Source-sink relationship of soybean accessed by increasing in solar radiation through the plant canopy
نویسندگان
چکیده
The photosynthetic metabolism is a key point to improve soybean yield. In this work, we demonstrated that radiation use by plants can be improved, aiming the grain yield in lower canopy. objective of study was observe whether increase solar input canopy improves their performance. Three experiments were carried out during 2017/2018 season. For each experiment, treatments consisted opening one or two side rows cultivation at R2 and R5 stage (NA5909RR) until maturity, plus control. Increase on provided oppening enhanced potential nodes canopy, mainly when opened. main benefits increasing available throughout are observed number pods thousand-grain weight, demonstrating importance availability assimilates leaves. Interestingly, interceptation regardless area, which varied between 4.9 6.7 ton ha-1.
