In recent times, nanotechnology is a branch of precision farming and sustainable agriculture where it expresses all sides of development for better utilization of resources in agriculture. Graphene oxide (GO) nanosheet is a two-dimensional crystal structure formed by a flat monolayer of sp² hybridized carbon atoms arranged in a hexagonal arrangement. Marigold (Tagetes erecta L.) and Calendula (Calendula officinalis L.) are commercially explored flower crops of the family Asteraceae. These flower species contain a sufficient amount of active compounds, used in various commercial sectors. Graphene oxide nanosheets were produced by the commercial chemical method. Characterization of GO is done on powder X-ray diffraction (XRD), Fourier transforms infrared (FTIR) & Scanning electron microscopy (SEM). Seeds were collected from recognized sources and after surface sterilization; seeds were treated with GO nano solution with different concentrations (0, 20,40,60,80,100,120 and 140mg/l respectively). The conducted experiment found that GO in the concentration range from 40 to 80 mg/l (T2 to T4) gives positive results in the maximum of all aspects in both the annuals. The maximum root length of the marigold was recorded in T2 (5.91cm) and shoot length in T5 with 4.63cm. The coefficient of the velocity of germination (CVG) for calendula was observed maximum in T3 (32.17) and in marigold T2 (46.34). In GO treated seeds were having a dense rooting system with good seedling growth, early germination rate also observed in treated seeds in comparison to control.

This standard provides a detailed description of the phytosanitary risk analysis process performed on the lawn to determine if a pest may be a quarantine pest. The application of flour to risk assessment, as well as the harmonized processes required to select a phytosanitary risk management option, are described.

The wide range of variation of agronomic valuable traits of cotton makes it possible to form families that differ in the type of plant branching and the complex of agronomic valuable traits. The experiment studied the variability of agronomic valuable traits in families with the limiting and non-limiting type of branching having the same origin. A slight change in the indicators of the main agronomic valuable traits, depending on the growing conditions, characterizes the high adaptive ability of this L-33 line. The most significant influence of the correlation coefficients was observed based on the raw cotton weight of one boll, the fiber output and the weight of 1000 seeds.

This article is devoted to the research on the use of lime-sulfur decoction and surface-active substance (surfactant) against against the dangerous spider mites found in cotton plants. It was found that the use of cited preparations in the Bukhara-6 type of cotton plant in moderation resulted in extra harvest in the amount of 4.2 - 4.4 centner per hectare.

The purpose of this study is the development and implementation of a remote sensing system for the formation of primary accounting data based on the digitalization of the agricultural sector, automation of accounting processes, reducing the influence of the human factor, which allows for operational monitoring of the state of sown areas, planning agrotechnical measures, control of equipment working in the fields. There are on average 400-600 circuits per remote sensing operator. The proposed modern approach to the organization of agricultural production is aimed at reducing losses and costs, improving the quality and competitiveness of agricultural products and products from it in the national and international markets.
