Uticaj produžnog dejstva meliorativne obrade zemljišta na razvoj korenovog sistema, morfološke i produktivne osobine ozime pšenice
The paper deals with subsequently effect of ameliorative tillage on the dynamics of some important productive morphology and productive characteristic in winter wheat. The trial was carried-out at the Maize Research Institute 'Zemun Polje' experimental fields in Krnjesevci near Belgrade on meadows chernozem soil type during 2009/10. The following ameliorative and conventional tillage systems were included in investigation: 1. Ameliorative tillage system includes new types machines for field systematization-scrapers (USM 5) in autumn, drainage plow on the depth 60-80cm, and sub-soiling with heavy vibratory sub-soiler VR 5 on 30-35cm depth. After basic tillage we prepared soil for seeding with preparation by disking and harrowing 2. Control variant without ameliorative measures. The following morphological and productive properties of winter wheat were studied: root biomass, stalk height, head, ear number, and grain yield. Ameliorative tillage systems had subsequently effects for all investigated morphology properties on this heavy soil type. Many of them are important for productive properties were statistically significant compared with control. Ameliorative tillage system increase significantly grain yield of winter wheat kg/ha compared with control.Ispitivanje uticaja sistema meliorativne obrade zemljišta zasnovanog na novim konstrukcionim rešenjima i tehnologiji (ravnanje zemljišta+podrivanje krtičnim plugom+vibraciono razrivačko oruđe) tokom 2008/09, odnosno njegovog produžnog dejstva na morfološke i produktivne osobine ozime pšenice obavljeno je na imanju Instituta za kukuruz 'Zemun Polje' u Krnješevcima u 2009/10. godini. Pratili smo uticaj produžnog dejstva meliorativnog sistema obrade zemljišta na važnije morfološke osobine ozime pšenice u dva roka, u bokorenju i u klasanju. Na kraju vegetacionog perioda pred žetvu uzeli smo uzorke za prinos zrna i druge morfološke karakteristike. Nasuprot meliorisanoj površini imali smo kontrolnu površinu. Primenjene meliorativne mere mere imale su pozitivan uticaj odnosno produžno dejstvo osetilo se i u drugoj godini posle primene što se vidi iz rezultata prinosa zrna ozime pšenice koji je veći za 620 kg/ha u poređenju sa prinosom sa kontrolne varijante
Uticaj meliorativne obrade zemljišta na razvoj korenovog sistema, zakorovljenost, morfološke i produktivne osobine suncokreta i kukuruza
The paper deals with the effects of ameliorative tillage on the dynamics of some important productive morphologic characteristic in two crops sunflower and maize. The trial was carried-out at the Maize Research Institute 'Zemun Polje' experimental fields in village Krnjesevci on meadows chernozem soil type. The following ameliorative and conventional tillage systems were included in investigations: 1. Ameliorativel tillage system - (ATS) - includes new types machines for field sistematisation-scrapers (USM 5) in autamn, drainage plow on the depth 60-80 cm, and subsoiling with heavy vibratory subsoiler VR 5. on 30-35 cm depth. After basic tillage we prepared soil for seeding with preparation by disking and harrowing 2. Conventional tillage - (CT) - in this case includes ploughing to the depth of 30- 35cm + presowing preparation by disking and harrowing The following morfological and productive properties were studied: root distribution, biomass stalk, leafs, head of sunflower, ear maize, and grain yield in two growth stages at the end vegetative and in full reproductive growth stages. Ameliorative tillage systems had better effect for all investigated morphological properties on this heavy soil type. Many of them are important for productive properties was statistically significant compared with control (CT). Ameliorative tillage system increase significantly grain yield sunflower (274 kg/ha, and maize 629 kg/ha compared with conventional tillage systems on control variants.Razvoj oruđa za meliorativnu obradu zemljišta poslednje dve decenije doživljava veliki napredak. Sa ovim oruđima izvodi se obrada na teškim zemljištima dubokog profila, često sa nepropusnim slojevima ispod orničnog. Dilema da li prevrtati masu zemljišta ili je dubinski rastresati zavisi od konkretnih osobina zemljišnog tipa. Ako je u pitanju zemljište sa nepovoljnim podorničnim slojem treba izbeći prevrtanje i dati prednost rastresanju. Ispitivanje uticaja sistema meliorativne obrade zemljišta zasnovanog na novim konstrukcionim rešenjima i tehnologiji (ravnanje zemljišta+podrivanje krtičnim plugom+vibraciono razrivačko oruđe) na floristički sastav korovske sinuzije, morfološka i produktivna svojstva suncokreta i kukuruza obavljeno je na imanju Instituta za kukuruz 'Zemun Polje' u Krnješevcima tokom 2007. i 2008. godine. Pratili smo uticaj meliorativnog sistema obrade zemljišta na važnije morfološke osobine suncokreta i kukuruza (masu korena, stabla, lista i reproduktivnih organa, glavice kod suncokreta klipa i metlice kod kukuruza) u njihovim značajnim fazama porasta, na kraju vegetativne i u punoj reproduktivnoj. Na kraju vegetacionog perioda posle žetve odnosno berbe utvrdili smo prinos zrna suncokreta i kukuruza. Nasuprot meliorisanoj površini imali smo kontrolnu površinu sa ista dva useva na kojoj je izvedena samo konvencionalna osnovna obrada raoničnim plugom, a predsetvena tanjiračom i drljačom bez meliorativne obrade. Primenjene mere imale su pozitivan uticaj na praćene morfološke i produktivne osobine useva kukuruza i suncokreta. Dobijeno je statistički vrlo signifikantno povećanje prinosa zrna suncokreta za 274 kg/ha i kukuruza za 629 kg/ha u poređenju sa kontrolom gde nisu izvedene meliorativne mere
Efekti primene sistema meliorativne obrade na zemljišta teškog mehaničkog sastava u proizvodnji ratarskih kultura
In this paper influence of two tillage systems for soils of heavy mechanical composition (conventional with bottom plough and ameliorative tillage system) is analyzed. The emphasis of research, in addition to other secondary effects, is focused on the yield and the cost of production of main field crops as relevant indicators of efficiency of plant production. Production of field crops with conventional tillage system gave satisfactory yields, characteristic for a given agro-climatic conditions (quantity and distribution of rainfall, soils of heavy mechanical composition). Ameliorative tillage system of soils of heavy mechanical composition in comparison to conventional system achieved significantly higher yields of crops in dry years (8.6% sunflower, 9.9% corn), and even more in years with a lot of rainfall (21% wheat ). The research is necessary to continue in order to see the effects of ameliorative tillage system on other breeding plants, and also for observing the effects of continuous usage of this tillage system (in second, third and fourth year of production).U radu je analiziran uticaj dva sistema obrade zemljišta teškog mehaničkog sastava: konvencionalni izveden pomoću raonog pluga i sistem meliorativne obrade. Akcenat istraživanja je, pored ostalih pratećih efekata, usmeren na prinos i troškove proizvodnje glavnih ratarskih kultura kao relevantnih pokazatelja efikasnosti biljne proizvodnje. Proizvodnja ratarskih kultura izvedena konvencionalnim sistemom obrade dala je zadovoljavajuće prinose, karakteristične za date agroklimatske uslove (količine i raspored padavina, zemljište teškog mehaničkog sastava). Meliorativnim sistemom obrade zemljišta teškog mehaničkog sastava u odnosu na konvencionalni sistem postižu se značajno veći prinosi ratarskih kultura u sušnim godinama (8,6% suncokret, 9,9% kukuruz), a još više u godinama sa izraženim periodima prevlaživanja zemljišta (21% pšenica). Ova istraživanja je potrebno nastaviti zbog sagledavanja efekata primene sistema meliorativne obrade zemljišta i na druge gajene kulture, kao i radi sagledavanja efekata produženog dejstva primene ovog sistema obrade (u narednim proizvodnim godinama)
