Impacts of Drought Stress and Planting Methods on Sweet Corn Yield and Water Use Efficiency
Abstract Seasonal drought is the most important factor to limit the production of maize in the world. Using a split plot design, a two year field experiment was conducted to determine the effect of limited irrigation regime on yield, yield components and water use efficiency of sweet corn (Zea mays var. saccharata). Responses of three sweet corn varieties KSC403, Merit and Obsession to three di...
متن کاملEngineering crassulacean acid metabolism to improve water-use efficiency.
Climatic extremes threaten agricultural sustainability worldwide. One approach to increase plant water-use efficiency (WUE) is to introduce crassulacean acid metabolism (CAM) into C3 crops. Such a task requires comprehensive systems-level understanding of the enzymatic and regulatory pathways underpinning this temporal CO2 pump. Here we review the progress that has been made in achieving this g...
متن کاملGeospatial Technologies to Improve Urban Energy Efficiency
The HEAT (Home Energy Assessment Technologies) pilot project is a FREE Geoweb mapping service, designed to empower the urban energy efficiency movement by allowing residents to visualize the amount and location of waste heat leaving their homes and communities as easily as clicking on their house in Google Maps. HEAT incorporates Geospatial solutions for residential waste heat monitoring using ...
متن کاملMaize response to water, salinity and nitrogen levels: yield-water relation, water-use efficiency and water uptake reduction function
Water, salinity and nitrogen are the major factors affecting maize production in arid and semi-arid areas. The objectives of this study were to investigate the effects of different water, salinity and nitrogen levels on yield-water relationships, water use, water productivity (WP), water use efficiency (WUE) and water uptake reduction function by maize hybrid SC-704 in a semi-arid area and ...
متن کاملEffect of Planting Date and Sowing Methods on Ear Yield, Water Use Efficiency and Some Physiological Characteristics of Sweet Corn
In order to investigate the effect of planting date and sowing method on ear yield, water use efficiency and some physiological characteristics of sweet corn, an experiment was carried out as a split plot based on a randomized complete block design with three replications in Yasouj, south-west of Iran. Planting date consisted of five levels (4 May, 19 May, 4 June, 19 June, 5 July) and considere...
