Effect of distances between row, density and cultivation pattern on 704 single crass forage corns with summery dilatory cultivation after harvest rice

This research was done in order to consider the effects of distances between row, density and cultivation pattern of 704 single crass forage corn (K. Sc 704) which was accomplished with summery dilatory cultivation after harvesting of rice. It was done at Gharakhil research center of Ghaemshahr in 2008.The experiment design was selected as factorial based or RCBD with four replications. Treatments were selected as distances between rows (65, 75, 88 cm), two cultivation pattern (single linear row and two zigzag row) and two cultivation density level 70000 and 80000 bush in hectare. Results showed that distances between rows influenced only on wet forage yield, as wet forage yield in 65 cm distance between rows with 25.38% rate was gained more than 85 cm distance between rows. The yield of wet forage in two zigzag row cultivation patterns was %7 rates more than single row cultivation. Corn diameter and single bush dry weight in 70000 bush density in hectare was more than 80000 bushes in hectare. Stem diameter and wet forage yield in two rows cultivation were more than single linear row cultivation. Maximal of stem wet weight rate to all in 70000 bush density in hectare were gained in two zigzag row cultivation. The largest corn length was gained in 65 cm distance between row and two zigzag row cultivation. Maximal of wet forage yield was gained in 65 cm distance between rows with 80000 bush density in hectare.
