Garlic (Allium sativum L.) is an important crop for domestic consumption in Peru. However, there is insufficient information available on crop management, particularly on fertiliser application to local cultivars. In order to evaluate the response of three garlic cultivars to three fertilisation methods, an experiment was conducted at the Donoso Experimental Station in Huaral district, a province of Lima. Three garlic cultivars were used as experimental materials: ‘Cincomesino’, ‘Arequipeño 14’ and ‘Margosino’. Three methods of fertilisation were applied as treatments: broadcast application before furrowing (M1), fertilisation in a superficial groove or false furrow (M2), and fertilisation in the lateral furrows, or band application (M3). The experiments were installed in three parcels for each cultivar, with a randomised complete block design for each parcel and four replic...

The aim of the study was to evaluate the in vitro propagation ability of 10 clonal lines of thorny globe artichoke (Cynara scolymus L.). The study methodology comprised five stages of evaluation. The stages evaluated were initiation, multiplication, rooting, acclimatization, and transplant to the field. The study began with the initiation of dissected shoot tips of 10 clonal lines in test tubes containing the Murashige and Skoog (MS) medium. Best results were obtained when explants were cultured on an induction medium containing MS + naphthalene acetic acid (NAA) 1.0 mg l−1 + benzyl aminopurine (BA) 1.0 mg l−1, highlighting clonal lines L-250, L-132, and L-62. Because of high rates of vitrification and phenolization in the initial stage, clonal lines L-24, L-127, and L-142 were discarded from the study. Therefore, only seven clonal lines were included for evaluation in the multiplica...

The work aims to identify and cartographically represent sensitive areas (scenarios) to river flooding in the lower section of the Madre de Dios hydrographic unit in the Peruvian Amazon, from the use of digital terrain models (DTM) and System for Automated Geoscientific Analyses (SAGA-GIS) free software, in version 2.2.5. It was produced a DTM with cells of 30 x 30 m hydrologically corrected, obtaining different maps of geomorphological factor (vertical distance from the drainage network and closed depressions) and hydrological factor (surface runoff, topographic wetness index, and modified catchment area). Integrating all this information the contrast index map was obtained, which once reclassified, allowed the spatial delineation of the flood scenarios and their categories of susceptibility.
