Abstract

In order to study effects of different levels of nitrogen and plant density on yield and components of Sweet corn (hybrid SC 403), a field experiment was conducted at Ramin University of Agriculture Natural and Resources. Experiment was carried out as factorial design arranged in, randomized completely blocks design with 3 replications. The treatments were three levels of nitrogen (100, 150 and 200 kg ha-1) and three levels of plant density (85000, 70000 and 55000 plants ha-1 ) Grain yield, dry matter yield, wet cob yield, kernel number in row, kernel number row, 1000 grain weight, cob length, cob diameter, harvest index (HI), and grain protein contents were determined The results showed that effect of nitrogen was significant on all traits. The highest grain and wet cob yield (6. 39 and 24. 78 t per ha-1 ) and the highest of grain protein percentage (14. 16%) was obtained with 200 kg/ha-1 nitrogen. The highest kernel number per row, kernel number per row, 1000 grain weight, cob length, cob diameter and harvest index (HI) were obtained with 200 kgha-1 of nitrogen. The effect of plant density was significant on all traits. The highest grain and wet cob yield (5. 96 and 24. 81 t ha-1 ) were obtaned with 85000 plant per ha but the highest grain protein percentage was obtained with 55000 plants per ha. The interaction between nitrogen and plant density was significant for Grain yield, dry matter yield and cob length. and highest dry matter yield (760. 46) was significant 200 kgha-1 nitrogen and plant density 85000 plant per ha. significant 200 kgha-1 nitrogen and density 55000 plant per ha highest cob length (24. 60 cm).
