Coming with the well-being era, consumer’s demand for safe agricultural products is increasing. It is urgent to develop an environment-friendly pear production system. Accordingly, this study was conducted to develop an environment-friendly pear production system by using several environment-friendly agricultural materials which is known to be effective in agricultural production. In the effects of environment-friendly agricultural materials on the soil chemical characteristics in pear orchard, the content of total carbon, organic matter, Ca and Mg increased a little respectively compared with those of 2008, and 2nd treatment showed the highest EC and Mg content in the soil among treatments. The content of leaf N, P and Ca in 2009 decreased compared with those of 2008, while Mg content showed no difference between 2008 and 2009 years. Average pear weight in 2009 was 31g higher than that of 2008 (682g) and 2nd treatment showed the highest pear weight (738g) among treatments. The average sugar content was higher in 2009 (12.6°Bx) compared with that of 2008 (12.2°Bx) and the plot of 2nd treatment highest sugar content (12.6°Bx) among treatments. There were no difference in hunter value of L among treatments, but hunter value of a showed higher 1.62 in 2009 than that of 2008 (3.73). The highest of gumminess and cohesiveness of fruits were obtained from 1st treatment and adhesiveness and chewiness of fruits were obtained from 3rd and 1st treatment respectively. Firmness of fruit increased a little in 2009 compared with that of 2008, while the highest firmness was obtained from 3rd treatment with 1.63㎏/5㎜∮ among treatments. Phosphate content in the peel of ‘Niitaka’ pear of fruit skin in 2009 (0.97g/㎏) showed 0.06g/㎏ more content than that of 2008 (0.91g/㎏), while the highest content was obtained from 3rd treatment (1.15g/㎏). Potassium content in the peel of ‘Niitaka’ pear in 2009 was 8.20g/㎏, which is 0.06g/㎏ more content than that of 2008 (7.82g/㎏) and the highest content was obtained from 1st treatment (8.34g/㎏) among treatments. The highest nitrogen content in the flesh of ‘Niitaka’ pear was obtained from 3rd treatment (4.32㎎/g), while it was the lowest in control plot (3.10㎎/g). Phosphate content in the flesh of ‘Niitaka’ pear in 2009 (8.20g/㎏) showed 0.06g/㎏ more content than that of 2008 (7.82g/㎏), while the highest content was obtained from 1st treatment (8.34g/㎏). There were no difference of the potassium content in the fruit peel of ‘Niitaka’ pear between years, but 1st treatment showed the highest content (11.81g/㎏) among treatments, while the lowest was obtained from the control plot (10.83g/㎏).
