Agronomy of lentil harvest mechanization
1990
Erskine, W. (ICARDA, Aleppo (Syria))
Present status of land preparation and methods of sowing for mechanical harvesting of lentils, compared with the traditional farming practices, were discussed and problems and advantages considered were concerning seeds; seeding rates; harvesting equipment and its use; increase in uniformity of germination; weeds and weed control (hand weeding, inter-row cultivation, herbicides). Furthermore, management practices in controlling weeds in lentils while, at the same time, increasing yield were recommended by planting at narrow row spacing with high planting density. Breeding for mechanical harvesting and the importance of a tall, erect, non-lodging plants with the lowest pod high at least 10 cm above ground, characterized the advantages of such type of crop which also includes better recovery of straw and seed. Breeding for non-dehiscence and non-shedding pod characteristics also lead to improved seed yield. The paramount importance of stage of maturity for mechanized harvesting and the "different best time" for each machine were pointed-out. Significance of the effect of harvest methods on yield and straw quality of lentil and crop residues with nitrogen fertilization rates on succeeding cereal crop were briefly discussed, based on investigations during 1984/85, 1985/86 and 1987/88 seasons
