Metodologia para estimar a estabilidade do conjunto muda x substrato de cafeeiro A methodology to evaluate the stability of coffee seedling
A utilização de substrato em tubetes para a formação de mudas de café aumentou em substituição à mistura de solo argiloso com resíduo orgânico, resistente à deformação da muda no plantio, devido à coesão e aderência às raízes. Por sua vez, o substrato em tubetes esboroa com facilidade, em razão da g...

520 | |a A utilização de substrato em tubetes para a formação de mudas de café aumentou em substituição à mistura de solo argiloso com resíduo orgânico, resistente à deformação da muda no plantio, devido à coesão e aderência às raízes. Por sua vez, o substrato em tubetes esboroa com facilidade, em razão da granulometria do material. Do exposto, avaliou-se uma metodologia para estimar a estabilidade ao manuseio do conjunto muda x substrato, com base na variação granulométrica (G1: 30,86 %; G2: 62,26% e G3: 49,83% de partículas nas peneiras 0,50 a 0,05mm) e do volume de material (V1: 50, V2: 120 e V3: 200cm³), em mudas de café Catuaí Vermelho IAC 144 com quatro pares de folhas. A estabilidade do conjunto muda x substrato foi estimada pela quantidade de substrato desagregado e partes de raízes, após submetê-lo a cinco ciclos de 60 segundos de rotação (1.750rpm) em mesa vibratória. A estabilidade foi maior nos tubetes de 50 e 120cm³ de substrato. A redução parcial da granulometria (50% substrato na granulometria original e 50% substrato moído) aumentou a aderência das partículas às raízes e a estabilidade do conjunto nos recipientes menores.<br<The objectives of this research are the evaluation of substrate volume and granulometer influence - used in production of coffee seedlings in plastic tubes - on coffee plants growth, the time of seedlings development and also seedling-substrate handling stability. The investigation was carried out in a nursery at Coffee Experimental Center of IAC, SP, Brazil, with the cultivar Catuaí Vermelho IAC 144 (Coffea arabica L.). Nine treatments were tested with four replicates and the experimental design used was randomized blocks with 3x3 factorial composed by three substrate volumes (V1: 50, V2: 120 and V3: 200cm³) and three granulometer substrate levels (G1: 30.86%, G2: 62.26% and G3: 49.83% of particles in sieves 0.50 to 0.05mm). The stability of seedlings to handle was evaluated using a vibratory table, with basis of amount of crumbling material (substrate and roots). The joint was submitted to rotation during 60 seconds, repeated five times (5 cycles). The end of each cycle the unfastened material was collected and definitive to disaggregated mass. The stability of joint seedling-substrate varied with the size of container, bigger in tubetes with 50cm³ and 120cm³ of substrate. The partial reduction of granulometry (50% of substrate on original granulometer and 50% of crushed substrate) increased the adhesion of particles with roots and, the stability of joint. | ||

The investigation was carried out in a nursery at Coffee Experimental Center of IAC, SP, Brazil, with the cultivar Catuaí Vermelho IAC 144 (Coffea arabica L.). Nine treatments were tested with four replicates and the experimental design used was randomized blocks with 3x3 factorial composed by three substrate volumes (V1: 50, V2: 120 and V3: 200cm³) and three granulometer substrate levels (G1: 30.86%, G2: 62.26% and G3: 49.83% of particles in sieves 0.50 to 0.05mm). The stability of seedlings to handle was evaluated using a vibratory table, with basis of amount of crumbling material (substrate and roots). The joint was submitted to rotation during 60 seconds, repeated five times (5 cycles). The end of each cycle the unfastened material was collected and definitive to disaggregated mass. The stability of joint seedling-substrate varied with the size of container, bigger in tubetes with 50cm³ and 120cm³ of substrate. The partial reduction of granulometry (50% of substrate on original granulometer and 50% of crushed substrate) increased the adhesion of particles with roots and, the stability of joint.

Metodologia para estimar a estabilidade do conjunto muda x substrato de cafeeiro A methodology to evaluate the stability of coffee seedling |
abstract |
A utilização de substrato em tubetes para a formação de mudas de café aumentou em substituição à mistura de solo argiloso com resíduo orgânico, resistente à deformação da muda no plantio, devido à coesão e aderência às raízes. Por sua vez, o substrato em tubetes esboroa com facilidade, em razão da granulometria do material. Do exposto, avaliou-se uma metodologia para estimar a estabilidade ao manuseio do conjunto muda x substrato, com base na variação granulométrica (G1: 30,86 %; G2: 62,26% e G3: 49,83% de partículas nas peneiras 0,50 a 0,05mm) e do volume de material (V1: 50, V2: 120 e V3: 200cm³), em mudas de café Catuaí Vermelho IAC 144 com quatro pares de folhas. A estabilidade do conjunto muda x substrato foi estimada pela quantidade de substrato desagregado e partes de raízes, após submetê-lo a cinco ciclos de 60 segundos de rotação (1.750rpm) em mesa vibratória. A estabilidade foi maior nos tubetes de 50 e 120cm³ de substrato. A redução parcial da granulometria (50% substrato na granulometria original e 50% substrato moído) aumentou a aderência das partículas às raízes e a estabilidade do conjunto nos recipientes menores.<br<The objectives of this research are the evaluation of substrate volume and granulometer influence - used in production of coffee seedlings in plastic tubes - on coffee plants growth, the time of seedlings development and also seedling-substrate handling stability. The investigation was carried out in a nursery at Coffee Experimental Center of IAC, SP, Brazil, with the cultivar Catuaí Vermelho IAC 144 (Coffea arabica L.). Nine treatments were tested with four replicates and the experimental design used was randomized blocks with 3x3 factorial composed by three substrate volumes (V1: 50, V2: 120 and V3: 200cm³) and three granulometer substrate levels (G1: 30.86%, G2: 62.26% and G3: 49.83% of particles in sieves 0.50 to 0.05mm). The stability of seedlings to handle was evaluated using a vibratory table, with basis of amount of crumbling material (substrate and roots). The joint was submitted to rotation during 60 seconds, repeated five times (5 cycles). The end of each cycle the unfastened material was collected and definitive to disaggregated mass. The stability of joint seedling-substrate varied with the size of container, bigger in tubetes with 50cm³ and 120cm³ of substrate. The partial reduction of granulometry (50% of substrate on original granulometer and 50% of crushed substrate) increased the adhesion of particles with roots and, the stability of joint. |

Por sua vez, o substrato em tubetes esboroa com facilidade, em razão da granulometria do material. Do exposto, avaliou-se uma metodologia para estimar a estabilidade ao manuseio do conjunto muda x substrato, com base na variação granulométrica (G1: 30,86 %; G2: 62,26% e G3: 49,83% de partículas nas peneiras 0,50 a 0,05mm) e do volume de material (V1: 50, V2: 120 e V3: 200cm³), em mudas de café Catuaí Vermelho IAC 144 com quatro pares de folhas. A estabilidade do conjunto muda x substrato foi estimada pela quantidade de substrato desagregado e partes de raízes, após submetê-lo a cinco ciclos de 60 segundos de rotação (1.750rpm) em mesa vibratória. A estabilidade foi maior nos tubetes de 50 e 120cm³ de substrato. A redução parcial da granulometria (50% substrato na granulometria original e 50% substrato moído) aumentou a aderência das partículas às raízes e a estabilidade do conjunto nos recipientes menores.<br<The objectives of this research are the evaluation of substrate volume and granulometer influence - used in production of coffee seedlings in plastic tubes - on coffee plants growth, the time of seedlings development and also seedling-substrate handling stability. The investigation was carried out in a nursery at Coffee Experimental Center of IAC, SP, Brazil, with the cultivar Catuaí Vermelho IAC 144 (Coffea arabica L.). Nine treatments were tested with four replicates and the experimental design used was randomized blocks with 3x3 factorial composed by three substrate volumes (V1: 50, V2: 120 and V3: 200cm³) and three granulometer substrate levels (G1: 30.86%, G2: 62.26% and G3: 49.83% of particles in sieves 0.50 to 0.05mm). The stability of seedlings to handle was evaluated using a vibratory table, with basis of amount of crumbling material (substrate and roots). The joint was submitted to rotation during 60 seconds, repeated five times (5 cycles). The end of each cycle the unfastened material was collected and definitive to disaggregated mass. The stability of joint seedling-substrate varied with the size of container, bigger in tubetes with 50cm³ and 120cm³ of substrate. The partial reduction of granulometry (50% of substrate on original granulometer and 50% of crushed substrate) increased the adhesion of particles with roots and, the stability of joint.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Coffea arabica L.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield
