Abstract:

SummaryWest African flood-plains have undergone major land-use transformations in the second half of the 20th century. To obtain insight in the effect of flood-plain development for irrigated rice cultivation on the abundance, richness, and diversity of Palearctic and Afrotropical raptors, we conducted monthly transect surveys covering dry and wet seasons in four major habitats on the Waza-Logone flood-plain of Cameroon: dry grasslands, cultivated grasslands, rice fields, and seasonally flooded grasslands resembling natural flood-plain vegetation. We recorded 36 raptor species among 2,533 indi

Abstract:

To investigate production, oxidation, and emission of methane (CH4) in rice fields during the fallow and following rice seasons as affected by water management and rice straw incorporation in the fallow season, field and incubation experiments were carried out from November 2007 to November 2008. Four treatments, i.e. two water managements (flooded and drained) and two rates of rice straw application (0 and 4.8 t/ha), were laid out in a randomised block design. Results show that obvious CH4 production occurred in flooded fields in the late fallow season; consequently, fallow CH4 emission contr

Abstract:

AbstractDirect sowing of rice in a flooded paddy field is a beneficial cultivation practice for water use and labour efficiency, compared to the transplanted cultivation. However, a drastic reduction in seedling emergence under flooded paddy fields is a serious constraint especially when the seeds fell at deeper soil layers. Suitable rice germplasm for the direct sowing in flooded paddy fields could ensure the success of this cultivation practice. Instead of laborious field-based screening systems, a pot-based screening method was adopted for simplicity and efficient evaluation of seedling eme

Abstract:

Flooded rice (Oryza sativa L.) in south Florida is grown commercially in rotation with sugarcane and vegetables. From 2008 to 2018, rice production has doubled. During the spring-summer, nearly 200 km2 of fallow sugarcane land is available for rice production. In 2017, approximately 113 km2 of rice were planted in the region. The net value of growing rice as a rotation crop far exceeds its monetary return. This study evaluated soil health parameters before and after rice cultivation and compared them against two other common summer farming practices - fallow fields and flooded-fallow. The soil

Abstract:

Floods are significant global disasters, but their impact in developing countries is greater due to the lower shock tolerance, many subsistence farmers, land fragmentation, poor adaptation strategies, and low technical capacity, which worsen food security and livelihoods. Therefore, accurate and timely monitoring of flooded crop areas is crucial for both disaster impact assessments and adaptation strategies. However, most existing methods for monitoring flooded crops using remote sensing focus solely on estimating the flood damage, neglecting the need for adaptation decisions. To address these

Flooding in rice fields often occurs as a result of overflowing rainwater or overflowing river water. In addition, irrigation also often overflows and inundates farmers' fields. The way that is often done to overcome this is usually done every few minutes to the fields. An automatic tool is needed that can be used to be able to monitor water level activities that occur in rice fields. In that case farmers can make the best and timely decisions when rice fields will be flooded. The design process of this tool is carried out in 2 stages, namely the area analysis stage and the design of the tool

Abstract:

Conventional water and fertilizer management practices have led to elevated greenhouse gas emissions from rice fields and decreased the efficiency of water and fertilizer utilization in agricultural land. The implementation of water-saving irrigation and the substitution of chemical fertilizers with organic alternatives can influence CH4 and N2O emissions in rice fields. However, it remains unclear how the simultaneous application of both methods will affect the CH4 and N2O emissions in rice fields. Therefore, two irrigation methods (F: flooded irrigation; C: controlled irrigation) and three f

Abstract:

Many studies have been performed to compare different straw-returning methods that could provide environmental benefits. However, few studies have focused on the greenhouse gas emissions from straw returning under winter water-stored fields (flooded conditions) and winter fallow fields (non-flooded conditions), which are the common land use types after the rice harvest in southern China. Thus, in the present microcosm incubation experiment, CO2, CH4 and N2O emissions were compared under flooded and non-flooded soil conditions, following straw incorporation. Straw application stimulated CO2 cum

Abstract:

Rearing habitat for juvenile Chinook Salmon (Oncorhynchus tshawytscha) in California, the southernmost portion of their range, has drastically declined throughout the past century. Recently, through cooperative agreements with diverse stakeholders, winter-flooded agricultural rice fields in California’s Central Valley have emerged as ecologically functioning floodplain rearing habitat for juvenile Chinook Salmon. From 2013 to 2016, we conducted a series of experiments examining methods to enhance habitat benefits for fall-run Chinook Salmon reared on winter-flooded rice fields in the Yolo Bypa

Abstract:

Assessing belowground plant competition is complex because it is very difficult to separate weed and crop roots from each other by physical methods. Alternative techniques for separating crop and weed roots from each other are needed. This article introduces a stable isotope method that can quantify the amounts of roots of rice and barnyardgrass intermixed in flooded field soils. It relies on the biological principle that rice, a C3 (photosynthetic pathway) species, discriminates more effectively than barnyardgrass, a C4 species, against a relatively rare isotopic form (13C) of CO2.

An investigation was conducted to assess the efficacy and crop tolerance of Almix 20WP, a herbicide premix of metsulfuron-methyl and chlorimuron-ethyl, for controlling sedges and broadleaf weeds in flooded rice fields. Treatments included various rates of Almix 20WP, 2,4-D, Bentazone-sodium, Bispyribac-sodium, and a tank-mix of Almix 20WP (40 g/ha) with 2,4-D (1000 g/ha). Almix 20WP at 60 g/ha significantly reduced weed biomass and density. Bentazone-sodium treated rice yielded the highest grain (7975.0 kg/ha), with the tank-mix of Almix 20WP and 2,4-D provided the second-highest (7962.5 kg/ha

Reducing methane (CH4) emissions and water use in irrigated rice systems while maintaining production to feed the ever-increasing population is vital in Bangladesh. Different rice establishment methods viz. alternate wetting & drying (AWD), system rice intensification (SRI) and direct wet seeded rice (DWSR), have a promising mitigation potential to reduce CH4emission compared to continuous flooded (CF) rice fields.
