Abstract: 

The research was conducted at the Agricultural Scientific Researches Center in Aleppo during 2020 growing season, to study the effect of water and salt stress in laurel implants in their first phase of age. Two levels of deficit irrigation were applied at 50 and 30% of the field capacity and three levels of salt concentrations 6, 8, 10 ds /m in addition to control treatment (100% of field capacity, 1 ds /m) were applied separately in two experiments, with randomized complete block design (RCBD). The results were taken after two months of applying the treatments, by measuring the longitudinal growth rate of the implants, the number of formed leaves and the leaf area. The results showed that the implants tolerate water stress up to 50% of the water amount which added at field capacity and salt concentrations (6, 8, 10 ds / m), as the longitudinal growth in them reached after two months (2.06, 2.23, 1.93, 1.8 cm) respectively, the number of leaves (3.66, 3, 1,1) respectively, and ​​the leaf area (10.85, 11.59, 10.79, 10.59 cm²), respectively. The laurel implants did not tolerate water stress with 30% of the water amount which added at field capacity, as longitudinal growth stopped completely in the second month, no new leaves were formed in it with most of the old leaves withering, and the leaf area of the non-wilted leaves was 6.51 cm². The control treatment significantly outperformed all treatments two months after the experiment start, with a growth strength of 3.48 cm, leaves number of 3.66 sheets, and leaf area of ​​12.62 cm².

Abstract: 

In this study a field experiment was carried out during the two growing seasons (2013-2014 and 2014-2015) at Al-Tuwaitha Research Station, it is located 30 km southeast of Baghdad, for cultivation of wheat crop in calcareous clay loam soil, and its salinity (10.12 dS.m^-1). Four levels of foliar fertilization were used with calcium at (0, 1000, 2000 and 3000 mgL^-1) named F0, F1, F2 and F3 respectively. Saline water (5.40 dSm^-1) was used to irrigate plants. The results showed a significant increase of K/Na, Ca/Na, and Mg/Na ratio in the wheat leaves as well as the total carbohydrate and proline levels. Also, calcium application significantly affects the dry matter and grain yield of wheat crop, and the increase in the dry matter ranged between 5.18 to 12.20 %, and in grain yield between 12.86 to 26.20 % compared to the control F0. Ca treatment of 3000 mg/L(F3) was significantly superior to other treatments in grain yield of wheat compared without calcium foliar application(F0).This clearly showed the positive and effective role of calcium in osmotic adjustment and increased wheat tolerance to salinity and improve its yield.

Key words: Calcium, proline,  wheat, salt-affected soil.

Abstract: 

A filed experiment was conducted using a complete randomized block design at Jableh-Bustan saleh seasons 2018-2019. The aim was to evaluate the effect of increasing application rates of nitrogen fertilizer as urea (46% N) (N: 0, 100, 200, 300 and 400 kg N/ha) and potassium humate (H: 0, 2.5, 5, and 10 kg H/ha) on growth components and N uptake of bread wheat (triticum aestivum sp. Sham 10). The number of tillers and distribution between fertile and non-fertile, main and tiller stems height, spike length, and straw yield were recorded. N concentration in straw was determined, and N uptake was calculated. The results of statistical analysis showed a significant effect of nitrogen application on number of tellers, plant height, and spike length. The production of hay was increased from 3.73 ton/ha in the control (N0) to 14.77, 20.46, and 25 ton/ha with increased N application from 100, 200, 300 kg N/ha respectively. There was no increase in hay production with application of 400 kg N/ha. The application of humate alone (2.5, 5, and 10 kg/ha) led to a gradual increase in hay yield (from 3.73 in H0 treatment to 7.33, 8.5, and 10.66 ton/ha, respectively), and N removal (from 31 to 78, 95, and 125 kg N/ha, respectively). The results also showed an improvement of N treatment up to 300 kg N/ha with 2.5 kg H/ha over those treatments with N application alone in growth parameters, hay yield, and N removal by hay. Increasing application of humate to 5 and 10 kg/ha didn’t show any significant effects on growth parameters or hay yield.
