VEGETATIVE GROWTH, YIELD AND FRUIT QUALITY OF PINEAPPLE CROP ‘BRS IMPERIAL' UNDER IRRIGATION DEPTHS     2 ABSTRACT   Knowing the hydric demand of a crop in a region enables better irrigation management and crop development. Thus, this study aimed to evaluate the vegetative growth, physical-chemical quality of the fruits and the yield of the pineapple crop ‘BRS Imperial’ under irrigation depths in coastal conditions, in the state of Espírito Santo (ES). The experiment was conducted at the Federal University of Espírito Santo, municipality of São Mateus, in a randomized block design, with seven irrigation depths (0%, 25%, 50%, 75%, 100%, 125% and 150% of the evapotranspiration of the crop (ETc)), four replications and six useful plants per plot. The vegetative characteristics of the plant and the physicochemical characteristics of the fruits were evaluated, as well as the yield. The results were subjected to analysis of variance. For the conditions under study, the highest plant height and stem diameter observed were 28.8 cm and 65.1 mm, respectively, both in the applied irrigation depth referring to 69% of the replacement of the ETc. For the physical-chemical characteristics analyzed, the applied irrigation depths did not significantly influence the crop. The yield obtained was 40.41 t ha-1, with an average content of total soluble solids of 16.46 ºBrix, higher than the minimum required for harvest and commercialization.   Keywords: Ananas comosus (L.)

A escassez de informações referentes ao consumo hídrico de mudas de espécies florestais freqüentemente dificulta o planejamento da irrigação em viveiros comerciais, levando muitas vezes, a adoção de medidas ineficientes de manejo, provocando perda no padrão de qualidade das mudas. Dessa forma, procurou-se neste trabalho investigar a máxima capacidade de retenção de água (MCRA) no substrato em que as mudas de eucalipto podem ser submetidas e determinar o coeficiente de cultivo (Kc) para o clone híbrido de E. urophylla x E. grandis. O estudo foi realizado em casa de vegetação, localizada na área experimental do Programa de Pós-Graduação em Ciências Florestais vinculado ao Centro de Ciências Agrárias da Universidade Federal do Espírito Santo (CCA-UFES) no município de Alegre, ES, montado num delineamento inteiramente casualizado, com cinco tratamentos de disponibilidade hídrica no substrato (90, 80, 70, 60 e 50% da MCRA), com quatro repetições. De acordo com os resultados obtidos, verificou-se que a disponibilidade hídrica no substrato de 70% da MCRA pode ser utilizada para a produção de mudas clonais de eucalipto, sem afetar o crescimento e o padrão de qualidade. O Kc estimado para as mudas de eucalipto em condições de viveiro foi de 1,25. AbstractDetermination of maximum capacity of water retention in substrate for production plants in Eucalyptus nursery. The scarcity of information regarding water consumption of seedlings of forest species often complicates the planning of irrigation in commercial nurseries, often leading the adoption of inefficient management measures, causing loss in the quality of seedlings. Thus, this study sought to investigate the capacity of water retention in the substrate in which the eucalyptus seedlings can be submitted and determine the crop coefficient (Kc) for the hybrid clone of E. urophylla x E . grandis. The study was conducted in a greenhouse located in the experimental area of the Post-Graduation of Forest Sciences bound to the Center for Agrarian Sciences, Federal University of Espírito Santo in the city of Alegre, ES, built in a completely randomized design with five treatments of water availability in the substrate (90, 80, 70, 60 and 50% of MCRA) and four replications. According to the results, it was found that water availability in the substrate MCRA of the 70% can be used for the production of minicutting, without affecting standards of growth and quality. The Kc for eucalyptus seedlings in nursery conditions was 1.25.Keywords: Coefficient of cultivation; irrigation management; Eucalyptus urophylla x E. grandis.

The objective was to evaluate the production and post-harvest quality of fruit from grafted and non-grafted tomatoes. The experiment was carried out in a randomized block design with five treatments (Jiloeiro, Berinjeleira, Jurubeba, 'Intacto' rootstock and the witness the cherry tomato without grafting) and 16 replicates. In the evaluation of physical-chemical quality, the experiment followed a randomized block design in a 5x2 factorial scheme (rootstocks and storage temperatures, 10 ºC and room temperature) four replications. For a better productive contribution of the cherry tomato, the use of rootstocks from Jurubeba and Intacto is indicated, however, the use of a rootstock did not contribute to the durability and physicochemical characteristics of the fruit. When conditioned at 10 ºC, the fruits showed a better visual and physical-chemical aspect in relation to the ambient temperature, with increased durability of the product in all treatments.

Pineapple is a crop of great importance for the economic stability of a large number of Peruvians; however, in areas experiencing low degrees of technological intervention, farmers generally adopt low planting densities. The objective of this study was to determine the effect of three plantation densities (35700, 47600, and 55500 plants ha−1) on the agronomic performance and fruit quality of three pineapple cultivars (“Golden,” “Smooth Cayenne,” and “Santa Rosa” ecotype). The experiment was performed under a randomized complete block design (RCBD) in a factorial arrangement, and the data were subjected to analysis of variance and the Tukey test ( p < 0.05 ). The results show significant differences in terms of plant height and D-leaf length, with “Golden” being the cultivar that achieved the best performance at the three planting densities. The diameter (11.77–13.29 cm) and weight of the fruit without a crown (1.48–1.85 kg) were not affected by the treatments; in contrast, the length and weight of the fruit with a crown did exhibit significant variations, highlighting the “Smooth Cayenne” cultivar and “Santa Rosa” ecotype at a density of 55500 plants ha−1, respectively. The highest estimated yield (>100 t ha−1) for the three pineapple cultivars was recorded at a density of 55500 plants ha−1. The content of total soluble solids was higher in the “Golden” cultivar, but in general, all the fruits exceeded the established standards. Based on the results, it is recommended that farmers in the area and those with similar conditions establish a planting density of 55500 plants ha−1 because it improves the yield without damaging the quality of the fruit of the pineapple cultivars evaluated.

ABSTRACT The netted melon requires special growing conditions, including a protected environment, an adequate staking system and proper water and nutrient management. This study aimed to assess the effect of irrigation levels and silicon doses on the yield and quality of Sunrise hybrid melons, in a greenhouse. A randomized block design was used, with a 5 x 3 factorial scheme and four replications. The first factor consisted of five silicon doses (0 kg ha-1, 50 kg ha-1, 100 kg ha-1, 150 kg ha-1 and 200 kg ha-1) and the second of three irrigation levels (40 %, 70 % and 100 % of the ETc). The results demonstrated that the applied irrigation levels and silicon doses have no influence on the yield traits of melon plants. The irrigation level corresponding to 100 % of the ETc promotes higher values for soluble solids (9.86 ºBrix) and maturation index (114.9) on fruits. The increase of silicon doses up to 200 kg ha-1 also increases the maturation index in the treatment with the greatest irrigation level and reduces this index at the shallowest level applied.

In Brazil 95% of the passion fruit marketed comes from the species Passiflora edulis f. flavicarpa (yellow passion fruit), the remainder are Passiflora edulis f. edulis (purple passion fruit) and Passiflora alata (sweet passion fruit), considered market niches. Because of the wide genetic variability the genus Passiflora, it is of fundamental importance to identify superior genotypes to improve the quality of fruit for the fresh market. The objective is to analyze the physical and chemical characteristics of the fruits of 33 genotypes P. alata Curtis, evaluated in a randomized complete block design with two replicates of four plants, from native matrices, located at the experimental farm of the University Center of the North of Espírito Santo, Federal University of Espírito Santo, in the Northern Region of the state of Espírito Santo, São Mateus -ES. Thirty-two mature fruits were collected in each replicate, eight per plant and the following characteristics were analyzed: fruit weight (g); equatorial and polar diameter of fruit (cm); peel thickness (mm); mass of the pulp (g); pulp volume (mL); pulp yield (%); number of seeds per fruit, pH; soluble solids (SS); titratable acidity (TA) and ratio (SS/TA). There is a wide genetic variability among P. alata genotypes as to the traits assessed. Genotypes 4, 6, 8, 11, 15, 18, 21, 25 and 26 stood out among the rest, and is therefore recommended for new plantings and future breeding programs.

Altitude and climate and its microclimatic characteristics influence the grapes and wines quality. The objective of this study was to evaluate ‘Niagara Rosada’ and ‘Isabel’ grapes quality at three different altitudes in the highlands of the state of Espírito Santo. The experiment was a randomized complete block design in subdivided plots (3x2). The plots were in different altitudes and, in the subplots, the two cultivars. Also, five replicates were done in each treatment. The grapes quality were evaluated in the laboratory from total soluble solids (TSS), total titratable acidity (TTA), pH and the relationship between TSS / TTA. The cultivar ‘Niágara Rosada’ showed higher values than the ‘Isabel’ cultivar in relation to the evaluated parameters. The altitude of 650 m favored to obtain higher values of total titratable acidity and lower values of pH. The excess of leaf nitrogen in environment 1 contributed to the higher values of TTA and lower pH for the cultivars ‘Niágara Rosada’ and ‘Isabel’. The quality of the ‘Niágara Rosada’ and ‘Isabel’ grapes produced in the state of Espírito Santo were influenced by altitude, and the altitude of 650 m favored to obtain higher values of total titratable acidity and lower values of pH.

This study was aimed at observing the effect of the grafting of tomato plants on morphological (vegetative growth), production and nutritive characteristics (quantity and quality of production). For this purpose, the ‘Lorely F1’ cultivar was used as a scion grafted onto the ‘Beaufort’ rootstock. Plants were cultivated with a stem and two stems. The observations collected in this study were concerned with the characteristics of plant growth. The studied morphological characteristics were plant height, stem diameter and number of leaves, and the studied production characteristics were the characteristics of fructification and productivity (the average number of fruit per plant, the average weight of the fruit, production per plant). Particular attention was paid to the nutritional characteristics of the fruit, to the fruit quality (total soluble solids, total sugar, acidity, vitamin C, antioxidant activity (by the Trolox method) and the contents of lycopene and beta-carotene). The results showed that grafting positively influenced the growth and production characteristics. Grafting of tomato plants had an appreciable effect on the vegetative growth of the variant 2-grafted tomatoes with a stem. The best option in terms of productivity and production was the variant 3-grafted tomatoes with two stems, which yielded 9.2 kg per plant. Fruit quality was not improved in any of the grafted variants.

Among the problems faced by the melon crop in the state of Rio Grande do Norte, northeastern Brazil, the effect of water and soil salinity is considered one of the key factors to limit fruit production and quality. The aim of this work was to study the effects of using irrigation waters with different salinity levels on yield and quality of fruits of the yellow melon hybrid Mandacaru. A randomized complete block design was used with five treatments (irrigation water salt concentrations: 0.54, 1.48, 2.02, 3.03, 3.9 dS m-1) and four replications. The effects of these concentrations were evaluated through, number of marketable fruits per plant, marketable and total fruit yield, average marketable fruit mass, soluble solids content and pulp firmness. Increment in water salinity level negatively influenced crop yield. The 3.9 dS m-1 salinity level caused yield losses of 20.31%, due to the reduction of fruit number per plant. The highest soluble solid content and the highest pulp firmness values were estimated to occur at salinity levels 2.09 and 3.5 dS m-1, respectively.
