Boron application in red clover (Trifolium pratense L.) seed production
peer-reviewedThis work is part of the research project TR-31016, funded by the Ministry of Science and Technological Development, Republic of Serbia.A field trial with four red clover cultivars was established on acid soil in order to evaluate the effect of foliar boron application on seed yield. The crop received foliar boron treatment during the second growth of the second year at two applications. Although seed yield showed a significant increase in boron-treated plants in 2011 compared with control (26.0%), its relative increase was far higher in 2010 (43.2%), which had increased total rainfall amounts during flowering. Sufficient level of boron supply to red clover plants for seed production has a remarkably positive effect under conditions hampering pollination and fertilisation.Ministry of Science and Technological Development, Republic of Serbi
Proizvodne osobine i kvalitet ploda novointrodukovanih sorti jagode
The paper presents results of the research into productive qualities and
fruit quality of the āClery, āJolyā and āDelyā strawberry cultivars, conducted during 2012
and 2013. The fruit mass and yield per crown were significantly higher in the āJolyā
cultivar. A significantly higher number of fruits per crown and higher yield per crown
were recorded in the second year of harvest, whereas the fruit mass was significantly
higher in the first year. The highest values of fruit quality parameters (RSM and total
acidity) were recorded in the āJolyā cultivar, whereas the highest values of the total
sugars, pH and the RSM/total acidity ratio were recorded in the āDelyā cultivar. A better
chemical composition of the fruit of the examined cultivars was determined in 2012. In
the overall result, the āJolyā cultivar demonstrated the best productive qualities, whereas
the āDelyā cultivar was superior from the aspect of the fruit quality.U radu su prikazani rezultati dvogodiÅ”njih prouÄavanja (2012ā2013.)

Uticaj kalcizacije na proizvodnju krme crvene deteline i italijanskog ljulja gajenih u smeŔi
This paper examines the influence of liming (control - without CaO; 3t ha-1 CaO)
on acidic soil pH of 4.8 to forage, hay yield, the share of red clover, Italian ryegrass and
weeds in the total hay yield of mixture crop. The experiment was a set up by
randomized complete block design with three replications, with the size of the
experimental plots of 5m2 (5x1m). Sowing was done on 20 cm interrow. Soil liming
was resulted in a significant increase of yields forage and hay of crops only the first cut
in 2012. In all growth during 2011 and 2012, liming is influenced significantly increase
the share of Italian ryegrass at the expense of reduction of red clover share, while the
share of weeds was not significantly changed. In the third year of production, there was
only one growth of red clover, which was very sparse and exhausted, and Italian
ryegrass was not. In such conditions, liming is influenced significantly increase the
share of red clover at the expense of a significant reduction in the share of weeds.U radu je ispitivan uticaj primene kalcizacije (kontrola ā bez CaO; 3t ha-1
CaO) na kiselom zemljiŔtu pH 4,8 na prinos krme, prinos sena, udeo crvene deteline,
italijanskog ljulja i korova u ukupnom prinosu sena zdrzuženog useva. Ogled je
postavljen po potpuno sluÄajnom blok sistemu u tri ponavljanja, sa veliÄinom
eksperimentalne parcele od 5m2 (5x1m). Setva je obavljena na meÄurednom rastojanju od
20cm. Primena kalcizacije znaÄajno je uticala na poveÄanje prinosa krme i prinosa sena
združenog useva jedino u prvom porastu 2012. godine. U svim porastima tokom 2011. i
2012. godine, kalcizacija je uticala na znaÄajno poveÄanje udela italijanskog ljulja na
raÄun smanjenja udela crvene deteline, dok se udeo korova nije znaÄajno menjao. U
treÄoj godini proizvodnje, postojao je samo jedan porast crvene deteline, koji je bio jako
proreÄen i iscrpljen, a italijanskog ljulja nije bilo. U takvim uslovima kalcizacija je
uticala na znaÄajno poveÄanje udela crvene deteline na raÄun znaÄajnog smanjenja udela

Uticaj kalcizacije zemljiŔta na prinos krme i semena Žutog zvezdana (Lotus corniculatus L.)
A prerequisite for improving birdsfoot trefoil cultivation is the production of
sufficient quantities of quality seeds. The field experiment was set 2012th in ÄaÄak on
alluvium soil type, acid reaction (pHH2O 4.8). Varieties birdsfoot trefoil (K-37 and
Rocco) were sown at a interrow spacing of 20 cm and 10 kg ha-1 seed. The aim of the
experiment was to analyze the impact of the application of limestone soil (without CaO
and treatment with 3 t ha-1 CaO) on forage yield, seed yield and yield components of
birdsfoot trefoil. The results indicate that birdsfoot trefoil was largely tolerant on
acidity. The positive influence of liming on number of stems m-2 and number of seeds
per pod in the variety Rocco contributed to its greater seed yield in relation to the
variety of K-37.Preduslov za unapreÄenje gajenja žutog zvezdana je proizvodnja dovoljne
koliÄine kvalitetnog semena. Poljski ekseriment je postavljen 2012. godine u ÄaÄku na
zemljiŔtu tipa aluvijum, kisele reakcije (pHH2O 4,8). Sorte žutog zvezdana (K-37 i Rocco)
posejane su na rastojanju 20 cm meÄuredno sa 10 kg ha-1 semena. Cilj ogleda bio je da se
analizira uticaj kalcizacije zemljiŔta (kontrola - bez CaO i tretman sa 3 t ha-1 CaO) na
kiselom zemljiŔtu na prinos krme, prinos i komponente prinosa semena sorti žutog
zvezdana. Dobijeni rezultati ukazuju da je žuti zvezdan u velikoj meri tolerantan na uslove
kiselog zemljiÅ”ta. Kalcizacija zemljiÅ”ta je ispoljila jaÄi uticaj na broj izdanaka m-2 i broj
zrna po mahuni kod sorte Rocco, Å”to se odrazilo i na njen znaÄajno veÄi prinos semena u
odnosu na sortu K-37
Influence of fertigation on generative potential and pomological properties of different apple cultivars
The paper presents an investigation into the influence of fertigation on generative potential parameters and pomological properties of apple fruits. The study was done in apple orchard of Fruit Research Institute Cacak (Serbia) over two-year period (2009ā2011) on three cultivars (\u27Morens Jonagored\u27, \u27Gloster\u27 and \u27Granny Smith\u27). Fertigation included fertilizers NPK 16:8:32, NPK 12:0:43 and PGPR ā inoculum of diazotrophic bacterium Klebsiella. Results of the study suggest that fertigation with 12:0:43 NPK fertilizer had the most pronounced effect on all generative potential parameters, except abundance of flowering (initial fruit set ā 3.71; final fruit set ā 3.31). Similarly, this fertilizer had the same effect on all yield parameters in the apple cultivars studied, i.e. yield per tree ā 9.60 kg/tree, yield per unit land area ā 24.40 t/ha, cumulative yield ā 19.20 kg/tree, cumulative yield 48.00 t/ha and yield efficiency ā 0.77 kg/cm2. Mineral fertilizer NPK 16:8:32 gave the highest abundance of flowering (4.51). In terms of pomological properties the applied fertilizers had a significant effect on fruit weight (239.05 g), soluble solids content (14.78%) and ripeness degree (4.75)
Uticaj biohemijskog sastava ploda na senzoriÄku ocenu kvaliteta ploda novointrodukovanih sorti jagode
The paper presents the results of the study conducted into the impact made by biochemical composition on sensory appraisal of the fruits of the Ź»Cleryā, Ź»Jolyā and Ź»Delyā strawberry cultivars in the period 2012ā2013. In 2012 a significantly higher content of total sugars was recorded in Ź»Delyā and Ź»Cleryā cultivars, compared to Ź»Jolyā cultivar. In 2013, a significantly higher content of total and reduced sugars were determined in the Ź»Jolyā and Ź»Delyā cultivar compared to āCleryā. Within the scope of the two years of research, the highest contents of sucrose was recorded in the āJolyā strawberry cultivar. In the first trial year, the highest content of total acids was recorded in the āCleryā cultivar, whereas in the second trial year the highest total acids content was found in the āJolyā cultivar. A high cumulative grade for the sensory quality of fruit was attained by the āJolyā cultivar, whereas the lowest cumulative grade was given to the Ź»Cleryā cultivar in both trial years. Considering the best score for the biochemical composition and sensory quality of the fruit, the āJolyā cultivar can be recommended for more intensive use in the production practice.U radu su prikazani rezultati prouÄavanja uticaja biohemijskog sastava ploda na senzoriÄku ocenu kvaliteta ploda jagode sorti Ź»Cleryā, Ź»Jolyā i Ź»Delyā u periodu 2012ā2013. godina. ZnaÄajno viÅ”i sadržaj ukupnih Å”eÄera registrovan je kod sorti Ź»Delyā i Ź»Cleryā u poreÄenju sa sortom Ź»Jolyā, u 2012. godini. U 2013. godini, znaÄajno viÅ”i sadržaj ukupnih i invertnih Å”eÄera evidentiran je kod sorti Ź»Jolyā i Ź»Delyā u odnosu na sortu āCleryā. U dvogodiÅ”njem periodu istraživanja, najveÄa vrednost sadržaja saharoze evidentirana je u plodu jagode sorte Ź»Jolyā. U prvoj godini istraživanja, najviÅ”i sadržaj ukupnih kiselina zabeležen je kod sorte Ź»Cleryā, a u drugoj godini istraživanja kod sorte Ź»Jolyā. Visoke zbirne ocene za senzoriÄki kvalitet ploda ostvarila je sorta Ź»Jolyā, a najniže zbirne ocene sorta Ź»Cleryā, u obe godine istraživanja. Najbolje rezultate u pogledu biohemijskog sastava i senzoriÄkog kvaliteta ploda ostvarila je sorta Ź»Jolyā, pa se ova sorta može preporuÄiti za intenzivnije Å”irenje u proizvodnoj praksi
Uticaj folijarne primene teÄnog organskog Äubriva na prinos i komponente prinosa semena crvene deteline na kiselom zemljiÅ”tu
The field experiment with varieties of red clover K-39 and Amos, was set up on alluvial soil type using a randomized block design with three replications and plot size 5x1m. The aim was to analyze the effect of foliar application of liquid organic fertilizer (Bioplant flora, Plant DOO, Russia) on seed yield and yield components of red clover in the conditions of dense planting. Regardless of foliar application of liquid fertilizer, cultivar K-39 had a significantly higher number of inflorescences per stem, number of inflorescences m-2, seed number per inflorescence, fertility of flowers and seed yield. Foliar application of liquid fertilizer resulted in a significant increase in the value of yield components, especially fertility and the number of flowers per inflorescence in cultivar K-39.Poljski ogled sa sortama crvene deteline K-39 i Amos, postavljen je na zemljiÅ”tu tipa aluvijum po potpuno sluÄajnom blok sistemu u tri ponavljanja i veliÄinom elementarne parcele 5x1m. Cilj rada bio je da se analizira uticaj folijarne primene teÄniog organskog Äubriva (Bioplant flora, Plant DOO, Rusija) na komponente prinosa i prinos semena crvene deteline u uslovima guste setve. Nezavisno od folijarne primene teÄnog organskog Äubriva, sorta K-39 je imala znaÄajno veÄi broj cvasti po izdanku, broj cvasti m-2, broj zrna po cvasti, znaÄajno veÄu fertilnost cvetova i prinos semena u odnosu na sortu Amos. Folijarna primena teÄnog organskog Äubriva uticala je na znaÄajno poveÄanje vrednosti komponenti prinosa, a pre svega fertilnosti cvetova i broja zrna po cvasti kod sorte K-39

The paper presents results of the research of vegetative and generative potential, phenological properties and fruit quality of the promising strawberry cultivar āLeatitiaā in the 2016ā2017 period. Significantly higher values of all tested parameters of vegetative, generative potential, productivity and fruit mass were determined in the second experimental year. High firmness values were determined in both years of the research, while significantly higher phenolics content and antioxidative capacity were registered in the fruits the second year after planting. Spread of the strawberry cultivar āLeatitiaā in production practices can be recommended primarily because of the late ripening, high productivity and very high quality of fruits.U radu su prikazani rezultati ispitivanja vegetativnog, generativnog potencijala, fenoloÅ”kih osobina i kvaliteta ploda perspektivne sorte jagode āLeatitiaā u periodu 2016ā2017. godine. U drugoj eksprimentalnoj godini, utvrÄene su znaÄajno viÅ”e vrednosti svih ispitivanih parametara vegetativnog, generativnog potencijala, produktivnosti i mase ploda. Visoke vrednosti Ävrstine ploda utvrÄene su u obe godine istraživanja, dok su znaÄajno veÄi fenolni sadržaj i antioksidativni kapacitet registrovani u plodovima jagode u drugoj godini nakon sadnje. Å irenje sorte jagode āLeatitiaā u proizvodnjoj praksi može se preporuÄiti prevashodno zbog kasnog vremena zrenja, visoke rodnosti i veoma kvalitetnog ploda
Patients\u27 Perceptions and Patient-Reported Outcomes in Progressive-Fibrosing Interstitial Lung Diseases
The effects of interstitial lung disease (ILD) create a significant burden on patients, unsettling almost every domain of their lives, disrupting their physical and emotional well-being and impairing their quality of life (QoL). Because many ILDs are incurable, and there are limited reliably-effective, life-prolonging treatment options available, the focus of many therapeutic interventions has been on improving or maintaining how patients with ILD feel and function, and by extension, their QoL. Such patient-centred outcomes are best assessed by patients themselves through tools that capture their perceptions, which inherently incorporate their values and judgements. These patient-reported outcome measures (PROs) can be used to assess an array of constructs affected by a disease or the interventions implemented to treat it. Here, we review the impact of ILD that may present with a progressive-fibrosing phenotype on patients\u27 lives and examine how PROs have been used to measure that impact and the effectiveness of therapeutic interventions
