state in the country with more than 1.5 million This study evaluates the economic suracres (USDA, Crop Production). vivability of rice farms in the Delta area of Since 1981, rice acreage in the Mississippi Mississippi. A general whole-farm simulation River Delta region, as in other rice-producing model, FLIPSIM V, is used to simulate the regions of the country, has generally declined. operations of representative rice farms over a Part of this acreage reduction was the result 10-year period. Although farm size did not of participation in federal farm programs. In change for any of the representative farms 1983, the PIK program was partly responsible considered, the financial structure of these for reducing harvested rice acreage in infarms changed considerably. Crop mix was dividual states to levels 40 to 50 percent of found to cause significant differences in the their 1981 acreage. However, other factors economic growth and financial viability of rice have also had an impact on rice-acreage levels farms in the region. in recent years. In the early 1980's, rising production costs reduced the profit margins asso

Comparing Geostatistical Seismic Inversion Based on Spectral Simulation with Deterministic Inversion: A Case Study
Seismic inversion is a method that extracts acoustic impedance data from the seismic traces. Source wavelets are band-limited, and thus seismic traces do not contain low and high frequency information. Therefore, there is a serious problem when the deterministic seismic inversion is applied to real data and the result of deterministic inversion is smooth. Low frequency component is obtained fro...

One of the reasons for the success of the agricultural sector in the developed countries is regulate the size of the farms, because it helps to scale economy of production. Considering that the size of agricultural production units should be specifically determined for each product and in each area, the aim of this study is to determine the optimum size of rice farms in the Fereydounkenar count...

Iran’s agricultural sector comparing with the other economic sector suffers from subsistence method. Small farm size, scatter distribution of holdings, lack of an appropriate irrigation and drainage systems, and non-existence of roads between farms have led to increase in production costs and reluctance regarding agriculture activities and relevant investment. This in turn demands the implement...

In Japan, greenhouse gas emissions from rice production, especially CH4 emissions in rice paddy fields, are the primary contributors to global warming from agriculture. When prolonged midseason drainage for mitigating CH4 emissions from rice paddy fields is practiced with environmentally friendly rice production based on reduced use of synthetic pesticides and chemical fertilizers, Japanese ric...

Using a deterministic model for dairy herd according to milk pricing system in Iran, the economic weights of milk production, fat percentage, protein percentage and herd life with minimized cost were identified, while restricted total input and total costs were variable in animal unit. By data simulation and the data obtained from 3 different dairy herds in Iran, the sensitivity of economic val...
