Agricultural Productivity in the United States AgEcon
Ahearn, Mary Clare; Yee, Jet; Ball, V. Eldon; Nehring, Richard F..
Increased productivity is a key to a healthy and thriving economy. Consequently, the trend in productivity, economywide, is one of the most closely watched of our common economic performance indicators. Agriculture, in particular, has been a very successful sector of the U.S. economy in terms of productivity growth. The U.S. farm sector has provided an abundance of output while using inputs efficiently. Agricultural productivity growth has been an important source of U.S. economic growth throughout the century, but the years since 1940 have seen an even faster growth in agricultural productivity. The annual average increase in productivity from 1948 to 1994 was 1.94 percent. This reflects an annual growth in output of 1.88 percent per year and an actual...

SANTOS, H. P. dos; IGNACZAK, J. C.; LHAMBY, J. C. B.; AMBROSI, I..
De 1980 a 1989, foi conduzido, no Centro Nacional de Pesquisa de Trigo, em Passo Fundo, RS, um experimento composto de quatro sistemas de rotacao de culturas para trigo: sistema I (trigo/soja); Sistema II (trigo/soja, colza/soja, cevada/soja e leguminosa/milho); sistema III(trigo/soja, leguminosa/leguminosa, leguminosa/milho, de 1980 a 1983; e trigo/soja, aveia branca/soja e leguminosa/milho, 1984 a 1989); e sistema IV (trigo/soja, colza/soja, linho/soja e leguminosa/milho). Utilizou-se o delineamento de blocos ao acaso, com quatro repeticoes e parcelas com area util de 120 m2. No presente trabalho, apresenta-se a analise economica relativa aquele periodo.

Assessment of the Farm Level Agronomic and Financial Benefits of the Magoye Ripper in Maize and Cotton Production in Southern and Eastern Provinces AgEcon
Kabwe, Stephen; Donovan, Cynthia; Samazaka, David.
This research focuses on the performance in the Magoye ripper in maize and cotton production in Eastern and Southern Provinces during the 2004/2005 productions year. Findings include the following: In maize production, the ripper enabled higher yields compared to traditional animal ploughing, by increasing the effectiveness of nitrogen fertilizer applications, resulting in net profits per hectare of ZK575,800 in Eastern Province and ZK93,800 in Southern Province; In cotton, the input applications and size of fields were the most important determinants of yield, and the ripper had no significant individual effect. Farmers using the ripper indicated that it helped conserve water, enabled early land preparation and early planting; and Farmers not using their...

Cost and Benefit Analysis of Tomato Spotted Wilt Virus (TSWV) Management Technology in Georgia. AgEcon
Fonsah, Esendugue Greg; Ferrer, Myra Clarisse R.; Riley, David G.; Sparks, Stormy; Langston, David.
Recent trend depicts that tomatoes and tomatoes products rank 2nd most important vegetable crop in the United States after potatoes and potatoes products contributing 20 percent of total vegetable production. More-so, tomato is equally ranked 2nd in the United States in terms of production value, generating $1.3 billion after head lettuce that contributed $1.4 billion in the same time period. In 2006, 422,000 acres of tomatoes were planted in the United States. Tomato is equally an important economic crop in the state of Georgia. In 2008, it ranked 14th in the Georgia vegetable acreage as 3,985 acres were planted. It also ranked 6th in terms of farm gate value in the same time period generating $51.2 million.

FORWARD CONTRACTING OF INPUTS: A FARM-LEVEL ANALYSIS AgEcon
Perry, Janet E.; Mishra, Ashok K..
Forward contracting of inputs in production agriculture is becoming increasingly important as more farmers attempt to manage risk. Using a logit model and farm-level data, this analysis estimates the effect of factors on the probability of a producer using forward input contracting. Results suggest that use of contracting in selling of crops and livestock, technology, farm size, geographic location, participation in government commodity programs, and use of extension services are important factors affecting the choice to forward contract inputs.

INPUT CHOICES IN AGRICULTURE: IS THERE A GENDER BIAS? AgEcon
Bhagowalia, Priya; Chen, Susan E.; Shively, Gerald E..
Most developing countries strive to improve agricultural productivity by relaxing credit constraints, supplying better inputs, and improving marketing and distribution. However the efficacy of these reforms needs to be examined in the context of the behavioral responses of farming households. This study examines gender biases within households that affect short-term decisions with immediate and long-term implications. This study utilizes data from ICRISAT's village level studies in India (1975-85) to highlight the effects of child gender on the use of agricultural inputs. The main finding is that households with boys tend to use purchased inputs such as fertilizers and insecticides more intensively compared with households with girls. In general, household...

Input Use and Conservation Investments among Farm Households in Rwanda: Patterns and Determinants AgEcon
Clay, Daniel C.; Kelly, Valerie A.; Mpyisi, Edson; Reardon, Thomas.
One of the Government of Rwanda’s key post-war policy objectives has been to increase agricultural productivity and ensure food security by promoting a transition from semi-subsistence production and marketing practices to intensive production and highly commercialized agricultural markets. The government wants farmers to increase land and labor productivity through the use of modern inputs, thereby generating substantial surpluses which can be sold to pay for inputs and generate increases in farm incomes.

Relações de troca com efeito tecnológico no mercado doméstico de arroz, milho, café e soja AgEcon
Ponciano, Niraldo Jose; Souza, Paulo Marcelo de; Mata, Henrique Tome Da Costa; Detmann, Edenio.
The objective of this work was to evaluate, by means of the exchange rate, the profitability of two products directed toward the domestic market and two export products. Other objective was to identify productivity growth compensated the decrease of prices. The geometric rates of the production, area and productivity growth were estimated. The exchange rate was estimated by the relation between the index of the inputs prices and the index of the product prices. The results show a great trend of deterioration of the exchange terms for all the analyzed products. Evidenced that these effects more was been accented for rice and maize. Such behavior associates it the fact of the rice cultures and of maize to be destined to the domestic market, its demands have...

Technology in the Differential Input Demand Model AgEcon
Brown, Mark G.; Lee, Jonq-Ying.
This study considers incorporating changes in technology in the differential input demand system through effects on output and input marginal products. The effects of technology on input demand are related to Slutsky coefficients and input shares of marginal cost. Technology effects on marginal-product changes are viewed as price changes, and restrictions on technology are considered.

Tecnologia cristalizada e produtividade total dos fatores AgEcon
Alves, Eliseu Roberto de Andrade.
Suppose that the production, y = f (x1, x2,..., xs ) , is known. It says that we are able to know for each value of the input vector, 1 2 , ,..., s x x x , the correspondent value of y. Or yet production growth occurs as consequence of movement along the production frontier, and it requires a different combination of inputs, and consequently, a higher or a smaller expenditure. Another representation of the production structure is, 1 2 ( , ,..., , ) s y = f x x x t , where t is non negative real number. Now each set of 1 2 , ,..., s x x x gives a different y as t varies. Or, it is possible to achieve a higher level of production with no additional cost. A question comes to mind: can the real world (or the data) say which one of the two representations has a...

What is the Difference in Profit per Acre between Organic and Conventional Coffee? AgEcon
Jensen, Jennifer; Dicks, Michael R..
The research addresses the economic problem of deforestation. A contributing factor to deforestation is coffee production. Coffee is an indigenous plant that is naturally occurring in the native tropical forests. However, conventional coffee is grown on cleared forest soil. In the native forest there is the potential for additional fruits (bananas, mangoes, avocados) and wood products while in the conventional coffee production system the only product is coffee. Conventional coffee production often causes deforestation and soil erosion while the organic coffee production system does not. In addition, the price risk associated with the coffee monoculture is high and has proven disastrous to the sustainability of coffee production in past years. Thus,...
