| Abstract | ||||
| EFFECTS of NP fertilizer levels on growth and biochemical content of sorghum fodder grown in calcareous soil was investigated in two successive seasons from 2010 to 2011. This study was carried out at Maryout Research Station-Desert Research Center, between longitude 29°47′ and 11°18′ E and latitudes 31°00′ and 15°18′ N. Levels of NP Fertilizer applications were 0, 80, 100, 120 kg N/fed and 0, 20, 30 and 40 kg P2O5/fed. Nitrogen was given as three split applications, whereas P was mixed with organic manure and supplied as a single application. The control treatment was the existing nutrient application of just of manure and potassium, given as a single application. However, organic fertilizer was added to all treatments at rate 10 m3 and also potassium at rate 50 Kg KO5/fed. The results indicated that the application of the larger amounts of N and P had a significant effect (P<0.01) plant higher, the number of leaves, stem diameter, fodder and dry matter yields. In addition, this treatment increased the mineral content of soil and plant with a reduced of hydrocyanic acid (HCN) for fodder sorghum. | ||||
