    The moral fine (Chlorophora tinctoria), it is a specie of a great importance at world level from the social, cultural, economic and environmental point of view. The indiscriminate pruning and the inadequacy of sustained programs of forestation pun in risk the existence of this species and many others. One of the factors that determine the low productivity of this specie is the short viability that presents the seeds, the unfavorable environmental conditions, and the insufficient knowledge of the benefits, for what it is necessary to evaluate the sexual propagation of this specie in different bases and gibberellic acid dose in nursery stage. This investigation was carried out in the canton Echeandía to 6 km road to Guaranda to an altitude of 600 msnm osl, with a temperature average of 18o C and an annual precipitation of 2500 mm. The objectives established in this investigation were:  Determine the most excellent agronomic characteristics that present the plants in each one of the treatments.  Study the effect (answer) of the gibberellic acid on the sexual propagation of fine morals.  Determine the best type of basis to obtain the best germination percentage.  Carry out an economic analysis cost/benefit. A complete blocks design was used DBCA at random in factorial arrangement plus a sample 3x3+1 with there repetitions. The A factor corresponded to there types of bases: A1: black soil plus bark of rice, A2 black soil plus guabos soil plus bark of coffee. The factor B corresponds to three gibberellic acid dose: B1: 100 ppm, B2: 200 ppm and B3: 300 ppm of gibberellic acid, 9 treatments were obtained plus a sample with three repetitions with a total of 30 treatments. The chemical of the bases, variance analysis, test of Tukey to 5%, simple analysis of correlation and simple regression and economic analysis were made. The germination of the seed of this specie is from 80 to 100% provided you sow it on time and with an appropriate treatment. As for the control of plagues and illnesses was carried out with Lynx for the earth and the rest was controlled in a homemade way, putting in practice insecticides, fungicides and trap for insects adults were guided to the organic control, in a nursery tree is more efficient this methodology in the definitive place it become more tedious this type of controls. The results most release obtained in is investigation of agreement a the objectives were: Regarding the most excellent agronomic characteristics the treatment what presented the best results in the 70% of the variably was T6 A2B3: soil plus soil guabos a 300 ppm of gibberellic acid.

    At national level the cultivation of corn is a working source for thousands of Ecuadorian. The production of corn is carried out mainly in lands of irregular topography, where the small property prevails and in 86% the production system is the corn associated with bean of type Mixturiado, particularly in the Bolívar State. By means of studies carried out by the Department of Handling of soils and Waters (DMSA), of the INIAP Santa Catalina has been demonstrated that the nitrogen (N) you/he/she is the main restrictive element of the production and due to a low efficiency of the same one, which is leached as Nitrates, you volatiliza like Ammonium and NO2 -, giving as effect the contamination of aquifer and of the atmosphere. By means of several experiments, it was possible to determine that great part of the contamination of the environment, caused by the inorganic fertilizers and the damages that it causes on the alive beings can decrease with the use of the microbial biofertilizantes with the help of stubs of Azospirillum spp. The County Bolívar is the main producer of soft corn and being the (N) the main obstacle for a good development of the cultivation, the Program of Corn of the (INIAP), with the State University of Bolívar, they have carried out a process of oriented investigation to validate the effect of three stubs of Azospirillum spp, (stubs Bolívar, stubs Chimborazo, stubs Tungurahua) and three dose of Nitrogen in the cultivation of corn variety INIAP-111l. A design of complete blocks was used at random (DBCA) in factorial arrangement 4 x 3, for that which thought about the following objectives: i) To Validate the answer of the three stubs of Azospirillum spp, for the production of soft corn. ii) To Evaluate the answer of the three doses of N on the different components of the yield of corn INIAP 111; iii) to Carry out a budget economic analysis partially and marginal rate of return, to determine the best treatment and to transfer the technology to the farmers. A significant effect of the stubs gathered in the counties of Chimborazo, Bolívar and Tungurahua existed; being the most efficient in this investigation the Stump Chimborazo with 5.335 Kg\ha of soft corn. For the N, a lineal answer was presented, that is to say to bigger dose of N, but yield of corn. Additionally, a dependence of factors was determined among the stubs of Azospirillum spp, and the N, bony they were dependent factors. However for the area agroecológica of the Laguacoto, the best application as for net profit is the treatment: T8: C4N2 (stubs Chimborazo+ 60 Kg\ha of N). Finally this study allowed reducing the use of (N) synthetic at 60 KgN\Ha of the highest dose, what contributes to the reduction of the contamination of the environment with a production in ecological process of the dry corn, contributing to the alimentary security

    Inventario de especies arbóreas del bosque nativo San José de las Palmas, parroquia San Pablo, cantón San Miguel, provincia de Bolívar
    (Universidad Estatal de Bolívar . Facultad de Ciencias Agropecuarias . Escuela de Ingeniería Agronómica, 2013) Castillo Guizado, Orlando Javier; Monar, Nelson
    6.2. Summary A botanic study was carried out in the San José de las Palmas humid montane Andean forest (San Pablo sector, San Miguel parish, Guaranda canton, Bolivar province, Ecuador). This particular forest is spread over 34 Ha and is being highly and quickly deforested. It can be considered a good representative of all native Andean forests in Ecuador and gathers an incredible biodiversity. Consequently, we believe increasing the scientific knowledge about this habitat constitutes an essential step towards a better recognition and forest preservation. The main goals established for this study are: inventorying the tree species, characterizing and estimating the tree diversity as well as making a floristic comparison with a similar forest. Three parallel transects of 100 x 4 m and separated by 200 m in altitude were set in the forest. All trees with a DBH > 2 cm were taken into account and sampled. The taxonomic determination process took place at the ESPOCH Herbarium and the results were tabulated and analyzed using Excel. A total of 108 individuals, corresponding to 42 species and 24 angiosperm families were inventoried. Within the overall diversity we obtained a mean tree specimen with the following characteristics: a 20.73 ± 14 cm DBH, a 0.049 ± 0.08 m2 basal area, a 12.1 ± 4.75 m height, a 0.76 ± 1.52 m 3 volume and a 0.83 ± 0.44 cm bark thickness. Categorization of the trees can be summed up as 28% of dominant species (> 16 m), 26% of codominant (11-15 m), 35% of intermediates (6-10 m) and 11% of repressed species (1-5 m). Each determined species was precisely described and characterized. Of all species, 8 were highlighted as endangered according to the UICN Red List for Endangered Species. The Simpson Diversity Index was used in order to estimate the tree diversity. We obtained the very high value of 0.95 for the index, which indicates that the San José de Las Palmas forest is highly diverse. A floristic comparison was conducted between the San José de las Palmas forest and the Porvenir forest (TESIS, Melendez, V. 2010) using the Sorensen Similarity Index. A high similarity value was expected as both forests are ecologically and geographically close. Nonetheless, the SSI value obtained reached only 23%, which we assume is due to a significant difference in some environmental factors not taken into account in the study. The results obtained confirm the San José de las Palmas forest presents an outstanding phytodiversity and a high ecological value. Therefore, raising awareness among the community regarding the importance of these resources as well as taking imminent joint actions with governmental institutions are crucial so to assure the conservation of Andean montane forests

    (Universidad Estatal de Bolívar . Facultad de Ciencias Agropecuarias . Escuela de Ingeniería Agronómica, 2013) Escobar, Darwin Adolfo; Suárez Morales, Kerlin Lenin; Fierro, Sonia
    The establishment of forest plantations is a very common practice that offers benefits like to protect and to restore the fertility of the floor; it improves the climate, the cultivations, and the fauna. Independent of the origin of the plant, be to for seed or fabrics, the first days of life are critical for their survival, being necessary to use vegetable hormones that stimulate the growth and development of the organs of the plants, assuring a bigger percentage of survival and the new plants continue this way their development and acquire the strength to the being to transplant them to the definitive place. This investigation was carried out in the farm of the UEB, canton Echeandía to an altitude of 600 msnm with a half temperature of 25 oC, an annual precipitation of 2300 mm. The outlined objectives were: i) Evaluate the quality of Plantae of five forest species by means of the application of three treatments pregerminativos. ii) Determine the germination percentage in each one of the treatments pregerminativos. iii) Evaluate the morphological characteristics that it presents the forest species in each one of the treatments. A Design of Complete Blocks was used at random in factorial arrangement 5x3 with four repetitions. The Factor A it corresponded to five forest species: A1= Saman; A2= Mahogany; A3= Pechiche; A4= Guaiac and A5= Fernán Sánchez. The Factor B was three methods pregerminativos: B1= Gibberellic acid soaking 4 hours; B2= Gibberellic acid soaking 8 hours and B3= Gibberellic acid soaking 12 hours. Fifteen treatments were had. Variance analysis was made, test of Tukey to 5% to compare averages of main factors and interaction and economic analysis. The most outstanding results obtained in this investigation were: The forest species Fernán Sánchez had 98,83% of survival. The methods pregerminativos B3= Gibberellic acid soaking 12 hours with 95,05% and in the B1= Gibberellic acid soaking 4 hours they reached 94,75% of survival. The most effective treatments were the T9: Pechiche + gibberellic acid soaking 12 hours; T 3: Saman + gibberellic acid soaking 12 hours and T7: Pechiche + gibberellic acid soaking 4 hours where one had 100% of survival of plants to the 90 days. In function of the economic analysis the best net profit one had in the T9: Pechiche + gibberellic acid soaking 12 hours and T3: Saman + gibberellic acid soaking 12 hours with $. 14,60 with a RB/C 5,29 and a RI/C 4,29

    The bean cultivation is considered as a commodity and strategic for the rural development of the countries, occupying the second place at world level, for its content of proteins and hydrates of carbon, it also contributes to the nitrogen fixation biological to the soil. This research was carried out in the parish of Veintimilla of the Canton Guaranda to an altitude of 2622 mls, in soil franc and 696.31 mm of precipitation during the whole cycle of the cultivation. Eight treatments of bean were evaluated in alone crop. The seed planting was 12/19/2011, in a system of reduced farm, in rotation after corn. A design of complete blocks was used at random. They were carried out variance analysis, test of Tukey to 5%, correlation analysis and lineal regression and evaluations participatives in formation of pods and in poscosecha. The most outstanding results were for tender it was selected to the line T1; good load of pods, (big, healthy, thick and color of spotted red grain), it is tolerant to deceases. For dry grain the biggest acceptability was for the lines T6: I – 426 Canary for its yellow color of the grain, its good price in the national market, tolerant to deceases foliares; T8 for their brilliant red color, I seed thick, it forms round and of good acceptability in the market. Finally this investigation it allowed to select lines of bean superior to the control local bean Canary that is late, very aggressive for associate with corn and susceptible to the yust
