“…Similarly, it can also solve the problem of burning of crop residues, which resulted in air pollution in the region. The results confirmed that conservation tillage has great potential to manage resources on a sustainable basis under a changing climate [82][83][84][85][86][87][88][89][90].…”

In South Asia, soil health degradation is affecting the sustainability of the rice-wheat cropping system (RWCS). Indeed, for the sustainability of the soil quality, new adaptive technologies, i.e., conservation tillage and straw management resource conservation, are promising options. This investigation was focused on the interaction of tillage and straw management practices and their effects on Aridisols, Yermosols soil quality, and nutrients dynamics with different soil profiles within RWCS. The long-term field experiment was started in 2014 with the scenarios (i) conventional tillage (SC1), (ii) residue incorporation (SC2), (iii) straw management practices (SC3 and SC4) and conservation tillage (SC5). Conservation tillage practice (SC5) showed significant impact on properties of soil and availability of nutrients in comparison with that of conventional farmers practice (SC1) at the studied soil depths. The SC5 showed significant results of gravitational water contents (25.34%), moderate pH (7.4), soil organic-matter (7.6 g kg−1), total nitrogen (0.38 g kg−1), available phosphate (7.4 mg kg−1), available potassium (208 mg kg−1) compared to SC1 treatment at 0 to 15 cm soil depth. Whereas, DTPA-extractable-Cu, Mn, and Zn concentration were significantly higher, i.e., 1.12 mg kg−1, 2.14 mg kg−1, and 4.35 mg kg−1, respectively under SC5 than conventional farmer’s practices, while DTPA (diethylene triamine pentaacetic acid) extractable Fe (6.15 mg kg−1) was more in straw management practices (SC4) than conventional and conservation tillage. Therefore, conservation tillage (SC5) can surge the sustainability of the region by improving soil assets and nutrients accessibility and has the potential to minimize inorganic fertilizers input in the long run.

“…They further suggested that the reduction in photosynthesis was only related to the closure of stomata in trees in the canopy and undergrowth [39]. It was also found in wheat that drought decreased stomatal conductance, increased stomatal resistance, and decreased photosynthetic rate and transpiration rate [40]. However, with the increase of water deficit, non-stomatal factors began to play an important role.…”

With the global climate anomalies and the destruction of ecological balance, the water shortage has become a serious ecological problem facing all mankind, and drought has become a key factor restricting the development of agricultural production. Therefore, it is essential to study the drought tolerance of crops. Based on previous studies, we reviewed the effects of drought stress on plant morphology and physiology, including the changes of external morphology and internal structure of root, stem, and leaf, the effects of drought stress on osmotic regulation substances, drought-induced proteins, and active oxygen metabolism of plants. In this paper, the main drought stress signals and signal transduction pathways in plants are described, and the functional genes and regulatory genes related to drought stress are listed, respectively. We summarize the above aspects to provide valuable background knowledge and theoretical basis for future agriculture, forestry breeding, and cultivation.

“…Tropical and subtropical region of the world will be the greatest exaggerated areas for increasing temperature (Gourdji et al., 2013). The prime reason of this, growing global mean temperature, increases in atmospheric CO 2 level that rises the frequency, intensity and period of heat waves (Ahmed, 2017; Ahmed & Stockle, 2016). Predictable grain yield nearly suffers from 6% to 10% per 1°C increase in temperature at the grain‐filling stage (Asseng et al., 2015; Lobell et al., 2008; Mondal et al., 2013).…”

High temperature affects wheat yield severely. This study aimed to explore the variation and recognition of heat responsive traits, to enhance wheat productivity in high temperature stress condition. The recombinant inbred lines were developed by crossing of released wheat variety MACS2496 (heat sensitive) and WH730 (heat tolerant). The experiments were conducted into 2 years at three locations of two planting conditions (heat and terminal heat stress). Combined analysis of variance shows significant variations among all the studied traits at individual location, year and planting conditions. The phenological and yield component traits were highly influenced by environment under terminal heat stress condition. Days to heading and thousand kernel weight coupled with high heritability and high genetic advance per cent of mean in heat and terminal heat stress environments. In heat and terminal heat stress planting conditions, tiller number per plant, kernels per spike, kernel weight per spike and thousand kernel weight confirm positive relationship with grain yield per plant by correlation and principal component analysis. Path and multiple regression analysis accomplish that tiller number per plant, kernel weight per spike, kernel per spike and thousand kernel weight were identified as the key contributor towards grain yield per plant in heat and terminal heat stress environment. Thus, all‐inclusive approaches demonstrated that the promising traits deliver a framework to develop heat tolerant cultivars in future.
