Summary. During the study elements of technology of cultivation of coriander in the open ground of the southern areas of the Amur region were explored. Field experiments included testing of 7 varieties of coriander. In this case, optimal planting dates and layout of culture, forms the surface of the soil and the dose of fertilizer were determined. Field experiments were conducted from 1991 to 2011 on meadow-chernozem soil, which had a slightly acid reaction of the soil medium pH aq. from 5.9 to 6.3 with a humus content in the soil from 4.18 to 4.41 %, total nitrogen from 0.20 to 0.22 %, and total phosphorus from 0.2 to 0.31%. Content in the soil exchangeable potassium was 12...25 mg/100 g, and available phosphorus 2.5...4.0 mg/100 g. It was found that the optimum period of sowing coriander is from April 25 to May 5. The most appropriate scheme sowing coriander is 20 +20 +20 +80 cm. Belt sowing (5 +27 +5 +27 +5 +71 cm) increases the yield of greenery on average 0.53 t / ha , but it leads to reduced seed production by 10 ... 15%. Ridges provide the most favorable conditions for commodity products and seeds. The optimal dose of nitrogen, phosphorus and potassium in the preparation of the green was 30 kg active substance/hectare of active substance, and in the preparation of seeds of 60 kg active substance/hectare. The proposed technology allows the green coriander yield to 11.5 t/ha, reduces production costs and energy costs of its production.
Keywords: coriander, energy-saving technology of cultivation, efficiency of plants.
