Effect of Application of Pig Manure Slurry to Rye on Rice Productivity in Paddy-land
2005
This study was conducted to examine the effect of application of pig manure slurry(PMS) for rye cultivation in Paddy-land on rice productivity The field experiments were carried out from 1999 to 2002 on well-grown rice in Paddy-land at Kimje, Chunbuk province in Korea. PMS was manufactured by the fermentation for 6 months in natural condition. Amount of PMS was adjusted equal to total nitrogen value relative to its value of commercial chemical fertilizers. The amount of PMS were spread evenly over the soil surface two times; first in the autumn (before sowing, end of November) and second in the spring(regrowth of rye, middle of March). The field plots were consisted of four kinds (PMS treatment, PMS treatment PMS treatment with half of CF (CF ), Full of CF treatment (CF ). The experiment was designed as a randomized complete block. Each treatment was replicated three times. Rices are customarily gown under tropical korean condition as annuals. The results obtained from this study were summarized as fellows. Panicle length of rice was shorter in PMS than other treatments. Ripening grain ratio was the lower in CF treatment. In treatment of PMS and PMS , 1000 grain weight was a downward trend as compared to that of full of CF treatments, whereas number of grains per was increased as compared to other treatments. Number of panicles reveals that there is an increase in order; CF $50\% + PMS\;100\%>\;PMS\;100\%\;>\;CF\;100\%\;>\;PMS\;200\%$. Yield of milled rice showed hi인 in CF and , but were was no significant difference among treatments. There were did not a regular tendency in the ratio of leaf sheath bright, however the ratio of lodging area was higher in treatment than other treatments. Based on the results of this experiment, may be the most effective in rice productivity under application of PMS for rye cultivation in Paddy-land.
