“…Its addition to the culture medium generally augments these parameters, but occasionally, beyond certain concentrations, Ca can trigger tolerance problems that harm the plant. 12 Therefore the objective of the present work was to evaluate the impact that various Ca levels in a nutrient solution had on nutrient element concentrations and biomass production in tobacco plants. The plants were sampled at the 14-leaf stage just before the onset of¯owering, 105 days after sowing.…”

The aim of this work was to analyse the dynamics of the nutritional state and biomass production in tobacco plants resulting from the application of various calcium levels (Ca1, 1.25 mol m À3 CaCl 2 ; Ca2, 2.50 mol m À3 CaCl 2 ; Ca3, 5 mol m À3 CaCl 2 ) in the culture medium. Tobacco plants were grown under controlled conditions and submitted to regular fertilisation with macro-and micronutrients. The concentrations of Ca, organic N, P, K, Na, Mg, Fe, Mn, Zn, Cu, Cl and B were determined in the roots and leaves. As expected, Ca accumulated progressively with increasing concentration of this element in the culture medium. There was a slight rise in the concentration of organic N but hardly any change in the concentrations of K and Na. In contrast, increasing Ca application caused a gradual decline in P and Mg concentrations. In terms of micronutrient concentrations, Fe, Mn, Zn, Cl and B were in¯uenced positively by Ca treatment. A noteworthy synergetic relationship was found between Ca and B. In contrast, the Cu concentration in the roots declined signi®cantly with increasing Ca application. The effect of Ca on biomass production depended on the organ analysed, since the dry matter content diminished in the roots but was augmented slightly in the leaves.

“…In different works on tobacco plants ( , ) there has been observed an inversely proportional relationship between foliar biomass production and increased applications/foliar concentrations of Ca 2+ and Cl - . In our experiment, the highest foliar biomass production was recorded in the T1 treatment, some 123% higher than the lowest value, which was in T3 ( P ≤ 0.001; Figure ).…”

“…Of these nutrients, Ca 2+ appears to have a major impact in tobacco cultivation. For example, Sims et al (12) observed that an incremental soil application of Ca 2+ from 0 to 380 Kg/ha resulted in gradual increase of the foliar and total biomass, but application of 760 Kg/ha drastically diminished biomass production of the tobacco plants. Similar results have been found by Ruiz et al (13) in tobacco plants, reporting decreased foliar biomass production after applications of high dosages of Ca 2+ (5 mM).…”

The aim of the present work was to determine the influence of different CaCl(2) dosages on foliar biomass and quality of tobacco plants (Nicotiana tabacum L. var. Tennesse 86). Plants were grown under controlled conditions and submitted to regular fertilization with macro- and micronutrients. The CaCl(2) was applied to the nutrient solution at 1.25 mM (T1), 2.5 mM (T2), and 5 mM (T3). The results indicated that, under the experimental conditions of this work, the application of 1.25 mM of CaCl(2) favored the growth and development of the leaves, this leading to improved biomass production in tobacco leaves. The increase in foliar biomass in treatment T1 could largely be a result of the stimulation of NO(3)(-) assimilation. However, this situation has negative consequences for tobacco quality, given that the T1 treatment augmented the NO(3)(-) concentration and the foliar concentration of nicotine (both effects being harmful for human consumption) and decreased the concentration of reducing sugars in leaves of tobacco plants compared with those of T2 and T3. Finally, a close and directly proportional relationship was found in our experiment between the parameters of foliar-biomass production, total N concentration, chlorophyll concentration, and decline in quality.

“…Many researchers (Garner et al, 1930;Sims et al, 1995;Spiers and Braswell, 1994) reported that high calcium concentrations in solution or in field soils sometimes limit magnesium accumulation and may elicit magnesium deficiency symptoms). In tomato, the magnesium concentration in shoots (Gunes and Alpaslan, 1998) and fruits (Paiva et al, 1998) decreased as the calcium fertilization rate increased.…”

Experiment was conducted to evaluate media mix ratios (various soil: sand: and decomposed FYM proportions) and to study the effect of supplementary nitrogen (0 and 25 kg N ha phosphorous (0 and 23 kg P ha -1 ) for container grown tomato crop during the rainy season under field condition at Melkassa Agricultural research, Ethiopia. Three factors, namely, media proportions; supplementary N and P applications rates were combined fac replications. Data on canopy characteristics such as plant height, stem diameter, main lateral branch length, canopy width, canopy depth were measured from sample plants and canopy cover was estimated. Additionally, tomato early blight data were analysed using SAS. The results indicated that use of media mix ratios in combination with application of starter P fertilizer had a significant effect on shoot fresh weight, canopy diameter and marketable fruit number where as application of starter N had highly significant influence on canopy width, leaf fresh weight, leaf dry weight, leaf area and canopy cover. Similarly, application of starter N had significant effect on mean marketable fruit number. Thus, based on the results of this study the proposed media mixes is MR3 (4:1:1) that suits organic tomato production. Although there was no significant difference between supplementary application of 25 kg N ha -1 and no N application for container grown tom the rate of 25 kg ha -1 was found to be better yielding. Similarly, compared to 0 kg P ha application of 23 kg P ha -1 produced higher fruit yield. Although there was increase in fruit yields of tomato crop, further research is required for management of supplementary N and P fertilizer uses in container grown tomato cultivation under both rainfed and irrigated conditions.
