A Network behind Coffee

Authors: Liliana Bravo-Monroy

Abstract: Small-scale family farmers throughout the world have long struggled with the dilemmas of disparity between international coffee prices and producers profits. Drawing on a case study conducted on perceptions of coffee productivity in a coffee-producing area of Colombia in 2010-11 (Ocamonte, Santander area), I examine the role of human and non-human actors in completing the journey of coffee from crop to cup. This article explores key actors involved in coffee production systems, social circuits and markets, highlighting the importance of connections between growers acting at local scales and people who are distant at international scales e.g., intermediaries, processors, traders

A Conceptual Tool for Sustainable Management of Rice Residue: Using Rice Straw-Based Formulations as Elicitors of Induced Resistance against Plant Pathogens

Authors: Soum Sanogo

Abstract: The general focus of this letter is on the issue of rice straw management. The letter succinctly describes the challenges faced in the management of rice straw. Then, the letter makes a case for an innovative approach to managing rice straw by using rice straw for disease and pest control. Within this context, the letter pinpoints the biochemical characteristics of rice straw and the potential of exploiting these characteristics by using rice straw as a source of exogenous phenolic acids for eliciting induced resistance. This perspective is unique, and to the knowledge of the author, it has not been considered previously in the literature of rice straw management.

Methane Production as Affected by Tillage Practice and NBPT Rate from a Silt-Loam Soil in Arkansas

Authors: Joshua Humphreys, Kristofor R Brye, Casey Rector, Edward E Gbur and Nathan A Slaton

Abstract: Greenhouse gas (GHG) emissions from agricultural settings have come under great scrutiny in the past 20 years and the impact of GHGs in the environment regarding global climate change is alarming. Understanding the conditions and mechanisms that produce GHGs, specifically methane (CH4), are needed to better attenuate the release of CH4 from various agronomic practices in agricultural settings, particularly from rice (Oryza sativa L.) production. The objective of the study was to evaluate the effects of tillage [conventional tillage (CT) and no-tillage (NT)] and urea fertilization.

Comparative Evaluation of Rice SSR Markers on Different Oryza Species

Authors: Getachew Melaku, Shilai Zhang and Teklehaymanot Haileselassie

Abstract: The growing number of rice microsatellite markers permit a comprehensive comparison of allelic variation among the markers developed using different methods, with diverse repeat motifs and at variable genomic regions. Under this study, comparison between a set of 67 microsatellite markers representing the whole (twelve) rice chromosomes was done over worldwide collections of nine species of the genus Oryza. These SSR markers were evaluated for the genetic parameters such as; number of alleles amplified per primers, observed heterozygosity, gene diversity, rare allelic frequency and Polymorphic Information Content (PIC) values.

Tillage and Coated-Urea Effects on Nitrous Oxide Emissions from Direct-Seeded, Delayed-Flood Rice Production in Arkansas

Authors: Casey Rector, Kristofor R Brye, Joshua Humphreys, Richard J Norman, Nathan A Slaton, Edward E Gbur, Cammy Willett and Michelle A Evans-White

Abstract: Rice (Oryza sativa L.) is a key component of the diet of billions of humans, thus rice is a main agricultural product in many regions, particularly in eastern Arkansas, USA. Rice production is known to be a source of greenhouse gases, namely methane (CH4), but, under certain conditions, nitrous oxide (N2O) as well. The objective of this study was to evaluate the effects of tillage practice [conventional tillage (CT) and no-tillage (NT)] and urea fertilizer type [N-(n-butyl) thiophosphoric triamide (NBPT)-coated and non-coated urea] on N2O fluxes, season-long N2O emissions, and the global warming potential (GWP) from rice grown in eastern Arkansas in a direct-seeded, delayed-flood production system on a silt-loam soil.

Water Management and Cultivar Effects on Methane Emissions from Direct-seeded, Delayed-flood Rice Production in Arkansas

Authors: Joshua Humphreys, Kristofor R Brye, Casey Rector, Edward E Gbur and Jarrod T Hardke

Abstract: Methane (CH4) emissions from rice (Oryza sativa L.) production are a source of concern in the environmental and agricultural communities. New and/or revised agronomic methodologies will be needed to identify production practice combinations that reduced CH4 emissions without decreasing yields or milling quality.

Approaches to the Study of Plant-Phytopathogen Interactions: In Vivo and In Vitro Assay Systems of Phytobacterial Pathogenesis

Authors: Seunghwan KIM, Jeong-Gu KIM, and Lin-Woo KANG

Abstract: Plant-phytopathogen interactions, such as rice-Xanthomonas oryzae pv. oryzae (Xoo) interactions, are important for the fate of both the host plant and invading phytopathogen, particularly in the early stage of infection.

Is Phenotypic Variability in Leaf Vein Density in Rice Associated with Grain Yield?

Authors: Ruwanthi Nayananjalee Nawarathna, Kithsiri Bandara Dassanayake, Sarath Premalal Nissanka, Saman Seneweera and Phillip Salisbury

Abstract: Rice, Oryza sativa L. is the staple food of half of the world's population, mostly in Asia. Therefore, it is essential to increase rice yield to meet the rising food demand by the year 2050.
