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.

In order to evaluate the foliar application of zinc sulfate and salicylic acid effects on morphology and yield of safflower Carthamus tinctorius L. ( cv. sofeh) under drought stress in Yasouj, a factorial experiment based on a randomized complete block design with four replications was conducted Yasouj University in 2012. The factors consist of three levels of drought stress, watering at 3 levels of consumption 10%, 30% and 60% of available water, respectively, as the levels of stress, mild stress and severe stress and foliar application in 5 levels, including control, salicylic acid (0.5, 1 and 1.5 Mm) and zinc sulfate (3 g l-1), respectively. The results showed that drought and foliar application interaction for number of heads, the number of fertile seeds per head, seed weight and yield were significant and other traits were non-significant. Drought stress reduced, but foliar application of zinc and salicylic acid increased the grain yield. The highest grain yield per plant at 30% and 60% moisture content were achieved by 0.5 Mm salicylic acid foliar applications. The highest grain yield in plant at 10% (FC) water availability was shown by zinc sulfate the foliar application. At all drought stress levels, the highest grain weight obtained by zinc sulfate foliar application and the highest fertile head number in 10 and 60 percent of water availability related the foliar applied concentration of 1Mm salicylic acid. The highest number of grains per head in 60% water availability belonged to 1.5Mm salicylic acid foliar applications.

In order to study the effects of different levels of sulfur along with Thiobacillus and zinc on qualitative and quantitative growth of canola cv RGS003, a factorial experiment was conducted based on an RCBD with three replications at the Agricultural Research Station of Gonbad in 2013. The first factor was the application of sulfur with Thiobacillus at four levels, i.e. without sulfur and Thiobacillus (S0), 500 kg sulfur ha-1 + 10 kg Thiobacillus ha-1 (S1), 1000 kg sulfur ha-1 + 20 kg Thiobacillus ha-1 (S2) and 2000 kg sulfur ha-1 + 40 kg Thiobacillus ha-1 (S2). The second factor consisted of two levels of zinc: without zinc (control) and 20 kg zinc sulfate ha-1. The results showed that all traits studied were significantly affected by sulfur with the exception of pod length. The effect of zinc was significant at 0.01 probability level of biological yield, seed yield, harvest index, straw yield, oil percent and oil yield. With an increase in application of sulfur mixed with Thiobacillus up to 1000 kg sulfur ha-1 + 20 kg Thiobacillus ha-1 (S2), all yield components increased except oil percent, but their further increase resulted in reduction of seed yield and yield components of canola cv RGS003. With the exception of oil content, the other traits studied were not affected by the interaction of sulfur by zinc.

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).
