“…Root architecture parameters were recorded by WinRHIZO software (WinRHIZO Pro, Regent Instruments, QC, Canada) including total root length, root surface area, root volume, average root diameter, and the number of root tips. The exaction and determination of nonstructural carbohydrates (hexose, sucrose, and starch) were conducted following our previous protocols 26 , 27 . Total carbon in seedling organs was determined using Multi N/C 2100 analyzer with HT 1300 solid module (Analytik-Jena, Germany) and total nitrogen using the Kjeldahl method.…”

Red soil is characterized by poor physico-chemical properties and low nutrient availability. The present study aimed to examine rich husk ash (RHA) incorporation into red soil at various rates effects on its properties and the growth of cotton seedlings under a plug-seeding in tray experiment. Bulk density was decreased, and water holding capacity and total porosity were increased in red soil with increasing application rate of RHA. The addition of RHA counteracts the acidity of red soil and improves the nutrient availability to plants. The RHA incorporated soils favored the growth of cotton seedlings with improved shoot morphological traits and root architectures. The application rate at a volume ratio of 1:1 of RHA to red soil was found to be optimal for growing cotton seedlings in the present study. The mixture of RHA and red soil at a 1:1 volume ratio plus 2 g L−1 super absorbent polymers exhibited a high nursing seedling efficiency comparable to a commercial growing media under the condition of foliar application of mepiquat chloride at the one-true-leaf stage. RHA can be a promising substitute for peat as growing media for nursing cotton seedlings.

“…Crop management practices are another way to improve fiber quality and quantity while maintaining lint yield. It is worth pointing out that lint yield is negatively related to fiber quality and accessing methods to increase fiber quality while preserving cotton yield have become the focus of studies (Luo et al, 2019;Keshavarz, 2020).…”

Choosing suitable varieties and manipulating plant population are crucial management aspects in any cropping system that goals to improve yield, quality and the balance between plant demand and environmental resource availability. A two-year field experiment was conducted at Tehran, Iran, in a split plot design and replicated thrice to examine the effect of the planting density (low, moderate and high) on ten cotton genotypes. In term of lint yield and among the cotton genotypes G8 (1269 kg · ha−1), G4 (1263 kg · ha−1), G1 (1239 kg · ha−1) and G2 (1123 kg · ha−1) were statistically at par with each other but significantly superior to G7 (914 kg · ha−1) and G9 (936 kg · ha−1). Lint yield in high plant density (1386 kg · ha−1) was found to be remarkably superior over medium and low plant density (1029 and 890 kg · ha−1, respectively) by average of 25.7% and 35.7%, respectively. Cotton genotypes at low plant density had higher boll plant−1 (6.46% and 15.3%, respectively), lint percentage (5.8% and 12%, respectively) and lint strength (0.6% and 1.9%, respectively) compared to moderate and high plant densities. The genotypes cultivated at high plant density produced higher seed and lint yield, higher lint elasticity and lower seed oil content, lint length and lint quality index. Based on this experiment, it is concluded that high seed cotton yield can be achieved at high plant density while higher lint quality can be yielded at low plant density.

“…The chlorophyll concentration in the supernatant was spectrophotometrically determined by measuring the absorbance at 665 nm and 649 nm for Chl a and Chl b, respectively. The formulas for the calculation of chlorophyll concentration were as follows: Chl a = 13.95*A 665 -6.88*A 649 ; Chl b = 24.96* A 649 -7.32*A 665 carbohydrate analysis Nonstructural carbohydrates, such as glucose, fructose, sucrose, and starch, were extracted and quanti ed following previous procedures (Luo et al, 2019;Chen et al, 2020). Total nonstructural carbohydrate (TNC) concentration was de ned as the sum of glucose, fructose, sucrose, and starch concentrations.…”

Background Mepiquat chloride (MC) application and increasing plant population density (PPD) are required for modern cotton production. However, their interactive effects on leaf physiology and carbohydrate metabolism remain obscure. This study aimed to determine how MC and PPD affect the leaf morpho-physiological charateristics, and thus final cotton yield. PPD of three levels (D1: 2.25 plants m-2, D2: 4.5 plants m-2, and D3: 6.75 plants m-2) and MC dosage of two levels (M0: 0 g ha-2, M1: 82.5 g ha-2) were combined to create six treatments. The dynamics of nonstructual carbohydrate concentration, carbon metabolism-related enzyme activity, and photosynthetic attributes in cotton leaves were examined during reproductive growth in 2019 and 2020. Results Among six treatments, the high PPD of 6.75 plants m-2 combined with MC application (MC1D3) exhibited the greatest seed cotton and biological yields. The sucrose, hexose, starch, and total nonstructural carbohydrate (TNC) concentrations peaked at first flowering (FF) stage and then declined down to a minimum at first boll opening (FBO) stage. Compared to the other treatments, MC1D3 improved starch, and TNC concentrations by 5.4–88.4%, 7.8–52.0% in 2019, and by 14.6–55.9%, 13.5–39.7% in 2020 at the FF stage, respectively; Additionally, The treatment produced higher transformation rates of starch and TNC during the FF to FBO stages, indicating greater carbon production and utilization efficiency with it. MC1D3 displayed the maximal SLW at the FBO stage, and the greatest Chl a, Chl b, and Chl a + b concentrations at the mid-late growth phase in both years. The Rubisco activity with MC1D3 was 2.6–53.2% higher at the flowering and boll setting stage in both years, and 2.4–52.7% higher at the FBO stage in 2020 than those in the other treatments. These results provided a explanation of higher leaf senescence-resistant ability in MC1D3. Conclusion Increasing PPD coupled with MC application improves cotton yield by enhancing leaf carbohydrate production and utilization efficiency and delaying leaf senescence.
