In maize ( Zea mays L. ), the largest staple crop in the world, nitrogen (N) represents a major limiting factor for productivity. However, improving N use efficiency (NUE) is still one of the most critical research issues to achieve food security in a context affected by climate…
As aguardentes vínicas envelhecidas são tradicionalmente percepcionadas como produtos de status e elevada qualidade que, em Portugal, têm uma longa tradição. Tratando-se de um sector que tem verificado, a nível mundial, um aumento de volume e valor das vendas nos últimos anos, p…
Afghanistan is a country with a population of more than 31 million people and is located in south central Asia. The total arable land in the country is 12%, 5% is irrigated and the remaining 7% is rainfed. Due to the lack of available soil information, poor farming practices and…
The increasing energy demand and focus on energy independence of most countries in the world has motivated scientists to find alternative renewable energy sources to fossil fuel. In this connection, biofuel from biomass has been identified to have several benefits including grea…
Cercospora leaf spot (CLS), caused by Cercospora beticola Sacc., is the most destructive foliar disease of sugar beet (Beta vulgaris L.) and various strategies are used for disease management such as the application of fungicides. Fungicide resistance has been reported in C. bet…
Alfalfa (Medicago sativa L.)/perennial bunchgrass hay is grown on marginal soils in the Central High Plains. This region has recently been experiencing frequent droughts. Information on the effects of variation in precipitation on soil nitrogen (N) cycling, greenhouse gas (GHG) …
Legumes associate with soil-dwelling nitrogen fixing rhizobia bacteria, and through this relationship can maintain and increase soil fertility while improving human nutrition, an important function in low-resourced nations such as Malawi. Increasing legume production requires th…
High altitude farmers around the world have a limited set of crops that are adapted to the short growing season and cold temperatures prevalent at high altitudes. Despite the suitability of oilseed crops for high altitude agriculture, little research has been published on the ad…
Leaf sampling and critical value analysis is widely used as a sole method for making nutrient management decisions in pistachio orchards in California. However, the use of leaf sampling as a nutrient management tool has limitations and when used as a sole management tool has the…
Phytophthora root rot and Phytophthora foliar blight are limiting factors in chile production and genetic resistance therefore Phytophthora resistance would be greatly beneficial to producers. Currently, the availability of resistant cultivars is limited. A reason for this limit…
Persistence and longevity of stands of birdsfoot trefoil (Lotus corniculatus L.) are reduced by crown- and root rots. Introduction of L. corniculatus with rhizomes from Morocco is considered an important step towards improving persistence of cultivated birdsfoot trefoil. Rhizome…
Lack of organic input is a major factor contributing to the deterioration of the sandy Alfisols and Entisols in the Sahelian zone of West Africa. Cowpea (Vigna unguiculata (L.) Walp.) has great potential as green manure due to its rapid N accumulation and efficient N\sb2 fixatio…
