CONVENIENT PLANTING SCHEMES OF WHITE CABBAGE IN LATE-RIPENING AND THE DENSITY OF THE SEEDLINGS

Planting schemes of “Sharqiya-2” and “Saratoni” varieties of white cabbage 70x30, 70x40 control, 70x50, 90x30, and 90x40 cm in the meadow-gray soil conditions of Uzbekistan were studied. A number of seedlings per hectare according to the planting scheme: 47.6; 35.7; 28.6; 37.0 and 27.8 thousand respectively

DIRECTIONS OF INNOVATIVE AGRICULTURAL DEVELOPMENT

This article explains the concept of “innovation”, its specific features in agriculture, groups the influencing factors in the development of innovation in this area, provides practical recommendations as well as scientific proposals to further increase innovation activity in the agricultural sector. The conclusion is made about the need for an integrated approach to the regulation of innovation in the agricultural sector and the development of a system of measures aimed at increasing the innovative activity of agriculture

INFLUENCE OF DIFFERENT RATES OF MINERAL FERTILIZERS ON THE PRODUCTIVITY OF CULTIVATION OF WHITE CABBAGE

Based on the research carried out in the Tashkent region of Uzbekistan, the following conclusions can be drawn: In order to increase the yield and use the available possibilities of white cabbage varieties, we used various doses of mineral fertilizers.1. Against the background (P 150, K 100 kg / ha .) the use of ammonium nitrate in doses of 200 and 250 kg / ha contributed to an increase in the mass of the head by 9.3-13.8%

INFLUENCE OF QUALITY TREATMENT ON SOIL MOISTURE STORAGE AND SEED GROWTH

In the article, based on the results of experimental studies, the influence of soil moisture on the germination of winter wheat seeds in cotton aisles after pre-sowing treatment was studied. Technology and technical means are proposed. contributing to the reduction of evaporation and the accumulation of moisture reserves in the soil.

EXTENSION AND HARMFULNESS OF CALIFORNIAN SHIELD IN APPLE ORCHARDS

A dangerous pest is widespread in Uzbekistan, one of which is the dangerous coccidus. These include quarantine species that are considered dangerous in the republic's horticulture, including the California scale insect. In the course of observations (Tashkent region, 2018-2019) apple varieties are imported from Europe “Renet Simirenko” 6%, “White Rosemary” 8%, winter “Yellow Parmen” 5% and North American varieties “Yellow Belfleur” 4%, “Vinesep”3%, “Janatan”4%, “Jonored”5%, “Golden Delishes”8%, “King David”7%, local varieties “Samarkand First”16%, “Tashkent Borovinkasi”15% and “Nafis”19% were damaged by the California scale.

IMPLEMENTATION OF THE WATER USE PLAN PROCEDURES, MEASURES AND WATER USE

If we look at the existing irrigation methods used today in the country, then they are divided into: ground, rainfall, underground or underground, drip and spray. Basically, they are transferred to the irrigation field in two forms: through gravity and pressure irrigation systems. Naturally, a gravity irrigation system is economically more expensive than a low pressure irrigation system. However, from a performance appraisal stand point, pressure irrigation methods are less efficient and have serious disadvantages

IRRIGATION BY GROUNDWATER AT THE EXPERIMENTAL AREA IN THE KUVINSKY DISTRICT OF THE FERGANA REGION

The article talks about the rational use of water pumped out of vertical drainage wells. The solution to the problem is determined by irrigation with water from vertical drainage wells, without dumping them into the collector-drainage network. An example of irrigation is given on the experimental plot of the Kuva region, the farm "Musazhon Ismoilov".

ECOLOGICAL SIGNIFICANCE OF PHEROMONES

This article reveals the essence of the concept of "pheromones" and their biological significance. In the article variants of their application in agriculture for struggle against insects-pests are presented. The definition of term and classification of pheromones and their types are given: feromons of insects, feromons of fish, feromons of vertebrates, feromons of humans, fermons of plants, sexual feromons, anxiety feromons, trace feromons, epidemic feromons and their functions and significance for the representative's organism and the environment as a whole

PHYTOPLANKTON DEVELOPMENT DEPENDING ON THE SEASON IN THE PONDS OF THE CLEANING FACILITIES

The article presents an ecofloristic analysis of the natural algal population of reservoirs used as biological storage ponds, sedimentation tanks. Studies have shown that phytoplankton communities in reservoirs are not constant, and the composition and quantitative indicators of algaein them vary depending on meteorological conditions. In this Chapter, we consider seasonal changes in the abundance and biomass of phytoplankton, as well as their ratios in different ponds

RECLAMATION OF IRRIGATED LANDS OF SYRDARYA REGION EFFECT OF CONDITION ON AUTUMN WHEAT GRAIN YIELD

This article focuses on improving the reclamation of irrigated lands in Syrdarya region, increasing soil fertility, efficient use of available water resources in the context of water scarcity, irrigated land in the region from 2013 to 2019, groundwater level, groundwater mineralization, drainage results of data on reconstruction, soil salinity and winter wheat grain yield over the years
