Winter Wheat Varieties

Winter wheat is the most important crop in Germany, which is why a three-year field trial (2015–17) investigated the effects of weather on biometric parameters in relation to the phenological growth stage of the winter wheat varieties Opal, Kerubino, Edgar. In Brandenburg, there have been frequent extreme weather events in the growth phases that are relevant to grain yields. Two winter wheat varieties were grown per trial year and parts of the experimental field areas were irrigated. In addition, soil physical, biometric and meteorological data were collected during the growing season (March until end of July). There were five dry periods in 2015, six in 2016, and two in 2017 associated with low soil moisture. Notably, in 2016 the plant height was 5 cm lower and the cover was 15% lower than on irrigated plots. The grain yield was increased by 19% and 31% respectively by irrigation. However, due to irrigation costs, the net grain yield on irrigated plots was lower than on the unirrigated plots. It turned out that in dry years there were hardly any differences between winter wheat varieties. Multiple regression analysis showed a strong correlation between the biometric parameters considered here and the grain yield.

Winter Wheat Varieties

In order to realize the maximum potential parameters of winter wheat productivity, it is necessary, first of all, to use high-yielding varieties with optimal quality indicators of grain, as well as progressive agricultural technologies aimed at obtaining a stable crop yield. Winter wheat places high demands on its previous crops. Insufficient amount of productive moisture in the soil or its extremely low reserves affects the yield, and consequently, the quality of winter wheat grain according to unpaired predecessors. Moreover, dry autumn during the sowing period leads to its delay, which is the reason for obtaining uneven and weak seedlings. In this regard, studies have been carried out to study and assess the influence of predecessors on the agrocenosis, yield and grain quality of promising varieties of Adel, Grom, Tanya winter wheat. According to the experimental scheme, peas, corn for silage and sunflower have been identified as the preceding crops for winter wheat. Agrotechnology in experience is generally accepted for the foothill zone of the Republic of Adygea. The results of the research made it possible to identify the most optimal of the considered predecessors in the cultivation of winter wheat, capable of providing stable yields with high quality grain. Certain differences in the photosynthetic activity of the studied winter wheat varieties for different predecessors have been noted. It has been found that the leaf area of winter wheat varieties is in the range of 30,0–33,5 thousand m2/ha. The highest dry matter content in the range of 4,9–5,0 t/ha is observed in the Grom variety, and the predecessor is peas. The largest number of grains in an ear for three previous crops is 40–43 pcs / ear for peas. It also had a fairly significant effect on the weight of 1000 grains and the grain yield of winter wheat. For example, the weight of 1000 grains of the most productive Thunder variety varied from 40,1 to 41,6 gm, depending on the previous crop. According to the results of the experiments, the highest grain yield of winter wheat within the range of 5,3 t/ha has been noted for the Grom variety when cultivated for peas. The smallest grain yield in the range of 3,8–3,9 t/ha is typical for all studied varieties of winter wheat, namely, according to the cultivated predecessor – sunflower.

The effects of simulated waterlogging, drought stress and their combination were examined in a model experiment in Martonvásár, Hungary, in 2018. Four modern winter wheat varieties (‘Mv Toborzó’ (TOB), ‘Mv Mambó’ (MAM), ‘Mv Karizma’ (KAR), ‘Mv Pálma’ (PAL)) and one old Hungarian winter wheat cultivar (‘Bánkúti 1201’ (BKT)) were tested. Apart from the control treatment (C), the plants were exposed to two different abiotic stresses. To simulate waterlogging (WL), plants were flooded at four leaf stage, while in the WL + D treatment, they were stressed both by waterlogging and by simulated drought stress at the early stage of plant development and at the heading stage, respectively. The waterlogging treatment resulted in a significant decrease in plant biomass (BKT, TOB), number of spikes (TOB), grain yield (BKT, TOB), water use (BTK) and water-use efficiency (TOB, MAM, PAL) compared to the controls. The combined treatment (WL + D) led to a significant decrease in plant height (BTK, MAM, KAR), number of spikes (BTK, TOB, MAM, KAR), thousand kernel weight (TOB), harvest index (BTK), biomass, grain yield, water-use efficiency (in all varieties) and water use (BKT, TOB, MAM, KAR) of the plants. The best water-use efficiency was observed for MAM; therefore, this genotype could be recommended for cultivation at stress prone areas. The varieties MAM, KAR and PAL also showed good adaptability.

Experimental researches had been carried out during 2012–2016 in the crop rotation of Sumy National Agrarian University (SNAU) of the Ministry of Education and Science of Ukraine. Soils on the experimental field of SNAU – black soil typical deep, non-humusful medium-loam with high and medium provision with elements of mineral nutrition. The humus content about 3.9 %. The reaction of the soil solution is close to neutral (5.8). The analysis of the weather conditions of 2012–2016 researches was conducted on the basis of annual data provided by the meteorological station of the Institute of Agriculture of the North-East of the NAAS, located five kilometers from the experimental field of SNAU. The SNAU soils are classified in the second agro-climatic region of the Sumy region, which according to a long-term data is characterized by temperate continental climate with warm summers and not very cold winters with thaws. Average daily (average annual) air temperature during 2012–2016 fluctuated from +7.9 to +9.5 ºС, and the legth of the frost-free period was close to 230 days. Long-term indicator, precipitation falls within 597–600 mm, with most of it – in the warm period (April-October). In general, the weather conditions during the winter wheat vegetation periods differed from the average annual parameters of the temperature regime, the amount of precipitation and their monthly distribution. It should be noted the excess of temperature to the average long-term index, as well as a slight precipitation increasing. In general, it facilitated to a comprehensive evaluation of the studied Chinese varieties as for an adaptive ability under condition of Ukraine. The samples of Chinese winter wheat varieties which originated from the expeditionary gatherings conducted by V. A. Vlasenko in Gansu and Hebei provinces in (2000–2012) were the material for conducting researches. The cultivar Podolianka (the standard) was used in the study for comparison. The research was carried out using field, laboratory and mathematical-statistical methods. Phenological observations and records, evaluation and harvesting were conducted in accordance with generally accepted methods. The results of research as for adaptive potential of Chinese bread winter wheat varieties are presented. 50 new cultivars of Chinese origin were analyzed under the conditions of left-bank side of North-East Forest-Steppe of Ukraine: super-early varieties – 10 %; early ripening varieties – 54 %; middle-early varieties – 12 %; mid-ripening varieties – 24 %. As for the level of tolerance for winter conditions, all groups of alien crops were inferior to the standard (cultivar Podolyanka) though they had a great level of index (6.4–7.9 points). In general, Chinese cultivars under the conditions of the research were characterized by relatively satisfactory tolerance for winter conditions; 52 % of analyzed patterns wintered at the level of standard with 8 points. Among them: super-early varieties – 2 %; early ripening varieties – 20 %; middle-early varieties – 8 %; mid-ripening varieties – 22 %. As for the height of the plants we identified – from medium-sized (81‒110 cm) forms to dwarf (30-50 cm). The analyzed genotypes divided into medium-sized forms – 22 %, dwarf forms – 14 % and semidwarf forms – 64 %. There was a direct relation between: a plant height → group of ripeness (r = 0.96) → group of ripeness (r = 0.92) → resistance to overwintering (r = 0.78). Among the analyzed patterns high resistance against a group of diseases had the varieties: middle-early genotypes – Longzhong 10, Zhong mai 19, Shijra zhuang 8; mid-ripening genotypes – Longzhong 1, Longzhong 3, Longzhong 2, Longzhong 4, Longzhong 12, Longzhong 7; early ripening genotypes – DF529, Lankao 906, DF581, СА0175, Zhongmai 9, Shi 4185, Jimai 22, Shixin 733, Shimai 12. As for the crop better than the standard: early ripening varieties –Jimai 19, DF529; middle-early varieties – Shijiazhuang 8, Longzhong 10, Jingdong 8; middle-early varieties – NSA 97-2082, Longzhong 2, Longzhong 4, Longzhong 7, Longzhong 5, Longzhong 8, Longzhong 12, Longzhong 11, Longzhong 3. 16 % of analyzed cultivars distinguished by the totality of researched characteristics – DF529, Shijiazhuang 8, Longzhong 3, Longzhong 10, Longzhong 4, Longzhong 7, Longzhong 12, Longzhong 2.

Abstract. Baimuratov, A, Bastaubayeva S, Arslan M, Yeraliyeva Z. 2021. Effect of fertilizer application on winter wheat productivity under precision agriculture in Kazakhstan. Biodiversitas 22: 1558-1563. The effect of mineral fertilization of light chestnut soils of Almalybak, Kazakhstan on the three winter wheat varieties grain yields and NDVI was carried out in 2017/18, 2018/2019 as well as 2019/2020 growing seasons using precision agriculture technologies. The experiments were set up in an incomplete factorial design with rates of NPK N90P60K45, N120P90K60, and N150P120K90. Agrochemical cartograms were ordered for the substance of effectively hydrolyzable nitrogen, extractable phosphorus, and exchangeable potassium. The total variation of NDVI was from 0.62 in the minimum (Bezostaya 100 variety, 2017/18) to 0.88 in the maximum (Aliya variety, 2019/20) in the flowering phase of wheat plants. The highest index of NDVI was observed in the N150P120K90 in the three winter wheat varieties for the three seasons. Studies directed in multivariate analyses built up the connection between fertilizer application, soil fruitfulness, and grain yield. As per the genuine heterogeneity of the fields, standards were determined and differential use of the fundamental phosphorus fertilizer was completed. The yield for the winter wheat varieties varied between 5.6-5.9 t/ha for Aliya variety, 6.5-7.0 t/ha for Grom, and 6.2- 6.7 t/ha for Bezostaya 100, which presents that P120 doses were more suitable in experimental plots for winter wheat varieties. The grain yield on mineral fertilization of NPK for the studied varieties varied from 4.2 to 7.6 t/ha for Aliya variety, from 4.0 to 6.8 t/ha for the Bezostaya 100, and from 4.5 to 7.9 t/ha for Grom. The highest grain yield was observed in the N150P120K90 for three winter wheat varieties in all three seasons.

The article substantiates the need to improve the elements of technology for growing varieties of soft winter wheat, taking into account the size of the seed material and weather conditions of the growing season. It is determined that along with varietal properties, the use of pre-prepared seeds for sowing has an impact on its sowing properties, field germination, growth and development of plants, their formation of elements of productivity and grain yield. The study was conducted on five registered varieties of soft winter wheat 'Tsarychanka', 'Karmelyuk', 'Sidir Kovpak', 'Dykanka' and 'Sanzhara' in the agro-climatic zone of the central part of the Forest-Steppe of Ukraine. The results of research showed that the highest field germination of seeds have the variety 'Karmelyuk' for sowing shallow and medium fraction of seeds (94 and 90%, respectively), and the variety 'Dykanka' - sowing medium and large fraction (95 and 86%, respectively). The percentage of germination of seeds of varieties 'Tsarychanka', 'Sanzhara' is almost at the same level 82 and 89, respectively. The highest indicators of elements of structure of an ear are found at the varieties 'Karmelyuk' - 30,5 pieces of grains in an ear, for its weight in an ear of 0,86 g, 'Dykanka' - 30,6 pieces of grains in an ear, for its weight in an ear 0, 87. The use of seeds of the middle fraction for sowing provided the highest yield of varieties 'Karmelyuk', 'Dykanka' which amounted to 4.7 t / ha. When sowing seeds of a large fraction, the highest yields were obtained by 'Dykanka' and 'Sanzhara' varieties - 4.8 and 4.9 t / ha, respectively. The aim of the study. To determine the influence of seed fraction on sowing qualities, variability of yield elements of soft winter wheat varieties. The experiment was conducted in the central forest-steppe of Ukraine, using general research methods studied in agronomy The material for the study were winter wheat varieties of Poltava State Agrarian Academy: "Tsarchanka", "Karmelyuk", "Sidir Kovpak", "Dykanka" and "Sanzhara". Sowing of the studied varieties was carried out with seeds selected on sieves and divided into fractions: shallow (1), medium (2), large (3), and mixture (4). Agrotechnics in the study are generally accepted for the soil-climatic zone of the Forest-Steppe of Ukraine. The increase in the weight of 1000 grains was significantly influenced by sowing with the middle fraction of seeds, which is characteristic of the variety 'Sidir Kovpak' (50.4 g), large - 'Tsarychanka' (52.5 g), 'Dykanka' (49.2 g) and 'Sanzhara' (48.4 g), for the variety 'Karmelyuk' the weight of the grain increases when sown with a mixture of seeds (52.0 g). It was determined that the size of the seed material had an impact on the elements of the structure of the ear of corn and grain size. Thus, the variety 'Tsarichanka' formed 26.8 pieces. grains in the ear, for its weight of 0.65 g when sown by the average fraction of seeds, variety 'Karmelyuk' on the same variants of the experiment, respectively - 30.5 pcs. and 0.86 g, grade 'Sidir Kovpak' - 27.4 pcs. and 0.85 g, 'Dykanka' - 30.6 pcs. and 0.86 g. For these varieties, the dependence is established: sowing in shallow and large fractions, as well as a mixture of seeds reduces the number and weight of grains from the ear. In the variety 'Sanzhara' revealed a maximum increase in the number of grains from the ear to 26.8 pieces. and the mass of grain from the ear of 0.88 g in the options for sowing a large fraction of seeds Yields of the studied varieties of winter wheat depending on the size of the seed material varied in the range from 3.08 to 4.86 t / ha, with the highest value in option 3 (large seeds) in the varieties 'Sanzhara' (4.9 t / ha) and 'Dykanka' (4.8 t / ha), on option 2 (average seed) 'Karmelyuk' (4.67 t / ha), 'Sidir Kovpak' (4.29 t / ha) and 'Tsarychanka' - 4 .0 t / ha. It was found that the yield of all studied varieties of winter wheat has a strong correlation with seed size and number of grains in the ear (r> 0.70), the average correlation between the weight of 1000 grains and grain yield was found in varieties' Tsarychanka ',' Karmelyuk 'and' Dykanka '(r = 0.31… 0.69). In the variety 'Sanzhara', the weight of the grain from the ear and the yield have a rectilinear correlation of medium strength.
