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.

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.

Sesame is an oily and medicinal seeds adapted to tropic and semi-tropic regions of the world but cultivation of its new accessions has been developed in temperate regions. To evaluate the effect of plant density on growth indices, seed oil percentage and seed yield of three sesame genotypes, an experiment was conducted as factorial based on a randomized complete block design with three replications in 2014, in Rostam region, Fars, Iran. First factor was planted density at five levels (15, 25, 35, 45 and 55 plant m^-2) and the second factor was three sesame genotypes (Nurabad, Borazjan and Darab 14). The result showed that maximum and minimum LAI was achieved from Nurabad and Darab 14 and also from 15 and 55 plant m^-2, respectively. Growth indices analyzing showed that Nurabad was better than the two genotypes. Maximum CGR ranged from 1.96-2.62 g m^-2 GDD^-1. Nurabad and Borazjan had the maximum RGR at the beginning of the growing season. Plant density decreased oil percentage and Borazjan had the maximum seed oil percentage. Generally, regards to the results, Nurabad with 55 plant m^-2 density performed better than other genotypes in Rostam region. Borazjan in 55 plant m^-2 density can be a good alternative for Nurabad.
