[Synopsis] The pumpkin in a certain Masatoshi Hioki. Field (corn of front for food) from April 14, 2007 to August 7 of the same year installing the examination district of one district 24m^2(4.5m×5.3m) two repetitions. At Hokkaido Yubari-gun Kuriyama-cho Sakurayama the examination (Variety: Kurimaron from Ltd.Blantec) It was for. Three districts (the contrast district, the habitual practice district, and the examination district) were installed, the manure ratio of an organic transformation and Kuripit was changed, and it experimented on the examination district. It sowed on each examination district and April 14, and 10a (490cm×55cm) 371 stock/was transplanted on May 18. The black soil multi-put when transplanting, it grew by tailoring one the vine, and it harvested on August 7. 1.The difference was not seen in the examination district and the habitual practice district though thecontrast district of the length that 40 days after it transplanted hung was the longest. 2.The difference was hardly admitted in all the examination districts in the number of leaves, the contrast district was the longest in the length of the leaf, and the difference was admitted in the habitual practice district and the examination district. 3.There was not a difference in either of the width of the leaf or the length of the stalk the examination districts either. Therefore, it was clarified that using Kuripit according to Hence of an organic transformation kept the growth of the ground part equal. 4.The level of the examination district of the putting on number of period's title is equal to the habitual practice district. 5.There are a lot of contrast districts of putting on number of squash per stock, and 0.3-0.4 piece has decreased in the habitual practice district and the examination district. 6.Average squash weight of the examination district was a little inferior compared with the contrast district. 7.Amount of good squash for each 10a was about 10 percent extra of the habitual practice district. The section difference is admitted and characteristics of fruits in each examination district are guessed to be unquestionable for the use of Kuripit. The amount of total nitrogen seemed to be necessary about 15 kg though the examination of the amount of turning on of Kuripit was more necessary from the above-mentioned result in the future. Moreover, total sugar content and starch+ total sugar content was the highest in the district of result... contrast where the quality had been examined. On the other hand, either of the habitual practicedistrict or the examination district the analysis values were also inferior to the contrast district. This seems the one by the difference of the amount of using of Kuripit. Therefore, it seems that there is a necessity for examining the manure ratio of an organic transformation and Kuripit further.
