Predicting germination timing and the responses of various genotypes to temperature and drought stress is essential for identifying genotypes that are tolerant to adverse environmental conditions.Hence, the present study aimed to determine the cardinal germination temperatures of sorghum genotypes and examine the impact of priming on their hydrotime model coefficientsThe first experiment grew the sorghum varieties Pegah, Speedfeed, and Pejpal at nine temperatures (5-45°C).revealed that base temperatures were very similar for all genotypes, and optimum temperatures ranged from 25.46 to 31.38°C.The ceiling temperature was estimated at 42°C for all varieties.Factors of the second experiment included in the hydrotime model were six drought levels between 0 and -2 MPa, and priming at four levels (control, hydropriming, and nanopriming with potassium nanosilicate (PNS) and nanozinc oxide (nZnO) at 250 mg/l concentrations).of the hydrotime model showed that coefficients were influenced by priming, such that priming treatments decreased the hydrotime coefficient (θH) and made the base potential more neg.The Pejpal genotype under unprimed control conditions was the most drought tolerant, but Speedfeed was the most drought sensitive.In addition, PNS treatment was the most effective at increasing the germination of sorghum genotypes, as it decreased the base potential by at least -0.3 MPa.The outputs of the nonlinear regression and hydrotime models can predict germination speed under various environmental conditions.Moreover, hydrotime anal. helps identify resilient genotypes and effective seed treatments to mitigate the adverse effects of challenging environments.

The use of biochar in crop production has garnered attention for its potential to improve soil fertility, water-holding capacity, and carbon sequestration.However, in arid and semi-arid regions where yield is constrained by water scarcity and fertilizer cost, the application of biochar is an important strategy to increase yield.This study evaluates the effects of different biochar levels (0%, 1.5%, and 3%) and watering regimes (50% and 100% of field capacity) on two rapeseed varieties (Sarigol and RGS) in a greenhouse experimentThe results demonstrated that biochar application could alleviate the neg. effects of water deficit on zinc (Zn) (21.48%) content for both rapeseed varieties in comparison with control.Also, 3% biochar increased Copper (Cu) (10%) and Potassium (K) content (64.3%) in varieties compared to the control.The application of biochar in crop fields of southern Iran, characterized by poor soil quality and water scarcity, could represent an available and sustainable strategy for crop production under future climate change conditions.

The purpose of this study was to (a) examine personal healthcare practices of rural medical providers by issue type (e.g., physical health, social health, or mental health), (b) identify perceived consequences of taking time off and (c) determine whether greater delay in self-care was associated with perceived stress and burnout.

Electronic surveys were sent to 805 medical providers (response rate = 17.8%, n = 143).

The setting was a rural teaching hospital and affiliated community clinics.

Participants included 143 rural medical providers.

The survey included demographic information, perceived personal health risk, and questions about delaying health care, and perceived consequences of receiving health care.

Medical providers delayed mental health care needs significantly more than physical health needs, t131 = 5.13, P < .01, d = .38. Respondents believed that there would be significantly more retaliation against them for taking time off for psychosocial issues, t124 = −3.80, P < .001, d = .25. There was a significant negative association between burnout and physical health self-care (r = −.24, P < .01), psychosocial self-care (r = −.20, P = .01), and mental health self-care (r = −.23, P < .01).

Our study identified commonly reported consequences related to taking off work for care seeking behavior. Understanding perceived consequences can help guide health care organizations in dismantling these barriers. This study is limited by the generalizability of its sample.
