Comparison of Dry Matter Production and Photosynthetic Rate against Different Planting Dates between Late and Early Maturing Soybean cultivars in Paddy Field

Abstract

which was 244 and 213 g m –2 , respectively. Also, the number of pod, number of seed and seed per pod were higher in PSNK than in NCK. The leaf area and top dry matter were higher in PSNK than in NCK, especially, at 60 and 70 days after emergence, respectively. Photosynthetic rate (PN) at flowering stage (R1), there was no significant difference between cultivars in the uppermost leaf but there was a significant difference in PN of the 7 th leaf on seed development stage (R5).
