DYNAMICS OF RADIAL GROWTH IN NORWAY SPRUCE COENOPOPULATIONS OF ALEXIS GROVES OF LOSINY OSTROV NATIONAL PARK

Posted in 2020, AGRICULTURE, Issue № 09(99) September 2020 | 0 comments

The paper studies the variability of radial growth over five years, as well as the width of the annual ring in the old-age plantation Alekseevskaya grove on the territory of Losiny Ostrov National Park. The main regularities of its short-term and long-term variability of the radial growth, the peculiarities of the influence of meteorological parameters on the amount of growth are established. The performed research confirmed the uniqueness of the Alekseevskaya grove as a plant with a high environmental value. The collapse of a significant part of the plant because of wind is a loss, but it has allowed us to select unique wood samples that are valuable for dendrochronological analysis.

DYNAMICS OF FOREST FIRES AND THE SUPPLY OF GROUND-BASED COMBUSTIBLE MATERIALS IN THE BURABAY NATIONAL PARK FORESTS

Posted in 2020, AGRICULTURE, Issue № 09(99) September 2020 | 0 comments

Over ten years, the authors analyzed the leading indicators of forest fires statistics on the territory of Burabay National Park, as well as the amount of surface fuel in the plantings of the most dangerous on fire forest types. It was determined that during the researched period, the maximum fire danger was noted in 2010 when 79 forest fires were recorded, and their total area was 338.4 hectares. In other years, the fire situation was more capable; however, fires occurred annually. Humans caused the absolute majority of forest fires. Lightning fires amounted to 6.4% of the total. In the aboveground phytomass of very dry pine trees, needles and cones dominate, and in dry pine trees, the “other” fraction, which makes for the decayed forest floor. Therefore, very dry pine forests are characterized by running and dry by independent forest fires. Based on the obtained data, the authors developed proposals on reducing the fire danger.

QUANTITATIVE INHERITANCE LINKED TO THE GENES OF THE PERICARP COLORATION OF RICE

Posted in 2020, AGRICULTURE, Issue № 08(98) August 2020 | 0 comments

This article presents the results of the research on the inheritance of a number of attributes of the F2-hybrids of the white-grained Kuboyar rice and the black-grained Gagat rice. The study was conducted at the Agricultural research center “Donskoy” in 2018-2019. The genetic analysis of F2-hybrids revealed that pericarp coloration splitting goes according to the following trihybrid scheme: 27 black to 21 brown to 16 white. Height inheritance of the F2 occurred in the form of incomplete dominance of large character values and allelomorphic differences of three gene pairings. On the panicle length, there was superdominance of significant values and positive transgression. On the number of spikelets on a panicle, there was superdominance and interaction of three gene pairings. On the mass of a thousand grains, there was negative superdominance of the character and the digenic differences of the seed parent. On the caryopsis length, there was no dominance, and the seed parents varied in the two gene pairings. On the grain width, there was the dominance of the lesser character values, and the splitting occurred in the monohybrid form. Loci linkage of all the studied characteristics to the pericarp coloration genes was established. The samples having black pericarp coloration with the optimum plant height, panicle length, grains and the weight of a thousand grains were selected for breeding.

THE PRODUCTIVE QUALITIES OF THE PRESERVED GENE POOL GROUP OF VOLGA WHITE GUINEA FOWL IN THE CONDITIONS OF A FARM HOUSEHOLD

Posted in 2020, AGRICULTURE, Issue № 08(98) August 2020 | 0 comments

The current state of the population of the Volga white Guinea fowl’s breed after the liquidation of the gene pool for its breeding in ZAO “Mariyskoye” is estimated during the research. In this article, the authors study the productive qualities of the preserved gene pool group of Volga white Guinea fowl in the conditions of a farm household. A decrease in the main productive and reproductive qualities of Guinea fowls in comparison with the previously recorded indicators in the gene pool farm was found. The decrease affected the indicators of egg production, hatchable eggs, fertilization of eggs, their hatching capacity and a growing flock, which led to a decrease of the output of Guinea fowls per one hen of the parent flock for the productive period. This decrease is estimated 10-15%. In order to maintain at a high level all the economically important indicators of the gene pool of Guinea fowl flock, it is necessary to continue the selection process with the organization of individual and collective productivity accounting. On average, judging by the number of the preserved population of the Guinea fowls, you can get no more than 65.0 heads of day-old Guinea fowls from one hen of the parent flock during the breeding season. The obtained data provide the possibility of forming a commercial flock and its possible sales of at least 20 thousand pieces of hatchable eggs or 15 thousand birds of the growing stock.

HUMUS STATE OF DERNO-PODZOLIC SOIL DURING THE LONG-TERM EXPERIMENT IN THE REPUBLIC OF MARI EL

Posted in 2020, AGRICULTURE, Issue № 08(98) August 2020 | 0 comments

The purpose of the work is to study the effect of long-term use of fertilizers on the dynamics of humus content in the derno-podzolic middle loamy soils of the Mari El Republic and to determine the interconnection between the humus content in the soil and the average annual productivity of crop rotations. The task was performed in 2009-2019 at the stationary site during a two-factor experiment. The research has shown that in the control crop rotation (the option without applying mineral fertilizers for 24 years), there is a gradual decrease in the humus content. The content of humus in the soil of the first fruit-bearing crop rotation decreased even more intensively than in the control crop rotation. The lowest humus content for all the time of research-is 1.55 %, it was indicated in the soil of the first crop rotation in 2019 (the option without the use of mineral fertilizers). The highest content of humus in the soil was indicated in the second crop rotation, where 80 t/ha of manure was used as a potatoes’ fertilizer. If there were no fertilizers used, the humus content was always higher than when using N60P60K60. The most stable humus content was in the soil of the third crop rotation. The correlation coefficient between the average annual productivity of field crop rotations and the content of humus in the soil (the option without the use of mineral fertilizers), in the grain-grass crop rotation was 0.60 units. With the annual use of mineral fertilizers, it increased to 0.75 units. A positive interconnection between crop productivity and humus content in the soil is indicated in the first crop rotation, which cannot be said about the II and III crop rotations. In variants II and III of the fruit-bearing crop rotations, the average annual productivity of agricultural crops increases while the humus content in the soil decreases. This is due to the productivity of perennial legumes herbs, which do not depend on the content of humus in the soil.

THE EVALUATION OF THE DATA ACCURACY OF THE PINE TREE HEIGHTS ANALYSIS

Posted in 2020, AGRICULTURE, Issue № 08(98) August 2020 | 0 comments

The purpose of the work is to identify the reliability of average height indicators (experiment accuracy) of the trees in the pine stocks judging by the average values and variability of heights. The general research methodology is based on the measurement of taxational specifications of the growing stock, the main elements of which are the stocks of ordinary pine. The diameters and heights of four control trees for each level of thickness were measured in each forest taxing section. In total, 1350 trees were measured according to these morphological indicators.

According to the research results, for young pines that have a significant height difference in thickness level, it is recommended to increase the number of measured heights to 5 measured trees for each level of thickness. In other pine stock ratios, it is recommended to consider the measurement of 4 control trees for each level of thickness sufficient enough.
