This work was conducted as a pot experiment, to evaluate the effect of adding K, Fe, Zn, and Mn with conventional fertilizers on K/Na, Ca/Na and Mg/Na ratios and Catalase enzyme activity in leaves and on growth and yield of wheat (Triticum aestivum L.) under salinity conditions. K was added solely with conventional fertilizer dose (F1). In the second treatment, K, Fe, Zn, and Mn were sprayed on the plant as a foliar application before heading stage (F2). In the third treatment, K, Fe, Zn, and Mn were applied to the soil with conventional fertilizer dose (F3). Control treatment (F0), at which only conventional fertilizer dose was applied, for comparison. The field was irrigated with saline groundwater of 4.30 dS m-1. Results showed that leaves K/Na, Ca/Na, and Mg/Na ratios as well as dry matter (F2) and (F3) treatments. Grain yield was increased by 29.60%, 31.52%, and 27.46% under F1, F2, and F3 treatments compared to that of control, respectively. Catalase activity under (F1) treatment was three times over that of control. The results suggested the importance of K and micronutrient fertilization when wheat is grown in salt-affected soil or irrigated with moderately saline water.

A field experiment was carried out in 2019/2020 growing season in Wasit governorate to study the effect of soil mulching with wheat crop residues (control and mulch), three levels of phosphorus (0, 120 and 240 kg ha-1) and four concentrations of humic acid (0, 1000, 2000, and 3000 mg l-1) and their interaction on vegetative growth and green pods yield of broad beans. Split-split plots arrangement within a randomized complete block design with three replications was used. The experimental unit was 6 m2 with a length of 2 m and a width of 3 m. The seeds of broad bean (Semillas Fito variety) were seeded in hills 25 cm apart on lines 50 cm apart, on October 5, 2019. The results showed that soil mulch and the addition of the phosphorus level (240 kg ha-1) led to a significant increase in all characteristics studied (plant height, number of leaves, leaf area, leaf area index, number of branches, pod weight, and green pods yield) compared to the control treatment. Humic acid spraying at 2000 mg l-1 caused a significant increase in plant height, leaf area, and leaf area index. The interaction between the factors also caused a significant increase in leaf area, leaf area index, plant branches number, pod weight, and green pods yield to 2108 cm2, 1.687, 11,300, 17.99 g, and 15.13 t ha-1, respectively, compared to the control treatment.

The current study was carried out to investigate the effect of different benzyl adenine concentrations in culture medium on the axillary buds response of ‘Arma’ tulip cultivar to shoot multiplication in addition to the number of lateral shoots per explant, the number of leaves per shoot, and the length of shoots. For this purpose, Murashige and Skoog medium was supplemented with 0.5 mg L-1 naphthalene acetic acid and various levels (0.5, 1, 1.5, 2, and 2.5 mg L-1) of benzyl adenine. The previously mentioned indices were monitored after eight weeks of culturing. The results showed that 1 mg L-1 benzyl adenine treatment resulted in a significant increase in the percentage of response to shoot multiplication which reached 83.33% after eight weeks of culture. However, apical buds did not respond to shoot multiplication under any of the tested concentrations. Additionally, the axillary buds growing on the MS medium with a concentration of 1.0 mg L-1 benzyl adenine recorded an increase in shoots number and length compared to other treatments with 5.33 shoots per explant and 5.67 cm, respectively. While 0.5 mg L-1 benzyl adenine recorded the lowest shoot multiplication response, shoots length, and number of leaves per shoot (61.0%, 2.33 cm, and 1.67 leaves per shoot, respectively).
