Abstract
Com o objetivo de estudar a adubação do arroz de sequeiro, foram instalados cinco ensaios na variação Lins dos Solos Podzolizados de Lins e Marília, escolhendo-se os locais de acôrdo com o teor de fósforo. Utilizou-se ocultivar 'Pratão' e o delineamento fatorial 3³ para N, P e K, acrescentando-se um tratamento extra com microelementos. Sòmente em uma localidade houve reação ao nitrogênio. Houve forte reação à adubação fosfatada, mostrando-se a aplicação de 60 kg/ha de P2O5 suficiente para atingir o máximo de produção. Os locais em que o teor de PO4-³ solúvel em H2SO4 0,05 N no solo era igual ou maior que 0,08 e.mg por 100 g de terra, não mostraram efeitos benéficos da adubação com fósforo. O potássio induziu aumentos de produção em apenas uma localidade. A mistura de microelementos não proporcionou acréscimos de produção em quaisquer dos ensaios.
Upland rice is one of the principal cultures in the State of São Paulo. However, there is no doubt that the productivity of this crop is low. Among the problems that are responsible for this low productivity is the lack or deficient use of fertilizers. The N, P, K and microelements were then considered. The present paper shows the results of five fertilizer experiments with upland rice, in which the cultivar 'Pratão' was used. The scheme was a factorial 3x3x3 with an extra treatment for microelements and the experiments were installed on Podzolized Soils on Calcareous Sendstone Lins variation. Through chemical analysis of a great number of soils, the places were chosen. For this purpose special consideration was given to the e.mg PO4-³ per 100 f of soil content. Nitrogen only affected the production in one place, in which the plant residues of corn were incorporated in the soil. Under 0.08 e.mg PO4-5 per 100 g of soil, phosphorus affected the production of rice. The use of 60 kg/ha of P2O5 was sufficient for the higher yields. The use of potassium was efficient in only one place. No beneficial effect was noted with the use of microelements.
