    Achieving food security while protecting the environment in the context of future global climate changes is a great challenge to the sustainability of modern agricultural systems. Food production is likely to maintain priority over environmental protection. In modern agriculture, input management is very crucial for sustaining future food security and environmental protection which might be achieved by the integration of land, pest, disease, nutrient, and other resource management practices. This chapter focuses on the potential of next-generation input management techniques for safer food production and environmental protection. The possible impacts of next-generation input management techniques for safer and nutritious food production without environmental degradation as along with other vital dimensions of food security have been discussed. Additionally, next-generation input assessment studies, possible integration of different techniques, and approaches for food and environment security have been objectively described. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2021.

    Environmental and Economic Benefits of Sustainable Sugarcane Initiative and Production Constraints in Pakistan: A Review
    (Springer International Publishing, 2023) Raza, Hafiz Ali; Hameed, Muhammad Usman; Islam, Mohammad Sohidul; Lone, Naveed Ahmad; Raza, Muhammad Ammar; Sabagh, Ayman E. L.
    Sugarcane crop has a vital role to play in the economy of developing countries. The crop requires a high amount of water during its development. Therefore, it becomes necessary to adopt innovative, ecofriendly, and water-efficient methods for its cultivation. In this chapter, sugarcane production constraints have been discussed to promote sustainable sugarcane production with special reference to Sustainable Sugarcane Initiative (SSI) techniques. The constraints include high input costs, poor production practices, water scarcity, lack of implementation of modern technologies, less incentives, climate change, and delay in payment to the farmers. Sugarcane production can significantly be increased by using SSI with less input costs, efficient water utilization, reduction of weed losses, and controlling the infestation of pests and diseases. There is a need to take proper steps for increasing the production and profitability of sugarcane by timely irrigation, cost-effective inputs, better-quality seeds, and preventive measures against post-harvest losses. The capacity building of sugarcane farmers is also recommended. © The Editor(s) (ifapplicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG 2022.

    (Springer Heidelberg, 2023) Ahmed, Sarfraz; Iqbal, Muhammad; Ahmad, Zahoor; Iqbal, Muhammad Aamir; Artyszak, Arkadiusz; Sabagh, Ayman E. L.; Alharby, Hesham F.
    Heavy metals (HMs) especially cadmium (Cd) absorbed by the roots of crop plants like maize have emerged as one of the most serious threats by causing stunted plant growth along with disturbing the photosynthetic machinery and nutrient homeostasis process. A trial was conducted for inducing Cd stress tolerance in maize by exogenous application of silicon nanoparticles (SiNPs) using five doses of SiNPs (0, 100, 200, 300, and 400 ppm) and three levels of Cd (0, 15, and 30 ppm) for maize hybrid (SF-9515). The response variables included morphological traits and biochemical parameters of maize. The results indicated that Cd level of 30 ppm remained the most drastic for maize plants by recording the minimum traits such as shoot length (39.35 cm), shoot fresh weight (9.52 g) and shoot dry weight (3.20 g), leaf pigments such as chlorophyll a (0.55 mg/g FW), chlorophyll b (0.27 mg/g FW), total contents (0.84 mg/g FW), and carotenoid contents (0.19 mu g/g FW). Additionally, the same Cd level disrupted biochemical traits such as TSP (4.85 mg/g FW), TP (252.94 nmol/g FW), TSAA (18.92 mu mol g(-1) FW), TSS (0.85 mg/g FW), and antioxidant activities such as POD (99.39 min(-1) g(-1) FW), CAT (81.58 min(-1) g(-1) FW), APX (2.04 min(-1) g(-1) FW), and SOD (172.79 min(-1) g(-1) FW). However, a higher level of Cd resulted in greater root length (87.63 cm), root fresh weight (16.43 g), and root dry weight (6.14 g) along with higher Cd concentration in the root (2.52 mu g/g(-1)) and shoot (0.48 mu g/g(-1)). The silicon nanoparticles (Si NPs) treatment significantly increased all measured attributes of maize. The highest value was noted of all the parameters such as chlorophyll a (0.91 mg/g FW), chlorophyll b (0.57 mg/g FW), total chlorophyll contents (1.48 mg/g FW), total carotenoid contents (0.40 mu g/g FW), TSP (6.12 mg/g FW), TP (384.56 nmol/g FW), TSAA (24.64 mu mol g(-1) FW), TSS (1.87 mg/g FW), POD (166.10 min(-1) g(-1) FW), CAT (149.54 min(-1) g(-1) FW), APX (3.49 min(-1) g(-1) FW), and SOD (225.57 min(-1) g(-1) FW). Based on recorded findings, it might be inferred that higher levels of Cd tend to drastically reduce morpho-physiological traits of maize and foliage-applied silver nanoparticles hold the potential to ameliorate the adverse effect of Cd stress on maize.

    Normalized Difference Vegetation Index and Chlorophyll Content for Precision Nitrogen Management in Durum Wheat Cultivars under Semi-Arid Conditions
    (Mdpi, 2021) Kizilgeci, Ferhat; Yildirim, Mehmet; Islam, Mohammad Sohidul; Ratnasekera, Disna; Iqbal, Muhammad Aamir; Sabagh, Ayman E. L.
    To impart sustainability to modern intensive farming systems, environmental pollution caused by nitrogenous fertilizers in needs to be reduced by optimizing their doses. To estimate the grain yield and nutrtional quallity of wheat, the normalized difference vegetation index (NDVI) and chlorophyll content (SPAD) are potential screening tools to identify the N deficiency and screen out the promising cultivars. The two-year field study was comprised with five levels of nitrogen (N) (control, 50, 100, 150 and 200 kg N ha(-1)) and two durum wheat genotypes (Sena and Svevo). The experimental design was split-plot, in which N levels were placed in the main plots, while wheat genotypes were arranged in sub-plots. To predict the yield and quality traits, the NDVI and SPAD values recorded at heading, anthesis and milky growth stages were taken as response variables. The results revealed that N fertilization significantly influenced the SPAD and NDVI attributed traits of durum wheat, except NDVI at milky stage (NDVI-M) during the first year. The maximum value of NDVI was recorded by 150 kg N ha(-1), while control treatment gave the minimum value. The grain yield was increased with the increasing dose of the N up to 100 kg N ha(-1) (4121 kg ha(-1)), and thereafter, it was declined with further increased of N levels. However, the variation between the genotypes was not significant, except NDVI and SPAD values at the milky stage. The genotype Svevo had the highest NDVI values at all growth stages, while the genotype Sena recorded the maximum SPAD values during both years. Similarly, the N levels significantly influenced the quality traits (protein, wet gluten, starch test weight and Zeleny sedimentation) of both genotypes. The highly significant relationship of SPAD and NDVI with the grain yield and yield attributes showed their reliability as indicators for determining the N deficiency and selection of superior wheat genotypes for ensuring food security under climate change scenario.

    Prospective role of plant growth regulators for tolerance to abiotic stresses
    (Springer International Publishing, 2021) Sabagh, Ayman E. L.; Hossain, Akbar; Islam, Mohammad Sohidul; Iqbal, Muhammad Aamir; Amanet, Khizer; Mubeen, Muhammad; Nasim, Wajid
    Abiotic stresses (heat, drought, salinity, and heavy metals) are projected to drastically reduce crop yields leading to seriously jeopardizing the food security of increasing population across the globe. Plant growth regulators (PGRs) are natural or synthetic substances that regulate the growth and differentiation of plant cells, tissues, and organs. Although the roles of PGRs in improving plant growth and development are well documented, their role in plant stress tolerance is continued to be explored. Among the PGRs, auxins, gibberellins, cytokinins, abscisic acid, jasmonic acid, ethylene, salicylic acid, nitric oxide, brassinosteroids, strigolactones, and polyamines have got the attention of the researchers as a sustainable source to improve abiotic stress tolerance under changing climate. Recently, numerous advancements have led to identify PGRs effects and to understand how plant growth responses are regulated by PGRs under abiotic stress. Different strategies are being employed to improve plant growth under abiotic conditions; the application of PGRs in crops offers good outcomes. However, it needs more researches and discussions on the said subject. Therefore, this chapter is focused on the stress management and role of PGRs in conferring abiotic stress tolerance under changing climate as it will play a key role to policymakers' food, nutritional, environmental, and economic security for the present and future generation demand. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2021.

    Strigolactones: A novel carotenoid-derived phytohormone - biosynthesis, transporters, signalling, and mechanisms in abiotic stress
    (Springer International Publishing, 2021) Hossain, Akbar; Raza, Ali; Maitra, Sagar; Asaduzzaman, Md; Islam, Md Rafiqul; Hossain, Md Jamil; Sabagh, Ayman E. L.
    Phytohormones (PHs) play central roles in improving the survival ability of plants to various abiotic stresses. The major PHs are auxins, abscisic acid (ABA), gibberellins (GAs), jasmonic acid (JA), salicylic acid (SA), ethylene (ET), cytokinin (CK), and brassinosteroids (BRs), and nitric oxide (NO), polyamines (PA), and plant peptide are also considered as PHs. Besides them, newly identified PHs are strigolactones (SLs) and karrikins (KARs). Among them, SLs have been categorized as novel carotenoid-derived PHs, although they were primarily recognized as host-derived stimulating substances for germination of parasitic weeds under the genera Striga and Orobanche. Lately, SLs were established as host detection and hyphal-branching signals for arbuscular mycorrhizal (AM) fungi. In plants, they control numerous developing processes which lead plants to acclimatize to survive various abiotic stresses, particularly heat, drought, cold, salinity and waterlogging. In the last decade, the detection of SLs provides a novel prospect to reconnoitre PHs regulation of plant for advance and adaptation to ecological restrictions. Recent investigations also recognized novel examples of PHs cross talk contributing in the adaptation of inclusive rejoinders in plants. In this chapter, we have discussed the biosynthesis, signalling, governing, and physiochemical roles of SLs in numerous abiotic stress conditions. Therefore, it is revealed that the comprehensive thoughtful of SLs will be a significant issue for overwhelming the difficulties of crop damage as a consequence of hostile environments. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2021.
