In this regard, an experiment was conducted as a completely randomized design in five treatments and three replications in the Advanced Greenhouse of the Research Institute of Biotechnology, Rasht. The Growing media control of this study, peat-perlite-sand, was considered 1: 1: 1 ratio, and the compost Azolla was replaced by 0%, 25%, 50%, 75% and 100% volumes. The treatments consisted of: Azolla compost + 100% Peat-perlite-sand (control), Azolla compost + 75% Peat-perlite-sand, 50% Azolla compost + 50% Peat-Pearlite-Sand, 75% Azolla compost + 25% Peat-perlite-sand and 100% Azolla compost + 0% Peat-perlite-sand. In this experiment, growth indices, including number of leaves, number of buds, length of bud, fresh and dry weight of stem, fresh and dry weight of root were measured. The results showed that replacing Azolla compost levels had a significant effect on leaves number, length of bud, fresh and dry weight of stem, fresh and dry weight of root. Comparison of the substrate used showed that replacement of 25% Azolla compost in the Growing media had the most effect on Pedilanthus plant growth indices. Manuscript profile -

The main purpose of this study is to investigate the effect of the manufacturing Purchasing Managers Index (PMI) on the stock price index in Iran. Therefore, the present study has used the monthly data from 2018:10 to 2022:11 and using the Granger causality method and Johansen co-integration to investigate the relationship between Purchasing Managers Index and total stock price index and manufacturing stock price index. The results indicate that there is a one-way causality from the growth of the manufacturing purchasing managers index to the growth of the total stock price index and the growth of the manufacturing stock price index. Also, based on Johansen's cointegration test, there is a long-term positive relationship between the growth of manufacturing purchasing managers index and the growth of total stock price index, and also between the growth of manufacturing purchasing managers index and the growth of manufacturing stock price index. Given that the increase in PMI indicates economic prosperity in the manufacturing sector, this positive relationship shows that, as expected, stock price indices react positively to improvement signals in the manufacturing sector and negatively to negative signals.

4 - The effect of financial indicators on economic growth in Islamic countries using a non-linear model
hadi agababei Manijeh Hadinjad S. Khashayar Seyed ShokriAbstract One of the factors that play an essential role in achieving the goal of rapid and continuous economic growth is the development of the financial sector of each country. Countries with a more developed financial system are on the path of faster economic growth MoreAbstract One of the factors that play an essential role in achieving the goal of rapid and continuous economic growth is the development of the financial sector of each country. Countries with a more developed financial system are on the path of faster economic growth because they make the economy in question capable of experiencing higher growth rates. The main purpose of this article is to investigate the effect of financial development indicators on economic growth in member countries of the Islamic Conference; Therefore, in order to examine this topic, the present article used one of the newest econometric approaches called the PSTR model and measured the non-linear effect of financial development indicators on economic growth in the member countries of the Islamic Conference during the period from 2008 to 2022. The results obtained from the PSTR model indicate the existence of a non-linear relationship between the studied variables. In the final PSTR model, the slope parameter, which indicates the speed of adjustment from one regime to another regime, is equal to 21.0818, the location of regime change is estimated to be 10.5986. Therefore, if the financial development index (the ratio of internal credits of banks to gross domestic product) exceeds 10.5986 percent, the behavior of the variables will be according to the second regime, and if it is less than the above threshold, it will be placed in the first regime. The coefficients of the variables (percentages) have been estimated. The obtained results show that the financial development index (the ratio of internal credits of banks to gross domestic production) has a different effect on economic growth in both regimes.

Inflation, in fact, leads to non-optimal resource allocation, economic inefficiency, and disarray in the social, cultural, and political condition of the society. Unemployment, like inflation, causes disarray in the society. Unemployed people appear as parasites in the society and play no part in production and social services. Moreover, unemployment causes people to be trapped in issues such as crime, addiction and moral corruption which leads to the disruption of the society’s cultural texture. Inflation and unemployment are two major social issues. The harmful effects of these two social issues are such that the “Misery Index” is often calculated as the sum of inflation and unemployment rates. In this regard, the main objective of this paper is to analyze the effect of financial markets on the misery index in a group of selected countries with average income in the 2003-2014 period. Results from model estimation by the method of Generalized Method of Moments (GMM) show that: The trade volume to transaction volume ratio in a stock market (as an indicator of the capital market) has no effect on the misery index in the group of selected countries. Domestic credit to private sector by banks (as an indicator of the money market) has a negative and meaningful effect on misery index in the group of selected countries. Manuscript profile -

Th MoreAbstract In the last few years, the financial condition index has been an important indicator to determine the situation of each country. The Financial Conditions Index can be defined as the current state of the variables that affect the future state of the economy. The Financial Conditions Index is a summary index of financial variables that is effective in predicting the economic situation of a country. Financial conditions in any country are one of the most important issues in the economy. The purpose of this article is to determine and calculate the financial condition index for Iran using the basic component analysis method and time series data from 1990-2020. The results of calculating the financial condition index show that the credit channel has more weight than other channels and this shows the importance of the volume of credit in estimating the country's financial condition index during this period in the research. After that, the asset channel, ie the stock price index and the housing index, have the most weight. Among these, the exchange rate and interest rate channels have the lowest weight. Therefore, the central bank can adopt a forward-looking approach in monetary policy, so that by changing its retrospective approach in monetary policy decisions, it can show the most correct reaction.

In this paper, the effect of independent variables (liquidity risk, return on assets, capital adequacy ratio, etc.) on business cycles in selected countries through the output gap variable using the Hadrick Prescott filter is used to evaluate the results of the model. Liquidity risk, lending facility growth rates and financial crises have a negative impact on the output gap, while return on assets, capital adequacy ratio, crude oil prices, exchange rates and the development of financial markets have a negative impact on periods. Have left the trade of selected countries.The results of the study of the reactions of instantaneous reaction (IRF) and analysis of variance for developed countries show that a standard deviation in terms of oil price index and exchange rate on the output gap, these variables show a decrease of up to two periods. Increased development of financial markets and banking health has continued, after 2 periods of shock effect of oil prices and exchange rates over time on the output gap of developed countries will be minimized.Also for developing countries; a standard deviation from The area of oil price index and exchange rate on the output gap, these variables have increased up to two periods and after 4 periods, has decreased, in other words, the effect of oil prices on the production of developing countries shows that in periods Rising oil prices, investment and production have increased, and conversely, when oil revenues fall, we see a decline in production, in other words, rising oil revenues are largely unmanaged, in other words, long-term investments are spent on short-term expenditures. It has resulted in nothing but inflation and increased liquidity for these countries. Manuscript profile -
