Other claims from this paper (18)
- Association Shoot dry matter yield in alkali soil was only 35% of that in normal soil.
- Intervention effect Combined 5 ppm Zn, 250 ppm K and gypsum application to alkali soil recovered yield to 91% of normal soil.
- Intervention effect Combined 5 ppm Zn, 250 ppm K and gypsum application to alkali soil recovered yield to 75% of normal soil.
- Intervention effect Combined 5 ppm Zn, 250 ppm K and gypsum application to alkali soil recovered yield to 70% of normal soil.
- Intervention effect The highest yield was recorded with 10 ppm Zn, 250 ppm K and gypsum applied to alkali soil.
- Intervention effect The highest-yield treatment (10 ppm Zn, 250 ppm K, gypsum) gave 14% more yield than normal soil.
- Intervention effect The highest-yield treatment (10 ppm Zn, 250 ppm K, gypsum) gave 59% more yield than Zn-treated alkali soils.
- Association The magnitude of Zn and K response in alkali soil was smaller after gypsum treatment.
- Association Responses to Zn, K and gypsum were negligible in normal soil.
- Association Zinc concentration decreased under alkali soil conditions.
- Association Gypsum and K enhanced Zn utilization by maize.
- Association Shoot Na was highest in alkali soil and lowest in normal soil.
- Association Zinc decreased shoot Na and 250 ppm K also decreased Na; the Zn, K and gypsum effect on Na was diminished when treatments were combined.
- Association Shoot K was highest in normal soil and similar in alkali and gypsum-treated soils.
- Association Shoot K increased most with K in alkali and gypsum-treated alkali soils; Zinc decreased shoot K in alkali soil.
- Association Interrelationships between Na, Zn/K and Ca showed decreased effectiveness on Ca concentration when applied together.
- Association Shoot Mg accumulated more in alkali soil than in other soils without K or Zn; antagonism between K and Mg and between K and Ca was evident.
- Association The yield increase in alkali soil with Zn was associated with enhanced Zn and Ca uptake, decreased Na concentration and widened Ca/Na and K/Na ratios.
