Parâmetros agronômicos de crambe cultivado no sudoeste do Paraná

Abstract

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.
