The impact of the combined effects of heat stress, increased vapor pressure deficit (VPD) and water deficit on the physiology of major crops needs to be better understood to help identifying the expected negative consequences of climate change and heat waves on global agricultural productivity. To address this issue, rice, wheat, and maize plants were grown under control temperature (CT, 25°C, ...

A decrease in water resources around the globe in irrigated agriculture has resulted in a steep decline in irrigation water availability. Therefore, management options for efficient use of available irrigation water are inevitable. Deciding the critical time, frequency and amount of irrigation are compulsory to achieve higher crop outputs. Hence, this two-year field study was conducted to asses...

ABSTRACT Water management is an essential concept for water intensive crop such as maize dealing with water shortage under drought conditions. Maize production is ranked after wheat and barely in Fars province, Iran. Therefore, the present study was conducted to investigate the effects of planting methods by conventional and modified planters on maize growth and yield at different irrigation re...

A field experiment was carried out during 2009-11 on a sandy loam soil of IARI, New Delhi on wheat with four levels of irrigation (rainfed, irrigations to replenish 30, 60 and 100% moisture deficit from field capacity) as main plot factors and four levels of nitrogen (0, 30, 60 and 120 kg N/ha) as subplot factors in a split plot design. The soil moisture storage in the profile showed inverse re...

In according with wheat ecophysiological characteristics, the author applied technologies of system engineering method, crop simulation and computer to build wheat developing process cooperative models including growth model, developmental phase models, water balance model and nitrogen balance model etc. with the support of basic data such as variety characteristics, weather data, soil level an...

in order to evaluate the effects of sub soiling and irrigation level treatments on yield of sugar beet and wheat in rotation, an experiment was conducted at agricultural research station ofwest azerbaijanprovince. the plots were arranged as a strip plot experiment in randomized complete block design with three replications. horizontal plot (sub soiling treatment) consisted of sub soiling depth ...

in order to investigate the effect of hexaconazole (hex) on the increasing tolerance to water deficit stress of two soybean (glycine max l.) cultivars, an experiment was conducted in faculty of agronomy of tarbiat modares university as factorial experiment in randomized complete block design arrangement. factors examined in this study were included soybean cultivars (l17 and clark63), hex conce...
