Universidad Eafit, Medellin Colombiap. Higuerilla BRS Nordestina. These variables were significantly different between population densities, which shows that the higher the plant height, lower productivity.

Rocinus bioenergy feedstocks are crop residues while, forest and cellulosic biomass are feasible feedstocks to produce biofuels which rural population already use directly, mainly for heating and cooking; furthermore those low cost and readily available biofuels contribute to alleviate the energy shortage hifuerilla rural level for isolated communities Borjesson, ; Girard and Fallot, The water tension in the substrate also influenced the castor bean plant stem diameter SD growth curve Figure 1C.

All materials reported high yields of oil seeds and highlighting the commercial genotype Nordestina BRS, 2.

Ricinus communis

The variability has been increased by breeders who have selected a range of cultivars for leaf and flower colours, and for oil production. For the genus of lice, see Ricinus insect.

Parameters b and c of the castor bean plant height growth curve were not influenced by the increase in water tension in the substrate, whereas, parameter a was affected Table 1.

Castor seeds have been found in Egyptian tombs dating back to BC; the slow burning oil was used mostly to fuel lamps. Borjesson Energy higusrilla of biomass production and transportationBiomass and Bioenergy Oil from castor oil plant.

To monitor the soil water tension in the substrate, a tensiometer with mechanic vacuum gauge was installed in each pot higuuerilla 0. Thus, the castor bean plant transpiration rate increases when soil water tension is reduced, and also when LA and incidence of solar radiation are increased, being, therefore, a result of the interaction soil-plant-atmosphere system.


This aided to select a more feasible and efficient energy source for a particular process in the productive stage. T1, soil water tension in the substrate maintained at 0.

Plants with the dark leaves can be found growing next to those with green leaves, so there is yiguerilla likely only a single gene controlling the production of the pigment in some varieties. The having better commercial production Nordestina BRS genotype The growth curves for LA, plant height and stem diameter were adjusted based on the following logistic model: Normally the seed crop is considered precocious if it started at days and days late MAG, The latter by increasing effective usage and reduce wastes.

Dissidents and regime opponents were forced to ingest the oil in large amounts, triggering severe diarrhea and dehydrationwhich could ultimately cause death. The common name “castor oil” probably comes from its use as a replacement for castoreuma perfume base made from the dried perineal glands of the beaver castor in Latin.

Parameters a and b of stem diameter growth curve were not statistically different between T2 and T3, but they were significantly lower than those in T1 Table 1. Throughout the analysis of energy flows, it can be established the energy flows, the identification of individual and entire energy demand and determinate the whole energy performance, which is revealed by means of the net gain and also by the ratio of energy made available over the invested energy.

Solar radiation data was obtained from Embrapa weather station. 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. Figure 1 shows that castor oil plants seeds have the largest concentration of energy. The production time was considered from the beginning of flowering until the end of the harvest.

The Bodo tribals of Bodoland in Assam, India, use the leaves of this plant to feed and rear the larvae of muga and endi silkworms.


Also, biomass of whole castor oil plant except seeds generates twice energy than oil from seeds, so whole crop harvesting has to be promoted. In addition to the high potential of castor bean for oil production, which has a wide range of applications in the chemical and pharmaceutical industries, and the possibility of its usage as raw material for biofuel production Savy Filho,castor bean by-products can also be used.

Whole castor oil plant.

Introduction Rural farming provides food, fiber and raw matter for sustaining human beings. Main is constantly interacting with energy flows, thus the calculation of energy balances shoul be a priority when efficiency and profitability are the main concern.

Introduction The castor bean Ricinus communis L. The variables were phenological development, plant height, seed production and oil yield, in order to determine higuegilla best material for higueeilla purposes. Noria San Marcos, Zac. Reichardt Energy flow in castor bean Ricinus communis L. Ricinus communis can vary greatly in its growth habit and appearance. The variables evaluated were: As for the quality of castor oil, Bailey et al. Ricin has been investigated for its potential use as an insecticide.

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 same comparison between native materials does not show significant differences. Plant of the Week: The leaves of some other varieties are green practically from the start, whereas in yet others a pigment masks the green color of all the chlorophyll -bearing parts, leaves, stems and young fruit, so that they remain a dramatic purple-to-reddish-brown throughout the life of the plant.

This feature makes energy to be straightforwardly consumed by thirsty, marginal and disperse rural communities.
