Cassava is a major source of food and raw material for domestic and industrial uses in Nigeria. Consequently, the technologies involved in its cultivation from planting to harvesting require proper development. This paper reports the development of a labour-saving technology for harvesting cassava using standard procedures for designing soil engaging implements. Locally available materials were also used in the fabrication of the harvester. Results of trial tests indicate a digging efficiency of 58.9%, fuel consumption of 16 l/ha, field capacity of 0.11 ha/hr, field efficiency of 67.9% and root damage of 43.03%. The total cost of fabricating the machine was 184,000 naira only. Further tests under various soil and operational conditions for improvement and optimization were recommended for the purpose of patenting for commercialization.

For agricultural machinery management the actually reached machines capacity has a considerable importance. The data recorded by GPS monitoring enable to correct machines work productivity under concrete operational conditions. Assessment of machine aggregates operation records has proved effect of the operational factors onto operational efficiency reached on particular plots. The theoretical efficiency given by exploitation characteristics of machines has decreased effect of higher share of non-productive travels within small and irregular plots almost by 25%. In this paper we are dealing with searching for correlation between field speed and travelled unit path and defined classes of size, length and plot shape. The resulting knowledge of field efficiency on plots properties will enable to make more accurate the machines planned operation.

The ginger (Zingiber officinale) rhizome is harvested manually by different types of spade, fork or bullock drawn plow. These methods consume more time, cause drudgery, losses and low field capacity. Therefore a tractor drawn digger was evaluated for ginger crop. The performance parameters (exposed, cut, bruised and digging efficiency) of the digger were studied at 3 forward speeds and 3 blade angles. The performance of the digger was found satisfactory in respect of digging efficiency of 98.01%, and undug crop of 2.38 % at an average depth of operation of 15.75 cm. The damage was 1.98 per cent which was much low as compared to manual digging of ginger crop (9.73%). The machine takes 7.4 hours to dig one-hectare area of ginger crop with field efficiency of 87.82%.

Mechanical rice transplanting is gaining attention to the Bangladeshi farmers. However, service business on mechanical rice seedlings transplanting has not yet been developed due to various reasons. The 4-row walking type transplanter (model DP488) was operated in 54 farmer’s field at Ghaghatpara, Rangpur  Sadar and Kaliganjpara, Pairaband, Rangpur in late boro 2016 season to explore the entrepreneurial opportunity of commercial mechanical rice transplanting service for small holder farmer in Bangladesh. The field capacity and field efficiency of rice transplanter was obtained 0.15 ha hr-1 and 75%, respectively. Field capacity depended on the size and shape of the plots. Small plots having less than 250 m2 should be avoided for 4-row walking type rice transplanter to get the good machine performance. Fuel consumption was obtained 4 L ha-1 and varied over plot size, soil settlement time, presence of obstacle, plot to plot travelling distance and operator’s skill. Scattered plots increased travelling distance hence fuel consumption raised and reduced daily area coverage. Soil setting time should be allowed for 12-24 hrs for satisfactory machine performance. Mechanical transplanting took 18 man-hr ha-1 whereas mat loading, machine transport and cleaning took 1.6 man-hr ha-1 labors. Depending on the combination of seedling density in tray and density settings in machine the tray requirement varies from 153 ha-1to 222 ha-1. Tray distribution was observed as 90% in transplanting, 6% in gap filling and 4% pocket area. Gap filling by manual labor required 18-20 man-hr ha-1. Time distribution depended on managerial combination and relation between transplanting team and farmers. Seed rate showed negative correlation with seedlings population in tray and positive correlation with seedlings mortality. Number of turning events in plots can be minimized by selecting larger plot and operating transplanter in length-wise. Increasing daily coverage, minimizing fuel consumption and selection of sensible consumer group can draw good return from marginal input and establish business in secure environment.Progressive Agriculture 28 (3): 230-239, 2017

The possible volume reduction and stabilization of the sewage sludge associated with the melting process are expected to be greater than with the incineration process. In addition, melted slag can be utilized. However, since the melting process requires a very high temperature to melt inorganics (ash) in the sludge, the technologies to minimize energy consumption, to establish system operation and to prolong durability of facilities should be developed. This paper discusses the auxiliary fuel consumption as follows.(1)Preparation of a model that provides the auxiliary fuel consumption of the melting system on the basis of the mass and heat balances.(2)Evaluation of the auxiliary fuel consumption in the above model using the cake moisture content, the volatile solids of the cake, the dried cake moisture content and the melting temperature as parameters.(3)Examination of the operational conditions for an energy saving melting system based on the results of (1) and (2) above.

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 major labor intensive works in rice cultivation. Appropriate harvesting machinery is urgently needed to reduce labor and production costs. Production cost of rice becomes high due to labor shortage and high wage rate during harvesting time. Techno-economic performance of Korean self-propelled reaper (KR), China self-propelled reaper (CR) and BRRI reaper (BR) were evaluated in order to identify the field constrains and problems of the reapers at Mithapukur of Rangpur, Bangladesh during Aman season of 2013. The actual field capacities of the KR, CR and BR were found 0.18, 0.17 and 0.15 ha h–1with the corresponding field efficiency of 55, 68 and 56%, respectively. The variation of field capacity among the models was due to turning time losses, weight of the reaper and operator’s skill. The fuel consumption of the reapers was 4.11, 2.61 and 8.39 l ha–1 for KR, CR and BR, respectively. The shattering loss of paddy harvesting was 1.66, 1.50 and 1.45% for KR, CR and BR, respectively. The break-even area of the reapers was 9.15, 7.82 and 8.43 ha yr-1 for KR, CR and BR, respectively. It is evident that the reaper could be used successfully as labor saving and user friendly technology to eliminate post-harvest problems in Bangladesh.J. Bangladesh Agril.
