“…In this study, LP values were high, as compared with other studies carried out in similar environments [6,7]. In these cases plants were planted at 62,500 pl ha −1 and followed the same pattern as reported by McCarty et al [31], where LP become higher as plant population increased. Zhi et al [29] reported an increase of 3.1% in LP in plants at 87,000 pl ha −1 compare with plants at 15,000 pl ha −1 .…”

Evaluation of sowing density is an important factor for achieving maximum yields without affecting other agronomic traits. Field experiments were conducted during three consecutive years (2008, 2009 and 2010) to determinate the effect of four sowing density (62,500; 83,333; 100,000 and 142,857 pl ha−1) on yields and its components of two cotton varieties, ‘Delta Pine 16′ and ‘SN-290′ in Venezuela. The traits evaluated were lint yield, boll weight, number of seeds per boll, 100-seed weight, and fiber content. Highly significant differences (p ≤ 0.01) were observed among genotypes, sowing density and their interactions for all traits. Sowing density was not affected by year factor. High lint yield was found in ‘SN-290′ (4216.2 kg ha−1) at 100,000 pl ha−1; and in ‘Delta Pine 16′ (3917.3 kg ha−1) at 83,333 pl ha−1. The highest sowing density (142,857 pl ha−1), decrease lint yield and yield components in the genotypes. The highest boll weight was obtained by ‘SN-290′ with 6.4 g in average. All sowing densities evaluated resulted in lint percentages above 40%. Cotton lint yield was positively correlated with all yield components. Our results indicate that highest lint yields could be obtained with sowing densities between 83,333 and 100,000 pl ha−1 depending upon varieties used across savannahs of Venezuela.

“…The highest average boll weight value was observed at plant density S4 (28,531 plants/da) with 3.9 g and the lowest boll weight value was observed at plant density S5 with 3.1 g (Figure 2D). The findings of the study were different from the results of Fowler and Ray (1977), Kaynak (1995), Jones and Wells (1998), Bednarz et al (2000), Akhtar et al (2002), McCarty et al (2017 who reported that boll weight decreased with increasing plant density.…”

This study investigates the impact of varying planting densities on cotton plants’ morphological traits and yield. As planting density increases, there is a reduction in monopodial and sympodial branches, resulting in a more compact plant structure. The study highlights the highest yield achieved with specific planting densities, endorsing the viability of both holl and row planting methods. It suggests adopting narrow or ultra-narrow row systems to enhance yield and economize input costs. The study was conducted in 2017 at the experimental field of Aydın Adnan Menderes University in the Faculty of Agriculture’s Department of Field Crops. The material used in this study was the widely cultivated cotton variety “Gloria” in the Aegean region. The investigation was conducted using a randomized block design with 4 replications. In evaluating cotton yield and related parameters, it was observed that D1 and D2 (14.285 plants/da) achieved the highest yield concerning plant density, emphasizing the viability of both holl and row planting methods. The study concluded that augmenting the number of plants within a specific area of production significantly contributes to higher seed cotton yields. To enhance yield and economize cotton input costs, the adoption of a narrow or ultra-narrow row production system is suggested as an alternative strategy to conventional methods.

“…In contrast to monopodial bolls plant −1 , there were no differences in the number of monopodial bolls ha −1 between each of the row spacings, with a range of 83,680 monopodial bolls ha −1 in the 91‐cm row spacing and 92,900 monopodial bolls ha −1 in the 183‐cm row spacing (Figure 5b). The expectation of more monopodial bolls in wider row spacings was accurate with the 183‐cm row spacing on a plant −1 basis (McCarty et al., 2011). However, there were no differences in monopodial bolls when observed on a hectare basis.…”

This study quantifies the effects of wide row spacing on lint yield, yield components, and fiber quality of upland cotton (Gossypium hirsutum L.). An experiment was conducted in Tifton, GA in 2021 and 2022, where cotton was planted in six replications of 91‐, 122‐, 152‐, and 183‐cm row spacings. Following defoliation, 1.8 m was hand harvested from each plot, and boll density plant−1 and density ha−1 were determined for sympodial and monopodial branches. Additional measurements included fruit and lint yield distribution assessments and intra‐boll yield components including seed cotton weight boll−1, seed index, seed boll−1, lint weight seed−1, seed surface area (SSA), fiber density, and single fiber weight. Lint yield was reduced 20% in the 183‐cm row spacing compared to the 91‐cm row spacing. The 91‐cm rows had the lowest number of sympodial bolls plant−1 with 152‐ and 183‐cm rows demonstrating a 24%–28% increase in sympodial bolls plant−1. Sympodial bolls ha−1 were reduced 22% in the 183‐cm row spacing compared to the 91‐cm row spacing. There were no differences in bolls ha−1 or lint yield ha−1 with respect to monopodial growth. There were no differences in seed cotton weight boll−1, seeds boll−1, fiber density, single fiber weight, or turnout. Seed index and SSA were increased in the 183‐cm row spacing. Lint weight seed−1 was reduced in the 91‐cm row spacing.
