Abstract:The aim of conducted in years 2008-2012 studies was to assess the efficiency of application of increasing manganese levels on the nutritive value of tomato fruits (Lycopersicon esculentum Mill. cvs. 'Alboney F1' and 'Emotion F1'), expressed in the contents of macro-and micronutrients. Plants were grown in rockwool with application of nutrient solution characterized the following chemical composition (in [mg dm

“…The use of NH 4 as a nitrogen source can increase plant growth and fruit sugars content but decreases fruit size and marketable yield due to a reduction of calcium and magnesium absorption and an increase in the number of fruit affected by BER [84,95,157]. Generally, nitrogen supply in the form of NH 4 should be lower than 10% of total nitrogen in order to minimise the susceptibility of fruit to BER [8] and fruit with gold specks [147,184].…”

Influence of electric conductivity management on greenhouse tomato yield and fruit quality

-The osmotic and ionic effects of the electrical conductivity (EC) of the nutrient solution and its interactions with climatic factors and cultural practices on tomato yield and fruit quality are reviewed. Adjusting the salinity of the nutrient solution allows growers to modify water availability to the crop and hence improve fruit quality. At some point, however, increases in salinity limit marketable yield. Under high ECs, fruit size is inversely related to EC while the dry matter content of the fruit is linearly increased by the EC. The exact rate of yield decline varies with interactions between cultivars, environmental factors, composition of the nutrient solution, and crop management. According to different studies and growth conditions, salinities higher than 2.3-5.1 mS⋅cm -1 result in an undesirable yield reduction, while ECs of 3.5-9.0 mS⋅cm -1 improve tomato fruit quality. Manipulating the indoor climate such as humidity, temperature and ambient CO 2 level may offset the negative effect of high salinity on yield and fruit quality such as blossom-end rot. The light intensity received by the plant directly affects the quantity of photoassimilates available to the fruit, it also increases their sugar: acid ratio, and influences the transpiration rate and the water uptake by the plant, which in turn, affect the EC around the root. Increasing the EC with NaCl reduces titratable acids, potassium and nitrogen in the fruit but also increases their sodium content. NaCl enhances the sweetness of tomato fruit and improves the overall flavour intensity. Depending upon the composition of the saline solution, ion toxicities or nutritional deficiencies may arise because of a predominance of specific ion or competition effects among cations and anions. Keeping the proper nutrient levels and ratios between all the nutrients in the root environment for each growth stage of a crop should be targeted in order to achieve high yields and high quality products throughout the cropping season. Several EC and fertigation management regimes could improve fruit quality and are presented in this review.Lycopersicon esculentum / tomato / electrical conductivity / salinity / fruit quality / greenhouse Résumé -Influence de la régie de la conductivité électrique de la solution nutritive sur le rendement et la qualité de la tomate de serre. Cette revue de littérature porte sur les effets osmotiques et ioniques de la conductivité électrique (CE) de la solution nutritive et de ses liens avec les facteurs climatiques et culturaux sur le rendement et la qualité de la tomate de serre. L'ajustement de la salinité de la solution nutritive permet aux producteurs de modifier la disponibilité en eau pour la plante de façon à contrôler la qualité des fruits. Cependant, des salinités élevées affectent le rendement vendable. Sous une haute CE, le calibre des fruits est inversement relié à la CE alors que le contenu en matière sèche des fruits augmente linéairement avec la CE. Le taux de réduction du rendement varie selon les interactions e...

This trial was carried out to establish an appropriate nutrient solution for Aglaonema commutatum and to investigate the nutritional effects generated by modifications in the solution. Six treatments were tested: control (T 0 ; pH 6.5, E.C. 1.5 dS m 21 , 6 mmol L 21 NO 3 2 -N, and 6 mmol L 21 K þ ); high nitrogen (N) level (T 1 ; 9 mmol L 21 6:3 NO 3 2 -NH 4 þ ); N form (T 2 ; 6 mmol L 21 N-NH 4 þ ); high K þ level (T 3 ; 12 mmol L 21 K þ ); high electrical conductivity (T 4 ; E.C. 4 dS m 21 , 25 mmol L 21 NaCl), and basic pH (T 5 ; pH 8). At the end of the cultivation, leaf, shoot, and root dry weights and elemental concentrations were determined. Nutrient contents and total plant uptake were calculated from the dry weights and nutrient concentrations. Plant K þ uptake increased with application of K þ or basic nutrient solution. The uptake and transport of calcium (Ca) were enhanced by the use of NO 3 2 -N and inhibited by the presence of other cations in the medium (NH 4 þ , K þ , Na þ ) and by basic pH. Magnesium (Mg) uptake increased with NO 3 2 -N application and with pH. Sodium (Na) uptake was the highest in the saline treatment (T 4 ), followed by the basic pH treatment. Sodium accumulation was detected in the roots (natrophobic plant), where the plant generated a physiological barrier to avoid damage. Dry weight did not differ significantly (p , 0.05) among treatments except in the NaCl treatment. These results may help in the formulation of nutrient solutions that take into account the ionic composition of irrigation water and the physiological requirements of plants.
