It was found that Saratovskij out-yielded Sunfola in grain yield, good seed weight, 100 good seed weight, size of head and plant height. Single row/ridge planting produced good seed weight, 100 good seed weight, size of head and plant height better than double rows/ridge, but the latter gave more grain yield than the former. Spacing between plants at 6.25 cm apart produced better grain yield, good seed weight, 100 good seed weight, and size of head than those at 12.5 and 25 cm apart. Both varieties demonstrated significant gave responses to N fertilizer at 100 and 50 kg/ha. Authors
