Tolerance mechanisms and irrigation management to reduce iron stress in irrigated rice

Improved irrigation management is identified as a potential mitigation option for methane (CH4) emissions from rice (Oryza sativa). Furrow-irrigated rice (FR), an alternative method to grow rice, is increasingly adopted in the Mid-South U.S. However, FR may provide a potential risk to yield performance and higher emissions of nitrous oxide (N2O). This study quantified the grain yields, CH4 and N2O emissions from three different water management practices in rice: multiple-inlet rice irrigation (MIRI), FR, and FR with cereal rye (Secale cereale) and barley (Hordeum vulgare) as preceding winter cover crops (FRCC). CH4 and N2O fluxes were measured from May to September 2019 using a static chamber technique. Grain yield from FR (11.8 Mg ha−1) and MIRI (12.0 Mg ha−1) was similar, and significantly higher than FRCC (8.5 Mg ha−1). FR and FRCC drastically reduced CH4 emissions compared to MIRI. Total seasonal CH4 emissions decreased in the order of 44 > 11 > 3 kg CH4-C ha−1 from MIRI, FR, and FRCC, respectively. Cumulative seasonal N2O emissions were low from MIRI (0.1 kg N2O-N ha−1) but significantly higher from FR (4.4 kg N2O-N ha−1) and FRCC (3.0 kg N2O-N ha−1). However, there was no net difference in global warming potential among FR, FRCC and MIRI. These results suggest that the increased N2O flux from furrow-irrigated rice may not greatly detract from the potential benefits that furrow-irrigation offers rice producers.

Meloidogyne Graminicola

The irrigated rice production can be limited by various phytopathogenic agents, including root-knot nematodes (Meloidogyne spp.). Thus, the aim of this research was to check the host suitability of plant species most often found off-season and during rice cultivation, to root-knot nematode Meloidogyne graminicola, under two irrigation managements. Two experiments were conducted in a completely randomized design. In the first experiment seven plant species that occur in an area of rice cultivation, in fallow, off-season were evaluated. For the second experiment nine weed species infesting the irrigated rice culture were tested in rainfed and flooding conditions. The sixteen species, kept individually in pots with sterilized substrate, were inoculated with 5,000 eggs and second stage juveniles (J2) of nematode. BRS 410 IRGA rice plants inoculated with M.graminicola were used as control. Two months after inoculation, the root system of each plant was evaluated for number of galls and nematode reproduction factor. It was verified that the species of off-season of rice cultivation Sida rhombifolia, Raphanus raphanistrum, Spergula arvensis, Lotus corniculatus and Trifolium repens, and, during the cycle of rice cultivation, Aeschynomene denticulata, Leersia hexandra, are immune to nematode. The plant species off-season, Avena strigosa and Lolium multiflorum and of cultivation, Alternanthera philoxeroides, red rice, Echinochloa crusgalli, Cyperus difformis, Cyperus esculentus, Cyperus iria and Fimbristylis miliacea would behave as hosts of M.graminicola, mostly under rainfed conditions.

Water Recycle

With the continuous climate change we are experiencing; extreme heat, drought, and declining water supplies that affect our rain fed and irrigation systems resulting to a higher demand for water for evaporation and evapotranspiration by crops which lead to more frequent soil moisture deficit which is unavoidable and there are still other factors that contributes to water head loss. This make it necessary to find out novel ways to resolve the issues regarding irrigation management. Though there are many existing innovative water management ideas available out there, but it takes to shed huge amounts of government funds to implement. This study consists of designing a water-recycle model to efficiently use the limited water supply and further attain to serve the total surface area of irrigated rice. The proposed design uses a renewable energy that pumps out water from the catch basin back to its water source, this method entirety use the most out of the water supply to lessen water wastage and water shortage and to maximize water saving in the area.

Water scarcity has become one of the highest risks for environmental and economic security worldwide. The water footprint for rice production, i.e., the total volume of freshwater consumed to produce a unit quantity rice has been estimated for three different agroclimatic zones of Punjab for the years 2000 to 2017. The results revealed that effective rainfall (Peff) improved in later years due to a change in crop calendar,legally enforced by an Act prohibiting the transplanting of paddy before a specified date. During the period of study, minimum crop evapotranspiration (ETc) was 4645 and maximum was ETc of 9511 m3ha-1 during 2014 and 2011, respectively. The green water footprint (WFgreen) for rice varied from 646litreskg-1of rice during low rainfall years (2012) to 1149 litre kg-1 of rice during heavy rainfall (1192 mm) during 2011.Out of a total water footprint (WFtotal) of 2650 litre kg-1, the share of blue water footprint (WFblue) was higher 1804 litre kg-1 (68%), indicating a need to improve on-farm irrigation management to conserve water resources.

O manejo da água na orizicultura é complexo, sendo os estudos acerca da pegada hídrica do arroz menos frequentes em relação a outras culturas. O objetivo deste trabalho foi estimar de forma simplificada a pegada hídrica do arroz irrigado por aspersão e inundação sob diferentes manejos de irrigação, adotando como base a metodologia tradicional de estimativa da pegada hídrica. Os dados utilizados são provenientes de dois experimentos conduzidos na Estação Experimental Terras Baixas, Empresa Brasileira de Pesquisa Agropecuária (Embrapa) Clima Temperado, Capão do Leão, RS, Brasil. No Experimento 1 foram analisados três manejos de irrigação na safra do arroz de 2011/2012 e quatro na safra de 2012/2013. No Experimento 2 foram analisados quatro manejos de irrigação nas safras 2015/2016 e 2016/2017. Os manejos nas tensões de 20 e 10 kPa (aspersão) e por irrigação contínua (inundação) apresentaram menor pegada hídrica simplificada. Comparando-se a irrigação por aspersão e inundação, concluiu-se que na inundação, o manejo de irrigação contínua resultou em uma pegada hídrica simplificada menor.

WATER FOOTPRINT OF RICE CULTIVATED UNDER DIFFERENT IRRIGATION MANAGEMENTS 2 ABSTRACT Rice is one of the most produced and consumed cereals in the world. The water management in rice farming is complex, and studies on the rice water footprint are less frequent than other cultures. The objective was to estimate the simplified water footprint of a sprinkler and flood-irrigated rice under different irrigation management, taking as model the traditional methodology of water footprint estimation. The raw data used are from two experiments performed using rice in the “Terras Baixas”, Experimental Station, Brazilian Agricultural Research Corporation (Embrapa) Temperate Climate, located in Capão do Leão, RS, Brazil. In Experiment 1, three irrigation management applied in the rice cropping season of 2011/2012 and four in the cropping season of 2012/2013 were analyzed. In Experiment 2, four irrigation managements in the 2015/2016 and 2016/2017 cropping seasons were evaluated. The irrigation managements in the tensions of 20 and 10 kPa (sprinkler) and continuous irrigation (flood) presented smallest simplified water footprint. Comparing sprinkler and flood irrigation, it can be concluded that the flood method, under continuous irrigation, resulted in a smallest simplified water footprint.

Soil And Water

Proper irrigation management is critical to conserve and protect water resources and to properly manage nutrients in the home landscape. How lawns and landscapes are irrigated directly impacts the natural environment, so landscape maintenance professionals and homeowners must adopt environmentally-friendly approaches to irrigation management. After selecting the right plant for the right place, water is the next critical factor to establish and maintain a healthy lawn and landscape. Fertilization is another important component of lawn and landscape maintenance, and irrigation must be applied correctly, especially following fertilization, to minimize potential nutrient losses. This publication supplements other UF/IFAS Extension publications that also include information on the role of soil and the root zone in irrigation management. This publication is designed to help UF/IFAS Extension county agents prepare materials to directly address nutrient losses from lawns and landscapes caused by inadequate irrigation management practices.

Citrus Production

Water is a limiting factor in Florida citrus production during the majority of the year because of the low water holding capacity of sandy soils resulting from low clay and the non-uniform distribution of the rainfall. In Florida, the major portion of rainfall comes in June through September. However, rainfall is scarce during the dry period from February through May, which coincides with the critical stages of bloom, leaf expansion, fruit set, and fruit enlargement. Irrigation is practiced to provide water when rainfall is not sufficient or timely to meet water needs. Proper irrigation scheduling is the application of water to crops only when needed and only in the amounts needed; that is, determining when to irrigate and how much water to apply. With proper irrigation scheduling, yield will not be limited by water stress. With citrus greening (HLB), irrigation scheduling is becoming more important and critical and growers cannot afford water stress or water excess. Any degree of water stress or imbalance can produce a deleterious change in physiological activity of growth and production of citrus trees. The number of fruit, fruit size, and tree canopy are reduced and premature fruit drop is increased with water stress. Extension growth in shoots and roots and leaf expansion are all negatively impacted by water stress. Other benefits of proper irrigation scheduling include reduced loss of nutrients from leaching as a result of excess water applications and reduced pollution of groundwater or surface waters from the leaching of nutrients. Recent studies have shown that for HLB-affected trees, irrigation frequency should increase and irrigation amounts should decrease to minimize water stress from drought stress or water excess, while ensuring optimal water availability in the rootzone at all times.
