Complex evaluation of agrotechnical factors in rape seed
Published December 15, 2010

A polifactorial field trial with rape was carried out in the crop-years of 2007/2008 and 2008/2009 at the Látókép Research Centre of University of Debrecen, 15 km away from Debrecen. The soil type of the research area was a calcaric chernozem, with a levelled and homogeneous surface. Our investigations on the dynamics of lodging proved that ...rape can easily be lodged under unfavourable weather conditions, which results in a significant crop failure: In crop-year 2009 yields were 1.0-1.5 t ha-1 higher than in 2008, when the weather conditions were more unfavourable. In both crop-years the influence of sowing time on the crop yield of rape was examined in three soil cultivation systems, with ploughing, loosening or disking. Different sowing time influenced the yield of rape in both crop-years significantly. In the crop-year of 2007/2008 – due to mild winter – we got the highest yield in the first sowing time (at the end of August) with loosening (3930 kg ha-1) and disking (3727 kg ha-1), while in case of ploughing we experienced the highest yield (3770 kg ha-1) in the second sowing time. There were no significant differences between the first and second sowing time (the end of August and the beginning of September), and in the third sowing time (end of September) also a moderate crop failure (-6.7%) cold be obtained, due to the favourable weather in winter and the water supply of the crop-year 2007/2008. In 2008/2009 all the three cultivation systems showed the best yield-results in the second sowing time (ploughing: 4886 kg ha-1, loosening: 5186 kg ha-1, disking: 5090 kg ha-1), and the first sowing time hardly differed from this (-4.1%), while the late September sowing time resulted in a significant crop failure of -11.1%.

Interactive evaluation of the main agrotechnical factors in rape production
Published November 2, 2009

Our polifactorial rape research was carried out at Látókép Research Centre of Debreceni Egyetem AMTC, 15 km away from Debrecen. The aim was to study the unique effect and the interactive effect of more factors. The research factors were the following: cultivation, time of sowing and nutrient supply. Soil moisture datas proved unambiguously t...hat increasing amounts of chemical fertilizer raise the water consumption of rape, lack of water in fertilized plots were always bigger then the water deficit in control plots. The highest amount of water deficit was experienced in the case of arable plots. However, increasing amounts of chemical fertilizers raised the amount of yield proportionately. We experienced yield depression only in the case of arable plots at the highest level of chemical fertilization. In polifactorial rape research sowing of 24th August 2007 of 2007/2008 was the most optimal in point of the amount of yield. This is most-significant in the case of loosening tillage and disking tillage plots, while the plots of ploughing lag behind those two in point of average yield. We experienced the biggest differences of yield in the case of different tillage plots of sowing on 24t August 2007. Still not even the plot with the highest average reached the limit of 4 tons, which can be attributed to high rate of lodging and the harvest loss caused by this. The biggest amount of yield was experienced in the case of sowing of 24th August 2007, with the highest level of chemical fertilization at loosening tillage plot (3930 kg/ha). We can observe big differences between the tillage methods; plots of loosening show a much better average yield then plots of disking and ploughing tillage. Considering the first observed crop year we can state that alternative tillage methods do have a future in rape growing of Hungary.

The role and impact of N-Lock (N-stabilizer) to the utilization of N in the main arable crops
Published November 2, 2014

...5); font-variant-ligatures: normal; font-variant-caps: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">The nitrogen stabilizer called N-Lock can be used primarily with solid and liquid urea, UAN and other liquid nitrogen, slurry and manure. In corn it can be applied incorporated before sowing or with row-cultivator or applied with postemergent timing in tank-mix. In postemergent timing need precipitation for long effect. In oil seed rape and autumn cereals the N-Lock should be applied with liquid nitrogen in tank mix late winter or early spring (February-March). The dose rate is 2.5 l/ha. N-Lock increases the yield of maize, winter oil seed rape, winter wheat and winter barley 5-20 %. The yield increasing can be given the thousand grain weight. In case of high doses of nitrogen it can be observed higher yield. The quality parameter also improved, especially the oil content of winter oil seed rape and protein and gluten contents of winter wheat. The use of N-Lock increases the nitrogen retention of soil and reduces nitrate leaching towards the groundwater and the greenhouse effect gas emissions into the atmosphere. The degradation of the applied nitrogen is slowing down and the plant can uptake more nitrogen in long period. The effect of N-Lock the nitrogen is located in the upper soil layer of 0-30 cm and increasing the ammonium nitrogen form. The product can be mixed with herbicide products in main arable crops.

Investigation of new seed mixtures in wildlife forage ground managem
Published February 10, 2013

...5); font-variant-ligatures: normal; font-variant-caps: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">One of the most important method of habitat development is wildlife forage ground management. Many plant species can be grown on the crop fields, as mixture, too. Use of seed mixtures has not been spread on the native wildlife forage ground, however there are many advantages of them.

The aim of the research is to examine the role of the different plant species, seed mixtures in the game feeding, the savouriness of the plants of crop fields, as well as ascertain which seed mixtures are more suitable for wildlife forage ground management. On the basis of the investigation it can be find out that big amount of forage can be produced on mixed crop fields. Buckwheat, corn, rape, millet and white lupine proved to be the most beloved plants. It is suitable to make such mixed forages and use widely in the native wildlife forage ground management,

– which assures better feed conditions for the game,

– which are more attractive for the game and can draw away from other areas, so prevent, reduce game damage in forestry sector and in

agriculture that is in the forest manager’s, agricultural and game manager’s interests, too.

Results of a Fertilization Experiment Performed with Sulphur on Rape Seed Plants
Published May 4, 2004

The sulphur fertilizing experiment was introduced in the cropping year of 2001/2002, with winter rapeseed. The experiment was performed on a farm in Magyarhomorog, Hajdú-Bihar County. By selecting the location for the experiment, we had to consider the effect of the hard winter that was very unfavourable for rapeseed production, as there was s...erious frost damage on the sown area previously used for the experiment. In the arable land experiment, results of three different doses of treatment were compared in two replicates, on meadow soil. FitoHorm 32 S solution was used as a sulphur fertilizer, in doses of 3, 6 and 10 l/ha. Evaluating the results, we tried to find a correlation between the amount of fertilizer and the amount of seed-crop or the oil content of the seed. The nitrogen and sulphur contents of the samples were determined using classical methods and an Elementar VarioMax analyser. By this way, it was possible to examine not only the role of Sulphur in rapeseed production, but also to compare and evaluate results obtained by Kjeldahl and the modern, environmentally-friendly combustion method.

Results of Sulphur Fertilization Experiment with Oilseed Rape
Published September 8, 2020

The rape is definitely a sulphur-demanding crop, which yield and the quality of its oil is threaten by the emerging shortage of sulphur nowadays. We made sulphur fertilising trials on two places in the northeastern rape growing area (in Felsőzsolca and Mezőkövesd), in the season 2001/2002. We compared the result the 5 five treating set in 2 ...repeats on brown forest soil with the results of the control plots. We used FitoHorm 32 S sulphur solution as sulphur fertiliser, with the dose of 3, 6 and 10 litres per hectare, as well as the joint effects of sulphur and boron; and the effect of boron alone. On the assessment of our results we looked for relation between the sulphur fertilising, the seed production, the oil content and the protein content.

Study of plant physiological parameters in winter oilseed rape (Brassica napus var. napus f. biennis L.) production on chernozem soil
Published February 18, 2016

We made plant physiology examinations in Arkaso winter oilseed rape hybrid substance: relative chlorophyll content (SPAD) and leaf area index (LAI) measurements. The experiment was set in University of Debrecen Agricultural Sciences Center at Látóképi Experimental Station in four replications, in two different sowing times (I. sowing date on... 08/22/2014 and II. sowing date on 09/09/2014 sowing againhappened because of the incomplete germination in the second subtance 01/10/2014) Three different plant density 200, 350 and 500 thousand ha-1, under the same nutrient supply, 45 cm row spacing. The experiment was green crop of winter wheat. The relative chlorophyll content (SPAD) and leaf area index (LAI) measurements were made in seven different times. We measured the maximum value of chlorophyll content in the first sowing time at 500, and the second sowing time at 350 thousand ha-1 plant density. The measurement results proved that there was a linear relationship between the number of plants and the LAI. The maximum leaf area index values we measured in both the sowing time at 500 thousand ha-1 reached.
