Effect of transplanted seedling age of intercropped fodder beet with faba bean and nitrogen fertilizer levels on, yield and it's component of fodder beet and faba bean [electronic resource].

Two field trails were conducted at El-Gemmeiza Research Station, Gharbia Governolevel during 2009/2010 and 2010/2011winter seasons to investigate the effect of transplanting fodder beet seedling at different ages 18(P₁), 32 (P₂) and 46 (P₃) days from planting and three nitrogen fertilizer levels 90 (A₁), 100 (A₂) and 110 (A₃) kg N/fad on growth, yield and yield components of intercropped fodder beet and faba bean. The results could be summarized as follows: Faba bean growth yield and yield components were reduced under intercropping. Seeds yield/fad. of faba bean was significantly reduced by intercropping with fodder beet, compared to faba bean pure stand. The reductions were 34.0 and 48.17% for P₁, 26.7 and 41.63% for P₂ as well as 21.46 and 32.8% for P₃ in the first and second seasons, respectively. There were significant effect of nitrogen fertilizer levels on faba bean growth, yield and it's components. The highest values of the traits were recorded by nitrogen level 90 kg N/fad., (A₁).Root yield and it's component of fodder beet were significantly decreased in the three transplanting ages as compared with direct seeded in both seasons. The highest reduction was observed by the third transplanting age and the lowest with the first age. These reductions estimated in the third age were 25.15 and 22.75% for top fresh weight/plant, 16.24 and 12.42% for root length, 11.75 and 20.27% for root diameter, 16.30 and 27.16% for root yield/fad., in the first and second seasons, respectively.
