Resumo: A study to verify the effect of P supplementation in the dry and wet season was conducted on fertilized guineagrass (Panicum maximum Jacq.) pasture. The experiment was carried out at 20°14’30” south latitude and 56°22’42” west longitude, in the municipality of Miranda, MS, Brazil, and lasted for 719 days. A total of 176 Nelore cross-bred steers were used in the following treatments: 1. NaCl + P + micro-elements during all year; 2. NaCl + P + micro-elements in the wet season and NaCl + micro-elements in the dry season; 3. NaCl + micro-elements in the wet season and NaCl + P + micro-elements in the dry season; and 4. NaCl + micro-elements during all the year. The experiment did not show significant difference (P > 0,05) among treatments. The average final weights per animal were 436,4 kg for treatment 1, 421.7kg for 2,428.0kg for 3, and 422.5kg for treatment 4. Biopsy of rib-bone showed low Ca and P for all treatments. The forage was deficient in P, Na, Zn and Cu and the soil in Zn and Cu.

O experimento foi conduzido na fazenda Itaipu, a 20°14’30” de latitude sul e 56°22’42” de longitude oeste, no município de Miranda, MS, com duração de 719 dias. Foram usados 176 novilhos nelorados, distribuídos nos seguintes tratamentos: 1. NaCl + P + microelementos durante todo o ano; 2. NaCl + P + microelementos no período chuvoso e NaCl + microelementos no período seco; 3. NaCl + microelementos no período chuvoso e NaCl + P + microelementos no período seco; e 4. NaCl + microelementos durante o ano todo. Não houve diferença estatisticamente significativa entre tratamentos. Os pesos médios finais dos animais foram: 436,4; 421,7; 428,0 e 422,5 kg para os tratamentos 1, 2, 3 e 4 respectivamente. Não houve ganho adicional devido à suplementação sazonal com P em pastagens adubadas. As análises de biópsia de osso (costela) indicaram níveis baixos de Ca e P nos animais de todos os tratamentos. As forrageiras mostraram níveis deficientes de P, Na, Zn e Cu. O solo de alguns pastos tinham níveis baixos de Zn e Cu.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraSousa, Júlio César deGomes, Ronaldo Frederico CorrêaRosa, Ivan ValadãoCardoso, Esther Guimarães2014-10-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/16140Pesquisa Agropecuaria Brasileira; v.20, n.8, ago. 1985; 981-990Pesquisa Agropecuária Brasileira; v.20, n.8, ago. 1985; 981-9901678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/16140/10306info:eu-repo/semantics/openAccess2014-04-17T11:58:55Zoai:ojs.seer.sct.embrapa.br:article/16140Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-17T11:58:55Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
