Other claims from this paper (11)
- Intervention effect Foliar Cu fertilizer application at the flag-leaf stage increased wheat grain yield with all four Cu fertilizers in 2000 and 2001, and with all but Cu sequestered II in 1999, relative to the zero-Cu check.
- Intervention effect Foliar Cu application at the four-leaf stage increased wheat grain yield only in 2001.
- Intervention effect Soil incorporation of all Cu fertilizers at 2 kg Cu ha -1 increased wheat grain yield only in 2001.
- Intervention effect Soil incorporation of two Cu fertilizers at 0.5 kg Cu ha -1 increased wheat grain yield only in 2001.
- Intervention effect Seedrow placement of two Cu fertilizers at 1 kg Cu ha -1 increased wheat grain yield only in 2001.
- Intervention effect Cu fertilization had no effect on protein concentration in wheat grain.
- Intervention effect Residual DTPA-extractable Cu in the soil increased under soil incorporation of Cu lignosulphonate, Cu sulphate and Cu oxysulphate II, particularly at 2 kg Cu ha -1.
- Recommendation Foliar application of Cu fertilizers at the flag-leaf growth stage can be used for immediate correction of Cu deficiency in wheat.
- Recommendation Foliar application may be the most practical and economical way to correct Cu deficiency in wheat during the growing season.
- Recommendation Lower Cu rates can correct Cu deficiency in wheat.
- Observation Wheat plants in the zero-Cu treatment exhibited Cu deficiency in all years.
