Growth and Production of rice (oryza sativa l.) under different fertilization plans with Silicon

Abstract: The application of fertilizers to rice crops constitutes a large percentage of productions costs, which in recent years have increased; therefore, it is necessary to implement alternatives that optimize the application and improve profitability. It was evaluated the effect of different doses and application times of a fertilizer with silicon on a rice crop, Fedearroz 50 variety. The experimental design was completely randomized with a 2 × 5 factorial arrangement. The first factor was dose (20 and 40 kg ha -1 )… Show more

“…Rice water requirements change for each stage of growth, so the Markov chain process deals with this set of possible stages S and the set of possible actions A, where the effects of an action taken in a stage depend only on that stage and not on the prior history. We thus use the MCP approach to model the probabilistic transitions among a set of stages S = {s 1 , s 2 , • • • } [26], where each stage s i ∈ S is defined with a predetermined cumulative total soil water (TSW) range (Table 1). Water loss from each plot is monitored with a water level sensor and daily TSW calculations are summed to provide the cumulative value.…”

“…Water and fertilizer requirements for rice change for each stage of growth so the MCP deals with this set of possible stages S and the set of possible actions A, where the effects of an action taken in a stage depend only on that stage and not on the prior history. As in [1] we use MCP to model the probabilistic transitions among a set of stages S = {s 1 , s 2 , • • •} [7], but here instead of just irrigation requirements we also model fertilization requirements, where each stage s i ∈ S is defined with a predetermined cumulative total soil water (TSW) and total soil fertilizer (TSF) range appropriate for Muvumba Valley. Water and fertilizer loss from each plot are monitored with a water level (WL) and fertilizer level (FL) sensors.…”

“…Variables de respuesta. La longitud de tallo floral se midió durante 14 semanas después del pinch y se ajustó a un modelo logístico doble sigmoide, el cual es uno de los modelos que mejor describe el crecimiento de las variables biológicas (Álvarez-Herrera et al, 2017). Este modelo se determinó mediante la ecuación (1):…”
