This work established a hyperspectral library of important foliar diseases of wheat in time series to detect spectral changes from infection to symptom appearance induced by different pathogens. The data was generated under controlled conditions at the leaf-scale. The transition from healthy to diseased leaf tissue was assessed, spectral shifts were identified and used in combination with histological investigations to define developmental stages in pathogenesis for each disease. The spectral signatures of each plant disease that are indicative of a certain developmental stage during pathogenesis - defined as turning points - were combined into a spectral library. Different machine learning analysis methods were applied and compared to test the potential of this library for the detection and quantification of foliar diseases in hyperspectral images. All evaluated classifiers provided a high accuracy for the detection and identification for both the biotrophic fungi and the necrotrophic fungi of up to 99%. The potential of applying spectral analysis methods, in combination with a spectral library for the detection and identification of plant diseases is demonstrated. Further evaluation and development of these algorithms should contribute to a robust detection and identification system for plant diseases at different developmental stages and the promotion and development of site-specific management techniques of plant diseases under field conditions.

Yield Of Oats

Abstract The article presents the results of many years of experiments on the development of energy-saving farming systems. Preference in crop rotations should be given to multi-depth combined treatments that provide high productivity and are characterized by high-energy efficiency. Data on the yield of grain and leguminous crops in a six-field grain crop rotation with constant dump and combined longline tillage shows that the yield of oats in the first year of rotation according to the experimental variants was the same and amounted to 3.60 t/ha. In the second year of winter wheat yield in the variant with longline tillage was by 0.20 t/ha more in comparison with a plow on row, in the third year the difference in yield of spring barley on options for primary processing amounted to 0.30 t/ha in favor of combined tiered processing, in the fourth year the yield of peas has also been found to 0.40 t/ha more, also on the option of combined longline processing in the fifth year of the rotation crop of winter triticale. The yield of oats was 0.30 t/ha higher, and in the sixth year the yield of oats was 0.40 t/ha higher on the variant of combined longline processing.
