El trabajo de investigación se realizó en el paraje de Chaupimarca ubicado en el distrito de El Mantaro en la provincia de Jauja, cuya finalidad fue evaluar los tubérculos semilla de papa almacenados en diferentes tipos de almacenamiento. El objetivo del estudio fue: Determinar el efecto del tipo de almacenamiento de tubérculos semilla de papa cultivar Canchán sobre el rendimiento de tubérculos de papa. Se utilizó el diseño de Bloques Completamente Randomizados con tres tratamientos y tres repeticiones. De acuerdo a los resultados, indica que: en el porcentaje de emergencia sobresalió el tratamiento 1 (campo libre) con un promedio de 97 por ciento; mientras que, en el vigor de planta sobresalieron los tratamientos 1 (campo libre) y 2 (luz difusa) con promedios de 1,100 cm y 1,047 cm; en la biomasa de la parte aérea sobresalieron los tratamientos 1 (campo libre) y 2 (luz difusa)...

Remote sensing is essential in precision agriculture as this approach provides high-resolution information on the soil's physical and chemical parameters for detailed decision making. Globally, technologies such as remote sensing and machine learning are increasingly being used to infer these parameters. This study evaluates soil fertility changes and compares them with previous fertilization inputs using high-resolution multispectral imagery and in situ measurements. A UAV-captured image was used to predict the spatial distribution of soil parameters, generating fourteen spectral indices and a digital surface model (DSM) from 103 soil plots across 49.83 hectares. Machine learning algorithms, including classification and regression trees (CART) and random forest (RF), modeled the soil parameters (N-ppm, P-ppm, K-ppm, OM%, and EC-mS/m). The RF model outperformed others, with R² values of...

Precision agriculture aims to improve crop management using advanced analytical tools.In this context, the objective of this study is to develop an innovative predictive model to estimate the yield and morphological quality, such as the circularity and length–width ratio of potato tubers, based on phenotypic characteristics of plants and data captured through spectral cameras equipped on UAVs. For this purpose, the experiment was carried out at the Santa Ana Experimental Station in the central Peruvian Andes, where advanced potato clones were planted in December 2023 under three levels of fertilization. Random Forest, XGBoost, and Support Vector Machine models were used to predict yield and quality parameters, such as circularity and the length–width ratio. The results showed that Random Forest and XGBoost achieved high accuracy in yield prediction (R2 > 0.74). In contrast, the predi...

The lack of precise methods for estimating forest biomass results in both economic losses and incorrect decisions in the management of forest plantations. In response to this issue, this study evaluated the effectiveness of using the DJI Zenmuse L1 LiDAR, mounted on a DJI Matrice 300 RTK UAV, to provide three-dimensional measurements of canopy structure and estimate the aboveground biomass of Eucalyptus globulus. Various LiDAR metrics were employed alongside field measurements to calibrate predictive models using multiple regression and machine learning algorithms. The results at the individual tree level show that RF is the most accurate model, with a coefficient of determination (R²) of 0.76 in the training set and 0.66 in the test set, outperforming Elastic Net (R² of 0.58 and 0.57, respectively). At the plot level, a multiple regression model achieved an R² of 0.647, highlighting ...
