Abstract:

A procedure was developed to estimate optimum irrigation requirements for lowland rice cultivation in Southeast Asia. The procedure uses a water balance equation of semi-stochastic nature to maintain minimum desired water depths in paddy fields at the end of each irrigation period. The procedure estimates weekly pan evaporation (EV) and rainfall (RF) at different probability levels, which is then used to determine weekly irrigation requirements at different probability levels. To illustrate the use of the method, the Kalawewa irrigation scheme in Sri Lanka was selected for demonstration purp

Abstract:

Rice is a staple crop for many countries around the world, and is one of the top three food sources globally. Many environments where rice is grown contain stressors likely to limit its growth and yield. In southern Senegal (Casamance region), rice is mainly cultivated in lowlands near estuaries where drought, salinity, acidity, poor soil fertility, and iron toxicity are the main limiting factors. In Casamance, average rice yield for local farmers is 1 to 2 tons per hectare (809 to 1618 pounds per acre), compared to worldwide average yield of more than 4 tons per hectare.

Abstract:

Water scarcity combined with an increasing world population is creating pressure to develop new methods for producing food using less water. Rice is a staple crop with a very high water demand. This study examined the success in maintaining yields under water-saving irrigation management, including alternate wetting and drying (AWD). A meta-analysis was conducted examining yields under various types of water-saving irrigation compared to control plots kept under continuous flooding. The results indicated that yields can indeed be maintained under AWD as long as the field water level during the

Abstract:

Modern rice (Oryza sativa L.) varieties produce very high yields under high input and favorable environments. Limited work has been done to develop plant types suitable for less than optimal environments at moderate N management levels. The objectives of this study were: 1) to examine the relationship between the uptake of N and different leaf characteristics, sink size, and grain yield of three morphologically distinct rice varieties; 2) to examine the CO2 exchange rates (CER) of rice varieties in relation to light, N management, water use efficiencies (WUE), and N use efficiency (NUE): and 3

Abstract:

An Giang province is one of the largest rice producer regions in Vietnam with 600,000 hectares of paddy field and 4 million tons of rice production every year. The rice milling industry generates a huge amount of rice husk (~23% of paddy rice). The rice husk is currently used as fuel around the province generating rice husk ash (RHA) which causes environmental and health issues. This study focuses on surveying and analyzing the current situation for utilization, management, treatment, and awareness of enterprises and community about generated RHA via a household investigation method.

This study is concerned with low-input rainfed lowland rice cultivation systems in Cambodia where soil fertility is poor, rainfall uncertain, and fertiliser use limited. The investigation comprised a field survey and a series of experiments in the field and glasshouse.

Casamance is a region in southern Senegal that traditionally produces rainfed rice, but Senegal produces only 1/3 of its rice consumption. Lowland areas, where rice is primarily produced, have acid sulfate soils with low pH and potential aluminum and iron toxicity. The goal of this work was to determine if soil amendments can alleviate soil acidity, counteract the negative biogeochemical effects that occur in flooded conditions, and increase rice yield. A two-year experiment was conducted to test the following soil treatments – agricultural lime, pulverized oyster shell, biochar, and control (

Rice (Oryza sativa L.) is the most economically important crop in Cambodia providing smallholder farmers with food and income. Despite rice cultivation being widespread, rice yields in Cambodia are among the lowest in Southeast Asia. Cambodian farmers reported insect pests to be the leading cause of yield loss. To control pests, farmers are dependent on pesticides without any integrated pest management (IPM) options employed.

Abstract:

Questa tesi studia e valuta le tecniche agronomiche legate alla coltivazione del riso biologico nell'area del Nord Italia. Il finanziamento principale di questa tesi deriva dal progetto MIPAAF "Risobiosystems", iniziato nel 2017 e terminato nel 2020. Gli studi presentati sono collegati alla strategia europea di produzione alimentare sostenibile "Farm to Fork", che è il fulcro del Green Deal europeo per rendere i sistemi alimentari equi, sani e rispettosi dell'ambiente, incoraggiando l'espansione del settore dell'agricoltura biologica (Commissione europea 2020). Come riportato in letteratura,

Abstract:

While in the traditional agricultural management soil attributes variability used in the crop production has not been considered, the site-specific management aims to identify this variability. The main objective of the present work was to compare the site-specific management to the traditional management in the flooded rice crop describing the techniques and identifying economical and technicals factors that provide a viability analysis. For this reason, an experiment was carried out in a commercial flooded rice field with application of site-specific management techniques. The methodology

Abstract:

Sub-Saharan Africa is today facing a big challenge regarding food deficiency and water scarcity due to climate change. One of these countries is Rwanda, a small landlocked country in the middle of Africa. Rwanda strongly depend on agriculture, both in the aspect of reducing poverty and hunger but also because their economy security depend on it. Because of increasingly fluctuating rainfalls their agriculture becomes more dependent on irrigation and the availability to water resources. To investigate how the climate change will affect the amount of water resources in the coming decades, this st

Abstract:

A produção agrícola apresenta características particulares, se comparada a outras atividades da economia, sendo uma das mais marcantes a extensão dos riscos aos quais está exposta. O cultivo de arroz (Oryza sativa L.) irrigado, embora pareça menos suscetível a riscos do que as culturas de sequeiro, também está exposto aos riscos inerentes ao exercício da atividade agrícola. Maior produtor mundial de arroz fora da Ásia, o Brasil tem no estado do Rio Grande do Sul seu principal estado produtor, com 65% do total. O objetivo deste trabalho foi analisar como o orizicultor do Rio Grande do Sul perce
