Summary
The extent of natural cross-pollination in Egyptian clover cultivated in Punjab, India, varied from zero to 4.73% in all the three different sowing arrangements. The high out-crossing percentage in the alternate plant (1.57%) and the concentric circle arrangement (1.6%) was due to the close proximity of the pollen source and the abundant pollen supply.
