    Resource Use Efficiency in Agriculture C. T. de Wit Department of Theoretical Production Ecology, Agricultural University, P.O. Box , AK Wageningen, The Netherlands ABSTRACT Trajectories over time of nitrogen use and yield show that the fertilizer is used as efficiently at the high end of the yield range, as at the low end. Supplement to reversing the spiral: the population, agriculture, and environment nexus in sub-Saharan Africa (English) Abstract. This document is a companion piece to "Reversing the spiral: the population, agriculture, and environment nexus in sub-Saharan Africa".

    The second part of the book (chapters 5 to 9) examines the implementation and impacts of the FISP from /6 to / Detailed information is provided on changing programme activities and costs, from national design and input procurement through voucher and input distribution to farmer access to and input use. Farmers in cooperatives have more bargaining power, lower transaction costs in getting loans, and better access to information. [12] Farmers have more individual power and control over production, including inputs and land use, than they do through contract farming, and therefore may be more food secure within a cooperative. [13] Since cooperatives are based on values .

      Global crop production tripled during the last 50 years, mainly by an increase in yield (production/area). We show that the energy embedded in the main oil-based inputs (machinery, fuel, and fertilizers) increased worldwide at a rate at first larger, but in the last decades slower, than crop production, resulting in a recent overall improved energy-use . Farmland Industries was the largest agricultural cooperative in North America when it eventually sold all of its assets in – During its year history, Farmland served its farmer membership as a diversified, integrated organization, playing a significant role in agricultural markets both domestically and worldwide.

[Olle Johansson; Lárus Jónsson; Organisation for Economic Co. Downloadable (with restrictions). In this study, energy use patterns and the relationship between energy inputs and yield for single crop (winter) greenhouse tomato production were examined in Antalya province, one of the most important greenhouse centres in Turkey.

Data were collected using face-to-face surveys from 85 farms producing winter greenhouse tomatoes. Agricultural input subsidies were a major feature of agricultural development policies in rural economies from the s to s. The theoretical case for agricultural subsidies is based on their promotion of agricultural productivity by making investment in new technologies more attractive to smallholder farmers.

If market failures mean that farmers’ private input costs are Author: Ephraim Chirwa. The importance of synthetic fertilizers as a nitrogen source (fertilizer-N) varies widely around the United States, depending on the crop and the region where that crop is grown.

Three of the four major commodity crops—corn, wheat, and cotton—use 61 percent of U.S. fertilizer-N. Corn, which covers about 21 percent of U.S. cropland. An Assessment of the Site-Specific Nutrient Management (SSNM) for Irrigated Rice in South East and South Asia.

Abstract: Site-specific nutrient management (SSNM) provides guidelines for effective nitrogen, phosphorus and potassium management to help farmers make better decisions on fertilizer input and output levels in rice study evaluates the assumptions.

The book focus on challenges, progress and prospects of crop production. It comprises of vast array of topics including latest agronomics practices for different crops to enhance productivity, mitigate the challenges imposed by climate change, improve water use efficiency, factors controlling dormancy, optimum use of fertilizers etc.

We used the food system framework including output and input markets. We explore three indicators of commercialization: Cash crop production share (CCPS), crop output market participation share (COMPS), and crop input market participation share (CIMPS) based on fertilizer use.

Nutrient use efficiency (NUE) is a critically important concept in the evaluation of crop production systems. It can be greatly impacted by fertilizer management as well as by.

The research design adopted for the study was a survey design. The data collected were tabulated and analyzed using the Ordinary Least Square (OLS).

The study revealed that a direct relationship exist between Production Characteristics (PC) and Value of Crop Output (VCO). Markets for major agricultural commodities are typically analyzed by looking at supply-and-use conditions and implications for prices.

From an economic perspective, these factors determine the market equilibrium. In the U.S. agricultural sector, many interactions and relationships exist between and among different commodities.

For example, corn production and prices affect. The book generates a comprehensive picture of the evolution and impact of farm co-operatives and fills a gap in the literature on the political economy of co-operative development in Ethiopia.

The data used in this study were based on cross-sectional data collected from growers by using a face to face survey.

The results revealed that diesel (%), fertilizer (%). Crop production is a branch of agriculture that deals with growing crops for use as food and fiber. Degree programs in crop production are available at undergraduate and graduate levels. credit has a positive effect on crop production, nonfarm employment.

Crop production to a great deal relies on the genetic diversity of crop plants. Since the very beginning of agriculture (more t years ago), during the process of domestication and cultivation of crop plants, a wealth of genetic diversity has been utilised.

distance from output markets also have significant and positive relationships to livestock net revenue, whereas distance from input (seeds and fertilizer) markets have a significant negative relationship. On the other hand, crop net revenue is dependent on soil types, access to irrigation, household size and distance from input markets.

In general, EI is primarily affected by fertilizer rate, especially that of N fertilizer, due to its high inherent energy intensity (Goglio et al., ; Rajaeifar et al., ; Wang et al., ).Therefore, even a moderate change in amount of fertilizer applied can strongly .Malawi, a small landlocked country, is highly dependent on the agricultural sector, particularly smallholder agriculture.

The structure of production and of the economy have not changed significantly since independence in smallholder agricultural productivity, which is dominated by maize, remains low while agriculture continues to contribute more than a third to GDP.
