Two filed experiment were conducted at El-Baramoon Experimental Farm during 2016/2017 and 2017/2018 seasons to study effect of sowing dates and some growth stimulants on growth, yield and its component and seed quality of pea. The experiment was laid-out in a split-plot design with three replications. Sowing on 1st week of Sept. recorded the best results of plant height, number of leaves, fresh and dry weights of plant, N, P and K contents in leaves, pods number/plant, yield per plant and feddan than. Treated pea plants with NPK at 50 % of RR + humic acid + magnetic iron recorded highest values of plant height, number of leaves, total fresh and dry weights/plant, yield per plant fed in the both seasons and 100-seed weight in 2nd season. The N, P and K % in leaves were obtained with NPK at 50 % RR + humic acid + proline. Sowing on 1st week of Sept. and fertilizing with NPK at 50 % RR + humic acid + magnetic iron increased plant height, number of leaves, total fresh and dry weights/plant, yield per plant fed in both seasons and 100 seed weight in the 2nd season. While, sowing on 1st week of Feb. and spraying with proline amino increased proline content and oxides enzyme activity. Meanwhile, sowing on 1st week of Sept. and fertilizing with NPK at 50 % RR+ humic acid + proline gave the highest values of N, K and lowest values of proline content and oxides enzyme.
