Sudden Decrease

Drought conditions in the western United States have limited water availability for the irrigation of agricultural products. This can have a dramatic impact on yield and quality of specialty perennial crops, such as juice grapes (Vitis labruscana Bailey). Washington State juice grape industry typically irrigates to 100% of crop-specific evapotranspiration (ETc) throughout the season to minimize yield loss. However, as conditions have limited water availability, growers need a new strategy to cope with the limited water supply. Regulated deficit irrigation (RDI) applies less water than plant ETc and has been shown to improve fruit quality in red wine grapes (Vitis vinifera). The objectives of this study were to evaluate the effects of RDI treatments on the yield and quality of ‘Concord’ juice grapes as compared with current commercial practice. The treatments reduced the amount of water applied between bloom and veraison by 25% (−25%), 33% (−33%), and 45% (−45%) from the control application. The results of this 4-year study initially indicated a dramatic decrease in yield in the −45% treatment (7.5 Mg/ha) as compared with the control treatment (19.2 Mg/ha); however, yield for the RDI treatments recovered in the subsequent seasons and was not statically different from the control. There were no statistical differences in fruit quality between treatments. This indicates that RDI has the potential to decrease water applied between bloom and veraison without impacting fruit quality; however, to avoid a sudden decrease in yield, it would be necessary to gradually reduce water applications over several years.

Soil Volume

Individual and interactive effects of restricted root volume (RRV) and regulated deficit irrigation (RDI) on vegetative growth and mineral nutrition of peach trees [Prunus persica (L.) Batsch (Peach Group) `Golden Queen'] were studied over 3 years (1992-95). Trees were grown in lysimeters of five different volumes (0.025, 0.06, 0.15, 0.4, and 1.0 m3) with either full or deficit (RDI) irrigation. Increasing soil volume increased vegetative growth as measured by trunk cross-sectional area (TCA) (linear and quadratic, P < 0.011) and tree weight (linear, P < 0.001) with the final TCA ranging from 29.0 to 51.0 cm2 and tree weight ranging from 7.2 to 12.1 kg for the smallest to largest volumes. Root density measured at the completion of the experiment decreased with increasing soil volume (linear and quadratic, P < 0.001) with root length density declining from 24.0 to 2.0 cm·cm-3. RDI reduced vegetative growth by up to 70% as measured by weight of summer prunings. Root restriction was effective in controlling vegetative vigor and is a viable alternative for control of vegetative growth. Mineral nutrition did not limit tree growth.

The Impact

In the last decade, Ural and Siberian breeders have created a series of valuable and strong varieties of spring soft wheat, which have mainly successfully passed the State Variety Testing and are included in the Register of breeding achievements in 10 regions. These include the Irene variety, which is sown not only in Western Siberia, but also in Eastern Siberia and other regions of the country. It is well adapted to the conditions of the Tyumen region. The variety has been grown here for 13 years, but the variety technology has not yet been fully developed. It is cultivated according to generally accepted technology. Taking into account the current situation with the variety, we are conducting research on the development of elements of varietal technology. The article analyzes the results of the impact of mineral nutrition levels on the yield and quality of grain of spring soft wheat variety Irene in KRiMM Uporvo district of Tyumen region. Over the years of research (2016–2018), it was established that the leached black soil in the control version without mineral fertilizers yielded 2.57 t/ha of early maturing Irene variety. The variety reacts positively to the application of mineral fertilizers up to the yield level of 5 t/ha. At the same time, the yield is combined with the quality of grain. Profitability of application of mineral fertilizers for the yield of 4 and 5 tons per hectare was 130.7 and 139.5 %, respectively. In the control version it was 61.3 %. Irene variety is well adapted to the conditions of the Tyumen region, it is necessary to continue the study of other elements of the variety.

Crop demands for irrigation require different technologies to optimize the use of water. Regulated Deficit Irrigation (RDI) is a strategy that enables a significant reduction of water application without affecting the crop yield and quality, with the advantage of being a tool for control of vegetative growth. The present study was conducted in Sesquile, Cundinamarca (Colombia) between 2015 and 2016. The objective was to evaluate the quality and development of pear crop (Pyrus communis L. cv. Triumph of Vienna) on field conditions, using three treatments of 100%, and 25% of water requirement (ETc) and no irrigation, applied at the rapid fruit growth stage. The mid day stem water potential, plant water relations, pressure-volume curve, fruit yield and quality were evaluated. There were no significant differences in the yield and quality of the fruits among the different irrigation treatments. The trees had the mechanisms of osmotic adjustment, which allowed water stressed trees to cope with irrigation restrictions during the rapid fruit growth stage without affecting the yield.

Silicon (Si) and biostimulant management have been proposed techniques to reduce the impacts of abiotic stresses and to increase the productivity of several crops, however, there are still few concise results of the management of this crop. The objective of this work was to evaluate the effects of biostimulant and silicon treatments on isolated or mixed applications on mineral nutrition, yield and fiber quality of two cotton varieties. For this, an experiment was carried out in a randomized block design in the municipality of Lu&iacute;s Eduardo Magalh&atilde;es-BA, in a 4 &times; 2 factorial arrangement, with four replications, in which four biostimulant treatments (control, without application; Si; biostimulant; and Si + biostimulant) were evaluated in two cotton varieties (FM 954GLT and FM 983GLT). The nutrient content of leaves, relative water content, electrolyte leakage, fiber yield, and quality were evaluated, the data collected were submitted to the F test and means were compared by Tukey at 5% probability. At the end of the experiment, it was verified that the management of Si and biostimulants increase the integrity of the cell wall, the association of Si + biostimulant increases the levels of N, Fe and Si foliar and reduces the levels of B and Mn, and do not influence on yield and fiber quality.

В статье приводятся результаты исследований 2018-2019 гг., проведенных в почвенно-климатических условиях Юго-западной зоны виноградарства Крыма, по оценке влияния отечественных микроудобрений на рост, хозяйственные и увологические показатели столового винограда сорта Мускат янтарный. Экспериментально доказано, что использование изучаемых систем минерального питания микроудобрениями Органомикс и Форрис при внекорневых обработках виноградной лозы позволило существенно увеличить урожайность в среднем на 9,4 % (1,7 т/га), массу грозди - на 9,5 % (13,1 г), объем прироста куста - на 8,3 % (261,9 см3), снизить «горошение ягод» в грозди на 8,6 % в сравнении с контролем. The article presents the results of studies of 2018-2019, conducted in the soil and climatic conditions of the South-Western zone of viticulture of Crimea, on the assessment of the influence of domestic micro-fertilizers on the growth, economic and uvological indicators of table grape variety ‘Muscat Yantarnyi’. It was experimentally proven that the use of the studied mineral nutrition systems with Organomix and Forris micro-fertilizers for foliar treatments of the vine allowed to increase significantly the yield by an average of 9.4% (1.7 t / ha), the weight of the bunch - by 9.5% (13.1 g), the volume of bush growth - by 8.3% (261.9 cm), to reduce the millerandage of the bunch by 8.6% in comparison with the control.
