Abstract

Effects of plant density (row intervals and plant distances) on the yield and yield components of a single cross corn named 711 were studied in Mianeh region, Azarbayejan-e-Sharqi Province, Iran. The experiment was a factorial based on a randomized block design with four replications and was carried out in Agricultural Research Station of Islamic Azad University, Miyaneh Branch, in 2005. Factors of the experiment consisted of three row intrevals of 45, 60 and 75 cm and three poulations of 50000, 65000 and 80000 plants per hectare. At the occasion of physiological maturity, when the moisture content of seeds reached to 14%, the yield was harvested. Yield and yield components such as WEIGHT OF 1000 SEEDS, stem weight, EAR weight, biological weight (TDW), HARVEST INDEX, number of seeds and EARs per row were meatured. The results of variance analysis showed essential differences between row intervals indicating that by increasing row distances, WEIGHT OF 1000 SEEDS, stem weight, biological weight, number of seeds in each row were significantly increased at 5% of probability level; but other characters were not affected by row intervals. Increasing plant poulation was accompayning with a significant shift of biomas weight, HARVEST INDEX and yield (P<5%), but WEIGHT OF 1000 SEEDS, stem weight, EAR weight and number of seeds in each row significantly decreased. Row intervals of 60 cm in combination with plant poulation of 65000 /ha produced the highest yield (13080 kg/ha) and 75 cm row interval with 50000 plant poulation produced the lowest yield (8154 kg/ha) among the treatments.
