Abstract: RESUMOObjetivou-se, com este trabalho, avaliar os componentes agronômicos e o índice de colheita de genótipos de amendoim ereto e rasteiro submetidos a 27 dias de suspensão hídrica, no inicio da fase vegetativa. O experimento foi conduzido em casa de vegetação sob o delineamento inteiramente casualizado com esquema fatorial 8 x 2 (genótipos x tratamentos hídricos) com cinco repetições. As variáveis analisadas foram: peso seco da planta total, peso seco das raízes, altura da haste principal, produção de vagens … Show more

“…In addition, it reduces the physiological development of the crop and diminishes its productive potential. A fact also observed by Duarte et al (2013) analyzing plant height and number of pods per plant, where the crop, when submitted to water deficit, presented significantly lower values.…”

“…Similar results were found by Sousa et al (2014) who also evaluated irrigation levels following the Penman-Monteith method proposed by FAO 56 (Allen et al, 1998), but in a drip system. According to Duarte et al, (2013) cultivars of erect habit (IAC Tatu ST) are more susceptible to increased nitrogen doses and have a greater ability to adjust to water scarcity; this allows the cultivar to present significant responses to dose increase and irrigation level when dealing to plant height. Arruda et al (2015) studying the cultivar IAC Tatu, under conditions of water deficit, observed little tolerance to drought and high productive potential, besides verifying that plant height is a variable highly influenced by water deficit (Figure 02).…”

“…Water deficit conditions cause changes in the cell membrane, increase respiration, inhibit photosynthesis, decrease dry matter production and cause premature senescence of production components (Upadhyaya et al 2011, Pereira et al 2012, Duarte et al 2013.…”

“…Therefore, a higher straw production directly decreases the expression of harvest index. Duarte et al (2013) considered the harvest index an identification component of peanut genotypes tolerant to water stress. In corn cultivation, the harvest index was used in the identification of agronomic performance to different climate scenarios in Central-West of Brazil (Minuzzi and Lopes, 2015).…”
