Abstract Tomato fruits are perishable products that require treatments such as coating films to extend their shelf life. Because of this and to avoid use of synthetic chemicals to prevent physical deterioration during postharvest, we evaluated the effects of an edible coating polymer latex poly (vinyl acetate-co-vinyl alcohol), P (VAc-co-VA), at three concentrations (0, 50 and 100%) in tomato fruits. The trial was conducted at room temperature conditions (31 ± 4 °C; with RH of 30 ± 5%) and temperature-controlled (12 ± 1 °C; with RH of 75 ± 5%). Fruits coated with P (VAc-co-VA) at 100 and 50% showed significantly… More >

Abstract The response of cherry tomato to biofertilization with beneficial microorganisms was evaluated under shadehouse conditions. Seeds were inoculated and/or co-inoculated with Azospirillum brasilense (Az) and/or Glomus intraradices (Gi). Thereafter, seedlings of six treatments received two applications of a suspension containing Az + Gi at 15 and 30 days after the transplant, and were compared against a non-inoculated treatment which only received conventional inorganic fertilization. Seed co-inoculation with A. brasilense and G. intraradices plus two applications of Az + Gi at 15 and 30 days after transplant increased on average 6% plant height, 11% leaf area, 10.5% dry biomass and 16%… More >

Abstract In plants, compensatory growth takes place when the positive effects of defoliation compensate the negative ones, and defoliated plants show a similar or increased production in relation to non-defoliated plants. Our objective was to evaluate the ability to compensate defoliation of Poa spiciformis, a forage perennial tussock grass in southern Patagonia (Argentina). The experiment was performed in potted plants that grew under controlled conditions of watering and fertilization. Three defoliation frequencies were imposed (zero, three or five) using 20-25 day intervals among them. Harvest intensity was always equivalent to 50% of the aerial biomass. Fifteen plants were sampled per treatment,… More >

Abstract We evaluated the possibility of making jam (product A) and simile sweet potato jam (product B) from the edible pulp of the fruits of Geoffroea decorticans. The first step was the chemical characterization of the flour (pulp) highlighting their carbohydrate (85.6%), protein (9.4%) and mineral (4.2%) concentrations. Sucrose (29.5%), glucose (3.80%) and fructose (5.30%) levels were quantified using gas chromatography. Contents of protein (5.7%), minerals (3.4%), dietary fiber (0.97%), sucrose (46.8%), glucose (1.9%) and fructose (2.4%) were very good in jam. The simile sweet potato jam had low calories (140 Kcal/100g) and provided protein (4.6%). During the 12-month-storage period, the… More >

Abstract The aim of this study was to determine the effect of a granular or liquid fertilizer on the temporal variation of phytoplankton. Enrichment of the pond water with nitrogen and phosphorus resulted in an increased gross photosynthesis and biomass of the dominant algal species. Nutrient concentrations and dilution rates can determine the temporal variation in phytoplankton abundance and primary production. The variation may be largely maintained by nutrient regeneration or turnover from different forms. More >

Abstract The aim of this study was to assess the land equivalent ratio, biomass, grain yield and ethereal extract of Helianthus annuus in monoculture and associated with Pisum sativum in function of stabilized urea (0, 40, 80 kg N/ha) in El Cerrillo, México. It was also estimated pod yield obtained by P. sativum as a pure stand and associated with H. annuus. The six treatments (in each experiment) were evaluated in a 2 × 3 factorial experiment in a randomized complete block design with four replications. When F values were significant, the honestly significant difference test at the 5% level of… More >

Abstract Seed production requires not only the application of appropriate techniques but also a good knowledge and planning aspects of agricultural production that allow an effective use of the staff and available production facilities. The advantage in using biofertilizers in agriculture is the reduction in production costs. This is because less chemical fertilizers are needed, and in turn this implies a reduction in input costs. Therefore, the objective of this study was to determine the best combination of chemical and organic fertilization for seed production on triticale (X Triticum secale Wittmack). The study was conducted at the Instituto Tecnológico de Roque,… More >

Abstract The production and quality of garlic (Allium sativum L.) depend on agronomics management, physiological and sanitary characteristics of bulbs or bulbils used at sowing, and economic resources. The objective of this assay was to evaluate the effects of garlic bulb and bulbil sizes, and of plant density, on seedling emergence, and garlic bulb yield and quality cv. Taiwan. The garlic bulbs and bulbils classified and selected by size were made from Extra Flor, Gigante and Jumbo garlic bulbs. They were sown at three plant densities (333000, 285710 and 250000 plants/ha) in a split plot experimental design. During garlic growth, the… More >

Abstract Public demand for healthier foods and more sustainable food systems in the U.S. has triggered market prices and production of organic alternatives of major crops such as corn (Zea mays L.). Two cover crops and their interactions with tillage systems, N sources and N rates were studied to evaluate the possibility of using these agronomic practices to facilitate growing corn under organic management in Kentucky. A split-split plot design in a RCBD with four replications was evaluated in three environments (SP08, UKR08, UKR09). The main plot treatments were cover crops [hairy vetch, HV (Vicia villosa Roth) and rye (Secale cereale… More >

Abstract The aim of this study was to evaluate grain yield (RG) stability of some commercial wheat varieties, and to assess the stability of other parameters which are not typically measured for grain release purposes: performance of straw (RP), weight per hectoliter (PH), white belly (PB), harvest index (IC), grain protein (PG) and gluten strength (W). The evaluation was performed with the wheat varieties Cachanilla F-2000 (C), Yécora F-70 (Y) and Triguenio F-00 (TR), in El Valle de Mexicali, Baja California under four test environments, with the application of the Eberhart and Russell model. The study was developed during the 2010-2012… More >
