Abstract
Bio fertilizers effects were studied on growth and yield of canola in Sistan and Balochistan province. An experiment was conducted in a randomized complete block design with three replications. Treatments included bio-fertilizers at eight levels (not inoculation, phosphate bio-fertilizer (barvar2), Nitro Kara, Bio sulfur, phosphate bio-fertilizer (barvar2) +Nitro Kara, Nitro Kara+ Bio sulfur, phosphate bio-fertilizer (barvar2) + Bio sulfur and phosphate bio-fertilizer (barvar2) + Nitro Kara + Bio sulfur). The results showed that bio fertilizers had no significant effect on the seed number per siliques, number of siliques per plant, seed yield, 1000 seed weight, biological yield, seed of sodium and Plant height but significant different on seed of potassium. The combined use of bio fertilizers also was statistically superior to not inoculation treatment. However, the highest yield was got from Nitro Kara + Bio sulfur but no significant different with other treatments. It seems using of inoculation of Nitro Kara + Bio sulfur produced suitable yield compared to not inoculation (31% greater).
Highlights
Canola is a member of the Brassicaceae family and has become one of the most important sources of vegetable oil in the world

Plant height in inoculation with each of the bacteria compared to non inoculation treatment was no significantly different
Summary
Canola is a member of the Brassicaceae family and has become one of the most important sources of vegetable oil in the world. In addition to oil production, the leaves and stems of canola provide high quality fodder. Matter because of their low fiber and high protein content (Wiedenhoeft & Bharton, 1994). Canola (Brassica napus L.) is one of the main oil crops in many countries especially in Canada, European Union and USA. Nitrogen plays vital role in its healthy growth and is one of the main precursors of protein which absorbs in the form of mineral, ammonium or nitrate by canola plant (Hopkins & Hunter, 2004). N2-fixing maybe important for plant nutrition by increasing N uptake by the plants and playing significant role as plant growth promoting rhizobacteria (PGPR) in the bio fertilization of crops. The aim of this study was directed to investigate the effect of Bio fertilizers on the productivity of canola in sistan region
