“…Additionally, overgrazing over extended periods alters the composition of dominant species [13,14], the distribution of forage and poisonous species on pastures [15,16], and negatively impacts vegetation productivity [17], greenhouse gas balance, and biodiversity [18][19][20]. In most countries, including Kazakhstan, due to climatic conditions and traditional systems of free (excessive) grazing, strong destruction of vegetation is observed [21][22][23].…”

Monitoring pasture vegetation indicators is critical as decreased productivity could jeopardize the stability of pasture lands. This study aimed to evaluate the status of vegetation cover across pastures utilized in diverse manners within the semi-desert zone of Western Kazakhstan. Specifically, the impacts of rotational, seasonal, and intensive grazing on the functionality, diversity, and productive potential of pasture vegetation were investigated. Systematic vegetation observations, including species diversity examination, projective coverage estimation, height measurements, and yield determination, were conducted in transects established across pastures with varying grazing methods at the Miras farm in Western Kazakhstan. The findings reveal that unregulated intensive grazing significantly altered vegetation indicators, suggesting potential degradation processes. Intensive grazing proved particularly detrimental, resulting in decreased species richness, projective coverage, height, and a lower productive vegetative mass. In contrast, rotational and seasonal grazing methods appeared more effective in Western Kazakhstan. Pastures where regulated grazing was practiced exhibited higher species richness and biometric and production indicators compared to those with unsystematic grazing. Understanding the alterations in biometric and productive vegetation indicators relative to grazing practices is crucial for quality assessment of pastures and determining appropriate pasture management. The absence of adequate and efficient grazing could trigger irreversible deterioration in pasture vegetation conditions. Therefore, to safeguard the biological resources and biodiversity of the region's pastures, it is strongly advocated to employ regulated grazing and entirely eliminate excessive intensive grazing. This approach will help maintain a healthy balance in the pasture ecosystem and promote sustainable farming practices.

The application of superabsorbents to soils and seed coatings is a pre-sowing seed treatment method that is commonly used to improve early vigor and establish stability and uniformity under water deficit conditions. To evaluate the interaction of seed coating and superabsorbent on Calotropisprocera L. (milkweed) under water deficit conditions, a greenhouse experiment was conducted. The experiment was conducted with four coating material levels (non-coated seeds and seeds coated with peat moss, vermicompost, and canola residue), four growth medium levels (soil, sand + soil, soil + 2 g superabsorbent, and soil + 4 g superabsorbent), and three field capacity regimes (25, 50%, and 100%) in a completely randomized design factorial arrangement with four replications. Reducing the field capacity from 100 to 25% led to decreased growth (shoot and root dry weights and leaf area) and chlorophyll content. The activities of SOD, CAT, APX antioxidant enzymes, and proline increased under drought stress. The use of superabsorbent polymers in growth media enhanced growth indices and chlorophyll content and decreased the activity of antioxidant enzymes and proline under water deficit conditions. The highest chlorophyll and growth indices were observed when 4 g of superabsorbent was added to the growth medium under drought stress. The application of 4 g of superabsorbent to the growth medium reduced the activity of antioxidant enzymes and proline. The use of seed coatings improved the growth indices, antioxidant enzyme activity, and chlorophyll content under drought stress. The most adaptive morphological and physiological responses to water stress were observed in the vermicompost-coated seeds. The vermicompost coating containing a superabsorbent polymer (4 g/kg soil) proved to be the best for establishing milkweed under mild (50% FC) and severe water deficits (25% FC).
