Abstract
In order to find the best planting pattern of soybean (#Glycine max L. Merill) with #sorghum (Sorghum bicolor
L.) intercropping, this research
performed in Gorgan and Aliabaad. Experiment compared on three levels
inform of pure sorghum with density of 250000 plant per hectare,
#intercropping of sorghum and soybean with density of 250000 and 400000
plant per hectare, respectively and intercropping of sorghum and
soybean with density of 300000 and 480000 plant per hectare,
respectively. The number of planting lines was 60 liens with length of
66.66
meters and 50cm interval. For measuring of plant height, number of
tiller, stem diameter and number of node, 10 bushes randomly harvested
by using quadrate. By the way total surface area based of project
protocol also #harvested. For the results analysis t-test applied. Fresh
forage
production at treatment of intercropping with 300000 and 480000 plant
density for sorghum and #soybean, respectively in Gorgan %33.33
and in Aliabad %34.32 had priority compared to check treatment (sole
cropping of sorghum with density of 250000 plants per hectare). Mean
comparison of dry forage also indicated %24.01 increasing in Gorgan and
%26.12 in Aliabaad.
