Resumo: | The technique of irrigation and use of soil mulch can cause changes in the variables of crop production. Thus aimed to evaluate the effects of different blades irrigation applied through drip method and use of straw elephant grass (Pennisetum purpureum Schum. cv. Cameron) as mulch on the soil variables of production of onion bulbs (Allium cepa L.) and its water use efficiency under agroecological farming. The experiment was conducted from May to September 2012 in the Integrated system Agroecological Production, located between the coordinates 22 ? 45 'S and 43 ? 41' W, in the municipality of Serop?dica-RJ. The experimental design was a randomized complete blocks with split plots, with 10 treatments and 7 replications, characterized by the presence (CC) and absence straw how mulch soil (SC) and five blades irrigation caracterized for percentages of the crop evapotranspiration (ETc) 22, 45, 75 and 100%, termed blades L1, L2, L3 and L4, respectively, and the blade L0, characterized by the absence of irrigation. The variables evaluated were the total productivity of bulbs (PTB), Average fresh bulb weight (MMFB), dry matter content of the bulbs (TMSB), diameter bulbs (DMB), which are divided into 7 classes in diameter, total soluble solids content (TSST) and the efficiency of water use (EUA). Data were tabulated and subjected to analysis of variance and means were assessed with the regression technique to the blade factor for irrigation, and of the f test for comparison of means with regard to the coverage factor of the soil. The blades irrigation factor significantly affected the variables PTB, MMFB and DMB ranging, respectively, from 11.4 to 52.1 t ha-1, 28.6 to 130.3 g and 3 to 5 mm, and in average 98.6% of their variations were explained by the polynomial regression second-order. The blade also influenced significantly in the polynomial regression second-order (condition SC) the EUA, which ranged from 107.08 to 140.67 kg ha-1 mm-1 and in the linear regression with values ranging from 148.35 to 218.10 kg ha-1 mm-1 (CC condition). Unlike, the applied blade did not significantly affect the levels of total soluble solids, ranging from 9.9 to 12.2 ? Brix, and the dry weight of the bulbs, which presented variation of 6.4 7.5%. The presence of mulch provided savings of 5.7% in water depth at L4 and influenced significantly the production variables. Despite having reduced TMSB, has provided to culture the increase in USA, PTB, MMFB and DMB, and influenced the distribution of the percentage of bulbs in diameter classes, with 35% reduction in the percentage of bulbs classified as class 1 (<35mm with no or very low commercial value) and increased by 31 and 30.8%, respectively, the percentage of bulbs classified in class 3 and 3 full (50 to 70 mm, of best commercial value). This the distribution was significantly influenced by different levels of irrigation and, in general, the percentage of bulbs classified in classes of larger diameter (best commercial value) decreased the percentage of bulbs grouped in classes of reduced diameter increased with the reduction of blade water applied. It was concluded, based on the results, that the technique of irrigation promotes improvements in the yield components of onion and the use of mulch on the soil favors better yields and quality of bulbs, with increased EUA. |

Assim objetivou-se avaliar os efeitos de diferentes l?minas de irriga??o aplicadas via m?todo de gotejamento e da utiliza??o de palhada de capim-elefante (Pennisetum purpureum Schum. cv. Cameron) como cobertura morta do solo nas vari?veis de produ??o de bulbos de cebola (Allium cepa L.) e na sua efici?ncia de uso da ?gua, sob cultivo agroecol?gico. O experimento foi conduzido no per?odo de Maio a Setembro de 2012 no Sistema Integrado de Produ??o Agroecol?gica, localizado entre as coordenadas 22?45` S e 43?41`W, localizado no munic?pio de Serop?dica-RJ. O delineamento experimental adotado foi em Blocos completos casualizados, com parcelas divididas, com 10 tratamentos e 7 repeti??es, caracterizados pela presen?a (CC) e aus?ncia de palhada como cobertura do solo (SC) e por cinco l?minas de irriga??o relativas ?s porcentagens da evapotranspira??o da cultura (ETc): 22, 45, 75 e 100%, denominadas l?minas L1, L2, L3 e L4, respectivamente, al?m da l?mina L0, caracterizada pela aus?ncia de irriga??o. As vari?veis de produ??o avaliadas foram produtividade total de bulbos (PTB), massa m?dia fresca de bulbos (MMFB), teor de mat?ria seca dos bulbos (TMSB), di?metro m?dio de bulbos (DMB), sendo estes divididos em 7 classes de di?metro, teor de s?lidos sol?veis totais (TSST) e a efici?ncia do uso da ?gua (EUA). Os dados foram tabulados e submetidos ? an?lise de vari?ncia e as m?dias foram avaliadas com aux?lio da t?cnica de regress?o, para o fator l?mina de irriga??o, e do teste f para compara??o de m?dias no que se refere ao fator cobertura do solo. O fator l?mina de irriga??o influenciou significativamente as vari?veis PTB, MMFB e DMB que variaram, respectivamente, de 11,4 a 52,1 Mg ha-1, de 28,6 a 130,3 g e de 3 a 5 mm, tendo, em m?dia, 98,6% de suas varia??es explicadas pela regress?o polinomial de segunda ordem. A l?mina tamb?m influenciou significativamente na regress?o polinomial de segunda ordem (condi??o SC) na EUA, que variou de 107,08 a 140,67 kg ha-1 mm-1 e na regress?o linear com valores variando de 148,35 a 218,10 kg ha-1 mm-1 (condi??o CC). Ao contr?rio, a l?mina aplicada n?o afetou significativamente os teores de s?lidos sol?veis totais, que variaram de 9,9 a 12,2 ?BRIX, e a massa seca de bulbos, que apresentaram varia??o de 6,4 a 7,5%. A presen?a de cobertura morta proporcionou uma economia de 5,7% em l?mina de irriga??o no L4 e influenciou significativamente as vari?veis de produ??o. Apesar de ter reduzido o TMSB, proporcionou ? cultura o incremento da EUA, PTB, MMFB e DMB, e influenciou na distribui??o do percentual de bulbos em classes de di?metro, com redu??o de 35 % no percentual de bulbos enquadrados na classe 1 (< 35mm, sem ou baix?ssimo valor comercial) e aumento em 31 e 30,8%, respectivamente, a porcentagem de bulbos enquadrados nas classes 3 e 3 cheio (50 a 70 mm, de melhor valor comercial). Esta distribui??o foi influenciada significativamente pelos diferentes n?veis de irriga??o e, de modo geral, o percentual de bulbos enquadrados nas classes de maiores di?metro (de melhor valor comercial) diminuiu e o percentual de bulbos enquadrados em classes de di?metro reduzido aumentou com a redu??o da l?mina de ?gua aplicada. Concluiu-se, com base nos resultados, que a t?cnica da irriga??o promove melhorias nas vari?veis de produ??o da cebola e que a utiliza??o de cobertura morta no solo favorece melhores rendimentos e qualidade dos bulbos, com aumento da EUA.Submitted by Jorge Silva (jorgelmsilva@ufrrj.br) on 2019-10-30T17:44:48Z No. of bitstreams: 1 2014 - Eduardo Castro Ribeiro.pdf: 1923089 bytes, checksum: 140c5d2d6ee3e292b2080dd765a57de4 (MD5)Made available in DSpace on 2019-10-30T17:44:48Z (GMT).

description |
The technique of irrigation and use of soil mulch can cause changes in the variables of crop production. Thus aimed to evaluate the effects of different blades irrigation applied through drip method and use of straw elephant grass (Pennisetum purpureum Schum. cv. Cameron) as mulch on the soil variables of production of onion bulbs (Allium cepa L.) and its water use efficiency under agroecological farming. The experiment was conducted from May to September 2012 in the Integrated system Agroecological Production, located between the coordinates 22 ? 45 'S and 43 ? 41' W, in the municipality of Serop?dica-RJ. The experimental design was a randomized complete blocks with split plots, with 10 treatments and 7 replications, characterized by the presence (CC) and absence straw how mulch soil (SC) and five blades irrigation caracterized for percentages of the crop evapotranspiration (ETc) 22, 45, 75 and 100%, termed blades L1, L2, L3 and L4, respectively, and the blade L0, characterized by the absence of irrigation. The variables evaluated were the total productivity of bulbs (PTB), Average fresh bulb weight (MMFB), dry matter content of the bulbs (TMSB), diameter bulbs (DMB), which are divided into 7 classes in diameter, total soluble solids content (TSST) and the efficiency of water use (EUA). Data were tabulated and subjected to analysis of variance and means were assessed with the regression technique to the blade factor for irrigation, and of the f test for comparison of means with regard to the coverage factor of the soil. The blades irrigation factor significantly affected the variables PTB, MMFB and DMB ranging, respectively, from 11.4 to 52.1 t ha-1, 28.6 to 130.3 g and 3 to 5 mm, and in average 98.6% of their variations were explained by the polynomial regression second-order. The blade also influenced significantly in the polynomial regression second-order (condition SC) the EUA, which ranged from 107.08 to 140.67 kg ha-1 mm-1 and in the linear regression with values ranging from 148.35 to 218.10 kg ha-1 mm-1 (CC condition). Unlike, the applied blade did not significantly affect the levels of total soluble solids, ranging from 9.9 to 12.2 ? Brix, and the dry weight of the bulbs, which presented variation of 6.4 7.5%. The presence of mulch provided savings of 5.7% in water depth at L4 and influenced significantly the production variables. Despite having reduced TMSB, has provided to culture the increase in USA, PTB, MMFB and DMB, and influenced the distribution of the percentage of bulbs in diameter classes, with 35% reduction in the percentage of bulbs classified as class 1 (<35mm with no or very low commercial value) and increased by 31 and 30.8%, respectively, the percentage of bulbs classified in class 3 and 3 full (50 to 70 mm, of best commercial value). This the distribution was significantly influenced by different levels of irrigation and, in general, the percentage of bulbs classified in classes of larger diameter (best commercial value) decreased the percentage of bulbs grouped in classes of reduced diameter increased with the reduction of blade water applied. It was concluded, based on the results, that the technique of irrigation promotes improvements in the yield components of onion and the use of mulch on the soil favors better yields and quality of bulbs, with increased EUA. |
