Which of the following is not a smoother crop?(a) Soybean(b) Alfalfa(c) Rye(d) WheatI had been asked this question in exam.My question is based upon Microbes as Biofertilizers topic in section Microbes in Human Welfare of Biology – Class 12

Answer»

Right choice is (d) Wheat

The best I can explain: Smoother crops do not ALLOW the growth of weeds. For example, Sunflower, SOYBEAN, ALFALFA, Barley, Rye, SORGHUM, Sweet CLOVER. Rotation with smoother crops gives protection from the weeds.
