Cím:Determining the main physical characteristics of fertilisers / Zoltán Balla, András Tamás, András Vántus, Zoltán Hagymássy
Dátum:2017
ISSN:2064-7816 2064-9479
Megjegyzések:Evenly distributed fertilisation is an important demand in agricultural technology. Environmentfriendlycultivation technology requires distributing different types of fertilizers more accurately and evenly. Forthis reason, it is necessary to develop fertilizer spreader machines continuously. In developing this machinery,it is essential to know the physical properties of fertilizers. This study deals with the main factors influencingfertilisation, including surface characteristic, particle (granule) shape, particle hardness, particle size range,specific particle weight. We can determine the following characteristics: particle size and particle size distribution,bulk density, moisture content, and the angle of repose. Six different fertilizer types were examined for their mostsignificant physical characteristics from the aspect of the dispersion of fertilizer particles. The measured moisturecontent, space filling and fraction characteristics affect storage and transport properties.

Cím:Effect of tillage and fertiliser treatments on yield of maize (Zea mays L.) hybridss / Bramdeo Karamchand, Rátonyi Tamás
Dátum:2020
ISSN:2064-7816 2064-9479
Megjegyzések:This research was conducted in a spilt-plot design at the University of Debrecen Látókép Research Station, site (N 47?33' E 21?27') in 2015 and repeated in 2016. There were three main plots, each 1.0 ha in size which represents the tillage treatments: moldboard plowing (MT), strip tillage (ST) and ripper tillage (RT). Maize hybrids, Loupiac (FAO 380) and Armagnac(FAO 490) were sown at 80,000 plants ha?1 with a row spacing of 76 cm in the main plots which were subdivided to accommodate three fertiliser treatments (N0 kg ha?1 (control); N80 kg ha?1; N160 kg ha?1) with four replications. The hybrids were harvested at the end of the growing cycle with a Sampo 2010 plot harvester and the grain moisture content was computed at 15% moisture to arrive at the final yield. The findings revealed RT produced the highest yield of 10.37 t ha?1, followed by MT and ST with 10.22 and 9.60 t ha?1 respectively. There was no significant difference(p>0.05) in yield between the RT and MT treatments. However, both the RT and MT were found to be statistically significant (p<0.05) when compared to ST treatment. In 2015, a relatively dry year, yield of ST plots were not significantly different compared to MT and RT plots. A positive interaction between tillage and fertilisation was evident, with higher yield variation (CV=40.07) in the non-fertilised (N0) tillage plots, compared to those which received the N80 and N160 kg ha?1 treatments (CV=22.42). Fertilizer application greatly increased the yield of maize and accounted for 43% of yield variances. The highest yield (11.88 t ha?1) was obtained with N160 kg ha?1 treatment, followed by N80 kg ha?1 ( 10.83 t ha?1), while the lowest yield (7.48 t ha?1) was recorded in the nonfertilised plots(N0 kg ha?1). Year effect was highly significant with vast variation in yield between the two years, ranging from 8.36 t ha?1 in 2015 to 12.43 t ha?1 in 2016 for the same set of agrotechnical inputs. In 2016, higher yield was obtained with increase fertiliser dosage due to favourable growing condition which allowed for better fertiliser utilisation. However, with 2015 being a relatively dry year there was no yield increasing effect with higher fertiliser dosage ( N160 kg ha?1 ). Loupiac (FAO 380) was the better performing hybrid, with a yield of 11.09 t ha?1 compared Armagnac (FAO 490) with 10.60 t ha?1 . The adaptability traits of the two hybrids appears very similar, since the yield differential between the two hybrids was almost constant (0.48 vs 0.49) in both years , despite the vast variation in weather condition.

Cím:The marigold's (Calendula officinalis L.) drug yield and economic value changes over time and composition of the essential oil active agents under different fertilization settings / Lelesz Judit Éva, Csajbók József
Dátum:2017
ISSN:2064-7816 2064-9479
Megjegyzések:While we investigated the marigold's (Calendula officinalis L.) nutrient requirements in small-plot trial we measured the raw and the dry drug yield, which we harvested in 2015 from 6th July to 17th August and in 2016 from 16 th June to 1 th August weekly. Thanks to the multiple picking the data we got, we investigated the effect of the different fertilization settings the flower drug's changes over time. The drug crop's change over time could show how many times it is economical to harvest under different fertilization settings. We monitored the harvested marigold's drug's raw and dry mass on a weekly basis. It was concluded, based on the results, in 2015 the biggest raw drug crop in the N30P40K60 fertilization setting and in 2016 in the N75P100K150 setting were measured. Both the raw and the dry mass' measurements of the case, this fertilization settings have the most important effect on the herb's yield. In the measurements of active ingredients we used SPME and GC-MS. We examined the effects of the different fertilization settings for the herb's main active ingredients of essential oil's percentage.

Cím:Effect of plant density and row spacing on maize (Zea mays L.) grain yield in different crop year / Eszter Murányi
Dátum:2015
ISSN:2064-7816 2064-9479
Megjegyzések:Nowadays the aim of crop production is to realize the highest possible yield per production area unitby the highest possible crop safety. One of the possible ways for this is to increase of plant density or to decreaserow spacing. Therefore, the plant number per unit area can be increased and the potential yield loss of individualplants is compensated by the higher plant density.The development of yield amounts of eight different genotypes was investigated in a small-plot field experimentwith four replications on a calcareous chernozem soil type at the Látókép Research Site of the University ofDebrecen in the crop years 2013 and 2014. Row distances of 45 and 76 cm, just as plant densities of 50 000, 70000 and 90 000 plants per ha were set.Significant differences were found between the yield amounts of the studied hybrids in both studied crop years,while the effect of plant density on yield amount showed different results. In the crop year of 2013 the hybridsresulted high yields in the treatment with a row distance of 45 cm and plant density of 90 000 plants per ha,however, in 2014 significant yield decrease was found in comparison with the previous year, that can be attributedto the weather conditions in the months April-May and June.Optimal plant densities of hybrids, just as the corresponding expectable yield amounts were determined withquadratic equations. Optimal plant densities of the hybrids were different in the two studied crop years: in 2013,regarding the treatments set with the row distance of 45 cm, increasing plant densities resulted in higher yields,while in 2014, the yield showed decreasing tendency parallel to the increasing plant densities, that is confirmedby the fact that plant densities of 50 000 and 65 000 plants ha-1 proved to be more favourable. Regarding thetreatments with a row distance of 76 cm, hybrids obtained their yield maximums by 80 327 plants ha-1 in 2013,while in the vegetation of 2014, by higher plant density (85 845 plants ha-1).

Cím:Plant density impact on grain yield of maize (Zea mays L.) hybrids on chernozem soil of the Eastern Hungary / Pepó Péter, Murányi Eszter
Dátum:2014
ISSN:2064-7816
Megjegyzések:The plant density response of 12 maize hybrids was tested in a favourable year (2013) under optimum agrotechnical conditions on chernozem soil by applying plant densities of 50, 70 and 90 thousand plants ha-1. Due to the favourable ecological and agrotechnical conditions. Yields varied between 11400 and 16300 kg ha-1 depending upon the hybrid and the plant density. From among the hybrids, 5 and 7 produced the maximum yield at 70 and 90 thousand plants ha-1, respectively however the yield increment was not significant between 70 thousand plants ha-1 and 90 thousand plants ha-1. No relationship was found between the season length and the optimum plant density of hybrids. Those hybrids were the most favourable, which gave a stable high yield at different plant densities that is their optimum plant density range was wide (P 9175, P 9494, SY Afinity). Hybrids with a small optimum plant density range (P 9578, DKC 4490, PR 37N01) gave the highest yield at a specific plant density (70 thousand plants ha-1 or 90 thousand plants ha-1). A special complex coordinate system was developed for evaluation for the plant density response of maize genotypes specific ecological and agrotechnical conditions can be evaluated jointly.

Cím:Correlation of secondary salinization and soil conditioning in vegetable production under irrigation with saline water / Arzu Rivera-Garcia, Géza Tuba, Györgyi Kovács, Lúcia Sinka, József Zsembeli
Dátum:2022
ISSN:2064-7816 2064-9479
Megjegyzések:Secondary salinization is a main problem around the world due to climate change and intrusion of salts in the soil by improper irrigation. Our aim was to study the soil salinization process by simulating vegetable production under irrigation with saline water (total soluble salt content 700 mg L??1). We tested 6 different technologies of soil conditioner application and 3 vegetable crops with different sensitivity to salinity in a small plot experiment set up on a meadow chernozem soil. During the irrigation season in 2020, we regularly measured the electric conductivity (ECa) and the soil moisture content (v/v%) in the topsoil (0.1 m) and analysed these parameters with Pearson's bivariate correlation (PCC) method. As our hypothesis, we expected that there is correlation among ECa, soil moisture content, soil conditioning, and providing the possibility to quantify the secondary salinization process.We found that all the 4 biosynthetic soil conditioners technologies minimized the harmful effect of saline irrigation. In the case of the not salt tolerant (NT) peas, the PCC correlation was higher to compost application and control expressing more intense salinization. NT beans showed a weaker correlation with lower PCCs, which must be due to its higher root activity leading to intensive leaching resulting in a lower degree of salinization. In the case of chilli with low salt tolerance (LT), micro dosing of soil conditioners was not effective in mitigating the harmful effect of secondary salinization, only full doses decreased the PCC. The salt tolerance of the investigated vegetable crops was also manifested in the yields. We found that PCC is a suitable statistical method to understand and quantify the process of secondary salinization.

Cím:Abiotic stress impacts caused by weather and nutrient replenishment on the yield of maize (Zea mays L) / Széles Adrienn, Ragán Péter, Nagy János
Dátum:2017
ISSN:2064-7816 2064-9479
Megjegyzések:In the long-term experiment established by the University of Debrecen, we were examining howthe amount and distribution of yearly precipitation, as well as nutrient replenishment affect maize productivityduring the growing season in 2014, 2015 and 2016.Environmental factors have a significant impact on yield. In all examined cases, there was a significant (P<0.001)difference between crop years. The most significant difference was observed between the yield of 2015 and 2016(3475 kg ha-1, P<0.001). The growing season of 2016 - which ended with significant precipitation surplus (+110mm) - provided the availability of nutrients, thereby resulting in the highest yield both in treatments A and B.Averaged over the examined years, treatment B resulted in a non-significant yield increasing effect (603 kg ha-1)in comparison with treatment A. When evaluating the different crop years one by one, it can be concluded thatthere was a significant yield difference in 2015 (1036 kg ha-1; P<0.05) (averaged over the different fertilisertreatments), despite the fact that it was a dry year. This phenomenon is explained by the fact that the silking ofthe examined maize hybrid ended before the dry period and the unfavourable effect of weather could be reducedwith a high amount of nutrient replenishment.

Cím:Effects of carbon dioxide concentration on chlorophyll fluorescence of peas "Pisum sativum L." / András Tamás, Ágnes Törő, Zoltán Balla, Tamás Rátonyi, Endre Harsányi
Dátum:2017
ISSN:2064-7816 2064-9479
Megjegyzések:The atmospheric concentration of carbon dioxide increases from decade to decade in increasing pace. In 1957, atmospheric carbon dioxide levels were around 315 ppm, while in 2012 it amounted to 394.49 ppm concentration. The atmospheric concentration of carbon dioxide is expected to reach 550 mol-1 to mid-century. In parallel, the global temperature is rising, which is projected to average 1.5-4.5?C. These global environmental changes, directly or indirectly affect plant growth, development, yield and quality of the crop. During the research, in climate chambers, "Irina" pea was sowed, which were tested near 700 and 400 ppm carbon dioxide concentration. Chlorophyll fluorescence was measured both in dark-adapted (Fv/Fm test) and in light-adapted leaf samples (Yield test; Y(II)).
