Abstract
Effects of the different sowing date,nitrogen level,sowing rate on grain yield,yield components and phytic acid content were studied in the field experiment with early rice variety Jiayu253.The yield,yield component factors,and the content of phytic acid in paddy rice,brown rice,and milled rice were measured.The main results were shown as follows: in term of single factor,the yield of rice reached the highest when the sowing date was on April 15,and the yield treated with 13kg / 667m2 N or 6kg / 667m2 sowing rate was significantly higher than those of other treatments,respectively;considering all factors,the yield of rice reached the highest under the treatment of sowing date on April 8,application of 13kg / 667m2 N,and 6kg / 667m2 seeds;phytic acid contents in brown rice were quite different among different sowing dates or nitrogen levels,showing a downward tendency with delaying sowing date or increasing nitrogen.However,there was no significant difference among sowing rates;on the contrary,the phytic acid content in milled rice was obviously insensitive to the sowing date,the nitrogen level,and the sowing rate.Thus,the results indicated that agronomic measures had little effects on the phytic acid content in milled rice,and wouldn’t affect the mineral availability.
