The quantity and quality of performance of intercropping of forage sorghum with soybean and green bean were studied through factorial experiment (randomized complete block design) with 4 replications at Agricultural Research Center of Iraqe, Gorgan. The first factor planting pattern included: sorghum, green bean, soybean, one row sorghum + one row green bean, one row sorghum and one row soybean, two rows sorghum and one row green bean, two rows sorghum and one row soybean, one row sorghum and

... o rows green bean, one row sorghum and two rows soybean, and the second factor planting density included, optimum density (250000 Sorghum plant/ha+40000 legume plant/ha) and plant density more than 20% (300000 sorghum plant+480000 legume plant/ha). The results showed a significant difference in patterns of all traits in legumes and sorghum cultivation and number of leaves and stem diameter of Sorghum, in 1 line Sorghum and 2 line soybean patterns was higher than other treatments. In treatment of soybean with high planting density (31200 kg/ha) and one row sorghum and two rows Soybean (30392 kg/ha) the yield of forage were highest. The treatment of two rows Sorghum and one row green bean had a highest land equivalency ratio (LER= 1.6). ‫ﻣﻘﺪﻣﻪ‬ ‫ﺑﻪ‬ ‫ﻃﺒﯿﻌﯽ‬ ‫ﻗﻮاﻧﯿﻦ‬ ‫ﺑﻪ‬ ‫داﺷﺖ‬ ‫ﭼﺸﻢ‬ ‫ﮐﺸﺎورزي‬ ‫ﻋﻠﻮم‬ ‫در‬ ‫ﺷﮑﻞ‬ ‫آن‬ ‫ﻧﻤﻮﻧﻪ‬ ‫ﮐﻪ‬ ‫اﺳﺖ‬ ‫ﺷﺪه‬ ‫ﻣﺘﺠﻠﯽ‬ ‫ﻣﺨﺘﻠﻔﯽ‬ ‫ﻫﺎي‬ ‫ﻣﯽ‬ ‫ﭘﺎﯾﺪار‬ ‫ﮐﺸﺎورزي‬ ‫از‬ ‫ﺗﻠﻔﯿﻘﯽ‬ ‫ﭘﺎﯾﺪار‬ ‫ﮐﺸﺎورزي‬ .‫ﺑﺎﺷﺪ‬ ‫ﻣﯽ‬ ‫ﮐﻪ‬ ‫اﺳﺖ‬ ‫ﻣﺪﯾﺮﯾﺖ‬ ‫داﻧﺶ‬ ‫ﻧﻈﺮ‬ ‫از‬ ‫ﻣﺪت‬ ‫ﺑﻠﻨﺪ‬ ‫در‬ ‫ﺗﻮاﻧﺪ‬ ‫اﻓﺰدوه‬ ‫ارزش‬ ‫اﻗﺘﺼﺎدي‬ ‫و‬ ‫ﻣﺤﯿﻄﯽ‬ ‫زﯾﺴﺖ‬ ،‫ﺑﯿﻮﻟﻮژﯾﮑﯽ‬ ‫داﺷﺘ‬ ‫ﻫﻤﺮاه‬ ‫ﺑﻪ‬ ‫ﻣﻄﻠﻮﺑﯽ‬ ‫ر‬ ‫از‬ ‫ﯾﮑﯽ‬ .‫ﺑﺎﺷﺪ‬ ‫ﻪ‬ ‫ا‬ ‫ﺣﺮﮐﺖ‬ ‫ﻫﮑﺎرﻫﺎي‬ ‫از‬ ‫ﻣﺨﻠﻮﻃﯽ‬ ‫ﮐﺎرﮔﯿﺮي‬ ‫ﺑﻪ‬ ،‫ﭘﺎﯾﺪار‬ ‫ﮐﺸﺎورزي‬ ‫ﺳﻤﺖ‬ ‫ﺑﻪ‬ ‫اﯾﺰوﻻﯾﻦ‬ ‫ﯾﺎ‬ ‫و‬ ‫ارﻗﺎم‬ ،‫ﻣﺨﺘﻠﻒ‬ ‫ﮔﯿﺎﻫﺎن‬ ‫در‬ ‫ﻣﺨﺘﻠﻒ‬ ‫ﻫﺎي‬ ‫ﻣﯽ‬ ‫زراﻋﺖ‬ ‫ﻫﻤﮑﺎران‬ ‫و‬ ‫)ﺟﻮاﻧﻤﺮد‬ ‫ﺑﺎﺷﺪ‬ 1392 ، ‫ﻫﻤﮑﺎران‬ ‫و‬ ‫اﺳﺘﺮاﯾﺪﻫﻮرﺳﺖ‬ 2008 .(‫ﻣﺨﻠﻮط‬ ‫ﮐﺸﺖ‬ ‫ﺑﻪ‬ ‫دﻟﯿﻞ‬ ‫ﻣﯽ‬ ‫ﮔﯿﺎﻫﯽ‬ ‫ﺗﻨﻮع‬ ‫اﻓﺰاﯾﺶ‬ ‫ﺗﻮاﻧﺪ‬ ‫ﺑﻪ‬ ‫ﻋﻨﻮان‬ ‫روش‬ ‫ﯾﮏ‬ ‫زراﻋﯽ‬ ‫ﮐﺸﺎورزي‬ .‫ﮔﺮدد‬ ‫آﻓﺎت‬ ‫ﺧﺴﺎرات‬ ‫ﮐﺎﻫﺶ‬ ‫ﺑﺎﻋﺚ‬ ‫ﻋﻮاﻣﻞ‬ ‫ﺣﺪاﮐﺜﺮ‬ ‫از‬ ‫اﺳﺘﻔﺎده‬ ‫ﭘﺎﯾﻪ‬ ‫ﺑﺮ‬ ،‫ﻧﯿﺰ‬ ‫اﯾﺮان‬ ‫ﺳﻨﺘﯽ‬ ‫در‬ ‫ﮐﯿﻔﯽ‬ ‫و‬ ‫ﮐﻤﯽ‬ ‫ﻋﻤﻠﮑﺮد‬ ‫ﺑﺮرﺳﯽ‬ ‫ﻋﻠﻮﻓﻪ‬ ‫ﺳﻮرﮔﻮم‬ ‫ﻣﺨﻠﻮط‬ ‫ﮐﺸﺖ‬ ‫ﺳﺒﺰ‬ ‫ﻟﻮﺑﯿﺎي‬ ‫و‬ ‫ﺳﻮﯾﺎ‬ ‫ﺑﺎ‬ ‫اي‬ 117
