The aim of this paper is to present the characteristics of new vari­eties of the onion (Zenički and Konjički), created in the Federal Institute for Agriculture Sarajevo and their suitability for cultivation in Bosnia and Herzegovina. The tests were carried out in two years (2012 and 2013) at the site Butmir (Sarajevo). The experiments were conducted in a ran­domized block system in five repetitions. The examination included the following productive traits of the onion: yield and length of the growing season. Within the qualitative characteristics, the contents of dry matters, sugars and proteins were determined in the bulb. The variety Stuttgarter was used as a standard. The new varieties are distinguished by the length of the growing period of 114-115 days. The variety Zenički has achieved a higher yield of bulbs for 17%, while Konjički for 31%, comparing to Stuttgarter. The yields of bulbs in 2013 were higher by 15% comparing to 2012. These varieties are characterized by high quality, because the dry matter content is from 13.8 to 15.88%, total sugars from 8.20 to 10.98%, and proteins from 1.50 to 1.70%, with slightly spicy taste and well wra­pped bulb.

SummaryThe effects of the time of sowing on growth and chemical composition of carrots grown from May to November were studied during 3 years.Delaying sowing for 1 or 2 months after the beginning of May resulted in a reduction in the growth of both roots and foliage and gave roots with lower dry-matter content and glucose/fructose ratio but higher amounts of hexoses, total nitrogen and amino nitrogen in root dry matter. Sowing date had no influence on the concentration of sucrose, phosphorus, potassium, calcium and magnesium in root dry matter up to 137 days from sowing. Carotene decreased only after the last sowing. Sucrose concentration of the roots increased throughout the periods studied irrespective of the time of sowing. The longer the growing period the higher was the sucrose concentration. The concentration of hexoses decreased from the first harvest at 70 days to reach a constant level at about 130 days from sowing.The results did not indicate the presence of a well-defined stage of biochemical maturity in the autumn when carrot roots are expected as most suitable for harvest and subsequent long-term storage.

Background. Representatives of the genus Allium L. are valuable food and medicinal plants that have long been used for nutrition and human health. Modern research has proved their high biological activity. Earlier, we investigated the aboveground organs of a number of wild onion species in the consumer ripeness phase. Higher content of secondary metabolites has been observed in the hemiephemeroid species A. aflatunense B. Fedtsch., A. microdictyon Prokh., and A. rosenbachianum Regel. The aim of this work was to determine the content of bioactive compounds in the green biomass of Allium species during flowering.Materials and methods. We studied the freshly harvested raw materials – leaves and flower scapes. Dry matter content was measured by drying 1 g of raw material at 100–105°C to constant weight. The amounts of phenolic compounds, pectic substances, total sugars and carotenoids were assessed spectrophotometrically using the SF-56 (Russia) and SF Agilent 8453 (USA) instruments, and ascorbic acid was measured by the titrimetric method. The result was taken as an average of three measurements for each indicator calculated on absolute dry weight of raw material (except ascorbic acid).Results and conclusions. The green biomass of Allium species was found to contain 8,2–16,2% of dry matter; 4,5–12,0% of phenolics (catechins, flavonols and tannins); 6,9–32,4% of total sugars; 9,5–12,6% of pectic compounds (pectins and protopectins); 20,8–102,5 mg% of carotenoids, and 38,0–197,7 mg% of ascorbic acid (wet weight). A significant range of variation in the content of secondary metabolites was due to the species’ characteristics and weather conditions of the growing season. A. microdictyon had a higher content of dry matter, flavonols and tannins, whereas A. aflatunense and A. rosenbachianum were rich in ascorbic acid and sugars. The findings testify to the prospects of using Allium spp. as a source of bioactive compounds.

The effects various rates of nitrogen application on accumulation of dry matter and nitrogen in potato (Solanum tuberosum L.) were studied during a short growing period of 140–180 days, at MTT Agrifood Research Finland in 2000–2001. The treatments were 0, 60 and 120 kg N ha-1 and the potato cultivars tested were Van Gogh and Nicola. Four successive harvests were made during the course of the experiment to monitor changes in the accumulation of dry matter and nitrogen over the season. Applications of nitrogen substantially increased haulm dry matter accumulation and to an even greater extent their nitrogen contents. The highest dry matter values were generally registered at 120 kg N ha-1. Dry matter and nitrogen content of haulms started to decline during the later part of season and most nitrogen was relocated to tubers. The results suggest that an application of only 60 kg N ha-1 was sufficient to promote rapid canopy development and there were only small reductions in dry matter and nitrogen accumulation until late in the season when the canopy started to senesce as nitrogen supply diminished. Tuber yield, plant dry matter and nitrogen accumulation at maturity were related to crop nitrogen supply. Although application of the high rate, 120 N kg ha-1, resulted in a significant increase in dry matter accumulation, this was not reflected in the profit because the higher nitrogen application reduced dry matter content of tubers by 2.6% in 2000 and by 1.1% in 2001 relative to the use of 60 kg N ha-1. Apparent fertilizer nitrogen recovery values on a whole plant basis ranged from 53 to 75%. The proportion of fertilizer recovered in tubers clearly declined with increase in nitrogen supply.;

Agaricus Campestris

Agaricus spp. mushrooms are edible fungi of commercial and medicinal importance. Mushrooms convert nutritionally valueless substances into proteinous food with a very efficient bioconversion. Consumption of mushrooms, has increased substantially due to their delicacy, flavour, nutritional and medicinal value, being considered an excellent source of protein, which can contribute to the formulation of a balanced diet. Three species of Agaricus spp. mushrooms were used in this study: Agaricus campestris (L. ex Fr.), Agaricus bisporus (J.E. Lange) and Agaricus blazei (Murrill). This study aims to examine the effects of blanching, soaking and manufacturing processes (sun drying, oven drying and canning) on some chemical constituents of mushrooms (soluble dry matter, protein and total sugars). The analyses were performed initially at conservation and they were repeated after 6, 12 and 18 months of preservation. Since all treatments caused reduction of the dry matter content, it can be concluded that the smallest decrease during the storage period was recorded by soaked and sun dried A. blazei (1.6 g 100 g-1 FM). The maximum soluble dry matter loss was recorded at blanched and canned A. bisporus (2.8 g 100 g-1 FM). Blanching treatment of preheated (sun dried and oven dried) samples, after storage period, led the protein content to slightly decrease, between 0.4 g 100 g-1 DM and 0.8 g 100 g-1 DM. The smallest decrease of total sugars during the storage period was registered by canned, untreated A. campestris with 1.2 g 100 g-1 DM and the largest decrease was registered by blanched oven dried A. blazei with 2.9 g 100 g-1 DM.

A pot and a field experiment were conducted to evaluate the effects of different nitrogen and chloride fertilizer levels on the nitrate content of beetroot. The yield and dry matter content were also determined. Sulphate fertilization was used as a control to chloride fertilization. There was a considerable decrease in the nitrate content of beetroots during the growing season. High nitrogen fertilization caused nitrate accumulation in both experiments. Chloride had a significant decreasing effect on the nitrate accumulation towards the middle of the growing period in the pot experiment. In the field experiment, chloride also decreased nitrate accumulation towards the middle of the growing period, soon after additional application of ammonium nitrate limestone (13.8 % NH4-N; 13.7 % NO3-N). Chloride tends to decrease nitrate accumulation only at an early stage of root development when nitrate is not the only source of nitrogen in the soil. The yield was higher on high nitrogen supply, in the pot experiment also on chloride application. Nitrogen decreased the dry matter content, but chloride had this effect only in the field experiment.

AbstractOptimal feeding of field-grown plants is thought to be a key factor modifying their growth and development. Natural biostimulants, foliar fertilizers and plant growth regulators have been applied in horticultural production; however, their effect varies depending on the plant species treated, and those have been mainly cucumber, tomato, pepper, potato, and melon. The aim of the study was to evaluate the effect of preparations produced through nanotechnology on the yield and fruit quality of sweet pepper grown under cover. The experiment comprised plants grown in three different combinations: combination I (plants treated with 2 kg ha−1Nano Active); combination II (plants treated with 1% Nano Active Forte + 4 kg ha−1Nano Active Forte + 2 kg ha−1Nano Active, a single treatment carried out at the initial stage of fruit formation); and combination III (the control, where all plants were sprayed with water).The obtained results showed that Nano Active Forte foliar treatment of sweet pepper plants significantly increased fruit yield in protected cultivation. Supplementation with foliar fertilizers modified the fruit chemical composition. Application of the Nano Active Forte preparation led to an increase in dry matter content as well as in the concentrations of total sugars, vitamin C and carotenoids. Applications of Nano Active Forte and Nano Active enhanced the potassium and phosphorus contents, while the concentrations of nitrates and calcium remained at the same level regardless of the preparations used.

Experimental cabbage hybrids, especially selected for increased dry matter content, were examined for their abilities to increase the yields of finished product (sauerkraut) and concomitantly decrease the volumes of extraneous brine. The new hybrids, containing 20% more dry matter than the commercial control (Roundup), reduced the amount of final brine 57% or 388 lbs per ton of shredded cabbage. When fermented and packaged under commercial processing conditions, Roundup produced 1928 lbs, whereas the new varieties provided 2728 lbs of sauerkraut per ton of shredded cabbage. High-solids cabbage containing greater amounts of dry matter increased the product yield 41% or 800 lbs per ton of shredded cabbage.

A two-year experiment (2009-2010) included four potato varieties (Desire, Romano, Bistra and Kis Sora). Experiments were conducted in Butmir (about 500 m/ asl) and Glamoč (approximately 900 m/ asl) region. The aim was to select new varieties for our area of cultivation. Productive characteristics of potato varieties (yield, weight and number of tubers per box) were examined. In the frame of qualitative properties, dry matter content and starch were examined. Trials were performed by randomised block design with four replications, and the results were analysed using the analysis of variance. Higher average yield was achieved by Romano cultivar by 8% compared to Desire and Kis Sora. Dry matter content ranged from 21.80% in Romano to 22.20% in Desiree. Examining varieties should be continued in the upcoming period in order to determine the most favourable conditions for cultivation in the area of Bosnia and Herzegovina.

Investigation of impact of novel plant origin products on sweet basil has been carried out in 2014–2015. The plants were grown in the poly tunnel. The test on sweet basil quality parameters was carried out in the Laboratory of the Quality of Plant Raw Materials at Aleksandras Stulginskis University applying standardized analysis methods. It has been determined that, the sweet basil comparing with the control grew best in both 2014 (80.1 cm) and 2015 (80.8 cm) when biological products Canelys, Ekoflavon and Ekoflavon + Oleorgan were applied. In 2014, the most significant absolute dry matter content (92.20%) was accumulated using Oleorgan, and in 2015, significantly the highest dry matter content (90.19%) has been accumulated using Ecoflavon + Canelys. The most significant (11.64%) crude fibre content in 2014 has been obtained under Canelys application, while in 2015, significantly the highest result (14.26%) has been collected by the control. Significantly the highest quantity of crude ash (19.44%) in 2014 has been determined when the plants were treated with Canelys, however in 2015, the best result (21.86%) has been obtained after the use of the Oleorgan. The most significant (20.07%) crude protein content in 2014 has been accumulated when the plants were treated with Ekoflavon. Therefore, in 2015 significantly the highest (16.68%) crude protein content was found in the treatment Ekoflavon + Canelys, still the result did not differ significantly from the treatment when only Ecoflavon was used. The aim of the study was to investigate the influence of some biological products on the growth and qualitative characteristics of sweet basil.

Variability refers to a process by which differences occur among individuals of the same plant species. However, some characteristics change very little while others, especially quantative ones, change rather quickly and readily even when environmental conditions change slightly. This fact has prompted an investigation aimed to establish the variability of pomological characteristics of the Sumatovka cv. apple tree, a rather old and autochthonous cultivar grown widely throughout Eastern Serbia. Its special characteristic is an ability to grow and bear fruit without any particular care and cultivation, and in conditions of especially severe water deficiency and drought. Sumatovka cv. fruits are small- or medium-sized on the average, the length Measuring 51.3 ? 6.62 mm (CV 12.9%), width 55.5 ? 6.35 mm (CV 11.4%), pedicel lenght 19.5 ? 3.2 mm (CV 16.4%) and fruit mass 66.0 ?20.6 g (CV 31.3%). Total soluble dry matter content of the mesocarp varies between 15.6 and 1.92% (CV 12.31%), total sugars 14.3 ? 4.7% (CV 32.8%) and total sour substances 0.95 ? 0.11% (CV 18.6%). Especially examined were the large-sized Sumatovka fruits measuring 72.0 mm in lenght and width, and 169.4 g in mass.
