Improving Nitrogen Use Efficiency in Crops for Sustainable Agriculture
In this review, we present the recent developments and future prospects of improving nitrogen use efficiency (NUE) in crops using various complementary approaches. These include conventional breeding and molecular genetics, in addition to alternative farming techniques based on no-till continuous cover cropping cultures and/or organic nitrogen (N) nutrition. Whatever the mode of N fertilization...
متن کاملImproving Phosphorus Efficiency in Crops with Focus on Purple Acid Phosphatase: Potentials and Perspective
Low-phosphorus (P) stress as a key factor limiting plant growth and production is common in most agricultural soils. Most of the soil-applied phosphate will be rapidly immobilized and most of annually applied phosphate fertilizers are fixed in the soil in organic forms by adsorption, sedimentation and transformation. However, excess P application may lead to contamination of water sources by en...
متن کاملBiotechnology Approaches to Improving Maize Nitrogen Use Efficiency
Nitrogen (N) is an essential and often limiting nutrient to plant growth. Maize grain yields are highly responsive to supplemental N, leading to annual application of an estimated 10 million metric tons of N fertilizer to the maize crop worldwide (FAO 2004). Nearly all cultivated maize in developed countries receives some form of N fertilizer and N use is increasing in developing countries, whe...
متن کاملGenetic Engineering Approaches to Improving Nitrogen Use Efficiency
Since nitrogen (N) is the most essential nutrient for plants and a major limiting factor in plant productivity, doubling agricultural food production worldwide over the past four decades is associated with a 20-fold increase in N fertilizer use. As a consequence, use of N fertilizers in agriculture has already shown a number of detrimental environmental impacts. Therefore, the need to reduce N ...
متن کاملchallenges and approaches for enhancing of water use efficiency in field crops in iran
crop’s water use efficiency (wue) is one of the major indices for the efficient use of water for crop production in agriculture. based on scientific literatures, the concept of wue has been defined in all crop management, farm/field, and water basin/irrigation network domains. plant in particular, plays an important role in the efficient use of water and enhancement of wue. plant resistance to ...
