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...

Background Loche (Cucurbita moschata) is a pre-Columbian squash that is cultivated exclusively in the northern coast of Peru, Lambayeque. This crop is notable for the presence of warts in its skin and for its vegetative reproduction as it commonly lacks of seeds in fruits. Currently, loche may be considered a new product for international markets, recognizing the gastronomy of Lambayeque in the world and dynamizing the Peruvian agro-export area. However, genomic information about this squash is very limited.

Water scarcity and the planning of socioeconomic activities are challenges in the management of water resources. Therefore, the objective of this study was to use reliability indicators (RI) to simulate management scenarios in the Lurin River Basin. First, flow rates for the period 1969–2019 were calculated using the EvalHid HBV hydrological model and SIMGES, both from the AQUATOOL decision support system, to simulate demands. The estimation of agricultural demand IRs was made under three conditions: that the deficits for one, two, and 10 years should not exceed 20–40, 40–60, and 80–100% of the annual demand. The goodness-of-fit indices obtained for flow calibration were 0.716, 0.89, and 0.901 for Nash index (NSE), Nash natural logarithm (Ln NSE), and Pearson's correlation coefficient (R), representing the values of satisfactory, very good, and good, respectively. Agricultural de...

Ante la creciente escasez del agua para la agricultura, el incremento de la demanda de alimentos y los futuros escenarios de sequía que nos plantea el cambio climático es indispensable diseñar nuevas tecnologías que contribuyan a un menor consumo de agua. En esta investigación se han empleado imágenes de alta resolución para estimar la evapotranspiración en arrozales aplicando el modelo de balance de energía METRICTM (Mapping Evapotranspiration at High Resolution using Internalized Calibration). Para ello, se monitorizaron 5900 m2 de cultivo bajo riego por inundación continua (IC) y 2600 m2 bajo la técnica de riego de alternancia humedecimiento y secado (AWD, por sus siglas en inglés), además de algunas parcelas con filtración lateral. Se realizaron 10 vuelos entre las etapas de macollamiento y floración, cinco vuelos con un VANT Matrice 210 con una cámara multiespectral ...

En el Perú, el mango variedad Kent, es la fruta de mayor exportación e interés socioeconómico para el país, producida tradicionalmente bajo una fertilización convencional; sin embargo, su productividad se ve afectada debido al incremento de los costos de producción principalmente de los fertilizantes. Objetivo: Evaluar el efecto de la aplicación de compost y biol en las variables productivas del cultivo de mango var. Kent. Metodología: Se evaluaron los tratamientos T0: testigo; T1: compost 5 t ha-1 ; T2: compost 15 t ha-1 ; T3: biol 5%; T4: biol 10%; T5: compost 5 t ha-1 + biol 5%; T6: compost 5 t ha-1 + biol 10%; T7: compost 15 t ha-1 + biol 5% y T8: compost 15 t ha-1 + biol10%. Las variables evaluadas fueron: diámetro polar del fruto (DPF-mm), diámetro ecuatorial del fruto (DEF-mm), diámetro diagonal del fruto (DDF-mm), tasa de crecimiento promedio por día (TCPD-mm día-1 ...

Los individuos del género Prosopis sp. conocidos como algarrobos; son especies claves en el desarrollo del bosque seco y recuperación de áreas degradadas en la Costa norte del Perú. La evaluación de plantaciones, cálculo de la biomasa aérea forestal (BAF) y carbono almacenado representa un papel importante en el manejo forestal y mitigación del cambio climático. Este estudio evalúa metodologías de monitoreo a través del uso de imágenes multiespectrales y LiDAR acopladas a un VANT, con la finalidad de realizar su validación y generar modelos que permitan estimar el carbono almacenado. Se evaluaron siete especies de Prosopis sp. con la metodología convencional y se encontraron diferencias significativas entre las especies para las características dasométricas e índices de vegetación, así como en la comparación con los datos obtenidos con el LiDAR. Se seleccionaron mode...

The dry forests of northern Peru are home to extensive populations of algarrobo (Neltuma spp.). Its fruit serves as feed for goats and is used in various agro-industrial products. However, the nutritional quality can be influenced by the physicochemical properties of the soil and vegetation coverage. The objective of this study was to understand and predict the concentration of protein and ether extracts of carob and evaluate its relationship with soil properties and vegetation indices. Principal component analysis (PCA) and correlation analyses were conducted. The prediction of protein and ether extract was carried out using the Eureqa-Formulize software 1.24.0. In the PCA, protein showed a positive relationship with ash and ether extract but a negative relationship with moisture. Likewise, moderate correlations were observed between protein and ash content (0.51). Protein also showed p...
