The effects of elevated atmospheric NH<sub>3</sub> on growth and yield parameters of two winter wheat varieties, the high water and fertilizer-demanding variety Xiaoyan 6 (XY6) and the drought-resistant variety Changhan 58 (CH58), grown with two levels of N fertilization, were studied in Open-Top Chambers. The results showed that in combination with the high N treatment increasing the atmospheric NH<sub>3</sub> concentration to 1000 nl/l from the ambient level of 10 nl/l NH<sub>3</sub> significantly (<I>P</I> < 0.05) reduced the biomass and the root/shoot ratios of the plants, especially in XY6 plants, mainly because it negatively influenced root biomass production at anthesis and mature stages. In addition, the grain yield of XY6 was by 1.51% higher, while that of CH58 was 13.2% lower, following exposure to the elevated atmospheric NH<sub>3</sub> concentration rather than the ambient concentration in combination with the high N treatment. In contrast, in combination with the low N treatment, elevated atmospheric NH<sub>3</sub> had significantly and non-significantly positive effects on the grain yield of XY6 and CH58 plants, respectively. The Nitrogen Use Efficiency (NUE) and related parameters were all lower in plants of both varieties exposed to the high atmospheric NH3 concentration together with either the high or low N treatment.

A pot experiment was carried at Patuakhali Science and Technology University to study the performance of some BARI wheat varieties under the coastal area of Patuakhali. Four wheat varieties viz. BARI ghom-23, BARI ghom-24, BARI ghom-25 and BARI ghom-26 were planted in the field to evaluate their comparative performance in respect of germination percentage, growth, yield and yield attributing characters. Among the four varieties, BARI ghom-26 showed superior performance irrespective of all parameters studied except total dry matter content (TDM) and yield reduction percentage. Among the BARI varieties, BARI ghom-26 produced greater germination (61.00%) at 13 days judge against to other varieties. The taller plant (47.91 cm), higher LAI (1.84), maximum TDM (17.37 g plant-1) and effective tillers hill-1 (18.08) were also obtained with the similar variety. BARI ghom-26 was also most effective to produce the maximum grains spike-1 (38.52), higher weight of 1000-grains (49.38 g), higher grain (3.35 t ha-1) and straw (8.50 g plant-1) yield and greater HI (4.03%). So, the variety BARI ghom-26 produced the outstanding superiority among the varieties.DOI: http://dx.doi.org/10.3329/jesnr.v5i2.14816 J. Environ. Sci. & Natural Resources, 5(2): 209-212 2012

A field experiment was carried out to study the influence of different irrigation regimes on the panicle and grain growth, relative growth rate of grain, grain abortion, yield and some yield components of four wheat varieties in two growing seasons. Irrigation regimes had significant effects on the aforesaid parameters and the varieties were found to be more efficient under well irrigated conditions. A drastic reduction in panicle and grain growth and yield and increase in grain abortion was noticed when the varieties were grown under rainfed condition. C 306 was found to be the most efficient to have higher values of panicle and grain growth, relative grain growth rate and yield under all the irrigation regimes in both the growing seasons.

Rapid Emergence

In the sub-tropical regions of India, the 1st to 3rd week of November is the optimum time for sowing wheat. A delay in sowing due to various factors causes a substantial yield reduction. Seeds of four wheat varieties (Sonak, UP 2338, Raj 3765 and PBW 343) were subjected to seed priming treatments involving water, salts, growth regulator and the sowing of sprouted seed under late-sown conditions during the winter seasons of 1998-99 and 1999-2000. The sowing of sprouted seeds resulted in significantly more rapid emergence of seedlings, accompanied by higher grain and straw yields. Seeds primed with IAA, KCl, water, ZnSO4 and Na2SO4 followed in this order. The lowest seedling emergence and grain yield were obtained for unprimed seeds. Seedling emergence was higher in the variety Sonak, while Raj 3765 and UP 2338 had higher leaf water, osmotic and turgor potentials during the 1998-99 season. The variety PBW 343 produced significantly higher grain and straw yields in the 1999-2000 season.

Abstract Purpose Salinity pose severe threat to cultivation as it drastically affects the plant sustainability and yield. The intended aim of current consensus is to assess effects of sodium silicate and salicylic acid on wheat genotypes (slat tolerant and salt sensitive) grown under salt. Methods This experiment was designed to check the effect of silicon on wheat varieties, so four different wheat genotypes named as (Umeed, Rasco, Zarghoon and Shahkaar) were grown in hydroponics under saline and normal environment. Sodium silicate and salicylic acid were applied on all varieties to determine the slat tolerance ability. Plants were harvested at maturity and different physical and chemical aspects were recorded. Results To assess the salt stress on growth and yield of wheat genotypes. Wheat grown in saline conditions with sodium silicate supplementation showed improvement in all growth parameters as compared to the plants grown under salt stress without silicon supplementation. Higher contents of potassium were observed in plants grown under salt stress with silicon supplementation however, potassium concentration was found less in salicylic acid treatment and control under salt stress. Sodium concentration was found higher under salt stress but sodium silicate application reduced Na+ uptake under salt stress. Significance increase in K+ : Na+ ratio in roots enhance the translocation which in turn elevates salt tolerance ability. Among wheat varieties potassium uptake was quite high in Umeed and Rasco as compared to Zarghoon and Shahkar. Conclusion Based on current results it can be deduced that application of sodium silicate on different wheat varieties mitigated Na+ toxicity by elevating K+: Na+ ratio and net translocation rate in salt stressed plants.

Wheat (Triticum aestivum L.) is known as a drought semi-tolerant species.Reduction in wheat growth and yield are the most common responses to drought orsalt stress mainly caused by an inhibition of leaf expansion and stem elongation.One of the important abiotic stress factors limiting wheat production in semiaridregions is drought. Recent climate changes such as temperature changes anddecreasing rainfall in different regions of Iran have had significant impact on agroecosystemsand have caused drought stress to become a severe limiting factorin wheat production. This research was conducted for evaluation of leaf anatomicaland cytological traits of 26 wheat varieties in Golestan province (Iran) over 40years in order to identify the most effective traits in determining maximum yieldpotential. The width and length of vascular bundles, diameter of meta xylem,distance between vascular bundles to upper and lower epidermis, fiber bundlesdiameter and width of midrib and lamina were measured. Finally, based on theanatomic results, wheat varieties with the highest adaptation ability to droughtstress were identified and introduced.

A field experiment entitled “Effect of sowing dates on growth, yield attributes and yield of four wheat varieties” was conducted during winter season of 2016-17 on sandy loam soils of Poz-e-Ishan Research Farm of Agricultural Faculty of Baghlan University. The experiment was laid out in split plot design viz. four dates of sowing comprised of (16th November, 01st December, 16th December and 31st December 2016) as main plot treatments and four varieties (Solh 02, Gul 09, Muqawim 09, Kabul 013) as sub plot treatments with four replications. The highest plant height, number of effective per plant, test weight and grain yield of wheat was recorded with all varieties sown on 16 Nov-16, which was statistically identical with all treatments sown on 01 Dec-16 but significantly higher over rest of date of sowing. Among wheat varieties Kabul 013 and Gul 09 produced significantly higher plant height, number of effective per plant, test weight and grain yield of wheat over rest of the varieties.
