Evaluation of seed yield and oil contents in four materials cpmmunis Ricinus communis L. Roberto Antonio Cabrales R. Four castor materials were evaluated in in the middle region of Valle del Sinu, Colombia. The variables were phenological development, plant height, seed production and oil yield, in order to determine the best material for commercial purposes.
All materials reported high yields of oil seeds and highlighting the commercial genotype Nordestina BRS, 2.
Planting distances riciuns 1. These variables were significantly different between population densities, which shows that the higher the plant height, lower productivity. The planting distance of 2.
The oil quality parameters were ricinsu using free fatty acid value, iodine, acidity index, saponification, refraction and specific gravity, found that planting distance does not affect the quality of oil.
Las distancias de siembra fueron 1,5 x 1,5 m y 2,0 x 2,0 m, con densidades de 6. Estas variables fueron significativamente diferentes entre densidades poblacionales, lo cual muestra que, a mayor altura de planta menor productividad.
The castor bean Ricinus communis L. Its great feature is the potential for the production of industrial oils, which have various applications in fields such as medicine, cosmetics and more recently, the energy in the production of biodiesel that aims to reduce consumption of petroleum and reduce environmental pollution, making the species in an operational alternative for men Gutierrez et al.
In Colombia, the castor is a promising species due to the great adaptability in most of its thermal levels, achieving comjunis yields of seed yield and quality of their oils, allowing its application in various industrial sectors Delgado, In some Ridinus regions, such as Antioquia, Caldas, Santander and Tolima, were evaluated on a small scale some native materials using pattern matching as Brazilian and Ecuatorian genotypes.
These in order to improve farming techniques and to obtain high quality oils and yields, which determine the viability of castor crop projection on a large scale for industrial production of the oils in these areas. As for the quality of castor oil, Bailey et al.
Castor oil is distinguished from others by its high rate of acetyl or hydroxyl, and other oils with similar iodine because of its high density.
Unlike other oils, is miscible in all proportions with alcohol, ricinuss at room temperature is only slightly soluble in petroleum ether Bailey, Currently, the department of Cordoba, where the castor grows wild in most parts of the territory, reaching heights up to 4 m and there is no knowledge higuetilla the productive performance in terms of seeds and oils of native and imported materials that could be grown in warm weather conditions and silty clay soils that characterize this region IGAC, Therefore, this study aims at evaluation of four materials of R.
The area is characterized by a soil usually composed of fine materials silt, clay and fine sandless permeable, allowing water logging in rainy and dry periods cracking IGAC, The four materials used in this research Castor were three natives: In the test group, the materials were evaluated during a period of 8 months.

Planting was done the first week of February summer time and application of sprinkler irrigation. We used a split-plot experimental design, arranged at random with three repetitions. The subplots were in two-plant spacing of 1. The total experimental units were 12 plots and 24 subplots for a total area of 1, m 2 per experimental sampling unit and as all the plants in each subplot including plants border.
The variables evaluated were: Oil extraction The seeds collected from each material were dried initially grown under conditions suggested by Madrid et al. This process prior to oil extraction, was required to determine the water content of castor seeds for experimental material, in plots and subplots A and B.
Subsequently, each subplot was taken by three 3 samples of 10 g. Dry seed, crushed shell and for determining the oil content by ether extraction method AOAC, using benzine as extractant Tab. Thus extractions were performed 24 total, 6 per material and 4 plot subplot. Evaluation of oil quality. The seedling emergence was between 7 and 9 days after sowing, highlighting the potential for germination earliness and Nordestina BRS genotype, this is most certainly improved the quality of the seed.
In other places where the material is grown Nordestina BRS, the onset of flowering was 80 days Camacho et al. The duration of the flowering ricinsu of the four materials averaged 82 days, however, there was contrast between the times of flowering of native materials with the commercial, as this was more delayed days, which may be favorable to obtain high yields of seed and oil yield. The harvest of native materials initiated earlier days on average than the hiugerilla Nordestina BRS dayspresenting the material Monteria earlier age days.
Evaluation of seed yield and oil contents in four materials of Ricinus communis L.
Normally the seed crop is considered precocious if it started at days and days late MAG, Furthermore, the completion of the harvest which determines the cycle of the crop of castor, did not show marked differences between native materials days on averagewhich proved to be more precocious than the commercial genotype statistically significant difference, culminating the growth cycle in days. The production time was considered from the beginning of flowering until the end of the harvest.
As shown in height of the plant parameter and seed production, genotypes, no statistically significant differences, while the oil yield significant differences between native and commercial materials. Plant height of the four hlguerilla tested showed a mean of 3. The values higuerill for plant height, seed production and oil yield for each material densities subplot A: The effect of competition between plants is clearly reflected in the variable height, where taller plants presented with planting distance of 1.
Regarding seed production, the highest values were obtained with the material and within the Nordestina with the greatest distance Among the native materials, it is highlighted Monteria production of 10 kg plant-1 at planting distance 1.
It is important to note that seed production was higher at greater distances from seed, except in Monteria in which material was greater than 1. The highest values of the percentage of oil yield improved material presented in the two planting distances, values statistically higher than those obtained with native materials. Among the group of native materials are not significant differences and the highest values were obtained with the distance of 1.
By adding the above results to those obtained in the variables beginning of flowering, flowering time, start and end of crop harvest, there is the benefit to the genetic improvement of native materials, Nordestina BRS case, expressed in facilities benefit agronomic management of these cultivars as cash crops. The same comparison between native materials does not show significant differences. The results presented in Tab. It also emphasized that the results obtained in this study for the four materials evaluated in seed production and oil yield were good.
The having better commercial production Nordestina BRS genotype Through an analysis of variance shows no significant differences between the results obtained for the subplots A and B of any of the four materials, therefore studied planting distances are not a factor influencing the quality of oil. Point is very important too, that all the parameters are within the ranges of the Tab.
Although saponification is usually related to the average molecular weight of oil, this is a difficult measure accurately when defining oil. It highlights the commercial genotype for high seed production 2, The comparison between densities shows significant differences in plant height and seed production and, at higher altitudes lowers productivity but no differences in oil yield. The study highlights the planting distance of 2.
The quality of the oils is not significant differences by relating them to the variable spacing.

Meanwhile, some physicochemical properties such as acidity and saponification, show different values together for all native materials compared to commercial material Nordestina.
