Performance Evaluation on the Utilization of an Established Variable Amplitude and Frequency of Vibrating Container for Potential Application in Slowing Down Sprouting in Yam

A variable amplitude and frequency of mechanical vibrating container working on cam and follower mechanism have been established. This study carried out a performance evaluation on the utilization of the established vibrating container for potential application in slowing down sprouting in yam. The vibrating container is electrically operated and a variable speed electric motor of 15, 000 rpm was selected for the machine. The performance parameters of the established mechanical vibrating cont...

A Computer Model for Irrigation Water Indenting and Optimization of Minor Canal Operation

ABSTRACT This study was carried out with objectives of developing a proper decision aid for irrigation indenting of multiple crop rotation based on Penman- Montieth equation( 1994) and amenable for the format of meteorological data of the Sudan. Consequently the study developed a mathematical simulation of canal operation for the purpose of optimization of water allocation within such a canal. Linear programming algorithm was made to optimize irrigation water allocation between different outl...

Development of the Shape of the Cam Profile of Mechanical Yam Vibrator Using Cycloid Motion

At a high frequency of vibration; the cam of a vibrator always encounters the issue of jamming or the follower rolling off or losing contact with the cam when the appropriate design is not carried out. This study, therefore, developed the shape of the cam profile of mechanical yam vibrator using cycloid motion. Displacement equations from the base circle to the cam profile were developed to obtain the shape of the cam using cycloid motion. A vibrometer was used to evaluate the developed...

DETERMINATION OF ENGINEERING PROPERTIES OF TWO SOILS AT FOHREC (KADE) AND SIREC (KPONG)

Agriculture, its operations, and soils properties are inter-related. Cultivation of crops; tillage, irrigation and farm operations, commuting to and from farm plot and building of structures are greatly influenced by the soil specifically its properties. Shear stress, cohesion and angle of friction are parameters that play major roles in influencing how soils are used or worked on. It is, therefore, important to determine the shear stress, cohesion and angle of friction of the soils in Kade a...

THE EFFECT OF TIRE PRESSURE ON FUEL CONSUMPTION DURING TRACTOR-PLOUGH OPERATION.

In the world today, due to the high cost of running a tractor on a farm, there has been many research to see ways of minimizing this cost. Some of these cost come from the tire of the tractor, amount of fuel needed to run the vehicle smoothly, buying spare parts of the tractor and ensuring safety of the tractor. This thesis seeks to find the effect that tire pressures of vehicles have on the fuel consumption and the various ways of reducing this effect if there are any. An experiment was cond...

Agricultural Automation with Smart Irrigation System

As we know, nowadays issues in the agriculture field are a major concern. According to the Union Minister of Agriculture and Farmers Welfare Narendra Singh Tomar, 5,579 Indian farmers died by suicide in 2020. There are many conflicting reasons for farmer suicides which are mentioned by Activists and scholars but high debt burdens, crop failure, mental health, and personal issues have been some of the most common causes amongst them. So, what is the solution that would work in farmers’ favor...

Design, Fabrication and Performance Evaluation of Pedal Operated Groundnut Decorticator

ABSTRACT Shelling of groundnut pods (Arachis hypegea) by hand is tedious, laborious and unhygienic with low efficiencies. As a result farmer get low income due to amount of broken kernels and a lot of time is lost in the tedious shelling operation. To overcome this problem, pertinent parameters that influence shelling efficiency of pedal operated groundnut decorticator were identified. Pedal operated decorticator were designed and fabricated with chain and sprocket of bicycle and aluminum spi...

Development, Fabrication and Performance Evaluation of a Single Wheel Driven Boom Sprayer

ABSTRACT The single wheel driven boom sprayer was developed, fabricated and evaluated for its performance at the department of Agricultural and Bio-environmental engineering workshop, Kwara state polytechnic, Ilorin. The spraying performance was carried out at spraying height of 0.5m, 0.6m and 0.7m respectively. The theoretical  field capacity CT, the effective field capacity CE and  Field efficiency (ŋ) at spraying height of 0.5m  are 0.285ha/hr , 0.165ha/hr and 58%, while at spraying h...

Fabrication and Performance Evaluation of Cold Storage System

 ABSTRACTA portable cold room storage was developed. The system was tested with different types of perishable crops under different temperatures. The system is made up of two units, one, the evaporating unit that is where the produce was stored; it is made up of steel material with 79mm by 45mm in length and breadth. While the second unit is the trolleys, the system consists of a control switch that is calibrated to suit any type of produce stored in the system. It contain a separate basemen...

Impact Damage to Selected Agricultural Produce from South Eastern Nigeria.

ABSTRACT An Impact Test Apparatus was developed to determine the impact damage and bruise parameters of five fresh agricultural produce, namely: banana (Musa spp), tomato (Lycopersicon esculentum), sweet potato (Ipomea batatas), cassava tuber (Manihot esculenta) and lemon (Citrus limon) using Impact – Drop Height method. A constant impact energy of 0.9J – 4.5J was maintained as drop heights ranged from 0.20m – 1.00m. The bruise diameter, bruise depth, bruise width, bruise volume, bruise...

Selected Physical And Aerodynamic Properties Of African Breadfruit (Treculia africana) Seeds From South Eastern Nigeria

Physical and aerodynamic properties of African breadfruit (Treculia africana) seeds were studied at four moisture levels: 12.50, 15.00, 17.50 and 20.10% dry base (w.b). As moisture content increased from 10.50 to 20.10% (w.b), the average weight, major diameter, minor diameter, intermediate diameter, geometric mean diameter, arithmetic mean diameter of the seeds ranged from 0.35±0.08 to 0.60g±0.04g, 8.08±0.90 to 10.05±0.60mm, 4.04±0.53 to 5.00±0.10mm, 2.96±0.43 to 4.60±0.40mm, 4.52±0...
