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 cereal crops: Is breeding for reduced grain phosphorus concentration part of the solution?
Given the non-renewable nature of global phosphate reserves, there is a push to increase the phosphorus (P) efficiency of agricultural crops. Research has typically focussed on investigating P acquisition efficiency or internal P utilization efficiency to reduce crop fertilizer requirements. A novel option that would reduce the amount of P exported from fields at harvest, and may ultimately red...
متن کاملPhosphorus in Agriculture: Need for Efficient Use and Re-Use
Phosphorus (P) is the 11th most abundant element of the earth’s crust. Phosphorus (P) is an essential element for all living organisms. The world’s main source of P is phosphate (Pi) rock. It is a non-renewable resource. There is neither any alternative to P nor a synthetic way of creating it. P is involved in various basic biological functions, for instance as a structural element in nucleic a...
متن کاملOpportunities For Improving Reproductive Management And Efficiency Of The Swine Breeding Herd With Artificial Insemination
Current Status of AI Use The USA swine breeding herd has been reported to include 3.9 million sows. Approximately 60% of these sows were determined to have been mated by artificial insemination. Each sow received 6.5 doses of semen annually, for a total of 25 million doses utilized in a single year (1999, Boar Semen Conference). Most of the AI is performed with 3 billion sperm in 80 cc of a 5-d...
متن کاملBreeding for high water-use efficiency.
There is a pressing need to improve the water-use efficiency of rain-fed and irrigated crop production. Breeding crop varieties with higher water-use efficiency is seen as providing part of the solution. Three key processes can be exploited in breeding for high water-use efficiency: (i) moving more of the available water through the crop rather than it being wasted as evaporation from the soil ...
