“…When soil or water contains high concentrations of salts, particularly sodium chloride, it can impede plant development and result in numerous negative consequences [ 6 – 9 ]. The detrimental effects of salinity stress on crops encompass reduced water uptake due to osmotic imbalance, ion toxicity that disrupts essential nutrient balance [ 4 , 10 ], impaired nutrient uptake, stunted growth, increased oxidative stress, altered metabolism, and diminished crop yield and quality [ 11 ]. Excess salts hinder water absorption by plants, leading to dehydration and water stress [ 12 , 13 ].…”

Salinity stress is one of the major hurdles in agriculture which adversely affects crop production. It can cause osmotic imbalance, ion toxicity that disrupts essential nutrient balance, impaired nutrient uptake, stunted growth, increased oxidative stress, altered metabolism, and diminished crop yield and quality. However, foliar application of osmoprotectant is becoming popular to resolve this issue in crops. These osmoprotectants regulate the cellular osmotic balance and protect plants from the detrimental effects of high salt concentrations. Furthermore, the role of arbuscular mycorrhizae (AMF) is also established in this regard. These AMF effectively reduce the salinity negative effects by improving the essential nutrient balance via the promotion of root growth. That’s why keeping in mind the effectiveness of osmoprotectants current study was conducted on cotton. Total of six levels of γ-Aminobutyric acid (GABA = 0 mM, 0. 5 mM, and 1 mM) and ectoine (ECT = 0 mM, 0.25 mM, and 0.5 mM) were applied as treatments in 3 replications. Results showed that 0.5 mM γ-Aminobutyric acid and ectoine performed significantly best for the improvement in cotton growth attributes. It also caused significant enhancement in K and Ca contents of the leaf, stem, bur, and seeds compared to the control. Furthermore, 0.5 mM γ-Aminobutyric acid and ectoine also caused a significant decline in Cl and Na contents of leaf, stem, bur, and seeds of cotton compared to control under salinity stress. A significant enhancement in chlorophyll contents, gas exchange attributes, and decline in electrolyte leakage validated the effectiveness of 0.5 mM γ-Aminobutyric acid and ectoine over control. In conclusion, 0.5 mM γ-Aminobutyric acid and ectoine have the potential to mitigate the salinity stress in cotton.

“…Nutrients available in sufficient quantities will encourage the process of photosynthesis to be more active which results in the formation of higher proteins to support the high growth of plants. In line with Ghaffoor et al [18] that manure exerts a good influence on the physical and chemical properties of the soil through the improvement of soil structure, sources of nutrients for plants [19] and increases soil microorganisms [20].…”

Utilization of biodiversity in the form of medicinal plants is an alternative to maintain health. Dayak onions as efficacious medicinal plants, have the potential to be developed. The optimal benefits of Dayak onions can be obtained if the raw materials used are of high quality. Environmental factors greatly affect the quality and quantity of tubers, including cultivation techniques and soil types. This research aims to study various cultivation techniques and soil types to improve the agronomical characteristics and flavonoid content of Dayak Onion. The study used a factorial randomized block design,3 repetitions. Factor I was the type of soil (T1=peat soil; T2=sandy soil). Factor II was the type of cultivation technique B0=without fertilization; B1=organic fertilization (chicken manure 20 t.ha -1 ); B2=inorganic fertilization (200 kg.ha -1 urea,150 kg.ha -1 SP-36,200 kg.ha -1 KCl); B3=combination of organic+inorganic fertilization. The results showed that the interaction treatment of various cultivation techniques and soil types had a significant effect on plant height, number of leaves, number of saplings. The combination of organic+inorganic fertilizers (chicken manure 20 t.ha -1 and 200 kg.ha -1 urea+150 kg.ha -1 SP-36+200 kg.ha -1 KCl) planted on peat soil types gives the best results on tuber wet weight 48.27 g/clump, dry tubers 16.73 g (12 wap) The average content of flavonoids planted on peat soil was higher 64.75 compared to sandy soil 52.33.

“…To date, studies related to salt tolerance mechanisms have indicated that the reduction of plant growth and yield under salinity is generally attributed to combined effects of lower osmotic potential of soil solution, disturbances in nutrients uptake and toxic effects of harmful ions [20]. Accumulation of toxic salts mainly sodium and chloride ions are the main causative factors for the physiological damage under salinity, disturbs cellular metabolic processes and all morphophysiological traits.…”

“…These physiological traits indicate genetic variability for salt tolerance. Thus, there is a need to explore physiological significance of particular traits in plant adaptation and productivity under saline conditions [20]. The threshold (maximum soil salinity level without yield loss) of rice is EC 3 dS/m, beyond this level yield starts decreasing and is drastically reduced at EC 10 dS/m.…”

World is facing the foremost challenges of abiotic stresses in agriculture among which salinity is one of the disastrous factors towards rice production. Rice is a salinity sensitive crop; however, the level of salinity varies in different cultivars. Hence, for this scenario salt tolerant genotypes are required to enhance the productivity of rice, to overcome the demand of world's population. The present research was carried out to evaluate the performance of fifteen F1 hybrids and their parents of (Oryza sativa L.) at different intensities of salt stress under hydroponic condition (greenhouse) a t Plant Physiology Division, Nuclear Institute of Agriculture (NIA), Tandojam during Kharif season of 2021 by using Factorial Designin (RCBD). Based on the performance of, by using three different treatments of salt stress such as (T1 = control 0.0 dS m -1 , T2 = 6 dS m -1 and T3 = 8 dS m -1 NaCl). During experiment, morphological attributes under observations were, root length(cm), shoot length(cm), root fresh weight(g), shoot fresh weight(g) and root, and shoot dry weight(g). Fifteen F1 hybrids and six parents were assessed for various morphological traits under various salt treatments at hydroponic condition and showed significant variation for genotypes, treatments and interaction at P<0.01 probability under both saline stress T2 = 6 dS m -1 and T3 = 8 dS m -1 NaCl. The superior hybrids as (KSK-133xHHZ-10-SAL-DT1 DT1) (90.38cm), (RST-177x Kharagnjia), (HHZ-10 SALxGML-498), (HHZ-10-SAL DT1 DT1x Kharaganjia) and (FL-478xKharangania) observed short stature height, more number of grains panicle -1 and seed yield plant -1 than their parents under both T2 = 6 dS m -1 and T3 = 8 dS m -1 conditions of NaCl which indicate high tolerability of genotypes.
