“…The NGMC, calculated by applying Equations [3] to [5] and RGMC, applying the CF to bean and sugar beet (Figure 1), which generated the highest average real net benefit (US$5169 and US$4775 ha -1 , respectively). Tzilivakis et al (2005) reported yields between 50 and 55 Mg ha -1 for sugar beets in a production system under irrigation in the UK, resulting in net incomes of up to US$994, which is lower than the values obtained in this study, taking into account that results were evaluated in volcanic soils under irrigation with contract farming. Wheat generated a RGMC of US$1051 ha -1 , barley US$711 ha -1 , and grain corn US$1691 ha -1 , which are economically attractive results, although lower than bean and sugar beet.…”

The sustainable use of productive resources by agricultural producers in the central valley of Chile should be compatible with economic results so that producers can select an appropriate rotation or succession of annual crops and pasture. The objective of this work was to evaluate the economic behavior of four food crop and supplementary forage rotations using indicators of profitability and profit variability. Productive data were used from a long-term experiment (16 yr) in the central valley of Chile under conditions of irrigation. With productive data and information on historic input/output prices, the real net margin per rotation (RNMR) and its coefficient of variation (CV) were determined. The results indicated that the highest economic benefits and greatest economic stability were obtained with rotations that only included crops, namely sugar beet (Beta vulgaris L. subsp. vulgaris)-wheat (Triticum aestivum L.)-bean (Phaseolus vulgaris L.)-barley (Hordeum vulgare L.) (CR2) and corn (Zea mays L.)-wheat-bean-barley (CR4). These rotations included crops with low CV of the net margin, such as wheat, barley and beans, with values between 0.31 and 0.34. The rotations with crops and pasture, sugar beet-wheat-red clover (Trifolium pratense L.) (2) (CR1) and corn-wheat-red clover (2) (CR3) had lower net margins and more variability of this indicator. Red clover had the highest CV value (1.00). The selection of crops for rotations and their sequence were determining factors in the economic behavior of rotations, affecting the level of RNMR and the degree of inter-annual variability of this indicator. Thus, differences among rotations of 47% in net margin were determined (CR2 vs. CR1), which only differed in the replacement of pasture with red clover (2) by bean-barley. The economic analysis based on the net margin and its variability allow for discriminating among rotations, providing valuable information for producers in deciding which crops to use in rotations.

“…In the case of labour costs, organic farmers invest more time in manual weeding out. Other authors, such as Tzilivakis et al (2005), pointed out that the profitability of organic crops depends heavily on the weed control costs.…”

“…But, as Norris (2001) already stated, the separation of environmental assessment from economic analysis limits the influence and relevance of LCA for decision-making, and does not characterize the important relationships and trade-offs between the economic and life cycle environmental performance of alternative product design decision scenarios. Since then, several studies have examined the relationship between environmental efficiency and profits in agricultural production (Tzilivakis et al, 2005;Thomassen et al, 2009;Jan et al, 2012).…”

Influence of management practices on economic and environmental performance of crops.A case study in Spanish horticulture. AbstractThis paper assesses the effect of management practices on the environmental and economic performance of tigernut production in Spain. Tigernut is a horticultural crop grown in a very limited area with homogenous climate and soil; thus the influence of these surrounding factors on the agricultural practices and their subsequent impact can be overlooked. From an environmental perspective, the variability among farms was much greater than the one of the costs. A principal component analysis showed that keeping some impacts low would also decrease the costs. Results highlight how proper management leads to both relatively low environmental impacts and costs.

“…Taheri-Rad et al (2014) reported that GHG emissions from diesel fuel was 646.23 kg of CO 2 per ha that had 45% of GHG emissions of cotton production in Golestan province, followed by manure with 23% of GHG emissions. In this regard, Tzilivakis et al (2005a) estimated the total GWP values per area for potato products, wheat, oilseed rape, barley, and chickpea as 3, 1.7, 1.2, 0.7, and 0.7 tons equivalent to CO 2 per ha. The results of the present research showed that manure was not used in 60% of farms; hence, GHG emissions in these fields was zero (Fig.…”

“…Agriculture has led to the production of greenhouse harmful gases (Johnson et al, 2007). Greenhouse gas (GHG) emission reduction is possible by minimizing fossil fuels burning and applying effective strategies to reduce global warming (Tzilivakis et al, 2005a). The reduction in fuel consumption is also important for the production of sustainable agricultural products, in order to return economic optimization and the preservation of fossil fuel reserves (Pervanchon et al, 2002;Rathke and Diepenbrock, 2006).…”

Abstract. Careful choosing of appropriate methods in farming operations reduces fuel consumption, energy, and Greenhouse Gas (GHG) emissions in agricultural production. The present study was conducted to investigate the input and output energies and GHG emissions in cotton production in Golestan Province of Iran and the cities of Ali Abad Katool and Aqqala. For this purpose, agricultural operations were randomly selected from 100 farms for the years 2014 and 2015 and the related data on all farms were recorded. Various inputs and comprehensive information at every phase from planting to harvesting were collected, recorded, and processed and then extracted from multiple sources for each equivalence operation during different crop operations for cotton production using a conversion ratio of energy and GHG emissions. Afterward, the energy and GHG emissions for each input and operation were calculated. According to the obtained results, the mean power output was 154 GJ per ha, which is approximately six times of the average input energy (26 GJ/ha). The output and input energies for cotton production were 49 to 243 and 15 to 43 GJ/ha, respectively. Moreover, Global Warming Potential (GWP) of various activities in the cotton fields varied between 741 up to 7790 kg CO 2 equivalent per ha. The maximum GHG emissions were related to fertilizers with manure and fuel ranked in the next orders. The comparison between input energy and GWP revealed their direct relation in cotton production farms. Irrigation, feeding, and preparation operations had the highest fuel consumption and led to an increase in GHG release. Based on these results, it can be concluded that energy consumption and GHG emissions can be reduced by lowering fuel consumption and using chemical fertilizers.
