Abstract A two-year field experiment was conducted to analyze the growth conditions, physical features, yield, and nitrogen use efficiency (NUE) of sugar-beet under limited irrigation conditions in northeast of China. A cultivar H003 was used as plant materials; six treatments (C1-C6) were included: C1, no nitrogen applied, rain-fed; C2, 120.00 kg nitrogen hm− 2, rain-fed; C3, no nitrogen applied, hole irrigation for seeding; C4, 120.00 kg nitrogen hm− 2, hole irrigation for seeding; C5, no nitrogen applied, hole irrigation for seeding; and C6, 120.00 kg nitrogen hm− 2, hole irrigation for seeding, and irrigation at foliage rapid growth stage. The irrigation supply was only 500 mL/plant once. Results showed C6 showed the highest chlorophyll content, dry matter accumulation, yield, etc. and had the best NUE among all the treatments. In conclusion, under the routine fertilization conditions of northeast of China, the cultivation measure of hole irrigation 500 mL/plant for seeding combined with irrigation 500 mL/plant at foliage rapid growth stage greatly improved sugar-beet yield and NUE.

Irrigation Treatments

The present study investigated the effects of irrigation and phosphorus fertilizer on dry matter accumulation and phosphorus use efficiency in sugar beet for two growing seasons during 2016 and 2017, using H003 cultivar. The experiment was comprised of four treatments including NP0K-rainfed (C1), NPK-rainfed (C2), NP0K-irrigation (C3), and NPK-irrigation (C4) using 105 kg P ha-1 compared with 0 kg P ha-1. The results showed that during the whole growth period of crop, chlorophyll contents was in the order of C4 > C3 > C2 > C1. The sugar contents were higher in irrigation treatments than rain-fed. At harvest, 105 kg P ha-1 under NPK-irrigation treatment had the highest sugar yield up to 11.59 and 10.64 t∙hm-2 in 2016 and 2017 respectively. The percent increase in yield was 20.19–27.07%, 15.79–21.62% and 14.57–14.93% than C1, C2 and C3 treatments, respectively. In C4 treatment, the dry matter accumulation in roots and leaves were 25.36 and 27.48 t∙hm-2, 9.22 and 10.67 t∙hm-2 in 2016 and 2017 respectively, with 0.39% and 5.53, 11.61 and 25.02% higher than in C2 treatment. The phosphorus accumulation in roots of C4 treatment at harvesting was 9.46 and 9.97 t∙hm-2 while phosphorus accumulation in leaves of same treatment was 3.58 and 3.80 t∙hm-2 in 2016 and 2017, respectively. In irrigation treatments, the utilization efficiency of phosphate fertilizer was 16.97 and 17.33% in 2016 and 2017, respectively, with 25.52 and 29.02% higher than corresponding rainfed treatment, indicating that irrigation could significantly improve the utilization efficiency of P fertilizer. © 2021 Friends Science Publishers

This study analyzes the dynamics of sugar beet root, crown, and leaves fresh and dry matter (FM and DM, respectively) accumulation per plant and their mass ratio at different plant densities and nitrogen fertilization. The biennial field trials were set as four different planting densities (60,000, 80,000, 100,000 and 140,000 plants ha-1) and three methods of nitrogen application in spring: control – without nitrogen fertilization (N0), presowing only (N1), and presowing with topdressing (N2). Close to the maturation, the mean DM of the whole root, crown, and leaves on September 20, 2014 amounted to 28.8, 7.3 and 4.0 t ha-1, respectively, whereas it amounted to 20.7, 4.1 and 2.3 t ha-1 in 2015, respectively. Moreover, with regard to the plant densities, the highest root DM was at 140,000 and 100,000 (31.6 t ha-1 in 2014 and 22.4 t ha-1 in 2015), compared to the wider plant densities of 80,000 and 60,000 plants ha-1 (22.4 t ha-1 in 2014 and 18.1 t ha-1 in 2015). Nitrogen fertilization positively influenced on dry matter accumulation, but it was different within the years. On September 20, 2014, a presowing fertilization (N1) increased the root DM by 17%, compared to the control, whereas in 2015 the presowing with topdressing (N2) increased the root DM by 30%. The root-to-leaves FM ratio amounted to 1:3.9 on May 30, 2014, whereas it amounted to 1:0.1 on September 20, 2014. The leaves FM was at its largest on June 20, 2015, when the root-to-leaves ratio amounted to 1:1.1, and gradually decreased to 1:0.1 on September 20, 2015.

Sugar Beets

Various approaches have been used to model the productive potential of sugar beets under the conditions of unstable moistening of the steppe zone of Russia. This paper considers the general theoretical approach to the functional description of most of the processes of plant growth and development in ontogenesis, as well as of any organism, which is determined by the conversion of bioclimatic resources into the biological mass of plants. Through mathematical modeling, the potential productivity of sugar beets in the absence of limiting factors, with optimal provision of plant life factors, was determined. The second level of modeling sugar beet productivity was performed for the conditions of unstable moistening in the steppe zone of Russia, where soil moisture is a factor limiting the productivity of the crop. To predict productivity in conditions of moisture deficiency, the study used plant organs and soil processes as a model, since they determine the availability of water and nutrients for the plant root system. Given the practical applications of the data for real production conditions, the data obtained in the first and second levels of crop productivity modeling were compared with the actual yield data obtained empirically. The maximum rates of dry matter accumulation for the conditions of the steppe zone of Russia in the absence of limiting factors was not limited to the supply of photosynthetically active radiation (PAR) and could produce up to 16 t/ha of dry matter root crops. With a moisture deficit during the beginning of row closing (from the 45th to the 75th day of the growing season), there was almost no increase in the dry matter of the plant mass, which reduced the potential productivity of sugar beets by 50%.

Final Yield

Growth response of sugar beet plants to drought stress applied at different growth stages has been investigated. Cessation of watering imposed moderate water stress and resulted in the reduction of the relative water content of young and old leaves maximally by 6%. However, water content in taproot was more drastically decreased than in the shoot. Water withholding reduced dry matter accumulation and leaf assimilatory expansion when imposed at successive growth stages, especially in the case of earlier stress application. Substantial change in distribution pattern was observed when stress affected foliar development, more than 80% of dry matter was accumulated in the taproots. Water shortage negatively influenced both taproot and sugar yield by 16–52%, depending on the stress timing in the season. Drought stress did not change the sucrose concentration but when occurred in foliar and early stage of root development, decreased the contents of important non-sugar compounds like potassium and -amino-N solutes in the final yield. Overall, data concerning the different water status in particular organs implies that a hydrodynamic equilibrium does not exist within the sugar beet plant as a response to water stress. Drought imposed on the earlier stage, most drastically influenced plant growth and final yield. When water stress occurs at the end of crop cycle, sugar beet plants had a higher ability to recovery their growth.

The Impact

Impact of presowing laser irradiation of seeds on sugar beet propertiesThe aim of the experiment was to establish the influence of biostimulation on the sugar beet seeds. The seeds came from the specialized breeding program energ'hill or were irradiated by the laser in two doses. The impact of the biostimulation was analyzed by determining the nitrate reductase activity and the nitrate, chlorophyll and carotenoids contents in leaves, as well as, the dry matter and sugar concentration in mature roots. The field experiment was established for two sugar beet cultivars. Biostimulation by irradiation and a special seed breeding program energ'hill had a positive influence on some examined parameters (particularly on nitrate reductase activity in Ruveta and in numerous cases on photosynthetic pigments in both cultivars). Regarding the dry matter accumulation and sugar concentration this impact was more favourable for Tiziana than for Ruveta cultivar.
