Other claims from this paper (14)
- Intervention effect NPK treatments significantly increased shoot diameter in both studied years.
- Intervention effect NPK treatments significantly increased shoot length in the first year only.
- Intervention effect Differences between NPK and control for shoot number and leaf area were not statistically significant.
- Intervention effect NPK treatments significantly enhanced leaf total chlorophyll (SPAD) in 2009.
- Intervention effect NPK treatments induced high leaf N% in both studied seasons.
- Intervention effect NPK treatments induced high leaf K% and P% in 2008 only.
- Intervention effect NRMM treatments significantly increased leaf Mn and Zn in both growing seasons.
- Intervention effect NPK treatments significantly enhanced leaf Fe in the two years.
- Intervention effect NPK treatments induced high fruit yield per tree in both seasons.
- Intervention effect Fruit quality did not differ significantly between NPK and NRMM treatments.
- Intervention effect Increasing the magnetite raw rate significantly increased vegetative growth, leaf total chlorophyll and leaf mineral composition.
- Intervention effect Increasing the magnetite raw rate significantly increased yield and fruit quality.
- Observation Heavy metals (cobalt, nickel and lead) in fruit were within permissible limits.
- Recommendation Using natural raw mineral mixture and magnetite as a substitute for chemical fertilizers in pear trees was reasonable, but more studies are needed.
