Genetic Variation in Biomass Yield and Feedstock Composition and Trait Relationships in Lowland Switchgrass

Eifion Hughes, Hem Bhandari, Fred Allen, Virginia Sykes, Arnold Saxton, Dennis West and Mathew Bobbitt

Abstract

Switchgrass, a leading candidate for lignocellulosic bioenergy feedstock development in the USA, has received widespread researchers' attention in the recent years. For switchgrass to be an economical alternative to fossil fuels, significant biological and technological advancements have to be accomplished primarily in genetic improvement of biomass and ethanol yields.

Effect of Polythene Mulch on Growth and Yield of Sunflower (Helianthus annuus)

Tapan Kumar, Mohammad Asadul Haque, Md Saiful Islam, Md Fazlul Hoque and Rajib Jodder

Abstract

The study was undertaken to evaluate the effect of polythene mulch and different levels of irrigation water on growth and yield of sunflower in saline soil of Bangladesh. The sunflower variety Pacific Hysun-33 was the test crop. There were eight treatments consisting two continuous irrigation treatments in crop lines once at 25 DAS, and twice at 25 and 50 DAS and six rhizospheric irrigations at a rate of 125, 250 and 500 ml/plant without polythene mulch and with using polythene mulch.

Selection of Potential Plants for Saponin Extract Using Supercritical-CO2 Extraction against Golden Apple Snails (Pomacea canaliculata) for Paddy Cultivation

Ramli NH, Yusup S, Johari K and Abd Rahim M

Abstract

Golden apple snail, (Pomacea canaliculata) has become a major constraint to the profitability of rice (Oryza sativa L.) farming by damaging rice seedlings during paddy growth. Chemical compounds such as saponin, alkaloid and flavanoid have been found in pickerel weed (Monochoria vaginalis), tea leaves, neem and their usage caused the mortality of Pomacea canaliculata.

Socially Modified Organisms in Multifunctional Agriculture - Addressing the Needs of Smallholder Farmers in Africa

Roger RB Leakey

Abstract

To address on-going issues of hunger, malnutrition, poverty and land degradation in Africa, smallholder farmers are developing Socially Modified Crops as part of a 3-step approach to a multifunctional farming system that impact positively on the social, economic and environmental constraints to farm productivity responsible for the gap between potential and actual yield.

Agro-Ecological Zoning for Tall Wheatgrass (Thinopyrum Ponticum) as a Potential Energy and Forage Crop in Salt-Affected and Dry Lands of Argentina

Silvia L Falasca, Carolina Miranda and Sandra Pitta Alvarez

Abstract

Tall wheatgrass (Thinopyrum ponticum previously Agropyron elongatum) is the most disseminated halophyte species cultivated for forage on hydro-halomorphic soils in the world. In Argentina, it is used for direct pasturing, hay and silage. The traditional cultivation area comprises poorly drained soils of the Pampean prairie, particularly the Salado river basin and the Semiarid Pampean Region.

Investigation of Biological Processes Aimed at Improving the Quality of Compost from Bio-Waste

Francesco Di Maria

Abstract

Exclusively aerobic and integrated anaerobic with post-aerobic treatments of bio-waste generated in a given waste management area were compared with respect to the quality of the final compost. Pilot-scale apparatuses were used for reproducing static aerated pile composting and solid anaerobic digestion batch (SADB) for the anaerobic pre-treatment. Compost was assessed according to the organic carbon content and humic and fulvic acid concentrations.
