Two field experiments were carried out at the Experimental Research Station, Faculty of Agriculture, Moshtohor, Benha University, Kalubia Governorate, Egypt, during 2013/14 and 2014/15 winter seasons to evaluate the performance of five faba bean genotypes (Moshtohor 5, Moshtohor 8, Moshtohor 1084, Misr 3 and Nobaria 3) under four water regimes which were, single irrigation at flowering stage (90-day after planting (DAP)), two irrigations during vegetative growth and at pods formation stages (60 and 120 DAP, respectively), three irrigations during vegetative growth, flowering and pod formation stages(45, 90 and 135 DAP, respectively) and regular irrigations. The results could be summarized from the combined analyses as follows: All of the study traits were significantly increased in their magnitudes by the increase in number of irrigations except for the number of pods and seeds plant-1. The differences between faba bean genotypes were significant for all the studied traits. Moshtohor 1084 genotype was of the highest values of number of seeds, weight of pods and seeds plant-1, 100-seed weight, biological and seed yields fed-1 and protein yield fed-1; while Nobaria 3 variety gave the highest values for number of pods plant-1 and crude protein percentage of seeds. Significant interaction effect was noticed between the applied irrigation regimes and broad bean genotypes for all of the studied characters. The highest number of pods plant-1, number of seeds plant-1, weight of pods and seeds plant-1, biological and seed yields fed-1 and crude protein yield fed-1 were recorded for Moshtohor 1084 genotype when normal irrigation was applied. Whereas, the heaviest weight of 100-seed was recorded for Nobaria 3 variety under normal irrigation. The simple correlation study indicated positive significant and correlation coefficients between seed yield fed-1 and each of other studied traits.
In general, either faba bean Moshtohor 1084 genotype or Nobaria 3 variety irrigated normally or with the three irrigations treatment looks to be recommended for Moshtohor environmental and edaphic conditions. |
