“…Drought stress significantly abridged the water relations (LWP, LTP, LOP and LRWC) in quinoa when compared with control treatment. Similar outcomes have been stated by Haider et al 56 in wheat and Iqbal et al 32 in cotton that DS decreased all these parameters. This decrease could be brought about by inadequate food absorption, decreased cell division, SC, and less cytokines production 57 .…”

Drought stress is a worldwide threat to the productivity of crops, especially in arid and semi-arid zones of the world. In the present study, the effect of selenium (Se) seed priming on the yield of quinoa under normal and drought conditions was investigated. A pot trial was executed to enhance the drought tolerance in quinoa by Se seed priming (0, 3, 6, and 9 mg Se L−1). The plants were exposed to water stress at three different growth stages of quinoa, viz. multiple leaf, flowering, and seed filling. It was noticed that drought significantly affected the yield components of quinoa, however, Se priming improved the drought tolerance potential and yield of quinoa by maintaining the plant water status. Se priming significantly increased main panicle length (20.29%), main panicle weight (26.43%), and thousand grain weight (15.41%) as well as the gas exchange parameters (transpiration rate (29.74%), stomatal conductance (35.29%), and photosynthetic rate (28.79%), total phenolics (29.36%), leaf chlorophyll contents (35.97%), water relations (leaf relative water contents (14.55%), osmotic potential (10.32%), water potential (38.35%), and turgor potential (31.37%), and economic yield (35.99%) under drought stress. Moreover, Se priming markedly improved grain quality parameters i.e., phosphorus, potassium, and protein contents by 21.28%, 18.92%, and 15.04%, respectively. The principal component analysis connected the various study scales and showed the ability of physio-biochemical factors to describe yield fluctuations in response to Se seed priming under drought conditions. In conclusion, a drought at the seed-filling stage has a far more deleterious impact among other critical growth stages and seed priming with Se (6 mg L−1) was found more effective in alleviating the detrimental effects of drought on the grain yield of quinoa.

“…In order to retain nutrients, the plant transports surplus nutrients to the soil through longer roots via nitrogen assimilation ( Khan et al, 2017 ), which is another potential reason for the elevated soil TN. Notably, soluble sugars in plants are indicators of energy readily available for cell metabolism ( Souza et al, 1999 ; Iqbal et al, 2021 ), and is an important indicator of C transformation and accumulation, as this provides energy and C skeletal for plant N metabolism, which affects plant growth and development ( Hu et al, 2021 ). In the aeolian sandy soil, 3% CSB significantly increased the soluble sugar content, suggesting an increase in sugar accumulation ( Hu et al, 2021 ) and promotion of nitrogen metabolism in the roots.…”

Long-term and widespread cotton production in Xinjiang, China, has resulted in significant soil degradation, thereby leading to continuous cropping obstacles; cotton stalk biochar (CSB) addition may be an effective countermeasure to this issue, with effects that are felt immediately by root systems in direct contact with the soil. In this study, we assess the effects of different CSB application rates on soil nutrient contents, root morphology, and root physiology in two soil types commonly used for cotton production in the region. Compared with CK (no CSB addition), a 1% CSB addition increased total nitrogen (TN), available phosphorus (AP), and organic matter (OM) by 13.3%, 7.2%, and 50% in grey desert soil, respectively , and 36.5%, 19.9%, and 176.4%, respectively, in aeolian sandy soil. A 3% CSB addition increased TN, AP, and OM by 38.8%, 23.8%, and 208.1%, respectively, in grey desert soil, and 36%, 13%, and 183.2%, respectively, in aeolian sandy soil. Compared with the aeolian sandy soil, a 1% CSB addition increased TN, OM, and AP by 95%, 94.8%, and 33.3%, respectively, in the grey desert soil , while in the same soil 3% CSB addition increased TN, OM, and AP by 108%, 21.1%, and 73.9%, respectively. In the grey desert soil, compared with CK, a 1% CSB application increased the root length (RL) (34%), specific root length (SRL) (27.9%), and root volume (RV) (32.6%) during the bud stage, increased glutamine synthetase (GS) (13.9%) and nitrate reductase (NR) activities (237%), decreased the RV (34%) and average root diameter (ARD) (36.2%) during the harvesting stage. A 3% CSB addition increased the RL (44%), SRL (20%), and RV (41.2%) during the bud stage and decreased the RV (29%) and ARD (27%) during the harvesting stage. In the aeolian sandy soil, 1% CSB increased the RL (38.3%), SRL (73.7%), and RV (17%), while a 3% caused a greater increase in the RL (55%), SRL (89%), RV (28%), soluble sugar content (128%), and underground biomass (33.8%). Compared with the grey desert soil, a 1% CSB addition increased the RL (48.6%), SRL (58%), and RV (18.6%) in the aeolian sandy soil, while a 3% further increased the RL (54.8%), SRL (84.2%), RV (21.9%), and soluble sugar content (233%). The mechanisms by which CSB addition improves the two soils differ: root morphology changed from coarse and short to fine and long in the grey desert soil, and from fine and long to longer in the aeolian sandy soil. Overall, a 3% CSB addition may be a promising and sustainable strategy for maintaining cotton productivity in aeolian sandy soil in the Xinjiang region.

“…Variations in precipitation from mean value and particularly the intense and erratic rainfall negatively impacts cotton productivity. The increases in temperature and shift in the rainfall cycle affect cotton growth development and threat for cotton production and quality in studied region (Saddique et al, 2021;Ahmad et al, 2021;Iqbal et al, 2021). The optimum temperature required for cotton growth and developed range between 28 °C to 37 °C but in studied region the overall average seasonal temperature is around 37 ˚C during cotton growing season that is higher than the optimum temperature ranges required by good growth and development (Filippi et al, 2021;Rahman et al, 2020).…”

Current cotton production systems are most vulnerable to climate extremes in the world but particularly in Sindh, Pakistan. There is a drier need to assess the climate vulnerability and develop climate-resilient production technologies and adaptation plan to combat the climate extremes. A study was conducted in three districts of Sindh province (Ghotki, Sukkur, and Khairpur). Both primary and secondary data of cotton growers (small, medium and large land holding) and different relevant departments of cotton was collected. Three data collection tools were used in this study. Primary data was collected directly from farmers by conducting Focus Group Discussions (FGDs) by engaging local cotton growers. Key informant interviews (KIIs) guide was used for the consultation with officials in government and other cotton related departments. Survey of cotton growers/farmers were conducted in these three districts by selecting farmers randomly. HCPL has conducted 13 FGDs with the beneficiary’s farmers (men and women). Out of the total, seven FGDs were conducted with male farmers and six FGDs were held with female farmers in three studied districts. In each FGDs 10 to 12 farmers participated actively in the discussion and data collection. In total 130 farmers consulted through FGDs in the studied region. Results showed that, the current cotton production system is vulnerable to climate change and climate resilient site-specific production technologies are required by adopting good management practices. Due to competing crops and unavailability of resources, cotton crop area has been shifted to other crops like sugarcane, so climate adaptation plan is required to reduce the cost of production. Increasing area under sugarcane crop also has negative effect on cotton crop due to high humid climatic conditions and leads to more insect pest infestation. Currently, cotton is being sown after wheat during the month of May, while sub optimum and substandard input like seed, fertilizer, and management practices being used. Farmers are also lacking in climate knowledge, and while there is no weather agro-advisory system available for farmers related to climate extremes conditions (drought, heat, and floods). Financial incentive system is also required for cotton crop just like other crops in the region. Good quality seed and input at lower rates are unavailable in this region. There is knowledge gap existed and farmer’s field school are required to develop the capacity building of the farmers to adopt climate resilient production technology. Cotton crop is sensitive to weather while climate forecast is also missing at gross root level, there is need to strength the system to deliver the information to the cotton growers to manage the cotton accordingly. There also need to strength the coordination and productive linkages with research institutes and academia that are working for the production enhancement of cotton crop. Climate resilient production technology transfer is also required to mitigate the negative effects of climate change. There is need to strengthen the marketing system of cotton for effective functioning of the key cotton value chain actors.
