have a fibrous root structure, which makes them sensitive to drought, so it is important to avoid excessive irrigation during cultivation [10]. The Food and Agriculture Organization (FAO) reported that the global fresh vegetable production reaches 1.1 billion tonnes. Turkey ranks fourth in the world with a vegetable production of 38.1 million tons. The production of peppers is increasing worldwide, with Turkey being the second largest producer at 3,091,295 tons, following China [11]. The Turkish Statistical Institute [12] reports that capia pepper makes up 46.8% of total pepper production, with a total of 1,445,275 tons. Capia pepper has many uses in the food industry, including in paste, canned goods, pickles, ketchup, roasted products, pepper juice, ready-made soups, and the food-drying sector [13]. The global population is predicted to reach between 9 and 11 billion by 2050 [14]. This rapid increase in population highlights the need for more effective and planned utilization of limited clean water resources. Studies indicate a six-fold increase in global water demand over the past 100 years [15]. Therefore, sustainable management of water resources has become a crucial issue, particularly in the agricultural sector. Water is an essential part of agriculture, and the rising demand for food, driven by population growth, increases the need for water for farming activities. However, the depletion and contamination of water sources threaten agriculture's sustainability [16]. Treating polluted water for agricultural use is a significant strategy to efficiently utilize water resources and mitigate the environmental impacts of agriculture. According to [PERSON] et al. [17], research predicts that Turkey will experience the most significant effects of climate change on water usage by 2070 compared to France, Spain, Italy, Greece, and Ukraine. Pepper cultivation is often limited by water resources in warm and semi-arid regions; thus, optimum water management is required for pepper irrigation in these regions [18]. Water and nitrogen are critical factors determining pepper yield and quality [19]. Another study reported a decrease in capia pepper yield in response to increased levels of soil water stress [20]. Water stress leads to a significant reduction in nitrogen absorption by pepper plants [21]. Studies have been conducted on pepper and other vegetables where high-frequency drip irrigation andrifugation improved yields [22; 23; 24; 25]. Over-watering can lead to diseases such as root rot in peppers and cause essential plant nutrients to leach away from the root zone. In pepper cultivation, it is important to use frequent, small-scale irrigation [26; 27]. Insufficient soil moisture during the flowering period can cause flower drop, resulting in a reduction in fruit quantity, and during the fruit-setting period, it can cause shape deformities [28]. Protecting and increasing soil moisture has been frequently researched worldwide [29]. In addition to alternative irrigation strategies, different soil improvement practices have become compulsory to save irrigation water and fertilizer [30]. The advantages of using wastewater extend beyond its application as irrigation water. Its components, such as nitrogen and phosphorus, can reduce the fertilizer requirement in agriculture. However, using untreated wastewater for agricultural purposes carries certain risks. Some substances present in wastewater can adversely affect the environment and plant health. Reclaimed water irrigation, while posing risks related to salinity and heavy metals, can be effectively managed through appropriate irrigation and agricultural practices. Reclaimed water contains a variety of fecal indicators and environmental pathogens, making reducing and controlling microbial contamination crucial [31; 32; 33; 34]. Before utilizing wastewater for irrigation, it is essential to conduct thorough suitability analyses and implement them carefully. If wastewater is to be used for irrigation, drip irrigation systems are preferable over sprinkler irrigation methods.
