Исследования проведены в условиях полевого опыта на дерново-подзолистых супесчаных почвах в 20162017 годах и заключались в выявлении потенциальной урожайности сортов сои северного экотипа и определении эффективности действия ростостимулирующих препаратов в агроклиматических условиях Калужской области. Объектами исследований были сорта сои Магева, Светлая и Касатка. В последнее время в растениеводстве для подавления фитопатогенной микрофлоры доказана возможность применения в низких концентрациях солей серебра. На растениях применяют серебросодержащие препараты коллоидные растворы, содержащие наноразмерные частицы металлического серебра, широкого спектра биологического действия. Регулятор роста Зеребра Агро , применяемый в исследованиях на культуре сои, создан на основе коллоидного серебра. Его положительное действие в первую очередь определяется влиянием ионов серебра на растения за счёт ингибирования отклика клеток на фитогормон этилен, что приводит к соответствующим изменением баланса физиологических процессов. Применение регулятора роста Зеребра Агро для обработки семян и вегетирующих посевов сои позволило увеличить высоту растений в среднем за 2 года на 23 см, площадь листьев в фазу налива семян на 2,78,8 тыс. м2/га, урожайность семян на 0,10,23 т/га, содержание белка на 2,03,7, а содержание жира на 0,10,3 в сравнении с контролем. Показано действие регулятора роста Зеребра Агро на повышение устойчивости растений сои к неблагоприятным факторам внешней среды, болезням, а также на рост и развитие растений, продуктивность сои и качество продукции. The investigation took place in 20162017 on sod-podzolic sandy soil. The goal was to determine a potential productivity of northern soybean varieties and an effectiveness of growth regulators in the Kaluga region. Soybean varieties Mageva, Svetlaya and Kasatka performed as objects of the study. Lately Crop Production showed that low concentrations of Ag salts negatively affect phytopathogenic microflora. Plants get treated by silver-containing preparations colloidal solutions containing Ag nanoparticles of wide spectrum of biological action. Growth regulator Zerebra Agro is based on colloidal silver and used on soybean. Ag slows down plant cell response in the presence of ethylene changing the chain of physiological reactions. Treatments of soybean seeds and plants with Zerebra Agro increased plant height by 23 cm for 2 years, leaf surface at seed formation time by 2.78.8 thousand m2 ha-1, seed yield by 0.10.23 t ha-1, protein content by 2.03.7, fat concentration by 0.10.3. This paper also reports on the effect of Zerebra Agro on soybean resistance to abiotic and biotic stresses as well as plant growth, yield and quality.

Fallen Leaves

Emodin, a secondary metabolite of many plants, has a wide spectrum of biological action on various groups of organisms, but the mechanisms of its action on plants are practically not studied. There is an assumption that emodin plays a certain role in allelopathy, getting into the soil with fallen leaves in the form of glycosides, which break down into emodin aglycones and are stored in the ecosystem. The aim of the study was to establish the effects of emodin on growth processes and its effect on heme-containing enzymes. It was found that emodin has an inhibitory effect on the root system of Allium cepa, and also promotes the activation of catalase activity in the roots. When studying the direct action of emodin on the activity of the catalase enzyme in vitro, it was found that the activity of the catalase enzyme decreases under the action of emodin. When studying the possible mechanisms of inactivation, it was found that emodin can interact with heme. Further detailing of the patterns of biological action of emodin will expand the scope of its application in plant protection, crop production, and also determine its role in plant ecology and physiology.

Silicon is a beneficial element as it can significantly improve the growth, yield and quality of fruit crops through silicon-enhanced resistance to biotic and abiotic stress. Mechanisms involved in alleviation of abiotic and biotic stresses are stimulation of antioxidant system in plants, complexation or co-precipitation of toxic metal ions with Si, immobilization of toxic metal ions, exclude uptake of toxic metal ions and vacuolar compartmentation of metal ions. The ignorance of plant physiologists is because of the visible symptoms of either Si deficiency or toxicity are not apparent and because of the abundance of the element in nature. Whereas, repeated cropping and the constant application of chemical fertilizers such as nitrogen, phosphorus and potassium have depleted the amount of Si that is available to plants in the soil. Awareness of Si deficiency in soil is now being recognized as a limiting factor for crop production and application of silicon fertilizer is practised worldwide, however there is limited case study regarding use of silicon fertilizer in our country despite its many advantages.

Soil salinity and sodicity are among the main problems for optimum crop production in areas where rainfall is not enough for leaching of salts out of the rooting zone. Application of organic and Ca-based amendments have the potential to increase crop yield and productivity under saline–alkaline soil environments. Based on this hypothesis, the present study was conducted to evaluate the potential of compost, Ca-based fertilizer industry waste (Ca-FW), and Ca-fortified compost (Ca-FC) to increase growth and yield of maize under saline–sodic soil conditions. Saline–sodic soil conditions with electrical conductivity (EC) levels (1.6, 5, and 10 dS m−1) and sodium adsorption ratio (SAR) = 15, were developed by spiking soil with a solution containing NaCl, Na2SO4, MgSO4, and CaCl2. Results showed that soil salinity and sodicity significantly reduced plant growth, yield, physiological, and nutrient uptake parameters. However, the application of Ca-FC caused a remarkable increase in the studied parameters of maize at EC levels of 1.6, 5, and 10 dS m−1 as compared to the control. In addition, Ca-FC caused the maximum decrease in Na+/K+ ratio in shoot up to 85.1%, 71.79%, and 70.37% at EC levels of 1.6, 5, and 10 dS m−1, respectively as compared to the control treatment. Moreover, nutrient uptake (NPK) was also significantly increased with the application of Ca-FC under normal as well as saline–sodic soil conditions. It is thus inferred that the application of Ca-FC could be an effective amendment to enhance growth, yield, physiology, and nutrient uptake in maize under saline–sodic soil conditions constituting the novelty of this work.

Abstract In the present era, due to the increasing incidence of environmental stresses worldwide, the developmental growth and production of agriculture crops may be restrained. Selenium nanoparticles (SeNPs) have precedence over other nanoparticles because of the significant role of selenium in activating the defense system of plants. In addition to beneficial microorganisms, the use of biogenic SeNPs is known as an environmentally friendly and ecologically biocompatible approach to enhance crop production by alleviating biotic and abiotic stresses. This review provides the latest development in the green synthesis of SeNPs by using the results of plant secondary metabolites in the biogenesis of nanoparticles of different shapes and sizes with unique morphologies. Unfortunately, green synthesized SeNPs failed to achieve significant attention in the agriculture sector. However, research studies were performed to explore the application potential of plant-based SeNPs in alleviating drought, salinity, heavy metal, heat stresses, and bacterial and fungal diseases in plants. This review also explains the mechanistic actions that the biogenic SeNPs acquire to alleviate biotic and abiotic stresses in plants. In this review article, the future research that needs to use plant-mediated SeNPs under the conditions of abiotic and biotic stresses are also highlighted.

Groundwater arsenic contamination has become a threat to the crop production potential in the soils of vast areas of Bangladesh. Situation is grave in some districts of the country, particularly the southern part. A pot experiment was conducted to investigate the effects of arsenic treated irrigation water (0, 1, 2, 5 and 10 mgL-1), where a total of ten (10) irrigations were provided thus the treatments received 0, 10, 20, 50, and 100 mg arsenic (As) pot-1. Effects of applied levels of arsenic on Amaranthus gangeticus (Lal shak) were evaluated in terms of the growth, yield, major nutrients’ content, and their translocation in the plant. As treatments significantly reduced (p≤0.05) the dry weight of shoot and root by 19.31% and 44.03% respectively. Both total and available concentrations of nitrogen (N), potassium (K) and sulfur (S) were significantly (p≤ 0.05) suppressed by the As treatments, while only higher three doses significantly (p≤ 0.05) affected both levels of concentrations of phosphorus (P), calcium (Ca) and magnesium (Mg). Translocation coefficients for soil to root for P, K, S, and Mg were significantly reduced (p≤ 0.05), while translocation coefficients for root to shoot were significantly increased (p≤ 0.05) for K and S by 5 and 10 mgL-1 of arsenic treatments.Bangladesh J.

Appropriate application of organic materials to agricultural soil is considered to be a valuable alternative to landfills or incineration and a good management practice for maintaining soil fertility and sustainable crop production. This study was performed to evaluate the potential use of five organic materials (peat moss, bran coat, asparagus residue, turf clipping and soybean residue) as soil amendments and/or fertilizers for greenhouse cucumber production. Each organic material was applied to greenhouse soil at the rate of 7.5 t ha-1. The application of organic materials to the greenhouse soil produced an improvement in the soil properties as well as in the cucumber growth, yield and quality, especially low-cost asparagus residues, turf clipping and soybean residues. Nevertheless, these improvements depended on the chemical composition of organic materials. In particular, all organic materials significantly increased soil potassium content. Asparagus residues significantly increased soil phosphorus content. This study demonstrated that asparagus residues, turf clipping and soybean residues were suitable for use as soil amendments and/or fertilizers for greenhouse cucumber production in terms of economic evaluation.

Lack of documentation on past harvest fluctuations limits the exploration of long-term trends in crop production and agricultural adaptation strategies. A long-term perspective is needed, however, to understand the wide spectrum of potential human responses to environment and climate change. Therefore, we used tree-ring density series as proxy data to reconstruct climate-mediated yield ratio (harvested grain in relation to sown) in central and northern Finland over the period ad 760–2000. The reconstruction explains 50% of the variance in recorded yield ratio variability over the calibration period (ad 1866–1921). The reconstruction illustrated several intervals of increased and reduced yield ratio over the past 13 centuries. The long-term development of the agricultural prerequisites is characterized by distinct intervals defined statistically as ad 760–1106 (highest yield ratios), 1107–1451, 1452–1694, 1695–1911 (lowest yield ratios) and 1912 onwards. The results provide insight into the establishment and development of crop cultivation in the agricultural margin. The reconstruction suggests that continuous crop cultivation was established in the study region during a favourable period of climatic conditions supporting high yields. Thereafter, the climate-mediated yield ratio declined in the long run until the turn of the 20th century. Periods of agricultural transformations, those previously demonstrated in pollen data and historical documents, followed the onsets of the low yield ratio phases indicated by our reconstruction. Thus, we suggest that ever since the establishment of crop cultivation, climate can be considered as an important factor contributing to the development of the agricultural history in the north.

Bare-root transplants received from high latitude nurseries for Florida production have limited root systems, very long petioles and wilt soon after planting. Further dessication occurs when leaves come in contact with black plastic mulch used in the annual production system. Conventional irrigation practices for the establishment of bare-root transplants of strawberry consist of overhead water application for at least 8 hours/day for 10-14 days after planting. Plant growth regulators (PGRs) have been used to modify the growth characteristics of many plants species. A split-block experiment was implemented at the GCREC-Dover, Dover Fla., to determine the effect of the use Prohexidione-Ca (PC) and IBA [(indole-3) butyric acid] on growth, yield and establishment of strawberry. Main blocks consisted of over head establishment irrigation for 4, 8, and 12 days, and sub-plots consisted of treatments of PC applied in the nursery at a rate of 62.5 mg·L-1 2, 4, or 6 weeks before digging, PC applied in the nursery at 31.25 mg·L-1 2 weeks before digging, a root dip of transplants in 100 mg·L-1 IBA just prior to transplanting. The experiment was conducted for four growing seasons. Data were recorded for marketable yield, number of marketable berries (>10g), and disease incidence. Significant differences were detected for duration of establishment irrigation and growth regulator treatment. No interaction was shown between establishment irrigation and growth regulator treatment.

Coriander is second most important seed spice crop grown for its seed as well as leaves. Among the major yield determining factors, NPK fertilization along with correct supply of water play an important role in the quality and yield aspects of coriander. Since coriander is grown mainly in arid and semi-arid areas, water is one of the main constraints in crop production as these growing areas are deficit in annual rainfall. Coriander grown particularly during winter season requires assured irrigation for successful production. Also, dumping of huge quantity of fertilizers in the soil becomes uneconomical besides polluting the environment. Therefore, application of optimum dose of fertilizers not only increases the yield but also improves the quality of the crop as well as soil. Extensive research work has been reported on irrigation and fertilizer requirement of coriander. Therefore, an attempt is been made to review the information available regarding the irrigation and fertilization studies and their impact on growth, yield and other attributing parameters of coriander.
