Heterosis in switchgrass: Biomass yield in swards
Improving the biomass yield of switchgrass (Panicum virgatum L.) will improve its utility as a dedicated energy crop by increasing both its net and total energy yield per hectare. In a previous space-transplanted study, midparent heterosis for biomass yield was reported for population and specific F1 hybrids of the lowland-tetraploid cultivar Kanlow and the upland-tetraploid cultivar Summer. ...

Focus Bioenergy No 4 2004: Energy crops - a resource for development
Agricultural fuels like energy forest, straw fuels, ley crops, oil crops and grain can be used for heat, electricity or transports and may become an important complement to forest fuels in replacing the fossil fuels. Cultivation of Salix is already commercially viable in Sweden. The future for agricultural fuels depends on many factors: how the EU’s common agricultural policy will develop, how ...

Potential of crop residue in India as a source of energy
Here is given an estimate of crop residue production and different recycling options as a source of renewable energy. India produces 388 Tg crop residues but only 182 Tg equivalent to 2818 PJ is usable. Recycling as manure can replace 15% of 595 PJ national fertiliser energy. Recycling in digester can produce 20.32 billion m? biogas. It can be converted into 182 Tg of biocoal generating 156?258.3 ...

The Effect of Wastewater Irrigation on Perennial Energy Crops
Using treated wastewater to irrigate energy crops is a favourable alternative for traditional irrigation, especially on marginal lands or in seasons when water is scarce. Although irrigating crops with reused wastewater (even when used to irrigate non-food crop) not always have social acceptance, considering the amount of wastewater daily available, and its high nutrient loads, it is a ...

Estimation of possible energy contributions of crop residues in Nigeria
This study applied a simple methodology to evaluate energy contribution of selected crop residues to the possible replacement of conventional sources of energy and their specific technologies based on Nigerian situations. Using this methodology, energy content, replacement energy value, energy cost and energy return of crop residue (kJ per kg dry matter) were considered. The cost estimates of ...

Nitrogen influences biomass and nutrient partitioning by perennial, warm-season grasses
Recent attention has focused on the use of perennial, warm-season grasses as renewable energy crops. The objective of this study was to assess the effects of N fertilization on partitioning of biomass and nutrients between above- and belowground plant components by four warm-season grass species in Iowa. In 2006–2007, established stands of big bluestem (Andropogon geradii Vitman), switchgrass ...

Energy for 2,150 households: our flagship project in Icknield (UK) - Case Study
Location:Ipsden, Oxfordshire (UK) Capacity:700 Nm³/h biomethane + 360 kWel CHP Input materials:Pig slurry, farm by-products, energy crops Special Features:The plant is capable of supplying enough gas to meet the annual needs of around 2,150 households. The subsequent reuse of the digestate as fertiliser also helps to reduce the use of chemical fertilisers by local agricultural ...

Reuse of constructed wetland effluents for irrigation of energy crops
The aim of this study was to evaluate biomass production of promising ‘no-food’ energy crops, Vetiveria zizanoides (L.) Nash, Miscanthus × giganteus Greef et Deu. and Arundo donax (L.), irrigated with low quality water at different evapotranspiration restitutions. Two horizontal subsurface flow (H-SSF) constructed wetland (CW) beds, with different operation life (12 and 6 ...

A decision tool for sustainable agricultural policies: the case of water saving scenarios for Apulia Region (Southern Italy)
The economy of Apulia Region largely depends on agriculture but the scarce water resources are the main factor threatening the sustainable production of this sector. This paper describes a geographical information system (GIS) based water balance tool that integrates maps of crops, climate and soil parameters with various scenarios of cropping pattern and farming practice changes. The aim is ...

How to Help Grapevines Recover after a Difficult Frost Period
100% : this is the percentage of a vineyard that can be damaged by frost Cold snaps and frosts have hit many orchards and vineyards these last few weeks in France. High yield reduction will be expected due to these cold waves, occurring after weeks of heat and crop development. During dormancy, grapevines can support temperatures as low as -15°C. However, as soon as the vines bud, they ...

Biomass Production of Arundo Donax: A Country Specific Overview
With around 50-80 dry tonnes of biomass yield per hectare every year, Arundo donax (giant reed) is way ahead of its competitors. Of course, this yield depends on climate and applied agricultural technology. In this article below, the studies carried out concerning the biomass yield and economics of Arundo donax are presented. Biomass production in the Mediterranean: Italy, Spain and Sicily ...

The water footprint of sweeteners and bio-ethanol
An increasing demand for food together with a growing demand for energy crops result in an increasing demand for and competition over water. Sugar cane, sugar beet and maize are not only essential food crops, but also important feedstock for bio-ethanol. Crop growth requires water, a scarce resource. This study aims to assess the green, blue and grey water footprint (WF) of sweeteners and ...

Influence of nitrogen fertilizer on Cd and Zn accumulation in rapeseed (Brassica napus L.) biomass
Diffuse soil contamination with heavy metals and Cd in particular is a matter of serious concern. Application of conventional remediation methods usually is not feasible due to the large territories and relatively low heavy metal content. Thus, phytoremediation is seen as an alternative. Rapeseed was grown on Cd and Zn contaminated as well as clean soil under the greenhouse conditions. Solid and ...

What is the Market Prospect of Sweet Potato Deep Processing?
Sweet potato is one of the world's major food crops and one of the four major crops in China. China is still in its infancy in the research and comprehensive development of the sweet potato utilization project. Most of the sweet potato products stay in the rough processing of sweet potato, sweet potato vermicelli and sweet potato starch. The value that sweet potato is not well known to most ...

The water we eat
Agriculture imposes a heavy and growing burden on Europe's water resources, threatening water shortages and damage to ecosystems. To achieve sustainable water use, farmers must be given the right price incentives, advice and assistance. Food is intrinsically bound to human wellbeing. Besides the importance of good food for good health and the pleasure we derive from eating, agricultural ...

Can pulse crops play a role in mitigating greenhouse gases from North American agriculture?
The atmospheric buildup of greenhouse gases (GHGs) is a serious environmental issue. Globally, agricultural activities are an important source of anthropogenic GHGs, contributing 20% of the annual atmospheric increase. Management choices largely determine if agricultural soils will be a source, a sink, or will be neutral with respect to GHG net flux. The proportion of agricultural land that is ...
