Studies related to adaptation to the environment and different conditions of water availability contribute to decision-making regarding the management of any crop to be implanted. Accordingly, this work aimed to evaluate the yield and quality of organic yellow passion fruit cultivated in a long root system in dryland conditions. The experimental design was in randomized blocks, with five treatments and four replications with four plants each. The treatments consisted of the alteration of the length of the root system, namely: T1 = 25 cm; T2 = 50 cm; T3 = 75 cm; T4 = 100 cm; and T5 = 125 cm. At 120 days after emergence (DAE), the seedlings were transplanted to the field and the following variables were evaluated: plant height (cm) and base diameter (mm) at 120 DAE; total titratable acidity (TTA), total soluble solids (TSS), Ratio (TSS/TTA); and fruit yield. The cultivation of tall seedlings with a long root system provides the maintenance of production during the dry season. The TTA, TSS, and the ratio do not change when modifying the length of the root system, although they do change with the harvest season. The cultivation of passion fruit in an organic system using plants with a long root system with an estimated length of 114 cm provides a higher fruit yield (7,472 kg ha-1) in 22 months of cultivation.

ABSTRACT The use of organic fertilizers can improve the chemical, physical, and biological properties of the soil, with their use implying low environmental impact. This study aimed to evaluate the yield and quality of yellow passion fruit grown in an organic system associated with irrigation and input levels. A randomized complete block design in a 3x2 factorial arrangement with four replications was adopted. The factors evaluated were: three input levels (fertilizers and alternative pesticides) and the presence or absence of irrigation. Fertilization consisted of the application of 5, 10, and 15 liters of organic compost per plant and 500, 1,000, and 1,500 g of lime per plant, corresponding to input levels 1, 2, and 3, respectively. Topdressing fertilization was split into two applications, corresponding to 118, 235, and 353 g per plant of thermophosphate and 59.1, 118.20, and 176.40 g per plant of potassium sulfate for levels 1, 2, and 3 of input application, respectively. The alternative pesticides were sprayed every 30, 15, and 7 days for levels 1, 2, and 3, respectively. The number of fruits per plant and the yield increased using the input level 3 associated with irrigation. In the absence of irrigation, input levels 2 and 3 increased the content of soluble solids. The titratable acidity, TSS/TTA ratio, and the fruits classified as extra did not differ significantly between treatments. Input levels 1 and 2 associated with the absence of irrigation increased the percentage of fruits classified as commercial.

Abstract The aim of this work was to evaluate the effect of irrigation and deep planting of tall yellow passion fruit seedlings in the organic system on fruit quality and productivity. A randomized complete block design with 2x4 subdivided plots, with 8 treatments and 4 blocks was used, with irrigated and rainfed systems being plots and 4 planting depths (0.20 m, 0.40 m, 0.60 m and 0.80 m) subplots. Seedlings aged 90 days and 2 m in height were used. Before planting, all stem leaves were removed from seedlings to be buried and to IBA at concentration of 4,000 mg kg-1 was applied. The number of fruits per plant, average fruit mass and total productivity and of 1st and 2nd crops, as well as total soluble solids (TSS), total titratable acidity (TTA), ratio (TSS/TTA), commercial and equatorial diameter classification were estimated. Irrigated planting at depths of 0.20 m and 0.40 m was more productive in the first crop, but there was no difference in the total productivity and in the second crop. Neither irrigation nor plant depth altered the chemical quality of fruits and commercial classification.

ABSTRACT The aim of the present study was to evaluate the effect of stem repair grafting on the recovery of damaged plants, yield and quality of yellow passion fruits in organic system. The experiment was conducted simulating five stem damages (treatments) in randomized complete block design with four replications of four plants each. After reaching on average 7.3 ± 1.2 mm in stem diameter, plants were perforated at 20, 40, 60 and 80% of the stem diameter with the aid of a steel drill. The reduction in plant stand treatment with 80 % damage reduces plant productivity. Then, bridge-type grafting was performed by connecting the top and bottom of the injury. The grafting success percentage ranged from 81.3 to 95.8% and did not differ between treatments, but the survival rate of plants was lower in treatments with 40 and 80% of injuries. There were no statistically significant differences between treatments for the following variables: number of fruits per plant, average fruit weight, total soluble solids (TSS), total titratable acidity (TTA) and (TSS/TTA) ratio. Recovery stem grafting allows injured plants to maintain the same productivity by up to 60% compared to plants without injuries.

Despite the importance of passion fruit for the Brazilian fruit market, there are still many agronomic and fruit quality problems to be solved, in order to increase this crop performance. The objective of this study was to evaluate the quality of twelve genotypes of wild, sweet and yellow passion fruit, aiming to identify promising materials considering fruit quality, in Federal District, Brazil. An experiment was carried out at the Água Limpa Farm of the Universidade de Brasília (UnB) from 2016 to 2018, in a randomized block design, with 12 treatments, 4 replicates and 6 plants/plot. At the harvesting time, six fruits per plot were randomly collected for the following physicochemical analysis: fruit mass, pulp mass with and without seeds, length/longitudinal diameter, width/transverse diameter, length/width ratio, husk thickness, predominant color of the pulp (L*, C*, h*), number of seeds, seed size, total soluble solids content, total titratable acidity, total soluble solids/total titratable acidity ratio and pH. High heritability values ​​and relation of genetic/environment variation coefficients ratio were observed for most of the characteristics evaluated. The genotypes of yellow passion fruit MAR20#21 P2 x FB 200 P1 R2 and MAR20#19 ROXO R4 x ECRAM P3 R3 showed the best characteristics of fruit mass and pulp mass with seed. All the genotypes studied showed values ​​of total soluble solids above 11ºBrix. Positive and significant correlation was observed between fruit mass and length/width ratio, indicating that oblong fruits have higher fruit mass.

O experimento foi desenvolvido em um Neossolo Quartzarênico no município de Tianguá, Ceará, Brasil. Os tratamentos foram organizados no esquema 2 × (3 × 5), sendo a parcela principal as lâminas de irrigação (100 e 70% da ETc) e as subparcelas as combinações entre matéria orgânica (sem, esterco bovino e cama de frango) e fósforo (0, 40, 80, 120, 160 de P2O5 kg ha-1), sendo distribuídos em blocos casualizados. Avaliou-se a produção (massa média do maracujá, frutos por planta e produtividade) e qualidade pós-colheita (pH, acidez titulável, teor de sólidos solúveis e a razão sólidos solúveis/acidez titulável). A redução em 30% da lâmina de irrigação não acarretou perdas na produção, porém reduziu os sólidos solúveis com menor intensidade nas covas com matéria orgânica. Entre as fontes orgânicas, a cama de frango proporcionou maior número de frutos. O fósforo aumentou o número de frutos, produtividade e sólidos solúveis. No cultivo do maracujazeiro-amarelo em Neossolo recomenda-se utilizar cama de frango como fonte orgânica, aplicar 100 kg ha-1 de P2O5 e lâmina de irrigação de 70 a 100% da ETc.   Palavras chave: Passiflora edulis, irrigação, insumo orgânico, fósforo, produtividade.     MEDEIROS, S.

YIELD AND POSTHARVEST QUALITY OF YELLOW PASSION FRUIT UNDER WATER IRRIGATION DEPTHS, PHOSPHATE AND ORGANIC FERTILIZATION                                                           2 ABSTRACT   This study aimed to evaluate yield and postharvest quality of yellow passion fruit under irrigation depths, organic and phosphate fertilization. The experiment was carried out in a Quartz-sand Neosol located in the city of Tianguá, Ceará state, Brazil. The treatments were arranged in a 2 × (3 × 5) scheme, with main plots composed of irrigation depths (100 and 70% of ETc) and subplots composed of combinations of organic matter (without, cattle manure and chicken litter) and phosphorus. (0, 40, 80, 120, 160 of P2O5 kg ha-1), distributed in randomized blocks. The production (average passion fruit mass, fruits per plant and yield) and postharvest quality (pH, titratable acidity, soluble solids content and soluble solids/titratable acidity ratio) were assessed. The decrease by 30% in irrigation depth did not cause losses in  production, however, it reduced the soluble solids with lower intensity in treatments with organic matter. Among the organic inputs, chicken litter provided the highest number of fruits. Phosphorous fertilization increased fruit number, yield, and soluble solids. For the production of yellow passion fruit in  Neosol it is recommended to use chicken litter as organic input, with 100 kg ha-1 of P2O5 and 70 to 100% ETc irrigation depth.   Keywords: Passiflora edulis, irrigation, organic input, phosphorus, yield.

The strawberry cultivation is an important economic activity in the Rio Grande do Sul State, Brazil, however the number of offered cultivars to the growers is reduced. The yield and quality of strawberry (Fragaria x ananassa Duch.) cultivars Camarosa, Galexia, Earlibrite, Festival, Plarionfre and Sabrosa was evaluated under the climatic conditions of Pelotas, Rio Grande do Sul State. We determined the number, mass, total soluble solids (TSS ºBrix), total titratable acidity (TTA), antocianin level and fresh fruits produced in an experimental unit. We also determined the production of fruits per hectare and per plant. The statistical design used in the experiment was of completely randomized blocks with 6 treatments (cultivars) and 4 replicates where the experimental unit was composed of 8 plants. The harvest began in the first half of August, extending to the second half of December, totalling 20 weeks. Plarionfre, Earlibrite and Festival cultivars showed higher production from the first half of October until the end of the first half of November. Camarosa reached higher productivity, mass of plants and fruit weight. There were no differences between the evaluated cultivars in the levels of TSS, antocianin, ATT and pH during the period of evaluation.

The experiment of the present research work was conducted during summer season of 2018-19 and 2019-20 at Horticulture Research Farm-I, Department of Horticulture, School of Agricultural Sciences and Technology, Babasaheb Bhimrao Ambedkar University (A Central University), Vidya-Vihar, Rae Bareli Road, Lucknow (U.P.), India. The analysis of variance clearly reveals significant differences among the genotypes for all characters. The observations recorded on various characters showed that the estimates of phenotypic coefficient of variation (PCV) were higher than genotypic coefficient variation (GCV) for all characters. The high phenotypic as well as genotypic coefficient of variation were observed in marketable fruit yield per plant (39.36%) followed by average fruit weight (29.73%) and number of branches per plant (27.18%). High estimates of heritability were recorded for different characters viz., average fruit weight (98.6%) followed by total soluble solids (97.8%), total sugars (97.7%) and days to anthesis of first pistillate flowers (97.2%). The parameters which observed were found to be very high estimate value of genetic advance in per cent of mean of (60.14%) average fruit weight (60.14%) followed by titratable acidity (53.73%), number of branches per plant (53.47%), total soluble solids (52.81%) and marketable fruit yield per plant (47.87%).

The market for small fruits (grapes, blueberries, strawberries, and raspberries) is valued at more than CAD100 million per year in Quebec, Canada. Wood-based biochar is an amendment that improves soil quality, which may boost small fruit growth and production. The objective of this research was to determine if wood-based biochar could increase the yield and quality of grape, blueberry, strawberry, and raspberry in southern Quebec. We evaluated the fruit yield as well as the quality parameters like average fruit weight, fruit firmness, color, juice pH, total soluble solids, total phenolic content, and antioxidant activity. Field trials were established on commercial farms with grape, blueberry, strawberry, and raspberry production systems in plots that received wood-based biochar and no biochar in spring (April to May). Small fruits were harvested at their ripening stage for yield and quality evaluation in fall (July to October). Biochar application did not improve yield and quality parameters of small fruits except it gave a marginal higher yield of grape (3.7 vs. 4.4 t ha-1, P = 0.08) and a higher average fruit weight of strawberry (11.9 vs. 13.2 g, P < 0.05). There was no difference in the quality of the fruit from biochar-amended and control plots in the first year of biochar application, possibly because the quality parameters are affected more by weather conditions, handling, and storage than by soil quality. This work suggests that wood-based biochar (<5 t ha-1) has a limited first-year impact on small fruit yield and quality in southern Quebec, Canada.

Impact of Grafting on Watermelon Growth, Fruit Yield and QualityGrafting is an alternative approach to reduce crop damage resulting from soil-borne pathogens and increases plant abiotic stress tolerance, which in turn increases crop production. The purpose of this study was to determine whether grafting could improve plant growth and fruit quality of watermelon through monitoring the changes induced by different rootstock-scion combinations. Watermelon (Citrullus lanatus) cv. Aswan F1was grafted into five rootstocks (Nun 6001 F1, Strongtosa F1, Tetsukabuto F1, Ferro F1and Shintoza F1) hybrids betweenCucurbita maximaandCucurbita moschata.Highest vegetative growth and fruit yield were obtained by ‘Nun 6001 F1’ as a rootstock using the tongue approach method. Grafting reduced significantly sex ratio by reducing the number of male flowers. Grafting increased significantly lycopene content in fruit flesh by 57% over the control treatment, but did not affect soluble solids content (SSC). One third of the control non-grafted plants died andFusarium oxysporumwas isolated as the responsible pathogen. These results indicate that grafting watermelon onto specific rootstock influences growth, productivity, and quality of the fruit as well as disease resistance. Grafting can be suggested as an alternative method to control ofFusariumwilt in watermelon production.

Evolved in South Africa and released to market in 2009, the ‘African Rose’ plum has been introduced and grown under the Egyptian semi-arid conditions since 2010. Within that time, this cultivar has faced significant fruit quality issues, mainly poor color and low total soluble solids (TSS). Several trials using foliarly applied growth regulators have been conducted, but with little conspicuous results on fruit yield and quality. There is very limited information about the relationship between irrigation regime and fruit quality for this cultivar. Therefore, a field experiment was conducted to study the effect of deficit irrigation on the quality of the ‘African Rose’ plum during the 2019 and 2020 seasons. Five-year-old hedge growing trees were subjected to three deficit irrigation regimes: 100% (control), 80%, and 60% of the crop evapotranspiration (ETc) after the pit hardening stage until the end of the harvest season (May to June period) were evaluated. Results indicated that deficit irrigation positively enhanced the levels of abscisic acid (ABA), total phenols, and anthocyanins with improved fruit TSS and maturity index, although fruit yield, acidity, size, and firmness were decreased. Deficit irrigation could be suggested as a sustainable novel solution to improve the fruit quality of the ‘African Rose’ plum grown under the semi-arid conditions of Egypt. Although the total yield and some quality characteristics were not improved, the early harvested fruit with enhanced color and taste could be a good start for additional research to solve other quality-related issues under such conditions.
