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 Mechanizing the harvest of Jalapeño pepper involves changes in the production system. Spacings between plants in rows (10 to 40 cm; 60 cm fixed between rows) were evaluated in relation to plant architecture, productivity and fruit quality of cultivar BRS Sarakura during three years, in a randomized complete block design with five replicates. Productivity (41.9 to 78.8 t ha-1) and plant height (40.1 to 47.3 cm) responded linearly to density; on the other hand, productivity per plant responded negatively (0.48 to 1.04 kg plant-1). The stem first bifurcation height was little influenced. Fruit chemical analyses were carried out in the second year of the experiment; spacing significantly influenced pH (5.36 to 4.84), total titratable acidity (TTA) (0.48 to 0.36%) and total soluble solids (TSS)/TTA ratio (11.5 to 15.6); no influence on TSS (5.65%) was noticed, though. The increase of plant population provided an increase in productivity without affecting fruit quality; the highest height of the first bifurcation achieved may not be enough to enable mechanized harvesting of the cultivar BRS Sarakura.

Fig Tree

The objective of this work was to verify the influence of planting density on productivity and fruit quality of the fig tree. The design was used in three blocks, the plants of the cultivar Roxo de Valinhos were submitted to three planting spacings: 5 x 0.5 m; 5 x 1.0 m; and 5 x 1.5 m. The evaluated characteristics were: length of branches; average weekly growth of branches; fruit size; average fruit weight;soluble solids (°Brix); yield of mature fruits; productivity of green fruits; accumulated productivity; and dry mass of fruits.The length of the branches was not influenced by planting spacing, the plants conducted at lower densities presented higher productivity, both of green fruits and accumulated productivity.Plants submitted to lower planting density produced fruits with higher dry matter, but these were smaller in size, but without significant difference for those submitted to lower density. It wasconcluded that productivity is directly affected by fig planting density, but not all the qualitative aspects of the fruits were affected.

The paper examines the influence of three clonal rootstocks ('Pixy', 'Fereley' and 'St. Julien A') along with seedlings of Myrobalan (control) on the growth, yield and fruit quality of the plum cultivar 'Cacanska Rana'. Research was conducted in the area of the Belgrade Danube basin for the six-year period (2013-2018). In comparison to control, all three clonal rootstocks have shown a significant effect on the decrease of vigor expressed as a trunk cross-sectional area. The lowest vigor was found in trees on the 'Pixy' rootstock, then on 'Fereley' and 'St. Julien A' rootstocks. Regarding the rootstocks 'Fereley' and 'St. Julien A', significantly higher fruit set and yields were achieved in comparison to control. Clonal rootstocks induced an increase in the yield per hectare ranging from 72% to 93% compared to Myrobalan. The highest yield efficiency was found in the trees on the 'Fereley' rootstock, followed by the yields observed in the trees on the 'Pixy' and 'St. Julien A' rootstocks. Significantly higher fruit weight compared to control was obtained in the trees on the 'Fereley' rootstock. Rootstocks did not show any significant effect on the soluble solids and total acid contents of the fruit. Based on the results obtained, it can be concluded that all three clonal rootstocks showed better results than Myrobalan, and can be recommended for establishing intensive plum plantations with higher planting density. The best results in terms of yield and fruit quality were obtained with the 'Fereley' rootstock.

West Indian cherry stands out among the fruits cultivated for the pharmacological and alimentary importance, but its quality can be affected by irrigation water salinity and fertilization management. In this context, this research aimed to study the effect of irrigation water of different salinities and combinations of nitrogen and potassium fertilization on the physical and physico-chemical quality of bioactive compounds in West Indian cherry fruits. The experiment was carried out in the field, using lysimeters of 60 L, in the Experimental Area of the Centro de Ciências e Tecnologia Agroalimentar (CCTA) of Universidade Federal de Campina Grande (UFCG), Pombal, PB, in a randomized block design, with treatments arranged in a 5 x 4 factorial scheme, referring to five irrigation water salinities (ECw): 0.3, 1.3, 2.3, 3.3 and 4.3 dS m-1 and four combinations (C) of doses of nitrogen (N) and potassium (K2O): C1 = 70% N + 50% K2O; C2 = 100% N + 75% K2O; C3 = 130% N + 100% K2O and C4 = 160% N + 125% K2O, of the recommended dose for West Indian cherry, with three replicates and one plant per plot consisting of a lysimeter. The cv. Flor Branca grafted on cv. Junco was used in the study. The increase in salinity of irrigation water reduced the size, weight and vitamin C content of the fruits, but, the combinations of N and K fertilization did not affect fruit shape and the content of anthocyanin, carotenoids, pH, titratable acidity, total soluble solids and fruit flavor. Fertilization combinations consisting of C1 and C2 treatments promoted the largest fruit size under irrigation with ECw of up to 1.3 dS m-1 and greater mass accumulation. Fertilization doses above C2 combinations negatively affected fruit quality.

ABSTRACT Obtaining a high yield of good quality fruits is one of the main challenges of the tomato crop. The enhancement in plant density promotes a reduction in the fruit fresh mass and an increase the yield per area. On the other hand, commercialization parameters take into account number and fresh mass of fruits. This study aimed at evaluating the yield and fruit quality of indeterminate growth hybrid tomato (Rebeca), cultivated in a hydroponic system, with different planting densities and number of bunches per plant. The experiment was conducted under greenhouse conditions, in a sub-irrigation system containing expanded clay as substrate. A split-plot randomized block design, with three replications, was used. In the plots, four planting densities (11.1 plants m-2, 8.3 plants m-2, 6.6 plants m-2 and 5.5 plants m-2) were allocated and, in the subplots, the number of bunches per plant (one or two). The total yield was influenced by the interaction planting density x number of bunches per plant. The treatment that allowed the highest yield was 11.1 plants m-2 with two bunches, with 22.61 kg m-2 or 226.1 t ha-1, in a crop cycle of 134 days. The observed variations for the nutrient contents of leaves and fruits of tomato plants with one or two bunches, at densities of 5.5-11.1 plants m-2, do not compromise the fruit quality nor influence the production of tradable fruits, using the hydroponic system.

The Tropics

The issue of low tomato production in the tropics like Ghana has been a long-standing challenge. The advent of greenhouse technology has not significantly improved the yield of tomato compared to Japan and the Netherlands. Immediate technological interventions are needed. Through hydroponics, the low-node order pinching at a high-density planting system has been recommended in some studies. This system was intended to be established in Ghana, and it would be expected to improve the yield and fruit quality of tomato. In effect, a study was carried out in the greenhouse, at Chiba University using this system. A tropical tomato cultivar (Jaguar) was evaluated with Momotaro York at 3.8 m s2 and pinched at the fourth truss. Data collected were water and nutrient use efficiencies, plant growth rate, dry matter partitioning, and fruit yield and quality, as well as some physiological characteristics. The experiment was laid out in a randomized complete block design with three replications. Results showed that Jaguar cultivar was two times more efficient in water and nutrient use than Momotaro York at first harvest. Root tissue density recorded in Jaguar was significantly lower compared to Momotaro York. The net assimilation rate (NAR) recorded was markedly higher in Jaguar than Momotaro York at last harvest. All the physiological attributes recorded in both cultivars were not significantly different. Plant dry mass (DM) recorded was similar in the two cultivars; however, the DM partitioned to fruits was 55% in Jaguar compared to 46.5% DM for Momotaro York. Fruit yield per area did not differ in the two cultivars. Fruit yields of 28.8 and 30 kg m−2 per year were recorded in Jaguar and Momotaro York, respectively. In comparison, this yield result is 1.2–1.25 times less and 14.4–15 times higher than current tomato yields recorded in Japan (greenhouse) and Ghana, respectively. Fruit quality, in terms of total soluble solids recorded in Jaguar cultivar being 5.4 %Brix, was within the 3.5–5.6 %Brix recorded in Ghana. This system could effectively enhance the yield and quality of tomato in the tropics as well as economising on the use of resources.

[email protected]   1 RESUMO A qualidade do tomate está diretamente relacionada com a qualidade da água utilizada na irrigação e com o suprimento adequado de nutrientes, principalmente o potássio e o cálcio. Este trabalho foi desenvolvido em ambiente protegido na UFERSA, em Mossoró, RN, com o objetivo avaliar a qualidade do tomate em função de diferentes relações iônicas de potássio e cálcio (K+/Ca2+), sendo: F1=1,5:1; F2=1,25:1; F3=1:1; F4=1:1,25 e F5=1:1,5 e quatro níveis de salinidade da água de irrigação (S1-0,5; S2-2,0; S3-3,5 e S4-5,0 dS m-1). O delineamento experimental utilizado foi em blocos casualizados, em esquema fatorial 5 x 4, totalizando 20 tratamentos, com quatro repetições. A relação K+/Ca2+=1:1 correspondente a concentração desses nutrientes recomendada para a cultura em cultivo de tomateiro hidropônico. Foram avaliadas as variáveis relacionadas a qualidade de frutos (sólidos solúveis, vitamina C, acidez titulável, pH e relação AT/SS). O uso de água com salinidade entre 2,0 e 3,5 dS m-1 aumenta a qualidade do tomate pelo aumento da razão SS/AT. As fertirrigações com maiores concentrações de K favorecem a qualidade dos frutos para salinidades até 3,5 dS m-1, mas não afetam a qualidade de tomate na salinidade 5,0 dS m-1. Palavras-chave: solanáceas, uso de águas salinas, potássio, cálcio  PAIVA, F.

PQUALITY OF TOMATO AS FUNCTION OF IRRIGATION WATER SALINITY AND K/CA RATIO IN FERTIGATION  2 ABSTRACT The quality of tomato is directly related to the quality of the water used in irrigation and to the adequate supply of nutrients, mainly potassium and calcium. The objective of this work was to evaluate the quality of tomatoes as a function of the different ionic ratios of potassium and calcium (K+/ Ca2+), with: F1 = 1.5:1; F2 = 1.25:1; F3 = 1: 1; F4 = 1:1.25 and F5 = 1:1.5 and four irrigation water salinity levels (S1-0.5, S2-2.0, S3-3.5 and S4-5.0 dS m-1). The experimental design was a randomized complete block design in a 5 x 4 factorial scheme, totaling 20 treatments, with four replications. The K+/Ca2+ ratio = 1:1 corresponds to the concentration of these nutrients recommended for cultivation in a hydroponic tomato crop. The variables related to fruit quality (soluble solids, Vitamin C, titratable acidity, pH and AT / SS ratio) were evaluated. The use of water with salinity between 2.0 and 3.5 dS m-1 increases tomato quality by increasing the SS/AT ratio. Fertigation with higher concentrations of K favor fruit quality at salinity up to 3.5 dS m-1, but do not affect tomato quality at 5.0 dS m-1 salinity. Keywords: solanaceae, use of salt water, potassium, calcium
