The use of organic fertilizers and biofertilizers as alternatives to chemical fertilizers and recognizing the best planting time is a way to improve plant growth and achieve proper yield in agricultural production. In order to investigate the planting date and different nitrogen sources on yield and yield components of two experimental black seed masses in two cropping years 1396-97 and 1397-98 as a factorial split plot in a randomized complete block design with three replications in the experimental field of Azad University Shushtar Islamic was performed. Nitrogen sources include: urea, cow manure, Azotobacter, urea + cow manure, urea + Azotobacter, Azotobacter + cow manure, urea + Azotobacter + cow manure and planting date 1 Azar and 25 Bahman as factorial as the first factor in the main plots and 2 black seed masses Arak. And Semirom were implemented as the second factor in the subplots. Combined analysis of variance showed that the interaction of planting date, nitrogen sources and black seed masses on traits: plant height, number of lateral branches, number of capsules per plant, number of seeds per capsule, 1000-seed weight, grain yield and harvest index at level five . The percentage is significant. In terms of quantity, Arak black seed mass with the highest plant height of 76.4 cm, number of lateral branches 6.4, number of capsules per plant 10.8, weight of 1000 seeds per 1.8 g / m2, biological yield 2218 at surface height Harvest index of 28.3% on the first planting date (November 1) was superior to Semirom black seed mass and the second planting date (February 16). The highest grain yield of 499.8 weight per field was obtained in the treatment of planting date of 1 Azar and application of urea for black seed in Arak, which was significantly different from the combined feeding treatment (urea + Azotobacter + manure) with an average of 460.8 weight in the ground. , Semirom mass did not have on the date of planting 25 Bahman, so according to the results of the selection of Arak black seed mass, the first planting date and integrated feeding is recommended for cultivation in the region.
