In such cases, meta-analyses must be used to analyze summary data. The aim of current systematic review and meta-analysis is to investigate effects of g.17,924 A > G SNP on some fatty acid composition in the muscle of cattle. A total of 11 studies from 2007 to 2023 were included in the comprehensive search. Three co-dominant models (AA versus AG), (AA versus GG), and (AG versus GG) were used to analyze data. The standardized mean difference (SMD) was used to measure the size effects of the A and G alleles of g.17,924 A > G polymorphism on fatty composition. 95% confidence intervals were calculated using random/fixed effect models. Heterogeneity among studies and statistical stability of overall estimates were assessed using I2 tests by Stata 11.2 software. Higher heterogeneity was observed among the studies showed higher genetic diversity. The results of this meta-analysis showed significant association between g.17,924 A > G SNP and Oleic acid (C18:1), myristic acid (14:00), myristoleic acid (14:0). and monounsaturated fatty acids (MUFA) (<i>P</i> < 0.01). No Significant association revealed between g.17,924 A > G SNP and linolenic acid (C18:3).

The use of conventional phosphorus fertilizers is hampered by their low solubility, high fixation in soils, and significant leaching losses, which lead to poor nutrient use efficiency and the environmental issues of P build up and eutrophication. In this context, calcium phosphate nanofertilizers (CaP NFs) have emerged as a promising alternative aligned with the goals of sustainable and climate-resilient agriculture. This review comprehensively examines the potential of CaP NFs to improve phosphorus uptake, minimize nutrient losses, and in compliance with soil health. In this context, calcium phosphate nanofertilizers (CaP NFs) have emerged as a promising alternative for improving nutrient use efficiency and minimizing nutrient losses. Evidence from recent studies indicates that CaP NFs support enhanced germination, biomass accumulation, stress resilience, and yield, especially under phosphorus-deficient or abiotic stress conditions. Beyond nutrient delivery, CaP NFs also serve as carriers for other macro- and micronutrients, enabling controlled release and reducing fertilizer application frequency. We discuss modes of application (soil, foliar, hydroponic), potential for integration with organic amendments, and field-scale feasibility. Environmental and regulatory concerns, particularly nanoparticle toxicity, standardization gaps, and cost barriers, are addressed in the context of agriculture in India. Finally, we propose policy and research interventions needed to facilitate large-scale adoption of CaP NFs, including capacity building, subsidy realignment, and inclusion in nutrient management frameworks. This review demonstrates that the synthesis methods of CaP NFs, their ability to act as carriers for multi-nutrients, and their capacity for controlled release position them as a viable route to enhancing phosphorus use efficiency in agriculture.</p></div>","PeriodicalId":7553,"journal":{"name":"Agricultural Research","volume":"15 1","pages":"1 - 14"},"PeriodicalIF":1.1,"publicationDate":"2025-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147559895","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The suitability of data for PCA was confirmed through the Kaiser–Meyer–Olkin (KMO) measure and Bartlett’s Test of Sphericity.

It is grown under diverse agro-ecological conditions, including early, timely, and late sown, irrigated, and rainfed systems. However, climate change and challenging agro-ecologies like rainfed and late sown cultivation cause significant yield losses due to abiotic stresses. Developing climate-resilient genotypes is crucial to mitigate these issues. This study aimed to identify stable genotypes for seed yield using GGE biplot analysis of 35 mustard genotypes over three rabi seasons, <i>rabi</i> 2020–21 (20–21), <i>rabi</i> 2021–22 (21–22) and <i>rabi</i> 2022–23 (22–23), under three agro-ecologies, timely–irrigated (T-IR), timely–rainfed (T-RF) and late sown–irrigated (LS-IR). Analysis of variance showed significant genotypic variation in seed yield per plant, with crossover interactions indicating substantial genotype-by-environment interactions (GEI). The GGE biplot’s PC1 and PC2 explained 60.70% of the total G + GE variation. E7 (T-IR 22–23) was the most discriminative environment, while E6 (LS-IR 21–22) was the most representative.
