“…Typically, cotton yield increases with an increase in N fertilizer until it reaches an optimum level, beyond which additional N fertilizer does not affect yield and most probably results in wasted expenses and negatively impacts soil health [50,51]. The obtained data of the study showed that the reduction of the fertilizers to the half dose recommended did not affect either yield or technological parameters and are in accordance with [13,52], who proposed that cotton productivity is highly dependent on a cultivar's genetics and highlighted that N fertilizer application rates could be reduced based on updated crop requirements, without yield penalty due to the different requirements of newer cotton cultivars.…”

“…On the other hand, nitrogen is a critical element for cotton growth and development [13] and nitrogen fertilization has significant impacts on cotton growth, boll development, lint yield, and fiber quality [14]. Nitrogen fertilizer has been shown to significantly impact cotton growth, affect the physiological characteristics of cotton, and eventually determine the final yield and quality.…”

Cotton, a high-value crop of primary financial importance for Greece, is directly affected by a wide range of environmental parameters, and water scarcity threatens the sustainability of irrigated cotton production in many regions around the world. Reducing inputs with an appropriate cultivar may not decrease cotton production and fiber quality while improving sustainability. To investigate cotton varietal responses to water stress and lack of nutrients, in the climate of north Greece, a three-year experiment was conducted in Thessaloniki, Greece. Four cotton cultivars (three of Greek origin and one from Africa) were cultivated under four irrigation (normal and reduced by 75%, 50%, and 25%) and two fertilization levels (normal and 50%). The effect of these treatments on productivity and quality were estimated, with the final objective being the reduction of inputs and more sustainable cotton production. Cotton producers are dealing with a cost price squeeze and the present study demonstrates that reducing the fertilization inputs even by half and the reduction of irrigation by 25% has no significant effect neither on yield nor on the main technological characteristics. This highlights the fact that a more sustainable use of inputs, contrary to common management, will have almost the same yield and even increase the farmer’s income.

“…'s (2023) investigation found that irrigation had no impact on total node count at FB. However, previous research tested N fertilizer, which significantly influenced total nodes (Main et al., 2013; Pabuayon et al., 2021; Shah et al., 2021). Regardless of the SMU, the year 2016 exhibited the lowest node count, ranging between 10 and 13 nodes per plant.…”

Cotton (Gossypium hirsutum L.) cultivars vary in their response to environmental factors. Recently, interest in cotton cultivars' response to varying potassium (K) fertilizer application rates and irrigation has increased. As such, the effect of cotton varieties (early and mid‐maturing), K fertilizer application rates, and irrigation on cotton growth, development, and yield were investigated in Starkville, MS, on two soil mapping units (SMUs): a Leeper silty clay loam (LSCL) and a Marietta fine sandy loam (MFSL). Cotton plant height was positively correlated with SMU, especially LSCL, reaching 60–110 cm on average, in both irrigated and rainfed conditions. Cotton lint yield, fiber quality, and leaf K concentration responded to K and irrigation, and these responses were SMU specific. Particularly, in LSCL, the early‐maturing cultivar, DP 1518 B2XF, responded to K application rate in a positive linear manner in terms of lint yield under both irrigated and rainfed conditions, whereas mid‐maturing DP 1646 B2XF did not. Moreover, lint yield in irrigated MFSL soil increased with K application rate, whereas no responses were observed in rainfed conditions. These data suggest that irrigation, SMU, and cultivar combination could have an impact on K response of cotton and should be considered when making fertility recommendations or decisions.

“…Total N applications averaged 82, 102, and 114 kg ha -1 for the 33%, 66%, and 100% irrigation levels, respectively, across the three study years. Applications of N at greater than optimal rates at given irrigation levels were avoided to prevent vegetative growth and diminished availability of assimilates required for fruiting structure development that would reduce yield potential (Main et al, 2013;Pabuayon et al, 2021).…”

Highlights In-season crop water use and canopy temperatures after first square did not differ among cultivars. Lint yield was significantly affected by cultivar in all study years. Cultivar effects on lint yield were significant only at higher irrigation levels. Crop water productivity increased with increasing irrigation in two of the three study years. Abstract. Upland cotton (Gossypium hirsutum L.) production requires less irrigation compared with other crops and thus provides an opportunity to reduce risk and maintain profitability in areas where water is limited. Water use, canopy temperature, lint yield, and crop water productivity were evaluated for four early to medium maturity upland cotton cultivars under three levels (100%, 66%, and 33%) of alternate furrow subsurface drip irrigation (SDI) in a thermally limited environment. Crop evapotranspiration (ET) across cultivars and years averaged 627, 547, and 467 mm for the 100%, 66%, and 33% irrigation levels, respectively, and did not differ among cultivars (P > 0.05). Changes in stored soil water within each irrigation level were similar among cultivars, with significant differences occurring infrequently. Measured canopy temperatures from first white flower to two weeks after cutout did not significantly differ among cultivars (P > 0.10) within each irrigation level. Crop water use during boll maturation, as inferred from the developed crop coefficient curve, was considerably less than reported by other studies, signifying that irrigation could be terminated earlier without reducing lint yield. The cultivar effect on lint yield was significant in all study years (P < 0.001), but only at the 66% and 100% irrigation levels, with one cultivar exceeding the average yields of all evaluated cultivars by 13% across the three study years. Medium maturity cultivars usually yielded less than early maturity cultivars, especially for a year with less accumulation of thermal energy. Crop selection and late season irrigation water management were both key to improving cotton water productivity. Keywords: Upland cotton, Subsurface drip irrigation, Water productivity, Root water uptake, Canopy temperature.
