Ekonomska analiza sorte Gala u integralnoj proizvodnji jabuke

The cultivar Gala is a very attractive apple that comes from New Zealand, and is obtained by crossing cultivars Golden Delicious and Kidd's Orange Red.On average for the period 2008-2013 in the analyzed production of apples the total cost of production amounted to 1,009,787 din/ha. Gross wagesin the amount of 392.360 din/ha occupy a share of the 38.85 % of total costs. According to the representation in the total costs then come material costs (share 23.13%). The calculated cost price is on average 20.23 din/kg, with a variation of the observed years of 14,10 din/kg in 2011 to the 34,43 din/kg in 2008 year. Assuming that the in 2013 year was achieved average sales price of first class apples from 41 din/kg, with an average cost price of 21 din/kg, achieved a profit of 1.669.600 din/ha, which is very convenient.Ispitivana sorta Gala je izuzetno atraktivna jabuka koja dolazi sa Novog Zelanda, a dobijena je ukrštanjem sorti Golden Delicious i Kidd’s Orange Red.

Uticaj tehnologije gajenja na prinos ozime pšenice

This paper deals with result of the effects of different technologies on grain yield of winter wheat in investigated period (1999/00-2001/02) on the chernozem luvic soil type. Tillage systems and fertilization with nitrogen fertilizers in applied technologies have a big influence on grain yield of winter wheat. The results of our investigation show that yield grain of winter wheat was higher 11.65% in technologies which included mulch tillage system then conventional technologies. Technology with no tillage system decreased grain yield of winter wheat. Amounts of inorganic nitrogen fertilizers as main factor have effect on the grain yield of winter wheat. Grain yield increased with the level of inorganic nitrogen.U radu je ispitivan uticaj tri tehnologije gajenja ozime pšenice (konvencionalne i dve konzervacijske) na prinos zrna ozime pšenice sorte Pobeda. Ispitivanje je obavljeno na "Radmilovcu" eksperimentalnom dobru Poljoprivrednog fakulteta u Zemunu na zemljištu tipa izluženog černozema u trogodišnjem periodu (1999/2000-2001/2002. g.). Tehnologija gajenja ozime pšenice koja uključuje konzervacijski sistem obrade zemljišta sa čizel plugom i različitim nivoima prihranjivanja azotom pokazao je niz prednosti u odnosu na tehnologiju gajenja sa konvencionalnom obradom raoničnim plugom i u odnosu na tehnologiju gajenja sa direktnom setvom. Najveći prinosi ozime pšenice dobijeni su u tehnologiji gajenja sa konzervacijskom obradom zemljišta. Prinos zrna pšenice u tehnologiji gajenja sa zaštitnom obradom zemljišta bio je značajno veći u trogodišnjem proseku za 11.65% od prinosa u konvencionalnoj tehnologiji, a vrlo značajno veći za 26.17% od konzervacijske tehnologije gajenja koja uključuje direktnu setvu. Prihranjivanje sa količinom od 60 kg/ha uticalo je na povećanje prinosa prosečno za 20,44%, a sa 120 kg/ha za 24.73%, u odnosu na kontrolu bez prihranjivanja

Organska proizvodnja alternativnih vrsta ozime pšenice

The aim of this paper is to outline the potentional interests of alternative small grains as organic crop production. This paper deals with result of the effects organic field production on grain yield of different alternative winter wheat cultivars in investigated period (2005/06-2006/07) on the chernozem luvic soil type in Radmilovac- Experimental field trial Faculty of Agriculture Belgrade-Zemun. The results of our investigation show that yield grain of winter wheat was higher in first year with better meteorological conditions. Alternative small grains (Tr. aestivum ssp compactum, Tr, durum and Tr. Spelta) gives lower grain yield compared with comercial cultivar NS-40S. This is weel known fact but alternative small grains in organic production have a better quality and price on markets. Combination with organic ferttilizer and microbiological fertilizer have better effect on the grain yield of different specious winter wheat compared with organic fertilizers. Grain yield increased with the level of inorganic nitrogen. An alternative crop make a positive contribution by increasing divesity on the farms income base, spreading out risks reducing weakness in the farm system or broadening the base operations.U radu je ispitivan uticaj organske tehnologije gajenja ozime pšenice na prinos zrna alternativnih vrsta strnih žita. Ispitivanje je obavljeno na "Radmilovcu" eksperimentalnom dobru Poljoprivrednog fakulteta u Zemunu na zemljištu tipa izluženog černozema u dvogodišnjem periodu (2005/06 i 2006/07 godina). Organska tehnologija gajenja uključivala je konvencionalnu obradu zemljišta, đubrenje organskim i mikrobiološkim đubrivom bez hemijske zaštite useva i tri sorte različitih alternativnih vrsta ozime pšenice. Najveći prinos zrna u ovom ispitivanju u organskoj tehnologiji gajenja dobijen je sa vrstom Triticum aestivum ssp. vulgare - inače hlebnom sortom NS 40S što je statistički vrlo signifikantno u poređenju sa prinosom alternativnih žita. Kod alternativnih žita dobijeni su ujednačeni, ali niži prinosi. Dobijene razlike u prinosu zrna nisu bile statistički opravdane. Međutim, dobijeni rezultati pokazuju da ove vrste pšenice, i pored nešto nižeg prinosa koji daju od konvencionalnih hlebnih sorti, zbog svojih specifičnosti u kvalitativnom smislu mogu biti vrlo interesantne proizvođačima za gajenje u organskoj proizvodnji budući da poseduju dobre parametre za specijalne namene.Većom cenom ovih proizvoda iz ekološke proizvodnje i sa manjim prinosom ova proizvodnja može biti vrlo isplativa posmatrano ekonomski

Thromboembolic Disease in Patients With Cancer and COVID-19: Risk Factors, Prevention and Practical Thromboprophylaxis Recommendations–State-of-the-Art.

Cancer and COVID-19 are both well-established risk factors predisposing to thrombosis. Both disease entities are correlated with increased incidence of venous thrombotic events through multifaceted pathogenic mechanisms involving the interaction of cancer cells or SARS-CoV2 on the one hand and the coagulation system and endothelial cells on the other hand. Thromboprophylaxis is recommended for hospitalized patients with active cancer and high-risk outpatients with cancer receiving anticancer treatment. Universal thromboprophylaxis with a high prophylactic dose of low molecular weight heparins (LMWH) or therapeutic dose in select patients, is currentlyindicated for hospitalized patients with COVID-19. Also, prophylactic anticoagulation is recommended for outpatients with COVID-19 at high risk for thrombosis or disease worsening. However, whether there is an additive risk of thrombosis when a patient with cancer is infected with SARS-CoV2 remains unclear In the current review, we summarize and critically discuss the literature regarding the epidemiology of thrombotic events in patients with cancer and concomitant COVID-19, the thrombotic risk assessment, and the recommendations on thromboprophylaxis for this subgroup of patients. Current data do not support an additive thrombotic risk for patients with cancer and COVID-19. Of note, patients with cancer have less access to intensive care unit care, a setting associated with high thrombotic risk. Based on current evidence, patients with cancer and COVID-19 should be assessed with well-established risk assessment models for medically ill patients and receive thromboprophylaxis, preferentially with LMWH, according to existing recommendations. Prospective trials on well-characterized populations do not exist

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements
