In this manuscript, we investigate the existence of a unique solution to a boundary value problem (BVP) involving generalized fractional derivatives of the Caputo type. Our approach is grounded in the Banach contraction mapping theorem, which provides a rigorous framework for proving the existence of a fixed point and, consequently, a solution to the BVP. We extend this methodology to explore analogous problems, offering further insights and interpretations of the results derived from the main theorem. This work not only contributes to the theoretical understanding of fractional differential equations but also demonstrates how these techniques can be applied to a broader class of problems in mathematical physics and engineering. Through detailed analysis and extrapolation, we aim to establish a deeper connection between fractional calculus and fixed-point theory, providing a foundation for future research in this area.

This experiment investigated effects of seed priming and phosphorus fertilization on the biofortification of lentil plants grown under low-phosphorus field conditions. Four phosphorus doses and six priming treatments were used in the experiment. According to results, 15 and 30 kg P ha-1 significantly increased the nitrogen concentration in plants while all phosphorus doses stimulated greater magnesium accumulation over control. Higher phosphorus addition restricted potassium acquisition by 9.5% under high-potassium soils. Moreover, 15 kg P ha-1 application of salicylic acid, citric acid, inorganic phosphorus or plant growth-promoting bacteria (PGPB) distinctly promoted the uptake of nitrogen, phosphorus, potassium, manganese, iron and zinc. PGPB mostly promoted nitrogen and phosphorus uptake, while citric acid priming highly stimulated the acquisition of Mg, Mn and Fe. All priming treatments were lower than the control for potassium accumulation, in which the lowest value was observed in PGPB-primed plants, because it can solubilize phosphorus compounds in rhizosphere, thereby causing an antagonistic effect on potassium uptake. Seed priming with 4 mM silicon enhanced copper accumulation in tissues up to 9.4%. Priming with 100 mg kg-1 citric acid promoted iron, magnesium and manganese accumulation by 13.8%, 3.8% and 4.7% compared with control, respectively. In conclusion, phosphorus addition boosted macro-and micronutrient acquisition, although the 15 kg P ha-1 dose is recommended from an economic perspective. Also, phosphorus application and seed priming treatments exhibited synergistic effects on nutrient acquisition depending on a nutrient element. Finally, seed priming with PGPB, 4 mM salicylic acid and 100 mg kg-1 citric acid exhibited superior performance on nutrient uptake in lentil.

Sustainable bioenergy production from dedicated crops has garnered considerable attention in recent years as a potential solution to mitigate greenhouse gas emissions and meet growing energy demands. The carbon-to-nitrogen (C:N) ratio, a fundamental biochemical parameter, plays a pivotal role in the productivity and quality of bioenergy crops. This chapter explores the multifaceted significance of the C:N ratio in bioenergy crop development. Beginning with a comprehensive understanding of the C:N ratio, this chapter delves into its influence on plant biomass production and its subsequent implications for bioenergy conversion processes. We discuss strategies for managing C:N ratios in bioenergy crops, encompassing fertilization, nutrient management, and crop selection. Real-world case studies and research findings illustrate successful C:N ratio management approaches and their practical applications. Environmental considerations are paramount in the cultivation of bioenergy crops, and this chapter evaluates the impact of C:N ratios on soil health, carbon sequestration, and sustainability. Moreover, it addresses the role of policy and regulation in shaping bioenergy crop development, emphasizing the relevance of C:N ratios in policy decisions. Finally, the chapter explores emerging trends and challenges in the field, highlighting future research directions and technological innovations. This comprehensive overview underscores the central importance of the C:N ratio in developing effective bioenergy crops and underscores its potential to contribute to a sustainable energy future.

Forages are an important source of nutrition and health benefits for dairy animals. Forage growth, nutritional quality, biomass, and yield are important agronomic traits that are severely impacted by a number of abiotic stresses, including drought, salinity, and chilling injury. The impact of these diverse stresses on fodder crops has received comparatively little attention. To address these issues, we presented a thorough analysis of the negative effects of abiotic stresses in this chapter, as well as farmer-friendly agronomic management techniques such as nitrogen fertilizer application, irrigation management, and optimizing soil conditioning through tillage to conserve moisture and increase soil water retention capacity. These approaches would particularly help to ensure water supply, biomass production, and drought stress alleviation. To aid in the recovery of saline, sodic, and saline-sodic soils, calcium (Ca2+) and magnesium (Mg2+) enhanced fertilizers should be used instead of Na+, and salt leaching should be permitted through frequent irrigations. Heat-tolerant/adaptive cultivars can minimize crop-growing areas while protecting plants, soils, and the environment from the harmful impacts of abiotic stresses. Abiotic stress damage to forage crops can be significantly reduced by cultivating N2-fixing legume forages, introducing environmentally friendly plant-nutrient benefit-providing symbionts, and using organic amendments such as plant growth-promoting microbes (PGPM), biochar, mineral nutrition, and organic acids (OA). Furthermore, these methods create new prospects for smart and sustainable agriculture.

The global energy landscape is increasingly shifting toward sustainable and renewable energy sources, with biofuels emerging as a viable alternative to fossil fuels. This chapter examines the critical role of carbon partitioning (CP) and resource use efficiency (RUE) in enhancing biofuel production. Carbon partitioning, the process by which plants allocate assimilated carbon to various metabolic pathways and tissues, is pivotal in determining the yield and quality of biofuel feedstocks. Optimizing carbon allocation can significantly increase the proportion of biomass directed toward biofuel precursor compounds, such as cellulose, hemicellulose, and lipids. Moreover, the efficiency of resource use, particularly light, water, and nutrients, is essential for maximizing biomass production in a sustainable manner. Advances in genetic engineering and crop management practices have shown promise in improving both CP and RUE. Techniques such as CRISPR/Cas9-mediated gene editing and the development of transgenic crops have enabled precise manipulation of metabolic pathways to enhance biofuel precursor accumulation. Additionally, agronomic practices, including optimized irrigation and fertilization regimes, can further augment biomass yield and quality. This chapter also explores the potential of integrating multi-omics techniques, including genomics, transcriptomics, proteomics, and metabolomics, to gain a comprehensive understanding of the underlying mechanisms governing CP and RUE. These insights can inform the development of next-generation biofuel crops with superior performance under diverse environmental conditions. Furthermore, we explore the financial feasibility and ecological impact of biofuel production in light of these advancements, emphasizing that enhancing CP and RUE presents a promising strategy for optimizing biofuel yield and sustainability. Future research should focus on the integration of advanced biotechnological tools and sustainable agronomic practices to achieve high-yielding, resource-efficient biofuel feedstock.
