single seed

LEMKEN, a specialist for professional arable farming with annual sales of EUR 344 million, and a global company employing more than 1,200 staff, is one of Europe’s leading suppliers. Founded as a blacksmith’s shop in 1780, this family-operated company produces high-quality, high-performance agricultural implements for soil cultivation, seeding and plant protection at its German headquarters in Alpen and its two production plants in Föhren and Haren. Innovation in the best interest of our customers guides our thoughts and actions. For additional information on LEMKEN please visit our homepage at ´

In its Azurit single-seed drill, LEMKEN has opted for the novel DeltaRow technology, which provides each and every plant with 70% more surface area for growth than conventional placement in single rows. This in turn ensures plants have better access to light and are better supplied with water and nutrients.

DeltaRow crops can be easily harvested with current silage and grain maize harvesters. Trials conducted over several years have confirmed that this technology allows higher yields to be achieved. LEMKEN will launch its DeltaRow seeding technology on the market with its new Azurit single-seed drill.

DeltaRow technology involves a singling unit depositing seeds in an extended furrow comprising twin rows spaced 12.5 cm apart. Seed singling is performed by two synchronised perforated discs offset against each other by half a grain spacing. As each of the perforated discs only singles every other seed, their diameter can be kept narrow and their circumferential speed be minimised. The greater time interval available for singling results in outstanding quality of placement at high speeds of travel. A fertiliser band is placed centrally underneath the DeltaRow. Placement in a triangular seeding pattern ensures that seeds are positioned optimally in relation to fertiliser and obtain maximum benefit from it.

This work has been outstanding and one of GRDC’s investment success stories with practical impact on the ground.

The platform achieves five to eight generations per year in the major crop legumes. The benefit for plant breeders is a ready supply of new varieties to the farm gate much faster than previously.

An industry measure

The plants begin to flower within 20-30 days, under controlled lighting, airflow, water and temperature conditions.

Working in close collaboration with breeders means that there is a faster release of novel varieties to the farmers.

Their goals were to develop a system that:

Three selection methods (single seed descent (SSD), mass selection and selective intermating) were applied simultaneously to a highly heterogeneous and broadly based population of greengram. Progeny developing after two cycles of selection were evaluated for yield and seven other economic characters. The relative efficacy of each selection method was judged on the basis of the number of high yielding progeny, mean yield of top 10% progeny, and mean of the highest yielding progeny. Selection after two cycles of selective intermating was found to be the best method for generating productive progeny although mass selection favouring smaller seeds was an equally efficient method. Both of these were found superior to SSD selection.
