Effect of Nitrogen Fertilizer On Some Attributes of Sorghumgrown in Saline Soil Under Irrigation - Effect of Nitrogen Fertilizer On Some Attributes of Sorghumgrown in Saline Soil Under Irrigation - Open Access Pub

The main objective of this study was to investigate the effects of 4 levels of Nitrogen (N) fertilizer (0, 25, 50 and 75 Kg N/fed) on some attributes of Sorghum (Sorghum bicolor L). This study was conducted in the farm of College of Agriculture, University of Bahri-Sudan; during the period 2014-2015. Where the soil is classified as saline with pH ranging from 7.5 -7.8. A randomized completely block designed (RCBD); with 3 replications and four (4) treatments was adopted. All recommended cultural practices were carried out timely. Data; pertaining some plant attributes were collected and analyzed. The result showed that the application of 75KgN/fed has increased both; the average number of leaves as well as the plant height compared to other levels of Nitrogen fertilizer including the control (Figure 1, Figure 2). For the average number of tillers concern, there is non -significant difference between all Nitrogen levels and average number of tillers (Figure 3). The study concluded that the Nitrogen fertilizer has variable effects on the studied agronomic characters, and the application of 75kgN/fed is the optimal level of fertilizer for improving the agronomic traits of Sorghum under Alkadaro conditions. DOI10.14302/issn.2639-3166.jar-18-2239 Sorghum (Sorghum bicolor L. Moench) is an annual self- pollinated crop which belongs to family gramineae (poaecae). It ranks the fifth most important cereal crops in the world. It is grown in the arid, semi-arid, tropical and sub-tropical regions of the world between 40 N and 40 S of equator 1. This crop is sensitive to low temperature, but tolerates high temperature better than any other cereal crops. Therefore; it is called drought tolerant. Nevertheless, it can be produced on wide range of soil (pH) ranging from 5.0 to 8.5 2, but the production is influenced by various factors, among these, the moisture, temperature, soil type, irrigation water, fertilizers, and soil pH 3. Sorghum is stable food for millions of people in Africa and India. It is widely used for human consumption; as well as animal feed. The dry stalks are commonly used as fuel for cooking and fencing or roofing huts4. The Sorghum grain also used in manufacturing starch, alcohol and glucose 5. Sorghum (Sorghum bicolor L.) (Dura in Arabic) is a common source of human food an animal feed in most parts of the world including Africa, Central America, and South Asia6. It is reported that 440,000 kilometers2 were devoted worldwide to Sorghum production in 2004 7. Africa a lone produces about 20 mt of Sorghum per annum, which is equal to one-third of the
