Irrigation studies provide a framework for evaluating agricultural production and the water resource management in locations where water is scarce. Field experiments were conducted at Barbalha- CE (no...
With increased environmental pressures, cotton producers may need to improve the efficiency of N fertilization. Including foliar applications in a cotton fertility program can improve N efficiency thr...
Two sets of field experiments were conducted during kharif and rabi seasons of 2002-’03 and 2003-’04 at New Delhi under irrigated conditions to formulate site-specific nutrient management strate...
Although the early-planted cotton production system offers the potential of improved lint yield, production techniques need to be optimized to ensure consistent yield enhancement. The objectives of th...
Mepiquat chloride (1,1-dimethyl-piperidinium chloride) is a plant growth regulator that can be used by producers to manage crop development, uniformity, and maturity. Field experiments were conducted ...
In-furrow applications of plant growth regulators (PGRs) and starter fertilizers have been used to improve cotton (Gossypium hirsutum L.) yields. Information about the effects of plant growth regulato...
Ethephon (2-chloroethyl phosphonic acid) may interact with various defoliants in cotton (Gossypium hirsutum L.), because of differences in mode of action or optimal temperatures for activity. Field te...
Expansion of cotton (Gossypium hirsutum L.) production in the Ogallala Aquifer region of the United States can be attributed to early maturing cultivars, rising energy costs, and declining groundwater...
Due to its indeterminate growth habit, maturation of cotton (Gossypium hirsutum L.) is affected by many environmental and cultural factors. An easy and reliable measure of its progression toward matur...
Conservation-tillage practices have renewed interest in research evaluating fertilization responses of cotton. Research was conducted to evaluate the cotton-yield response to P and K fertilization und...
Price discounts associated with inferior cotton (Gossypium hirsutum L.) fiber quality might be avoided through alternative planting strategies involving mixing cultivars of various yield and quality c...
Research to delineate nitrogen, potassium, and mepiquat chloride (MC) effects on cotton performance has been primarily conducted with upland cotton (Gossypium hirsutum L.). A field study was conducted...
Winter annual cover crops could help control soil erosion problems on sloping Piedmont soils in a no-till cotton (Gossypium hirsutum L.) production system. Field experiments were conducted from 1995 t...
Transgenic, herbicide-resistant cotton and recently commercialized equipment to spindle-pick 38-cm rows have renewed interest in narrow-row cotton production. Published research relative to mepiquat c...
Some crop managers are concerned that repeated use of dolomite lime, which contains 10 to 15% Mg, will produce excessively high soil Mg+2 levels relative to Ca+2 and reduce cotton (Gossypium hirsutum ...
