Investigation of plants density an sore agronpmic characterishics of Indian mustard under the different irrigation regimes

In order of investigation of sprigs aggregation on some agronomic character rustics of Indian mustard under the different irrigation regimes, on experiment has take place with four replication in shahriar. Aggregation element was considered in three levels including 60, 80 &120 plants in square meter & imitation element in four levels including normal irrigation (control), irrigation cutting in forming stem stage, irrigation cutting in flowering stage & irrigation cutting in running to seed stage. The results has shown that the main effects of irrigation, plants density & reciprocal effects of those on seed yield, biologic yield, harvesting index & seed oil yield was punctuated in %1 level of probability, the maximum seed yield was relevant to the reciprocal effect of normal irrigation in density of 60 plant in square meter with average of 4330 kilograms per hectare. The maximum biologic yield was relevant to the reciprocal effect of normal irrigation in density of 60 plant in square meter with average of 17104 kilogram per hectare. the maximum harvesting index was relevant to the reciprocal effects of normal irrigation in aggregation of 60 springs in square meter with average of 25.3% & the maximum seed yield was relevant to the reciprocal effect of normal irrigation in density of 60 plant in square in square with average of 1851 kilograms per hectare.
