ABSTRACT Excessive tillage operations under inadequate conditions can raise the cost of agricultural production and lead to soil degradation without adequate crop response. The objective of this study was to evaluate the onion crop response to soil water contents and tillage systems. Three tillage systems were evaluated: P1 (plowing + two harrowings + two seedbed raising operations), P2 (two harrowings + one seedbed raising operation), P3 (one harrowing + one seedbed raising operation); and four soil water contents: 12, 15, 23 and 26%. The experiment was conducted in the irrigated perimeter of Tourão, Juazeiro, BA, Brazil (9° 24’ 7.3” S; 40° 26’ 8.7” W and altitude of 368 m), in 2017, and was installed in split plots, in a randomized block design, with... |

The Barakat Fruit Farm desires to increase their share of the exportable grape market in Egypt. Unfortunately, the grape cultivars currently cultivated by the farm bear fruit after the early market window to the European Union when prices are high. An analysis of the company, competition, consumer, market channel, and conditions, provides insight into possible solutions to the challenges faced by the farm management. Designed for undergraduate classroom use, this case encourages students to think outside of traditional production techniques to arrive at solutions that are viable from both crop culture and financial standpoints. |

Gulupa, Passiflora edulis Sims (Passifloraceae), is an important fruit due to its organoleptic and nutritional characteristics and its demand in the international market; however, very few studies have been conducted for studying its Ecophysiology. Until now, this crop has spread throughout the country through empirical knowledge without data that indicate the zones that are more suitable for its cultivation. For this reason, gas exchange, chlorophyll fluorescence (photosystem II operating efficiency and maximum quantum efficiency of photosystem II photochemistry) and leaf water potential were measured in three different locations of Cundinamarca department (Chia [2610 m a.s.l., 14 °C], Granada [2230 m a.s.l., 15 °C] and Tena [2090 m a.s.l., 17 °C]), whose... |

The potential for improving irrigation scheduling decisions and adoption of more efficient irrigation systems is explored using a bioeconomic simulation model of lettuce production on the Gnangara Mound near Perth, Western Australia. Sandy soils with poor water and nutrient holding capacity are associated with declining marginal productivity of water at high water use, which would create an incentive to reduce water use and to adopt closer sprinkler spacing if farmers had correct information about the declining marginal productivity of water. Incorrect perceptions regarding water–yield relationships lead to over use of water by up to 50 per cent and reduce profits by $475 per crop hectare (12 per cent) in the short run, and remove the incentive to adopt... |

The AgroFood Company, which currently exports fresh chili peppers to European clients, desires to expand the product mix offered. The company, as it expands its production of fresh peppers for export, has an increasing supply of grade 2 peppers that are unmarketable in Egypt. However, an attractive market for processed frozen chili peppers exists in Europe. To expand their client base, capitalize on a value added product, and minimize product waste, the AgroFood Company desires to develop processing practices for chili peppers produced in Egypt. The AgroFood Company would like to identify its options in the processed pepper market. An analysis of the company, competition, consumer, market channel, and conditions, provides insight into possible solutions to... |

The supermarket revolution has arrived in China and is spreading as fast as or faster than anywhere in the world. As the demand for vegetables, fruit, nuts and other high valued products have risen, urban retailers are finding new venues seized on niche and today have over $55 billion in sales, more than a third of the urban food market. However, the experience of many developing countries suggests that there could be serious distributional impacts of the rising of supermarkets. There is concern among policy makers and academics that poor, small farmers might be excluded from market. The main goal of our paper is to understand what types of farmers have been able to participate in the horticultural revolution, how they interact with markets and how... |

The development of consumer-driven, efficient, responsive and innovative supply chains is crucial for the growth of fruit consumption in Europe and for a competitive, sustainable fruit sector. Currently, fruit supply chains are characterized by a relatively low level of consumer orientation and consumer-driven innovations. The awareness of the functioning of supply chains in the European fruit sector should be increased to be able to increase the level of consumer-drivenness, efficiency, and responsiveness of fruit supply chains. This paper presents the results of review of fruit supply chains’ from the fruit industry in Poland. The analysis of supply chains is preceded by a review of fruit consumption, fruit production, trade characteristic and trends.... |

ABSTRACT The use of brackish water in hydroponic crops represents an alternative for vegetable production. In this context, two experiments were conducted to evaluate the effect of using brackish water to prepare the nutrient solution and replace the evapotranspired depth, applied at different flow rates, on cauliflower biometrics in NFT (nutrient film technique) hydroponic system. In both experiments, the experimental design was completely randomized with four repetitions, in a 6 x 2 factorial scheme: six levels of water electrical conductivity (ECw) in interaction with two flow rates of nutrient solution application in the hydroponic channels (1.5 and 2.5 L min-1). In Experiment I, brackish waters with different EC (1.5, 2.5, 3.5, 4.5 and 5.5 dS m-1),... |

Abstract The type of environment and substrates quality in seedlings production are essential for the production of productive plants under field conditions. In order to determine the best environment and substrate for seedlings production of two tomato cultivars (IPA 06 and Santamélia), two experiments, completely randomized and arranged in subdivided plots with five replicates, were conducted under the environmental conditions of Boa Vista, Roraima, Brazil. Treatments consisted of the association among five environments (A1 - greenhouse, A2 - Chromatinet ® 35% red, A3 - Chromatinet ® 50% red, A4 - Chromatinet ® 35% Silver and A5 - Chromatinet ® 50% Silver) and four substrates S1 - OrganoAmazon®; S2 -OrganoAmazon® + PuroHumus®; S3 - OrganoAmazon® +... |

This paper applies a semi-parametric approach to estimating a generalised model of investments in energy installations. The model accounts for irreversibility and lumpiness of investments by linking a parametric specification of the unobservable dynamic shadow price to observed investment behaviour using a non-parametric specification of the adjustment cost function. The results suggest that marginal costs of investments in energy installations increase quickly at small investment levels, whereas the increase slows down at higher investment levels. Therefore, standard parametric adjustment cost models are likely biased such that they over-estimate small investments and under-estimate large investments. |

In the last few years, precision agriculture has become commonly used with many crops, particularly cereals, and there is also interest in precision horticulture. Pear is a seasonal fruit and well appreciated by Brazilian people, although it is mostly imported. Brazilian farmers are nowadays trying to increase pear production. Thus, this research aimed at mapping the yield of pear trees in order to study the spatial variability of yield as well as its comparison with spatial variability of soil and plant attributes. The experimental field had 146 pear trees, variety 'Pêra d'água', distributed on a 1.24 ha. Four harvests were performed according to the fruit ripening and from each tree; only the ripe fruits were harvested. In each harvest, all the fruits... |

This paper examined the relationships between growers choice of market channel (emphasizing the supermarket market-channel versus others), technology use, and grower characteristics such as human capital and farm size. Three key findings emerged. First, both tomato and lettuce growers selling to the supermarket market-channel had more human capital than those not participating. Second, while farm size was important in whether lettuce growers sell to supermarkets, it was not important for tomato growers. Third, technology use was significantly more capital-intensive among lettuce growers selling to the supermarket channels, however, that was generally not the case for tomato growers. These results are important to agribusiness researchers and policymakers... |
