    Effect of Reaction-Finished Solution of Hydrochar (HRFS) Application on Rice Grain Yield and Nitrogen Use Efficiency in Saline Soil

    Zhenghua Yi1, Paramsothy Jeyakumar2, Jiang Jiang1, Xiaomian Zhang3, Chunlei Yue3, Haijun Sun1,*

    Phyton-International Journal of Experimental Botany, Vol.91, No.4, pp. 859-868, 2022, DOI:10.32604/phyton.2022.018396

    Abstract We conducted a pot experiment to examine the feasibility of applying a reaction-finished solution of hydrochar (HRFS) to enhance rice production in a saline soil. With this purpose, HRFS was applied (0, 10, 20, 40, 60, 80 and 100 mL/pot) and rice yield and nitrogen (N) use efficiency (NUE) were determined. HRFS application significantly (P <0.05) increased rice grain yield by 19.6%–30.0% compared to the control treatment (CKU, with N but without HRFS addition). Moreover, HRFS application promoted plant height and straw biomass of rice. Increases of rice yield were mainly achieved by increases in the number of panicles and grains… More >

    Effect of propagule size and plant density on seedling emergence, yield and quality of garlic (Allium sativum L.)

    Jiménez-Vázquez P1, JA Rangel-Lucio2, M Mendoza-Elos1, F Cervantes-Ortíz1, JG Rivera-Reyes1

    Phyton-International Journal of Experimental Botany, Vol.83, pp. 83-91, 2014, DOI:10.32604/phyton.2014.83.083

    Abstract The production and quality of garlic (Allium sativum L.) depend on agronomics management, physiological and sanitary characteristics of bulbs or bulbils used at sowing, and economic resources. The objective of this assay was to evaluate the effects of garlic bulb and bulbil sizes, and of plant density, on seedling emergence, and garlic bulb yield and quality cv. Taiwan. The garlic bulbs and bulbils classified and selected by size were made from Extra Flor, Gigante and Jumbo garlic bulbs. They were sown at three plant densities (333000, 285710 and 250000 plants/ha) in a split plot experimental design. During garlic growth, the… More >

    Toxicity and accumulation of arsenic in wheat (Triticum aestivum L.) varieties of China

    Zhang1 WD, DS Liu2, JC Tian1*, FL He1

    Phyton-International Journal of Experimental Botany, Vol.78, pp. 147-154, 2009, DOI:10.32604/phyton.2009.78.147

    Abstract Soil arsenic contamination becomes a potential agricultural and environmental hazard worldwide, and has been a serious problem for safe food production. A field experiment on soil contamination was conducted on four wheat varieties (Jimai, Gaoyou, Weimai and Wennong) in Eastern China, using 50 or 100 mg arsenic/kg soil. Biomass production and yield components were determined and arsenic concentrations were measured in plant tissues. Differential arsenic effects on wheat varieties were determined at maturity. Results showed that addition of arsenic significantly (p<0.05) reduced root, stem and spike dry weight and yield components, which resulted in the decrease of grain yield per… More >

    Forage characteristics for double purpose wheats

    Morant AE, HD Merchán, EE Lutz

    Phyton-International Journal of Experimental Botany, Vol.76, pp. 95-102, 2007, DOI:10.32604/phyton.2007.76.095

    Abstract Length of the vegetative period and forage production were evaluated in ten commercial, long term cycle wheat varieties: Buck Charrúa, Cooperación Nanihué, Buck Cacique, Cooperación Maipún, Buck Catriel, ProINTA Pigüé, Buck Poncho, ProINTA Pincén, ProINTA Super and Cooperación Liquén. The study was conducted in the experimental field of the Departmento de Agronomia, Universidad Nacional del Sur, Bahía Blanca, Argentina, under dry land conditions. A completely Randomized Block Design with five replicates was used. Seeding was effected on 9 April 1996. From the time the plant had three leaves to the Double Ridge (DA) apex stage, the apex development, tiller number… More >

    Double-purpose wheat production and its association with a short-cycle wheat

    Lutz EE, HD Merchán, AE Morant*

    Phyton-International Journal of Experimental Botany, Vol.75, pp. 85-89, 2006, DOI:10.32604/phyton.2006.75.085

    Abstract Management of a double purpose wheat is not easy. Therefore, a simpler management alternative was studied: the mixture of two wheat varieties, one of long- cycle and the other one of short-cycle. Research was effected in the experimental field of the Asociación of Cooperativas Argentinas (38º 36´S, 61º 58´O and 122 m asl), 15 Km SW of Cabildo (Bs. As), in the semi-arid wheat subregion V S. At this place, forage and grain production of a suitable double-purpose wheat (ProINTA Pincén) was compared to its mixture with a short-cycle variety (Cooperación Calquín), either in the same or alternating rows. Forage… More >

    The influence of soil compaction and conservation tillage on sunflower’s (Helianthus annuus L.) below ground system

    Mirleau-Thebaud V1,2, J Dayde1, JD Scheiner1,3,4

    Phyton-International Journal of Experimental Botany, Vol.86, pp. 53-67, 2017, DOI:10.32604/phyton.2017.86.053

    Abstract Soil compaction represents an important issue in the actual context of agricultural system sustainability. Research on the various developments of root systems under tillage has been explored for many crops, whether for the biomass area or the underground, but very little concerns Sunflower (Helianthus annuus L.). The objectives of the study were to understand the impact of soil tillage and of the induced mechanically compacted soil on: i) sunflower’s root system architecture, ii) biomass area iii) production. Two complementary experiments were realized in the south of France (France’s main sunflower production area). In both experiments, increased resistance of the soil… More >
