“…Seed cotton yield in the latest planting at the highest plant density was significantly higher than the lowest plant density, as evident in Table 3. Similar results have been found by other researchers (Jones and Wells, 1998;Siebert et al, 2006;Wrather et al, 2008).…”

Cotton growers face a problem of low cotton yield in late planting (after sunflower and maize). The objective of our study was to determine the effects of planting date, plant spacing (plant density), and genotypes on seed cotton yield and its components, ginning outturn (GOT%), and fiber quality traits (fiber length and fiber fineness). Five planting dates (May 1, May 15, May 30, June 15, and June 30), three plant spacings (15, 30, and 45 cm), and three cotton genotypes (CRS-6070, CRS-738, and CIM-496) were evaluated for seed cotton yield with its components and fiber quality traits. The results showed that monopodial branches/plant, sympodial branches/plant, number of bolls/plant, and seed cotton yield differed significantly among different planting dates, plant spacing, and genotypes. While the boll weight was significantly different among genotypes only. GOT%, fiber length, and fiber fineness were different significantly among planting time and cotton genotypes, which were not significantly affected by plant spacing. Cotton grown in early planting dates had higher seed cotton yield (4874 and 4653 kg/hm 2 ) at the highest plant spacing (45 cm). While late sown cotton (June 15 onward) gave higher seed cotton yields (2068 and 1889 kg/hm 2 ) at the lowest plant spacing (15 cm). GOT%, fiber length, and fiber fineness improved significantly in late planting and not affected from plant spacing. From our present study, it is concluded that high seed cotton yield can be achieved at high plant spacing in early planting while at low plant spacing in late planting.

“…It is affected by both crop and soil management factors. Corn produces taller plants at high plant population (Jonathan, et al, 2006). Soil moisture availability (Hussain et al, 1999), soil compaction, surface soil structure, and soil aggregation (Kladivko et al, 1986), fertilizer applications (Kapusta et al, 1996), and tillage system (Kladivko et al, 1986) also influence plant height of corn.…”

Relationship of corn (Zea mays L.) yield with plant height measured during early-to mid-season may possess the potential to be used to develop algorithms for guiding variable-rate N applications within a field. This study evaluated the performance of the linear, quadratic, square root, logarithmic, and exponential models in assessing the relationship of corn yield with plant height measured at three growth stages and four cropping systems for three years. The determination coefficient (R 2 ) values of these five models were generally similar at each growth stage within each cropping system and year or within each cropping system on the three-year combined data. Our results suggest that all these models could be used to describe the relationship of corn yield with plant height during early-to mid-season under different cropping systems and weather conditions, but the linear model may be the preferred model because of its simplicity.

“…O'Berry et al [10] reported that cotton yields were highest with plant populations of 8.9 and 12. McCarty et al [11] reported that plant spacing of 8,15,23, and 30 cm resulted in similar yields in 2003, but yields were significantly affected by plant spacing in 2004. Pettigrew et al [12] in a study with obsolete and modern cotton genotypes grown at densities of five plants m −2 and 10 plants m −2 reported there was no difference in yield between the two densities.…”

The number of cotton (Gossypium hirsutum L.) plants being grown per unit of land area has gained attention due to the technology fees associated with seed containing value added traits. We investigated boll retention, yield, and yield components of cotton grown with reduced stands of 20% to 40% from the uniform planting pattern of four seeds per 30.5 cm of row. Five field experiments were conducted from 2012-2014 using eight treatments arranged in a randomized complete design with six replications. Yield and yield component data were collected. The plant one-row skip one-row treatment resulted in significant yield losses across all five experiments compared to the uniform planting pattern. Treatments with 20% stand reductions did not result in lower total yields; however, each plant in these treatments had to produce two additional bolls to maintain yield. Treatments which had at least 61 cm skips, 40% stand reduction, resulted in lower yields. Treatments had minor affects on boll weight, and lint percentage. The uniform planting pattern produced 67% of its yield from position one bolls compared to about 50% for treatments with reduced stands. Reduced stand treatments produced about 20% of their yield on monopodial branches compared to 10% for the uniform treatment. With modern precision planting equipments, opportunities exist to reduce seed rate and maintain yield; however, many production risk factors must also be considered before a reduced seeding rate is adopted.
