceara, Brazil, is not appropriated, since they usually apply more water than the highest water depth determined by the ISAREG model (100% of the AWC). The plants grown under irrigation water depth of 365.20 mm (M1) and soils with mulches of rice husk or white plastic had the highest yields and fruits with better quality of soluble solids and pulp resistance.

Também, foi verificado se a assistência técnica exerce influência na sensibilização e no conhecimento dos produtores quanto ao uso adequado da água para irrigação no município, para tanto foram aplicados questionários aos produtores. A pesquisa contou com uma amostra de 100 cafeicultores que fazem uso de diferentes tipos de sistemas de irrigação, que foram divididos em dois grupos caracterizados pela localização da propriedade rural em relação à margem do Rio Santa Maria do Rio Doce (SMRD), agrupados também entre aqueles que recebem assistência técnica particular ou pública (CAT) e os que não recebem (SAT). Constatou-se que, em todas as propriedades SAT visitadas (avaliadas), a determinação da duração dos eventos de irrigação é feita arbitrariamente pelo produtor (ou proprietário), sem a utilização de critérios técnicos, contra 92% das propriedades CAT. Quanto à outorga, na margem esquerda do Rio SMRD, 64% dos produtores CAT e 76% dos produtores SAT são outorgados, já na margem direita, 100% dos produtores CAT e 92% dos produtores SAT entrevistados possuem outorga de uso da água.

USE OF WATER AND IRRIGATION MANAGEMENT TECHNIQUES ON COFFEE CONILON CROP 2 ABSTRACT We sought to verify the perception of coffee growers in the municipality of São Roque do Canaã regarding the rational use of water and irrigation management techniques applied on coffee plantations. It was also verified whether technical assistance influences the awareness and knowledge of the producers regarding the proper use of water for irrigation in the municipality, for this purpose, questionnaires were applied to the producers. The survey included a sample of 100 coffee growers who use different types of irrigation systems, divided into two groups characterized by the location of the rural property in relation to Santa Maria of Doce River (SMDR) river bank, grouped among those who receive private or public technical assistance (CAT) and those that do not receive (SAT). It was found that, in all SAT properties visited (evaluated), the determination of the duration of irrigation events is made arbitrarily by the producer (or owner), without the use of technical criteria, against 92% of the CAT properties. Regarding the water use permit, on the left river bank of the SMDR River, 64% of the CAT producers and 76% of the SAT producers have water use permit, while on the right river bank, 100% of the CAT producers and 92% of the interviewed SAT producers have water use permit.

ABSTRACT Reduction of leaf area significantly affects maize productivity, due to its low plasticity. Thus, appropriate water application can minimize this problem, considering that under favorable water conditions the plant would express its maximum production potential. The aim of this study was to evaluate the influence of irrigation on the productive performance of sweet corn submitted to different defoliation levels at the beginning of crop cycle. The experimental design was a randomized block design, arranged in split plot scheme; plots consisting of four water depths [50, 75, 100 and 125% of crop evapotranspiration (ETc)] and the subplots consisted of three defoliation levels [0% (control); 35% (removal of four fully expanded leaves), 100% (total removal of leaves, shoot section)], with three replicates. The use of irrigation has a positive influence on recovery of damages caused by defoliation at the initial development stages of sweet corn, and the success of irrigation management, as a strategy to mitigate damages caused by defoliation, depends on the level of the lost leaf area and the amount of water used.

Robusta coffee plant propagation is recommended to be performed by vegetative methods, one of which is cuttings. Among plant organs that can be used for cuttings is the stem. The research objective was to determine which stem segment from cuttings was able to provide the best root and leaf growth. The layout study used a completely randomized block design (RBD) with an experimental treatment consisting of five stem segments, namely (1) the first stem segment from the upper shoot (A); (2) the second stem segment from the upper shoot (B); (3) the third stem segment from the upper shoot (C); (4) the fourth stem segment from the upper shoot (D); and (5) the fifth stem segment from the upper shoot (E); each treatment had five replications. Data analysis was performed statistically with analysis of variance (ANOVA) and Tukey's HSD (honestly significant difference) test with a significance level of P < 0.05. Robusta coffee cuttings stems from the second stem segment from the upper shoot were able to provide the optimal root growth (root length) and shoot growth (leaf sprout height and leaf sprout growth rate). Leaf sprout number derived from the cuttings was not affected by the stem segment.

Water Tension

Irrigation associated to reduction on planting spaces between rows and between coffee plants has been a featured practice in coffee cultivation. The objective of the present study was to assess, over a period of five consecutive years, influence of different irrigation management regimes and planting densities on growth and bean yield of Coffea arabica L.. The treatments consisted of four irrigation regimes: climatologic water balance, irrigation when the soil water tension reached values close to 20 and 60 kPa; and a control that was not irrigated. The treatments were distributed randomly in five planting densities: 2,500, 3,333, 5,000, 10,000 and 20,000 plants ha-1. A split-plot in randomized block design was used with four replications. Irrigation promoted better growth of coffee plants and increased yield that varied in function of the plant density per area. For densities from 10,000 to 20,000 plants ha-1, regardless of the used irrigation management, mean yield increases were over 49.6% compared to the non-irrigated crop.
