Rendimento da pimenta cayenne em função de diferentes tensões de água no solo

Abstract: RESUMOObjetivou-se, neste trabalho, avaliar as tensões de água no solo em duas fases fenológicas (vegetativa e reprodutiva) da cultura da pimenta Cayenne, cultivada em ambiente protegido e irrigada por gotejamento. Foram instalados dois experimentos utilizando-se um delineamento inteiramente casualizado cujos tratamentos foram definidos por quatro tensões de água no solo (20, 40, 60 e 120 kPa) e quatro repetições. Os maiores valores de massa média de frutos por planta foram obtidos para a tensão de 20 kPa, sen… Show more

“…VILAS BOAS et al (2007) achieved maximum values of 36.5 and 33.2 t ha -1 for crisp lettuce without mulching by drip irrigating with 249.1 and 244.9 mm, respectively. This same inverse relationship between yield reduction and level of tension was verified for several different crops, corroborating with LIMA et al (2013) who studied cayenne pepper and CARVALHO et al (2012) with peas in protected cultivation with different soil water tensions. This reduction supports mulching, since it favors microclimate for root growth and absence of competition with weeds.…”

“…O sistema de cultivo e o manejo da irrigação têm sido determinante para o rendimento satisfatório da pimenteira, sobretudo nas regiões Sul, Sudeste, Centro Oeste e Nordeste do país (LIMA et al, 2013). Segundo Sezen et al (2006), o manejo da água para a cultura da pimenta é importante durante todo desenvolvimento da planta, tendo influência no estabelecimento do estande, assim como também nos problemas funcionais na emissão de frutos e na sua qualidade.…”

“…Yield depends on the number of fruits and fruit mean weight, and in this case the main difference observed between treatments was in the number of fruits per plant. Nevertheless, in general, as the water deficit increases there is a trend of reduction in fruit weight, as observed by Bilibio et al, (2011), Martin-Vertedor et al (2011, Lima et al (2013) and Sousa et al (2014) for rapeseed, olive, Cayenne pepper and peanut, respectively.…”
