| The significance of the seed and root properties grows in organic and in ecological agriculture due to lower level of agrotechnical input. When compared with conventional agriculture, seed germination takes place in relatively "worse conditions" in the low input system and therefore seeds of cultivars of high quality, vitality, efficiency of water-use and with resistance to soil stresses during germination, must be used. A similar problem exists in organic agriculture when root growth and development takes place in relatively "worse conditions"and therefore the root system must have the optimum structure, depth of penetration, efficient nutrient uptake and their transport, increased resistance to soil stress, good growth energy and optimal ratio to... |

| • In 2000 an organic rotation research and demonstration experiment was set up at Teagasc (Irish Agriculture and Food Development Authority) Oak Park, Co. Carlow, with an overall aim ‘to improve the yield and quality of organic arable crops in Ireland’ • A field scale, long term, stockless seven year rotation experiment was established having three replicates. The single rotation consisted of two years grass / clover pasture followed by five years of cropping, three in cereals, one potato and one legume crop. • The area was previously in long term silage pasture, which provided a good base from which to convert to organic. • Within and across the plots a range of ‘component research’ was undertaken, mainly cultivar comparison and some sowing rate... |
