Abstract: A pot experiment was conducted at the greenhouse of NRC, DOkki, Giza, Egypt, using clay loam soil to study the effect of different moisture regimes (M1. M2 and M3) and fertilizer treatment (F0, F1, F2, F3 and F4) on growth parameters and yield of rice plants ( variety Sakha 102 and Giza 0176). The important results could be summarized in the follows: Growth parameters (plant height and number of tillers per plant) and yield of rice plants were highly significantly increased by using soil moisture regime of (M1) followed by M2 and M3 in decreasing order of the tow rice varieties (Giza 176 and Sakha 102). - Results indicated that all the used fertilizer treatments i. e. inorganic fertilizer (F1 and F2), organic fertilizer (F4) and their combination (F3) significantly increased the growth parameters, straw and Grain yields of both rice varieties compared with those obtained under non fertilizer treatment (F0). - Inorganic fertilizers (F1 and F2) treatment significantly increased the growth parameters and yield of rice as compared with those obtained by using the organic fertilizer treatment (F4). - The highest values of the growth parameters and yield were obtained by using the fertilizer treatment of F3 (organic and inorganic in combination) followed by the two rates of inorganic fertilizer treatments (F2 and F1) and F4 (organic fertilizer alone) in descending order. - The interaction between soil moisture regimes and fertilizer treatments significantly affected all that studies the growth and yield of two varieties. The highest values of the growth parameters, straw and grain yields of rice plants were obtained under soil moisture regime of M1 and using fertilizer treatment of F3 (M1 F3), while the lowest values were obtained under soil moisture rgimes of M3 and without fertilizers (M3). - Results show that shakha 102 out yielded Giza 176 variety in straw and grains yields.
