Harvesting is one of the major problems encountered by tiger nut farmers in Nigeria. Manual harvesting system is the most commonly used method. This process is costly, labour intensive and time-consuming. The process does not also give farmers adequate returns to enable them to break even due to huge losses encountered. The objective of this study was to design, construct and evaluate a hand-pushed harvester that would eliminate the challenges being faced by small and medium tiger nut farmers during harvesting. Materials selection for constructing the harvester were based on their durability and availability, affordability and ease of replacement if damaged. They include mild steel (3 mm, 5 mm), 30 mm galvanized steel hollow pipe, 10 mm diameter steel rod, and 400 mm steel tyre. The developed harvester was evaluated at the experimental farm of the Institute for Agricultural Research (IAR). Results of the study show that the average field capacity ranges from 0.28 – 0.33 ha/h while the average field efficiency was between 77.78 – 80.49% depending on operating speed, moisture content and other properties of the soil. No field damage was recorded when the harvester was used as against an approximate 10.50% damage recorded in the manual harvesting method.

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.

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.

Lightning is a natural phenomenon that cannot be prevented, therefore the specific system need to be installed in the building to reduce or eliminate the impact of lightning flash and safely discharge to the ground. The country along the equator including Africa, South America and Southern Asia received the highest number of lightning. Malaysia experienced in average of 100 to 140 days of lightning and 600000 to 1300000 number of lightning flash per year. This research is conducted to identify the materials selection for the lightning protection system especially the down conductor cable. Several projects around Malaysia had been selected for this purpose. From the research, they are two types of lightning protection system commonly implemented in Malaysian buildings; the conventional method and structural bonding method. It was found that 23 % of the projects used structural bonding method, mostly from the government projects, and 77% of the projects used conventional method. For the down conductor cable selection, the conventional method used the copper and aluminium tape. And for the structural bonding method the galvanized steel iron was used as the down conductor cable.

A field experiment was conducted in two different locations at Agricultural Research Station of Garmat Ali in Basrah-Iraq. The aim of this investigation is to evaluate the effective field capacity, field efficiency, draft force, pulverization index (PI), soil bulk density and soil porosity for moldboard plow (primary tillage), mounted disk harrow and offset disk harrow (secondary tillage) under different operating speed (2.54 (S1), 3.84 (S2) and 5.77 (S3) km hr-1) in two different soil textures (silty loam soil and clay soil). The design of the experiment was complete randomized blocks design in factorial experiment. The results showed that the moldboard plow had high values of draft force, pulverization index (PI) and soil porosity and lower soil bulk density, effective field capacity and field efficiency than that of mounted disk harrow and offset disk harrow in both soils. The operating speed and the interaction between operating speed and implements tillage type had significantly affect (p < 0.05) on all the studied parameters. The silty loam soil achieved higher effective field capacity, field efficiency, soil porosity (low bulk density) and considerable pulverization of soil clods than that of clay soil. The results also showed that the optimal operation conditions of implements tillage were associated with high operating speed of 5.77 km hr-1 in silty loam soil especially with using the disks harrow.

<p>Statistics on the machinery performance are essential for farm managers to make better decisions.<strong> </strong>In this paper, the performance of all machineries in five sequential operations, namely bed forming, stone separation, planting, spraying and harvesting in the potato production system, were investigated during one growing season. In order to analyse and decompose the recorded GPS data into various time and distance elements for estimation of the machinery performance, an automatic GPS analysis tool was developed. The field efficiency and field capacity were estimated for each operation. Specifically, the measured average field efficiency was 71.3% for bed forming, 68.5% for stone separation, 40.3% for planting, 69.7% for spraying, and 67.4% for harvesting. The measured average field capacities were 1.46 ha/h, 0.53 ha/h, 0.47 ha/h, 10.21 ha/h, 0.51 ha/h, for the bed forming, stone separation, planting, spraying, and harvesting operations, respectively. These results deviate from the corresponding estimations calculated based on norm data from the American Society of Agricultural and Biological Engineers (ASABE). The deviations indicate that norms provided by ASABE cannot be used directly for the prediction of performance of the machinery used in this work. Moreover, the measured data of bed forming and stone separation could be used as supplementary data for the ASABE which does not provide performance norms for these two operations. The gained results can help farm managers to make better management and operational decisions that result in potential improvement in productivity and profitability as well as in potential environmental benefits.</p>
