this study was conducted in order to sustainable conservation and utilization of trifolium genetic resources. a total of 1333 accessions of trifolium under 32 species from 27 provinces were collected according to ipgri descriptors. collected germplasms are conserved in mid- and long-term conservation at national plant gene bank of iran. statistical parameters of tendency to center and dispersio...

This study set out to analyses rice total factor productivity in Nigeria ecological zones and the growth trend from 1996 to 2010. Statistical information on domestic and imported quantities of rice was obtained for 15 years (1996 to 2010) from the AGROSTAT system of the statistical division of the Food and Agriculture Organization (FAO), Federal Ministry of Agriculture statistical bulletins, Ce...

The purpose of this study is to investigate the role of oil, natural gas and coal consumption in Iran’s economic growth during the periods from 1980 to 2012. The stationary analysis is performed by using ADF and Phillips-Perron unit root test and Auto-Regressive Distributed Lag (ARDL) approach was used to test for co-integration between the variables. The findings show that the variables are co...

Total factor productivity (TFP) has emerged as an important source of agriculture growth. However, this area remained neglected by researchers as well as policy makers in Pakistan. The studies which have estimated agriculture TFP growth in Pakistan are very few and they have tended to overstate it by ignoring the variation in capacity utilization, hours worked and improvement in labour producti...

the aim of this paper is to study the impacts of technological progress and efficiency change on the productivity growth of iran agriculture separated by provinces. the period of this study is from 2005-2014. first of all, the impacts of efficiency change and technology change were separated using dea and malmquist model. then, their impacts on productivity growth were studied. it was concluded...

In the light of previous literature fertility determines different economic, social and program inputs variables. The main object of this study to investigate the impact of sector specific (health and education) foreign aid on fertility in case of Pakistan. For empirical investigation Auto Regressive Distributed Lag Model (ARDL) is used over the period of 1973-2012. The results of the study sho...

This study employs auto-regressive distributed lag (ARDL) bounds approach to cointegration for long run and errorcorrection modeling (ECM) for short run analysis to examine the relationship between revenue gap and economic growth for Pakistan using annual time series data over the period 1980 to 2008. The short and long run results indicate that revenue gap is statistical significant and negati...

This paper empirically investigates the causal relationship between energy prices and economic performance in South Africa by employing auto-regressive distributed lag (ARDL) bounds test technique for period 1994 to 2019. The empirical evidence that was reviewed used a different methodology covered periods, particularly African context. While previous studies investigated examining oil or elect...
