The phyto-technical management of crops, such as the conduction system, spatial arrangement of plants and mineral and organic fertilization are pre-harvest agronomic factors that can alter fruit quality. Therefore, this research was developed to evaluate physico-chemical attributes of yellow passion fruit as a function of population arrangement and organomineral fertilization. The experiment was carried in Entisol with free-sand texture under tropical climate with dry summer. The treatments were obtained from the combination of doses of nitrogen (92, 119, 183, 248 and 275 kg ha-1) and soil organic matter (1.3, 1.8, 2.9, 4.0 and 4.5%), through Central Box Compound, plus four additional treatments to study the effect of the number of plants per pit. The evaluations were carried on seven and ten months after the transplanting of the seedlings. A randomized block design with three replications was used. The fruits were harvested at the beginning of the yellowing of the bark and evaluated in the pulp: pH, total titratable acidity (TTA), total soluble solids (TSS), reducing sugars, non-reducing sugars and total sugars, ascorbic acid, TSS/TTA ratio, electrical conductivity and humidity. The harvesting season changed the physico-chemical properties of the passion fruit pulp and interfered with the effects of plant management and fertilization on the quality of passion fruit. For the production of the best quality passion fruit we may cultivate one, two or three plants per pit. With three plants per pit it is recommended to apply 180 kg ha-1 of nitrogen annually and raise the soil organic matter to 4%.

The study aimed to develop a non-dairy-based probiotic-supplemented product using an underutilized crop in the Philippines such as the yellow passion fruit (Passiflora edulis f. flavicarpa Deg.). The physico-chemical properties (moisture content, water activity, pH, and total soluble solids), probiotics stability at different storage temperatures (4°C, 25°C, and 37°C), and the sensory characteristics of Lactobacillus plantarum S20-supplemented passion fruit juice powder was evaluated. Passion fruit juice powder and L. plantarum S20 were first prepared using low-temperature spray drying utilizing maltodextrin as a carrier, with yield as 42.97% and 21.17%, respectively. Spray drying of probiotics culture also resulted in 42.68% log survivability. The formulated juice powder had a final moisture content of 1.729±0.38% and water activity of 0.398±0.0051, and with recommended dilution with water, had a final pH and total soluble solids of 3.40±0.10 and 12.00±0.00° Brix, respectively. Results also showed that storage of the formulated juice powder at 4°C yielded the highest probiotic stability, maintaining a viable log count of 4.27 per g, while storage at 37°C showed no microbial growth. Sensory evaluation of probioticsupplemented passion fruit juice against a non-probiotic-supplemented one revealed significant difference in terms of color, sweetness, and sourness, while no significant difference was observed in terms of aroma, mouthfeel, and general acceptability.

Saccharin sorghum (Sorghum bicolor L. Moench) is a promising energy crop due to the storage of fermentable sugars in the stems, which are easily converted into ethanol. The objective of this study was to evaluate the influence of the application of phosphorus and Ethephon on the development, productivity of sorghum and technological quality of saccharin sorghum. The experiment was conducted at Teaching and Research Farm, located in Selviria-MS. The experimental design was a randomized complete block design with a 5x4 double factorial design, with five doses of phosphorus (0, 40, 80, 120, 160 kg ha-1 P2O5) and four doses of Ethephon (0, 330, 660, 1,320 mL ha-1) with four replicates. The variables analyzed were: plant height, stem diameter, leaf number, stand at 15 and 60 days after Ethephon application (D.A.A), fresh and dry biomass volume and yield. In addition, the following technological variables were evaluated: soluble solids content (BRIX%); sucrose content (POL%); reducing sugars (RS%); total reducing sugars (TRS%); fiber (%); purity (%) and humidity. The doses of P2O5 did not influence the productivity, but increased the stem diameter. Ethephon doses did not influence the yield of sorghum, but improved the technological quality of the extracted juice.

Aims: The objective was to determine the influence of the onion harvest time "Baia Periforme" on post-harvest quality of the bulbs during storage. Study Design: The experiment was conducted in a randomized block design with three treatments, six replicates with two bulbs each. Place and Duration of Study: Departamento de Fitotecnia, Universidade Federal de Viçosa, between June 2017 and July 2018. Methodology: Seedlings, 20 days old, were transplanted into 20 cm spacing between rows and 10 cm between plants. The bulbs were harvested 120 days after transplanting with manual tipping of the pseudo-stem (T1), with 50 (T2) or 75% (T3) of the bulbs popped. The soluble sugars (SS), non-reducing sugars (NRS), reducing sugars (RS), total soluble solids (TSS), titratable acidity of phenolic compounds and alinase activity was determined every 30 days for 90 days. Results: The content of SS, TSS, phenolic compounds and alinase activity increased in the onions of T2, resulting in more sweet and pungent bulbs due to the higher content of acidity and phenolic compounds. Conclusion: The post-harvest quality of onion bulbs "Baia Periforme" was maintained when they were harvested with 50% of bulbs popped.

Cocoa is a plantation commodity that requires fermentation to improve the quality of flavor and aroma. Research on changes in physical and chemical properties during the spontaneous fermentation process of fresh cocoa beans for weight scales of 20, 40 and 60 kg have been carried out. This study aims to obtain information as an indicator of the success rate of the fermentation process of fresh cocoa beans, both on a small and large scale. The fermentation process lasts for 6 days with stirring starting on the second day until the sixth day, with an interval of 24 hours. The study design uses a randomized block design method (RBD) with two factors, namely the weight scale of seeds per box and fermentation time with three replications. The data obtained were analyzed qualitatively and quantitatively. Based on the observed parameter indicators, namely temperature, pH and total acid, there was no significant difference in the profile of the physico-chemical properties during the fermentation process between the three weight scale levels. The physico-chemical condition shows a straight relationship with the quality of fermented cocoa beans, in accordance with the results of the cut test.

Precision farming involves the collection of detailed information about the characteristics of agricultural operations. Electro-conductivity (EC) of soil is one of the tests easier and less costly for agriculture, which can be performed today. Electro-conductivity (EC) is the ability of a material to transmit (conduct) an electrical current and is usually expressed in miliSiemens / meter (MS / m). Electro-conductivity (EC) of soil is a measurand that characterizes many soil properties which affect the productivity of crops. These include the water content, soil texture, soil organic matter (OM), depth to clay layer, the capacity of cation exchange (CEC), salinity, calcium, magnesium. Measurements of electro-conductivity (EC) of soil can add value to agricultural operations if they can be used to help explain variations in agricultural production. Article shows electro-conductivity maps models of the prepared soil in different locations in Romania and electro-conductivity correlation with the physico-chemical properties of these soils

An investigation was conducted to assess the effect of fertilizers, Azospirillum and compost (kitchen waste manure) on chilli (Capsicum annum var. frutescence) cv. Pusa Jwala at Babasaheb Bhimrao Ambedkar University, Lucknow (U.P.) during winter season of 2016-17. The twelve treatments were evaluated in a randomized block design with three replications. Results showed that the highest fresh weight of fruits per plant (575.73g), highest fruit yield (9212 g plot-1 and 4.26 t ha-1) was recorded with 50% RDF + kitchen waste manure (25 and 50 days after transplanting)] followed by RDF 50% + Azospirillum (soil application at transplanting). However, the quality characters in terms of total soluble solids (7.4 %), ascorbic acid (116.67mg/ 100 g fruit), total sugars (2.5 %), reducing sugars (1.7 %) and non-reducing sugars (0.8 %) of fruits were observed better with Azospirillum treatment along with RDF i.e. RDF 50% + Azospirillum (soil application at transplanting)]. It was also seen that combined effect of RDF and organic manures proved superior to RDF (100%) sole application in respect of yield and quality of fruits. The lowest values of yield and quality parameters were recorded in control treatment.

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.

The present investigation was carried out to observe the effect of potassium on different parameters of apple in temperate conditions. Randomized block design experiment was adapted for an orchard of 15 years old with collection of soil samples and their analysis for  physico-chemical properties under different treatments with fixed quantity of urea (1500g/tree), DAP (750g/tree) and potassium through MOP, K2SO4 and K-Schoenite (2500g/tree) in three, one and two split applications, respectively. The first application of recommended quantity of fertilizers was applied three weeks before expected bloom, Second three weeks after fruit set and third application at the end of July. Sample collection was done in the month of September followed by analysis for different parameters and results revealed that application of potassium through MOP @ 2500g/tree with two foliar applications of MOP @ 1.5 % including vermicompost @ 5kg/tree (T4) improved soil physical conditions, nutrient availability, fruit yield and quality of apple. The combined effect of chemical fertilizer, two sprays and organic fertilizer (vermicompost) showed significantly (P?0.05) higher results of nitrogen, phosphorous, potassium magnesium and sulphur but low calcium than other vermicompost added treatments. The work concluded that different potassium sources can have great impact on yield and quality of apple and respond to level of concentrations or dose as applied in current study with different split.
