A medida que disminuye el agua de riego, la transpiración del cultivo disminuye, resultando en un incremento de la temperatura foliar y un aumento del índice de estrés hídrico del cultivo (IEHC). Por ello, en el estudio, se evaluó la respuesta del Capsicum a diferentes regímenes de riego, con mediciones periódicas de la temperatura de la hoja, la conductancia estomática y la estimación del IEHC. Los tratamientos consistieron en un riego por goteo completo (RO) y riego con déficit (RD-78 y RD-58) que recibieron el 78% y 58% del riego completo, aplicándose un volumen total de agua de 3363, 2618 y 1956 m3 ha-1 para RO, RD-78 y RD-58, respectivamente; and obteniéndose rendimientos máximos de 30,2, 13,9 y 12,9 t ha-1 con IEHC de 0,50, 0,62 y 0,54 en C. bacatum, C. annumm y C. chinense, respectivamente. Los mayores valores de conductancia estomática variaron de 724 a 887 mmol s-1...

The climatic data for the Jauja valley, Junín region, central highlands of Peru for the xxi century were evaluated, as simulated by the climatic models used in phase 5 by the Intercomparison of coupled models (CMP5). The models used were three (03): CSIRO Mk 3.6, MIROC ESM and CNRM CM5, respectively, at a spatial resolution of 1,875 × 1.86°, 2,81 × 1.87° and 1,41 × 1,40°, built by observed meteorological data in the Jauja valley during the 1975-2005 period, using the IPCC RCP2.6 and 8.5 scenario. The present work is to provide local climate projections for this area, generating a first future climate database for the region, as a decision-making tool for farmers and other users of the basin. The climatic projections show a significant warming from 2,0 degrees of temperature for the RCP2.6 scenario to 3,5 degrees of temperature for the RCP8.5 scenario expected in the entire evaluat...

Peruvian cotton (Gossypium hirsutum L.) has great acceptance and demand in the national and international textile market due to the excellent quality of its extra-long fiber, durability and resistance. To evaluate cotton cultivar performance, we need to use tools such as drones + sensors. However, these tools have not been widely used in the Peruvian agricultural area. Here we evaluated seven agro-morphological characters of 21 accessions of Del Cerro cotton cultivar from the National Institute of Agrarian Innovation of Peru with highthroughput phenotyping methods. We employed a Matrice 300 RTK unmanned aerial vehicle (UAV) with the MicaSense Dual Red Edge Blue multispectral sensor to assess plant height, yield, and spectral signature during physiological maturity stage; other morphological characters were manually scored. Multispectral monitoring revealed the phytosanitary status of the...

Here, we report the complete genome sequence of Erwinia sp. strain INIA01, a bacterium isolated from lesions of Zea mays from northern Peru. This genome possesses two circular replicons, a 4.2-Mb chromosome, and a 438-kb plasmid.
