Four treatments were established: T1 (control), T2, T3, T4 at 0%, 30%, 60%, 90% decrease (RD), respectively, with black shedding netting. following recorded for each treatment:...

Despite the global expansion of forest plantations in Chile, their effect on biology properties soil has still been only scarcely studied. Land use change Chilean Coastal Cordillera (36° to 40° S) is mainly attributed conversion native agriculture and (Eucalyptus globulus Pinus radiata de Don). The aim this paper was evaluate changes microbial composition (PCR-DGGE) enzyme activity after substitution a (e.g., Nothofagus spp.) by fast-growing exotic species cropping. most important factors...

Legacy and Duke are the main blueberry (Vaccinium corymbosum L.) cultivars grown in Chile, with 32.8% of total Chilean cultivated area this fruit. The market demands fruit firmness, size, weight, quality attributes, which improved by some agronomic management practices such as winter pruning. present study evaluated effect on attributes yield five bud load levels, regulated pruning during two consecutive seasons, ʻLegacyʼ ʻDukeʼ. was conducted three commercial orchards under different...

Durum wheat (Triticum turgidum L. var durum) is a species that accumulates cadmium (Cd). cultivars differ in their absorption ability of Cd; therefore, identifying and selecting genetic material with low Cd accumulation reduces human exposure to this toxic element. In the present study, concentration was evaluated three Chilean durum (Llareta-INIA, Corcolén-INIA, Lleuque-INIA) grown four locations varying concentrations soils. The objective study evaluate response these different doses terms...

Calafate fruits have a high content of phenolic compounds and an antioxidant activity up to four times higher than that blueberries. The establishment calafate orchard irrigation responses on fruit soil characteristics been scarcely studied. Therefore, the objective this study was evaluate effect water replenishment rate: 0%, 50%, 100% 150% reference evapotranspiration (ET0), microbiological activity, plant physiological response, yield chemical composition in orchard. results showed at 50%...

Mulch is widely used in blueberry cultivation for weed control; however, there still uncertainty as to how the use of different types mulch alters leaf photosynthetic behavior and quality productivity fruit. The objective our research was evaluate effect on physiological, yield characteristics blueberries. Three treatments were established: T1 (control), T2 (pine bark) T3 (geotextile) two cultivars: Ochlockonee Legacy. parameters measured were: photochemical quantum photosystem II (YII),...

Limited information exists regarding the impact of planting density on soil fertility, plant productivity, and phenolic content calafate (Berberis microphylla G. Forst.) fruits. This study aimed to assess effects soil, plants, fruits in a orchard. Four treatments were employed: High-density (HD; 6667 plants ha-1), traditional (TD; 3333 medium (MD; 2222 low (LD; 1667 ha-1). In TD exhibited 28% increase basal respiration compared with MD, 29% urease HD. Additionally, enhanced N availability by...

Cadmium (Cd) is one of the heavy metals commonly present in soils that toxic for living organisms and carcinogenic humans. The uptake Cd by a crop depends on various factors such as soil properties, plant-soil interaction, fertilizer management, previous crop. aim study was to evaluate residual effect three rates applied preceding crops (durum wheat [<i>Triticum turgidum</i> L. var durum], white lupine [<i>Lupinus albus</i> L.], narrow-leafed [<i>Lupineus angustifolius</i> L.]) total dry...
