The study of different rice varieties, determination of their compatibility with soil and climatic conditions is the most important direction in the development of agricultural science. In 2022, research work was carried out on three rice varieties in the village of Shikhakaran, Lankaran district: Govhar (regional), Sarykiprik (local) and Avangard (improved). Soil samples were collected and analyzed taking into account the introduction of various organic fertilizers, including nitrogen, phosphorus and potassium in five variants and three replicates. Phenological observations were carried out and the qualitative and quantitative indicators of plants were studied. According to the results obtained, it can be noted that rice growth varies from 109.3 to 148.0 cm, plant bushing is 6.7-15.5 cm. The highest bushing was noted against the background of mineral fertilizer in the Govhar variety. The length of the lateral shoots is at least 21.5 cm, maximum 25.2 cm. Accordingly, the number of grains on the lateral shoots is 56.0-109.4 pcs. On the lateral shoots, the highest indicator was observed in the Govhar variety - 2.0-5.2 g. The productivity of the Govhar variety against the background of mineral fertilizers was 25.5 g, and for the Avangard variety - 23.3 g. The thousand seed weight is 23.2-33.1 g, and the Govhar, Sarykiprik, Avangard varieties were distinguished by relatively high indicators against the background of mineral fertilizer. In grains, in terms of protein content, against the background of organic fertilizer, the Govhar variety was 9.03%, against the background without fertilizer, the Sarykiprik variety - 9.3%, against the background of organic and mineral fertilizer, the Avangard variety - 8.87%. No differences in the amount of sugar in seeds were found between the varieties.

Paddy occupies the 2nd place among all plants in terms of cultivated area on the earth. And the world feeds two fifths of the earth’s population. The paddy plantneeds heat and high humiduty. Paddy, the most adaptable cereal crop in termsof climate, is grown in a large place and landscape types [1].

Since ancient times, the paddy has been grown in Azerbaijan. The paddy agriculture is performed in Astara, Central Aran, Mil-Mughan and Shirvan-Salyan economical regions. In terms of evolution,this plant is grown in in Lankaran-Astara zone because these zones belong to subequatorial, humid tropical, subtropical regions. The population of this region evaluate rice in comparison with the wheat that’s why the rice has consolidated its place in the region’s national kitchen over the sentures. The historical facts proved that the population of this region was actively busy with the paddy-growing. Encouraged by the state support to the agricultural sector, the residents of the district started to engage in this profitable field again. 526 hectares In 2017, 526 hectares of paddy were planted in Lankaran, 195 hectares in Masalli, and 245 hectares in Aran region-Aghdash. The farmers’ interst increases in this area mostly. It is more important to begin sowing from April to May taking into account the regions. It is advisible to plant paddy in the Lankaran-Masalli zone starting from the 1st 10 days of May, in the Shaki-Zagatala and Aghdash zone from the 3st 10 days of April. Generally, sowing can be performed, if the temperature is 120C [4, 6].

The paddy loves heat. Minimum germination temperature of the seed is 12-160C. The period from complete germination of paddy to the end of bushing is 30-32 days. Bushing happens depending on seed sort and the timely implementation of agrotechnical rules. 22-25 days are required from bushing end to flowering. Maturity and wax is formed in 18-20 days. Generally, cultivation period of the paddy ends for 115-140 days. Due to the fact that formation time of paddy worms is in the initial period of bushing after sowing, it is advisible to treat them with “Karte”.

Material and Methodology

A main aim of the research: State program for the paddy-growing in the Republic of Azerbaijan for 2018-2025” was adopted by the order approved by the President of the country Mr. Ilham Aliyev on February 9, 2018. The targets of the State Program for 2025 are to increase the total production to 10 000 hectares, the total production to 40 000 tons, and the average yield to 40 s/h. And this makes it necessary to carry out extensive scientific–researches. All these are possible at the expense of main aim of the research is to achieve development of the local and introduced paddy sorts with rational methods, increase of ecologically pure agricultural products manufacture.

Tasks of research: the following tasks have been set for achieving the goal; the research object -investigation of the morphological, agro-physical and agrochemical indicators; application of organic fertilizers according to soil need; study of the irrigated water resources content; analysis of the climate condition during the plant vegetation; realization of the sowing for the region by applying different organic fertilizers-the cow, sheep and bird manure, mineral fertilizer background and variants without fertilizer, carrying out phonological observations, studying qualitative indicators after crop harvest, performing observations.

The soil samples were taken and analyzed in order to study an amount of macro and micro elements, physical and chemical characters before and after sowing. pH size of soil acidity was calculated by measuring of organic carbon (%) with humid oxidization method, total nitrogen (%) — Kedal method, absorbing phosphorus (mg/kg) with Olsen method, Potassium (mg/kg) amount with ammonium acetate method. Composition of organic fertilizers, chemical characters of water for irrigation use was studied. The sowing material was selected and cleaned. The research was performed on Govhar, Sarikirpik and Avanqard sorts. The observations were performed, qualitative and quantitative indicators were studied in the phonological stages after sowing.

Research Object and Conduction Methods

The research was carried out in 3 repetitions and 5 variants in the 686 m2. The variants consist of bird, sheep and cow manure and non-fertilizer variant. The research was carried out on 3 paddy sorts — Govhar, Sarikirpik and Avangard. The influence of the control and different fertilizers on agronomic chacters, qualitative and quantitative indicators was analyzed.

During the experiments fulfillment, the phonological observations were performed on all the agro-technical measures, field research works and plants about cultivation of the paddy plant. During the research, the structural analyses were performed, the soil samples were taken before sowing and after crop harvest and their agro-physical and agro-chemical characters were analyzed.

Research Progress

The paddy is mainly planted by 2 methods: i.e. with hand and seedling. It has been proven in practice to carry out sowing with seedling techniques in areas with flat terrain and large waterholding patches. During manual sowing, seed loss and breakage isn’t allowed because the seeds are evenly distributed in the food plots. That is, the seed is saved. The technique is used in Lankaran. That is, the paddy is planted by the seedling method. At this time the paddy seedling is grown in the special seed-plots (tumchar) [2, 5].

The sprinkle is begun while the temperature is 10-120 C, but in the water it is 14-150 C at the end of April and at the beginning of May. The sprinkle was performed with 20x20 cm scheme by the quadratic nest method, 1 (one) plant (seedling) was planted in every nest when a length of seedling is 15-17 cm (Figure 1, 2).

The paddy plant needs the water. Watering is preferred during seedling planting. The paddy development is in 2 stages: the period from the 1st paddy germination to bushing (Figure 3, 4). At this time the high humidity should be achieved and the sowing should be buried in water, but the 2nd from bushing phase to wax maturity phase the fields must be buried in water. During the wax maturity the water is gradually cut off and moisture of the field can be dried to 70%. If there are weeds, they must be fought. Darican grass (Echinochloa spp), Giz grass ( Cyperus difformus ), weeds were observed (Figure 5, 6) and cleaned with mechanical ways. One of the factors affecting growth and development of the plants is temperature. The paddy, that is a grain plant, is very sensitive to both low (at 1⁰C temperature) and high temperature stress. If the flowers live at 35⁰C or more temperature more than 1 hour, the paddy seed can’t be formed [1, 3].

Predictions for the upcoming season help crop management that is characteristic for yield growth and assessment of the pests. The sorts which are diseases and heat resistant and prognostic models should be offered. Rice yield of paddy changes depending on sort, color, form of the seed, the transport period of rice, degree of seed breakage, glassiness, in which part of the grain is the floury part, cracking degree, growing condition, correct use of the agro-technical measures. Rice yield rises till 3% depending on fertilizer kind, dose and giving period. Application of the fertilizers increase productivity, highly affects the chemical content of paddy. An amount of albumen can be increased to 2% at the expense of nitrogen against the background of phosphorus and potassium that is given under paddy. 35-40 centners are harvested from each hectare of paddy, there is 50-60 centners and more productivity in the areas where highly agro-technical service is performed [4, 6].

We carried out researches in 3 repetitions, 5 variants on paddy plant in the Shikhakaran village of the Lankaran region in 2022 (Table 1).

3 paddy sorts — Govhar (regional), Sarikirpik (local) and Avangard (improved) sorts were studied in different fertilizer variants. So, these sorts were planted in blocks in the cow, bird and sheep manures, mineral fertilizers are applied, as well as in the non-fertilizer options, all phonological phases of the plants were also agro-technical maintenance work, observation and records were carried out. The seedlings were planted on June 4, 2022. The samples were taken from 3 plants on each variant and repetition which were in the blocs and structural analyses were performed on September 3.

The soil samples were taken on available 15 blocs and they were analyzed in the laboratory (Figure 7, 8).

Harvesting has been done since the 1st 10 days of September. The paddy seeds have been cleaned in different apparatus, sorted and packaged, stored up for next year.

As it is seen from the 1st table, a length of the paddy samples changes by 109,0-148,0 cm, a length of the most samples is more than 100,0 cm. Bushing of the plants was observed 6,7-15,5 cm depending on separate samples. According to bushing, the highest index was noted in Govhar sort against the mineral fertilizer. A length of the brooms is minimum 21,5, maximum 25,2 cm.

The number of seeds in broom is accordingly 56,0-109,4. This index was observed in Avangard sort against the background of mineral fertilizer, Govhar sort against the background of sheep fertilizer (Table 2, Figure 9).

The highest index of the seed mass on sorts and background is 2,0-5,2 grams was observed in Govhar sort. The plant productivity in Govhar (25,5 g) and Avangard (23,3) sorts was noted against the mineral background. One of the important elements of productivity is considered the plant productivity and mass of 1000 seeds. These indicators accordingly change by 17,6-28,22 g and 23,2-33,1, Govhar, Sarikirpik and Avangard sorts differed on mineral fertilizer background.

While evaluating quality of the paddy, its rice yielding, the increase in the volume of the cooked rice, disintegration and chemical composition of the cooked rice is taken as a basis. An amount of albumen in the seed was superior — Govhar was 9,03% on the background of sheep, Sarikirpik was 9,3% on the background of non-fertilizer fertilizer, Avangard sort was 8,87% on the background of cow and mineral fertilizers. The important differences weren’t according to the quantity of sucrose (Table 3, Figure 9).

Conclusion

Recently, some important measures have been realized in the direction of paddy production increase and meeting the population’s demand for rice, development of paddy-growing that is one of the traditional areas of agriculture and positive results were obtained.

In the research year, an influence of organic and mineral fertilizers on 3 paddy sorts -Avangard, Sarikirpik and Govhar sorts was studied. The changes occurring in qualitative and quantitative indicators were dynamically and comparatively analyzed, the following results were obtained:

A length of the paddy samples is 109,3-148,0 cm, but the length of the most samples is more than 100,0 cm.

Bushing of the plants was 6,7-15,5 cm depending on separate samples. The highest index according to bushing was noted in Govhar sort on the background of mineral fertilizer.

The length of brooms in plant is minimum — 21,5 cm, maximum — 25,2 cm. The number of the seeds is 56,0-109,4, this index was observed in Avangard sort on the background of mineral fertilizer, in Govhar sort on the background of the sheep manure.

The seed mass differed on sorts and backgrounds, the highest index was 2,0-5,2 grams in Govhar sort. The plant productivity was noted in Govhar (25,5) and Avangard (23,3) sorts on the background of mineral fertilizer.

The plant productivity and mass of 1000 seeds is accordingly 17,6-28,22 gand 23,2-33,1 and they differed with the highest indicators in Govhar, Sarikirpik and Avangard sorts on the background of mineral fertilizer.

Rationality of each research, achievement of its application in private and farmer farms are one of the main issues. For this purpose in Juneç July an August, in the experimented areas, regional meetings and field days were held with the direct participation of farmers, landowners, large grain farms, large entrepreneurs and specialists of agrarian training centers. Necessary information about new cultivars was given, discussions were held, effective recommendations were given.
