Sep 12, 2018
ABSTRACT A four year field test was initiated in 1997 to evaluate potassium as a soil treatment on yield and fiber quality of cotton in Adana. Four rates of potassium as K2SO4 (0, 80, 160 and 240 kg/ha) were applied to C.1518 cotton in two splits with half the K applied at planting and half when the crop reached the first bloom stage. Yield, plant...

Sep 12, 2018
ABSTRACT The supply of nutrients through the soil can be restricted by different factors such as soil compactness, extreme conditions of soil/water regime, pH of the soil solution, etc. Excessive N application to the soil might lead to environmental hazards. Foliar fertilization, when correctly applied provides solutions to many of these cases and...

Sep 12, 2018
ABSTRACT In areas of the USA where cotton (Gossypium hirsutum L.) is traditionally harvested with a spindle picker, there is widespread interest in producing cotton in narrow rows and harvesting with a stripper harvester. Optimum management practices with this system are not well-defined. This study was conducted to determine the effects of residu...

on
Sep 12, 2018
ABSTRACT Studies across the cotton (Gossypium hirsutum L.) growing regions of the United States have shown boron and nitrogen to be essential nutrients for profitable cotton production. Four levels of nitrogen (N) (0, 34, 67, and 101 kg/ha for 1996 and 0, 67, 101, and 135 kg/ha for 1997) and four levels of boron (B) (0, 0.56, 1.12, and 2.24 kg/ha)...
Assessing the Salinity Threat to Sustainable Irrigated Cotton Production in the Lower Gwydir and Macintyre Valleys
By
Muhammad Naveed Arshad
on
Sep 12, 2018
ABSTRACT Worldwide, the incidence of soil and water salinisation is increasing. This is particularly the case in irrigated agricultural regions and potentially in Australia’s intensively irrigated cotton-growing areas. This paper describes a broad scale approach to estimate this threat in the cotton growing areas of the lower Gwydir and Macintyre...

on
Sep 12, 2018
ABSTRACT The optimal management of irrigation is a principal constraint facing agriculture worldwide. The potential number of combinations of irrigation schedules over a growing season is enormous when the variables involved are considered. Theoretically, on any given day during a cropping season, a decision can be made to irrigate or not. This as...

on
Sep 12, 2018
ABSTRACT The effects of irrigation timing and plant density on the main morphological and agronomic characters of cotton were investigated over five years from 1987 to 1991 in Southern Italy. Five irrigation levels were combined with four plant densities (6, 9, 12 and 15 plants per m2). Times and volumes of irrigation were determined by thermopluv...

on
Sep 12, 2018
ABSTRACT An experiment was conducted on G. hirsutum variety LRA 5166 under summer irrigated conditions in Western Maharashtra to assess the possibility of reducing rates of N fertilizer through the use of bio-fertilizers. The experiment was on a medium deep, black soil, low in N, medium in P2O5 and high in K2O. Experiments were repeated over three...

Sep 12, 2018
ABSTRACT The influence of temperature, relative humidity, rainfall and irrigation on the duration of cotton phenological stages was studied in the cotton producing zone of Greece during a 10 year period (1986-1994). Influence was found to be parameter and stage dependent. Temperature was the most time affecting parameter. More specifically, the mi...

on
Sep 12, 2018
ABSTRACT Normal cotton management practices in South Texas terminate irrigation as early as first open boll (about 6 weeks after first bloom) and use N fertilization rates ranging from 135 to 200 kg/ha. Experiments were conducted at the Texas A&M University Agricultural Research and Extension Centre in Uvalde, TX during the 1995, 1996, and 199...
