| Abstract | ||||
| The present study aimed to investigate the variation rates between sowing dates, seed sizes and seed priming treatments as well as their interactions on seed vigor, field emergence, yield and it`s components of faba bean. In the laboratory experiment, treatments were arranged in a completely randomized design with three replicates for each experiment of germination temperature (15°C, 22°C and 30°C) included two factors, the first assigned as seed size categories (larger size ≥110g, medium size 70-75g and smaller size ≤45g). The second factor occupied with seed priming treatments (unprimed seed, 100 ppm GA3 and 200 ppm GA3). Results revealed that, temperature (22°C), larger size (≥110g) and GA3 (200 ppm) recorded the highest significant rates of seed vigor indices, while the lowest values were obtained by 30°C, smaller size (≤45g) and the unprimed seed. Regarding field experiment, it was laid in a split plot design with three replicates for each sowing date (1st October, 1st November and 1st December), included seed sizes in the main plots and the seed priming treatments in the subplots, during 2016/2017 and 2017/2018 seasons. Results indicated that; the 1st November, larger size (≥110g) and GA3 (200 ppm) presented the highest values of field emergence, plant height, No. pods and seed yield plant-1, 100 seed weight and seed yield fed-1 during the two growing seasons. More, the triple interaction showed significant variance (P≤0.05) rates on plant height (2ndseason), No. pods plant-1 (1st season), seed yield plant-1 (1stseason) and 100 seed weight (1stseason) and seed yield fed-1 (1stseason). | ||||
