The crambe (Crambe abyssinica) presents itself as a full potential for this end and
also it’s a great alternative to the second harvest, the fall/winter´s culture and crop
rotations. Crambe shows many good characteristics that are very interesting for the
producer, among them are: high concentration of fat in the seed, low production cost,
high tolerance to hydric stress, simplicity and precocity. The main objective was to
define the spacing and density for the Southwest region of Paraná, and also
determine the plantation period as well it´s effects over the quality of the seeds,
furthermore the determination of the hydric consumption and culture rate. Four other
experiments were conducted at Universidade Tecnológica Federal do Paraná –
Campus Dois Vizinhos, in the years 2012 and 2013, seeking to analyze the effects in
the plantation period, spacing, density, water consumption and the physiologic
analysis of the produced seeds. The planting occurred between March 28th until
June 8th each one being planted every 15 days. The spacing were from 17 and 51
cm. and densities of 60, 80, 100, 120 and 140 seeds per m². The analysis of the
seed consists in: Germination, index of germination speed, length of the seedlings
and dry matter of the seedlings. The best period for both of planting as quality of the
production itself was in the second week of March, the spaces did not interfere and
the best densities are 100 to 140 seeds per m². The Kc was 0,64 until the
blossoming, 0,84 until the fructification and 0,79 until ripeness. |
