✓ located verbatim in the source · abstract, characters 175–185 Other claims from this paper (11) Intervention effect Fertilizer increased corn yield at all locations. Observation Fertilizer yield gains ranged from 7.5 to 101.9 bushels per acre. Association Fertilizer response varied with population, initial soil fertility, and to a lesser extent hybrid. Intervention effect At high fertility, populations above 8,000 plants per acre increased grain yields in all hybrids. Observation At high fertility, lowest density gave lowest yield and approximately 24,000 plants per acre gave best yield. Observation At low fertility, density response varied from slight increases to slight consistent decreases. Intervention effect At high fertility, raising population from 8,000 to 24,000 increased yield by 64.8 bushels. Observation Intermediate populations produced intermediate yield differences at both fertility levels. Observation At high fertility up to 16,000 plants per acre, the late hybrid generally yielded more than adapted and early hybrids. Observation Above 16,000 plants per acre, the adapted hybrid generally equaled or exceeded the late hybrid. Observation At low fertility, hybrid yield differences were small and inconsistent, with general advantages for adapted and early types.

Yellowing nearly explained the decrease in net assimilation if yellowed leaf parts do not photosynthesize, although similar carbohydrate fluctuations suggest photosynthesis may be little slowed and respiration may instead increase.

e0 “The yellowing almost sufficed to account for the decrease in N.A.R., if yellowed parts of leaves do not photosynthesize. ”
✓ located verbatim in the source · abstract, characters 461–581 e1 “However, the similar diurnal fluctuations of carbohydrate in the laminae of healthy and infected leaves suggests that photosynthesis may not be much slowed by infection; if so, the decrease in N.A.R. indicates a large increase in respiration rate, especially of the root. ”

✓ located verbatim in the source · abstract, characters 0–85 Other claims from this paper (18) Intervention effect Beet yellows infection depressed sugar-beet dry-matter yield by decreasing leaf area and net assimilation rate, without reducing leaf number. Intervention effect End-of-June yellows infection yellowed 30‐50% of leaf area from mid-August; later infection caused less yellowing. Intervention effect Late-sown infected plants had a greater leaf-area reduction but a smaller net-assimilation reduction than early-sown plants. Observation Similarly treated plants had the same leaf-area reduction across two years but a much greater net-assimilation decrease in the second year. Intervention effect Yellows dry-matter losses were mostly in roots, petiole dry weight also decreased, and leaf-lamina dry weight was little affected. Intervention effect Yellows greatly increased reducing sugars and caused smaller sucrose and starch increases in leaf laminae, beginning with etch symptoms; starch effects peaked then while sugar effects increased with yellowing. Intervention effect Yellows reduced leaf-lamina water content, nitrogen content and arealweight ratio. Mechanism The carbohydrate rise could explain the nitrogen-content change but not the other leaf-lamina changes. Intervention effect Yellows did not affect petiole and root water content but increased their nitrogen content. Mechanism Yellows reduced root sucrose content, while decreased root weight accounted for most sugar-yield loss. Intervention effect Beet mosaic infection decreased sugar-beet dry weight only with nitrogenous fertilizer, through reduced leaf area and net assimilation. Intervention effect Mosaic depressed dry weights of leaf lamina, petiole and root. Intervention effect Mosaic did not affect leaf-lamina carbohydrate content, water content or arealweight ratio. Intervention effect Mosaic did not affect petiole and root water content. Intervention effect Mosaic increased nitrogen content throughout plants receiving no nitrogenous fertilizer, but not in nitrogen-treated plants. Intervention effect Mosaic slightly increased root sucrose content. Intervention effect End-of-June mosaic infection caused a 20 yo sugar-yield loss in nitrogen-fertilized plants. Intervention effect Yellows infection of similar plants at the same date reduced sugar yield by 50%. Intervention effect observed original result measured Claim · model-written summary
