“…Meantime, cotton bed planting showed the highest cotton yield (1946 kg.ha −1 ), followed by ridge sowing without mulch (1886 kg.ha −1 ) and bed planting with mulch (1643 kg.ha −1 ). Although the cotton yield of the bed planting method is highest in the current study, still less than previously reported (Mudassir et al 2021 ), the primary reason could be late sowing. However, cotton yield in bed planting is obvious to choose the best method among others.…”

Irrigated agriculture is a foremost consumer of water resources to fulfill the demand for food and fiber with an increasing population under climate changes; cotton is no exception. Depleting groundwater recharge and water productivity is critical for the sustainable cotton crop yield peculiarly in the semiarid region. This study investigated the water productivity and cotton yield under six different treatments: three sowing methods, i.e., flat, ridge, and bed planting with and without plastic mulch. Cotton bed planting without mulch showed maximum water productivity (0.24 kg.m−3) and the highest cotton yield (1946 kg.ha−1). Plastic mulching may reduce water productivity and cotton yield. HYDRUS-1D unsaturated flow model was used to access the groundwater recharge for 150 days under six treatments after model performance evaluation. Maximum cumulative recharge was observed 71 cm for the flat sowing method without plastic mulch. CanESM2 was used to predict climate scenarios for RCP 2.6, 4.5, and 8.5 for the 2050s and 2080s by statistical downscale modeling (SDSM) using historical data from 1975 to 2005 to access future groundwater recharge flux. Average cumulative recharge flux declined 36.53% in 2050 and 22.91% in 2080 compared to 2017 without plastic mulch. Multivariate regression analysis revealed that a maximum 23.78% reduction in groundwater recharge could influence future climate change. Further study may require to understand the remaining influencing factor of depleting groundwater recharge. Findings highlight the significance of climate change and the cotton sowing method while accessing future groundwater resources in irrigated agriculture.

“…In the present study, water scarcity hinders cotton growth, resulting in decreased yields, fewer bolls per plant, lighter seed cotton bolls, and lower ginning outturn percentage. Seed cotton yield is a crucial indicator of crop productivity and is often used to compare different varieties or growing conditions (Mudassir et al, 2021). Drought stress causes stunted growth, reduced leaf area, and smaller stems in plants, leading to reduced boll numbers and seeds produced (Nazim et al, 2021).…”

Asparagine (Asn) and nitric oxide (NO) can enhance plant tolerance to abiotic stress, but their interaction is not well understood. Cotton is a vital resource for the textile industry, but its yield is reduced by drought stress, which could threaten its global supply in a warming and stressful world. Improving cotton's drought tolerance is crucial for supporting the textile industry. Two simultaneous field experiments were conducted to study the effect of Asn and sodium nitroprusside (SNP), a NO donor, on cotton's drought tolerance. Two irrigation treatments were applied: control (C: 100% A pan) and drought stress (50% A pan). The plants were also sprayed with two plant stimulants before imposing drought stress: Mock control, 20 mM Asn, and 0.2 mM SNP, either alone or together. Drought stress impaired plant growth, photosynthesis, yield, nitrogen metabolism, and antioxidant defense, while increasing oxidative stress and free amino acid levels. However, Asn and SNP treatments alleviated these negative effects and improved antioxidant enzyme activity, plant growth, yield, and nitrogen content. The Asn + SNP treatment also increased irrigation water productivity under water‐limited conditions, suggesting its potential for enhancing water use efficiency in cotton production. The combined treatment was more effective than the single treatments, indicating a synergistic effect of Asn and SNP in enhancing drought tolerance in cotton. These results imply that Asn and SNP could be useful tools for sustaining cotton production under drought conditions by boosting nitrogen metabolism and antioxidant defense, thereby contributing to the global supply of cotton and supporting the textile industry.

“…Some studies have demonstrated good predictive ability even with only three variables [67]. For this study, we considered the following variables because of their importance to the cotton plant [2,15,[68][69][70][71]: annual available soil water (mm year −1 , AASW), Flowering Growing Degree Days (FGDD), absolute minimum temperature ( • C, Tminabs), and altitude (amsl, ALT).…”

“…Flowering Growing Degree Days: the variable Growing Degree Days (GDD), also known as Heat Units (HUs) or thermal time, reflects the relationship between growth rate and temperature and refers to the specific amount of heat units that plants require to develop from one stage of development to another [15,[77][78][79][80]. In the present study, we considered Flowering Growing Degree Days (FGDD), which refers to the necessary GDD to cover the flowering phase, the prime physiological stage of the cotton plant that determines the final productivity [2,71]. It is calculated as follows:…”

Loss and Gain in Potential Distribution of Threatened Wild Cotton Gossypium thurberi in Mexico under Future Climate

et al. 2022

Gossypium thurberi, a threatened wild cotton species native to northern Mexico and southwestern USA, is globally important because its agronomic traits can be introgressed into cultivated species to improve fiber quality and resistance to biotic and abiotic stressors. However, studies on the current and future potential distribution of the species are scarce. The objectives of this study were (1) to develop a distribution model of G thurberi using a Geographic Information System platform, (2) determine environmental factors that influence the current distribution of the species in Mexico, and (3) estimate the potential distribution of the species under current and future climates. We analyzed the following variables: Annual Available Soil Water (mm year−1, AASW), Flowering Growing Degree Days (FGDD), absolute minimum temperature (°C, Tminabs), and altitude (amsl, ALT). Results showed that the current potential distribution of G. thurberi in northern Mexico, estimated at 112,727 square kilometers, is projected to be drastically reduced by 77 and 86%, considering a possible increase in temperature of 1.5 °C and 2 °C in near-future (2021–2040) and mid-future (2041–2060) climates, respectively, and a 100 mm reduction in average annual precipitation under both climates. The greatest reduction will be in areas in Sonora (Mexico) adjoining Arizona (USA), where the largest populations of the species are currently reported. AASW, FGDD, and ALT jointly influence the distribution of G. thurberi, with AASW as the dominant factor under future climate change. The areas that may continue to harbor populations of G. thurberi under future climate will present AASW of 0.2–55.6 mm year−1, FGDD of 242–547, and ALT between 550 and 1561 amsl. The projected future potential distribution in the country includes new suitable areas, including one in the Trans-Mexican Volcanic Belt, that may serve as refuge areas. The findings can contribute to the design of more precise collection efforts and conservation strategies to prevent species extinction.
