Abstract
To investigate the impact of some stimulants on the pea plants grown under high-temperature conditions, a field experiment was conducted to assess the effects of vitamin C, melatonin, potassium citrate, and cytokinin, in addition to a control group that did not receive any spray, on pea cultivars including A (master b), B (sweet 1), and C (sweet 2), which were assigned to the main plots. While, the stimulants were arranged in the sub-main plots. The experiment measured various growth and yield parameters, including plant height, leaf area, fresh and dry weights, chlorophyll content, carotene content, days required for fruit setting, No. of pods, pod length, pod yield and protein content. The results showed that the cultivar "C" performed the best across all studied treatments, except for days required for fruit setting. Following "C" cultivar, the performance of cultivar "B" was observed to be superior, while cultivar "A" ranked third in terms of growth and yield characteristics. In terms of fruit setting, cultivars "A" and "B" exhibited early fruit setting, whereas cultivar "C" experienced a delay in fruit set. Regarding the stimulants, spraying cytokinin yielded the highest values for all the studied characteristics. Potassium citrate treatment ranked second in terms of performance, followed by melatonin then vitamin C treatments, respectively, while the control group showed the lowest values. Overall, the application of cytokinin had the most positive impact on the growth and yield of pea plants under high-temperature conditions. Other studied stimulants also had positive effects, although to a lesser extent.
