Abstract The objective of this study was to evaluate the influence of macronutrient and boron deficiencies on physico-chemical characteristics of pineapple fruits, ‘Vitoria’ cultivar. The experimental design was a randomized complete block with eight treatments (complete solution, -N, -P, -K, -Ca, -Mg, -S and -B) and six replicates. The experiment was conducted from October 2016 to March 2018, and the variables evaluated were: fresh fruit and crown mass, fruit diameter, fruit and crown length, juice volume and mass, titratable acidity (TA), soluble solids (SS), vitamin C, juice pH and SS/TA ratio. All treatments with nutrient deficiency reduced the fresh fruit mass. In treatments -N and -Ca there was a reduction of 41.9 and 35.3%, respectively, in the crown fresh mass. Fruits diameter under N, K and Mg deficiency was lower, fruit length, soluble solids and juice pH were lower in treatment with N deficiency. Isolated deficiencies of each of the macronutrients and B reduced the mass of the whole fruit and the crownless fruit. The nutrient that most limited the size and quality of ‘Vitoria’ pineapple fruit was nitrogen.

ABSTRACT: Type of fertilizer and doses used are factors that influence the quality of pineapple fruit. This study aimed to evaluate the physico-chemical and sensorial quality of organically grown ‘Pérola’ pineapple and recommend the effective dose for best fruit quality, especially regarding sensorial acceptance. Effect of doses of 10, 20, 30, 40 and 50 t ha-1 of “bokashi” organic fertilizer on color, weight, pH, titratable acidity, soluble solids, soluble solids/titratable acidity ratio (SS/TA), vitamin C content, sensory acceptance and purchase intention was evaluated. Increasing doses of bokashi positively influenced weight and titratable acidity of the fruits and negatively affected the SS/TA ratio. Fruits produced with doses between 20t ha-1 and 40t ha-1. had good sensorial acceptance and were considered to have ideal acidity, sweetness and texture by most consumers. The authors recommend using 20 t ha-1 of bokashi, as this dose promotes the production of high quality fruits, with satisfactory SS/TA ratio and high sensorial acceptance.

Pineapple is commonly planted in monoculture systems. It is a long-cycle crop that takes time to monetize, which hinders its cropping by small farmers. The objective of this work was to evaluate the production and quality of pineapple with short-cycle crops, at the beginning of the growing period, as an alternative for family farming in the state of Tocantins. The experimental design was randomized complete block with three treatments and four replications. The pineapple was intercropped with rice and cowpea. The treatments consisted of T1: pineapple + rice; T2: pineapple + cowpea and T3: pineapple in monoculture. The evaluated variables of the pineapple fruit were pH, soluble solids, titratable acidity, yield, fruit mass, fruit length with crown, fruit length without crown and fruit circumference. For the rice and cowpea, the yield and the Area Equivalence Index (AEI) were determined. The cropping system did not influence the pineapple fruits quality. The pineapple yielded less. Cowpea yielded more when intercropped with pineapple. The AEI of the pineapple + rice intercropping was 2.07, being feasible for increasing the use of the area by 100%. The AEI of the pineapple + cowpea intercropping was 2.48, being feasible as it increased the use of the area by 148%. The results obtained showed that it is possible to intercrop pineapple with rice or cowpea at the beginning of pineapple cultivation, and it can be a viable alternative for family farming.

Abstract Potassium is a mineral nutrient that affects the growth and quality of pineapple fruits. This study aimed to evaluate the quality of ‘Vitória’ pineapple fruits submitted to application of potassium doses. The experiment was carried out from May 2017 to November 2018, in the municipality of São Francisco do Itabapoana (RJ), Brazil. The design was randomized blocks, with four replicates. Treatments were five K2O doses: 0; 6; 12; 18 and 24 g plant-1, applied as KCl, split into two applications after flower induction. Fruit and crown fresh masses, fruit and crown diameters, fruit and crown lengths, titratable acidity, soluble solids, vitamin C, juice pH and soluble solids/titratable acidity ratio were evaluated. Potassium fertilization promoted greater fruit length, diameter and mass. Titratable acidity, soluble solids and vitamin C values increased linearly as a function of potassium doses. Potassium fertilization improves the quality of ‘Vitória’ pineapple fruits under field conditions.

Bell Peppers

The bell pepper presents alterations in its composition and its properties with the process of senescence during ripening. These composition and textual factors are part of the quality of the fruit and therefore of the selection. This permits the correct knowledge of the factors necessary for post-harvest measures, so that they can be adequately applied. The aim of this study is to analyze the 'Zarco HS' yellow pepper at various levels of ripeness taking into account its physico-chemical properties (titratable acidity, pH, total soluble solids, water content, and ascorbic acid), in order to understand this behavior during the ripening process. Bell peppers were separated based on their yellow percentage, which varied from 0% to 100%, and for each percentage five fruits were chosen as replicates. They were compared to 0%, 25%, 50%, 75% and 100% levels of ripening, due to the difficulty of the methodology in identifying the smaller differences between coloring. The 'Zarco HS' yellow bell pepper presents greater levels of soluble solids and lower levels of malic acid as the percentage of external yellow coloring increases. The yellow bell peppers, especially when totally yellow, represent an important source of vitamin C.

Pineapple is considered as one of the most wanted tropical fruits and it is widely taken for fresh consumption as well as their flesh and juice are used for preparation of different product in Agro-processing industries. For such industrial processes, it is important to know the information of characteristics changes of pineapple during day after storage. Four varieties of pineapple were collected from different areas of Bangladesh named Honey Queen (H.Q), Giant Kew (G.K), Asshini and Ghorasal. Some Physico-chemical properties (weight loss, moisture content, ash and edible portion, pH, TSS, titrable acidity (TA), total sugar, reducing sugar) biochemical properties (ascorbic acid) and sensorial attributes (color, odor, firmness, appearances, sweetness and overall acceptability) of pineapple juice were studied during day after storage. This study examined the Comparison of different varieties of pineapple fruit characteristics and sensory quality of the pineapple fruits during storage. It was shown that there was a significant changes between the storage periods in relation to different varieties of fruits. The firmness of pineapple fruits were in outside and inside to be 0.21 to 0.27 N/m2 and 0.06 to 0.10 N/m2, respectively. The pH values of different varieties were found to be in the range of 4.30 to 4.36. The highest and lowest sweetness index were estimated to be 36.30 and 22.15 for Honey Queen and Asshini respectively. The highest and lowest magnitude of sugar contents of four pineapple varieties were found to be in the range of 14.16 to 15.8 mg/100g.The average TSS values were found to be 15.12%, 12.33%, 13.14% and 12.95% for H.Q., G.K., Asshini and Ghorashal, respectively. The comparative study indicated the characteristics of different varieties of pineapple changes during after storage.Res. Agric., Livest. Fish.2(3): 395-410, December 2015

ABSTRACTThe production of high quality fruits is a necessary factor for the adaptation and production of plant species with economic viability. Thus, an experiment was conducted from July 2012 to January 2013 to evaluate the fruit quality of the ‘Eva’ and ‘Princesa’ apple cultivars as a function of nitrogen fertilization in Petrolina, PE, Brazil. The experimental design consisted of randomized blocks, with treatments distributed in a factorial arrangement 2 x 4, corresponding to apple cultivars (Eva and Princesa) and nitrogen doses (40; 80; 120 and 160 kg of N ha-1), with four replications and three plants in each plot. The fruit characteristics, such as fruit mass, skin color (luminosity, chromaticity, and colour angle), size (width and length), pulp firmness, titratable acidity (TA), soluble solids (SS) and the SS/TA ratio, were recorded. Nitrogen doses do not affect fruit quality of studied apple cultivars. The fruit quality attributes are different between apple cultivars: fruit firmness, SS/TA ratio, fruit mass and fruit diameter are superior for Princesa cultivar, while the fruit length for Eva cultivar is superior.

Yield And Quality

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.

Cherry Tomatoes

Hydroponic cultivation of vegetables avoids problems with soil-borne plant pathogens and may allow higher yield. In arid climates and particularly on islands, high concentrations of sodium chloride can be present in the groundwater. For instance, in many sites of Malta, the groundwater contains more than 10 mM sodium chloride. Here we investigated the effects of sodium chloride at levels typically found in Malta on yield, physiology and fruit quality of tomato, the economically most important vegetable. We selected cherry tomatoes since their production is attractive due to their high marketing value. While the yield declined at higher salinity levels tested (17 and 34 mM), the quality increased significantly as indicated by higher total soluble solids and fructose and glucose levels. The type of substrate—coco peat, perlite or Rockwool—had only minor effects. Although the concentration of citric acid and malic acid remained unaffected, the pH dropped by approximately 0.1 unit and the titratable acidity increased slightly. This might be explained by a high uptake of chloride but a lower increase of the sodium content and a reduced potassium level in the fruits, shifting the equilibrium of the organic acids more to their protonated forms. Proline increased significantly, while the level of glutamic acid, which is crucial for the taste, remained unchanged. Our results show that cherry tomatoes can be cultivated in nutrient solutions prepared with salt-containing groundwater, as found in Malta. The yield declined to some extent but the quality of the produced fruits was higher compared to cultivation in salt-free media.
