This research work entitled "Evaluation of tour methods of controlled pollination on two ecotypes of white Pinion (Jatropha curcas L.) in the region San Martín" aimed to evaluate the results of four controlled pollination methods on two ecotypes of white pinion and determine the most effective controlled pollination. Design was applied in randomized complete block 4 x 2 factorial arrangement (4 x 2 ecotypes methods) with four (4) replications and eight (8) treatments. For improvement work, four methodologies controlled po'llination (bagging, sorbet and brush) and a control treatment (natural pollination) was applied. This experiment demonstrates that managed to develop methods for improving pollination white pinion and found that the Caballococha ecotype with the implementation of the straw method obtained higher grain yield per hectare 1 146.87 grains I ha. lt was found, also, that the...

Rice is a globally important crop and a staple in the diet of a large part of the world's population. This underscores the need for hybridization and improvement of rice genotypes to meet food demand in an environmentally sustainable manner. Geographic Information Systems (GIS) have proven to be valuable tools for the morphometric phenotyping of different genotypes. In this study, seven different rice genotypes were evaluated with the objective of selecting those with high yield. Multispectral imagery was used to develop prediction models based on supervised learning algorithms, including Linear Regression (LR), Support Vector Machine (SVM), Random Forest (RF), Elastic Net (EN), and Neural Networks (NN). The variables studied were plant height, number of panicles, number of tillers, and yield. The results showed the following performances: R² = 0.44 for plant height using Random Forest,...
