“…Irrigations were scheduled based on a soil‐matric potential of about −90 kPa at 60 cm soil depths in the FI irrigation plots as recommended by Plumblee et al. (2019). In 2018, a total of 220 mm of irrigation was applied in the FI treatments in four irrigation events of 55 mm each applied through every furrow on 15 May, 20 June, 6 July, and 3 August, while the HI treatments received about half the amount of water on the same dates but in every other furrow, amounting to total water applied of about 115 vs 220 mm in the FI.…”

“…In an attempt to fill this gap in scientific research in the Mississippi Delta region, Plumblee et al. (2019) reported an increase in IWUE in cotton ( Gossypium L.) of 61% after adopting an irrigation schedule that triggered irrigations at −90 kPa matric water potential in 100‐cm soil depth. Although the physiological and agronomic advantages of a TR soybean production system compared with an SR system have been thoroughly researched, no information on the IWUE of a TR over an SR planting geometry was reported for the Mississippi Delta (Plumblee et al., 2019).…”

Twin-row planting in soybean (Glycine max L.) has been proposed for optimizing resource use and seed yield. Experiments were conducted in 2018 and 2019 on a Dundee silt loam to assess soybean seed yield and irrigation water use efficiency (IWUE) in response to single-row (SR) and twin-row (TR) planting geometries under rainfed (RF), all row or full irrigation (FI), and alternate row or half irrigations (HI). Averaged across two crop years and three irrigation regimes, TR enhanced seed yield by 13% over SR (4.5 vs. 4.0 Mg ha −1). The final plant stands established in the FI, HI, and RF under TR were 32, 33, and 31 plants m −2 , whereas 30, 31, and 27 plants m −2 were established under SR. Under both SR and TR, irrigations produced a higher number of pods per plant than of RF. Averaged across crop years, yields in the irrigation-planting geometry combinations were 4.8 Mg ha

“…Lack of scientific research that enhances irrigation water use efficiency (WUE) was attributed as one of the primary reasons for the depletion (Clark et al, 2011). Plumblee et al (2019) reported an increase in WUE by 61% by adopting a matric water potential sensor-based irrigation at -90 kPa average in a 100-cm soil depth in MS Delta. Pettigrew and Zeng (2014) reported a 25% increase weeds, followed by disc-tillage to generate furrows and ridges (102-cm row spacing) for planting cotton seeds and facilitating furrow irrigations.…”

Addressing the challenges of dwindling groundwater resources and ever-increasing demands for water necessitate enhancing water use efficiency (WUE) in irrigated agriculture. In a 2-year study, we examined the effects of different levels of irrigation and PG on lint yield and WUE of furrow irrigated cotton in a Dundee silt loam in the Mississippi Delta. The main plots were three irrigation regimes: irrigating every furrow (FI), alternate furrow (HI), and no irrigation (RF) and subplots were two planting geometries (PG): single-row (SR) and twin-row (TR). Across FI and HI no significant differences were observed in plant height and biomass yield at flowering, but chlorophyll content index and leaf area index (LAI) were positively affected. Canopy closure in TR planting occurred earlier than SR leading to higher leaf areas available for harvesting more light during photosynthesis. Averaged across the irrigation regimes, the TR planting enhanced lint yield by 10.6% in 2018 and 17.6% in 2019 compared to SR. The average lint yield in SR and TR were: 1779 and 2028 kg ha-1 under FI, 1803 and 2082 kg ha-1 under HI, and 1573 and 1788 kg ha-1 under RF treatments, respectively. In FI and HI treatments, TR had higher lint yield than RF treatment by 13.8% and 16.5%, respectively. Lint yield in HI with TR had the highest irrigation WUE (3.4 kg ha-1 mm-1) followed by HI with SR (2.7 kg ha-1 mm-1). These results demonstrated that cotton grown in TR with HI could reduce irrigation water demand in silt loams.

“…Sensors for measuring soil-matrix water potential (Watermark sensors, Irrometer Company, Inc, Riverside, CA USA) were installed at soil depths of 15, 30, and 60 cm in selected representative plots. Irrigations were scheduled based on a soil matrix potential of about − 90 kPa at 45 cm soil depths, as recommended by Plumblee et al (2019). The amount of irrigation water applied during each season in each plot was measured using a ow meter.…”

Background: Cotton fiber quality and seed composition play vital roles in the economics of cotton production systems and cotton seed meal industry. The objective of this research was to examine the effects of different levels of irrigation and planting geometries on fiber quality and seed composition of cotton (Gossypium hirsutum L.). A two-year study was conducted in 2018 and 2019 on a Dundee silt loam soil in the Southeast USA with a warm and humid climate. Irrigation treatments were, irrigating every furrow (FI, full irrigation) and alternate furrow (HI, half irrigation), and no irrigation (RF, rainfed), and planting geometries were a single-row (SR) and twin-row (TR) on ridges spaced 102 cm apart. Fiber quality was tested by using the High-Volume Instrument (HVI) and Advanced Fiber Information Systems (AFIS). Seed protein, oil, and fiber were estimated using near-infrared reflectance spectroscopy. Results: The results showed irrigation and planting treatments played a significant role in fiber quality and seed composition. Across irrigation treatments, significant differences were seen in fiber properties, including micronaire, uniformity, upper half mean length (UHML), strength, yellowness, short fiber, upper quartile length (UQL), fineness, maturity ratio, and neps. The micronaire was negatively affected by irrigation as FI-SR, FI-TR, HI-SR, and HI-TR had recorded 11-12% over the RF-SR and TR treatments. The planting geometry played a minor role in determining fiber quality traits like micronaire and nep count. Irrigation treatments recorded significantly lower protein content by 3-4 % than rainfed, while oil content significantly increased by 6-10 %. Conclusions: The results of the study indicate a potential for improving cotton fiber and seed qualities by managing irrigation and planting geometries in cotton production systems in the Mississippi Delta region.
