Average yeild per acre depends on lots of factors-seeding rate 18,000-22,000 seeds per acre, is it irrigated, insect pressure (less in June/JUly, greater in August and September),& nutritional factors.xcellent yield on irrigated land 1400-1500 dozen (seed rate 20-21,000) per acre, , average 1200 dozen and fair yield 1000 dozen. Yield will decrease 100-200 dozen per acre due to insect pressure later in season. Price is another variable.
