Estimation of base temperature in different growth stages wheat Case study: Sararood Station Kermanshah
this study was conducted to determine grain yield stability of rainfed promising barley genotypes across six rainfed research stations (maragheh, sararood, uromieh, qamloo, zanjan and ardabil) under cold and semi-cold conditions during three cropping seasons (2006-2009) in iran. the studied genotypes were 10 promising barley lines along with two checks (one local and one newly released variety,...
The goal of this study was to apply artificial neural networks to predict rain-fed wheat yield using meteorological data a few days to few months before harvesting. The climatic observation data used; were mean of daily minimum and maximum temperature, extreme of daily minimum and maximum temperature, sum of daily rainfall, number of rainy days, sum of daily sun hours, mean of daily wind speed,...
Drought is one of the phenomena that has recently been identified as a major challenge , and has incurred a lot of damage in different parts of the world. The purpose of this study was to investigate and map drought in Kermanshah Province using the CZI index in ArcGIS for 1995-2016 using data from synoptic stations of Kermanshah, Kangavar, Sahneh, Harsin, Mahidshah, Sararood, Paveh, Ravansar, S...
Iskander Aliev A sharp lower bound for the Frobenius number Ferdinand Georg Frobenius (1849–1917) raised the following problem: given N positive integers a1, . . . , aN with gcd(a1, . . . , aN ) = 1, find the largest natural number gN = gN (a1, . . . , aN) (called the Frobenius
In this study, in order to study the base temperature (minimum temperature for plant growth) at the degree of growth day (GDD), which is one of the important parameters in calculating the degree of growth day, first, the data required for the 2009-2017 statistical period of wheat production at the station Sararood was taken from the station. Then, after sorting and separating growth different s...
in this study, application ofweap model (soil moisture method) have been investigated for simulating hydrological behavior in ahar-chai basin. according to the development of pressurized irrigation systems in this basin, since 2005, two models were carried out for two periods, pre-pressurized period (1998-2006) and pressurized period (2006-2013). irrigation method in first model was surface irr...
The Present study was Include some physical and chemical characteristics for east southern AL-Hammar marsh south of Iraq during November 2006 to 2007 .The Samples were collected on monthly two stations, first AL-Nagarah second ALBurgah, change temperature. highest temperature value in august 30mºand 25mº station respectively, wheel lowest February 11mº January 10mº station. salinity Ogest 2 par...
introduction climate change generally affect all economic sectors, but the agricultural sector is the most sensitive and vulnerable sector, because crops are highly dependent on climatic resource. according to the scientific evidences, climate change in the future, especially the combined effects of rising temperatures and rising co2 concentrations in the atmosphere and increase the likelihood ...
