Plant protection measures in flax cultivation should provide sufficiently clean from weeds, healthy sowings, forming the crop of necessary quality level, corresponding to economic and ecological criteria of modern agrotechnologies. The work aims to find promising herbicidal and protectivestimulating agents for providing cleanness from weeds and the health of flax crops when treating them with new pesticides, contributing to increasing the yield and quality of flax products. According to the classical methodology of scientific agronomy, the main experiments were carried out in the fields of FSBSI Federal Scientific Centre for Bast Crop, Flax Research Institute in the Tver region. As a result of experiments in 2018-2020, the herbicide Shanti and its mixture with Shanstrel 300 showed relatively high biological efficacy in protecting flax against dicotyledonous weeds. Furthermore, the addition of graminicides Haloshans or Cletoshans, growth regulator Artafit or fungicide Zimoshans to anti-wort herbicides did not reduce the effectiveness of the drug mixtures on dicotyledonous weeds and eliminated cereal weeds in crops. Additionally, Artafit and Zimoshans effectively protected flax from pasmo and other diseases, naturally increasing the yield of flax products. Its maximum values in the experiment were obtained in the variant of Artafit application together with herbicides. The use of Artafit had a positive effect on the quality of flax straw, increased it by 1-2 grades (from 2.00 to 2.50).

Introduction. The processe of harvesting fiber flax is characterized by tough interactions of the work tools of the flax puller and parts of plants. Different principles and design of work tools for taking out seed bolls from the stem, used in flax harvesting machines, have both advantages and disadvantages. Single-drum comb deseeders are the most effective, but the level of damage to the stems caused during the working of these mechanisms is high. The purpose of this work is the experimental substantiation of constructive changes in the comb deseeder, which allows reducing damage to the stems of the flax fiber in the process of combing and improving the quality of the flax material. Materials and Methods. Fields and laboratories studies of flax harvesting and technological tests of flax straw and fiber were carried out according to the existing methods and standard protocols (GOST). The influence of the harvesting combine speed and deseeder type (the drum for the taking flax balls off by the stems’ combing and for the transporting removed balls to hopper) on the yield and quality of the fiber were determined. The fiber flax variety Alexim (cultivated by All Russian Research Institute for Flax Production, Torzhok) was used as a plant object and the harvesting was carried out in the vegetation stage “yellow stem” – “full ripeness”. Results. The classical design of the combing drum with four ridges for deseeding was changed to three ones that means only one of ridges should be in the layer of flax stems during the combing process. That design could decrease damage to the stems when deseeding stems. Instrumental assessment of fiber shows that after the deseeding by the threeridges drum the quality of flax straw was 0.97–1.09 numbers that was by 0.19–0.28 numbers higher than after using four-ridges drums. Conclusions. The obtained data indicate that the reducing of the load on the flax stems has a positive effect on the quality of the fibrous products. The yield of long fiber increases by 1.27–1.54% (abs.), and the fiber quality – by 0.3 numbers.

Caraway has very low competitive ability against most of weed species. Therefore, it is important to choose a suitable herbicide control, especially at biennial caraway. The experiments with the herbicides applied in caraway were found in pure growth, with variety Kepron (with standard length of ve­ge­ta­ti­ve period). The aim of the trials was to find out the differences at achenes yiled and essential oil content after the treatment by the various herbicides, applied preemergently. Also, the selective ac­ti­vi­ty of individual herbicides was tested, including the different doses. The herbicides used in the ex­pe­ri­ments had enough level of selektivity on the plants of caraway. They had a positive effect on the yiled comparing to non-treated control variant in all observed years. There was no statistically significant difference in essential oil kontent between the treated variants and non-treated control. On the basis of these results, the most suitable herbicide was chosen for the „minor“ registration for caraway.

To carry out effective plant protection measures, it is necessary to take into account all the factors affecting the quality of the crop. The aim of our research was to study the degree of development of leaf diseases of winter wheat and the rate of infestation of crops, depending on the tillage method. The studies were carried out in 2019-2020 at the experimental plots of “Kuban educational farm” in Krasnodar. For the research, four experimental plots with Steppe variety of soft winter wheat were created, where various soil cultivation systems were applied: 1 - No-Till (zero technology), 2 - moldboard-free technology, 3 - recommended, 4 - moldboard technology. The article presents data on the degree of development of diseases and the degree of infestation of winter wheat plants in the crops of test plots with various tillage systems. It was found that the most preferable is the use of the recommended type of treatment, since with it the least number of diseases develops and the degree of development of pathogens is reduced by 2-3 times in comparison with other options. The influence of the tillage method on the number and composition of phytopathogen spores was revealed.

The article considers the effect of increasing doses and various combinations of mineral fertilizers applied to the cover crop on the yield and quality of a mixture of perennial grasses of two - years use, as well as the effect of fertilizers on the agrochemical parameters of sod-podzolic light loamy soil. The objects of the study were Stodolich meadow clover and Leningradskaya 204 meadow timothy grass. The studies were carried out in two crop rotations - with standard and reduced single doses of mineral fertilizers. The research results showed that in the years (VIII rotation) when the unit dose of fertilizers was increased to N20P20K25, the yield of perennial grasses was higher compared to the harvest in the VII rotation. The most appropriate dose in the VII rotation on perennial grasses of the 1st year was N30P30K45, on grasses of the 2nd year - doses of N30P30K45 and N40P40K60. In the VIII rotation, the highest yield of perennial grasses of the 1st year of use was obtained at a dose of N160P160K200 (8.4 t / ha), of grasses of the 2nd year of use at doses of N80P80K100 and N100P100K125 (6.5 t / ha). Positive effect of increasing doses of mineral fertilizers on the content of soil organic matter has been noted. On the contrary, the soil acidity increased from 4.7 to 4.3 units with an increase of mineral doses. Higher doses of fertilizers increased the content of mobile forms of phosphorus and potassium in the soil.

A field experiment was conducted at Bangladesh Jute Research Institute (BJRI) to observe the response of N, P, K and S on a pre?released white jute (Corchorus capsularis) var. BJC?2197. The experiment was carried out by applying N, P, K, S fertilizers in ten combinations including control. From the experiment it was observed that all the treatments had significant positive effect over control on growth, yield and quality parameters. The highest fiber yield (3.21 t/ha) and stick yield (6.58 t/ha) were recorded with N90P5K30S10 kg/ha treatment. However, the best quality fiber was found with combination of N90P15K30S10 kg/ha treatment. From the economic analysis point of view, it was found that combination of N90P5K30S10 kg/ha was higher (2.30) than N90P15K30S10 kg/ha (2.04). So the former can be considered as the best combination for var. BJC?2197 in terms of BCR, yield and quality. Dhaka Univ. J. Biol.

Green gram is one of the most important kharif pulse crops of India. It is of short duration, can fit well in crop rotation and, therefore, can be grown throughout the year. Information has been accumulating concerning the role of potassium and zinc in cereal crops but very little information is available regarding the nutrition of potassium and its interaction with zinc on the yield and quality of pulses. However, Malewar, Budhewar & Jadhav (1980) and Ghildiyal, Saini & Sirohi (1975) have reported significant positive effect of zinc treatment on growth attributes in green gram. The present investigations were, therefore, planned to study individual and interaction effects of potassium and zinc on growth, dry-matter and grain yield and quality of green gram.

Producing sugar beet, as it is a demanding field crop, has contributed to the raising standard of plant production. It has an outstanding place among the plants that are cultivated in the intensive plant production system. Rentability of sugar manufacture is determined by the stability of yield and the quality (saccharose content) of sugar beet. In this way, the fundamental interest both of the producers and the processing industry is high yield and quality, year by year. The yield and the quality of the sugar beet are mainly determined by the plant production system, so we studied the effect of fertilization, irrigation and plant protection.

Biostimulants are preparations that favorably impact the growth, development, and yield of plants. The research objective was to examine the effect of the frequency of use of Kelpak, Terra Sorb Complex and Fylloton biostimulants on improving the yield and nutritional properties of beans. Been seeds (variety Oczko) were sown in the first week of May in 2015, 2016, and 2017. During the growing season, Fylloton (1%), Terra Sorb Complex (0.5%), and Kelpak (1%) biostimulants were applied by single (BBCH 12-13) and double spraying of plants (BBCH 12-13, BBCH 61). All variants of treatment with biostimulants were compared with the control. Single application of Kelpak had a positive effect on increasing the number of pods. The double application of Kelpak increased the number and yield of seeds and protein contents. Double application of Fylloton increased the number of seeds, and application of Terra Sorb Complex increased the protein content in the beans. Application of all biostimulants increased the flavonoid content. Biostimulants containing seaweed (Kelpak–Ecklonia maxima extract) or amino-acid extracts (Fylloton–Ascophyllum nodosum extract and amino acids or Terra Sorb Complex–amino acids) increased the seed yield, while improving its quality by increasing the content of protein, polyphenols, and flavonoids. It was found that the double application of Kelpak biostimulant stimulated the yield and quality of beans to a greater extent.
