Abstract

To examine the effects of plant densities and SOWING PATTERN on yield and agronomical characteristics of CORN Hybrid S.C704, a field experiment was conducted in 2004 and 2005 at Agricultural Research Center of Gorgan. This experiment was laid out in a randomized complete block design arranged in a split plot with four replications for two years (2004- 2005). Plant densities (D1=65000, D2=75000, D3=85000 and D4=95000) were as main plot and SOWING PATTERNs (P1=Single row, P2=double row with 15 cm space and P3= double row with 20 cm space) were as subplots. The result of combined analysis over two years showed that by increasing PLANT DENSITY, trait such as GRAIN YIELD, forage yield, ear height, leaves, steam, ear and cob dry matter increased. But characters such as number of grain in ear, ear diameter, ear length, kernel weight, husk dry matter, number of kernel in row and harvest index decreased. Most characters such as GRAIN YIELD, forage yield, leaves, steam, ear, ear cob dry matter, total kernel per ear, ear diameter, ear length, kernel weight and number of kernel per row were increased by changing of planting pattern from single row to double row. PLANT DENSITY and planting pattern interaction effect were significant at 1% level in GRAIN YIELD and forage and 15 centimeter double row, 85000 PLANT DENSITY traits with 14170 kg ha-1 produced the highest GRAIN YIELD. The highest BIOMASS (23330 kg ha-1) was produced on 15-centimeter double, 95000 PLANT DENSITY trait treatment. Also kernel weight, number of grain in row, harvest index, ear high, ear length, leaf, stem, ear, cob and husk dry weight also significant at 1% level. The difference in number of grain in ear, husk dry weight, ear diameter, number of row grain in ear, was significant at 5% level. It was concluded that by using double planting pattern, the inter plant competition was decreased and we could get high yield.
