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 ‘Clery, ‘Joly’ and ‘Dely’ strawberry cultivars, conducted during 2012 and 2013. The fruit mass and yield per crown were significantly higher in the ‘Joly’ 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 ‘Joly’ cultivar, whereas the highest values of the total sugars, pH and the RSM/total acidity ratio were recorded in the ‘Dely’ cultivar. A better chemical composition of the fruit of the examined cultivars was determined in 2012. In the overall result, the ‘Joly’ cultivar demonstrated the best productive qualities, whereas the ‘Dely’ cultivar was superior from the aspect of the fruit quality.U radu su prikazani rezultati dvogodišnjih proučavanja (2012−2013.) proizvodnih osobina i kvaliteta ploda jagode sorti ‘Clery’, ‘Joly’ i ‘Dely’. Vrednosti mase ploda i prinosa po bokoru bile su značajno veće kod sorte ‘Joly’. Značajno veći broj plodova po bokoru i prinos po bokoru zabeležen je u drugoj godini plodonošenja, dok je masa ploda bila značajno veća u prvoj godini. Najveće vrednosti parametara kvaliteta ploda (rastvorljiva suva materija i ukupna kiselost), zabeležene su kod sorte ‘Joly’, dok su najveće vrednosti sadržaja ukupnih šećera, pH i odnosa RSM/UK zabeležene kod sorte ‘Dely’. Hemisjki sastav ploda, svih proučavanih sorti, bio je izraženiji u 2012. godini. Ukupno posmatrano, najbolja proizvodna svojstva ispoljila je sorta ‘Joly’, dok je sa stanovišta kvaliteta ploda, superiornost pokazala sorta ‘Dely’

Uticaj kalcizacije zemljišta 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 Čačak 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 unapređenje gajenja žutog zvezdana je proizvodnja dovoljne količine kvalitetnog semena. Poljski ekseriment je postavljen 2012. godine u Čačku na zemljištu tipa aluvijum, kisele reakcije (pHH2O 4,8). Sorte žutog zvezdana (K-37 i Rocco) posejane su na rastojanju 20 cm međuredno sa 10 kg ha-1 semena. Cilj ogleda bio je da se analizira uticaj kalcizacije zemljišta (kontrola - bez CaO i tretman sa 3 t ha-1 CaO) na kiselom zemljištu 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 zemljišta. Kalcizacija zemljišta je ispoljila jači uticaj na broj izdanaka m-2 i broj zrna po mahuni kod sorte Rocco, što se odrazilo i na njen značajno veći prinos semena u odnosu na sortu K-37

Uticaj kalcizacije na proizvodnju krme crvene deteline i italijanskog ljulja gajenih u smeši

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 – bez CaO; 3t ha-1 CaO) na kiselom zemljištu 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 slučajnom blok sistemu u tri ponavljanja, sa veličinom eksperimentalne parcele od 5m2 (5x1m). Setva je obavljena na međurednom rastojanju od 20cm. Primena kalcizacije značajno je uticala na povećanje 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 značajno povećanje udela italijanskog ljulja na račun smanjenja udela crvene deteline, dok se udeo korova nije značajno menjao. U trećoj godini proizvodnje, postojao je samo jedan porast crvene deteline, koji je bio jako proređen i iscrpljen, a italijanskog ljulja nije bilo. U takvim uslovima kalcizacija je uticala na značajno povećanje udela crvene deteline na račun značajnog smanjenja udela korova

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 (2009–2011) 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 – 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 – 3.71; final fruit set – 3.31). Similarly, this fertilizer had the same effect on all yield parameters in the apple cultivars studied, i.e. yield per tree – 9.60 kg/tree, yield per unit land area – 24.40 t/ha, cumulative yield – 19.20 kg/tree, cumulative yield 48.00 t/ha and yield efficiency – 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 senzoričku 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 ʻClery’, ʻJoly’ and ʻDely’ strawberry cultivars in the period 2012–2013. In 2012 a significantly higher content of total sugars was recorded in ʻDely’ and ʻClery’ cultivars, compared to ʻJoly’ cultivar. In 2013, a significantly higher content of total and reduced sugars were determined in the ʻJoly’ and ʻDely’ cultivar compared to ‘Clery’. Within the scope of the two years of research, the highest contents of sucrose was recorded in the ‘Joly’ strawberry cultivar. In the first trial year, the highest content of total acids was recorded in the ‘Clery’ cultivar, whereas in the second trial year the highest total acids content was found in the ‘Joly’ cultivar. A high cumulative grade for the sensory quality of fruit was attained by the ‘Joly’ cultivar, whereas the lowest cumulative grade was given to the ʻClery’ cultivar in both trial years. Considering the best score for the biochemical composition and sensory quality of the fruit, the ‘Joly’ cultivar can be recommended for more intensive use in the production practice.U radu su prikazani rezultati proučavanja uticaja biohemijskog sastava ploda na senzoričku ocenu kvaliteta ploda jagode sorti ʻClery’, ʻJoly’ i ʻDely’ u periodu 2012–2013. godina. Značajno viši sadržaj ukupnih šećera registrovan je kod sorti ʻDely’ i ʻClery’ u poređenju sa sortom ʻJoly’, u 2012. godini. U 2013. godini, značajno viši sadržaj ukupnih i invertnih šećera evidentiran je kod sorti ʻJoly’ i ʻDely’ u odnosu na sortu ‘Clery’.

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
