El abuso de tecnologías en la agricultura convencional (fertilizantes químicos, herbicidas, insecticidas, fungicidas), ha provocado daños en el medio ambiente y los recursos naturales, generando crisis ecológica y social, afectando en mayor medida a los pequeños agricultores. El uso de fertilizantes sintéticos en la agricultura ha sido la fuente principal de nutrientes para las plantas, sin embargo es importante buscar alternativas más sustentables en la nutrición de cultivos. Una opción viable son los biofertilizantes. El presente trabajo se realizó en el municipio de San Felipe Teotlalcingo, estado de Puebla, donde se evaluó los rendimientos y costos de producción de los biofertilizantes de preparación local, aplicados al cultivo de maíz, así como los... |

Among several alternative agricultural systems have been developed, organic agriculture has deserved increasing interest from. The objective of this paper was comparing both organic (OS) and conventional (CS) tomato cropping systems for varieties Débora and Santa Clara, through an interdisciplinary study. The experiment was set up in a randomized blocks design with six replicates, in a dystrophic Ultisol plots measuring 25 ´ 17 m. Cropping procedures followed by either local conventional or organic growers practices recommendations. Fertilization in the OS was done with organic compost, single superphosphate, dolomitic limes (5L, 60 g, and 60 g per pit), and sprayed twice a week with biofertilizer. Fertilization in the CS was done with 200 g 4-14-8 (NPK)... |

Since the onset of the commercial application of soilless culture, this production approach has evoluted at a fast pace, gaining popularity among growers throughout the world. As a result, a lot of information has been developed by growers, advisors, researchers, and suppliers of equipment and substrate. This study aimed to determine the cost and return of soilless greenhouse cucumber (Cucumis sativus L.) production and to prepare a sample budget for growers. Soilless cultivation is an alternative production method for Turkish growers and it is being practised on a commercial basis on 180 ha. Cost and return budgets can be useful for growers because they allows growers to compare total production cost and revenue varying grower type, production time,... |

Abstract This research aimed to generate a soil quality index which have allowed to compare the effect of conventional and semi-ecological plantain farming systems. For its construction, we considered biometric data of near-to-harvest plants, physical, chemical and biological indicators which were evaluated using a principal components analysis; the weight of each indicator was calculated, and so were the response curves, establishing a minimum set of data which includes: sand percentage, sheet of water, pH, Nitrogen, organic carbon percentage, potassium, biodiversity conservation and microbial respiration, respectively. In fact, this index was validated in areas cultivated with plantain cv. Dominic Harton in farms located in the same taxonomic unit in... |
