Assessment of Water Status and Its Critical Stages in Dryland Barley Genotypes (Hordeum vulgare) Using Crop Water Stress Index (CWSI)

V. Feiziasl

Volume 36, Issue 2 , May and June 2022, , Pages 197-213

https://doi.org/10.22067/jsw.2022.75527.1146

Abstract
  Introduction Barley could be grown under low-input and harsh conditions because of its wide adaptability to drought, and heat stresses. Nonetheless, the water stress leads to yield reduction when drought stress occurs during stem elongation and grain filling stages. In rainfed areas, water and heat ...  Read More

Evaluation of Canopy Nitrogen in Dryland Wheat using ETM+ Satellite Images in South of West Azerbaijan Province

Mirhassan Rasoulsiadaghiani; Vali Feiziasl; Ebrahim Sepehr; Mehdi Rahmati; Salman Mirzaee

Volume 33, Issue 5 , November and December 2020, , Pages 739-749

https://doi.org/10.22067/jsw.v33i5.78811

Abstract
  Introduction: In cereal crops, nitrogen is the most important element for maintaining growth status and enhancing grain yield. Nitrogen is an important constituent of the chlorophyll molecule and the carbon-fixing enzyme ribulose-1, 5-bis-phosphate carboxylase/oxygenase. Therefore, providing enough nitrogen ...  Read More

Evaluation of Soil Fertility Status in Northwest of Iran drylands by Nutrient Index Value (NIV)

V. Feiziasl

Volume 34, Issue 4 , September and October 2020, , Pages 897-919

https://doi.org/10.22067/jsw.v34i4.84165

Abstract
  Introduction Dryland farming is a major agricultural practice in northwest of Iran. Knowledge of soil fertility status in this areas is one of the basic needs of dryland agricultural system. Soil chemical properties play important role for the soil fertility and determined after soil testing. The measurement ...  Read More

Changes in Physical Properties of Soils after Five Years of Application of Conventional and Conservation Tillage Practices

Mehdi Kousehlou; Mehdi Rahmati; Iraj Eskandari; Vali Feiziasl

Volume 33, Issue 3 , July and August 2019, , Pages 477-478

https://doi.org/10.22067/jsw.v0i0.76818

Abstract
  Introduction: Soil is one of the nonrenewable resources (in human being life time scale) that is important to be protected. Tillage operations are carried out in a variety of ways, which in general can be divided into two comprehensive classes of conventional and conservation tillage practices. The tillage ...  Read More

Evaluation of Dryland Barley (Hordum vulgare) Genotypes Response to the Nitrogen Rates and Application Times

vali feiziasl

Volume 31, Issue 2 , May and June 2017, , Pages 490-508

https://doi.org/10.22067/jsw.v31i2.53350

Abstract
  Introduction: Nitrogen is the main component of fertilizer programs necessary for production of high quantity dryland barley. This element is the second limiting factor, after water in dryland areas. So for economic production of barley, the proper nitrogen fertilizer application is essential to increase ...  Read More

Calibration of Soil Available Nitrogen and Water Content with Grain Yield of Dry land Wheat

V. Feiziasl; A. Fotovat; A. Astaraei; A. Lakzian; M.A. Mousavi Shalmani; A. Khorasani

Volume 30, Issue 5 , November and December 2016, , Pages 1556-1573

https://doi.org/10.22067/jsw.v0i0.36954

Abstract
  Introduction: Nitrogen (N) is one of the most important growth-limiting nutrients for dryland wheat. Mineral nitrogen or ammonium (NH4+) and nitrate (NO3−) are two common forms of inorganic nitrogen that can serve as limiting factors for plant growth. Nitrogen fertilization in dryland area can increase ...  Read More

Volume 28, Issue 4 , September and October 2013, , Pages 804-817

https://doi.org/10.22067/jsw.v0i0.29119

Abstract
  In order to determination of water stress threshold and dryland wheat genotypes water status in different nitrogen managements, this experiment was carried out in split split plot RCBD design in three replications in 2010-2011 cropping year. Treatments included: N application time (whole fertilization ...  Read More

Comparison of different methods for determining the Zn critical level of dryland wheat in the Northwest of Iran

V. Feiziasl

Volume 22, Issue 2 , May and June 2008

https://doi.org/10.22067/jsw.v0i22.1011

Abstract
  Abstract In order to determine the critical level and classify the soil Zn in Western Azerbaijan, Eastern Azerbaijan, Kurdistan and Kermanshah dryland areas, a study was conducted in a complete randomized block design having 4 treatments (0, 5, 10 and 15 kg.ha-1 of zinc sulfate) with three replications ...  Read More
