Abstract

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.

Abstract

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.

Abstract

In order to evaluate the effect of different levels of humic acid on some quantitative and qualitative traits of cotton a factorial field experiment in a randomized complete block design with three replications was conducted in Kashan under salinity soil condition in 2013.Treatments included three cotton cultivars of Varamin, Line 43200 and Khordad as first factor, and six foliar ‌treatment included without humic acid and chemical fertilizer‌ (T1), without humic acid with chemical fertilizer (T2), 3 l/ha humic acid without chemical fertilizer (T3), 1 l/ha humic acid with chemical fertilizer (T4), 3 l/ha humic acid with chemical fertilizer (T5), and 6 l/ha humic acid with chemical fertilizer (T6).The results showed that humic acid significantly increased oil and protein content, yield, seed yield, fiber yield and 1000 seeds weight. In T5 treatment, gin, lint, and grain yields, 1000-grain weight, and oil content increased by 32.74%, 31%, 33.69%, 5.32%, and 2.7%, respectively. Using 3 liters of humic acid without the application of chemical fertilizer increased seed protein yield by 63.4%.
