Lint Yield of Four Seed Qualities of Stoneville 825 Upland Cotton Planted at 3 Locations, 3 on Planting Dates and at 3 Planting Rates in Arizona in 1986Kittock, D. L., Hofmann, W. C. 03 1900 (has links)
Low quality Stoneville 825 seed produced reduced stands and, in most cases, reduced lint yields when planted at 3 dates and 3 planting dates at 3 locations in Arizona. Reduced lint yields were explained by reduced stands. Highest lint yield was obtained from the second plantings, 24 and 21 April at Marana and Safford, respectively.

Effect of Calcium Nitrate and Calcium Chloride on the Primary Root Growth of Cotton Seed Imbibed at Low TemperaturesLehle, Fredric, Hofmann, W. C., Guhy, Bonnie 03 1900 (has links)
The effect of various concentrations of calcium nitrate and calcium chloride on the primary root (radicle) growth of cotton seed at a suboptimal temperature was evaluated 14 days after imbibition onset under laboratory conditions. Both forms of calcium at concentrations up to 10 mM enhanced cotton seed radicle growth at 15 C.

Direct and Indirect Stimulation of Primary Root Growth of Cotton Seed Imbibed at a Low Temperature by Calcium SulfateLehle, Fredric, Hofmann, W. C., Guhy, Bonnie 03 1900 (has links)
The effect of calcium sulfate on cotton seed radicle growth at a low temperature was evaluated under laboratory conditions. Direct imbibition of solutions of calcium sulfate was stimulatory to radicle growth at 15 C at concentrations up to 10 mM. Anomalous stimulation of radicle growth at 15 C occurred when seed rolls moistened with water were placed adjacent to dilute open solutions of calcium and magnesium sulfate inside sealed chambers. The stimulation appeared due to an indirect influence of sulfate by an unknown mechanism.

Narrow Row Cotton Evaluation, Marana Agricultural CenterThacker, Gary W. 03 1900 (has links)
In a preliminary, unreplicated test, cotton was planted in 40 inch and 27 inch rows on April 10 and again on May 1. Narrow rows outyielded 40 inch rows at both planting dates. The yield difference between the row spacing treatments was greatest in the May 1 planting. Both row spacings had higher yields when planted on the later date, as did both the DPL 90 and ST506 varieties used in the test.

Selecting for Cotton Seedlings Under Cool and Saline ConditionsHofmann, W. C., Else, P. T. 03 1900 (has links)
A breeding program aimed at increasing the ability of long and short staple cotton strains to emerge in saline soils under cool springtime soil conditions has now completed the second cycle of selection. Cycle II emergence results show evidence of progress.
