Evaluation of different methods of lentil harvesting
1982
Papazian, J.
The main objective of the trials was to evaluate six different methods of lentil harvesting under six different types of planting combined of two genotypes of lentils (small and large seeded), and three methods of planting (conventional, drilling and drilling followed by rolling). The six methods of harvesting used were hand pulling, scythe cutting, use of bean cutter, side mower, forage harvester and combine harvester. The interaction of these variables with the following characteristics was studied: lentil grain and straw yields, lentil grain and straw losses, lentil grain breakage, germinability and physical purity, straw quality, protein and fibre content, timeliness, man-power and energy requirements and total harvest cost. The results showed that hand pulling gives the best yields, but number of labourers needed and the cost of harvest were the highest with this method. The bean cutter was the most promising method for harvesting lentils mechanically. Use of scythe resulted in large losses of grain and straw and required skilled labourers. The combine was the cheapest method tested but losses were the highest. The methods using the cutterbar gave 40 to 50% straw loss and large loss of grain, and were more effective on rolled land. However, rolling reduced yields, and planting by drill gave higher yields than conventional planting, and the large seeded lentil yields were higher than those of the small seeded genotype.
