Abstract | ||||
Two field experiments were carried out at the Experimental Farm, Faculty of Agriculture, Menoufia University, Shebin El-Kom, Egypt to investigate the effect of plant densities (80000, 120000 and 160000 plants/fed), phosphorus fertilization systems (7.5 kg P2O5/fed as soil application + twice foliar application with 0.5% phosphoric acid, 15 kg P2O5/fed as soil application + once foliar application with 0.5% phosphoric acid and 22.5 kg P2O5/fed as soil application) on growth and productivity of some faba bean cultivars (Sakha 1, Sakha 3, Sakha 4, Giza 3, Giza 402, Giza 461, Giza 716, Giza 843, Nubaria 1 and Misr 1) during 2012/2013 and 2013/2014 seasons. The results obtained could be summarized as follows: 1- The lowest plant density (80000 plants/fed) surpassed the other densities in most growth characters, crop growth rate, number of flowers/plant, total chlorophyll, water relations%, seed yield/ plant and its components and seed chemical analysis. However, increasing plant density up to 160000 plants/fed increased seed, straw and biological yields/fed. 2- Giza 3 and Sakha 4 cultivars surpassed the other cultivars in most characters studied. 3- Fertilization system with 15.0 kg P2O5/fed as soil application + once foliar application with 0.5% phosphoric acid surpassed the other systems for produced the highest values of most characters studied. 4- From the interaction data, it could be concluded that planting Giza 3 cultivar at the highest density (160000 plants/fed) as well as fertilized with 15 kg P2O5/fed as soil application + once foliar application with 0.5% phosphoric acid being the most effective combined treatments for maximizing seed yield/fed under the experiment conditions. | ||||
