This work presents quantitative detection of water stress and estimation the level: none, light, moderate, severe on potato crops. We use hyperspectral imagery state art machine learning algorithms: random decision forest, multilayer perceptron, convolutional neural networks, support vector machines, extreme gradient boost, AdaBoost. The in crops is carried out two different phenological stages...

In this article, the reaction of winter wheat varieties to fertilizers in irrigated soils varietal-soil-fertilizer system was studied and a feeding developed recommended for each soil-climatic conditions varieties. Appropriate fertilizer standards have been variety, which increased germination, weeding, accumulation, tuberization, spike formation, dry mass grain quality, yield structure wheat. ...
