“…This type of certification requires minimal bureaucratic procedures; does not entail any cost for those involved (producers, consumers, academics) and is governed by a combination of official rules and the characteristics of each region were the food is produced (Pérez Sánchez, 2015;Márquez-Hernández et al, 2010).…”

VIZCARRA BORDI, IVONVE y THOME-ORTIZ, HUMBERTO (2017). The consumer of food products in organic markets of central Mexico.British Food Journal, 119 (3) 558-574. The consumer of food products in organic markets of central Mexico Purpose -The purpose of this paper is to identify the characteristics of consumers of organic food, based on their motivations. Design/methodology/approach -A questionnaire based on the Food Choice Questionnaire was applied to a 656 consumers. A multivariate factor analysis and cluster analysis was performed to the data. Findings -Seven factors were identified: ecological concern; nutritional content; availability of natural products; sensory aspects; certifications, health and confidence; and economic aspects. Resulting clusters were named as: conscious and interested in certification; conscious with no interest in certification; opportunist in transition; unconscious opportunist. There are signs of different consumers. The consumers of these products are characterised by an interaction between hedonic and ethical motivations, where the most important motivation is environmental concern and the least important are the economic aspects.Research limitations/implications -The reduced number of alternative markets in Mexico limits the amplitude of the research. Practical implications -The work herein reported is pioneer and contributes to reduce the lack of studies on the motivations and characteristics of consumers of organic foods in Mexico. Findings may set a path for new research in other cultural contexts; as well as for more specific work in Mexico as of consumers of industrialised organic products. Social implications -Characterising consumers of organic foods will enable the development of these markets. Originality/value -Social studies of eating habits have taken place in European countries; and several works have been developed in other areas of the world to determine the way in which consumers build their preferences and food choice patterns. In Mexico, specifically in organic foods, studies have focussed in agrarian economics, but the analysis of motivations for choice has not been addressed. Therefore, it is important to research this issue given the relevance for consumers.

“…Two tomato hybrids, Big Beef and Miramar, were studied by Rodrí guez Dimas et al (2008), and some results showed that in earthworm humus growth media, the concentration of SS ranged between 4.8 to 5.3 and 4.9 to 5.3 °Brix, respectively. The range of SS determined in this experiment greatly exceeded the 4.04 °Brix reported by Márquez-Hernández et al (2008) when they used organic substrates during the production of tomato, with genotype Bosky, under greenhouse conditions. Although the SS produced by treatments T2, T3, and T4 (which included the VC) were inferior to those of the control treatment (T1), their range of results (4.27 -4.92 °Brix) can be fairly compared to the range that Diez (1995) established as optimal levels for tomato (4.4 to 5.5 °Brix).…”

Different studies have suggested that the use of vermicompost as part of the plant growth media can provide nutrients and retain moisture while promoting the development of crops. To corroborate this assumption we tested the effects of vermicompost supplementation to tomato (saladette type) under greenhouse conditions. The evaluated treatments included four mixtures (T1, T2, T3, and T4) of vermicompost and river sand, with volume ratios 0:1, 1:1, 1:2 and 1:3, respectively. Physical and chemical tests were performed in each mixture to determine nutritional elements (N, P, K, Ca, Mg, Na, Fe, Cu, Zn, Mn, organic matter, pH, texture, cationexchange capacity, electric conductivity, and apparent density) and water holding capacity. Treatment with 0:1 volume ratio (T1) was used as control, and it was fertilized with a nutrient solution [KNO 3 , Ca(NO 3 ) 2 , Mg(NO 3 ) 2 , phosphoric acid concentrate, and multi Maxiquel (Bioagro ®)]. Seeds were sown in polystyrene trays with 200 cavities, padded with peat moss; seedlings were transplanted 37 days after sowing in 20 L black plastic bags. Harvest, including up to the fifth cluster, was performed manually, when the fruits reached a pink color. The treatment effects on tomato were evaluated considering the number of fruits, number of locules, equatorial and polar diameters, pulp thickness, soluble solids, fruit weight and fruit yield. The four treatments were repeated eight times in a completely randomized design. Data were statistically analyzed by analysis of variance and means were separated by the LSD 0.05 test. Five of the variables studied -number of fruits, number of locules, soluble solids, pulp thickness, and yield-showed highly significant difference (P≤0.01) among treatments; the polar diameter showed significant differences (P≤0.05), and both equatorial diameter and weight of fruit were not significantly different among the substrates tested. The maximum yield (50.29 t•ha -1 ) was obtained in treatment T2 with a water volume of 40 L•pot-1, followed by T1 (49.93 t•ha -1 ), applying a water volume of 95.72 L•pot -1 . Derived from the results of the best treatment (T2), and under conditions described, the productivity was estimated in 30.66 kg•m -3 . Since no synthetic fertilizers were used during the crop production, the results indicate that the vermicompost was able to satisfy the nutrient demand of tomato plants and reduces the volume of water required by this crop.

“…The crops sown and the weeds that arrive by the wind settle in the little substrate and prosper thanks to the abundance of water and sunlight, some are beneficial plants. The important thing about this is that organic tomatoes are harvested that are very healthy [11]. At the level of first-order consumers, hens feed on the vegetables produced, arthropods and insects [12].…”

The study objective was to design and evaluate the agroecological system of an agricultural model with vegetable covers (Luffa cylindrica, Cyclanthera pedata and Mucuna pruriens) associated with tomato plants (Lycopersicum esculentum Mill), Rio Grande and Cherry varieties. The agroecological system is shown with its components of inputs, processes and outputs. The main entrances being solar radiation, rainwater and air as main sources for plant photosynthesis. Components of rooftop agroecosystem are soil, plants, animals and microbes, which form the food pyramid in ecological balance. Production benefits the family in terms of food safety with safe pesticide-free tomatoes. At the same time there is a plant barrier on the roofs to reduce the effects of solar radiation that favors the comfort of the family; in this way the research is framed in the nature of cities with green roofs with their multiple ecological benefits. A new tomato variety obtained by natural crossbreeding between the Cherry and Rio Grande varieties has also been obtained, with medium-sized fruits favorable to the organic tomato market, whose average equatorial diameter is 2.82 ± 0.086 cm, and the average polar diameter 2.47 ± 0.105 cm.
