The cDNA coding for a cytoplasmic aldolase (cALD) of rice plant (Oryza sativa L. cv. Nihonbare) was cloned by screening from rice cDNA library with a cDNA probe (pMX71) specific to the maize cALD, kindly supplied by Freeling.M. (1). The sequence of two overlapping cDNA clones contained an open reading frame coding for a protein of 358 amino acids. Of the deduced amino acid sequence, 92% was ide...

The impacts of integrated soil fertility management (ISFM) in conservation agriculture need short-term evaluation before continuation its long-term practice. A split-split plot experiment with tillage (minimum tillage, MT vs. conventional CT) as the main plot, residue (20% residue, R no a control, NR) sub-plot, and compost (Trichocompost, LC; bio-slurry, BS; recommended fertilization, RD) sub-s...

Sugar recognition specificities of class III (OsChib1a) and class I (OsChia1cDeltaChBD) chitinases from rice, Oryza sativa L., were investigated by analyzing (1)H- and (13)C-nuclear magnetic resonance spectra of the enzymatic products from partially N-acetylated chitosans. The reducing end residue of the enzymatic products obtained by the class III enzyme was found to be exclusively acetylated,...

The effects of thermochemical pretreatment and continuous thermophilic conditions on the composting of a mixture of rice straw residue and cattle manure were investigated using a laboratory-scale composting reactor. Results indicate that the composting period of rice straw can be shortened to less than 10 days by applying alkali pre-treatment and continuous thermophilic composting conditions. T...

In this study, we aimed to analyze changes in the residual levels of buprofezin during milling, washing, cooking, and processing rice make porridge, cakes, cookies. The pesticide residue were analyzed using high-performance liquid chromatograph with UV detector. level brown was 21.8 mg/kg, after that polished 1.73 elimination 92.1% residue. rate reduction washing 21.6-57.3%, decreased by 27.4-6...

Residue management in cropping systems is useful to improve soil quality. However, the studies on the effects of residue management on methane (CH4) and nitrous oxide (N2O) emission from paddy field in southern China are few. Therefore, the emissions of CH4 and N2O were investigated in double cropping rice (Oryza sativa L.) systems with different winter covering crops using the static chamber-g...

In order to promote the efficient and coordinated utilization of water nitrogen in rice, the  15 N missing technology experiment was adopted study effects application rate (N 0 , 160 200 240 ) irrigation mode (Wet-dry alternation, conventional irrigation) on absorption, transport, residue, loss super rice. The results showed that with increase rate, accumulation fertilizer total rice plant...

AbstractThis study investigated the hydric and durability performances of compressed earth blocks (CEBs) stabilized with calcium carbide residue (CCR) rice husk ash (RHA). Dry mixtures were pre...
