An Integrated Approach for Nitrogen Management in Upland Cotton Production
… since N is the most applied nutrient in U.S. cotton production. Despite this, N uptake and use efficiency (NUE) in cotton remains below 50%, which presents challenges of environmental quality. Studies were conducted across 4 states in the US Cotton Belt with the overall objective of evaluating …

Tillage System Effects On Upland Cotton Yield and Development In Virginia
… which provides the best agronomic benefits for cotton production in the coastal plain soils of Virginia was the basis for this research. Strip-tillage was evaluated from 2015-2016 on-farm to determine the effects of annual and biennial treatments on plant growth and lint yield, as well as …

Investigating Nutrient Management Innovations in Upland Cotton Production to Increase Agronomic Efficiency
… was focused on increasing the efficiency of upland cotton production in the northern cotton belt through the use of new fertilizer formulations, placement, and timings. The objectives of the experiments reported in this thesis were to: 1) evaluate the effects of side-dress potassium (K), …

Inheritance of fiber length mutants of upland cotton and relationships among lint yield, fiber quality, and economic indices
The narrow germplasm base of upland cotton iGossypium hirsutum L.) varieties grown on the Texas High Plains has historically been limited by relatively poor fiber quality. Prior work at Texas Tech University identified two chemically induced mutants (TTU 202 and TTU 271) that appeared to carry at …

Quantitative trait loci mapping for agronomic and fiber quality traits in Upland cotton (Gossypium hirsutum L.) using molecular markers
The breeding of Upland cotton (Gossypium hirsutum L.) cultivars that combine high yield and fiber quality is a major challenge to the breeder. The understanding of the quantitative trait loci (QTL) contributing to agronomic and fiber quality traits offers an excellent route to solve this problem. A …

Comportamento do algodoeiro herbáceo BRS Araripe em diferentes lâminas de irrigação no Cariri Cearense
… aimed to evaluate the growth, the behavior of upland cotton BRS Araripe in different irrigation levels. The study was conducted at the Experimental Station of Cotton Embrapa, Barbalha, CE, Brazil, from July to December 2010. The experimental plot was a randomized block delineament with four …

Development of Computational Tools and Resources for Cotton microRNA Analysis
… almost all biological and metabolic processes. Upland cotton (Gossypium hirsutum L.), one of the most important fiber producing crops, is widely planted in the world. Upland cotton originated from the reunion of two ancestral cotton genomes (A and D genomes) approximately 1-2 Myr ago, owning a …

US yield forecasting using crop condition ratings
… grown in the United States, corn, soybeans, upland cotton, winter wheat, and spring wheat, and crop condition ratings from 1986 to 2015. Three statistical models were tested, the first one including all categories of condition ratings, a trend, and no intercept. The second model addresses the …

Evaluating Commodity Farm Program Selection and Economic Return Variability on Representative Farms in the Mississippi River Delta Region Using a Risk Return Framework
… rice and soybean farms and six corn, cotton, and soybean farms were modeled as to determine the five year net returns resulting from price and yield risk as well as to evaluate alternative farm program and crop insurance selection. Financial performance of these farms is measured for …

Purple nutsedge (Cyperus rotundus L.) competition with cotton: Species biology and effects of proportion, density, and moisture
… competition between purple nutsedge and upland cotton. Purple nutsedge produced more total dry weight than cotton in wet conditions but produced less or similar total dry weight in dry conditions. Cotton's ability to extract water from greater soil depth and maintain a high rate of …

Evaluation of Cover Crops, Conservation Tillage, and Nitrogen Management in Cotton Production in Southeastern Virginia
The response of upland cotton (Gossypium hirsutum L.) to legume and small grain cover crop establishment, in-season nitrogen (N) rate, and fertilizer N placement was investigated in two experiments located in coastal plain Virginia and North Carolina. The first experiment examined 1) soil …

Evaluation of rotation varieties strategies to control reniform nematode in cotton (Gossypium hirsutum L.)
… of the most important pathogens associated with cotton (Gossypium hirsutum L.) yield losses in Texas. In the United States, currently 17 states are producers of cotton (Gossypium spp.), with Texas being the main producer. Approximately 60 % of the total production in the United States is produced …

The Cloning and Characterization of Two ROP/RAC G-Proteins from Gossypium Hirsutum
… in plant development. Until recently, only three cotton (Gossypium hirsutum) Rop/Rac G-protein genes were sequenced, representing subfamilies III and IV of the plant monomeric Gprotein family. In this project, members of subfamilies II and I were cloned, sequenced, and named GhRac2 and GhRac3, …
