Yield and Yield Components
There are no significant differences in seed dry matter accumulation and yield components between PL and NL treatment (Fig. 8 and Table 3). Again, PL significantly increased seed dry matter accumulation starting from the first 25 days, and peaked at 30 days, then declined until day 40. NL also increased seed dry matter accumulation from day 5 to a peak at 25, then reduced until day 40 (Fig. 8). These results indicated that partial light (80% transmittance of normal light) can delay leaf senescence for almost 5 days but get the same yield of normal light, which means it’s possible to use a narrow-wide-row planting pattern to obtain the same yield with monoculture but save more land for other crops growth.
