Development and Performance Analysis of Low Cost Combined Harvester for Rabi Crops CIGR Journal
JAWLEKAR, SAGAR BHASKARRAO; SHELARE, SAGAR DNYANESHWAR.
The number of farmers in India especially in Vidarbha Maharashtra is decreasing due to the continuous loss in cultivation. Harvesting technique is one of the primary reasons behind losses. Manual harvesting is dreary and tedious. To overcome this issue harvesting machines are accessible yet these are substantial and costly. Since farmers with small lands have constrained utilization and furthermore harvesting is done hardly twice or thrice in a year, so it is difficult to afford expensive machines. So, there is a need to develop a small scale and cost-efficient harvesting machine which is...

ESTIMATED COSTS OF SOLDIER AND COMBINE SUGARCANE HARVESTING SYSTEMS IN LOUISIANA AgEcon
Salassi, Michael E.; Champagne, Lonnie P..
Soldier (wholestalk) harvesting of sugarcane has been the predominant method of harvesting sugarcane in Louisiana for many years. With the short harvesting season and frequently wet harvesting conditions found in the state, this type of harvesting system has proven to be a very flexible and suitable system. Combine (billet) harvesters have the ability to recover more of the sugarcane in the field, compared to soldier harvesters, particularly in fields with lodged sugarcane. This report quantifies some of the differences in machinery requirements, performance rates, and estimated costs of...

Cost/Benefit of Abscission Registration for Citrus Mechanical Harvesting AgEcon
Blanco, German; Roka, Fritz M..
The Florida Department of Citrus (DOC) is spending public funds to register an abscission agent compound (CMNP) with the U.S. EPA as part of its effort to enhance the private benefits associated with citrus mechanical harvesting. An abscission agent application should allow existing harvesting equipment to operate through the entire late season orange harvesting period. When estimating costs and benefits through 2018, the net present value of mechanically harvesting 25,000 acres is between $60.8 and $79.9 million, depending on price, production, and fruit loss scenarios. For any of the scenarios considered, the discounted...

Evaluation the mechanical harvesting efficiency of olive with the application of fruit loosening spray CIGR Journal
Khdair, Adnan I.; Abu-Rumman, Ghaida; Khdair, Sawsan.
Abstract: Olive is harvested mainly by hand in the Mediterranean. This resulted in steady rising of harvesting cost due to shortage of skilled labors at harvesting time. Operation cost might be reduced and harvesting processes will be carried out on time if mechanical harvesters are used. In 2015 an experiment was performed to study the effects of mechanical harvester and use of loosening agent on harvesting productivity and efficiency. The experiment was conducted using randomized complete block with two regional olive varieties Nabali Rosie and Nabali. Harvesting productivity by hand...

Performance Assessment of Manual Rice Harvesting Methods under Farmer’s Field Conditions CIGR Journal
Amponsah, Shadrack Kwadwo; Addo, Ahmad; Djidohopkin, Ella; Olaye, Romaric Biaou.
A better understanding of field performances for traditional harvesting methods and tools is essential in facilitating future improvement on design and overall efficiency. Performance of different manual harvesting tools and methods was evaluated under farmer’s field conditions for IR841 and Nerica L20 rice varieties in Benin. Results from evaluation showed that an average of 84 to 161 man-hours was required to thresh a hectare of rice field using either the threshing by impact “bambam” or bag beating method.  Less time was however required to thresh IR841 than Nerica L20 varieties, irrespective of manual threshing method used. Similarly, between 58 to 95 man-hours was required to harvest...

Effect of cereal stubble management on the combine harvester performance and energy requirements CIGR Journal
Jokiniemi, Heikki Tapani.
Combine harvesting is one of the most energy consuming field operations in arable farming. The power demand of combine harvester depends strongly on the mass flow through the machine, and one approach to reduce the energy consumption is thus increasing the stubble height in harvesting. In this study, the energy saving possibilities by increased stubble height and different straw management in cereal harvesting were examined. In addition to combine harvesting, the mulching of the tall stubble with a tractor powered rotary mower after the harvest was investigated. The results indicated an energy saving of 22%–24% in combine...

Water harvesting options in the drylands at different spatial scales AgEcon
Ali, Akhtar; Oweis, Theib; Rashid, Mohammad; El-Naggar, Sobhi; Aal, Atef Abdul.
The effect of spatial-scale variations on water harvesting has been evaluated at micro-catchment, hillside/farm, and watershed (=catchment) scales in three relatively dry environments in Syria, Pakistan and Egypt. Micro-catchment water harvesting captures localized runoff only through independent micro-catchment systems and is not influenced by hill slope runoff and stream flows. In Syria, it was found that only a fraction of total runoff from a catchment is collected, with no significant effect on water supply downstream. Therefore, it is less sensitive to spatial-scale variations (rainfall, topography, soils) and it is less likely to create upstream-downstream water-use conflicts....

SIMULATION OF HARVESTING ASPARAGUS: MECHANICAL VS MANUAL AgEcon
Cembali, Tiziano; Folwell, Raymond J.; Ball, Trent.
Asparagus harvesting methods and strategies have remained unchanged since inception in Washington. A bioeconomic model was developed to determine the profit optimizing frequency of harvesting for manual and mechanical harvesting techniques. The mechanical harvester is economically viable if the harvester cuts 72.3 percent and 73.55 percent of what a hand crew would cut for process and fresh utilization, respectively. The results indicate that decreasing the frequency of harvest increases profit for asparagus used in processing. This research is the first attempt to address the problem of asparagus harvesting with a...

An evolutionary economic perspective on technical change and adjustment in cane harvesting systems in the Australian sugar industry AgEcon
Brennan, Lisa E.; Wegener, Malcolm K..
Australian sugar-producing regions have differed in terms of the extent and rate of incorporation of new technology into harvesting systems. The Mackay sugar industry has lagged behind most other sugar-producing regions in this regard. The reasons for this are addressed by invoking an evolutionary economics perspective. The development of harvesting systems, and the role of technology in shaping them, is mapped and interpreted using the concept of path dependency. Key events in the evolution of harvesting systems are identified, which show how the past has shaped the regional development of harvesting systems. From an...

Organisation and profit-sharing in mechanised sugarcane harvesting: Is Australia's experience relevant to China? CIGR Journal
Wegener, Malcolm.
China now grows about 1.5 million hectares of sugarcane and is the third largest sugar producer in the world after Brazil and India.  Almost all Chinese sugarcane is still harvested by hand but labour in countryside areas has become more expensive and difficult to recruit.  The sugar mills prefer to crush the cleaner cane that manual harvesting delivers and some mills, in areas where mechanical harvesting capacity has increased in recent years, have imposed restrictions on the quantity of machine cut cane that can be delivered each day.  In the longer term, it is inevitable that the mills will accept a greater proportion of machine harvested cane.   It is therefore important that an...

Experimental comparison of combine performance with two harvesting methods: stripper header and conventional header CIGR Journal
Mirnezami, Seyed Vahid; Chegini, Gholamreza.
Residual straw status on the field after harvesting was one of the important obstacles in using stripper header in Iran. In this work, combine performance studied with two type headers, conventional and stripper in wheat farm. Residual stems after harvesting collected, baled, and two methods were compared. The results showed that fuel consumption in the stripper header was 5.68 L/ha less than the conventional header. Combines with stripper header harvested 1500 m2 more than the conventional header in each hour. Stripper header in comparison with the conventional had 21% harvesting efficiency and 840 kg/h field performance which harvested more wheat.
