A factorial experiment with randomized complete block design carried out in Erbil governorate, Iraq during 2015 and 2016 seasons on pear (Pyrus Communis L.) Spadona and Compote cvs. to investigate the effects of spraying trees with (0, 0.5, 1.0 and 1.5%) salicylic acid (SA) on some fruits quantity and quality characteristics. The results show that Compote fruits had the highest weight and firmness significantly compared to Spadona fruits in both seasons, whereas Spadona variety records the highest total acidity. Fruits of Compote variety records higher chlorophyll a , chlorophyll b and total carotenoids content significantly compared to Spadona variety in 2015, in the opposite of the results of 2016 in respect to chlorophyll a and chlorophyll b. Spraying trees with SA increased fruit weight and firmness compare to control treatment for both seasons, and total acidity in 2015 and total sugars in 2016, whereas the differences were not significant in 2016 and 2015 for the last two properties. In 2015 spraying 1.5% SA increased each of chlorophyll a and b content significantly compared to other concentrations, whereas significant decrease in total carotenoids content observed with increasing SA concentration, whereas the differences between SA treatments were not significant in 2016 in respect to chlorophyll a, b and total carotenoids.

The response of active ingredient, chlorophyll a and b contents, and chlorophyll index of henna to different rates of N fertilization and drought stress was explored in a split-split-plot experiment based on a randomized complete block design with four replications in the research farm of Jiroft Branch, Islamic Azad University, Jiroft, Iran in the 2016-2017 growing season. In the current study, the main plot was assigned to drought stress at three levels (including irrigation to supply 100%, 75% or 50% of plant water requirement), the sub-plot was assigned to N fertilization at three rates (50, 100 or 150 kg ha-1 pure N), and the sub-sub-plot was assigned to ecotype at three levels (Bami, Bushehri, and Rudbari). The results showed that the effect of drought level was significant on active ingredient and chlorophyll index at the p < 0.01 level and on chlorophyll a, total chlorophyll, and chlorophyll a/b ratio at the p < 0.05 level.  But, it could not influence chlorophyll b significantly. The effect of N fertilization was significant on most studied traits at the p< 0.01 level, but its effect was significant on the chlorophyll index at the p < 0.05 level and insignificant on dye and chlorophyll b. According to the results, it seems that the application of 100 kg ha-1 N and the irrigation to supply 75% of plant water requirement can contribute to having more fresh plants with the higher active ingredient and dye contents.

The experiment was conducted to study the effect of salicylic acid (SA) as foliar spray on yield and yield contributing characters of BRRI Hybrid dhan3.The experiment was laid out in a randomized complete block design (RCBD) with three replications and six treatment combinations as, T1: 0 μM SA, T2: 200 μM SA, T3: 400 μM SA, T4: 600 μM SA, T5: 800 μM SA and T6: 1000 μM SA. The results revealed that biomass production, dry matter production and yield and yield contributing characters were significantly increased due to the foliar application of SA. At the maximum tillering (MT) stage, the highest biomass production (15.0 t/ha) and dry matter production was observed in T3 treatment. Treatments T4, T5 and T6 showed significant variation on the effective tillers/hill. The maximum effective tillers/hill were found in the treatment T6. The percentages of spikelet sterility were decreased with increasing the level of SA and the percentage of filled grains/panicle were increased with increasing level of SA. The insect infestation was reduced with increasing level of SA to up to 1000 μM. The maximum grain yield (9.21 t/ha) and straw yield (9.22 t/ha) was found in the treatment T6 which was identical to T5. On the other hand, in all cases the lowest results were found in the control treatment. The result showed that grain yield of rice increased with increasing level of SA to up to 1000 μM (T6 treatment). Our results suggest that foliar spray of SA might be applied to increase the yield of hybrid rice in Bangladesh.Res. Agric., Livest. Fish.4(3): 157-164, December 2017

Objective of this study was to examine and evaluate the role of different rates of salicylic acid (SA) as foliar spray on growth and yield performance of BRRI dhan29. The experiment was conducted at Sher-e-Bangla Agricultural University, Bangladesh from November, 2016 to May, 2017 following a randomized complete block design with five rates of SA in six replications. The results showed that the lower rate of SA (upto 0.75 mM) has a positive effect on rice biomass production including effective tiller per hill, filled grain per panicle, grain yield and straw yield. The highest dry matter production at both maximum tillering and panicle initiation stages was found at SA spray rate of 0.5 mM. The highest number of effective tillers per hill (14.7) as well as the highest filled grain (120.4) and grain yield (8.1 t/ha) were found at SA rate of 0.75 mM. However, the maximum biomass production was obtained at SA rate of 0.25 mM. The minimum grain yield (7.0 t/ha) was observed in the control treatment.

Background: Prunus microcarpa C.A. Mey. subsp. Tortusa (MK), a wild deciduous plant species, is native to Caucasus and West Asia and grows in a dry temperate climate zone. The plant is mainly used to obtain a dark greyish green dye from its leaves and it has an economic value due to ornamental characteristics. Therefore, this study aimed to determine the appropriate Polyethylene Glycol 8000 (PEG) doses for early detection of drought resistance using MK, SL-64, Garnem, Pixy and Gis-6 rootstocks.Methods: The microshoots of each rootstock were planted at the end of the fourth subculture in Magenta GA7 vessels containing NRM medium. The medium contained 1.0 mg L-1 BA + 0.01 mg L-1 IBA supplemented with 30 g L-1 sucrose, gelled with 5.5 g L-1 agar and 0, 2, 3 and 4% PEG doses (four treatments). The cultures were kept at 23±2 °C temperature under 16 h light (80 μmol m-2 s-1) and 8 h dark photoperiod.Result: The highest number of shoots was recorded in control treatment for MK rootstock (2.81 shoots plant-1) and in 4% PEG treatment for Gis-6 rootstock (2.81 shoots plant-1). Mean chlorophyll a (10.66 mg/f.w) and chlorophyll b (3.63 mg/f.w) contents in the control treatment were lower compared to the mean chlorophyll a (2.03 mg/f.w) and chlorophyll b (1.15 mg/f.w) contents of plants grown in PEG 4% dose. Prunus microcarpa genotypes of Turkey origin tested in this study could be used as potential rootstocks in arid and semi-arid region as safe as the other standard rootstocks tested.
