“…Fiber quality is a main aim of cotton breeders both because fiber traits directly affect lint yield and improvement in spinning technology has an increased demand for high-grade fiber [ 43 ]. Fiber quality is the combination of fiber length, fiber fineness (cell wall thickness), fiber strength, fiber elasticity, neps (small nodules on the fiber), short fiber index, uniformity index, spinning consistency (suitability of fibers for yarn-spinning), color grade, and reflectance (brightness of fibers) [ 44 ]. Fiber quality traits are quantitative and controlled by multiple genes with major and minor phenotypic effects [ 45 ].…”

Coping with drought: stress and adaptive mechanisms, and management through cultural and molecular alternatives in cotton as vital constituents for plant stress resilience and fitness

Increased levels of greenhouse gases in the atmosphere and associated climatic variability is primarily responsible for inducing heat waves, flooding and drought stress. Among these, water scarcity is a major limitation to crop productivity. Water stress can severely reduce crop yield and both the severity and duration of the stress are critical. Water availability is a key driver for sustainable cotton production and its limitations can adversely affect physiological and biochemical processes of plants, leading towards lint yield reduction. Adaptation of crop husbandry techniques suitable for cotton crop requires a sound understanding of environmental factors, influencing cotton lint yield and fiber quality. Various defense mechanisms e.g. maintenance of membrane stability, carbon fixation rate, hormone regulation, generation of antioxidants and induction of stress proteins have been found play a vital role in plant survival under moisture stress. Plant molecular breeding plays a functional role to ascertain superior genes for important traits and can offer breeder ready markers for developing ideotypes. This review highlights drought-induced damage to cotton plants at structural, physiological and molecular levels. It also discusses the opportunities for increasing drought tolerance in cotton either through modern gene editing technology like clustered regularly interspaced short palindromic repeat (CRISPR/Cas9), zinc finger nuclease, molecular breeding as well as through crop management, such as use of appropriate fertilization, growth regulator application and soil amendments.

“…These parameters are associated with biomass production under different climatic conditions, and can compute the partitioning index by comparing the organ growth rates. This function is useful for estimating dry matter allocation if loss of the accumulated biomass is negligible [14].Fiber strength, length, fineness, elasticity, short fiber index, uniformity index, spinning consistency color grade, and reflectance are fiber quality indicators [15]. These characteristics are negatively affected by genetic factors as well as environmental factors and poor management practices during flowering and the boll formation stage [3,16].…”

High input costs combined with multiple management and material inputs have threatened cotton productivity. We hypothesize that this problem can be addressed by a single fertilization at flowering with late sowing in a moderately populated plant stand. Field experiments were conducted to evaluate the cotton biomass accumulation, phosphorus dynamics, and fiber quality under three planting densities (low, 3 × 10 4 ; moderate, 6 × 10 4 ; and dense, 9 × 10 4 ha −1 ) and two cultivars (Zhongmian-16 and J-4B). High planting density had 6.2 and 12.6% larger stems and fruiting nodes m −2 , while low density produced a 37.5 and 59.4% maximum height node ratio. Moderate density produced 26.4-15.5%, 24.7-12.6%, and 10.5-13.6% higher biomass accumulation rate at the peak bloom, boll set, and plant removal stages over low and high density in both years, respectively. J-4B produced a higher reproductive organs biomass yield when compared with Zhongmian-16 in both years. This higher biomass formation was due to both the higher average (0.8 V T kg·ha −1 ·d −1 ) and maximum (1.0 V M kg·ha −1 ·d −1 ) reproductive organ phosphorus uptake, respectively. Plants with low density had 5.3-18.5%, 9.5-15%, and 7.8-12.8% greater length, strength, and micronaire values over moderate and dense plants, respectively. Conclusively, moderate density with J-4B is a promising option for improved biomass, phosphorus acquisition, and fiber quality under a short season.Agronomy 2019, 9, 500 2 of 18 nitrogen [6], water availability [7], planting date, and planting density [8] are factors that induce changes in dry matter formation and affect reproductive organ biomass accumulation.Biomass distribution in cotton organs during the crop cycle are important determinants of final yield. In the early phases of cotton growth, greater partitioning of foliar tissues enables access to light, which promotes better establishment and provides the basis for fiber quantity and quality later in the season. Similarly, during later growth phases, an increase in the assimilate transport to the reproductive structures ensures better crop yield. Planting density coupled with the cultivar are considered the key drivers for cotton production [8,9]. Due to its indeterminate growth habit, a cotton plant may invest heavily in vegetative biomass under optimum growth conditions. An over-investment of the assimilate into the vegetative or reproductive organs in cotton plants could stimulate the abscission of leaves or fruits, respectively [10,11]. The aboveground biomass of a cotton plant at maturity is often less than the total biomass produced as the plant may shed old leaves and young fruits [8]. Remobilization of biomass to reproductive structure may further reduce the total biomass of vegetative organs during late reproductive growth. Assimilate allocation, and thus the growth rate of a plant organ, is controlled by various environmental and physiological factors [12]. Generally, dry biomass formation and partitioning into organs is measured primarily during certain phenolog...

“…Both LAI and yield increases slowly with an increase in plant density [22]. Fiber quality indicators including fiber strength, fitness, length, uniformity index, and fineness are negatively affected by environmental and genetic factors as well as poor management practices at flowering and boll formation stages [23,24]. Similarly, fiber quality is affected by plant density, irrigation, fertilization, and weather changes [23,25].…”

Comparative Yield, Fiber Quality and Dry Matter Production of Cotton Planted at Various Densities under Equidistant Row Arrangement

et al. 2020

The number of cotton plants grown per unit area has recently gained attention due to technology expense, high input, and seed cost. Yield consistency across a series of plant populations is an attractive cost-saving option. Field experiments were conducted to compare biomass accumulation, fiber quality, leaf area index, yield and yield components of cotton planted at various densities (D1, 1.5; D2, 3.3; D3, 5.1; D4, 6.9; D5, 8.7; and D6, 10.5 plants m−2). High planting density (D5) produced 21% and 28% more lint yield as compared to low planting density (D1) during both years, respectively. The highest seed cotton yield (4662 kg/ha) and lint yield (1763 kg/ha) were produced by high plant density (D5) while the further increase in the plant population (D6) decreased the yield. The increase in yield of D5 was due to more biomass accumulation in reproductive organs as compared to other treatments. The highest average (19.2 VA gm m−2 d−1) and maximum (21.8 VM gm m−2 d−1) rates of biomass were accumulated in reproductive structures. High boll load per leaf area and leaf area index were observed in high planting density as compared to low, while high dry matter partitioning was recorded in the lowest planting density as compared to other treatments. Plants with low density had 5% greater fiber length as compared to the highest plant density, while the fiber strength and micronaire value were 10% and 15% greater than the lowest plant density. Conclusively, plant density of 8.7 plants m−2 is a promising option for enhanced yield, biomass, and uniform fiber quality of cotton.
