Seasonal Irrigation

The average salinity of Jizzakh region in the vicinity of groundwater (1.5 m) under the influence of a newly built closed bed ditch, winter wheat is irrigated 3 times during the season, the current irrigation rate is 823-933 m3 / ha. The norm of seasonal irrigation was 2586 m3 / ha, and the grain yield of winter wheat was obtained depending on the experimental areas, ie the area of the new construction (experimental variant) and the old type of irrigated area (control). At the same time, the average grain yield in the experimental field was 43.2 t / ha, and in the control field - 40.1 t / ha.

The Impact

AbstractThe paper presents analysis of the impact of irrigation dose on the winter wheat Bystra yield, which is recommended for cultivation in Poland. It is a low-growing high-yield wheat cultivar. A reel sprinkler equipped with a computer for control of parameters of its operation, which was supplied with pond water was used for irrigation. Test were carried out on five fields, where four irrigation doses were used: 15, 20, 25, 30 mm. A change of weather during research in May and June caused the need to irrigate a field four times. During research, the size of the irrigation dose was measured with rain gauges on each of the investigated fields in five measurement points. One of the fields was a control field, which was not irrigated. The investigated wheat was characterized during harvesting. Research proved that the size of the irrigation dose influences the wheat yield. The grain yield between a control field and a field with the highest irrigation dose increased by twofold. Moreover, analysis of costs incurred during sprinkling were analysed.

Growth Development

In recent years, the increase in grain yield under irrigated conditions has led to a decrease in technological quality of grain. The main reason for this is the lack of nitrogen during the grain formation in wheat on gray soils with low humus content. Under irrigated conditions, one of the most urgent tasks is to increase the grain yield of winter wheat and improve technological quality. According to the results of scientific research, today winter wheat absorbs 50-55% of nitrogen fertilizers, 20-22% of phosphorus fertilizers and 55-60% of potassium fertilizers. Some of the nitrogen fertilizers not assimilated by the plant are released into the air in the ammonia state, while some are washed into the groundwater in the nitrite and nitrate state. This situation has a negative impact on the environment. This condition is prevented when the leaf orchids are fed, as well as the rate of absorption of phosphorus by the plant increases sharply.

Growth Development

1. The effect of three factors (nitrogen level, time of nitrogen application and weed control) and their interactions on three different plant densities of winter wheat have been measured. Data concerning the growth, development and yield have been examined.2. Plant populations of 104,000, 155,000 and 281,000 per acre produced on the average of all treatments 21·3, 22·4 and 23·2 cwt. grain per acre, respectively.3. An increase in nitrogen fertilizer to the 2 cwt. sulphate of ammonia per acre level increased the grain yield of all populations. This response followed an increase in the number of tillers and an increase in the percentage of tillers producing ears. There was no significant interaction between nitrogen level and plant density. The nitrogen content of the grain increased with nitrogen level.4. Time of nitrogen application did not affect the grain yield, although it did cause considerable differences in the growth and development of the plants. There was no significant interaction betweentime of application and plant density. The late application of nitrogen produced a lower yield of straw and a higher nitrogen content in the grain.5. Weed control increased the grain yield of all plant populations, this increase following an increase in the number of ears per plant. There was a significant interaction between weed control and plant density. Weed control raised the yield of the low plant population by 3·9 cwt. per acre compared with 0·9 and 2·0 cwt. for the medium and high populations. Weed control also increased the nitrogen content of the grain.6. The only other interaction concerning grain yield which was significant was that of weed control with time of nitrogen application. Weed control increased the yield of the early and late applications but inexplicably reduced the yield of the intermediate date.7. It is concluded (a) that the experiment provided no evidence that the yield of a thin stand of winter wheat can be increased further by altering normal nitrogen fertilizer application or by altering the time of application of the fertilizer; (b) that for good results weed control is essential where the plant population is low.

Experimental Researches

The results of the field experiment on production testing and implementation of the systems and introduction the soil tillage and sowing systems of winter wheat are presented. On the results of experimental researches were stated, that the applying the direct seeding of winter wheat using the seeding machine ATD-6.35 contributed to an increase in the indicators of the density of productive stems for 7,4– 20,9 %, a decrease in the grain weight out of 1 ear for 0,11–0,27 g and the weight of 1000 grains for 2,8–4,7 g compared with the use of surface tillage and seeding with seeding machine ATD-6.35 and SZ-3.6. The highest grain yield of winter wheat was formed in the variant that mentioned a surface soil tillage and seeding with ATD-6.35 and was 5,62 t/ha, which was 0,12 and 0,16 t/ha more than the variant using the seeding machine ATD-6.35 without tillage and seeding machine SZ-3.6 on surface tillage. Analysis of winter wheat grain in the phase of full ripeness showed, that the protein and gluten contents of in samples of variants 1 and 2, where the ATD-6.35 was used were higher compared to option 3 and amounted respectively to 12,7–13,3 and 24,0–25,3 % which corresponds to the requirements of grain class 2.

The purpose of the research was the agrobiological assessment of new varieties of winter wheat depending on different methods of sowing in the South-Western part of the Central black earth region of Russia. The optimal row spacing for the studied varieties, providing the highest rates of growth, development and productivity, is determined. It was found that the maximum germination of wheat seeds – 85.8%, was in the May Jubilee variety with an ordinary method of sowing, which is 3.7% higher than these varieties-standard. A similar pattern is identified in the wide-row sowing method between rows of 30 cm germination varieties may anniversary in this variant were higher by 3.1% compared to Odessa 267. The analysis of the structure of the crop (weight of 1000 grains and grain yield) revealed a change in its structural elements under the influence of different row spacing. May Jubilee variety on the complex of the studied parameters had an advantage over the standard variety, including the yield, which was about 3.82–4.11 t/ha of grain. Thus, the new varieties May Jubilee and Belgorod 16, having the greatest adaptability to the growing conditions showed the potential of productivity most fully. The best way of sowing new varieties is a wide-row with rows of 30 cm on the options with which the increase in grain yield depending on the variety was 0.32–0.39 t/ha.
