“…In fact the main outcome of breeding in different countries was an improved sink capacity without a corresponding increase in storage reserves or post-anthesis assimilation (source) (Rharrabti et al, 2010;Parry et al, 2011;Foulkes et al, 2011). Thus, if breeding programs continue improving sink capacity, without a corresponding increase in storage reserves or post-anthesis assimilation (source), grain weight responses in both species, but mainly in barley, will continue increasing over the years.…”

a b s t r a c t Double-cropping using the wheat-soybean sequence is a common practice in Argentina to promote the intensification of crops within rotations. However, the late release of the fields by a delayed harvest time in wheat determines soybean yield penalizations. In this context, barley could represent a better option than wheat preceding soybean in the crop rotation since there is some evidence that finishes its cycle earlier than wheat. However, it is not clear which period of barley shortens crop cycle allowing an earlier field release than wheat. The objectives of this study were to compare wheat and barley in terms of (i) field release and (ii) grain weight determination through the analysis of their physiological mechanisms. Field experiments during two consecutive growing seasons testing five different environments (three sowing dates in 2007 and two in 2008) were carried out to analyze the duration of different ontogenic periods and the attributes (dry matter and water dynamics) determining grain weight during the grainfilling period in wheat and barley. Early flowering time was the main cause of the early field release by barley as the grain filling and drying period were similar in both species. A strong relationship was found between dry matter and water dynamics in both species. Barley reached a higher maximum water content than wheat and also achieved physiological maturity with higher moisture concentration than wheat (48% and 39%, respectively). Barley showed a slight increase in grain weight, respect to wheat, due to a source:sink ratio enhancement (4% and 9% for wheat and barley, respectively). These data show an opposite response to that of Mediterranean, Australian and UK environments, where barley was under stronger sink limitation than wheat during the grain-filling period.

“…Среди агротехнических приемов (предшественник, обработка почвы и др.) в получении полноценных всходов зерновых немаловажное значение имеет посев (Chen et al, 2010;Eberbach, Pala, 2005;Foulkes et al, 2011;Naresh et al, 2012). Задача посева состоит в получении дружных всходов посредством оптимального использования способа, срока посева, нормы высева, глубины заделки и распределении семян, ширины междурядий (Chen et al, 2010;Liang et al, 2011;Pandey et al, 2013;Shah et al, 2006).…”

“…При этом, максимальная средняя полевая всхожесть получена на посевах, высаженных долотообразным сошником (71,2%), а минимальная -стрельчатой лапой (64,7%). Потенциал урожайности зерновых культур зависит от продуктивной кустистости растений, числа продуктивных стеблей на 1 м 2 , количества зерен в колосе и массы 1000 зерен, что подтверждается рядом исследователей (Connor, Mínguez, 2012;Foulkes et al, 2011;Hochman et al, 2009;Malik et al, 2009;Sharma et al, 2007;Soltani, Hoogenboom, 2007;Zwart et al, 2010).

Effect of sowing techniques on the agroecological parameters of cereal crops

In Western Siberia, the problem of obtaining full-fledged sprouts of cereal crops is due to hydrothermal conditions in the period of sowing-shoots, pests and diseases, and agronomical methods of sowing. In case of the direct sowing of cereal crops, the most common types of working organs of sowing machines are the V-sharped coulter, chisel and disc. The effectiveness of their use in the dry steppe of the Altai Territory has been poorly studied. To establish the most effective seed coulter in 26 farms in the dry part of the region, the studies were carried out from 2005 to 2012 on seeders with double disc coulters, with V-sharped coulters of domestic and foreign production, and with chisel-type coulters. The years of research (2006)(2007)(2008)(2009)(2010)(2011) were characterized by a moisture supply below the average (vegetation rainfall was 80% of the norm), and in 2012 -as an acute drought (40% of the norm). The most effective seeders in the cultivation of spring wheat in the dry steppe are seeders equipped with chisel-type coulters. They allow better preservation of soil moisture (by 17-28 mm to control) during the sowing period, improving the quality of crops, field germinating by 4.8 -12.0%, and increasing the yield of wheat. In the arid year of 2012, it amounted to 1.26 t/ha after fallow, 0.88 t/ha after peas, 0.46 t/ha after wheat, respectively, at 0.64, 0.59 and 0.25 t/ha for control (two-disc coulter SZP-3,6). Seeders with V-sharped coulters of domestic and foreign production, for wheat yields did not differ significantly, but exceeded the control under the conditions of the arid year by 0.21-0.59 t/ha, depending on the forecrop.
