For agricultural machinery management the actually reached machines capacity has a considerable importance. The data recorded by GPS monitoring enable to correct machines work productivity under concrete operational conditions. Assessment of machine aggregates operation records has proved effect of the operational factors onto operational efficiency reached on particular plots. The theoretical efficiency given by exploitation characteristics of machines has decreased effect of higher share of non-productive travels within small and irregular plots almost by 25%. In this paper we are dealing with searching for correlation between field speed and travelled unit path and defined classes of size, length and plot shape. The resulting knowledge of field efficiency on plots properties will enable to make more accurate the machines planned operation.

Cassava is a major source of food and raw material for domestic and industrial uses in Nigeria. Consequently, the technologies involved in its cultivation from planting to harvesting require proper development. This paper reports the development of a labour-saving technology for harvesting cassava using standard procedures for designing soil engaging implements. Locally available materials were also used in the fabrication of the harvester. Results of trial tests indicate a digging efficiency of 58.9%, fuel consumption of 16 l/ha, field capacity of 0.11 ha/hr, field efficiency of 67.9% and root damage of 43.03%. The total cost of fabricating the machine was 184,000 naira only. Further tests under various soil and operational conditions for improvement and optimization were recommended for the purpose of patenting for commercialization.

Steep terrain harvesting can only be implemented by a limited set of operational alternatives; therefore, it is important to be efficient in such conditions, in order to avoid incurring high costs. Harvesting abiotically-disturbed forests (salvage harvests caused by wet snow), which is becoming common these days, can significantly impact the operational efficiency of extraction operations. This study was implemented in order to evaluate the performance of truck-mounted uphill cable yarding operations in salvage logging deployed in coniferous stands. A time study was used to estimate the productivity and yarding costs, and predictive models were developed in order to relate the time consumption and productivity to the relevant operational factors, including the degree of wood damage. The average operational conditions were characterized by an extraction distance of 101 m and a lateral yarding distance of 18 m, resulting in a productivity rate of 20.1 m3 h−1. In response to different kind of delays, the productivity rate decreased to 12.8 m3 h−1. Under the prevailing conditions, lateral yarding accounted for 32% of the gross work cycle time, and for 50% of the delay-free work cycle time of the machine. Decreasing the lateral yarding distance and increasing the payload volume to the maximum capacity of the machine would eventually lead to a yarding productivity of close to 30 m3 per SMH (scheduled machine hour). The calculation of the gross costs of uphill yarding showed that the labor costs (35.7%) were slightly higher than the fixed costs (32.9%), and twice as high compared to the variable costs (17.7%). The remote control of the carriage, mechanical slack-pulling mechanisms, and radio-controlled chokers are just some of the improvements that would have led to increments in operational efficiency.

The agricultural operational holding in India is about 1.15 ha and 85.01 per cent belongs to marginal holdings (below 2 ha). This data shows an economic condition of the Indian farmer, which doesn’t allow him to adopt advanced agricultural machineries. Considering the situation of Indian farmer, we developed a prototype of three row self-propelled zero till direct seeded rice planter cum fertilizer applicator. This machine helps to plant a dry rice seed along with the fertilizer application with zero tillage condition. The machine includes inclined plate metering mechanism for seed; cup feed metering mechanism for fertilizer, seed cum fertilizer hopper, ground wheel, depth control wheels, inverted T furrow openers, 5 hp engine as a prime mover, power transmission system, adjustable handle, lever and rigid main frame to support all the parts and drive wheels. Machine is divided into two parts viz., prime mover part and planter cum fertilizer applicator part. Both parts can be separated from each other. The machine places the rice seed up to average depth of 25-40 mm and spacing between hills is observed to be 130-160 mm along with an average 20 cm of row spacing. The average field capacity at an average speed of 2.3 km.h-1 is observed to be 0.115 ha.h-1 for operating rice seeds. The field efficiency is observed to be 86.9 per cent. The operational cost is observed to be around 69.28 per cent less than the manual planting of rice seedling and also the man hour’s requirement is very less than the manual planting.

Harvesting is one of the major labor intensive works in rice cultivation. Appropriate harvesting machinery is urgently needed to reduce labor and production costs. Production cost of rice becomes high due to labor shortage and high wage rate during harvesting time. Techno-economic performance of Korean self-propelled reaper (KR), China self-propelled reaper (CR) and BRRI reaper (BR) were evaluated in order to identify the field constrains and problems of the reapers at Mithapukur of Rangpur, Bangladesh during Aman season of 2013. The actual field capacities of the KR, CR and BR were found 0.18, 0.17 and 0.15 ha h–1with the corresponding field efficiency of 55, 68 and 56%, respectively. The variation of field capacity among the models was due to turning time losses, weight of the reaper and operator’s skill. The fuel consumption of the reapers was 4.11, 2.61 and 8.39 l ha–1 for KR, CR and BR, respectively. The shattering loss of paddy harvesting was 1.66, 1.50 and 1.45% for KR, CR and BR, respectively. The break-even area of the reapers was 9.15, 7.82 and 8.43 ha yr-1 for KR, CR and BR, respectively. It is evident that the reaper could be used successfully as labor saving and user friendly technology to eliminate post-harvest problems in Bangladesh.J. Bangladesh Agril.

Weed control is one of the major problems in crop and vegetable production in Nigeria. Most of the peasant farmers use manual weeders in their cultivation, a process that is costly, labour intensive and time consuming. The process does not also give the farmer adequate returns to enable him breakeven. It is, therefore, necessary to design a weeding equipment which minimize the human effort and provide efficient work output for the peasant farmer. This study focus on designing, construction and evaluation of a hand-pushed weed control machine that would eliminate the challenges being faced by the farmer in weeding. Materials selected to suit the construction of the weeder are durable and locally available, easily replaced if damaged and at affordable cost. They include mild steel (3mm, 5mm), 30 mm circular (hollow) pipes, 10 mm diameter steel rod, and 40 cm pneumatic tyre. The developed weeding machine was evaluated in the experimental farm of IAR with impressive results. It works well in sandy loam soil of about 25.65% moisture content and requires less labour force compared to the manual hoe. It has about 84.7% weeding efficiency, 0.0129ha/hr effectivefield capacity, 0.019ha/hr theoretical field capacity and 68% field efficiency. The average cost of the weeding is N21, 000:00.

Cardoon seeds have been proved to thrive in the Mediterranean region, even under low input management and its biomass is suitable for several food and industrial uses. Despite that, a proper value chain has not been set properly and uncertainty still lays among producers and industries, particularly concerning the harvesting stage. The present study supports, via field trials, the hypothesis that cardoon seeds can be harvested using a conventional combine harvester equipped with the sunflower header. Theoretical field capacity (TFC), effective field capacity (EFC), and field efficiency (FE) were 2.36 ha h−1, 2.05 ha h−1, and 1.82 Mg h−1, respectively, while harvesting costs were calculated as 69.52 € ha−1. Seed loss was only 3.2% w/w of the potential seed yield. The machinery’s performance, costs, and seed loss are comparable with sunflower harvesting, underlying the possibility to use the available technology directly to harvest cardoon seeds.

The use of plastic mulch in agriculture is increasing day by day due for increasing crop yield. Mulch film are available in different types but plastic mulching requires less efforts. This paper highlights a new developed mulch laying machine for spreading of polyethylene black plastic mulch on soil. Animal drawn plastic mulch laying machine was developed at the SV College of Agricultural Engineering and Technology, IGKV, Raipur and was evaluated for its performance by conducting field trials. The average field capacity and average field efficiency was found to be 0.115 ha/h and 71% respectively. The average speed of operation was found 1.35 km/h for developed machine and 0.226 km/h for traditional method of mulch laying. The cost of operation was found to be Rs.1343/ha. Energy requirement of developed machine in mulch laying operation was found 187.34 MJ/ha it was found very less than the energy requirement 754.60 MJ/ha of traditional method of mulch laying. This machine will avoid the wages of labours used for laying plastic mulch and covers the plastic mulch with the soil on its either side edges. Using the mechanical system, the accuracy and ease during plastic laying was achieved.

Diante ao exposto, objetivou-se avaliar o desempenho operacional na semeadura de milho safrinha na Fazenda Chopim em Novo Mundo – MT.  Foram realizadas avaliações em três dias de semeadura em talhões de formatos distintos, um com formato trapezoidal e outro com formato irregular, ambos com topografia levemente inclinada. Foram coletados os tempos produtivos, de interrupções e o de preparo, além da distância percorrida. Para a condução do ensaio foi utilizado um trator BH180, marca Valtra, ano 2008 e uma semeadora da Tatu Marchesan, modelo Ultra Flex, de 28 linhas. Foram avaliadas a capacidade de campo teórica, efetiva, operacional e a eficiência de campo. O desempenho operacional do conjunto da Fazenda Chopim apresentou média de capacidade de campo efetiva igual a capacidade de campo teórica (12 ha h-1). A semeadura na Fazenda Chopim foi considerada eficiente, pois apresentou valores médios (65,66 %) dentro dos valores considerados eficientes pela literatura (50-75%).   Palavras-chave: eficiência, mecanização, conjunto trator-semeadora.   OPERATIONAL PERFORMANCE IN THE CORN SOWING IN THE DIRECT SOWING SYSTEM   ABSTRACT: The corn sowing is subject to factors that may affect the quality of the operation, mainly climatic factors that directly affect the soybean harvest and consequently the corn sowing, so it is necessary that both operations are efficient, ensuring the success of agricultural production. Faced with the above, aimed to evaluate the operating performance in sowing winter corn in Fazenda Chopim in Novo Mundo – MT. Evaluations were conducted in three days of sowing in plots of different shapes, one with a trapezoidal shape and the other with irregular shape, both with slightly inclined topography. The productive, interruption and preparation times were collected, in addition to the distance covered. A BH180 tractor, Valtra, 2008 and a Tatu Marchesan seeder, Ultra Flex model, 28 rows, was used to conduct the test. Theoretical, effective, operational field capacity and field efficiency was evaluated. The operational performance of the Fazenda Chopim set showed an average effective field capacity equal to the theoretical field capacity (12 ha h-1). Sowing at Fazenda Chopim was considered efficient, as it presented average values (65.66%) within the values considered efficient by the literature (50-75%).   Keywords: efficiency, mechanization, tractor-Seeder Set.
