بررسی کشت مخلوط ذرت شیرین و سویا در الگوها و تراکمهای مختلف کاشت به منظور تولید بلال و علوفه سیلویی

In order to find essential information for effect ire management of corn fields in sole cropping and in the cropping , this experiment conducted in form of random complete blocks and factorial with four replication during ,2 years. Studied treatment are in clouding density in 3 lerel5 (55, 65 and 75 thousands shrub in hectares for soybean)and planting pattern in 5 level 5 , 1: Sole cropping of corn. 2: Sole cropping of soybean, treatments of Compound, imprinting additive. 3: A single row furrow of corn, A single row furrow of soybean. 4: Double rows furrow of corn, double rows furrow of soybean. 5: Corn and soybean are on the double rows furrow. each treatment planted in 6 furrows with 6 meter height which harvest (in milk- dough stage of corn and soybean seed)and statistic calculations done from 4 middle line of each. density and planting pattern intraction effects , had certain effect on corn seed function, protein amount ,, leaf wet weight, stem wet weight and stem size . And function of seed in 75 thousands density shrub in hectare and sole cropping pattern (1.824 tons in hectare). The must production amount was seen by study of these two factors effect. The most size of stem (23.86) achieved by 55 thousands shrub density in hectare for sole cropping which lead to most number of secondary branch ,knob number, stem size. And number of sheath in one row planting pattern of soybean bye two rows planting pattern of soybean and corn .the tallest shrub height(100Cm) achieved by two rows planting pattern of corn and soybean and most distance of internodes is made by 2 rows furrow planting pattern of corn and soybean. Most soybean wet forage made bye soybean sole cropping planting pattern 24.76 ton in hectare. In study of density effect in planting pattern big deference's was seen about all features (except the height). In study about number of secondary branches, sheath and knob, the most number is made by intercropping planting pattern: one row corn, one row soybean with 380 thousands shrub in hectare furthermore the most amount of soybean sole cropping treatment with 475thousand shrub density in hectare . harvest and statistic calculations was done from 4 was done by F test and MSTAT-C and comparison of features mean done by Don ken test. 1.
