In modern conditions of progressive environmental pollution, the need to save water and electricity, the production of fresh vitamin, environmentally friendly vegetable products on multi-tiered plants can be considered an urgent task. The article discusses the results of experiments on the development of individual elements of tomato production technology on a hydroponic multi-tiered pipe growing plant "Fitopiramida ". It was revealed that 2 foliar dressings at a dose (N: P: K 10:54:10) 2.5 g / l + Maxifol 2 g / l) - have a significant effect on the productivity and productivity of determinant tomato hybrids Flame F1 and Rosana F1, providing a yield increase in comparison with the control by 7.87 kg / m2 and 2.52 kg / m2, respectively. Testing of 24 varieties and hybrids of the determinant type made it possible to identify the 3 most early ripening varieties with a ripening period of 85-90 days. Based on the analysis of the test results, the directions of tomato selection for the conditions of low-volume technology are outlined. The main features are formulated for the determinant hybrid model for the " Fitopiramida " technology.

The results of the scientific research and pilot tests on the production technology of soft molded ceramic bricks based on siliceous opoka-like rocks are presented. A description of soft-molded brick, which is distinguished by a huge variety of appearance and unusual design, which has earned recognition from architects and designers, is given. It is emphasized that the main limiting factor for the wide distribution of this type of brick is its high cost, due to the very small volumes of its production in Russia. It is indicated that the current situation poses a very difficult and urgent task for the wall ceramics industry - to establish the widespread production of soft-molded bricks, which in addition to the aesthetic properties will have the good operational properties. The opoka-like rocks’ characteristics and the results of studying their ceramic properties in relation to the technology of soft molding are given. The classification of the soft molded brick front surface types is presented for discussion. The main technological parameters of production, the relationship and the influence of various technological factors on the properties of the products obtained, as well as the mechanism for forming the structure of the calcined products are determined. A variable technological scheme for the production of soft molded ashlar brick has been developed. It is emphasized that the presented research results will be of interest to a wide circle of the molded ceramic bricks’ manufacturers and will help to establish the wide production of soft-molded bricks in Russia.

In this paper a mathematical model for obtaining probability distribution of the knowledge testing results is proposed. Differences and similarities of this model and Item Response Theory (IRT) logistic model are discussed. Probability distributions of 10 items test results for low, middle and high ability populations selecting characteristic functions of the various difficulty items combinations are obtained. Entropy function values for these items combinations are counted. These results enable to formulate recomendations for test items selection for various testing groups according to their attainment level. Method of selection of a suitable item characteristic function based on the Kolmogorov compatibility test, is proposed. This method is illustrated by applying it to a discreet mathematics test item.

The study was conducted to evaluate the turnip variety purple top white globe for yield and yield contributing characters  through front line demonstration in District Budgam for three consecutive years 2018,2019 and 2020.A total of 25 FLD’s were distributed in village Roshanabad of block Narbal, District Budgam. The results obtained reveals that the improved variety was having higher yield and hence better returns to the farmers as compared to the local variety. Study also revealed a wide gap in the production technology of turnip. The farmers themselves observed the difference between the improved variety and local. The yield increase of 57.9% over the control and B:C ratio of 3.48 in demonstration plot (2.13 in control) may be attributed to scientific cultivation method viz proper selection of variety, use of quality seed, seed treatment, proper spacing, recommended dose of fertilizers and integrated pest management.

A large number of forms and varieties of garlic created in the selection process allowed this culture to spread almost all over the world: in temperate regions, in subtropics and even in tropical regions. Currently, the world's acreage of garlic is 1.438 million hectares, the average yield is 16.9 tons per hectare, the gross yield is 24.255 million tons. The largest producers of garlic are China, India, South Korea and Egypt. The highest yield was recorded in Uzbekistan, Egypt, China, Tadjikistan. In Uzbekistan, it is grown everywhere, mainly on household plots and small areas in farms. In the republic, varieties of garlic are South-violet (1972) and May VIR (1978). Since 2004, the Surkhandarya Scientific Experimental Station of the VegetableMelon Crops and Potato Research Institute has been conducting selection work to create new varieties of garlic. As a result of the research, the Chidamli variety was introduced and, since 2016, introduced into the State Register. All zoned varieties belong to the group of autumn-sprouting varieties. In 2011- 2015, about 100 promising clones of garlic were evaluated in the south of Uzbekistan. The effectiveness of selection for the size of bulbs and teeth is revealed. Clones with a mass of bulbs and teeth are isolated. Clones with a bulb weight of more than 80 g and a tooth mass of more than 6 g are distinguished. They are a valuable source for the creation of high-yielding varieties of garlic in Uzbekistan.

Chicken Feather

The influence of chemical treatment on the mechanical properties of treated chicken feather fibre-reinforced unsaturated polyester resin (TCFF-UPR) composites was studied in this research. Redundant portions of chicken from poultry farms are comprehensively contaminating the environment. To minimize environmental pollution, these redundant portions need to use for the production of other materials. In this study, we used chicken feather for the preparation of useful composites combining with unsaturated polyester resin (UPR) to reduce environmental pollution. The composites were prepared successfully by conventional hand lay up technique using modified chicken feather as the reinforcing phase of composites. For preparing composites different percentages (2, 5, 7, 10, 12 and 15% by weight) of fibre were used. Attained tensile test results expressed significant enhancement in the tensile properties of composites, with the optimum combination of tensile strength presented by 5 wt% , tensile modulus presented by 10 wt% untreated chicken feather bio-fibre reinforcement and bending strength by 5 wt% chicken feather bio-fibre reinforcement.

Recently, in Central Florida tomato production fields, tomato foliage and fruit were observed with symptoms similar to bacterial speck. Fluorescent pseudomonads were consistently isolated and the strains were characterized by standard LOPAT tests, pathogenicity tests, and genetic characterization using 16S ribosomal RNA (rRNA) sequences and multilocus sequence analysis (MLSA) of conserved housekeeping genes. LOPAT test results indicated that the strains were likely Pseudomonas cichorii. These strains were pathogenic on tomato and were also pathogenic on lettuce, the host for the type strain of P. cichorii. Likewise, strains of P. cichorii isolated in Florida since the early 1980s from hosts other than tomato, along with the type strain, were also pathogenic on tomato. Genetic characterization using 16S rRNA and MLSA confirmed that the strains were most closely related to P. cichorii but varied significantly from the type strain. The Florida P. cichorii strains formed a separate phylogenetic group along with P. cichorii strains isolated from tomato in Tanzania. These strains were different from the previously described morphotypes and genomovars of P. cichorii. Our results indicate the presence of a genetically distinct group of multihost pathogenic P. cichorii strains that have been present in Florida since at least the early 1980s.
