Integrated food and bioenergy production is a promising way to ensure regional/national energy security, efficient use of soil resources, enhanced biodiversity, while contributing the abatement CO2 emissions. The objective this study was assess alternative crop rotation schemes as basis for integrating enhancing sustainable biomass within food-energy agricultural context. Sunn hemp (Crotalaria ...

Cover crops are a major focus of conservation agriculture efforts because they can provide soil cover and increase nutrient availability after their mineralization in cropping systems. To evaluate the effect of residue type and placement on rate of decomposition and carbon (C) and nitrogen (N) mineralization, residues from two food crops, maize (Zea mays L.) and common bean (Phaseolus vulgaris ...

While mixed-species cover crops are gaining worldwide popularity, their utility in the ‘plough-out’ period tropical sugar cane systems has not been investigated. Field trials investigating weed suppression (one season only), biomass production and nitrogen accumulation of single-species were conducted over two seasons on a commercial sugarcane farm Australian tropics. Mixed-species showed stron...

Legumes match the nodule number to the N demand of the plant. When a mutation in the regulatory mechanism deprives the plant of that ability, an excessive number of nodules are formed. These mutants show low productivity in the fields, mainly due to the high carbon burden caused through the necessity to supply numerous nodules. The objective of this study was to clarify whether through optimal ...

eurygaster integriceps Puton, commonly known as sunn pest, is a major pest of wheat in Northern Africa, the Middle East and Eastern Europe. This insect injects a prolyl endoprotease into the wheat, destroying the gluten. The purpose of this study was to clone the full length cDNA of the sunn pest prolyl endoprotease (spPEP) for expression in E. coli and to compare the amino acid sequence of the...

ABSTRACT Sunn hemp (Crotalaria spectabilis) is widely used for soil correction and cover, but it still necessary to know the characteristics that influence storage of its seeds. This study aimed evaluate physiological quality sunn seeds under uncontrolled environmental conditions in acclimatization chamber. A completely randomized experimental design was used, with four replicates, subplots eva...

The CLAVATA3/embryo-surrounding region (CLE) peptides control the fine balance between proliferation and differentiation in plant development. We studied the role of CLE peptides during indeterminate nodule development and identified 25 MtCLE peptide genes in the Medicago truncatula genome, of which two genes, MtCLE12 and MtCLE13, had nodulation-related expression patterns that were linked to p...
