| Abstract | ||
| This study was carried out during 2015 and 2016 seasons at a private Farm in Road Village in Sahl El-Husseiniya, Sharkia Governorate to study the influence of foliar spraying with three potassium sources at three concentrations from each of them i.e. potassium sulfate1,2 and 4 g/ L; potassium silicate at 1,2,and 4cm/L as well as potassium humate at 1,2 and 4 cm / L beside without foliar spraying (control) to reduce the bad effects salinity stress on growth, yield and quality of pea Master B cultivar under saline soil conditions. The experiment was carried out by using completely randomized blocks design with three replications. Spraying pea plants with potassium silicate (4 cm/L) significantly increased and created the maximum means of all studied traits (growth, yield and yield attributes and chemical constituents in the leaves and seeds) as compared to other studied treatment in the two seasons. Spraying with potassium silicate (2 cm/L) was the second best treatment, followed by potassium silicate at the rate of 1 cm/L, then potassium humate at the rate of 4 cm/L and 2 cm/L in the two seasons. Conversely, the lowest means of these traits resulted from control treatment in the two seasons. Overall, using potassium silicate at different rates as foliar application exceeded using potassium humate at different rates exceeded potassium sulfate at different rates in the two seasons. Concerning proline % in leaves, it had adverse trend comparing with other studied traits in the two seasons. Generally, it could be recommended that spraying pea plants through 4 cm potassium silicate/L to enhance growth, yield and yield components and chemical constituents of pea under the environmental conditions of same research. | ||
