A HEDONIC MODEL OF RICE TRAITS: ECONOMIC VALUES FROM FARMERS IN WEST AFRICA
Provedor de dados: 31
Autores: Dalton,   Timothy J.
New crop varieties often have been promoted in developing countries based upon superior yield vis-a-vis locally available varieties.  This research presents a hedonic model for upland rice by drawing upon the input characteristics and consumer good characteristics model literature.  Model specification tests determine that a combination of production and consumption characteristics best explains the willingness to pay for new upland rice varieties.  This non-separable household model specification determined that four traits explain the willingness to pay for new rice varieties: plant cycle length, plant height, grain elongation/swelling and tenderness.  Yield was not significant explanatory variable for the willingness to pay for seed.  The implications...

Changed the way of the upland rice field into the rice terraces is the choice of how to grow upland rice, strengthen and support the community food security (rice). It can reduce the shortage of rice that is not enough for consumption. It can reduce aggression and sustainable forest conservation area. In Phitsanulok province (lower northern part), this project has operated since the year 2010, resulting alternative way to the rice field terraces. In these areas, Chat Trakan and Nakhon Thai districts, Phitsanulok, 41.6 rais of the slope field were adjusted to the rice terraces, up to 707.1 rais from the present (2012) and expected trend in the year 2013 will be increase to 2,000 rais.

Measurement of methane emission from rice production systems is a methodology for data collection of Carbon Footprint from rice production system. Four major rice production systems were defined for methane emission measurement in 2012, including upland rice, rainfed rice, irrigated rice with good agricultural practices (GAP) and irrigated rice with alternative wet and dry (AWD). Gas samples were taken one week interval and analyzed by Gas Chromatograph; GC-8A as soon as possible after collection. The research found that upland rice could absorb CH4 at the rate of 0.176 kg methane rai-1 season-1. Rainfed rice production system in Northeast Thailand emitted CH4 at the rate of 85.26 kg rai-1 season-1 under transplanting and 51.64 kg rai-1 season-1 under...

Crossing rate and distance in upland rice
Provedor de dados: 53
Autores: Silva,Edson Ferreira da; Silva,Lucielio Manoel da; Montalván,Ricardo.
Rice (Oryza sativa L.) is an autogamous species that shows natural crossing rates of up to 3%, where the variations are influenced by genotypes and environments. The present work aimed to evaluate the rates and distances of natural crossing between the upland rice cultivars Guarani and IAC 201. The study was done in the counties of Carpina and Recife, in the State of Pernambuco during the agricultural years of 2001 and 2002, respectively. The Guarani cultivar presents leaf pilosity conditioned by the dominant alleles HLHL and this character was used as a morphologic tracer. On the other hand, the IAC 201 cultivar does not show pilosity because it carries the recessive alleles (hlhl). The experiments were composed of four blocks, constituting of ten...

Crop models are ideally suited to quantify existing climatic risks. However, they require historic climate data as input. While daily temperature and rainfall data are often available, the lack of observed solar radiation (Rs) data severely limits site-specific crop modelling. The objective of this study was to estimate Rs based on air temperature solar radiation models and to quantify the propagation of errors in simulated radiation on several APSIM/ORYZA crop model seasonal outputs, yield, biomass, leaf area (LAI) and total accumulated solar radiation (SRA) during the crop cycle. The accuracy of the 5 models for estimated daily solar radiation was similar, and it was not substantially different among sites. For water limited environments (no irrigation),...
