Abstract:

In this 2-year study, ‘Brown Snout’ specialty cider apples (Malus ×domestica) that had been hand harvested or machine harvested with an over-the-row shake-and-catch small fruit harvester were ambient stored (56 °F mean temperature) for 0, 2, and 4 weeks to evaluate yield, fruit damage, yield loss, and juice quality characteristics. The average yield (pounds per acre) of fruit picked and retained by the mechanical harvester was 74% that of the hand-harvest yield and 81% that of the hand-harvest yield when fruit that fell out of the harvester was included in the machine-harvest yield. Percent fruit bruised and cut were greater for machine harvest (97.5% and 25.5%, respectively) than for hand harvest (47% and 0.5%, respectively), on average for 2014 and 2015. Yield loss to rot was greater for machine harvest than for hand harvest, and increased for both methods over time; percent rot doubled from 2 to 4 weeks storage for machine harvest (22% to 41%), and while negligible, tripled from 2 to 4 weeks storage for hand harvest (0.7% to 2.1%). Juice quality characteristics did not differ due to harvest method, but did differ due to year and storage time. Soluble solids concentration [SSC (%)] and specific gravity (SG) did not change due to storage in 2014, but in 2015, SSC and SG were greater on average for 2 and 4 weeks storage duration (15% and 1.062, respectively) than at harvest (13.31% and 1.056, respectively). Titratable acidity (grams per liter malic acid) decreased in 2014 from 2.98 g·L−1 at harvest to 2.70 g·L−1 on average for 2 and 4 weeks storage duration, but did not differ due to storage in 2015. Tannin [tannic acid equivalent (%)] was unchanged in 2014 from harvest to 4 weeks storage, but increased in 2015 from 0.16% at harvest to 0.19% by 4 weeks storage. These results indicate that harvest efficiency could be improved with some engineering modifications of the over-the-row mechanical harvester and training modifications for the trees. A comparison of the aromatic and phenolic contents of mechanically harvested and hand-harvested ‘Brown Snout’ would be a valuable next step in evaluating shake-and-catch mechanical harvest technology for cider apple production.

Abstract:

Subterranean clover (Trifolium subterraneum L.) is Australia’s most widely sown annual pasture legume. Its widespread use as a pasture plant requires a well-functioning seed production industry, and Australia is the only significant producer of subterranean clover seed globally. However, the sustainability of this industry is under threat due to its reliance on ageing harvest equipment and the resultant environmental impacts. In order to evaluate seed harvesting practices, technology, and issues, we report on case studies, workshops, and a survey of seed producers across southern Australia. The Horwood Bagshaw Clover Harvester, designed in the 1950s, remains the most popular subterranean clover seed harvester. We discuss its use and modifications, and document several contemporary issues facing the seed production industry. Issues are primarily soil erosion and degradation; the expensive, slow and labour-intensive harvest process; and poor reliability and maintainability of harvesters that are now at least 30 years old. We conclude the root cause of these issues is the suction harvest technology utilised by the Horwood Bagshaw Clover Harvester. Analysis of the current harvest system is provided to support the development of new approaches to harvest subterranean clover seeds.

Abstract:

<p>Aquaponics is an integrated food production technology of aquaculture and hydroponics. Lettuce (<em>Lactuca sativa </em>L.) is an economically important vegetable crop that can be grown aquaponically. In addition to selecting the right choice of lettuce cultivars, developing an optimal harvest strategy could increase lettuce production. Lettuce production using two harvest methods, Cut-and-Come-Again (CC) and Once-and-Done (OD), was evaluated using ‘Red Sails’ lettuce in a flow-through aquaponic system rearing trout. With the CC method continual harvesting was possible on a weekly basis after the initial harvest, while it took five weeks for each harvest using the OD method. The total yield of lettuce by the CC method was 6.7 kg from 9 trays, while 22.6 kg of lettuce was harvested by the OD method using 54 trays. In harvests by the OD method, 6 times as many seeds were sown compared to the CC method. The average yield per tray harvested by the CC method (744.4 g/tray) was 78% higher than that by the OD method (418.5 g/tray) because the CC method used 6 times less trays. Productivity, calculated by the average yield per growing week, of the two harvest methods at the first harvest was similar, but 4.8 times higher in the CC method than in the OD method at the second harvest due to the shorter harvest time. However, visual and decay ratings of lettuce harvested by the CC method began to decline afterwards. Together, the OD method after two consecutive harvests by the CC method would help growers to obtain increased yield of quality lettuce.</p>

Abstract:

Harvest of fresh market, southern highbush blueberries (SHB) is labor intensive and costly, leading to a demand for alternative harvest methods. Recent research has shown potential for mechanically harvesting blueberries with minimal bruising by using a modified over-the-row (OTR) harvester. For two harvests, SHB cultivars Optimus and Vireo were either hand-harvested (HH) or mechanically harvested (MH) by two commercial harvesters, one unmodified with standard hard-catch surfaces (HCS) or by the other modified with soft-catch surfaces (SCS). For Harvest 1, fruit from all harvest methods were hand-sorted into the following categories: blue fruit (marketable), red fruit, green fruit and culls. Samples from each cultivar and treatment were then held at 24 °C overnight, and the following day firmness and impact bruise severity were determined. Harvest 2 had identical harvest treatments; however, the fruit were sorted on a commercial packing line prior to packing in clamshells (n = 16). A subsample was held overnight as in Harvest 1 for bruise severity rating, while the remaining fruit were stored at 1 °C for 14 days (d). Although percent marketable fruit was more affected by cultivar than harvest method, determination of bruise severity revealed the benefit of harvest with SCS over HCS for both cultivars. The former had 16–26% severe bruising, compared to 27–40% for the latter; HH had 1–4%. During storage, HH fruit remained firmer than HCS and SCS, which were similar. After 14 d, firmness for “Optimus” was 239 N (HH), 157 N (HCS and SCS) and for “Vireo” it was 189 (HH), 155 N (HCS and SCS). Fruit weight loss increased during storage (1.1–4.4%), but there was no difference due to catch plate surface. SSC, TTA and Ratio were not affected by catch surface type or storage period within cultivar. Using modifications such as “soft” catch surfaces on currently available OTR harvesters reduces impact bruise damage; however, impacts incurred during commercial packing operations can negate this effect. MH for fresh market blueberries may provide an economical alternative for blueberry growers; however, with current technology, the fruit should be utilized within a week of harvest.

Abstract:

Australia's outstanding economic success in recent years has been aided by significant developments in science and technology research and by the ways in which research has been exploited for commercial development. Australia's success in this respect, and its rapid and sometimes innovative development of such vehicles for R&D exploitation as science and technology parks, makes it a suitable case for study. This paper arises from the findings of a study mission from the UK, which set out to identify and analyse the various ways in which Australia is addressing the challenge of science and technology exploitation. The authors focus on current science, technology and innovation policies at state and national levels, and assess the various ways in which science and technology parks have been used as vehicles for innovation, business development and economic regeneration. The paper is divided into three main parts: Part 1 discusses policy issues at state and Commonwealth levels; Part 2 is concerned with technology, innovation and economic regeneration and describes various science and technology park developments; and Part 3 assesses the ways in which university-industry links are manifested in science and technology parks. A concluding section summarizes the key aspects of Australia's strategy for economic development through science and technology, in terms of both policy and implementation.

Abstract:

Limited facilities and infrastructure in rice farming activities, especially in post-harvest processing has resulted in a farming communities become unproductive to processing their harvested products. Despite these problems has been tried to be overcome by the farming communities by making some tools for agricultural needs with tools and improvised materials, like a self-made rice thresher tools that made from used wood waste, of course the ability of productivity is very much different when using factory-made rice thresher. This PKM activity aims to introduce and train the farming communities to be able to process their rice crop yields using appropriate technology, like with a rice thresher machine and a rice husk machine. The main target in this PKM activity is a community of Tani Jaya Mandiri Group which in Kelurahan Batu Layang RT05/RW13 Kecamatan Pontianak Utara, which still has limited facilities for their agricultural activities. The method applied in this PKM activity is the diffusion of science and technology, socialization and active participation from the community. So with the existence of this PKM activity, the farming community get knowledge and skills in processing their post-harvest rice products, and is expected to be able to help overcome their productiviy problems due to the limited agricultural facilities they have

Abstract:

Improvements in the Bragg harvester and the introduction of a new Nimco harvester warranted a reevaluation of new technologies. Four technologies: the Bragg harvester, a modified Bragg harvester, the Nimco prototype, and hand-harvesting were evaluated at two locations: a land-leveled field (T-19) and a field without land leveling (Deblois). The experimental design was a randomized complete block with eight replications. A 150-ft strip was harvested with each technology, with strips directly adjacent to each other to minimize field variability. Time to harvest and berry weights were measured. Poor maintenance, adjustment and skill of the operator contributed to a 69% recovery relative to hand-harvest by both the Bragg and modified Bragg harvesters. The Nimco harvester has great potential, but only if it is properly mounted to allow it to cover the fields at a speed similar to the Bragg harvesters. The land-leveled field allowed for greater recovery for the Bragg and Nimco harvester, indicating that smoother fields are more efficient for machine-harvesting.

Abstract:

Smartphone centric ubiquitous sensing applications use a smartphone with external sensors. The 3.5mm audio interface provide a common data interface for communication in different smartphones. The 3.5mm audio interface cannot provide DC power to external sensors. Thus, power needs to be harvested from an earphone channel. The existing technology uses one earphone channel to harvest power. Consequently, for many smartphones the technology cannot harvest enough power to support external sensors. In this paper, based on frequency shift keying (FSK) modulation scheme, the authors have proposed a joint power harvesting and communication technology that can simultaneously harvest power and transfer data with the same earphone channels. Circuit measurements show that, the proposed technology can extract more than two times of power as from one earphone channel. Meanwhile, demodulation tests show that our newly-developed timer-based FSK demodulator can reliably recover the data transferred from a smartphone to external sensors without any error.

Abstract:

Vegetable soybean (Glycine max L.) represents a potential high-value specialty crop for small farmers in the southern Piedmont region of the United States; practical and affordable mechanical harvest technology will facilitate production. A trial planting of vegetable soybean was used to test the ability of a commercial one-row harvester used currently for snap bean and lima bean production systems to harvest soybean. The upright growth habit and excessive herbage of vegetable soybean necessitated harvest in two passes over the row, which produced in-pod yield of 7050 lb/acre (7900 kg ha-1). Adaptation of this technology has the potential to facilitate development of a vegetable soybean production industry.

Abstract:

Deere & Co., the Moline, IL, agricultural equipment giant, has been using rapid prototyping (RP) for about a decade, and is now finishing a wider examination of its entire product development process. Deere is seeking to cut development time by as much as 50 percent, and is looking at how the different prototyping techniques can help that along. Using solid modeling software, as Deere did, is critical for engineering teams wishing to use RP technology. Deere has expended considerable effort recently developing a new product-delivery process (PDP). Such processes can be difficult to hammer out and then follow faithfully, especially in today’s work environment of lean staffs and greater profit pressure. Although RP materials have improved significantly since the first stereolithography machine came into use a little over 10 years ago, none of the current materials to date have the durability required for use on John Deere products sold to customers.

Abstract:

Mechanical harvesting systems for processed blueberries (Vaccinium spp.) are available. However, low harvest efficiency and high fruit damage have limited the use of mechanical harvesters for picking blueberries for fresh market to specific cultivars under good weather conditions. New harvesting technology for fresh-market blueberries is needed. The V45 harvester was developed by the U.S. Department of Agriculture in 1994 to harvest fresh-market-quality northern highbush (V. corymbosum) blueberries in Michigan. The current study was performed in Georgia to evaluate the V45 harvester on specially pruned rabbiteye blueberry [V. virgatum (syn. V. ashei)] and southern highbush blueberry (V. darrowi × V. corymbosum) and included analysis of harvest efficiency and fruit quality (percent blue fruit, percent bloom, percent split skin, and internal bruise damage). Six-year-old, 6- to 8-ft-tall ‘Brightwell’ and ‘Powderblue’ rabbiteye blueberry plants were winter pruned to remove vertically growing and overarching canes in the center of the bush in Jan. 2004 and Feb. 2005 respectively. Three-year-old, 3- to 5-ft-tall ‘FL 86-19’ and ‘Star’ southern highbush blueberry plants were similarly pruned in summer (June 2004) or in winter (Feb. 2005). Pruning removed an estimated 30% to 50% of the canopy and opened the middle, resulting in V-shaped plants in both rabbiteye and southern highbush blueberries. Yield of winter-pruned ‘Brightwell’ rabbiteye blueberry was lower compared with unpruned plants during both years, but winter-pruned ‘Powderblue’ rabbiteye blueberry plants produced as much as unpruned plants in 2005. In ‘FL 86-19’ southern highbush blueberry, plants that were summer pruned in June 2004 produced as much as unpruned plants in 2005, but plants that were winter pruned in Feb. 2005 had lower yields than unpruned plants in 2005. The V45 harvester caused little cane damage on pruned blueberry plants. In rabbiteye blueberries, internal fruit damage and skin splitting was less in V45-harvested fruit than in fruit harvested by a sway harvester and nearly that of hand-harvested fruit. However, in ‘FL 86-19’ southern highbush blueberry, the V45 harvester detached a lower percentage of blue fruit and excessive amounts of immature and stemmed fruit. These findings suggest that the V45 harvester has the potential to harvest some rabbiteye blueberry cultivars mechanically with fruit quality approaching that of hand-harvested fruit.

Abstract:

AbstractOn-farm field demonstrations provide a useful method of technology transfer for researchers and extension specialists, and the proponents of alternative agriculture have adopted on-farm experimentation as an important means to establish the value of sustainable methods. For on-farm research long narrow strips harvested by machine are often employed in place of small hand-harvested plots commonly used at research facilities. The use of this approach, however, could bring the methodology into question if field variation should make determination of statistical differences difficult. Analysis of harvest data from ten irrigated and four dryland site-years for small hand-harvested corn plots and for machine-harvested long narrow strips was conducted to determine the impact of sampling method upon experimental variation. Analyses of variance indicated that six of the ten machine-harvested irrigated sites had significant yield response to applied nitrogen while only one of the ten hand-harvested sites exhibited significant nitrogen effects (P ≤ 0.10). The difference in statistical precision was not a result of increased range in yields, but rather of more consistent yields for each treatment. An economic analysis was performed, and the results indicated that optimum nitrogen rates depended on corn and nitrogen price ratios. When 1989 corn and nitrogen prices were used, the calculated marginal profit levels between the reduced nitrogen and recommended nitrogen rate ranged from $8.92 to -$8.14 per ha. For the irrigated sites, when experimental variation (F-test of total sum of squares) was compared by harvest method, hand harvest had significantly greater variation than machine harvest in five experiments. Machine harvest was significantly more variable in one comparison. Coefficients of variation for machine harvest were less than for hand harvest in nine of ten irrigated experiments. For the dryland sites, differences between harvest methods were significant in one of four experiments. These data suggest that under certain conditions machine-harvested long narrow strips provide more accurate estimates of treatment differences than do small hand-harvested plots despite potential differences in soil texture, soil fertility, or available soil water.

Abstract:

In recent years area for cultivation of Melissa officinalis is ranged around 40 ha. Low production could be also caused by less intensive use of machinery. Aerial parts could be fully harvested by mechanisation, but in case of small growers using of special machinery is not economic. The majority of growers harvest manually and this type of harvest represents up to 80% of the costs associated with the cultivation. The less expensive alternative of harvest by a hedge trimmer is evaluated in this article. The goal is to compare two ways of harvest (manual harvest and hedge trimmer harvest) of lemon balm aerial parts in production practise. According to results of experiments were calculated and determined boundaries of effective use of hedge trimmer in production of lemon balm in comparision to manual harvest and fully mechanised harvest. Obtained data shown an increase of harvest performance in case of hedge trimmer (0.0425–0.0525 ha.hr−1) compared to manual harvest (0.0185–0.0216 ha.hr−1). According to calculations, we can say that effective use of hedge trimmer (including purchase price) is from 0.37 ha at planting surface and 0.48 ha at planting rows. Results could also be used for other MAP crops with similar harvest technology as for lemon balm (for example Mentha spp., Origanum spp., Achillea spp.).

Abstract:

Production and harvesting systems for processing vegetables have been highly mechanized, however, field efficiencies are generally low, and high field losses and fruit damage continue to limit profits for several crops. By comparison, the number of fresh market crops currently machine harvested is small, and research to develop new harvesting technology for these crops is limited. Current mechanization research includes improvements to existing production systems, development of harvesters for crops currently hand-harvested, and the integration of new technologies into current (and future) production systems. Mechanical harvester-based production systems are evolving that reduce field losses and fruit damage, improve recovery, and decrease the foreign materials in the harvested product. However, improved cultural production systems and crop varieties that are adapted for once-over machine harvest are needed. An integrated approach in which crop characteristics along with planting, cultivating, and harvesting techniques are considered will be necessary to develop profitable and highly efficient alternatives to hand-harvest production. The integration of new technologies including differential global positioning systems (DGPS), automatic machine guidance, and computer-based vision systems offers significant performance benefits, and is a substantial component of current vegetable production and harvesting research in the U.S. In time, as the costs of these technologies decline, commercial adoption of these new methods is expected to increase.

Abstract:

Human power which is relied on every harvest season becomes a big concern for farmers. Farmers in Ajibaho Village, Dusun VII Tanjung Marolan still utilize a simple equipment with human power to harvest rice. Some processes of harvest require longer time. It is started from cutting rice stalks, collecting rice stalks, and threshing rice by hitting it on a drum to thresh the rice from the stalks. After that, the rice was collected, put into white sack, and delivered to houses. This condition also depends on the weather which becomes longer when it is rain or sunny. A simple technology which uses thresher can be a good solution to achieve an efficiency of harvest process specially for the threshing process. The application of thresher machine is able to give a positive impact to increase harvest, to decrease daily cost, and to effectuate harvest process

Abstract. The U.S. apple industry, which generated more than $2.7 billion in revenue at the farm gate in 2013, is facing critical challenges with decreased availability of labor and increased labor and production costs. To address these challenges, a self-propelled apple harvest and in-field sorting machine is being developed in our laboratory. This article reports on the economic evaluation of this prototype machine by considering machine cost (annual ownership and operating costs), harvest productivity increase (including that due to decreased occupational injuries), and cost savings in postharvest storage and packing resulting from in-field sorting of fresh market quality apples from processing apples for both fresh apple growers and processing apple growers. The economic evaluation was conducted based on the assumptions that the machine increases harvest productivity by 43% to 63% and operates for 360 h during the harvest season. For fresh apple orchards with processing apple incidences of 5% to 15%, the net annual benefits that would accrue from owning one machine range from $13,500 to $78,400 when the machine price is between $100,000 and $160,000. For processing apple orchards with processing apple incidences of 80% to 90% and the same machine price range, the net annual benefits that would accrue from owning one machine range from $23,900 to $81,700. Overall, the benefits gained from in-field sorting outweigh those from the harvest productivity increase, and integration of the harvest-assist and in-field sorting functions is more beneficial to apple growers. This technology will help the U.S. apple industry improve labor productivity and reduce production costs, and thus it looks promising for commercialization. Keywords: Apples, Economic evaluation, Harvest-assist, In-field sorting, Machinery system, Occupational injuries.

Abstract:

The aim of this write up is to explore technological developments in the area of post-harvest grain storage techniques. Post-harvest losses occur between harvest and the moment of human consumption. They include on-farm losses, such as when grain is threshed, winnowed, and dried, as well as losses along the chain during transportation, storage, and processing. Use of traditional grain storage facilities such as cribs, improved rhombus, and brick bins are ineffective against mold and insects already present in the grain before storage. While plastic bins reduce insect pests’ infestation, Purdue Improved crop storage bags and wooden silo were proved to be a viable management tool for preventing aflatoxin accumulation in storage and moisture migration. The metal silo still remains an effective grain storage technology for reducing post-harvest insect and pathogen losses if the challenges of moisture and temperature can be adequately managed. An effective grain storage technology would be the ones that can sustain quality of grain stored for a long period (≥5 years), durable, cost-effective, and be managed scientifically, possibly by computer-aided grain management system.

Abstract:

The instant rising demand of plant-based drugs is unfortunately creating heavy pressure on some selected high-value medicinal plant population in the wild. The safety, quality and efficacy of these products have become a major concern for health authorities and the consumers. Unavailability of proper production technology and suitable area of cultivation, post-harvest processing, market constraints and low economic returns as compared to major cereal crops, are the main problems in cultivation of these herbs and spices. Safe, efficacious and a high-quality product showing batch to batch consistency can be maintained by following harvesting and post harvesting standard guidelines for MAPs (Medicinal & Aromatic Plants).

Abstract:

Technological audit of dairy farms in the Novosibirsk region revealed the main problems of keeping, feeding and breeding animals, causing a decrease in production efficiency. Only about 30 % of enterprises with a cow yield of less than 7000 kg per lactation harvest high quality feed. At the same time, on average for three years from 24 to 68 % of the harvested forages were classified as non-class according to the analyzed samples from 15 districts of the region. More than 60 % of the surveyed farms are characterized by poor animal hygiene. Conducted late or not carried out functional hoof trimming. The share of enterprises using only artificial insemination of cows is low, the frequency of gynecological diseases is high. The technology of young growth is not observed. Almost all indicators of such enterprises are significantly different from the reference (with milk yield of cows over 7000 kg). Critical to achieving such productivity are technological discipline, including climate, proper feeding and milking, availability of qualified specialists and herd management system.

Abstract:

RF Energy Harvesting is a technology that harvest RF ambient energy from the wearable devices. One of wearable devices that can act as a source is LoRa end device. LoRa (Long Range Access) is part of Low Power Wide Area Network (LPWAN) which operate in unlicensed frequency (ISM). As a technology of wireless network, end devices of LoRa will be taken in remote area that hardly to access. End device LoRa acts as a transceiver that transmits and receives data from the gateway. As a transceiver, the LoRa end device requires energy availability. In remote area, RF ambient energy from the LoRa end device can be utilized as a source of RF energy that can be harvested and stored This paper discusses how to harvest the RF ambient energy emitted by the LoRa end device using the microstrip antenna as the receiver and the voltage multiplier as both a rectifier and a voltage multiplier. The energy harvested from one end device and stored temporarily in the capacitor is 163pJ with a distance 11 cm from the source. This harvested energy can be stored on battery or capasitor bank to be used in future

Abstract:

A major challenge for implantable medical systems is the inclusion or reliable delivery of electrical power. We use ultrasound to deliver mechanical energy through skin and liquids and demonstrate a thin implantable vibrating triboelectric generator able to effectively harvest it. The ultrasound can induce micrometer-scale displacement of a polymer thin membrane to generate electrical energy through contact electrification. We recharge a lithium-ion battery at a rate of 166 microcoulombs per second in water. The voltage and current generated ex vivo by ultrasound energy transfer reached 2.4 volts and 156 microamps under porcine tissue. These findings show that a capacitive triboelectric electret is the first technology able to compete with piezoelectricity to harvest ultrasound in vivo and to power medical implants.

Abstract:

Rakiura Maori (a tribe of indigenous people in New Zealand) continue a centuries-old customary use of Sooty Shearwater (Puffinus griseus, titi, muttonbird) chicks from islands adjacent to Rakiura (Stewart Island). Some muttonbirders pluck chicks by hand, while others have recently changed to a plucking machine. We compared traditional and modern processing methods to see if new technology stands to increase the efficiency, size and cost effectiveness of harvest. On average, chicks were plucked 6 seconds quicker with a machine, which could potentially increase the catch by up to 4%. Innovation by using wax rather than water to remove down left after plucking saved muttonbirders 29–97 minutes per day, potentially allowing up to a 15% increase in the number of chicks harvested. Both wax and plucking machines increased costs, which led to a modest financial gain from using wax, but a net loss from using a plucking machine. Modern technologies have been introduced mainly for convenience and to ease labour in this customary use of wildlife. New technology may erode traditional skills, but does not necessarily pose a risk to the sustainability of a resource. Financial investment in harvest technologies might provide an incentive to increase harvest levels, but could equally provide an incentive to manage for sustainable use. Preservation lobbies are not justified in presuming that new technologies will always threaten wildlife traditionally used by indigenous people.
