Soil fumigation is commonly employed for pest control in potato production, although it can unintentionally harm non-target organisms in the soil. The presence of cover crops can significantly influence the abundance and composition of microorganisms. However, there is limited knowledge regarding the combined impact of soil fumigation and cover crops on soil health in potato fields. To address this knowledge gap, a field study was conducted at the Hermiston Agricultural Research and Extension Center, Oregon State University with a randomized split-plot design consisting of four fumigation treatments (no fumigation control, Telone, metam sodium, and co-applied Telone and metam sodium) as the main plots and five cover crop treatments [no cover crop, wheat (Triticum aestivum), mustard (Brassica nigra), radish (Raphanus sativus), and a mixture of winter pea (Pisum sativum) and faba bean (Vicia faba)] as the subplots. Compared to the control, microbial biomass carbon (MBC) in non-fumigated soils of pea+faba bean, wheat, and radish increased by 41 %, 37 %, and 31 %, respectively. In soils treated with metam sodium, pea+faba bean, wheat, radish, and mustard increased MBC by 30 %, 34 %, 41 %, and 40 % compared to the control. The results demonstrated the potential of cover crops to enhance MBC after fumigation. Both Fumigation and cover crop did not impact the total yield of potatoes, although fumigation increased the yield of tubers within 171-283 g size category compared to the control. However, the current data is not sufficient for making a conclusive remark. Further field studies should be conducted to understand the role of fumigation and cover crops on potato soil health and potato production.

Climate change poses significant challenges to livestock production worldwide. Wherein, it affects communities in developing nations primarily dependent on agriculture and animal husbandry. Its direct and indirect deleterious effects on agriculture and animal husbandry includes aberrant changes in weather patterns resulting in disturbed homeorhetic mechanism of livestock vis a vis indirectly affecting nutrient composition of feed and fodder. The nutritional stress (i.e. non-availability of nutrients in the required quantity and quality for particular livestock) is the critical factor affecting livestock performance, productivity, and reproductive efficiency. Nutritional stress may arise from both macro- and micro- nutrient imbalances; however, micronutrients are of paramount importance in climate change context due to their role in various vital functions of body namely, body metabolism, production, reproduction, and health. The micronutrients, minerals and vitamins, when supplied in adequate quantity and proportion aid in mitigating the stress induced by climate change on animals. Here, we tried to discuss the impact of climate change induced stresses on milk production, reproduction, and metabolic acclimation of heat-stressed animals. Furthermore, emphasis is given on the importance of dietary micronutrients management strategies to support livestock health and resilience during changing climatic conditions. By addressing the nutritional needs of livestock, farmers can achieve sustainability and well-being in livestock production under changing climatic condition.
