In order to study the effect of foliar application of zinc and iron on yield quantity and quality of canola (Brassica napus cv. Talaye) an experiment was conducted in Zarghan region of Fars in 2008- 2009 crop season. Iron and zinc solutions were sprayed twice (first in stem elongation and then in early flowering) treatments, including concentration of zinc sulfate in three levels: (0, 2, 4 gr lit-1) and Iron sulfate in three levels: (0, 2, 4 gr lit-1). This experiment was arranged as factorial using randomized complete block design in four replications. Significant interaction between zinc and iron foliar application was observed for grain yield, seed protein percentage and oil yield. Maximum grain yield (4905.3 kg ha-1), Seed protein percentage (37.7%) and oil yield (2124.5 kg ha-1) was obtained from foliar application of combined zinc and iron at 4 g lit-1. Increasing of zinc from 0 to 4 gr lit-1 significantly increased 1000 seed weight (from 4.24 to 4.69 gr), number of seed per pod (from 19.12 to 22.88), seed oil percentage (from 38.67 to 43.17) and seed zinc concentration (from 33.28 to 22.07 mg kg-1). Increasing iron from 0 to 4 gr lit-1 significantly increased 1000 seed weight (from 4.24 to 4.64 gr) and seed iron concentration (from 64.29 to 79.18 mg kg-1). Finally, with respect to this research, foliar application of zinc and iron sulfate together and twice, at 4 g lit-1 was suggested to get more quantity and quality of canola (Talaye) in Zarghan.

A field experiments was conducted at Sabzevar Agriculture & Natural Resources A field experiments was conducted to study the effect of zinc sulfate foliar application on yield and yield components of sunflower, Haysun-25 cultivar (Helianthus annuus L.) under drought stress at Sabzevar Agriculture & Natural Resources research center. This experiment was carried out (conducted, deleted) as split plot based on randomized complete block (RCB) design that main and subplot factors were drought stress levels [Non-stress, Moderate and High drought stress (6, 12 and 18 day’s irrigation interval, respectively] and foliar zinc applications (0, 5, 10 and 15‰), respectively. Foliar application of zinc was performed in 6 to 8 leaf stage of sunflower. Plant height, seeds per head, hollowness percentage seeds, 1000 seed weight, grain yield and biological yield were significantly affected by drought stress. Severe drought stress decreased plant height, seeds per head, 1000 seed weight and economic yield and increased percentage of empty seeds. The highest yield and yield components were related to foliar application with 15‰ concentration of zinc sulfate and the lowest one was related to the control. However, yield response to zinc sulfate foliar application was more in non-stress condition, but zinc sulfate with 15‰ led to decrease of negative effects of drought stress. Overall, the highest yield was obtained by spraying with concentration of 15‰ zinc sulfate and non-stress condition.

Niger seed (Guizotia abyssinica Cass.) is a multipurpose plant that has imported to Iran as a bird seed and doesn't have any scientific report in Iran. In order to evaluate the agronomic and physiological characters of Niger seed (as an oil seed and medicinal plant) in different seasons and sowing dates, some acts such as authentication of this species was done. Niger seed has been sown in autumn, spring and summer. Also in summer the effect of sowing date in a completely randomized design with 4 replications and 3 treatments (9 June, 21 June and 3 July) was evaluated in Isfahan province in 2010. According to the results, autumn and spring were not suitable season of cultivation of this plant and it can be grown in summer successfully. The effect of various summer sowing date, on most of the measured traits were significant. The best planting date was about the third planting date in Isfahan climatic conditions. The highest value of the number of capitula per plant (59.07), 1000 seed weight (3.39), seed yield per hectare (874.7 kg), number of seeds per plant (1510), seed oil (47.33) were obtained from the third sowing date. While the highest plant height (150.1cm), days to 50% flowering (67), days to 80% maturity (110) was recorded from the first sowing date.

In order to evaluate the effects of zinc foliar application, Rhizobium inculation and phosphorus solublizing bacteria on soybean cv. Katul an experiment was carried out as a factorial arrangement, in an RCBD with three replications at Deland (Golestan province) in 2015. The factors comprised of zinc spraying at three levels (without spraying, 1.5 and 3 g L-1 zinc sulfate), inoculation with R. japanicum at two levels (with and without inoculation), and inoculated with phosphorus solublizing bacteria at two levels (with and without inoculation). The results revealed that the effects of phosphor solublizing bacteria were significant for plant height, stem diameter, number lateral branches, pod length, number of seeds per pod, number of pods per plant, 1000 seed weight, grain yield and oil per cent. Seed inoculation with Rhizobium significantly affected all trails studied with the exception of protein content and pod length, Zinc significantly affected grain yield, oil and protein content. The seed yield of psb treatment had significantly higher yield (2954 kg/ha) compared to seed yield (2752 kg/ha) of non-incolation. Also, spraying with zinc at 3g/li had significantly higher yield (2990 kg/ha) than that of without sprying yield (2648 kg/ha).
