“…On the other hand 'Charlot' F 1 , fertilized twice (V9) had a highest number of leaves, 16. These values are similar to those obtained by Bianco et al (2015) at autumn cauliflower varieties. Number of leafs also increased under different fertilizations options and it was between 13 cm at the unfertilized variant and 16 cm at the fertilized variant.…”

Use of manufactured fertilizers has been increasingly incorporated into regular farming practice in EU since its introduction in mid to late nineteenth century. In 2014, mineral fertilizer consumption in EU was 18 million tons. Given intensive use of fertilizers and pesticides, horticulture and vegetable growing are considered to be major contributors to some existing environmental impacts, such as water and soil pollution. Therefore farmers need to be aware and use only necessary amount of fertilizer for good plant development and to obtain high productions and to move from classical fertilization to organic fertilization. Cauliflower is not a pretentious culture but applying fertilizers can have a beneficial effect on production. Experience was carried out in 2016 in Apahida village, near Cluj-Napoca. It followed the effects of differentiated organic fertilization on three cauliflower hybrids: ‘Casper’ F1, ‘Cercy’ F1and ‘Charlot’ F1. Experiment was carried out in open field and was started with seedlings. Experimental factors were: hybrid and number of fertilizations. Each experimental factor had three graduations which combined resulted in a number of nine variants. During vegetation period, growth measurements were made and also the specific technology for autumn grown cauliflower in open field was applied.

“…This effect of N omission in reducing plant growth is widely reported in literature Bianco et al, 2015;Flores et al, 2015). An example of this type of study was performed in legumes Valeri et al (2014) verified a decrease in stem diameter and dry matter when compared to plants grown in a complete nutrient solution.…”

The inadequate supply of nutrients in sunn hemp comprises nutritional requirements and efficiency, causing a decrease in the growth and inducing specific nutritional disorders. For this reason this research sought to evaluate the effect of N, P, K, Ca and Mg restriction on nutrient accumulation, nutritional efficiency, plant growth and characterize the visual symptoms of nutrient deficiency in crotalaria. The experiment was conducted in a greenhouse in pots with constantly aerated nutrient solution. The experimental design was completely randomized with six treatments, corresponding to the complete nutrient solution (all nutrients) and omission of N, P, K, Ca and Mg individually, with three repetitions. The plant species used was sunn hemp juncea. When the particular nutrient deficiency symptom was defined, collection of the corresponding treatment plants was carried out to evaluate the stem diameter, leaf area, dry matter production of the root, shoot and entire plant, accumulation of N, P, K, Ca and Mg in the root, shoot and entire plant, efficiency of absorption and utilization of the nutrients studied and characterization of the visual deficiency symptoms of nutrients during the experimental period. The restriction of N, P, K, Ca and Mg in the cultivation of sunn hemp caused a reduction in plant growth and characteristic visual symptoms of nutritional deficiency of the respective nutrient. Deficiency of N and Mg caused greatest losses in growth of sunn hemp in relation to the other macronutrients due to lower capacity of the plant to use these nutrients in the production of dry matter when grown in the restrictive environment.

“…This could be influenced by the higher absorption of silicon by the plants, increasing the absorption of silicon cations (Chen et al, 2011). A different behavior was observed in figure 1D, where silicon accumulation was lower with increasing ammonium concentrations in roots, being higher with the presence of this element in the nutrient solution and NxSi** N** Si** NxSi** N** Si** NxSi** N** Si** at the same time been influenced because the ammoniacal N, causes different damages to the root system, such as reducing growth, turning plant to brown colors, and necrosis (Bianco et al, 2015). These authors suggested that the excess of ammonium also produces greater growth of vegetative buds compared to reproductive buds.…”

Response of radish seedlings (Raphanus sativus L.) to different concentrations of ammoniacal nitrogen in absence and presence of siliconRespuesta de las plántulas del rábano (Raphanus sativus L.) a diferentes concentraciones de nitrógeno amoniacal en ausencia y presencia de silicio ABSTRACT RESUMENThere are unknown thresholds about the effects of ammonia toxicity in the cultivation of radish and its prejudice is higher in the root than in the aerial part, been the use of silicon an alternative to mitigate this toxicity. The objective was to evaluate the response of radish crop to different concentrations of an ammonium nutrient solution in the absence and presence of silicon under greenhouse conditions. After 30 days of germination were evaluated photosynthesis, green color index, stomatal conductance, transpiration, leaf area, tap root diameter, dry matter accumulation of nitrogen and silicon in shoot parts and roots respectively. Ammonia toxicity in radish decreased photosynthesis, transpiration, and stomatal conductance, having greater prejudice in the dry matter accumulation of root and aerial part, this effect was mitigated with the presence of silicon in the nutrient solution.Existen dudas sobre los efectos de la toxicidad amoniacal en la fisiología del cultivo del rábano y su perjuicio es mayor en la raíz que en la parte aérea, siendo posible el uso del silicio para mitigar esa toxicidad. Para esto el objetivo fue evaluar la respuesta del cultivo del rábano en función de diferentes concentraciones de NH 4 + en la solución nutritiva en ausencia y presencia de silicio. Posterior a los 30 días de la germinación se evaluaron la fotosíntesis, índice de color verde, conductancia estomática, transpiración, área foliar, diámetro de la raíz, materia seca y acúmulos de nitrógeno y silicio respectivamente en la parte aérea y las raíces de las plantas. La toxicidad amoniacal en el rábano disminuyó la fotosíntesis, la transpiración y la conductancia estomática, habiendo mayor perjuicio en el acúmulo de la materia seca de la raíz y la parte aérea, siendo mitigado este efecto con la presencia de silicio en la solución nutritiva.Key words: beneficial element, abiotic stress, nitrogen; nutrient solution, vegetable.Palabras clave: elemento benéfico, estrés abiótico, solución nutritiva, hortaliza.Nitrogen is the second most required nutrient by vegetables. This element is mainly absorbed in form of nitrate or ammonium, and constitutes amino acids, proteins and enzymes. In this way, it exerts influence on the growth of plant species and on the production of reserve substances and maturation. Ammoniacal nitrogen can bring some benefits to plants, because it acts as an important intermediary in many metabolic reactions (Britto and Kronzucker, 2002), has lower energy expenditure for its metabolism, and dispenses the reduction phases, which are required to the absorption of NO 3 - (Hachiya et al., 2012). However, elevated concentrations of NH 4 + lead to several issues: induces toxicity in plants, may lead to chlorosis in leave...
