    Field experiment was conducted, during two successive seasons of 2014- 2015 and 2015- 2016, at Dokki protected agricultural site, Giza Governorate, Egypt, to study the profitability of different applied irrigation levels and polyethylene (PE) mulch on plant growth and yield of sweet pepper, (Capsicum annum L.) cv. Godion F1, under plastic house condition. Three irrigation levels (0.50, 0.75 and 1.00) of crop evapotranspiration (ETc), using drip irrigation system and three PE mulch treatments (transparent, black and control) were applied. Data revealed that black PE recorded the highest values of early and total fruit yield per plant during the two seasons. Increasing water level up to 1.00 (ETc) enhanced yield with different PE mulch treatments, while water use efficiency (WUE) decreased with increasing water level. However, Using 0.50 (ETc), with different PE mulches increased WUE compared to using 0.75 (ETc) or 1.00 (ETc). The economic assessment of costs and returns from different treatments were calculated. It was found that the average yield was higher in 1.00 ETc with black mulch. Gross margin per 540 m2 were analysed using yield data, price structures and production costs. The 1.00 (ETc) with black mulch had the highest gross margin which is USD 416.8 and USD 533 (1 USD= 9 Egyptian pound) for the first and second seasons, respectively. The benefit cost ratios (BCRs) per 540 m2 were analysed, and 1.00 (ETc) with black mulch had the highest BCR with 1.36 in the first season and 1.45 in the second season.

  • Economic, practical impacts of precision farming – with especial regard to harvesting
    141-146

    Today agricultural practice is faced with a paradigm shift. In terms of natural resources, the World’s growing population calls for rational management and environment-conscious behaviour. Precision farming may provide a solution for the above mentioned criteria and problems. It has an array of technological equipment, elements and complete systems which are in themselves suitable to create conditions for efficient farming, to reduce environmental load and to provide farmers with optimal return on their investment. Agricultural production has started to focus mainly on efficient crop production and machine operation. Due to this trend, machinery exploitation emerges as a secondary priority for agricultural enterprises. The underlying reason behind this shift is primarily the rise of machinery operation costs. Efficient machinery operation can provide farmers with a solution to reduce their expenditure and through better logistical organization they can obtain extra returns. On the leading edge of my research is to introduce, quantitatively underpin and to justify the application of precision technologies. Our fundamental research methods rely on scenarios and economic calculations.

    The living standard of smallholder cocoa farmers in Tanzania was still low despite the recent transformation in marketing structure which led to the sharp rise in price. This study aimed at examining the drivers for smallholder cocoa farmers in Kilombero, Tanzania to engage in multiple crops farming as the means of poverty alleviation. Based on the cross-sectional survey design, primary data were collected from 501 cocoa farmers obtained through a random selection process that was conducted in their respective 162 agricultural marketing and cooperative societies (AMCOS) found in Kilombero. Results from covariance-based structural equation modeling (SEM) revealed that, cocoa market price, payment waiting time, farm size and cocoa farm income played significant roles in cocoa farmers’ decisions to invest while taking into account their perceptions of success. It was only the off-farm income factor that was found to have no statistical significance on farmers’ decision to invest while considering the mediation effect of perception. The study just assessed the investment decisions by smallholder cocoa farmers in Tanzania. Policy makers need to enhance the marketing factors such as cocoa price and payment time to boost farmers’ financial muscles. Meanwhile, farmers themselves are advised to take measures to boost production by increasing farm sizes while adopting better agronomic as per extension officers’ training.This study contributed to knowledge gap by exploring the cocoa-related factors that affect the stallholders’ decision to invest in crop diversification other than the non-cocoa factors that were investigated in previous studies.

    By applying precision nutrition the yield heterogeneity owing to the different features of soil spots can be taken into consideration. The planned and sprayed fertilizer adjusted to the expected yield rendered to soil spots can reduce the negative effects of artificial chemicals on soil and environment. The aim of this paper is to examine how the quantity and the cost of fertilizer (material and operational) will change on spot level on a certain plot during a five-year period, considering crop rotation, too. The following crops are in the rotation: winter wheat, corn and sunflower. Precision nutrition can be used in all the cultures mentioned above. Our earlier (static) model calculations have revealed that the threshold price of precision production was lower by 31% than in conventional technology. So it is necessary to explore for a longer period how the profitability of precision nutrition reacts to the changes in input and yield prices in different crops. The risk receptivity of precision nutrition can be characterized with the help of price sensitive analyses. Effects on profitability of other technological elements are not analysed in this paper.

  • Effect of uncertainty on farmers decision making: Case of animal manure use

    Due to the high levels of manure application and the poor use efficiency of manure, the European agriculture is held responsible for a considerable negative impact on surface water quality (Langeveld et al., 2007). This problem has emerged particularly in Western-European countries such as the UK, Belgium, The Netherlands and Denmark, facing a large expansion and intensification process in the livestock production since the 1960s (Van der Straeten et al., 2008). Policy measures related to the application of manure on the land encompass two major measures: emission rights, understood as the amount of nutrients which can be applied on the land, differentiated by crop and the N spreading calendars, whereby the manure can only be applied when the crop needs nutrients. The fundamental aim of this pillar is to maximising application rate while avoiding overfertilisation. Maximizing the application rate is related to the economic sustainability of the agricultural sector, by altering the manure surplus, while avoiding overfertilisation is imperative in enhancing ecological sustainability, by preventing nitrate leaching to surface and soil waters. For nitrate policy to meet its target, the farmers should not exceed their emission rights, however make optimal use of their emission right for manure. Consequently, the successful implementation of sink-related measures will strongly depend of the absorptive capacity of farmers towards new ways of nutrient management in general and of animal manures in particular.

  • Water footprint in Hungary

    More and more news report on water-related extreme environmental phenomena. Some of these are natural, which are often beyond the human race. But others are definitely due to anthropogenic effects. I think the water footprint index is able to highlight national and international water-use processes and gives us the opportunity of organizing a sustainable, consumer-, environmental- and governancefriendly management. 81% of the fresh water withdrawal is from surface water bodies in the EU. In Europe as a whole, 44% of abstraction is used for energy production, 24% for agriculture, 21% for public water supply and 11% for industry. Public water supply is confined to ground waters. To the water resources related human activity caused qualitative and quantitative amortisation will grow worse in the foreseeable future due to the climate change. Beside seasonal differences the sectoral differences are increasingly becoming critical between different areas, such as Southern and Western Europe. The former, wrong agricultural support system has worsened the situation since it gave financial aid for the used improper techniques of water-intensive crop cultivation. By today, this seems to be solved. Public water abstraction is affected by many factors, of which mostly are based on social situation and habits, but technological leakage receives a big role as well. Interesting, that for example the residents’water consumption in Eastern Europe decreased because price were raised and regular measurements were introduced. But in Southern Europe it increased due to tourism in the past period. Industrial water withdrawal decreased across Europe because of the decline of industry and the development of technologies. According to the European Environment Agency (EEA), the Union needs a sustainable, demand-driven leadership which focuses on the preservation and use efficiency. This have already appeared in politics and legal administration as well. Current research calls the attention to the significance and difficulties of this kind of domestic estimation presented trough the water footprint calculation of bread and pork in Hungary. The received data indicate the domestic water consumption trends in a modern approach. There is no doubt for me about the urgent necessity of water footprint calculation because as a result innovative, sustainability supported environmental, social, economical, and political relationships can be created – not just on local, regional or national level, but on interregional, European and even global stage.

    This study provides a disaggregated analysis of the effects of monetary policy shocks on the agricultural sector in Nigeria from 1981Q1 to 2016Q4. The study utilized the generalized impulse responses and the normalized generalized forecast error variance decompositions from an underlying VAR model, which are order-invariant. The four monetary policy variables used in the study are interbank call rate, monetary policy rate, broad money supply and exchange rate; while the four agricultural sub-sectors investigated are crop production, forestry, fishing and livestock. The study also controlled for the general price level and other economic activities in the overall economy. The findings indicate that the aggregate agricultural sector and its various sub-sectors consistently responded negatively to unanticipated monetary tightening in most of the forecast horizon; while the immediate impact of monetary policy shocks is transmitted to the agricultural sector through the interest rate and money demand (credit) channels. The findings further indicate that apart from these two channels, the roles of monetary policy rate and exchange rate are non-negligible in the long-run. The role of money supply channel in spreading monetary policy shocks to the agricultural sector remained muted all through. The study concludes that the monetary authority should evolve interest rate, credit, and exchange rate policies that will promote the development of the agricultural sector in Nigeria.

    Pressure on natural resources and the global environment have been identified as the most important challenges to maintain prosperity and improve environmental care. Agriculture is responsible for only a small proportion of carbon dioxide (CO2) emissions, but the sector is more closely associated with emissions of other greenhouse gases such as methane (CH4) and nitrous oxide (N2O). The global warming potential of agricultural activities defined as greenhouse gas (GHG) emissions in CO2 equivalents is relatively low in Hungary, when calculated per land area. However this difference decline, when a GHG emission is calculated per product unit, as yields are lower then in West European countries. Environmental load caused by agriculture is also low in Hungary, where increasing part of EU resources are used for the long-term preservation of natural resources and for the raising of awareness of sustainable farming. The strength of the environmental situation of Hungary, consist of several elements, such as the rich bio-diversity, the significant size of territories falling under natural protection, the extent and importance of forests and the low environmental load from crop production. Among the weaknesses the nitrate load of the animal husbandry farms, the increasing water and wind erosion, the soil compaction and degradation have to be taken into consideration. Climate change has high risk potential and the mitigation activities of the New Hungary Rural Development Programme (HRDP) are investigated in this paper with the aim to increase mitigation activities in rural area and reduce the causes of climate change.

    Agriculture is one of the most important sectors for the Mongolian economy. Also, self-sufficient food is a significant target that has a vital role in the food safety of people in Mongolia. But due to climate change, not proper management, and lack of technology, the Mongolian agricultural sector is facing several issues. So this article aims to find some potential solutions to improve this situation, especially for the crop production sector in Mongolia. To define the current situation of Mongolian agriculture, we used statistical data and reports and recent scientific articles as well as online sources. The current situation of Mongolian agriculture is defined using SWOT analysis reported by the Ministry of Food, Agriculture, and Light Industry of Mongolia. Based on this research, we discuss the possibility of using a drone to improve the performance of agriculture in Mongolia. As a result, a drone is effective in enhancing the performance of agriculture performed by householders. Also, two effective models that are based on ICTs to address soil erosion and harvest losses issues in Mongolia are defined in this article.
