Resposta do arroz irrigado ao fornecimento de fósforo e densidade de semeadura em sistema pré-germinado

Abstract: RESUMO: O arroz irrigado apresenta elevada importância socioeconômica para o estado de Santa Catarina, contudo, estudos que visam a definição da densidade de semeadura e a resposta do arroz irrigado ao fornecimento de fósforo ainda são escassos. Desta maneira, este trabalho teve como objetivo avaliar a produtividade do arroz irrigado, conduzido em sistema pré-germinado, em função da densidade de semeadura e da adubação fosfatada. O experimento foi conduzido em blocos casualizados e os tratamentos foram arranja… Show more

“…Nevertheless, both cases did not exceed the maximal limit of 45% used by Xi et al (2020) when evaluating the efficiency of fluted roller seed metering devices in the distribution of wheat seeds. Gutz et al (2019) show that irrigated rice presents high phenological plasticity, providing statistically similar yields between the sowing densities of 60 and 150 kg ha -1 . Nevertheless, according to Chauhan & Opeña (2013), low sowing rates are only possible if the seed metering devices can distribute them evenly and with low levels of mechanical damage.…”

“…The water-seeded system allows the reduction of herbicides used for weed control, and the soil preparation and seedbed leveling are performed with reduced ponding water depth. The seeding is made with pre-germinated seeds distributed in the ponding water depth (Machado et al, 2006;Sosbai, 2018;Gutz et al, 2019).…”
