Summaries Of Arkansas Cotton Research 2021, Fred Bourland

Arkansas Agricultural Experiment Station Research Series

While the basic growth and development of the cotton plant have not changed significantly in recent history, the business of cotton production is ever-changing. The last two years have seen us plant a crop just about as late as we thought possible, yet extended favorable conditions at season's end have been our salvation, helping to lead us to record yields. The economic environment over the last few years has been such that farmers need to produce record or near-record yields to advance. Unfortunately, production levels at the state yield average barely cover out-of-pocket expenses.

Great uncertainties exist for the upcoming …

Improving Water And Plant Growth Regulator (Pgr) Management Practices In Cotton: Cultivar Physiological Responses And Pgr Rates, Kurt Wedegaertner

Masters Theses

Cotton (Gossypium hirsutum L.) is grown in an increasingly unpredictable climate and often under rainfed conditions. Without irrigation to alleviate common drought conditions, cultivar selection becomes a primary tool in mitigating the negative effects of water-deficit stress. Cultivars can differ in water use under water-limited environments, which can affect crop performance. Moreover, cotton management must involve balancing vegetative and reproductive growth through the use of plant growth regulators (PGR) due to the plant’s perennial growth pattern. The efficacy of PGRs are dependent on many variables including environmental conditions, irrigation, and genetics (cultivar). In 2020 and 2021, a series of …

Effect Of Sowing Date And Topping Process On Some Morphological And Productivity Traits Of Cotton Under A Zone Condition In Al Hasaka Governorate/ Syria, تأثير موعد الزراعة وعملية التطويش في بعض الصفات الشكلية والإنتاجية لمحصول القطن في ظروف منطقة الاستقرار الأولى لمحافظة الحسكة/سورية, Momena Rakkad

This research was carried out during growing season 2014 in Tel Half village (AL Hasaka governorate/Syria) In order to study the effect of sowing date and topping process on some morphological and productivity Traits of cotton (Var. Halab-90 ), planting were applied in tow dates, the first of date planting took place in 19/4/2014, and the second in 5/5/2014.and applying three methods of topping main stem topping, fruit shoots topping, total topping (main stem topping and fruit shoots topping) in addition to control treatment (without topping), The experiment was design according to spilt plot design with three replication, where main …

Arkansas Cotton Variety Test 2021, F. Bourland, A. Beach, B. Milano, C. Kennedy, L. Martin, B. Robertson

Arkansas Agricultural Experiment Station Research Series

The primary goal of the Arkansas Cotton Variety Test is to provide unbiased data regarding the agronomic performance of cotton varieties and advanced breeding lines in the major cotton-growing areas of Arkansas. This information helps seed companies establish marketing strategies and assists producers in choosing varieties to plant. These annual evaluations will then facilitate the inclusion of new, improved genetic material in Arkansas cotton production. Adaptation of varieties is determined by evaluating the lines at five University of Arkansas System Division of Agriculture research sites (Manila, Keiser, Judd Hill, Marianna, and Rohwer). The 2021 tests at Rohwer were abandoned due …
