The study of effects of pattern planting and seed rate on yield and components yield of Hyola401 in sistan regian

Planting pattern and plant density is more important for yield improvement and yield component. For aspect reach to better of density Form amount of seed and planting pattern in sistan area, one experiment with design of split plot achieved in base randomized complete block design with four replication. In this study planting pattern treatments include : 1- planting pattern of plot 2- furrow of 50cm 3- furrow 60cm while this treatments is mainplot and tree seed amount include 5,7 and 9 kg/ha are subplot and each pubplot contains six planting line to length 5m . Analysis of Variance from firs year showed effect of planting pattern on seed yield , oil yield and flowering period different significant in %1 level and on number of siliqua plant and biological yield had different significant in level %5 . mean compares showed the most yield with mean of 3865 kg/ha belong to furrow 60 cm and the least of seed yield with mean of 3216 kg/ha belong to flate planting pattern.effect of seed amount expect of number plant for each trait Non significant .Results of two years showed planting pattern on yield, height, oil yield, biological yield , Number plant in m2 , period of flowering and grow period had signigicant different in %1 level and on harvest index had signiticant different in %5 . Mean compares showed the most yield belong to planting pattern plot with mean 3649 kg/ha and the least yield with means 2655 amd 2722kg/ha belong to planting Furrow . effect of seed amount study except of harvest index in %5 level and number plant in %1 level for other trait was not significant. Interaction of total of factors in experiment of second year are not significant . Analysis of variance two years ( compound) showed effect of years on w 1000 seed , height , seed yield, oil yield, hieght, biological yield ,number plant in m2 , flowering period, growth period traits was different significant in %1 level .Compares mean showed in total 2 years planting pattern had non significant effect. The planting pattern plot in total 2 years with mean 3433 kg/ha had the most yield. In total 2 yeas amount of seed consuming except of nmber of plant in m2 on each trait Non significant. And interaction effects of factors too except of flowering period on each traits Non significant.. Result of guality of seed in each of years showed oil percent had not changed from this factors study.
