Growth, decorative and nutritional values of ornamental cabbage (Brassica oleracea L.) in flowerbed conditions

Ornamental cabbages are cultivars of cabbages grown for decorative purposes due to the varied shape and colour of their internal leaves. The aim of the study was to determine the course of growth and to assess the decorative and nutritional value of two cultivars of ornamental cabbage (‘Pigeon Red’, ‘Coral Prince’) grown in a flowerbed along with annual plants: the French marigold (Tagetes patula nana L.) and flossflower (Ageratum houstonianum Mill.), using a pine bark mulch. The impact of the marigold and flossflower on the cabbage height and foliage changed with the plant growth. Cabbages growing without the proximity to the other species had the smallest diameter and formed the least leaves; and the plant’s height was lower in September. The cabbage height, foliage and leaf colour were modified by the weather in the subsequent years of research. The proximity of the marigold or flossflower and mulching of the soil with bark did not affect the colour of the leaves. The nutritional value of the ornamental cabbage was high, and the content of the mineral components in the leaves depended largely on their colour. The coloured leaves were more abundant in nitrogen, phosphorus, potassium and magnesium, while the green leaves contained more calcium and sulfur, and slightly more dry matter.

Background: Camel milk is very suitable for human nutritional requirements, and its composition has similarities to mother’s milk. Many scientific researches focusing on the myth of nutritional and therapeutic properties of camel milk have been brought to public attention.Aim: This study aims to clarify the impact of early weaning on constituents and nutritional values of the milk of camels reared under a modern farming system during four months postpartum.Methods: Eight lactating camels and eight calves were selected immediately after calving and were assigned to two equal groups under a semi-intensive system in a farm. In the early weaning group (G1), all the calves were allowed to freely suckle their mother’s teats from birth to 30 days postpartum. Afterward, the calves were used to stimulate milk letdown for each of the camels’ teats for a few seconds before the milking procedure. While in the late weaning group (G2), the calves freely suckled their mother’s teats up to 80 days postpartum. Afterward, the calves were restrictedfrom suckling and were used mainly to stimulate milk letdown for the milking procedure. Collection of milk samples started in the 2nd week of postpartum and continued over biweekly intervals up to 16 weeks to determine major fat, protein, lactose, solid non-fat (SNF), and density percentages.Results: The results revealed significant differences in fat, lactose, and density content between groups. We reported significant increases in the percentages of fat, lactose, protein, and SNF levels, besides fluctuations in density with the advancement of the lactation stage.Conclusion: In the early weaning group, the dams produced milk containing high levels of fat and SNF compared to the lactating dams in the late weaning group.

The Impact

The aim of the study was to compare yields and nutritional value of selected species and cultivars of forage grasses under the optimal moisture conditions and long-term drought stress. The regenerative capacity of plants after dehydration was also assessed. The pot experiment was conducted in years 2009–2010 in IUNG-PIB’s greenhouse in Puławy, Poland. Nine cultivars of four species: Dactylis glomerata (‘Amera’, ‘Minora’), Festuca pratensis (‘Skra’, ‘Fantazja’), Festulolium braunii (‘Felopa’, ‘Agula’, ‘Sulino’), and Lolium multiflorum (‘Gisel’, ‘Lotos’) were investigated in well-watered conditions (70% field water capacity – FWC) and under a long-term drought stress (40% FWC).The study showed that stress caused by soil moisture deficiency significantly reduced yields of D. glomerata, F. pratensis, F. braunii, and L. multiflorum. The total yield of dry matter under stress conditions was about 31% lower, compared to the performance achieved on the optimally moisturized treatment. The smallest reduction in dry matter yield under the conditions of water deficit was recorded for D. glomerata, which makes it the most resistant to stress, followed by F. pratensis. The resistance of F. braunii and L. multiflorum to stress was similar and significantly lower. There was a various response of different grasses to the water stress. On the basis of the value of the DSI (drought susceptibility index), the tested cultivars were ranked depending on the sensitivity to drought, starting with the most resistant cultivar: ‘Minora’, ‘Skra’, ‘Fantazja’, ‘Amera’, ‘Sulino’, ‘Agula’, ‘Gisel’, ‘Lotos’, and ‘Felopa’. The digestibility of dry matter and nutrient value of the grasses depended on both the level of soil moisture and grass species. Under the water stress, the digestibility and protein value increased compared to the control objects. Lolium multiflorum and F. braunii had the best nutritional value, while D. glomerata – the weakest.

Grana Cheese

AbstractWith the aim to reduce the Na content, hard cheeses manufactured using the same technology as for Grana cheese (Grana-type) were salted using three brines containing different amounts of KCl (K-brines) and compared with control cheeses, salted with marine NaCl. A lower weight loss was observed in cheeses salted with K-brines (K-cheeses), whereas the yield and dry matter did not differ significantly between K-cheeses and controls. After 3 months of ripening (T3), the distribution of the Na cations (Na) was centripetal, with a higher Na concentration in the outer (0–3 cm of depth) layer, whereas the K cations (K) seemed to diffuse into the cheese more rapidly and homogeneously. Starting from the 6th month (T6), the distribution of both Na and K was stabilized through the different cheese layers. The use of the brine with the highest concentration of potassium (53.8% K) enabled us to successfully halve the Na content compared to the controls whereas, with the other brines, the reduction of Na was below 30%. At the end of ripening (T9), all the cheeses were without defects and the partial substitution of Na with K did not impact on the chemical composition, microbiological characteristics and ripening process. The sensory evaluation did not show any difference between K-salted and control cheeses in discriminant analysis.

The Impact

Potato cultivation is quite demanding in inorganic nutrients and adequate fertilization is a key factor for maximizing yield and producing tubers of high quality. In the present study, a field experiment was carried out to evaluate the effect of various forms of fertilization on crop performance and the nutritional value and chemical composition of two potato varieties (cv. Spunta and cv. Kennebec). For this purpose, five different fertilizer treatments were applied namely: control (C), standard fertilizer (T1), standard fertilizer + zeolite (T2), manure (T3) and slow release nitrogen fertilizer (T4). According to the results, it was observed that slow release treatment (T4) achieved the highest yield for both varieties, while the control treatment presented significantly lower yield compared to the studied fertilization regimes. The dry matter of leaves and shoots was higher in T1 treatment for cv. Kennebec and in T2 and T4 treatments for cv. Spunta, whereas the control treatment presented the highest dry matter content in tubers for cv. Kennebec and T2 and T3 treatments for cv. Spunta. A significant effect of the fertilization regime was also observed on the nutritional value of tubers and more specifically the protein, ash and fat content was increased by treatments T1 and T4, while carbohydrate content was also increased by T3 and T4 treatments for both varieties. Similarly, the total sugars, organic acids, β-carotene and lycopene content was increased in T3 treatment for the Spunta variety, while the antioxidant capacity showed a varied response depending on the fertilizer regime and the tested variety. In conclusion, the fertilization regime has a significant effect not only on the tuber yield but also on the quality of the final product and should be considered as an effective tool to increase the added value of potato crop.

The Impact

The objective of this research was to investigate the effect of seasonality on the chemical composition and concentration of phenolic compounds in some ligneous species. The research was conducted at the Aristotle University’s farm, Thessaloniki, Greece. From five ligneous species (Robinia pseudoacacia var. monophylla, Amorpha fruticosa, Colutea arborescens, Morus alba and Arbutus unedo) samples (leaves and twigs) were collected during two different seasons (spring and autumn). All samples were analyzed for crude protein (CP), Neutral Detergent Fiber (NDF), Acid Detergent Lignin (ADL) and in vitro dry matter (DM) digestibility (IVDMD), as well as for total phenols (TPH), total tannins (TT) and condensed tannins (CT). The CP content was generally lower and higher in leaves and stems of A. unedo and R. pseudoacacia, respectively compared to the other tested species. A. unedo had the highest values in NDF and ADL in leaves and the highest ADL content in stems. M. alba and C. arborescens in leaves and C. arborescens in stems had the lowest values of ADL content. M. alba had the significantly highest value in IVDMD and A. unedo the lowest one in both leaves and stems. Season had no significant effect on TPH, TT, and CT of leaves, while in stems they were significantly higher in autumn. A. unedo had the highest concentration of TPH, TT and R. pseudoacacia of CT in the leaves. TPH, TT, and CT concentration in stems was significantly higher in A. unedo. According to the findings, the impact of maturation on the type and the concentration of phenols and tannins is species-dependent.

In the years 2012–2014, at The National Institute of Horticultural Research in Skierniewice, research was carried out on determining the impact of various methods of weeding on leek yield, its storage stability and nutritional value after harvest and storage. In the field experiments the following methods were compared: mechanical treatments, mechanical treatments + growth stimulator, soil mulching with polypropylene and black foil and hand weeding. After harvest the leek were storage at the temperature 0°C for 124–150 days depending on the year and after the storage it was sorted as: marketable leeks and plants with diseases symptoms and rotten plants, and also leek’s natural weight loss was determined. After harvest and after storage, the content of dry matter, total sugars and soluble phenols in leeks was determined. The highest marketable yield immediately after harvest was obtained from plants mulched with black materials. After storage, the most marketable leeks were obtained from the control and hand weeded during cultivation. Chemical composition of leek was analysed after harvest and after the storage period. After harvest the highest yield from leek grown in black mulch were obtained and after the storage from control and hand weeding. Chemical analyses showed that the highest dry matter and total sugars contents were found in leek weeded by hand, and after storage mulched with black and polypropylene foil. After harvest, the highest content of soluble phenols was recorded in leek weeded mechanically and treated additionally with a growth stimulator, and after the storage – in mechanically weeded leeks.

Two experiments were done on the digestibility of Townsville lucerne seed with pod by sheep in metabolism cages. In one experiment, all sheep were fed the same amount (454 g dry matter seed with pod each day) and mean dry matter digestibility was 58.6 � 3.4 per cent. In the other, three different levels of seed with pod were fed, and mean organic matter digestibility ranged from 54.0 � 1.2 to 68.3 4 1.8 per cent, but digestibility was not significantly inversely related to mean organic matter intake which ranged from 438 � 69 to 335 & 10 g/day (P>0.05). The seed with pod contained, as per cent of dry matter, 5.54 per cent nitrogen, 0.36 per cent phosphorus, 0.30 per cent sulphur, and 0.88 per cent calcium. The sheep were in positive nitrogen balance, but in negative phosphorus balance. Between 8 and 14 per cent of actual seed consumed was defaecated unbroken. Up to 25 per cent of the faecal organic matter was unbroken seed, which was of high germination capacity (76 per cent). Amount of defaecated seed (P<0.001) and the defaecated seed as a percentage of faecal organic matter (P<0.02) were linearly related to amount of actual seed consumed. Factors affecting the amount of undamaged seed in the faeces and a possible technique for assessing seed consumption by grazing animals are discussed.

AbstractThe aim of this study was to determine the in vitro digestibility and in sacco disappearance of dry matter (DM) and neutral detergent fibre (NDF) in total almond hulls (TAH), pure almond hulls (PAH) or Debris. The TAH were used because there are no data on the effect of debris (non-hull material) on the nutritional value of almond hulls. Twelve samples of commercial almond hulls were used, with one subsample representing the TAH and the other subsample hand sorted to separate the hulls (PAH) from Debris. Gas production and Ankom Daisy method were used to determine in vitro digestibility, while two rumen-fistulated cows were used to measure in sacco disappearance of PAH and TAH. For in vitro digestibility, both PAH and TAH were more digestible and had greater gas production than Debris. The PAH had greater in vitro true digestibility on a DM basis and NDF digestibility at 48 and 72 h compared with TAH. Nonpareil hulls provided greater metabolizable energy (ME) concentration when compared with other almond varieties, with PAH supplying numerically more ME than TAH for both varieties. For in sacco disappearance, PAH had greater DM and NDF disappearance along with a greater rate of disappearance for NDF compared with TAH. This research demonstrated that Debris is highly indigestible; therefore, hulling, agronomic and harvesting practices should be focused on reducing Debris in commercial almond hulls to improve their nutritive value as a feedstuff for livestock.

In Poland, half of the grassland is neglected and requires renovation, which was the reason for starting this research project. The aim of this research was to study the grassland habitat of lowland central Poland that has water-deficient, slightly acidic mineral soil, in the years 2013–2016. Specifically, the impact of three methods of grassland renovation on the dry matter yield and the weight of post-harvest residues, as well as on the content of particular nutrient components in the soil, were determined. Three legume–grass mixtures were used for the renovation. The study shows that the method of renovation (ploughing, harrowing, and herbicide + direct sowing) did not have a significant effect on the dry matter yield nor on the weight of the post-harvest residues or the content in the soil of some nutrients. The highest yield was obtained from the “Original” mixture with 50% of legumes in the seed mix. After the renovation, 5.03–7.17 t·ha−1 of post-harvest residues were obtained (mainly grasses and roots of plants, 68.7–71.1%). After three years from renovation, the soil pH significantly decreased and the content of Ca and Mg increased, while the nitrogen, phosphorus, potassium, and Corg compounds remained at an unchanged level. The concentration of various forms of nitrogen, P2O5, K2O, Ca, and Corg decreased in the deeper soil layer (down to 60 cm).
