Der internationale organische stickstoffdauerdüngungsversuch (IOSDV) novi sad nach 12 jahren

Ljubinko Starčević; Miroslav Malešević; Branko Marinković; Jovan Crnobarac

Der Internationale Organische Stickstoffdauerdungungsversuch wurde 1983/84 auf Los‐Schwarzerde in Novi Sad mit je 4 Stufen organischer Dungung und je 5 Stufen Mineral‐N‐Dungung und der Fruchtfolge Zuckerruben‐Mais (mittelspat)‐Mais (mittelfruh)‐Winterweizen angelegt. Die Ertrage der 1. bis 3. Rotation und der Zuckergehalt von Zuckerruben im Zeitraum 1984–1995 werden mitgeteilt. Der Einflus der organischen Dungung war relativ gering. Grosen Einflus auf die Ertrage hat die organische Dungung bei Zuckerruben und Gerste erzielt. Der Einflus der Mineral‐N‐Dungung war bei den Pflanzenarten ganz unterschiedlich. Der Stickstoff hat den grosten Einflus auf Winterweizen und Zuckerruben und den schwachsten auf Mais.

The objectives of this study were to determine the effects of fertilization system, nitrate (NO3)– nitrogen (N) distribution along soil profile, and their interaction on corn yield. The study was conducted at the experimental field of Institute of Field and Vegetable Crops in Novi Sad (Serbia) during 2001–2004. Corn monoculture included four fertilization variants: control (Ø), nitrogen–phosphorus–potassium (NPK) mineral fertilizers, mineral fertilizer + corn stalks (NPK + S), and mineral fertilizers + manure (NPK + M). The greatest yield was found in the variant NPK + M (9.25 t ha−1). Path coefficients showed that greatest direct positive effects on corn yield were exhibited by NO3-N levels at soil depths of 60–90 cm and 30–60 cm. The path analysis showed that winter precipitation (WP) had a direct negative effect on yield performance. However, the effect of the downward movement of NO3-N from the topsoil to deeper soil layers of WP on yield was positive.

A permanent trial with organic and mineral fertilizers in monoculture and two-crop rotation as a basis of sustainable maize production

A permanent field trial with different fertilization variants, monoculture and two-crop rotation was established in 1965 at Rimski ˇSancevi experiment field of Institute of Field and Vegetable Crops in Novi Sad, on the calcareous chernozem soil. This paper analyzes the experiment data obtained in the period 1971–2001. Yield trends were negative in all fertilization variants, due to unfavorable weather conditions during the second sub-period and the occurrence of Diabrotica virgifera in monoculture. Grain yields were higher in the two-crop rotation than in the monoculture. Highest yields and quality were achieved in both cropping systems when manure and mineral fertilized were applied in combination. The application of manure alone showed significant advantages over the sole application of NPK mineral fertilizers. Plowing under of harvest residues in combination with application of NPK mineral fertilizers is an advantageous solution when manure is not available. In addition to optimum yields and top quality, the variants with combined application of manure and mineral fertilizers left the highest amounts of NO3-N in soil after harvest. For chemozem-type soils with deep ground water table, where there is no risk of nitrate leaching, the dosing of N fertilizers should be further refined. The NO3 level after crop harvest, as a criterion of environmental protection efficiency, should be diversified to fit different soil types and different agro-ecological regions.

Zusammenfassung:Die Wirkung elektromagnetischer Resonanz-Impuls-Stimulation auf den Keimungsprozess von Weizen wurde anhand von vier Winterweizen-Sorten untersucht. Je nach verwendeter Frequenz variierte die Masse des oberirdischen Keimlinganteils von 0,0 bis 36% bei der Sorte „Jarebica“, von –7,4 bis 11,1% bei der Sorte „Pobeda“, von 7,7 bis 53,8% bei „Kremna“ und von –35 bis 15,2% bei „Evropa 90“. Die Abweichungen bei der Wurzelmasse beliefen sich von –10,8 bis 46,0% bei „Jarebica“, von –7,1 bis 64,3% bei „Pobeda“, von 22,7 bis 204,5% bei „Kremna“ und von –15,9 bis 72,8 bei „Evropa 90“.Summary:Effect of resonant impulse electromagnetic stimulation on initial plant growth has been studied in four winter wheat varieties. Depending on the frequency applied, the mass of the aboveground part of seedlings varied from 0,0 to 36% in the variety Jarebica, from –7,4 to 11,1% in Pobeda, from 7,7 to 53,8% in Kremna and from –35 to 15,2% in Evropa 90. The variations in root mass were from –10,8 to 46,0% in Jarebica, from –7,1 to 64,3% in Pobeda, from 22,7 to 204,5% in Kremna and from –15,9 to 72,8 in Evropa 90.

Zusammenfassung:Der Ernteertrag ist abhängig von einer Anzahl von Faktoren, u.a. auch biophysikalischen Einflüssen. Die Wirkung verschiedener niederfrequenter elektromagnetischer Impulse auf den Keimungsprozess von Mais wurde an der Hybridsorte NSSC-420 untersucht. Die Versuche wurden in einer Nährlösung durchgeführt. Folgende Pflanzenparameter wurden dabei überwacht: Masse und Länge der Wurzel sowie des oberirdischen Pflanzenteils, Wurzelvolumen und die gesamte und aktive Oberfläche der Wurzel. Unter den untersuchten Frequenzen schnitten die mit B und D gekennzeichneten erheblich besser ab als die Kontrolle hinsichtlich der Zunahme der Trockensubstanzmasse des oberirdischen Pflanzenteils (jeweils 60,7 und 49,2%) und der Pflanzenhöhe (7,1 und 9,1% oder 3,3 und 4,3 cm). Die Masse der Wurzelfrischsubstanz erhöhte sich um 31,2 bzw. 35,3% , die Masse der Wurzeltrockensubstanz um 38,8 und 34,7% oder 18,9 und 17,2 mg. Das Wurzelvolumen nahm um 44,4 und 31,5% zu. Die Gesamtoberfläche nahm um 0,04 bzw. 0,41 m2 zu.Summary:Crop yield depends on a number of factors including biophysical ones. Effects of different low-frequency electromagnetic pulses on the initial growth of corn have been studied in the hybrid NSSC-420. Experiments have been conducted in a nutritive medium. The following plant parameters have been monitored: mass and length of the root and the aboveground part, root volume and total and active surfaces of the root. Among the frequencies studied, those labeled B and D were significantly better than the control regarding dry matter mass increment of the aboveground part (60,7 and 49,2%, respectively) and plant height (7,1 and 9,1% or 3,3 and 4,3 cm, respectively). The mass of root fresh matter was increased by 31,2 and 35,3%, respectively, root dry matter mass by 38,8 and 34,7% or 18,9 and 17,2 mg, respectively. Root volume was increased by 44,4 and 31,5% respectively, total surface by 0,73 and 0,56 m2, respectively, and total surface by 0,04 and 0,41 m2, respectively.
