The cultivated area of soybean has increased worldwide in past decades, including regions with saline soils, strongly decreasing growth and productivity. use amino acids (AAs) as buffering compounds against stressful conditions can be a useful strategy to mitigate salt stress these regions. This study aimed evaluate the effects foliar application AA mixtures on growth, physiology, biochemistry traits salt-stressed plants. A pot experiment was designed factorial scheme (4 × 3) randomized...
Soybean is widely cultivated around the world, including regions with salinity conditions. Salt stress impairs plant physiology and growth, but recent evidence suggests that silicon (Si) able to mitigate this stressful condition. Therefore, purpose of study was evaluate how different strategies Si application impact on salt tolerance an intermediate accumulator species (soybean). we applied four treatments: Si-untreated plants (Si 0); foliar spraying at 20 mmol L-1 F); nutritive solution...
Nitrogen (N) holds a prominent position in the metabolic system of plants, as it is main constituent amino acids, which are basic building blocks proteins and enzymes. Plants primarily absorb N form ammonium (NH4+) nitrate (NO3−). However, most plants exhibit severe toxicity symptoms when exposed to NH4+ sole source. Addressing stress requires effective strategies, use silicon (Si) has shown promising results. there lack underlying studies on impact C:N:P stoichiometric balance role Si these...
El objetivo de esta investigación fue evaluar los efectos la densidad plantas combinado con diferentes fertilizantes en las respuestas agroproductivas del maní (Arachys hipogea L.). Un experimento se desarrolló condiciones campo y tratamientos arreglaron parcelas subdivididas, un diseño bloques al azar tres réplicas. Los dos densidades (83000 95000 ha-1) fertilizantes: aplicación foliar aminoácidos (As; 0,25 L ha-1), inoculación suelo Microorganismos eficientes (ME; 100 mL m-2), estiércol...
El cambio climático representa una amenaza significativa en el presente y futuro para los agroecosistemas. acelerado crecimiento de la población mundial ha incrementado demanda alimentos, lo que a su vez llevado un uso intensivo fertilizantes químicos plaguicidas control plagas. Esta práctica, sin embargo, compromete calidad del suelo puede tener consecuencias devastadoras productividad agrícola. En este contexto, las prácticas agroecológicas emergen como estrategia viable preventiva mitigar...
There are unknown thresholds about the effects of ammonia toxicity in cultivation radish and its prejudice is higher root than aerial part, been use silicon an alternative to mitigate this toxicity. The objective was evaluate response crop different concentrations ammonium nutrient solution absence presence under greenhouse conditions. After 30 days germination were evaluated photosynthesis, green color index, stomatal conductance, transpiration, leaf area, tap diameter, dry matter...
Abstract Temperature and other abiotic factors, such water nutrient availability, play an important role for plants in response to the changing environments. At this regard, both warming drought might affect use efficiency (NUE) growth of Megathyrsus maximus a C4 forage grass high interest cattle feeding. However, requirements species under climate change are unknown. Therefore, we aimed evaluate individual combined effects two levels temperature: ambient elevated temperature (2°C above...
Abstract BACKGROUND High concentrations of ammonium as the sole nitrogen source may result in physiological and nutritional disorders that can lead to reduced plant growth toxicity. In this study, we hypothesized toxicity radish seedlings ( Raphanus sativus L.) might be mitigated by incorporation silicon (Si) into applied nutrient solution. To examine possibility, conducted a hydroponic experiment evaluate effects five (1, 7.5, 15, 22.5, 30 mmol L −1 ) on photosynthesis, green color index,...
Con el objetivo de evaluar la asociación entre diferentes formas aplicación microorganismos eficientes y inoculación con Rhizobium en comportamiento morfológico productivo del frijol común se desarrolló un experimento Cooperativa Créditos Servicios “Mártires Taguasco”, Sancti Spíritus, Cuba, octubre 2012 a febrero 2013 utilizó cv. Cuba cueto. Fueron evaluados dos factores, primero fue utilización (sin 1 kg/46 kg semilla) segundo cuatro eficientes, sin (0), al surco (100 mg/L), foliares mg/L)...
The use of Efficient Microorganisms (EM) can be an effective alternative to improve plant growth and yield in the bean cultivation. Therefore, different forms application efficient microorganisms were evaluated production two cultivars common from November 2013 March 2014. Two factors studied; first one was comprised cultivars, Velazco Largo (VL) Cuba Cueto (CC-25-9-N). second factor consisted four treatments with EM; without EM (control), soil inoculation (100 mL L-1), foliage applications...
Con el objetivo de evaluar la respuesta agroproductiva habichuela a aplicación los bioproductos vermicompost lixiviado (VL) y microorganismos eficientes (ME) en condiciones organoponía, fue realizado este estudio organopónico “El Estadio”, Sancti Spíritus, Cuba, febrero mayo 2016. La siembra variedad Verlili ejecutada distancia 80 cm entre líneas 20 plantas. Los tratamientos fueron distribuidos bloques al azar, esquema factorial 2×2, evaluándose ausencia presencia (100 mL L-1) ambos...
The use of plants biostimulants jointly with efficient microorganisms maybe an alternative to change the plant metabolism and consequently, improve bean crop yield. Under this circumstance, it’s evaluate effect between Fitomas E in productive increase common two sowing periods. Two experiments were developed, from October 2014 April 2015. treatments applied were, a control, inoculation foliar applications microorganisms, association these. indicators evaluated were: number leaves per plant,...
El crecimiento exponencial de la población mundial hace necesario buscar alternativas para incrementar producción alimentos. Los aminoácidos se utilizan ampliamente mejorar productividad los cultivos, sin embargo, en el cultivo remolacha roja no está generalizado su uso. Por lo que objetivo investigación fue evaluar efecto aplicación foliar una solución índices fisiológicos y roja. Se diseñó un experimento bloques al azar con cinco tratamientos seis réplicas. Fueron evaluadas cuatro...
The use of adequate plant density in combination with the amino acid application can play a decisive role achieving optimal yields sesame crops. In order to evaluate effects influence densities and acids on growth yield seeds rainy season, an experiment was carried out between June October 2023. Three doses (AV) were examined: without VA, 0.25 0.50 L ha-1 two (25,000 29,000 plants/ha), distributed Split-plots, randomized block design three replications. results showed that crop, 25,000...
This research aimed to explore the effects of Silicon (Si) on managing hydrogen peroxide levels, photosynthetic pigment content, nutrient accumulation, and production root shoot dry biomass in salt-stressed sunflower (Helianthus annuus L.) plants. Conducted a glasshouse, experiment followed completely randomized block design factorial arrangement (2 × 2) five replicates. Pots were divided into two groups: non-salt stressed, salt stressed (100 mM NaCl), both with Si as stabilized sodium...
Silicon (Si) has been extensively studied for its ability to decrease sodium (NaCl) toxicity in various plant species. Nonetheless, the processes that drive these responses are still not well understood.
