“…This is to be expected as nitrogen being a known growth promoting factor its application would naturally increase the vegetative growth and hence fresh herbage yield. These results were in agreement with findings of Singh and Singh (1992) who have also reported increased fresh herbage and oil yield with the application of 150 kg N ha -1 .…”

“…Java citronella responded well to applied N, with cultivars differing by up to 42% with respect to biomass production and up to 36% with respect to oil yield at the same N levels (Singh et al, 1980; Rao et al, 1983). Variation in biomass yield of a single cultivar of Java citronella with application of different types of urea has been demonstrated by Singh and Singh (1992) Nitrogen shortages and deficiency symptoms occur in many production areas in the United States and response to N has been widely examined (reviewed by Brown, 2003). In three mint species, oil production decreased with increased N application, being greatest with no applied N (Singh et al, 1989), but the oil quality did not vary appreciably with application of N fertilizer.…”

Effect of Irrigation with Secondary Treated Effluent on Essential Oil, Antioxidant Activity, and Phenolic Compounds in Oregano and Rosemary

Shortage of water throughout the world dictates utilization of marginal water for irrigation. Treated urban wastewater is a common alternative water source for irrigation in arid and semiarid regions. In this study we aimed to evaluate the eff ect of irrigation with secondary-treated effl uent on plant development, essential oil yield, antioxidant activity and selected antioxidant phenolic compounds in two commercial cultivars of the aromatic species, oregano (Origanum vulgare L.) and rosemary (Rosmarinus offi cinalis L.). Th e applied treated effl uent contained higher levels of Na, Cl, HCO 3 -1 , P, K, NH 4 +1 , NO 3 -1 , Ca+Mg, B, Mn, and Fe than the local potable water used as control, and were characterized by higher values of electrical conductivity (EC), pH, and sodium absorption ratio (SAR). Since effl uent eff ects on plants can become apparent only following several years of exposure, the plants were exposed to the water treatments for 3 yr. Despite the diff erences in water quality, the effl uent did not aff ect yield quantity and quality in either crop. Plant morphological development, biomass production, percent dry leaves of the total biomass, quantity and composition of the essential oil produced, antioxidant activity, and contents of selected antioxidant-phenolic compounds were not aff ected by irrigation with treated effl uent compared with potable water. Our results demonstrate that both oregano and rosemary are suitable as industrial crops for essential oil and antioxidant production under irrigation with secondary-treated municipal effl uent because their yield quantity and quality were not aff ected.

“…Seasonal communities with longer dry seasons exhibit limited photosynthetic activity and a marked annual periodicity of leaf flushing and senescence patterns, favoring a larger proportion of deciduous species [1,[10][11][12]. In fact, within seasonally dry tropical forests, nearly all plant individuals lose leaves in a synchronic deciduous behavior during the dry season [1,[13][14][15]. In areas with less pronounced dry seasons and elevated total annual rainfall, species and individuals may display different degrees of deciduousness, establishing communities with a wide range of leafing behaviors that may change according to soil moisture conditions, topography [8,16], and the intensity of the dry season ( [4] and references therein).…”

Leafing Patterns and Drivers across Seasonally Dry Tropical Communities

et al. 2019

Investigating the timing of key phenological events across environments with variable seasonality is crucial to understand the drivers of ecosystem dynamics. Leaf production in the tropics is mainly constrained by water and light availability. Identifying the factors regulating leaf phenology patterns allows efficiently forecasting of climate change impacts. We conducted a novel phenological monitoring study across four Neotropical vegetation sites using leaf phenology time series obtained from digital repeated photographs (phenocameras). Seasonality differed among sites, from very seasonally dry climate in the caatinga dry scrubland with an eight-month long dry season to the less restrictive Cerrado vegetation with a six-month dry season. To unravel the main drivers of leaf phenology and understand how they influence seasonal dynamics (represented by the green color channel (Gcc) vegetation index), we applied Generalized Additive Mixed Models (GAMMs) to estimate the growing seasons, using water deficit and day length as covariates. Our results indicated that plant-water relationships are more important in the caatinga, while light (measured as day-length) was more relevant in explaining leafing patterns in Cerrado communities. Leafing behaviors and predictor-response relationships (distinct smooth functions) were more variable at the less seasonal Cerrado sites, suggesting that different life-forms (grasses, herbs, shrubs, and trees) are capable of overcoming drought through specific phenological strategies and associated functional traits, such as deep root systems in trees.
