“…The issue regarding an optimal nitrogen rate remains a topical subject in numerous studies (Malešević et al, 2010;El Metwally et al, 2010;Janković et al, 2011;Magliano et al, 2014;Tanaka and Nakano, 2019).…”

Production traits and grain quality of spring malting barley as the major raw material in malt and beer production were evaluated over a period of three years (2012)(2013)(2014) in the region of Požarevac, Serbia. Four cultivars of two-rowed spring barley released in the Republic of Serbia ('Novosadski 448', 'Novosadski 456', 'Dunavac' and 'Jadran') were used. The objective of this research was to assess variability in grain yield and yield components in genetically divergent cultivars of two-rowed spring barley grown at different nitrogen application rates, as dependent on precipitation and air temperature during the growing season. The results showed significant variations in grain yield, yield components and grain protein content across genotypes (G), N application rates (N) and experimental years (E). Significant interdependence was found between grain yield and yield components. Increasing the N application rate up to 135 kg/ha had a positive effect on grain yield, plant height, number of spikes per unit area, spike length and grain protein content. Number of grains per spike and 1,000-kernel weight increased significantly at N application rates up to 105 kg/ha and 75 kg/ha, respectively.

“…However, tiller number mostly decreases during the generative growth phase as a result of tiller abortion, a process strongly influenced by cereal crop species/cultivar, sowing density, light quality, and climate conditions [16][17][18] . Tiller formation increases with N fertilizer dose and responds to the fertilizer N form, as combined ammonium nitrate enhanced tiller number more effectively than the same amount of either N form alone [19][20][21] . The physiological basis of this N form effect relies, at least in part, on phytohormone signaling.…”

Cereal crop yield comprises interrelated components, among which the number of tillers is highly responsive to nitrogen fertilization. We addressed the hypothesis of whether the supply of different nitrogen forms can be employed to manipulate the tiller number in cereal crops. Relative to urea or ammonium, exclusive supply of nitrate increased tiller number in hydroponically-grown barley plants. Thereby, tiller number correlated positively with the root-to-shoot translocation rate of endogenous cytokinins. External supply of a synthetic cytokinin analog further stimulated tillering in nitrate-containing but not in urea-containing nutrient solution. When the cytokinin analog 6-benzylaminopurine riboside was externally supplied to roots, its translocation to shoots was 2.5 times higher in presence of nitrate than in presence of urea or ammonium, suggesting that cytokinin loading into the xylem is affected by different nitrogen forms. We then translated this finding to field scale, cultivated winter wheat in four environments, and confirmed that nitrate fertilization significantly increased tiller number in a dose-dependent manner. As assessed in 22 winter wheat cultivars, nitrogen form-dependent tiller formation was subject to substantial genotypic variation. We conclude that cytokinin-mediated signaling effects of fertilizer nitrogen forms can be employed as a management tool to regulate the tiller number in cereal crops.

“…According Wang et al (2016), SPAD values of plants under freezing stress are another good metric to measure cold damage. That proposition was later confirmed by Tanaka and Nakano (2019), who found that later sowing dates increased SPAD values.…”

In the study reported here, six forage pea cultivars Töre, Taşkent, Özkaynak, Ulubatlı, Ürünlü, and Gölyazı were examined at different temperatures 20 °C (i.e., control), 15 °C, and 10 °C and sowing dates October 1, October 15, and November 1 in Eskişehir condition, to determine their cold tolerance during germination and as early seedling stages. Results included that survival rates varied among cultivars and by sowing date, with the highest rate achieved by Töre (98.2%) and the lowest (87.9%) by Ulubatlı; however, the high survival rates of the Töre, Taşkent, Özkaynak, Ürünlü, and Gölyazı varieties did not differ significantly. Early sowing negatively affected the survival rates of the Ulubatlı and Gölyazı cultivars more than the others. Survival rate correlated negatively with plant height and number of nodes but correlated positively with SPAD value and leaf relative water content. Gölyazı achieved the highest germination rate (92.8%) and Ulubatlı the lowest (81.8%), although the high rates of the Gölyazı, Töre, Taşkent, and Özkaynak cultivars did not significantly differ. Low temperatures adversely affected all observed characteristics, and seedling lengths highly paralleled survival rates obtained in field conditions. Taken together, such findings suggest that purple-flowered cultivars tolerate low temperatures better than white-flowered ones.
