- W2898870513 abstract "Purpose. To provide the scientific basis for material costs, economic efficiency assess and bioenergy evaluation of “technological elements” of seed production of lettuce ( Lactuca sativa L.) varieties in the conditions of Ukrainian Polissia. Methods. During the years 2013–2015 at the “Maiak” Research Station of the Institute of Vegetable and Melon Growing of the National Academy of Agrarian Sciences of Ukraine, 12 salad varieties of different types were studied: leaf var. secalina (‘Snizhynka’, ‘Zorepad’, ‘Malakhit’, ‘Dublianskyi’), head var. capitata (‘Hodar’, ‘Smuhlianka’, ‘Dyvohrai’), romaine var. longifolia (‘Sovskyi’, ‘Scarb’) and stem var. angustana (‘Pohonych’, ‘Pastushok’, ‘Skrypal’). Results. The production of lettuce seeds is rather labour-intensive process. The largest share of expenditures in its overall structure (15–26%) takes crops care and harvesting, remunerations and costs for petrol and oil. The lettuce seed productivity (according to the varieties) was: 0,34–0,49 t/ha (leaf var.); 0.31–0.54 t/ha (head var.); 0.36–0.43 t/ha (romaine var.); 0,38–0,45 t/ha (stem var.). The highest value of the seed croppage provided the ‘Dyvohrai’ variety. The first cost for 1 kilogram of lettuce seed production varied from 36.67 to 63.87₴. The highest cost was for ‘Hodar’ variety (63.87 ₴/kg), ‘Snizhynka’ (58.24 ₴/kg) and ‘Sovskyi’ (55.0 ₴/kg), the lowest – for ‘Dyvohrai’ (36.67 ₴/kg) and ‘Dublianskyi’ (40.41 ₴/ha) varieties. The varieties, which formed a sufficiently high yield, ensured a high level of profitability: ‘Dublianskyi’ – 167%, ‘Dyvohrai’ – 142%, ‘Skarb’ – 108%, and ‘Skrypal’ – 123%. The coefficient of bioenergy efficiency of seed production of all lettuce varieties, for the non-seedling method of cultivation, was 1.2 on average, in particular for var. secalina – 1.1, var. capitata and var. longifolia – 1,2, var. angstana – 1.3. Conclusions . Calculated indicators of economic efficiency and bioenergy estimation of lettuce seed production confirm the expediency of all Lactuca sativa L. varieties cultivation for seed production purposes in the conditions of Ukrainian Polissia." @default.
