Yield and some agronomic parameters of upland cotton as affected by planting dates

Different sowing dates affected cotton yield and yield components

This study was conducted to determine whether selecting an optimum sowing date couldimprove yield. The experiment consisted of sowing a film-covered, drip-irrigated cotton field onfour sowing dates from April to May in 2011-2012 at the Agrometeorological ExperimentalStation of Wulanwusu, which was in an arid region of north-western China. Late sowing datesproduced less yield and water-use effic...

Growth and Yield of Snap Beans as Affected by Wind Protection and Microclimate Changes due to Shelterbelts and Planting Dates

The effects of wind protection on growth and total and marketahle yields of snap hean tPhaseolus vulgaris L.) planted at 2-week intervals through the 1994 and 1995 growing seasons were examined. Research was conducted under nonirrigated conditions at the Shelterhelt Research Area, Univ, of Nebraska Agricultural Research and Development Center (ARDC) near Mead. 'Strike' <white-seeded) and 'Rushm...

Sunflower summer-planting yield as affected by plant population and nitrogen application rates

Seed yield and some physiological traits of safflower as affected by water deficit stress

Safflower (Carthamustinctorius L.) is an oilseed crop adapted to drought prone arid and semi-arid environments. This study was conducted to evaluate the effects of water deficit stress on antioxidant activity, membrane stability index (MSI), leaf chlorophyll content, leaf area index (LAI) and their relationship with seed yield using 64 safflower genotypes grown under normal and water defici...

Yield and fiber quality of Upland cotton as influenced by nitrogen and potassium nutrition

Nutrient stress in Upland cotton (Gossypium hirsutum L.) depresses lint yield, particularly of late-season fruit (bolls), and may disrupt fiber development. A 2-year (1999 and 2000) study was conducted outdoors in large pots to determine individual effects of nitrogen (N) and potassium (K) stress at flowering stage on lint yield and fiber quality. Treatments were half-strength nutrient solution...
