    One of the types of sorghum, the most drought-resistant crop in the world, sugar sorghum (Sorghum Saccharum) is characterized by the fact that, unlike grain and broom sorghum, its stem juice contains more than 10-20% sugars. Because it can be cultivated in the arid southern regions, where it is either unprofitable or impossible to grow sugar beets, the interest in sugar sorghum is undeniable. The study aimed to identify highyielding varieties of sugar sorghum of domestic and foreign selection with a high content of soluble carbohydrates, characterized by resistance to adverse environmental conditions. Introduction of sugar sorghum in risky agriculture zones of the Republic of Kazakhstan for use as food, feed industries, and alternative renewable energy. The article reveals high-yielding varieties of sugar sorghum of domestic and foreign selection with a high content of soluble carbohydrates, characterized by resistance to adverse environmental conditions and their introduction in the zones of risky farming of the Republic of Kazakhstan.

    This study investigates the potential of biochar derived from various biomass sources: apricot kernel (AK), pine sawdust (PS), rice husk (RH), wheat straw (WS), and reed stem (RS) to enhance the yield, nutritional quality, and environmental sustainability of parsley crops. Comprehensive characterization through SEM, EDAX, nitrogen adsorption–desorption isotherms, and FTIR analyses identified AK biochar as the most suitable for further enrichment due to its superior specific surface area (512.3 m2/g) and iodine number (51.23 mg/g). EDAX analysis revealed that AK biochar exhibited the highest carbon content (92.1%), while RH biochar contained the highest silicon content (46%), indicating different potential applications. FTIR analysis identified key functional groups, such as carbonyl (1740 cm⁻1) and hydroxyl (3430 cm⁻1) groups, which contribute to the biochar’s reactivity and potential effectiveness in various applications. The effects of selenium (Na2SeO4), iodine (KI), their combination (Na2SeO4 + KI), and BISF (biochar‐enriched iodine and selenium fertilizer) on parsley growth, antioxidant properties, and nutrient accumulation were evaluated. The results demonstrated that joint applications of iodide and selenate led to a 3.1‐fold increase in iodine content (up to 16.8 mg/kg d.w.) and a 1.2‐fold increase in selenium accumulation (up to 2482.1 μg/kg d.w.) in parsley compared to separate treatments. Additionally, BISF treatment significantly improved key biometric parameters, with leaf weight increasing by 1.6 times (up to 326.5 g) compared to the control, and antioxidant content—ascorbic acid, polyphenols, and antioxidant activity—showing increases of 1.56, 1.27, and 1.50 times, respectively. This study underscores the effectiveness of selenium‐ and iodine‐enriched biochar in enhancing parsley crop yield and nutritional quality while also demonstrating the multifunctional role of biochar in environmental remediation.

    This study explores the possibility of making cardboard and molded egg carton packaging from corn residues and common reed as alternatives to wood-based pulp. Six formulations were made: corn husks (CHs), corn leaves (CLs), corn leaves (35%) plus corn husks (30%) and a corn blend (15%) of wollastonite (CaSiO3) (CH + CL + W), a corn blend (CH + CL: husks 60%, leaves 40%), mixed corn waste (MCW) and shredded common reed (SR). Optical microscopy was used to evaluate the fiber morphology, including the calculation of the flexibility coefficient, the cell wall rigidity and the Runkel ratio, for raw materials and fiber after alkaline hydrolysis and casting of egg cartons in silicone molds. The grammage, burst strength and index, folding endurance, thickness and moisture content were measured in the cardboard samples, while warping, compressive deformation, moisture and ink absorption were measured in the egg cartons. The flexibility coefficient of the common reed fibers (64.5%) was better than that of the corn fibers (23.6%), and so was the Runkel ratio (0.86 vs. 1.2). In the case of cardboard formulations, the maximum burst strength (462.4 kPa) and the maximum burst index (3.0 kPa·g/m2) values were obtained with the MCW formulation, and the highest folding endurance (42 and 38 double folds) was obtained with the CH and SR formulations, respectively. The addition of wollastonite improved folding endurance to 28 double folds and reduced moisture content to 4.1%, whereas the moisture content was reduced but burst strength decreased to 250.5 kPa. Egg cartons made from corn were found to satisfy all the requirements tested for good packaging, while the reed-based cartons were found to have inadequate ink absorbency time (20 min), making them less printable. Overall, mixed corn residues seem to be the most promising raw materials for sustainable packaging, and wollastonite can be used to adjust the flexibility–strength balance.
