“…In both cases, the lowest concentrations were found in fruits from mineral fertilised plants (Table ). This observation does not find support in the results of Polat and co‐workers, who found no significant difference in soluble sugar concentrations of tomato fruits due to mineral or organic soil fertilisation, but is nonetheless of potential interest considering the importance of this parameter for the organoleptic quality of tomato.…”

“…O uso agrícola de esgotos e biossólidos (lodo originado em estação de tratamento de esgoto sanitário, que passou por tratamento biológico) cresceram, acentuadamente, em todo o mundo, particularmente em regiões áridas e semiáridas de países em desenvolvimento, como resposta à necessidade de aumentar a produção agrícola, principalmente de alimentos, sem aplicação de fertilizantes sintéticos; então vale a ressalva de que as águas residuárias, assim como o lôdo de esgoto não são considerada fertilizante químico (Polat et al, 2010). O efluente tratado, quando utilizado como biofertilizante, possui notadamente valorização econômica; além de benefícios ambientais, pois a prática de reúso remove parcial ou totalmente o teor de nutrientes contido nos efluentes como, principalmente nitrogênio e fósforo, antes do seu despejo nos corpos d'água, impedindo a eutrofização dos mananciais.…”

“…Titratable acidity (TA, %) of tomato juice was measured using 10 ml of filtrate juice and supplied for titration using 0.1 N NaOH until pH 8.2, and expressed as citric acid percentage (Turhan & Seniz, 2009). The pH of tomato fruit juice was determined in a 50 ml filtrate juice attained from a mixture of 10 g of fruits flesh tissues blended in 100 ml of deionized water (Polat et al, 2010).…”

The effects of different agricultural crop waste composts as organic fertilizer on the growth, leaf chlorophyll content and mineral concentrations, fruit characteristics, yield, and fruit quality aspects of tomato were assessed. The composted crop waste types used were mixture of date palm, olive, and maize (1:1:1) supplemented with 5% (C2), 10% (C3), 20% (C4), and 40% (C5) of sheep manure as well as the active NPK mineral fertilizer (C1) as a check treatment. Results of present study revealed that tomato plants grown in sandy soil amended by combination of compost mixture and 40% sheep manure (C5) have highest plant height and leaf chlorophyll content as compared to the plants grown in other combinations. Further highest concentration of nitrogen (N), phosphorus (P), potassium (K), Ferrous (Fe), Zink (Zn) and manganese (Mn) along with fruit yield, and fruit quality were also reported superior in the plant grown in same combination. The percentage increase in the total yield of plants fertilized with C5 was 65.71-65.83% higher than that of plants fertilized with the compost + NPK (C1). Tomato plants grown in plots amended with compost type C5 had highest shoot dry mass, fruit length, fruit diameter, and fruit juice percentage than plants grown in other treatments. On the other hand, tomato plants under C1 treatment had higher titratable acidity and pH of fruit juice as compared to plants grown

“…Moreover, studies on different crops indicate a decline in yields when switching in OA. Examples include: lettuce (Polat et al, 2008), wheat (Annicchiarico et al, 2010;Kitchen et al, 2003), cauliflowers, onions (Dresbøll et al, 2008), cereal and potato (Mäder et al, 2002), and sweet corn (Dufault et al, 2008). Therefore, the debate on OA and its productivity is still far from getting proven.…”

While much has been published on the advantages of organic agriculture, less has addressed its potentials and challenges to fight undernourishment in developing countries. This article aims at reviewing the main potentials and challenges of this approach when dealing with "undernourishment" as a multi-faceted concept in developing countries. Accordingly, two main issues of the concept which are "food security" and "food safety" are discussed in the context of both developed and developing countries to understand their different food policies' priorities. Next, the main potentials, challenges and tradeoffs of the organic approach are scrutinized to understand whether the approach is capable to provide a secure or safe food production system and therefore to understand whether it can meet the food policies' priorities in developing countries. With respect to food security, the article concludes that conventional and biotechnological approaches still appear to produce higher yields though considering many advantages of organic agriculture, it could, in long run, be more conducive than now to meet food security. Hence, we still need both conventional and 1 Corresponding author. Email: hossein.azadi@ugent.be, Tel. +32 (0)9 264 46 95.

Accordingly, the article emphasizes on providing farmers in developing countries with the possibility of implementing different approaches. Therefore, policy makers should be aware of a realistic and gradual transition from the other approaches to the organic that should be projected only in "long run", and after conducting a series of risk assessment studies on the bases of both 'crop-case" and "region-case".

“…In many of the stable agricultural systems and especially bio-agriculture, organic fertilizers are being used in order to improve the soil conditions and productivity in addition to preventing and controlling herbal diseases and pests (Barker & Bryson, 2006). In an experiment about qualitative criteria to produce organic and common tomato in Turkey conditions, Polat et al (2010) studied and reported that the maximum yield of tomato in the first year could result in 77940 kg/ha by using a combination of 50 tons of cow manure, 1.48 kg/ha ormin-k organic acids, 3.2 ton/ha bone powder and 30 lit/ha Humex. In the second year, the tomato yield by the same treatment was about 92000 kg/ha.…”

An experiment was conducted in the form of split-plot and random complete blocks with 3 repetitions in a greenhouse in Jiroft city of Kerman province, southeastern Iran, during 2011-2012 crop year, with the main aim to study how enriched organic fertilizer (chicken manure) and spraying methanol affects the quantity and quality of the yielding in Falcato tomato. Methanol and the enriched chicken manure as the two main and subordinate factors were studied in 4 levels (0, 20, 30, and 40 percentage of the volume) and (0, 500, 1500, and 2500 kg/ha). The results showed that the interaction of the two factors on the number of fruits per plant, the mean weight of fruit (p ≤ 0.05), and the stem diameter (p ≤ 0.01) was significant. Methanol 30% caused a 28% increase in yield, compared to the control plant. Adding 2500 kg/ha chicken manure resulted in 31% increase in the yield in contrast to the control plant. Mean weight of a fruit in 40% methanol and 2500 kg/ha chicken manure treatment was 145 g. Finally, having evaluated all aspects and factors in this study, methanol 30% solution and 2500 kg/ha chicken manure were recommended for Falcato tomato in greenhouses of Jiroft city.
