Bioenergetic characteristics of quantitative and qualitative properties of sweet sorghumhybrids are provided on the basis of a comprehensive study under conditions of cultivationon reclaimed lands. The results of studying the growth and yield characteristics of hybrids ofdomestic and American selection during four years from 2016 to 2019 under the conditions of thePokrov educational and scientific station of land reclamation DSAEU are presented. The height ofthe crop stands varied from 235.3 to 300.0 cm when growing sweet sorghum on various substratesof mining formations. The lowest yield of green biomass was observed mainly on gray-green clay(38.1 t/ha), and the highest – on loess-like loam (101.0 t/ha). Fertililizing with nitrogen fertilizerand biohumate by fertigation helped to strengthen vertical growth, increase the yield of greenbiomass and sweet sorghum grains. The greatest effect was obtained for American hybrids. ForUkrainian hybrids, the application of nitrogen fertilizers had a positive effect on black soil andloess-like loam while the effect of biohumate was noticed only on loess-like loam. Long-termresearch of the sweet sorghum hybrids allowed us to evaluate the studied objects by the level ofpossible production of green biomass and theoretical bioethanol. Ukrainian hybrids Medove andZubr using allow to produce on marginal lands from 3600 to 4250 l/ha of ethanol. The potential ofAmerican hybrids SS506 and Mohawk is slightly lower – 3150–3400 l/ha. Fertigation with nitrogenfertilizer increases the yield of theoretical ethanol from 27% to 68%, irrigation and additionof biohumate – from 15% to 36%

Background Sweet sorghum bagasse (SSB), comprising both a dermal layer and pith, is a solid waste generated by agricultural activities. Open burning was previously used to treat agricultural solid waste but is harmful to the environment and human health. Recent reports showed that certain techniques can convert this agricultural waste into valuable products. While SSB has been considered an attractive raw material for sugar extraction and the production of value-added products, the pith root in the SSB can be difficult to process. Therefore, it is necessary to pretreat bagasse before conventional hydrolysis. Methods A thorough analysis and comparison of various pretreatment methods were conducted based on physicochemical and microscopic approaches. The responses of agricultural SSB stem pith with different particle sizes to pretreatment temperature, acid and alkali concentration and enzyme dosage were investigated to determine the optimal pretreatment. The integrated methods are beneficial to the utilization of carbohydrate-based and unknown compounds in agricultural solid waste. Results Acid (1.5−4.5%, v/v) and alkali (5−8%, w/v) reagents were used to collect cellulose from different meshes of pith at 25–100 °C. The results showed that the use of 100 mesh pith soaked in 8% (w/v) NaOH solution at 100 °C resulted in 32.47% ± 0.01% solid recovery. Follow-up fermentation with 3% (v/v) acid and 6.5% (w/v) alkali at 50 °C for enzymolysis was performed with the optimal enzyme ratio. An analysis of the surface topography and porosity before and after pretreatment showed that both the pore size of the pith and the amount of exposed cellulose increased as the mesh size increased. Interestingly, various compounds, including 42 compounds previously known to be present and 13 compounds not previously known to be present, were detected in the pretreatment liquid, while 10 types of monosaccharides, including D-glucose, D-xylose and D-arabinose, were found in the enzymatic solution. The total monosaccharide content of the pith was 149.48 ± 0.3 mg/g dry matter. Discussion An integrated technique for obtaining value-added products from sweet sorghum pith is presented in this work. Based on this technique, lignin and hemicellulose were effectively broken down, amorphous cellulose was obtained and all sugars in the sweet sorghum pith were hydrolysed into monosaccharides. A total of 42 compounds previously found in these materials, including alcohol, ester, acid, alkene, aldehyde ketone, alkene, phenolic and benzene ring compounds, were detected in the pretreatment pith. In addition, several compounds that had not been previously observed in these materials were found in the pretreatment solution. These findings will improve the transformation of lignocellulosic biomass into sugar to create a high-value-added coproduct during the integrated process and to maximize the potential utilization of agricultural waste in current biorefinery processing.

Technogenic Wastes

The northeastern part of the Lesser Caucasus encompasses the western part of the Republic of Azerbaijan and is characterized with a prevalence of unique flora and fauna and the availability of rich natural resources, particularly metals. It is known that the long-term exploitation of these resources by surface mining has led to technogenic contamination in the area. Exploitation of ore deposits is associated with the origination of huge hills of waste which cause heavy degradation of pastures, forests, and croplands. A significant part of widely degraded areas in the northeastern Lesser Caucasus is found in the territory of the Gedabek administrative district. This paper deals with the problem of restoration for contaminated lands formed due to raw material extraction on territory of valuable mountain forests and meadows over a long historical period as well as the use of collected technogenic wastes for different purposes (e.g. in land reclamation, construction of motorways etc.).

Corn (Zea mays L.) is a common food and feed product in the community since it is commonly used as rice substitution as food staple. Fertilizer application is required to attain crop high yields. Plants can receive nutrients from synthetic nitrogen fertilizers (NF) during their growth cycle. However, excessive use of NF might harm the environment. Organic chicken manure (CM), on the other hand, can minimize the harmful impact of NF. Chicken manure benefits to improve the soil’s physical, chemical, and biological properties. To boost maize plant growth and productivity, might employ CM and NF. The objective of this study was to determine the effect of NF and CM on corn growth and yield. This research was conducted in Kembang Seri, Central Bengkulu, Indonesia from November 2019 to February 2020 using Randomized Complete Block Design (RCBD) with two factors and three replications. The first factor was NF doses (100, 125, and 150 %), and the second-factor consisted of CM doses (0, 10, and 20 tons/ha). Data were analyzed using ANOVA F-5%. On shoot dry weight of corn cultivated in a double row cropping pattern, there was an interaction between the dose of N and chicken manure. At 0 tons/ha, the optimum N fertilizer dose for chicken manure is 135.96 %, or 407.86 kg urea/ha. At a dose of 20 tons/ha, the optimum N fertilizer dose for chicken manure is 141.22 %, or 423.65 kg urea/ha. In a double row cropping pattern, different nitrogen fertilizer doses had no effect on corn growth and yield. The optimal dose of chicken manure was 16.65 tons/ha for plant height, 17.35 tons/ha for stem diameter, 18.89 tons/ha for leaf greenness, 17.35 tons/ha for cob length, 15.01 tons/ha for cob weight, 18.87 tons/ha for dry seed weight/plant, and 19.74 tons/ha for dry seed weight/plot.

The aim of the work is to study the effectiveness of the use of trace elements on potato varieties of different ripeness groups in the northern forest-steppe Ob in the Novosibirsk region. Experimental data were obtained on leached black soil of Novosibirsk region in 2017–2019. The generally accepted technology of potato cultivation was used for the experiments. Since autumn, fertilizers at a dose of P90K90 were applied as a general background for potatoes. Nitrogen fertilizers (60 kg / ha) were applied in the spring for pre-sowing cultivation. Foliar dressing with microelements (Cu, B, Zn) was used at the beginning of the budding phase of potato plants: copper – 20, boron – 45, zinc – 50 g of active ingredient per 1 ha with a working fluid consumption of 300 l/ha. Trace elements increased the growth and development rates of potato varieties of three groups of ripeness. In varieties Liubava (early), Svitanok Kievsky (mid-early), Tuleevsky (mid-season), the use of trace elements contributed to an increase in the development indicators of the photosynthetic apparatus (maximum and average leaf area and plant productivity) by an average of 21%, especially against the background of boron and zinc. Foliar dressing of potatoes increased the yield parameters by an average of 24 % relative to the control (water). The increase in the marketability of tubers reached 12 %. A greater effect was achieved against the background of boron use: a significant increase in yield, dry matter, starch, vitamin C. In variants with microelements, the susceptibility of potatoes by rhizoctonysis decreased.

Indoor vertical farming offers great opportunities regarding a sustainable and consistent production of high-quality herbs and raw materials all year round for the perfume, chemical, or food industry. Cultivation takes place in an enclosed structure, operating predominantly independent from external conditions in multi-layer systems equipped with artificial lighting, enabling extremely high resource use efficiencies with a simultaneous increase in yield. On the other hand, field production in terms of plant quality and harvesting times is highly influenced by environmental conditions, making it difficult to maintain homogenous raw material qualities throughout the year. To show how different light qualities affect the overall efficiency and quality of Origanum majorana grown in an indoor farm, the resource consumption, yield, and cultivation time as well as the essential oil quantity was analyzed, and the efficiencies in terms of energy and land use efficiency calculated. The experimental setup clearly demonstrated that the yield regarding fresh as well as dry matter and oil content was comparable to one square meter of open field production. Based on this, the multi-layer system and the noticeable lowered growth period result in a significantly higher area efficiency compared to the open field, leading to a potential increase of annual yields of dried leave weight and oil contents by up to 21 times. It was also shown that a white spectrum (W) showed similar influence on plant growth and yield as a spectrum consisting of blue and red (B/R). Nevertheless, the LED treatment W did show higher light use efficiencies as well as a better working conditions inside the cultivation chamber. By an integration of indoor vertical farming into existing industrial processes, new and innovative opportunities for a flexible and low-risk supply chain seem feasible and according to German food industry meet the interests of existing stakeholders.

A field experiment was conducted during rabi season of 2011-12 on heavy black soil to study the effect of integrated nutrient management on growth and yield of baby corn. The treatments comprising all possible combinations of five levels of nitrogen (chemical and vermicompost fertilizer) with and without bio-fertilizer (Azotobacter and PSB) were laid out in randomized block design with three replications. These were significantly higher with application of 100% RDN from chemical fertilizer with bio-fertilizer over 100% RDN from vermicompost. The cob and fodder yields significantly differed with different integrated nutrient management treatment. Significantly the higher growth and yield attributes yield and fodder yield were recorded with the application of 100% RDF from chemical fertilizer with bio-fertilizer. Application of 100% RDN from chemical fertilizer with biofertilizer was recorded higher net returns over 100% RDN from vermicompost (Rs. 220775/ha) and BCR (12.54).
