“…A future study could further improve DSI by effectively considering this time lag in order to more reliably evaluate and monitor drought. Second, the dryness/wetness condition is normally considered as the dominant factor that impacts crop yields in semi-arid areas, but other factors, such as fertilizer, climatic anomalies, or economics also play roles in the agricultural production (Chen et al, 2015;Salehnia et al, 2020). The use of a single factor only permits the assessment of its impact on yield, rather than yield prediction.…”

“…While, cotton production has decreased because of various factors the most significant of which being environmental concern (Ahmad et al, 2016). Thus, Salehnia et al (2020); Ahmad et al (2020); Arshad et al (2021) who indicated that drought is one of the most serious climatic challenges that may harm agricultural productivity. Most of field crops, particularly cotton, need a large amount of water and additional irrigation for optimal cultivation and growth in dry climates.…”

“…There are some commonly used meteorological drought indices, such as Percentage of precipitation anomaly [13], Palmer drought severity index [14], Standardized precipitation index [15], Compound index, Relative humidity index, Reconnaissance drought index [16], Standardized precipitation evapotranspiration index (SPEI) [17], etc. Among them, SPEI not only has multi-timescale characteristics of a standardized precipitation index but also reflects the effects of global temperature change on drought, which is not only a good index for monitoring meteorological drought [18] but has also been widely used to monitor agricultural drought and analyze the impacts of crops due to drought [10,19,20]. For example, Pena-Gallardo et al [21] found that there were significant correlations between wheat yields and the SPEI at timescales ranging from 1 to 18, particularly over the second half of the year in the counties of Eastern United States.…”
