Q.2. Study the following table of Soybean different maturity groups and their yield in the U.S.A Maturity group Yield (bu./Acre) Length of the vegetative Length of the Reproductive period (seed filling period) in days 35 35 period in days 45 46 35 49 Maturity group 5 have longer vegetative growth period (45 days), however; botth maturity groups have the same seed yield! 1. Explain why both soybean maturity groups have similar yield? 10 Points 2. Does the length of the vegetative growth period affected plant yield formation? Yes, or No, Explain your answer. 10 Points 3. In the graph provided below draw the LAl curve for the Maturity group 00 and Maturity group 5. 5 Points

Explanation / Answer

2) The growth period is an important factor in determining the size of the yield. The size of the plant increases with the length of the vegetative period and hence increases the yield, as bigger plants produce more buds than smaller plants. More the density and number of buds, more will be the yield.
