Research Period

The aim of this research was to investigate the effect of spring wheat cultivars on soil properties. In 2017 the experiment was conducted at Kastytis Andriulis’s farm located in Užguriai Village, Vaiguva Eldership, Kelmė District. Three cultivars of spring wheat were selected for this research: ‘Vanek’, ‘KWS Akvilon’ and ‘Rospuda’. The ‘Vanek’ cultivar was chosen as a control. The soil type is defined as Dystric Albeluvisols. Different cultivars of spring wheat unequally affected the soil humidity and temperature. During the research period, the largest CO2 emission was determined in the ‘KWS Akvilon’ crop. Different cultivars of spring wheat had no significant impact on the soil pHKCl. Increased levels of net nitrogen, mobile phosphorus and potassium were detected in the soil after the harvest of ‘Rospuda’ and ‘KWS Akvilon’ cultivars.

In 2011–2015, at the Rumokai Experiment Station of the Lithuanian Research Centre for Agriculture and Forestry research was carried out with spring wheat on Bathihypogleyi-Calc(ar)ic Luvisol (LVk-gld-w) with predominant silt loam ant clay loam. The main aim was to determine the influence of climate conditions and fertilizer rates calculated by different methods on spring wheat. Five years of research have shown that using the Fertilization Program “Derlius” of the Agrochemical Laboratory at the Lithuanian Research Centre for Agriculture and Forestry, during spring wheat fertilization the nitrogen fertilizers were less consumed by 15.8%, phosphorus by 81.9% and potassium by 41.1% compared with fertilization for obtaining the planned 5 t ha–1 spring wheat grain yield. Also, the studies have shown that climatic conditions in the eastern part of the Baltic Sea greatly affect the yield of spring wheat. The yield of wheat grain and straw, and the number of productive stems correlated with the amount of precipitation and the sum of active temperatures in spring wheat BBCH 21–37 growth stages. A negative correlation was established in the growth stages BBCH 61–89 between higher rainfall and spring wheat yields. The average data from the five years of research showed that the sum of active temperatures during wheat growth increased nitrogen, phosphorus and potassium in the straw, and phosphorus and potassium concentrations in the grain.

Crop N Uptake

Nitrogen availability to a spring wheat crop was examined in the cropping season in a side-by-side comparison of no-till (first year) and tillage fallow in an undulating farm field in the Brown soil zone in southwestern Saskatchewan. Thirty different sampling points along a grid in each tillage landscape were randomly selected, representing 10 each of shoulder, footslope and level landscape positions. Nitrogen availability was studied i) by profile inorganic N content ii) by crop N uptake and yield of spring wheat (Triticum aestivum L.) and iii) by 15N tracer technique and in situ burial of anion exchange resin membranes (AEM).Pre-seeding available moisture content of the surface soil samples was significantly higher under no-till compared with tillage fallow. However, no significant differences in pre-seeding profile total inorganic N, crop N uptake and yield were observed between the treatments. At the landform scale, shoulder positions of the respective tillage systems had lower profile inorganic N, crop N uptake and yield compared with other slope positions. Soil N supply power, as determined by 15N tracer and AEM techniques, was not significantly different between the tillage treatments, indicating that N availability is not likely to be greatly affected in initial years by switching to no-till fallow in these soils under normal moisture conditions.

Soil samples (n = 11) were collected in the chernozem areas of the Czech Republic (the Central Europe) from the topsoil and used as representative samples. All sampling areas have been used for agricultural purposes (arable soil) and they were selected as typical representatives of agricultural soil. These samples represented the soil with same genesis (to reduction differencies between soil types) but with different soil properties (physical and chemical). Complete chemical and physical analyses were made for confirmation of copper adsorption on solid phase: we analysed the particle size distribution, content of oxidizable carbon (Cox), the cation exchange capacity (CEC), supply of exchange calcium, magnesium, sodium, phosphorus and potassium, soil reaction and the total supply of Fe, Al, Mn, Ca, Mg, K, P and N. The strongest simple correlation between analysed soil properties and copper concentration had content of available magnesium (r = 0.44) and available phosphorus (r = −0.51). In the case of multiple correlations (i. e. collective influence of multiple soil properties) had the strongest influence combination of clay, soil reaction, total content of phosphorus, available magnesium and available phosphorus. The main influence of phosphorus and magnesium is evident. We suppose that copper and phosphorus enter into specific complex. Influence of these five soil properties can explain 92.7 % (r = 0.927) changes in the content of copper changes in the experiment.

The research has been carried out under production conditions on light gray forest soils with light particle-size composition at an area of 550 hectares where liquid pig manure (LPM) of a large pig breeding complex is annually used as an organic fertilizer at doses of 60 and 90 t/ha. The average characteristics of LPM are as follows: dry matter content is 9.5%, pH 7.7 units, nitrogen 0.22%, phosphorus 0.11%, and potassium 0.12%. The cultivated grain crops were presented by winter and spring wheat varieties, Moskovskaya 39 and Esther, respectively. It has been established that at the dose of 60 t/ha LPM for two years of research at an average a mean wheat yield was 3.0-3.75 t/ha, and at the dose of 90 t/ha - up to 4.75 t/ha. The return on investments for fertilizers in the “winter wheat → spring wheat” crop rotation link at the dose of 60 t/ha of LPM was 5.41 kg of grain per 1 kg of active substance of manure, at the dose of 90 t/ha - 4.57 kg / kg. A positive balance of nutritional elements developed on all fields, but it was better balanced when the dose of LPM was 60 t/ha and the yield was 3.0 t/ha of grain annually, or when the LPM dose was 90 t/ha and the yield of wheat was 4.75 t/ha. In this case, the estimated potassi-um supply of soil occurs at a lower rate than that of nitrogen and phosphorus. The application of 120 t of LPM during two years in total on loamy sand and of 180 t/ha on light loamy soil provided an increase in the content of mobile phosphorus compounds by 5-22 mg/kg, and potassium - by 11-30 mg/kg with a variation coefficient of 28-57% and 21-49%, respectively.

Abstract To study the effect of sodium Selenite application different methods on the yield of spring wheat varieties, depending on the conditions of water supply, a series of vegetation experiments in accordance with the methodology were carried out. The object of the study is spring wheat of the Zlata variety (Triticum aestivum L.). It was found that the effect of selenium on the yield of wheat of the Zlata variety depended on the method of its application and the conditions of water supply. With optimal water supply, the positive effect of selenium on the yield of spring wheat plants was revealed with both methods of applying sodium selenite. It was found that in conditions of drought, the positive effect of selenium was obtained with both methods of using sodium selenite. The greatest efficiency of selenium is obtained in foliar processing of plants. The increase in grain weight in this variant was 1.4 times. The increase in the share of the agronomic significant part of the wheat crop yield to 36% is shown, which indicates the decrease in the negative effect of drought on the formation of spring wheat yield when using foliar processing of plants.
