Variety Testing

В настоящее время недостаточно известны объективные потребности растений в элементах питания, об этом свидетельствуют значительные различия между максимальными и средними значениями урожайности при испытании сортов. Существенные различия урожайности связаны с тем, что не учитываются генетические особенности сортов поглощать элементы питания из почвы и удобрений. В основном, как правило, применение удобрений рассчитывается на усредненное значение по культуре, а не под возделываемый сорт. В результате сортоиспытание без учета генетически обусловленных особенностей минерального питания приводит к тому, что агрохимически активные сорта снимаются с испытания, так как для реализации их генетического потенциала не созданы соответствующие условия минерального питания. Цель работы – оценить общую и специфическую отзывчивость сортов озимой пшеницы на применение минеральных удобрений и выделить агрохимически активные формы. Для достижения цели был заложен двухфакторный полевой опыт. Фактор А – сорта озимой пшеницы, фактор В – уровни минерального питания. В результате установлено, что наиболее агрохимически активными формами являются сорта озимой пшеницы Скипетр, Клавдия 2 и Московская 56. Сорта Безенчукская 380, Немчиновская 57 и Фотинья характеризуются как формы с меньшей агрохимической активностью. At present, the objective nutrient requirements of plants are not well known, as evidenced by the significant differences between maximum and average yields in variety trials. Significant differences in yields are due to the fact that the genetic characteristics of varieties to absorb nutrients from soil and fertilizer are not taken into account. For the most part, fertilizer application is calculated as a crop average rather than for the variety being cultivated. As a result, variety testing without taking into account genetically determined features of mineral nutrition leads to the fact that agrochemically active varieties are withdrawn from testing, because appropriate conditions of mineral nutrition are not created for realization of their genetic potential. The aim of the work is to evaluate the general and specific responsiveness of winter wheat varieties to the application of mineral fertilizers and to identify agrochemically active forms. In order to achieve the objective a two-factor field experiment was laid. Factor A - winter wheat varieties, factor B - mineral nutrition levels. As a result, it was found that the most agrochemically active forms are winter wheat varieties Skipetr, Klavdiya 2 and Moskovskaya 56. Bezenchukskaya 380, Nemchinovskaya 57 and Fotinya varieties are characterized as forms with less agrochemical activity.

Winter Wheat Varieties

Nutrient removal and payback of mineral fertilizers by harvest of winter wheat varieties were studied under technologies of different intensity levels in 2012-2015. The design of the experiment included three fertilizer systems divided into three yield levels (6, 8 and 10 t/ha) adjusted for the actual content of mobile phosphorus and potassium in the soil. Samples of grain and straw were taken for each variety and technology before harvesting, nutrient content was determined. Calculation of nutrient removal was carried out at 14% moisture. Nutrient removal and payback of fertilizers by harvest of winter wheat varieties depended on genetic characteristics and cultivation technology. Nemchinovskaya and Moskovskaya varieties had the highest (17-29 kg/kg) and the lowest (39-21 kg/kg) fertilizer payback, respectively, in high-intensity technology. The lower the stem height, the lower the nutrient removal. The sum of fertilizers (NPK) used by Nemchinovskaya 24 variety was 210 kg/ha in standard technology, 330 kg/ha in intensive technology, and 450 kg/ha in high-intensity technology. Lower fertilizer costs were noted on average over the research years. Increasing intensity of technology - from standard to high-intensity - resulted in increased nutrient removal and fertilizers costs, and their payback decreased.

Cultivation Techniques

Основным направлением повышения качества зерна является выведение новых сортов, генетически предрасположенных формировать зерно с высоким качеством. Вместе с тем, генетический потенциал сортов способен реализовываться только при конкретных погодных условиях и применении приемов возделывания, благоприятно влияющих на рост и развитие растений. В настоящих исследованиях путем изменения режимов питания растений создавали различные условия для того, чтобы определить возможности сортов формировать урожай зерна с большим содержанием белка. Цель работы оценить и выделить сорта озимой пшеницы, способные реализовать потенциал качества зерна при различных уровнях интенсификации минерального питания. Для достижения цели был заложен двухфакторный полевой опыт. Фактор А сорта озимой пшеницы, фактор В уровни минерального питания. В результате установлено, что сорта озимой пшеницы характеризуются неодинаковыми свойствами накапливать белок в зерне. Высокой активностью накапливать белок при внесении удобрений характеризуется сорт Клавдия 2. Средней активностью сорта Безенчукская 380, Московская 56 и низкой Немчиновская 57, Скипетр и Фатинья. Внесение минеральных удобрений из расчета N16 P16 K16 при посеве осенью и N68 в подкормку весной способствует формированию зерна с более высоким содержанием белка у всех сортов озимой пшеницы.The main direction of improving the quality of grain is the cultivation of new varieties genetically predisposed to form high quality grain. At the same time, the genetic potential of varieties can only be realized under specific weather conditions and the application of cultivation techniques that favourably affect the growth and development of plants. In these studies, various conditions were created by changing plant nutritional regimes in order to determine the possibilities of varieties to form a grain crop with a high protein content. The purpose of the work was to evaluate and highlight varieties of winter wheat that can realize the potential of grain quality at various levels of intensification of mineral nutrition. To achieve the goal, a two-factor field experiment was carried out. Factor A - winter wheat varieties, factor B - levels of mineral nutrition. As a result, it was established that varieties of winter wheat were characterized by unequal properties to accumulate protein in grain. Variety Claudia 2 was characterized by high activity to accumulate protein when fertilizing. Bezenchukskaya 380, Moskovskaya 56 were characterized by medium activity and Nemchinovskaya 57, Scepter and Fatigna - by low. The application of mineral fertilizers at the rate of N16 P16 K16 during sowing in fall and N68 for top dressing in spring contributed to the formation of grain with a higher protein content in all varieties of winter wheat.

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.

Winter Wheat Varieties

The article shows the research on grain quality which was conducted at North- Caucasus Scientific Agricultural Center 2015-2017. The research explored the grain quality of new soft winter wheat varieties. The grain belongs to own selections of soft winter wheat, particularly to Sekletiya, Zernetko 1, Tsaritsa and Liniya 1517. The authors focus on indicating the impact of certain factors on high-quality grain. Batko variety was applied as a standard. The soil of the experimental plot was black soil; the climate was moderate continental. The forecrop was pure steam. Before sowing, the authors applied complex mineral fertilizers dosed N40P60K40; in spring the researchers fertilized them with ammonium nitrate dosed26 kgof ammonium nitrate per hectare. The authors observed positive correlation between nature and flour strength qualities of grain (0,7-0,8); inverse relationship between the value of natural mass and IIR values (-0,79); dough elasticity to dough extensibility (-0,88); and baking absorption parameter (-0,85). Flour strength depends on protein quantity and quality (r = 0.79). The wheat varieties have shown different values of flour strength: Liniya 1517 and Zernetko 1 correspond to good filler (282-294 a.), Sekletiya, Tsaritsa and Batko (standard) correspond to satisfactory improver (312, 332,345 a.). Tsaritsa variety formed gluten of the first group during three years under different temperatures. This indicates the prevalence of protein glutenin fraction and capacity of strong wheat improver. The authors found out high correlation coefficient of sedimentation with the amount of gluten (r = 0.81) was found. The quality of winter wheat grain was affected by the arid conditions of grain loading in 2015 and overwetting in 2017. This prevented the varieties from showing up their capacities.
