Abstract

The effect of PLANTING PATTERN and PLANT DENSITY on growth, physiological index, forages and grain yield of two maize hybrid including single cross 704 and three way cross 647 were studied in a factorial experiment in a randomized complete block design with three replications at experimental farm of faculty of agriculture of Tehran University in year 2000. PLANTING PATTERN treatment was include normal planting and two rows planting on the wide ridge (every other furrows removal) and PLANT DENSITY treatment incased 70000, 80000 and 90000 plant per hectare. The results of experiment showed that grain yield, forage yield and total dry matter accumulation were increased with increasing of PLANT DENSITY and PHYSIOLOGICAL INDEXES including leaf area index, crop growth rate and leaf area duration increased and net assimilation rate decreased and greatest amount of grain and forage yield obtained in 90000 plant/hectare densities. PLANTING PATTERN treatment had a very significant effect on grain and forage yield and the greatest amount of grain and forage yield and PHYSIOLOGICAL INDEXES including leaf area PLANTING PATTERN. Among the two corn cultivar, the single cross 704 has higher grain and forage yield and total dry matter accumulation than three ways cross 647 and there was a negligible differences in PHYSIOLOGICAL INDEXES of two cultivars.
