Abstract

Drought is one of the major limiting factors in the cultivation of peanut (Arachis hypogaea L.), particularly in dryland and marginal areas. This study aims to evaluate the adaptive responses of peanut plants to drought stress through a comprehensive literature analysis. The approach combines a narrative review and meta-analysis of scientific studies published between 2010 and 2024. The analysis revealed that drought during the generative phase can reduce yield by up to 70–80%. Peanut plants exhibit various adaptive mechanisms, including root elongation, stomatal closure, increased activity of antioxidant enzymes (CAT and APX), accumulation of osmolytes (proline and agmatine), and enhanced levels of stress-related hormones such as abscisic acid (ABA). In addition, agronomic techniques such as seed priming with melatonin have been proven effective in enhancing drought tolerance by improving photosynthetic efficiency and cellular protection. This study highlights that the drought tolerance of peanut plants is a complex interaction between morphological, physiological, and molecular factors. Therefore, selecting drought-tolerant cultivars and applying adaptive cultivation technologies are key strategies for maintaining productivity under water-limited conditions.

Abstract

This research examines the causes of the lack of nutrients in red chili plants (Capsicum annuum L.) and how to properly maintain them. Using qualitative descriptive research methods, this study was conducted in Dahadano Botombawo Village, Hiliserangkai District, Nias Regency for 3 months. Research results show that deficiencies in key nutrients such as nitrogen, phosphorus, potassium, calcium and magnesium can cause various symptoms in chili plants, including stunted growth and reduced fruit quality. Factors such as environmental conditions, soil quality, pest and disease attacks, and inappropriate cultivation practices also contribute to delayed plant growth. Proper maintenance, including selecting quality seeds, good soil cultivation, appropriate fertilization, and integrated pest and disease control, is very important to increase the productivity of red chili plants.
