Caracterización y evaluación de ecotipos de maní criollo (Arachis hipogaea L), del flanco occidental y Valle de Casanga de la provincia de Loja

This paper Creole peanut collection, was conducted in western flank Casanga valley, and then planted in the neighborhood Rumipamba, belonging to the Canton Chaguarpamba Loja Province, in order to characterize and evaluate the ecotypes. The main objective is stated: "To contribute to the rescue of Creole peanut seeds (Arachis hypogaea L) western flank Casanga Valley, to build better production conditions." And specific: Collecting groundnut germplasm materials Creole and associated knowledge in production and use of the western flank Casanga Valley; characterize morphologically Creole peanut ecotypes collected and disseminate the results to smallholders maniseros western flank Casanga valley in the province of Loja. We performed the collection of Creole in the canton peanut avocado, Chaguarpamba Olmedo and Paltas, at altitudes of 690 m.s.n.m to 1 724 m.s.n.m, where they found 25 samples that were then planted. The trial was conducted in the neighborhood Rumipamba, located in Canton Chaguarpamba, Loja Province, has a mountainous physiography Andean type, subtropical climate, with an average temperature of 21-24 ºC, with an annual average cloudiness 70-80 %, in the rainy months and between 10-20 % in the dry months, the wind direction is from east to west, with a speed of 40 km per hour. Sowing was done in the months of August to December, in the dry season, with irrigation water. 25 treatments was used, with 4 replications, 100 units experimental plot of the distance between 0, 50 m between blocks 1 m, the area per unit experimental 4 , the area of a block is 60 * 2 (120 ).The distance between rows and between ground is 0, 40 m, the number of plants per plot were 36, per block 900, total 3 600 plants and entire test area of 660 . We conducted soil preparation, layout and placed the appropriate sign according to each treatment, and then pay with compost 7.71 kg per plot and planting was done. During assay development were measured according to variables characterizing peanut manual, published by the IBPGR; also performed cultural work and phytosanitary controls With regard to pests and diseases, the damage caused by these were found within economic thresholds. Characterization results were tabulated, statistically analyzed and presented in tables and figures showing the 5% significance between treatment. The best treatments for intersections are: T 6.OOL m.blanco 1 866,319 kg / ha, T 8.CHCHEG m. black 1 916.665 kg / ha, because they are the highest in performance and in the variable of days to flower at 36 days are the most precocious.
