By Muhammad Naveed Arshad on Apr 18, 2019

WCRC WCRC2

ABSTRACT Twenty five percent of the world’s total area is under vertisols and vertic inceptisols exist in India (Rao et al 1997). Over 60% of the cotton produced in India comes from these soils. Hybrid cotton is cultivated in about 3.8 m ha, the majority on vertisols, where cotton is primarily a rainfed monsoon crop (ICAC.1997). Vertisols are clas...

Laboratory Screening Test for Cotton Seed Germination and Emergence Under Low Temperatures
By Muhammad Naveed Arshad on Apr 18, 2019

WCRC WCRC2

ABSTRACT Cotton is a tropical perennial plant that is grown in the U.S. as a temperate annual. Approximately 20% of the U.S. crop is produced in the Texas High Plains, an area characterized by a short growing season in terms of accumulated heat units. Cool spring nights can reduce the germination of seeds and establishment of seedlings. The object...

Physiology of Cotton under Irrigated and Dryland Conditions in Spain
By Muhammad Naveed Arshad on Apr 18, 2019

WCRC WCRC2

ABSTRACT The main cotton-producing area in Spain is Andalucia, where it is grown mainly under irrigation (about 100,000 ha). Efforts are being made to increase the efficiency of irrigation water use. This investigation compares responses of five cultivars of upland cotton to growth under irrigated (Las Torres field station at Alcalá del Rio) or ra...

Physiological Responses of Cotton to Water Deficit in Pakistan
By Muhammad Naveed Arshad on Apr 18, 2019

WCRC WCRC2

ABSTRACT In Pakistan most cotton is grown under irrigation. Between 1994 and 1997 a series of experiments were conducted at two sites, The Postgraduate Agriculture Research Station of the University of Agriculture, Faisalabad and the Central Cotton Research Institute in Multan, to examine the effects of reduced irrigation on the yield and physiolo...

Problems of Growing Cotton in Marginal Regions
By Muhammad Naveed Arshad on Apr 18, 2019

WCRC WCRC2

ABSTRACT Bulgaria is among the most northerly cotton producing countries in the world. Hydrothermal conditions during the growing season put specific requirements on cultivars and production practices. Russia and the Ukraine intend to re-introduce cotton production based on Bulgarian experience and early maturing cultivars. The constraints will...

FINISH®, a Physiological Approach to Cotton Boll Opening and Defoliation
By Muhammad Naveed Arshad on Apr 18, 2019

WCRC WCRC2

ABSTRACT Dehiscence processes (boll opening, leaf shedding) in the cotton plant is mediated through a delicate balance of plant hormones. Ethylene promotes dehiscence primarily by stimulating the enzymes involved in the hydrolysis of insoluble pectates and cellulose that ensure the adherence of cells in the abscission zones. The growth promoting p...
