    Impact of Weed Competition on Morphological and Biochemical Traits of Potato: a Review
    (Springer, 2024) Siddiqui, Ahmad Omid; Isik, Dogan; Jabran, Khawar
    Potato (Solanum tuberosum L.) is the fourth major crop grown as a staple food worldwide, following rice, wheat, and maize. It is highly susceptible to diseases, nematodes, insect pests, and weeds. Potato yield loss due to weeds varies from 10 to 80% depending on the environment, weed diversity, density, and period of the weed-crop competition. High weed interference may decrease 65% of marketable tuber yield by reducing the number and size of marketable tubers. Weeds not only decrease potato tuber yield but also negatively influence the antioxidant enzymatic activity and primary metabolites of the potato plant. Estimates have shown that the starch content of potato tuber decreases by 10% and protein content by 36% in potato-weed competition. These findings suggest that weed competition can substantially impact potato growth and development and that effective weed management strategies are critical for optimizing potato yields and quality. This review summarizes the recent progress on how potato plants initially respond to weed interference at morphological, biochemical, and physiological levels.

    Weed management and climate change
    (Springer International Publishing, 2021) Siddiqui, Ahmad Omid; Yazlik, Ayşe; Jabran, Khawar
    Weeds and their management are being affected by warming of the earth and rise in carbon dioxide (CO2) levels in the atmosphere. Evidence from the recent literature confirms that high carbon dioxide in the atmosphere will increase the growth of weeds particularly the C3 weeds. Warming on the other hand will support several weeds to expand their range and establish into new areas. Further, high levels of warming and CO2 may also have a negative effect on the efficacy of several herbicides. Under this situation, use of cultural and mechanical weed control will be important. No doubt, these and other nonchemical weed control methods can be integrated with herbicides to achieve effective control of weeds under changing climate. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2022.

    Weed management in potato
    (Elsevier, 2022) Jabran, Khawar; Ahmad, Taseer; Siddiqui, Ahmad Omid; Üremiş, İlhan; Doğan, Mehmet Nedim
    Potato is one of the most important staple foods in the world. Weeds are important among the several constraints that limit the potato production in different parts of the world. Weeds not only suppress plant growth but also reduce final yield and decrease quality of the potato products. Effective weed control is compulsory to achieve high yield and quality in potato production. This chapter covers important weeds that infest the potato fields and compete for nutrients and other resources and cause losses in both yield and quality. Further, the chapter also covers the degree of yield losses that occur due to weed infestation. The chapter also discusses the control methods (preventive, cultural, mechanical, chemical, and integrated weed management) that are most adopted and suitable for weed control in potato. © 2023 Elsevier Inc.
