Planting of turmeric has been a challenge to the farmers in Nigeria due to the absence of planting machine. The farmers are left to the traditional method of planting with hoes and cutlasses. This method is time consuming, labour intensive, associated with human drudgery and a high demand for human energy. As a result, a mechanical planter was designed and fabricated. The main objective of the study is to develop and evaluate the performance of a tractor- drawn turmeric planter. The planter was designed, fabricated and tested in the Agricultural and Bioresources Department of The Federal University of Technology, Minna. It consists of a ground drive wheel, hopper, metering system furrow opener, residue cutting edge, furrow closing device press wheel and power transmission mechanism. The performance tests of the fabricated machine were carried out using three levels of turmeric rhizome lengths (30 mm, 45 mm and 60 mm) at three levels of operational speeds (8km/h 10km/h and 12km/h). The results revealed that there was no steady pattern in the increase or decrease of miss index with increase in turmeric rhizome length and machine operational speed. The highest percentage turmeric rhizome miss index of 35% was recorded for turmeric rhizome length of 30cm at machine operational speed of 10km/h whereas the lowest percentage turmeric rhizome miss index of 15% was obtained for turmeric rhizome length of 60cm at the machine operational speed of 12km/h. The machine operational speed and size of the turmeric rhizomes affect the field capacity of the machine. The highest capacity of 0.96ha/h was recorded at the highest operational speed of 12km/h. The lowest field capacity of 0.63ha/h was recorded at the lowest machine speed of 8km/h. The developed machine could reduce drudgery involved in manual turmeric planting and save about substantial amount of labour and operating time.

The groundnut seed composed of approximately equal weight of fatty and non-fatty oil. The groundnut cake (kulikuli- Hausa name in Nigeria) contains concentrated protein, minerals, and vitamins in addition research finding revealed that no part of the nut is a waste. The kernel without the nuts can be used as hay to feed animals like, horse or ash manure. Planting machine or planter that is normally required to produce more food is beyond the buying capacity of smallholder’s farmers, which result in low productivity especially in the production of grains. An improved manual two-row groundnut planter was developed and evaluated for its performance using locally sourced materials which can be adapted for gardens and smallholder farmers. The machine has the following parts which are furrow opener, handle, frame, hopper, discharge tube, metering unit, and roller housing. The machine was evaluated for field capacity and metering efficiency (3 hole metering devices) at different forward speeds. It was observed that the machine field capacity efficiency of was 82%. Using standard error bars the highest metering efficiency of 92% was observed at 0.7 m s -1 machine speed. The ANOVA (analysis of variance) shows that speed as significant effect on metering efficiency with a p-value of 5.44E-18. The planter could plant an average of five seeds per point. It is simple, cheap and the ergonomics of the machine was considered which makes it easy to operate.

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 most critical operation in carrot cultivation because it is labour intensive (350 – 450 man-h/ha) and time consuming for the farmers. The present study was undertaken to evaluate the performance of single row tractor operated carrot digger designed by department of Farm Machinery and Power Engineering, COAE&T, CCS Haryana Agricultural University, Hisar, Haryana, India. The developed digger consisted of a digging, conveying, de-topping, collector and power transmission units. The carrot digger can be operated with 35 horse power tractor. It was evaluated under three variables viz., three digging blade angles (15°, 18°, 21°), three conveyor angles (25°, 35°, 45°) and three shoot catch heights (2, 4, 6 cm). The optimum value of variables obtained for operation of carrot digger were blade angle of 21°, conveyor angle of 250 and shoot catch height of 2 cm. Effective field capacity of the digger was 0.11 ha h-1 with field efficiency of 61.70 %. The digging efficiency, cut carrots, bruised carrots, picking efficiency and cutting efficiency of de-topping unit were 100, 0.62, 0.90, 62.29 and 100%, respectively at optimized value of operational variables. The labour requirement with developed carrot digger and manual method of harvesting was found 27 and 450 man-h ha-1, respectively. The operational cost of carrot digger was found Rs. 8242 ha-1 and it saves time and cost of operation in comparison to manual method of carrot harvesting. The break-even point, payback period and benefit cost ratio were 234 hours, 2.21 years and 1.56, respectively when operated for 400 hours annually. The carrot digger works better if carrots are sown in single row on the ridges rather than the broadcasting method.

Abstract The number of transients in hydro-mechanical power transmissions accounts for a significant portion of the total operating time and has a significant impact on drive economy. The quality of the transients largely depends on their duration and the type of working fluid used. The purpose of the work is to analyze the transients in the hydro-mechanical system, taking into account the effect of the duration of switching processes and the type of working fluid used. Determination of transient parameters in the hydro-mechanical power transmission was performed on the basis of mathematical dependences describing the switching process of two torque converters depending on the duration of the filling and emptying process and the influence of the type of working fluid used. Analysis of the calculated characteristics of transients in hydromechanical power transmissions showed that the main factor in the switching of torque converters, is the combination of filling and emptying processes, depending on the type of working fluid used. The obtained results give grounds to propose recommendations on coordination of filling and emptying processes in order to increase the efficiency of the hydromechanical drive.

The paper ‘GEARLESS DRIVE’ being compact and portable equipment which transmits power at right angle without any gears. Here, the L - shaped joint transmits the input power in such a way that the angular forces are produced and transmitted by the joints. The amount of friction generated is minimal compared to the power being transmitted. The material used for El-bow is made up mild steel material. The mechanism is screwed to the spindle which is driven by the gearless drive transmission connected to the drive system. The entire setup is constructed and placed on the base plate. There is no back lash during the power transmission. Therefore, the efficiency of 90% - 93% can be obtained in a gearless transmission mechanism. The Mechanical drives systems are economic when compared to electrical drives and their control and components are much simpler. These are widely used in industries ranging from aviation to heavy industry. In recent trends and advancements these types of drive has become more efficient
