Konkan is the coastal part of Maharashtra between Western Ghat and Arabian seacoast. Rice is a major crop grown over 3.86 lakh hectares. Stripper harvesting technology, which strips only seeds and keeps straw erect-ed in the field present bright prospect for the development of small, light, efficient mechanism by reducing number of operation with increased capacity and lesser power compared to conventional cutter bar combine harvester. The big machines like combine harvester and high capacity threshers for harvesting and threshing have limitations. A proto-type of paddy stripper harvester was developed considering the limitation of Konkan like small, fragmented land, hilly, terrace farming and high rainfall. It consisted of stripping mechanism, grain tank, hydraulic system, steering system, gear box, engine, cage wheel and chassis. The arrangement of V-belt and set of pulleys were made to transmit power from gear box to stripper rotor. The effect of forward speed and peripheral speed on shattered and un-stripped grain loss was studied. The shattered grain loss was decreased with increase in forward speed whereas decreased initially and then increased with increase in peripheral speed. The un-stripped grain loss was decreased with increase in forward and peripheral speed. The performance of the developed prototype was found better at forward speed of 2.25 km/h and peripheral speed of 19.78 m/s. During final testing of prototype, shattered and un-stripped grain loss was found 5.95 and 1.89 %, respectively. The average field capacity and field efficiency of paddy stripper harvester machine was found 0.14 ha/h and 69.38 per cent respectively.

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.

Crop Parameters

Pigeon-pea is very thick and woody stem crop, therefore the harvesting and threshing of this crop is a drudgery and time consuming. At present in India pigeon-pea is harvested manually with sickle and after that the crop is left in the field in the form of heaps for 7-10 days for sun drying. After sun drying the crop is threshed with suitable thresher or beating with stick etc. Lack of mechanization of harvesting and threshing operation is one of the limitations to the increase production and productivity of pigeon-pea. Therefore, the present study was aimed at optimizing operational and crop parameters influencing the mechanized harvesting and threshing of pigeon-pea crop with combine harvester. PAU-881, AL-1856, AL-1817 and AL-1811 of extra-short duration pigeon-pea were selected for the study. The moisture content of crop and grain varied from 38 to 48% and 22 to 25% on wet basis respectively for crop varieties AL-1817 and AL-1811 and it was 48 to 53% and 24 to 27% on wet basis respectively for crop varieties PAU-881 and AL-1856. Concave clearance was kept as 16 mm at front side and 7 mm from rear side. Threshing efficiency was more than 98% at cylinder peripheral speed of 26.61 m/s and 34.85 m/s in all varieties except PAU-881. The percent grain breakage was higher for higher cylinder peripheral speed and lower for higher forward speed. The grain damage was below 1% for 23.85m/s, 26.61 m/s and 34.85 m/s cylinder peripheral speed in all crop varieties except AL-1811. The optimum values of peripheral velocity and forward speed of combine harvester harvesting pigeon-pea were 26.61 m/s and 2.0 km/h for all selected varieties.

Field Efficiency

A mid-size combine harvester with 2.76 m reaping width and 103.53 hp engine output has been employed in grain corn production, especially by small-scale grain corn farmers. This study attempted to determine field performances of a typical mid-size combine harvester by measuring its effective field capacity (EFC), field efficiency (FE), fuel consumption (FC) and field machine index (FMI). Different types of energy inputs such as fuel, machinery, human, included direct, indirect, renewable and non-renewable energy involved in grain corn harvesting were also measured. The field measurements were carried out in 3 ha of grain corn farm, under similar field conditions using a typical mid-size combine harvester. The average values of EFC, FE, FC and FMI for the mid-size combine harvester were found to be 0.23 ha/h, 34.97%, 37.25 lit/ha and 0.91, respectively. The average equivalent energy values of fuel, machinery and human energy were 1780.70 MJ/ha, 587.73 MJ/ha and 8.53 MJ/ha, respectively. The average values of the direct and indirect energy were 1789.23 MJ/ha and 587.73 MJ/ha, respectively. The average values of renewable and non-renewable energy were recorded at 8.53 MJ/ha and 2368.42 MJ/ha, respectively. The mid-size combine harvester investigated in this study exhibited good field performance characteristic using a reasonable amount of energy consumption as compared to harvesting operation for other grain crops. From the results, it can be concluded that good practice in harvesting operation could improve field performance, and minimise operational costs and energy consumption.

Mechanization is a vital issue to modernize agriculture. The entrepreneurship development is imperative to provide service to the farmers at an affordable price, especially in haor areas. The study was conceived to estimate the combine harvester's rental charge and payback period. Data were collected from 86 rice fields harvested by a whole-feed combine harvester (Model: Zoomlion) in Mithamain upazila under the Kishoreganj district representing haor area of Bangladesh. Land size, operational time, loss time, repair time, idle time, daily area coverage and constraints of harvester machine were also recorded to predict the business viability of combine harvester. The rental charge and payback period was calculated following standard protocol to make business venture profitable. The perception of farmers regarding the prospect of using combine harvester in harvesting has been recorded through personal interviews. The field capacity of combine harvester was observed as 0.20 ha hr-1. Field efficiency of combine harvester depended on the land size. The daily area coverage can be increased after careful selection of the plots. Fuel consumption was found 4.18 l ha-1. Operational consolidation is the best approach to reduce the time of movement resulting in increased daily area coverage. Seasonal use of combine harvester in one locality of the study area was observed for 22 days. The rental charge of the machine was estimated as 10,000 Tk ha-1 and payback period was 3.5 years for the area coverage of 40 ha rice fields. Farmers would be able to save 40% harvesting cost for the rental charge of Tk 10,000 ha-1. Combine harvester rental service has emerged as a viable business model in the haor basin. Whole-feed (Zoomlion model) combine harvester appeared as an effective, economical, and labour-saving harvesting machine in the haor region land tenure system. Bangladesh Rice j. 2019, 23(2): 65-75

The Impact

The growing demand in food and non-food industries for camelina oil is driving the interest of farmers and contractors in investing in such feedstock. Nonetheless, the cost, performance and critical aspects related to the harvesting stage are still not properly investigated. In the present study, an ad-hoc test was performed in Spain in order to fulfill this gap. The results support the hypothesis to harvest camelina seeds with the same combine harvester used for cereal harvesting without further investment. Theoretical field capacity (TFC), effective field capacity (EFC), material capacity (MC), and field efficiency (FE) were 4.34 ha h−1, 4.22 ha h−1, 4.66 Mg h−1 FM, and 97.24%, respectively. The harvesting cost was estimated in 48.51 € ha−1. Approximately, the seed loss of 0.057 ± 0.028 Mg ha−1 FM was due to the impact of the combine harvester header and dehiscence of pods, whilst 0.036 ± 0.006 Mg ha−1 FM of seeds were lost due to inefficiency of the threshing system of the combine harvester. Adjustment of the working speed of the combine and the rotation speed of the reel may help to reduce such loss.

Floriculture is an age-old farming activity in India having immense potential for generating selfemployment and income to farmers. However, the cost of cultivation of flower is high as compared to cereal crop. Level of mechanization for different field operations is one but foremost reason for the higher cost of cultivation. As most of the Indian farmers are marginal and small, a need for manually operated gladiolus planter was felt. The geometric properties of gladiolus corm were determined for designing the seed metering system and seed hopper of the planter. The planter was evaluated in the field when pulled by two persons as a power source and guided by a person. The coefficient of variation and highest deviation from the mean spacing was observed as 12.93% and 2.65cm respectively. The maximum coefficient of uniformity of 90.59% was observed for a nominal corm spacing of 15cm at 0.56 kmh-1 forward speed. An average MISS percentage was observed as 2.65 and 2.25 for nominal corm spacing of 15 and 20 cm. The multiple index was zero for two levels corm spacing and forward speed of operation. The QFI was found in the range of 97.2 and 97.9 percent. The average field capacity of the planter was observed as 0.02 hah-1.The average draft requirement of the planter was found as 821 ± 50.3 N.
