Lending and financial institutions have looked for a variety of ways to expand their portfolios into agriculture, but because of the risks associated with lending to farmers who lack traditional forms of collateral, they face price and yield risks, causing these inroads to be limited. Market-based instruments are readily available for price risk. Organised exchanges offering the most basic of these instruments, futures and options, have operated for a long time, providing transparency to the market and low-cost risk transfer tools for those able to access them. While the use of price risk management instruments is an incomplete solution, it has sufficient merits on its own and will make the overall burden of risk more bearable. The use of these instruments... |

Some productivity measures area analyzed. The emphasis is on concepts, limitations and on some empirical results. Software is not discussed. The productivity measures are classified in optimized, whenever obtained by an optimization procedure, and not optimized, as yield, labor productivity and total factor productivity (ptf). The work shows when yields and total factor productivity say the same thing to conclude that this is possible only in a primitive agriculture where labor and land are the only factors of production used. This type of agriculture is present only in backward regions of Brazil. Hence yield, except in this situation, is a poor measure of profitability. Empirical works show that the development of Brazilian agriculture follows a path of... |

Megvizsgáljuk, hogy a borjak számviteli törvénynek megfelelő elszámolása hogyan hat az önköltségre, az eredményre és a vállalkozás vagyonára. Megállapítható, hogy az előhasi üszőktől született borjak növendékállományon belül történő elszámolásának hatása vagyont és eredményt csökkentő tételként jelentkezik. Azt, hogy az elszámolásban keletkező különbözet milyen arányban jelenik meg vagyont és eredményt csökkentő tételként, azt a korosbítás gyakorlata is jelentősen befolyásolja. Ha az állományt már az első korcsoport után szétválasztják, akkor nagyobb hányad kompenzálja a tejre jutó költségnövekedést és kisebb lesz a vagyoncsökkenés. ------------------------------------------------------ This study focuses on how recording of calves in accordance with the... |

Our study shows an analysis of a sheep farm. The present farm was chosen for analysis due to the fact that it is run under special natural conditions and as for the sheep farming, it has quite a few non-typical features. These raise some economic issues, which have to be analysed, questions have to be answered that may result in useful conclusions. Since sheep farming does not seem to be able to overcome its difficulties on its own, the EU support system could give the initial step necessary for the success and would also help to sustain sheep farms. The amount of grant that is usual in the EU could provide for the sustainability of this sector, the relative safety of sales, the equal chances of the farms operating under different capabilities and if... |

Multi-year nationwide survey data is used to estimate maize yield response functions and determine profitability of fertilizer use by small-scale farmers in Zambia. There has been a dearth of empirical studies on economics of fertilization in the context of Sub-Saharan Africa. In this paper we identify major methodological issues arising from using survey data and estimate maize yield response functions for small-scale rural households that have various management practices and soil conditions in two major agro-climatic zones. Profitability of fertilizer use is determined for each group of households. Our findings provide the following key messages. First, households that obtained fertilizer on time and used animal draught power or mechanical power for... |

Production functions to explain regional wheat yields have not been studied extensively in the Canadian prairies. The objective of this study is to employ a Just-Pope production function to examine the relationship between fertilizer inputs, soil quality, biodiversity indicators, cultivars qualifying for Plant Breeders’ Rights (PBR), and climatic conditions on the mean and variance of spring wheat yields. Using regional-level wheat data from Manitoba, Canada, model results show nitrogen fertilizer, temporal diversity, and PBR wheat cultivars are associated with increased yield variance. Mean wheat yield is reduced by the proportion of land in wheat, the interaction of growing temperature and precipitation, and spatial diversity. By contrast, higher soil... |

The feeding and the shelter are considered basic needs of the man and one of the options to satisfy them is through the lambs which contribute to cover them with their meat, wool and skin. For the analysis of the yield a flock took itself from twenty females and a stallion one of Pelibuey race and was developed in conditions of semiestabulado and artificial prairie with oats and rye grass in the north of the State of Sonora.Several indicators were taken to carry out the determination of the yield taking in first instance the capital of work, point of balance, sensitivity analysis as well as the relation benefit-cost. In the case of first the amount of 109.650,44 like so was determined whereas the balance point obtains as of the second period of 270 days... |

ABSTRACT: In banana cultivation, fertilization recommendations are almost exclusively based on soil chemical analysis, without considering leaf analysis and expected yield, which can help in the adjustment of fertilization programs. The aim of this study was to develop a method to recommend macronutrient fertilization rates which integrates data on leaf analysis, soil chemical analysis, and yield. Yield, soil chemical analysis, and leaf analysis data of fertigated plantations of ‘Prata’ banana were obtained for the first and second halves of the years from 2010 to 2015. Yield was correlated with soil organic matter (SOM) and soil contents of macronutrients (P, K, Ca, and Mg) to obtain the critical level (CLNui). Then, leaf nutrient contents were plotted on... |

Pig slurry (PS) represents an important nutrient source for plants and using it as fertilizer makes greater nutrient cycling in the environment possible. The aim of this study was to assess how PS application over a period of years can affect grain yield, dry matter production and nutrient accumulation in commercial grain and cover crops. The experiment was carried out in an experimental area of the Universidade Federal de Santa Maria, in Santa Maria, RS, Brazil, from May 2000 to January 2008. In this period, 19 grain and cover crops were grown with PS application before sowing, at rates of 0, 20, 40 and 80 m³ ha-1. The highest PS rate led to an increase in nutrient availability over the years, notably of P, but also of nutrients that are potentially toxic... |

ABSTRACT Brazilian soybean producers commonly apply maintenance potassium (K) fertilization during cultivation to restore the K taken up by plants; however, this measure can modify the morphophysiological plant characteristics, since the functions of K are closely related with plant growth and development. This study assessed the morphological changes in soybean plants in response to K rates, sowing fertilization, and the application periods of K fertilization in a Latossolo Vermelho eutroférrico (Oxisol) under a no-tillage system, located in the municipality of Floresta, Paraná. A randomized block design was used in the experiment with four replications in a fully crossed factorial design (5 × 2 × 2). The experiment was carried out in two growing seasons... |

ABSTRACT The objective of this study was to evaluate the agronomic variables due to the effects of different levels of defoliation in the phenological phases of two soybean cultivars. The experiment was conducted during the 2011/2012 season, in a randomized block design with three replicates, in a 2 x 4 x 5 factorial scheme. Two cultivars were exposed to defoliations of 0, 25, 50, 75 and 100% at the stages of V4, V9, R3 and R5. The cultivar 'NK 7059RR' showed less sensitivity to defoliation than the cultivar 'IN 4990RG'. 25% defoliation levels reduced the yield of the cultivar 'IN 4990RG', while levels of 75 and 100% reduce the number of grains per pod in both cultivars. The defoliation performed in the V4 stage lead to lower grain yield than defoliation... |
