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 role of agriculture in the economic development of this country is still very important, besides being a fuel provider, this sector also contributes significantly to the development of workforce which is expected to have an increase in the change in the level of poverty. The Ministry of Agriculture has a vision and mission in alleviating poverty by rolling out various forms of programs to increase capital for farmers. Farmers who have developed their level of education, improved changes in the economic and political structure, began to understand to form a farmer group that had the goal of obtaining and obtaining mutual assistance included in the agricultural program of the government, such as the UPSUS Pajale Program. Farmers who are members of farmer groups will strengthen the ability of their groups to manage and channel the Pajale UPSUS Program assistance that requires improving farm safety consisting of indicators; the role of members of farmer groups, suitability of group services, collectivity, and resolution of local wisdom that still requires in its farming activities. The success of farmer groups can not be separated from social capital which is the main foundation that must be owned by farmers as group members. Mangkuprawira (2010) describes the support of social capital in farmers such as social norms, mutual trust, networking, cooperation, mutual relations, participation, and commitment that will be directly connected to the success of the UPSUS Pajale (soybean) program being rolled out by the government, and seen from three indicators namely; successful output, successful results, and successful benefits. The UPSB Pajale Program in East Lampung Regency is held from February to March 2019. The data used are primary and secondary data with the Mix-method research method. The sampling technique used was the Proportional Stratified Random Sampling with a total sample of 140 farmers who were members of a farmer group receiving the 2017 UPSUS Pajale Kedelai Program in East Lampung Regency. Data processing is done qualitatively and quantitatively. Data is arranged qualitatively using descriptive analysis, while quantitative data is processed using Structural Equation Modeling (SEM) analysis, which uses the LISREL 8.80 program. The results showed the value of R2 = 0.71, which means that the second variable namely Farmer Institutional Performance and the Existence of Farmer Social Capital contributed 71 percent and was significant to the Success of the UPSUS Pajale Program in East Lampung Regency.Keywords: Farming Institution, Existence of Social Capital, and UPSUS Pajale Program

Abstract This study aims to analyze the level of farmer empowerment in carrying out farming activities as the main livelihood and its impact on farm income during the Covid-19 pandemic. The research was conducted online by distributing questionnaires in the form of google form in various affordable areas. There were 113 responses obtained by returning the google form on time. The three regions that sent the most responses were farmers in Ambon City, West Seram Regency, and Central Maluku Regency. After analyzing using qualitative descriptive analysis, the results showed that the level of farmer empowerment during the Covid-19 pandemic decreased, especially in terms of marketing of crop products for fruit and vegetable commodities, while for food commodities such as rice tended to be stable. This has an impact on farm productivity and income. The main factor causing a decrease in the level of farmer empowerment is the decreasing purchasing power of the community during the Covid pandemic19; Accessibility of farmers to markets is difficult, there are even times when farmers cannot go to the market due to large-scale social restrictions, the frequency of presence of collectors is reduced, access to plant production facilities is hampered unlike before the Covid pandemic19. This condition requires serious attention from the government so that farmers do not experience difficulties in marketing agricultural products and can maintain the stability of farm income. The solution at the farmer level is to form farmer groups so that the marketing of farm products and the fulfillment of plant production facilities can be done through farmer groups.

Fertilisation in grain corn production is an important stage that must be done properly in terms of the amount of fertiliser used to reduce wastage and ensure crop growth. A fertilising implement brand Gasprado, was calibrated and evaluated for its performance to apply urea to grain corn crops at MARDI Seberang Perai, Pulau Pinang. Calibration was conducted to set the right metering for the device's opening to drop  urea that  meets the application rate of 130kg/ha. This was done by measuring the amount of urea dropped for a particular setting and distance. The machine has four metering devices which were labelled as MD1, MD2, MD3 and MD4. Additionally, the fertiliser applicator also comes with spring tine cultivating devices. The implement was tested for fertilising 56 rows of grain corn in the distance of 62 m long. The times taken for the tractor to finish four rows per run along the 62-m distance and to turn at the headland were recorded to evaluate the performance. The implement's metering devices MD1, MD2, MD3 and MD4 were calibrated at setting scales of B-1.5, B-0, B-0 and B-0, respectively that gave the urea application rate of 133 kg/ha, which was the nearest rate to the recommendation. The average working speed of the operation was at 4.08 km/h with the theoretical field capacity to be at 1.224 ha/h. Meanwhile, the machine's effective field capacity was 0.5208 ha/h, which had a field efficiency of 42.5 % for the particular farm design. The use of machine can speed up the operation of applying fertiliser to the grain corn crop but the performance is dependent on the farm layout.

Deep placement of super granular urea is very laborious and time consuming work for manually operation. To overcome the human stress and drudgery to place the super granular urea, a low cost manually operated pull type 2- rows granular urea applicator (GUA) was designed and developed in the department of Farm Power and Machinery, Bangladesh Agricultural University, Mymensingh. The performance of machine was done in agronomy field of Bangladesh Agricultural University. The effective field capacity was 0.11 ha/hr at a forward speed of 1.78 km/hr and 78.89 % field efficiency of developed granular urea applicator. The average distance between two dropped granular urea (GU) from left hopper & right hopper were 40.64 cm and 40.89 cm respectively. The average missing rate of GU dropped during field operation was 1.65% for granular urea size of 2.83 gm. The depth of granular urea placement was 7-10 cm in puddle field. The pulling force and draft of the developed applicator were varied between 5-11 kg and 3-6.62 kg respectively. The draft power was 0.027 kW for 55.38 N pulling force at 1.78 km/hr speed. The application rate of the GUA was 170 kg/ha. The results of field and laboratory test of the developed applicator were better in comparison to other models of GUA. The operational cost of the applicator is 390 Tk/ha which is lower than 22.16% of BARI made push type GUA and 53% lower than the manually placement of GU. Average grain yield was highest (5234 kg/ha) when granular urea were applied by the developed applicator and followed by GU applied by BRRI made push type GUA (5213 kg/ha) and GU applied by manually (5209 kg/ha). The highest straw yield (6787 kg/ha) was obtained when GU applied by manually. However the differences of grain yields and straw yields were not significantly difference for applying GU by the applicators and manually operation. The manufacturing cost of the applicator is only Tk.6000. The weight and the drawbar power of the applicator were 15 kg and 0.03 kW respectively. Therefore one person (man or women) is enough to pull the machine. Overall performance of the applicator was found quite satisfactory. For this reason, the applicator may be introduced in Bangladesh to apply super granular urea. DOI: http://dx.doi.org/10.3329/jbau.v12i1.21414 J. Bangladesh Agril. Univ. 12(1): 211-220, June 2014

The conventional sowing method of onion seeds offers great wastage and laborious. This study aimed to develop a pull-type onion sowing machine for seedbed to optimize the sowing of seeds, reduce labor cost, yields better quality onion seedlings, and increases income of onion farmers. The machine was tested and evaluated, in comparison with manual sowing of onion seeds, in terms of seed delivery rate, effective field capacity, field efficiency, seeding efficiency and drawbar power. The cost of sowing seeds using the machine was also determined. Results indicated that machine’s delivery rate was significantly reduced to 5.33 g/m2 from 11.35 g/m2 This resulted to reduction in the quantity of seeds sown for a one-hectare onion production area by about 4-5 cams (1.6 to 2 kg). Machine’s field capacity (375.45 m2/h) was higher than of manual sowing (25.51 m2/h). Field efficiency at 86.94% is higher than 60% threshold given by PAES [3]. The seeding efficiency of 89.70% was statistically the same with three seeds per 25 mm hill spacing. The drawbar power was found out to be 0.15 5kW. The cost of the machine is $1,666.67 with a break-even quantity of 9,226.9 m2 or 138.11 cans of onion seeds in 0.62 years.
