Main Directions of Use of Waste of Plant Raw Materials (Peanut Shell) as Adsorbents (Re-View)
chemistry of plant raw material
Currently, one of the major and global problems is the treatment of wastewater from organic industrial waste, such as textile waste. The solution to this problem is the production of environmentally friendly adsorbents based on plant raw materials. The increasing use of natural resources, biomass recovery, and biomass waste in the past decade, has attracted the attention of an increasing number of scientists. Activated carbon (AC), used to remove organic micro-pollutants in the world's wastewater treatment plants, is typically produced from non-renewable resources such as peat, lignite, coal, anthracite, wood materials, waste from the paper industry, leather industry, and animal substances that must be transported over long distances. The use of local residual biomass as feedstock can be beneficial in terms of sustainability. The review is devoted to the analysis of publications in this area in recent years. The main areas of application of adsorbents based on peanut shells are ...
New knowledge Journal of science, 2019
In the present experimental work was investigated the influence of mineral fertilizers, produced by Agropolychim JSC, on the main agrochemical parameters of the soil, as well as on the productivity and biochemical characteristics of two of the main winter crops in our country - wheat (“Andino” variety) and rapeseed (“PT225” hybrid). The study found a beneficial effect of the urea + ammonium nitrate and UAN variants on the macronutrient reserve in wheat, while the use of liquid nitrogen fertilizer UAN had the highest effect in rapeseed. The highest productivity in the experiment with wheat and especially rapeseed demonstrates the variant using liquid nitrogen fertilizer UAN, with the difference in yield compared to the other variants statistically proven.
Impact of Salicylic Acid and Oxalic Acid on Physiological Parameters of Wheat Plant
Bulletin of the Korkyt Ata Kyzylorda University
The issue which affected the quality and availability of wheat is not only abiotic and biotic stresses but also climate change.Approximately, a third of agricultural production is produced through out the use of pesticides. Pesticides have harmful impacts on the crops, beneficial microorganisms and the health of human beings. Thus, alternative or chemical-free methods of plant protection prevent from the risks of causing by chemicals. In this study, in order to gain constant dry weight of root an shoot, shoot and root of wheat at three leaves stage were pulled out from the soil then they are separated. In order to a get constant dry weight shoot and root of wheat in an thermostat set to 100 C for 30 minutes. Immediately after cooling, the plants were weighed on a scale. Salicylic acid rates were 0, 0.25, and 0.5 mM, and the oxalic acid rates were 0, 0.1, and 0.2 mM, which were applied via foliar vs. seed treatments. In this experiment the highest germination percentage observed in 0...

An immense increase in human population along with diminished lands necessitates the increase of rice production since, it serves the human population as a staple food. Though rice hybrids (RH) are showing considerable yield enhancement over inbreds in terms of both quality and quantity, farmers’ adoption of hybrid rice technology has been much slower than expected because of several constraints such as seed cost and quality. Doubled haploid (DH) technology was considered useful for the development of inbred lines from rice hybrids in a single generation. Androgenesis shows its significance in development of DHs in rice which requires an efficient method to establish the production of large population. To start the anther culture, anthers are the main component of androgenesis to be isolated from unopened spikes. However, the duration of spikes availability for anther culture coupled with the segregation of rice hybrids in the next generation requires the main crop be ratooned to re...
Screening for Abiotic Stress Tolerance in Rice: Salt, Cold, and Drought
Methods in molecular biology (Clifton, N.J.), 2016
Rice (Oryza sativa) is the primary source of food for more than half of the world population. Most rice varieties are severely injured by abiotic stresses, with strong social and economic impact. Understanding rice responses to stress may help breeding for more tolerant varieties. However, papers dealing with stress experiments often describe very different experimental designs, thus making comparisons difficult. The use of identical setups is the only way to generate comparable data. This chapter is organized into three sections, describing the experimental conditions established at the Genomics of Plant Stress (GPlantS) unit of ITQB to assess the response of rice plants to three different abiotic stresses-high salinity, cold stress, and drought. All sections include a detailed description of the materials and methodology, as well as useful notes gathered from the GPlantS team's experience. We use rice seedlings as plants at this stage show high sensitivity to abiotic stresses....

The full use of secondary raw materials from processing plants by biotechnological methods is economically feasible and promising for the biotechnological industry. The purpose of this study is developing technology for the utilization of rice husk to obtain nutrient medium for the cultivation of bacteria Paenibacillus, promising for the production of agricultural biological products, in particular, biological fertilizers and feed additives. The processing of rice husk by using chemical and biotechnological methods showed that optimized condition for the separation of fiber and mineral substances from rice husk is treating rice husk with sodium hydroxide with concentration 2.5% at 120 °C for 20 minutes. The possibility of obtaining simple sugars by enzymatic treatment of rice husk fiber with the enzyme preparation Accellerase 1500 for 24 hours at 55 °C was observed. Under these conditions, the enzymatic hydrolysate of rice husks contains 89% of reducing sugars of absolute dry matter...
