t0“nitrate accumulation and yield of lettuce varieties”
e4“The content of nitrates in lettuce plants of different varieties varied more strongly when grown on the background of N 200 and ranged from 10.7 to 13.6 times (on average over 2 years – 11,2 times), on the control of N 0 – 33 times”

Other claims from this paper (12)
- Observation Yield differed 4.5 times between lettuce varieties under the N200 background.
- Observation Yield differed 5.7 times between lettuce varieties under the N0 background.
- Observation Varieties All the Year, Quedlinburger Dickkopf and Berlin Yellow gave the highest yield, 2.22-2.64 kg/m 2, under increased nitrogen nutrition.
- Observation Variety Great lakes gave the highest yield, 2.22-2.64 kg/m 2, under increased nitrogen nutrition.
- Observation Azart and Odessa Kucheryavets stood out in yield under the nitrogen-deficient background.
- Observation Azart and Odessa Kucheryavets absorbed soil nitrogen better than other varieties under the nitrogen-deficient background.
- Observation Nitrate content varied among lettuce varieties 10.7 to 13.6 times under the N 200 background.
- Observation Some lettuce varieties accumulated maximum NO3 under excess nitrogen nutrition.
- Observation Lettuce Romaine had a low nitrate content of 353 mg/kg.
- Observation Lettuce White paris cus had a low nitrate content of 198 mg/kg.
- Association The period of maximum biomass increase corresponded to a maximum decrease in NO 3 in lettuce plants.
- Recommendation There may be some scope for NO 3 reduction in lettuce through cultivar selection or breeding.
