The use of pesticides assists in integrated programs that aim high yield and quality grains irrigated rice ( Oryza sativa L.). However, the can pose risk to as well environment general population. Therefore, objective this study was investigate dissipation persistence fungicides (azoxystrobin difenoconazole) insecticides (lambda‐cyhalothrin thiamethoxam) irrigation water, soil, plant, panicle, grain. conducted field during 2011/2012 crop season, with applied aerial parts plants, samples were...
Uma das práticas desafiadoras de manejo é aumentar a produção arroz utilizando menos água. O experimento foi realizado nas safras 2010/11 e 2011/12 na área experimental da Universidade Federal Santa Maria, Rio Grande do Sul. objetivo avaliar o rendimento grãos eficiência uso água semeadura no início final época recomendada. Os tratamentos foram as épocas (01/10/10 01/12/10) safra 2010/11, (27/09/11 07/12/11) 2011/12, com cinco repetições, cultivar utilizada 'IRGA 424'. Não houve diferença...
A incorporação da palha após a colheita do arroz dificulta redução banco de sementes; por outro lado, favorece decomposição e, consequentemente, possibilita o preparo antecipado área, viabilizando semeadura no período recomendado. O objetivo deste trabalho foi avaliar interferência diferentes manejos em áreas cultivadas com irrigado na viabilidade sementes arroz-vermelho. delineamento experimental utilizado blocos ao acaso, parcelas subdivididas tempo, quatro repetições. Os tratamentos foram...
Irrigated rice sowing season and red competition are among the main factors affecting grain yield. The objective of this work was to evaluate date irrigated moments application herbicide imazapyr + imazapic control management Eight experiments were performed at following dates (09/30, 10/19, 11/08 12/01) for 2010/2011 harvest (09/27, 10/17, 12/05) 2011/2012 season. treatments were: doses 105+35 g ha-1 in pre-emergence (PRE); 52.5+17.5 ha‑1 post-emergence (PRE POST); post- emergence (POST), a...

O arroz-vermelho é a principal planta daninha do arroz irrigado, pois afeta produtividade e qualidade. Objetivou-se avaliar ação de diferentes temperaturas na dinâmica germinação genótipo Puitá INTA CL biótipos arroz-vermelho, com sem superação da dormência. trabalho foi realizado em 2011, câmara B.O.D Fitotron Universidade Federal Santa Maria, Maria - RS. delineamento inteiramente casualizado quatro repetições. fator (A) composto pelas 13; 17; 21 25 ºC o (D) pela cultivar três Avaliaram-se...
The residue of imidazolinone herbicides in soil can be detrimental to soybean cultivation rotation with Clearfield® rice. Thus, this research aimed evaluate the ryegrass phytoremediation capacity on imazapyr+imazapic two moisture conditions off-season, and effect growth next growing season. Two experiments were conducted between 2016 2017 Santa Maria, Rio Grande do Sul state, Brazil. It was used randomized block design a 3 × 2 factorial. first factor being 0, 210 420 g c.p.·ha–1 formulated...
It is largely known that low temperature stress can affect rice (Oryza sativa L.) development and yield. However, most studies have focussed on unique uninterrupted cold treatment, which not representative of conditions for early sowing in temperate subtropical areas where nights are followed by warm days during vegetative stages. In order to elucidate whether plants could recover from the damages caused repetitive nights, we submitted a cold-tolerant (CT) cold-sensitive (CS) indica genotype...
Rice varieties from the Clearfield® system may present different tolerance levels to imidazolinone herbicides in function of application rate. The objective this research was evaluate phytotoxicity rates formulated mixture imazapyr+imazapic applied on two tolerant irrigated rice varieties. experiment carried out 2015/16 and 2016/17 growing seasons. A randomized complete block design used a factorial 2x6 with five replications. factor composed by Guri INTA CL IRGA 424 RI, B (525+175 g a.i....
The objective of this work was to evaluate the contribution main stem and tillers on grain yield irrigated rice, physiological quality seeds as a function fractionation topdressing nitrogen fertilization. experiment performed in field, at 2016-2017 2017-2018 growing seasons. treatments consisted five (N) topdress fractionations 50% rate V3, R0; 67% 33% 60% 20% V6, R0, 100% control without N application. panicle, each tiller class were harvested, (GY), components seed evaluated.
