Abstract
This study was conducted to evaluate the effects of ground cover treatments on the
nutrient contribution in a ‘Niitaka’ pear (Pyrus pyriforia) orchard. Treatments
included; 1) sod culture, 2) winter cover crop [ryegrass+hairy vetch], and 3) winter
[ryegrass+hairy vetch]+summer [greensolgo (sudan grass (Sorghum bicolor L.))+
nemajanghwang (crotalaria (Crotalaria juncea L.)] cover crops. Ryegrass and
hairyvetch were seeded with 6.4 kg/10a and 3.0 kg/10a, respectively, on October
17 of 2008, and greensolgo and nemajanghwang were seeded with 2.0 kg/10a and
3.0 kg/10a, respectively, on June 4 of 2009 at a diligent farmer in Boseong in
Chonnam. Winter+summer cover crops provided greater amounts of dry weight,
followed by winter cover crop and sod culture. The difference of amounts of dry
weight from the ground covers affected to the levels of total N, P, and K contents,
which were greater nutrient levels than those of recommended nutrient requirement
for satisfying 10- to 12-year-old pear tree growth. Greater amounts of dry weight
from the ground covers increased organic matter and concentrations of K and Mg
in soil. Foliar nutrient concentrations, as an indicator of nutrient status of a tree,
were not affected by application of ground cover treatments.
