This investigation was conducted to determine the effect of organic fertilizers on the content of chlorophyll a, chlorophyll b, antioxidant activity, crude fibre, and zinc in two onion cultivars, Stuttgarter Riesen and Rote Laaer, during 2016, 2017, and 2018. In this research, the following treatments were used: B-Stimul (contains Azospirillum Tarrand et al., Azotobacter Beij., Bacillus Cohn, Chlorella vulgaris Beij., and Herbaspirillum Baldani et al.), EkoBooster 2 (contains biostimulators and mineral salts of nitrogen, phosphorus, and potassium) and Vermifit A (extract of compost of Californian earthworm). The results showed that the application of biofertilizers to onion resulted in the highest chlorophyll b content in 2017 in Stuttgarter Riesen. EkoBooster 2 positively affected crude fibre content in both cultivars, but only in 2016. Antioxidant activity was not significantly affected by the interaction of experimental factors. The application of the biostimulating fertilizers can have a positive impact on the quality parameters of onion, but the kind of fertilizer must be suited to seasonal conditions and the cultivar.

A field trial was conducted to determine the nutritive value of eight Slovak and Czech red clover varieties and to quantify the effects of variety, cut and year on red clover forage quality. The differences between forage quality of the evaluated red clover varieties were significant for protein supplied when energy is limited in the rumen (PDIE), intestinal digestibility of rumen non-degraded protein (dsi), net energy values and ash content (P < 0.01). The achieved results show that the surpassing forage quality was given by diploid Viglana variety with high protein and energy values. The forage of tetraploid varieties Javorina and Dolina was outstanding in protein content, but had the lowest energy values. The nutritive value was significantly affected by cut. The first cut provided forage with a significantly lower (P < 0.01) crude protein (CP) content, CP digestibility, degradability of CP (degNL), protein supplied when nitrogen is limited in rumen (PDIN), PDIE and with a significantly higher crude fibre content and energy values (P < 0.01). The differences between varieties were more pronounced in the second and in the third cut. Significantly higher (P < 0.01) PDIE, PDIN, degNL, net energy values and ash contents were found in the first production year.

The article is devoted to the development of a technology for obtaining organic fertilizers from poultry waste based on biocatalytic processes. Currently, many poultry farms have become sources of environmental pollution, thereby causing serious environmental problems and economic and social damage. The problem of reliable protection of the natural environment from pollution by bird droppings is currently relevant. In the area of operation of large poultry farms, air pollution by microorganisms, dust, foul-smelling organic compounds, which are decomposition products of organic waste, as well as nitrogen, sulfur, and carbon oxides, is possible. Bird droppings contain acids, nitrogen, phosphorus and potassium, heavy metals. The content of nitrogen, phosphorus and potassium changes dramatically depending on the quantity and quality of the feed. Humic substances isolated from brown coal have a sufficiently high sorption activity and are used as cheap sorbents for solving a number of environmental problems in industry. These studies are aimed at minimizing the main disadvantage of the anaerobic digestion process, the low reaction rate, which leads to the need to create large-volume bioreactors. On the basis of the research carried out, a technology has been developed for obtaining organic fertilizers from poultry waste by the method of anaerobic fermentation of chicken manure with humidity at a temperature of 27 °C - 50 °C with the addition of sodium humate. The resulting fertilizer is intended for use in agricultural production, horticulture, floriculture, forestry, municipalities, in household plots in order to increase the yield and quality of crop production. For the developed technology, an application has been submitted for obtaining a Patent for the invention of the Republic of Kazakhstan «Method for producing organic fertilizers» (priority No. 2021-22818, dated July 13, 2021). The invention allows to significantly reduce the time of fermentation, to enrich the product with organic and mineral products contained in sodium humate, to convert the salts of heavy metals into an insoluble state, to improve the environmental friendliness of the method.

To improve the antioxidant activity (AA), digestibility, and quality of fiber-rich dumpling wrappers, potato, okara, and konjac flours were added to wheat flour. The contents of these additional ingredients in the dumpling wrapper were optimized using the response surface methodology and the synthetic evaluation method. The dietary fiber content (DFC) and AA of blend flours and the optimized cooking time (OCT), cooking loss (CL), hardness, chewiness, firmness, color, and sensory evaluation (SE) of dumpling wrappers were evaluated as response quality parameters. The optimized flour was identified containing 17.5 g of potato flour, 8.5 g of okara flour, and 1.2 g of konjac flour per 100 g of blend flour, which resulted in a higher synthetic evaluation index value (0.71 compared with 0.68 for wheat flour). The qualities of the optimized flour dumpling wrappers were compared with those of wheat flour dumpling wrappers to verify the practicality of the optimized flour. The results showed that the optimized flour showed better comprehensive qualities, especially regarding DFC (9.59%, fourfold higher than that of wheat flour) and AA. Furthermore, the predicted glycemic index (GI) of the optimized flour (74.93%) was lower than that of the wheat flour (81.47%). Overall, the addition of potato, okara, and konjac flours can significantly (P<0.05) improve DFC, AA, and digestibility of wheat flour. The optimized flour not only maintains excellent dumpling wrapper quality but also increases the utilization of potato and okara flours, which has great potential for industrial applications.

Swiss chard (Beta vulgaris L. var. cicla) is a popular vegetable because it is nutritious, robust, easy to grow. It requires regular applications of nitrogen, which causes accumulation of oxalates and nitrates within the plant. Oxalates and nitrates are known health hazards but the use of organic fertilizers have been shown to reduce their accumulation and to promote accumulation of beneficial phytochemicals. We therefore determined the effect vermicompost (VC), Tithonia diversifolia green manure (Tithonia) and urea on the quality of Swiss chard. The experiment was laid out in a Randomised Complete Block Design (RCBD) replicated three times with thirteen treatments. Leaf nutrient elements, TSS, polyohenols, Vitamin C and antioxidants were determined using standard procedures. Treatment effects were significant only for aluminum, phosphorus and calcium. The values were highest on VC 50 kg N ha-1 and Urea 50 kg N ha-1, Tithonia 50 kg N ha-1 + Urea 50 kg N ha-1, and VC 50 kg N ha-1, and VC 100 kg N ha-1 for aluminum, phosphorus and calcium, respectively. Lowest response was reported on Tithonia 50 kg N ha-1, control and Tithonia 50 kg N ha-1 + Urea 50 kg N ha-1 for aluminum, phosphorus and calcium, respectively. The treatments significantly influenced the percentage of polyphenols, vitamin C and the antioxidant capacity while no significance was reported for total soluble solutes. The polyphenols and vitamin C content were highest on Tithonia 100 kg N ha-1 and control, respectively. Low polyphenol and vitamin C contents were recorded on VC 50 kg N ha-1 and VC 100 kg N ha-1, respectively. A similar trend was observed for antioxidant activity since a positive correlation was observed between the polyphenols and vitamin C and the antioxidant activity. Tithonia green manure improves Swiss chard quality.

Quality of minimally processed jackfruit bulb was evaluated during storage at different storage times, temperatures, and types of packaging. The jackfruit pulps were first dried at 45 °C, stored in polypropylene plastics, zipper bags and plastic boxes. Quality parameters were evaluated every 5 days and based on phytochemical changes such as vitamin C, polyphenol, and antioxidant activity. Results revealed that polypropylene plastics were the best packaging product for retention of vitamin C content (5.837 mg/100g) antioxidant activity (7.458%) and phenolic compounds (2526.603mg/100g) after 30 days of storage. Figures for plastic boxes were 5.641 mg/100g, 5.249% and 2361.657 mg/100g, respectively. Similarly, zipper bags were 5.32 mg/100g, 5.895 % and 2173.867 mg/100g respectively. Sensory evaluation in terms of taste, color, texture, and overall acceptability showed that polypropylene packaging gave favorable scores and the products were highly accepted by trained evaluators.

The possibility of the application of the fourier transform near-infrared reflectance spectroscopy (NIRS) to the analysis of the selected quality parameters in the mustard oil was followed to determine oil, protein, erucic acid and crude fibre content at the Central Soil Salinity Research Institute, Karnal, India. The samples were analysed by reference methods and by the fourier transformed near infrared (FT-NIR) spectroscope at integrating sphere within reflectance mode in the wavelength range 10 000&ndash;4000/cm (1000&ndash;2500 nm) with 32 scans. To develop the calibration model for the examined components, the partial least square was used and this model was validated by full cross validation. The coefficients of determination (r<sup>2</sup>) for intact seeds were 0.907, 0.922, 0.902 and 0.903 for oil, protein, erucic acid and crude fibre content, respectively thus showing that NIRS calibrations are applicable for the estimation of seed quality parameters which is highly desirable in Brassica breeding programs for a quick and non-destructive analysis of oil, protein, erucic acid and crude fibre contents in intact seed.

The aim of the study was to analyse foliar feeding of winter wheat cv. ‘Kobra’ in combination with different soil fertilization treatments with calcium and magnesium compounds. The foliar fertilizers INSOL PK + 5% urea solution and EKOSOL U were applied 3 times during the during the growing season in four soil fertilization treatments: control without fertilization, NPK, NPK + MgSO<sub>4</sub> × 7H<sub>2</sub>O, and NPK + CaO + MgO. The investigations involved a 3-year field experiment established on medium soil with a pH of 4.2 in 1 mole KCl × dm<sup>-3</sup> and with the granulometric composition of clayey silt. The soil was characterised by a low content of available phosphorus and potassium as well as a very low content of sulphur and magnesium. The foliar fertilizers applied and the soil fertilization treatments had a varied effect on the yield parameters, the macronutrient content in grain and straw, and the content and quality of gluten. Among the soil fertilization treatments, the best production results and quality parameters of winter wheat were obtained after the application of the dose with magnesium lime. The foliar fertilizers had a greater impact on yield and gluten content than on the mineral composition of winter wheat grain and straw.

Ripening stage is one of the key factors in determining quality of olive fruits and related oils. This research, thus, was aimed to study the influence of three different harvesting times on the quality parameters of olives and related oils of three autochthonous Sardinian cultivars, Sivigliana da olio, Semidana, and Corsicana da olio. We evaluated several parameters in olive fruits (dry matter, oil content, total soluble solids, total polyphenol and antioxidant activity) and oils (legal indices, total chlorophylls and tocopherols, single polyphenols and volatile compounds, antioxidant activity). The results obtained in olive fruits showed that all the parameters changed significantly during ripening and seem to confirm that the best harvesting time is that selected by the growers, that is when 70% of olives has just turned dark-colored and the rest is green. Results on oil evidenced that all the samples fulfilled the requirements of the European community for extra-virgin olive oils and showed a decrease in total chlorophylls and tocopherols, simple phenols and antioxidant activity during ripening, except for Sivigliana da olio oils, which evidenced an increase in simple polyphenols at the last sampling. A total of 17 volatile compounds were found on oils and those responsible for the green notes of the oils increased during ripening. PCA analysis well distinguished Sivigliana da olio olives from the other two cultivars and, in general, the genetic factor better explained variability, with respect to the ripening degree.
