“…The increase in productivity of agricultural plants under the action of biostimulants is stated by various authors. It is noted that the effect intensity depends on the type of biostimulator, its concentration and the number of applications [10][11][12][13]. The impact on crop quality indicators is also determined by various factors.…”

For the first time, data were obtained on the use of the cyanobacteria Arthrospira platensis endometabolite complex and its modifications, fortified (additionally enriched) with nutrients B, Se, and P in soybean cultivation technology, which acted not only as growth regulators, but also as adaptogens to external abiotic stress factors during the growing season of the studied crop. It was found that the use of complexes fortified with phosphorus and selenium in pre-sowing seed treatment (0.6 l/t) and foliar top dressing of vegetative soybean plants in the phase of 1-3 triple leaves provides the greatest increase in grain yield by 0.23 and 0.2 t/ha, or by 10.1 and 8.8% in the indeterminate Mezenka variety, and protein collection at the same time is 1022.5 and 1012.7 kg/ha, respectively.

“…Mamatha et al [28] studied the application of different doses of plant-based HP on soybean, pepper, and chickpea grown under thermal and water stress conditions. Foliar application of the biostimulant at a dose of 4 ml.l -1 increased the photosynthetic efficiency of treated plants.…”

Protein hydrolysates are plant biostimulants containing amino acids, oligopeptides, and peptides in their composition. When supplied to plants, protein hydrolisates (PH) have been identified to improve nitrogen metabolism, enhance the activity of antioxidant enzymes, boost plant defence response to stresses, and positively impact the quantity and quality of products. Soybean is a crucial global commodity, with nitrogen being the primary nutrient for crop development as it directly affects productivity. This study aimed to evaluate the effect of a HP-based biostimulant on the N metabolism in nodulated soybean plants and their productivity. A greenhouse experiment was conducted to test two modes of application of the 0.20% HP-based biostimulant. Soybean plants, growing in pots, were treated with HP 0.20% either via seed treatment or foliar application (at growth stages V3 and V5). Activities of enzymes and compounds related to N metabolism, gene expression, and productivity components were analysed. It was observed that the mode of application did not significantly influence the results. The application of HP increased the concentration of nitrate, amino acids, and ureides in soybean leaves. It also positively altered the expression of genes such as nitrate reductase, urease, and asparagine. Additionally, it enhanced productivity, resulting in plants with a greater number and weight of pods and grains. Therefore, it is possible to consider HP as a stimulator for increasing soybean productivity, even under non-stressing conditions.

Chickpea is a cool season, photothermal-sensitive crop, that is adversely affected by high temperatures (>35°C) and whose flowering is promoted by long-day conditions (>12 h). This prevents horizontal crop spread under a variety of agro-climatic conditions and the development of insensitive genotypes that perform well in all seasons. Therefore, a study was conducted to identify genotypes that are mature early, insensitive to photoperiod, high temperature and tolerant to drought stress. A set of 74 genotypes was evaluated under rainfed conditions in Kharif 2021 (off-season) to select eight promising early-maturing genotypes with high-yielding capacity. Then further investigations were conducted in five different seasons Late Kharif 2021, rabi 2021, summer 2022, early Kharif 2022 and Kharif 2022 to identify the genotypes with photothermo-insensitivity among the selected eight genotypes. With the exception of rabi 2021, each of these seasons were distinct from the chickpea's typical growing season. Among these eight, the stable genotypes which are performed better in all the seasons, especially in summer were considered, such as IPC 06-11, MNK-1, JG-14 and ICE 15654-A as a photothermo-insensitive, were able to flower and set pods with higher seed yield and, resulting in early maturity in a temperature range of 41.4/9.3°C with photoperiods of 13.1/10.9 h to reach in all seasons throughout the year. The heritability was more than 60%. Hence, these genotypes can be used as donor aids in the development of early maturing, drought stress tolerant and photothermo-insensitive chickpea.
