Book Description
Sunflower is the second most important oil seed crop in the world. Nitrogen is the most of important nutrient for crop production and is required throughout the crop growth period from vegetative stage to subsequent harvesting. One of the main causes of low yield is imbalanced and inadequate supply of nutrients. Proper amount and time of fertilizer application is considered a key to the bumper crop. The most logical approach to increasing N fertilizer use efficiency is to supply nitrogen when it is needed by the crop. Use of optimum amount of fertilizer through a suitable application method at a time when it is most efficiently and effectively utilized is imperative. Plant N use efficiency can be improved by matching application rate and timing with plant demands. This study was proposed to investigate the effect of timing and nitrogen fertilizer application on growth and yield of sunflower.

Book Description
Nitrogen in the Environment: Sources, Problems, and Management is the first volume to provide a holistic perspective and comprehensive treatment of nitrogen from field, to ecosystem, to treatment of urban and rural drinking water supplies, while also including a historical overview, human health impacts and policy considerations. It provides a worldwide perspective on nitrogen and agriculture. Nitrogen is one of the most critical elements required in agricultural systems for the production of crops for feed, food and fiber. The ever-increasing world population requires increasing use of nitrogen in agriculture to supply human needs for dietary protein. Worldwide demand for nitrogen will increase as a direct response to increasing population. Strategies and perspectives are considered to improve nitrogen-use efficiency. Issues of nitrogen in crop and human nutrition, and transport and transformations along the continuum from farm field to ground water, watersheds, streams, rivers, and coastal marine environments are discussed. Described are aerial transport of nitrogen from livestock and agricultural systems and the potential for deposition and impacts. The current status of nitrogen in the environment in selected terrestrial and coastal environments and crop and forest ecosystems and development of emerging technologies to minimize nitrogen impacts on the environment are addressed. The nitrogen cycle provides a framework for assessing broad scale or even global strategies to improve nitrogen use efficiency. Growing human populations are the driving force that requires increased nitrogen inputs. These increasing inputs into the food-production system directly result in increased livestock and human-excretory nitrogen contribution into the environment. The scope of this book is diverse, covering a range of topics and issues from furthering our understanding of nitrogen in the environment to policy considerations at both farm and national scales.
