  • Performance of trucks working in sugarcane transportation

this study was conducted at Kenana Sugar Estate with the objective of the evaluation of failures and downtime of trucks operating in sugarcane transportation. Results showed that there was no significant difference between seasons within the same type of trucks. there was significant difference between the different types of trucks in the frequencies of failures. the transmission system and clutch have the most failures in sugarcane transportation due to the harsh conditions of opeartion. Radiator failures also were affected by the condition of operation. Accidents contributed to about 60% of the total downtime

  • Evaluation of failures of tractors working in sugarcane transportation

This study was conducted in Elguneid Sugar Factory with the objective of the evaluation of the failures of tractors operating in sugarcane transportation. Results showed that there was no significant differences between seasons for the same type of tractors. there was significant differences between the different types of tractors in the frequencies of failures. the tires and gearbox were the major failures of tractors (A) while cranking and electrical failures were the major problems of tractors type  (B).

  • Effect of dry-off period and crushing and extracting delays on sugarcane quality and productivity

In sugar production, the costs of harvesting and transporting the crop account for a large proportion of cost. To ensure sustainability of the industry, it is of vital that performance in the harvesting and transporting process be optimized so as to reduce the cost to a minimum. These experiments were carried out at Sennar Sugar Factory to show the effect of dry-off period and time lag between cutting and crushing of cane on sugar quality. Five dry-off periods were selected namely, two-, three-, four-, five- and six weeks dry-off periods. The time lag was selected to be 24, 48 and 72 hours after cutting. The measured parameters were percentage of weight loss, pol, brix, purity, fiber content and sugar recovery. Analysis showed that there is a high significant effect of delay in cane crushing on these parameters. From the results it can be stated that it is necessary that cane cutting, transporting, and crushing periods should be kept to the minimum. Cane supply system should be highly effective to minimize losses.

  • Determination of optimum dry-off period for efficient machine performance in sugarcane harvesting and loading systems

 

This experiment was conducted at Sennar sugar factory to determine the effect of dry-off period for efficient machine performance. Two systems of harvesting were studied, namely, mechanical and manual harvesting. Five dry-off periods were tested, one-, two-, three-, four- and five weeks dry-off periods. Although there were no significant differences, it was found that the optimum dry-off period could be the four and five weeks because it gave the lowest fuel consumption, the lowest loading time and the best and second best machine output.

  • ENERGY CONSUMPTION AND ECONOMIC ANALYSIS OF RAINFED SORGHUM UNDER CONSERVATION PRACTICES AT DIFFERENT FERTILIZERS LEVELS

Field experiments were conducted at Indian Agricultural Research Institute, New Delhi during rainy seasons of 2011 and 2012 in split-plot design to study energy consumption and economics of sorghum production [Sorghum bicolor] under conservation practices and different fertilizers levels. Sorghum variety ‘CSH 14’ was planted using two tillage types (minimum and conventional) and two planting methods (ridges and furrows, and flat-bed). For each type of tillage and method of planting three levels of fertilizer were applied. The results revealed that fertilizers are the most energy-consuming, which were 50.1 and 48.2% of total energy inputs respectively for the both seasons, among those, nitrogen was the highest energy consuming. Total energy used for producing sorghum was found as 6.9×103 and 7.2×103 MJ/ha and the total output energy was 97.2×103 and 84.7×103 MJ/ha respectively for the both seasons. The values of energy use efficiency, energy productivity and net energy gained were greater in season 2011 (14, 0.22 kg/MJ and 90.3×103 MJ/ha) than in 2012 (11.7, 0.16 kg/MJ and 77.5×103 MJ/ha) respectively due to higher yield of grain and fodder and lower total input cost in season 2011. Value of specific energy was higher in season 2012 (6.2 MJ/kg). Ridges and furrows planting method in conventional tillage with 100% RDF (Recommended Dose of Fertilizer) have a significant impact on energy indices (i.e. gross energy output (Grain + Fodder), energy use efficiency, and net energy gained). Total expenditure for production was 139.1 and 146.7 $/ha, the gross production value was 324.3 and 268.3 $/ha, net return gained was 185.2 and 121.7 $/ha, and the benefit-cost ratio was 2.49 and 2.33 respectively for the both seasons. The treatments had significant effect on energy and economic indices, which justifies the adoption of ridges and furrows planting method in conventional tillage with 100% RDF for sorghum production, although it consumes more energy input (106.8%) and higher expenditure (32.7%), but it provides higher return of energy (155.3%) and money (139.1%) as compared to the flatbed planting in minimum tillage with 100% RDF.
