“…However the trigger of certain osmolytes that is low in molecular weight and high in water-solubility such as trehalose, proline, glycinebetaine and antioxidative enzymes i.e. catalase (CAT), superoxide dismutase (SOD), ascorbate peroxidase (APX) has shown their potential to protect the plant from the damage that occurs due to drought (5)(6)(7)(8).…”

Drought is a well-known issue in plants and it occurs when plants do not receive enough water to meet their requirements. Hence it alters the metabolic process of the plant, consequently reducing the yield. To overcome the loss of yield under prevailing situations, triggering of the antioxidative defense system is required which can mitigate the impact of drought on plants. The priming chemicals KNO3, Mg(NO3)2 and GA3 were evaluated with hydro-priming to know the mitigative response of priming against drought-induced stress in Maize plants. The morpho-physiological and biochemical parameters were used to evaluate the impact of priming-mediated triggers on the antioxidative response. The results of this work indicate that leaf area index (LAI), crop growth rate (CGR, mg g-1 day-1), total chlorophyll, and chl‘a’ (mg g-1) were recorded maximum in T5 (Mg(NO3)2, 10 mM) while chl ‘b’ in T4 (Mg (NO3)2, 7 mM). The maximum Membrane Stability Index (MSI %) and Membrane Injury Index (MII%) were recorded in T5 and T0 (Control). The osmoregulatory compound proline content (µg g-1) and antioxidative enzyme catalase (nm H2O2 mg-1 min-1) were detected in significantly highest quantity in T3 (KNO3, 15 mM) while the least amount of malondialdehyde (MDA nm g-1) was found under the same treatment. The correlation studies amongst all the parameters reflected that MII % and MDA content (MDA nm g-1) negatively correlated with the remaining parameters studied. This study has reflected that out of all the sources of priming treatments, KNO3 in 15 mM and Mg(NO3)2 in 10 mM has the potential to trigger the antioxidative defense mechanism to mitigate the response of drought in Maize.

“…In previous decades, single-seed precise sowing was used to simplify the process of maize production, saving the trouble of plant thinning. 30,31 This sowing method required high-quality seed to ensure the expected plant density. Previous research showed that a seedling emergence ratio up to 90% in a field could maintain the expected grain yield for most maize hybrids.…”

BACKGROUND The correct time for harvesting is a key factor contributing to the production of high‐quality maize seeds. We conducted field experiments to harvest seeds at 11 developmental stages for 3 years, to investigate seed vigor traits in three early maturity maize varieties and two late maturity varieties in one location. RESULTS Significant correlations (r = 0.72 ~ 0.89) were found among six seed‐related traits: standard germination (SG), accelerated aging germination (AAG), cold test germination (CTG), hundred‐seed weight (HSW), seed moisture content (SMC), and ≥ 10 °C accumulated temperature from pollination to harvest (AT10). Analysis of variance showed that harvest stage, year, and variety had significant effects on all traits, and harvest stage displayed the greatest effect. The responses of SG, AAG, CTG, HSW and SMC to harvest stage fitted quadratic models, and AT10 fitted a linear model. From the quadratic models, an ideal harvest time (IHT, the final date to reach maximum SG, AAG, and CTG) could be calculated for each variety. The three early maturity varieties reached their IHT at 54.94–58.44 days after pollination (DAP); the two later maturity varieties reached IHT several days later (at 59.87–59.90 DAP). The early maturity varieties consistently required less AT10 to reach the IHT than the later maturity varieties. However, all of the varieties reached the IHT at similar SMC levels of about 35%. CONCLUSION The later maturity varieties reached the IHT at later DAPs when they acquired more AT10 than the early maturity varieties but both reached it at similar SMC levels. © 2022 Society of Chemical Industry.

Background: Western Siberia has great potential for crop and livestock production; it is limited by degradation of soil fertility due to depletion of biophilic elements, including Mg. Intensification of agricultural production requires monitoring and optimization of magnesium nutrition of field crops. This study aimed at investigating changes in content of magnesium forms Gleyic Chernozems and Luvic Greyzemic Phaeozem in the Western Siberia during their long-term agricultural use. Methods: Soil samples were taken from the fields of long-term experiments in 1978, 1988 and 2019. Three cores were taken from a soil layer 0-20, 20-40 cm thick and combined into composite samples. Composite samples were kept in the archives of the institute. Chemical analysis of composite soil samples was carried out in 2020. Chemical analyzes of soil and plants were carried out by conventional methods. Magnesium forms were extracted: easily exchangeable with 0.0025 M CaCl2 solution, exchangeable with 1 M CH3COONH4, non-exchangeable with 1 M HNO3 and determined on an atomic absorption spectrometer. Result: Systematic use of the ammonia form of nitrogen fertilizers (60-120 kg a.m./ha per year) led to a decrease in mobile forms of magnesium in the most root-inhabited soil layer. The removal of magnesium by potatoes was small (8-10 kg/ha, 80 % falls on the tops). Consequently, a significant decrease in the reserves of magnesium available to plants in soils is associated not so much with the alienation of the element with yield, but with leaching processes due to the displacement of magnesium from the soil-absorbing complex by ammonium ions introduced with fertilizers and also, probably, potassium.
