Resumo: Choosing species with high phytomass production to be cropped in no tillage system is extremely important in dry winter regions. The purpose of this research was to study plant biomass production and accumulation of nutrients in shoots of Giant Guinea sorghum plants (Sorghum bicolor subspecies bicolor race Guinea) sown in different sowing dates. A randomized complete block design with six treatments and four replications was performed. Treatments consisted of six sowing dates (09/25/2000; 10/25/2000; 11/24/2000; 12/22/2000; 02/22/2001 and 04/03/2001). At flowering, dry matter production, number and diameter of stems and plant height were evaluated. Macro and micronutrient levels and accumulation were determined as well as C/N ratio. Plant cycle decreased as sowing date was delayed and, consequently, dry matter production and C/N ratio decreased as well. The opposite was observed for nutrient contents. "Giant Guinea" sorghum is sensitive to photoperiod thus late sowing reduces plant development, which leads to low biomass production and nutrient accumulation. "Giant Guinea" sorghum cultivated as cover crop is a good option when implementing no tillage system due to high dry matter production and N, P, and K recycling.

O objetivo deste trabalho foi avaliar a produção de fitomassa e acúmulo de nutrientes na parte aérea das plantas de sorgo Guiné gigante (Sorghum bicolor subespécie bicolor raça guinea), semeados em diferentes épocas de semeadura. Foi utilizado um delineamento em blocos ao acaso, com seis tratamentos e quatro repetições. Os tratamentos foram constituídos por seis épocas de semeadura (25/09/2000; 25/10/2000; 24/11/2000; 22/12/2000; 22/02/2001 e 03/04/2001). Por ocasião do florescimento das plantas, avaliou-se a produção de matéria seca, o número e diâmetro de colmos e a altura das plantas. Também foi determinado o teor e acúmulo de macro e micronutrientes, além da relação C/N. O ciclo das plantas diminuiu com o atraso da época de semeadura, e, conseqüentemente, a produção de matéria seca e a relação C/N também foram menores. Comportamento contrário foi observado para o teor de nutrientes. O sorgo de Guiné gigante é sensível ao fotoperíodo e, portanto, semeaduras mais tardias ocasionam diminuição do crescimento das plantas, produção de biomassa e acúmulo de nutrientes. Esta espécie consiste em uma boa opção para cultivo como planta de cobertura no sistema de semeadura.Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)São Paulo State Univ, Coll Agr Sci, Dept Crop Sci, BR-18610307 Botucatu, SP, BrazilAgrobusiness Technol Agcy, BR-16900000 Andradina, SP, BrazilEmpresa Brasileira de Pesquisa Agropecuária (EMBRAPA) Fisheries Aquaculture & Agr Syst, BR-77015012 Palmas, TO, BrazilEmpresa Brasileira de Pesquisa Agropecuária (EMBRAPA) Western Reg Agr BR 163, BR-79804970 Dourados, MS, BrazilSão Paulo State Univ, Coll Agr Sci, Dept Crop Sci, BR-18610307 Botucatu, SP, BrazilUniv Federal Ceara, Dept GeolUniversidade Estadual Paulista (Unesp)Agrobusiness Technol AgcyEmpresa Brasileira de Pesquisa Agropecuária (EMBRAPA)Mateus, Gustavo PavanBorghi, EmersonAmaral Castro, Gustavo Spadotti [UNESP]Garcia, Rodrigo ArroyoCosta Crusciol, Carlos Alexandre [UNESP]2014-05-20T13:20:11Z2014-05-20T13:20:11Z2011-10-01info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article1000-1008application/pdfhttps://www.embrapa.br/pesca-e-aquicultura/busca-de-publicacoes/-/publicacao/903430/biomass-production-and-accumulation-of-nutrients-in-shoots-of-giant-guinea-sorghum-plantsRevista Ciência Agronomica.
