Estudio socio-económico del cultivo de maíz (Zea mayz l) en el sector Buenos Aires cantón Cumandá provincia de Chimborazo
(2016) Muyolema Loja, Pedro Iván; Valle Velástegui, Luciano
This research was carried out in the sectors of the Buenos Aires enclosure belonging to the Cumandá canton of the province of Chimborazo. The Cumandá canton is located south west of the province of Chimborazo in the western foothills of the Andes mountain range in the Republic of Ecuador. The urban center is between the coordinates 2 ° 12'28 "S and 78 ° 08'15" W. For the methodology, a sample of the total corn producers in the Buenos Aires precinct, Cumandá canton, was calculated. The interviews were carried out on site using tape recorder and field leaves, in order to know the reality of the management of this crop in the area , Then surveys were used based on the information collected to close the answers. From this information a data sheet was constructed and tabulated in the Statistics system18. It can be observed that most of the farmers are men, since they work harder physically, women intervene in planting and harvesting, farmers have primary education level dedicating themselves to growing their properties that do not exceed the hectare, do not belong to Some agricultural association. Respondents buy seed in the market of improved varieties to obtain a greater production, the most common causes that cause crop losses is mismanagement, this influences the supply of the product that can be generated, often being low prices. The majority destines their production to the market without selecting their product and for that reason the price determines it according to the competition of the merchant, some producers realize costs of production therefore the majority do not do this it reflects that the farmers are not aware of the importance of Establish how much they need to start an agricultural activity, and whether or not the process will have a profit. This explains why the study area presents a scarce study analysis, in addition it contributes unnecessary expenses like great amount of chemical fertilizers and makes an excessive use of phytosanitary products contributing to increase the costs of production. The administrative structure of the farm is 70% owned and family owned, 80% belong to no association, and 54% own land with an area of 1000 to 10,000 m2. The maize that grows the farmers is the hybrid in 62%, since 44% consider that it provides good production. The unified basic remuneration of the workers is in accordance with what is established by law, that the financing is with own resource 92% of the producers, the target market is local at 85%, 96% puts the selling price on market. 86% do not record production costs; however, 66% consider that maize production is profitable. To obtain producers who specialize in producing maize highly valued by the consumer / both local and foreign. These data show that the problem that the sector is experiencing is not from productive yields but from technical management. It is necessary to elaborate a booklet of maize crop management, to improve all aspects related to the economic partner. KEY WORDS: Market, supply and demand, natural resources, profitability, rural administration.

Identificación y revalorización de Saberes Ancestrales de técnicas agrarias en la comunidad Shuar recinto Limón, cantón Bucay
(2016) Morocho Guanuchi Dany Antonio; Jiménez Esparza, Luis
The aim of the research was to identify and revalue the ancestral knowledge of agricultural techniques in the Shuar Community Complex Lemon, Canton Bucay, by applying data collection techniques such as surveys and interviews aimed at people of different genders and age ranges; where it was identified that cocoa crops (Theobroma cacao) and banana (Musa paradisiaca L.) which are the most productive in the area, the ancestral agricultural practices have been deteriorating due to various factors, even disappear, it you can emphasize that they have been using modern technologies to pre cultural and cultural work in the mentioned crops, discarding the processes that their predecessors made. The Shuar culture is the most populous culture in Ecuador with more than 80,000 individuals distributed in the Ecuadorian Amazon and in the jungles of Peru; Here wide variety of products grown, but the crops studied in the sector are treated conventionally, where, are attacked by pests and diseases that commonly attack, which are not controlled by any product derived from ancestral knowledge regarding the community has been adopting foreign customs for the production of food. Among the practices that still made between the producers of the Shuar community are the use of the lunar cycle to cultural practices as planting, pruning and Fertilisation, the use of plant products in the medical field, and among others. Among other uses it is also used in small quantities for weed control ferments of crop residues cocoa and also as a material source of fertilizer for crops.

(2017) Parco Asitimbay, Aida Ximena; Pomboza Tamaquiza, Pedro Pablo
Palabras claves: ganadería, pastos, campesino, cambio climático, suelos. xiv SUMMARY The objective of this work was to identify the main changes in the agricultural systems: the effect of the cattle raising in the agricultural areas of Tungurahua. Two peasant communities were selected considering the proximity to the moorland and evidences of changes from agriculture to livestock. it was applied a sampling non-probabilistic, 47 polls were carried out in San Luis de Chibuleo and 30 in Atillo. In addition, 12 soil samples were analyzed: six in the community of San Luis, three of soils with grown potato (L1C1) and three of soils with pastures (L1C2); and six in the community of Atillo with the same characteristics (L2C1) and (L2C2). By means of the obtained results it is determined that the population that dedicates to these activities has an average age between 42 to 52 years. In addition, the results indicate that peasants surveyed have bovine an average of 5 heads. The main factors identified associated with the changes have been: climate change; costs of production and milk market. The cattle raising also had favorable effects such as increased fertility in pasture soils (12.67% MO and 75.67 ppm Nitrogen). Also observed that the amount of K and Mn had high values, although not significant in soils with pastures, Likewise the production of milk is helping at feeding of the peasants, because It is providing at their families around (2 L/ day) and generate a permanent income for the family (between 270 and 442 USD / month). On the other hand, the unfavorable effects like as pressure on the moorland due to animal grazing, reduction of the area of agricultural crops (potatoes) and greater food dependence of the market. The results suggest the need to incorporate agroecological practices and balance the components: livestock, agriculture and forestry of the UPAs.

The objective of this research was to evaluate the effect of the consumption of diets based on breadfruit (Artacarpus altilis) on the productive behavior of sheep. Eighteen male sheep with a mean age of 7 to 8 months and a weight of 22.23 kg were used. A completely randomized design (DCA) was used, with three treatments and six replicates, in addition to an analysis of variance and Tukey's test at 5%, with the statistical package SAS 2009. The treatments were T1: 100% alfalfa. (Witness); T2: 80% alfalfa + 20% breadfruit; T3: 60% alfalfa + 40% breadfruit. The variables evaluated were: voluntary nutrient intake (CVMS, CVMO, FVCF and FVCFN), weight gain (GP g / day) and feed conversion (CA), voluntary consumption of dry matter, organic matter and neutral detergent fiber Presented difference P = (0.0001) between treatments being the one of greater consumption T3 (1652.71; 1560.16; 872.63g) respectively. Regarding the consumption of acid detergent fiber, difference P = (0.0001) between treatments was observed, with the highest T1 value (585.77g). Regarding the weight gain presented difference P = (0.0001) between treatments obtaining the highest weight gain T3 (218.88 g / day). The feed conversion presented difference P = (0.0001) obtaining the smallest result T3 (7.55). Based on the results obtained, it is concluded that sheep fed diets containing 40% of breadfruit inclusions constitute an alternative food resource, being able to improve the productive parameters obtaining a good productive response, possibly due to the content of non-structural carbohydrates present In T3
Descripción y revalorización de los saberes ancestrales en la producción pecuaria en los recintos: Suncamal, Sacramento y La Isla, en el cantón Cumandá, provincia del Chimborazo
(2017) Caicedo Reinoso, Cristhian Rafael; Mera Andrade., Rafael
The research was carried out in the Sacramento, Suncamal and La Cumandá cantons, in the province of Chimborazo, with the objective of gathering information to know the ancestral practices of poultry, pork and cattle producers to rescue and revalue the ancestral knowledge that are kept in the livestock work of the mentioned places. The use of the ancestral knowledge and the application of the same in the livestock production, referring to the development of a pig, poultry or livestock farm, we can find some advantages, since it becomes a small family activity of backyard agriculture what the Unite more or one way for coexistence and contact with nature, and in this way to achieve higher yields with respect to profits and economic activity, in this way costs are cheaper since agrochemical or chemical inputs are not applied. Make the production system more expensive, which leads to sustainable production. The results obtained in the research made it possible to determine that ancestral knowledge should be revalued among the producers through practical workshops in order to disseminate how they work with the selected animals. For the selection of the animals take into account the size, weight, in the construction of chancheras, nests and corrals use materials of the area as bamboo cane, planks, leaves of cade, straw dry banana leaves, sawdust and through the use they use , Cooked Chinese potato, orito, tender pastures, kitchen waste. In order to combat diseases, they use plum buds for diarrhea, garlic, rue for pneumonia, for labor facilities use sawdust and in the process of laboring, the intervention and manipulation of man, to prevent diseases and disinfection of farms use incense and burning of Plants, for castration use knife and for healing use lemon, urine. KEY WORDS: Ancestral knowledge, livestock, Pigs, Poultry, Cattle, interviews, surveys.
