Effect of Fertilization on the Accumulation Overground Mass of Spring Barley Plants

Abstract

The researches results of top spring barley growth depending on varietal characteristics and nutrition are showed. Experimental studies were conducted during 2013-2017 yrs. on the experimental field of the Mykolaiv NAU. Studies have shown that the processes of accumulation of raw aboveground mass by plants of spring barley depended on the fertilizer variant and increased intensively from the phase of plant emergence into the tube before earing. In the Aeneas variety, in the earing phase, an increase in the studied indicator was observed compared to the previous phase of plant development by 726-923 g/m 2 or by 34.8-35.9 % depending on the way of nutrition. The accumulation of raw biomass by plants of the variety Aeneas, on average over the years of research, was greater than that of plants of other studied varieties. On average, over they ears of research, in the control of raw biomass of plants variety Aeneas in the phase of plants' yield in the plant stooling has accumulated 896 g/m 2 , the earing phase-1692 g/m 2 , and phase of full grainy grain-976 g/m 2 , which is 5,4-6,4; 0,9-1,7 and 1,1-2,2 % which is more compared to the raw mass of plants of the Stalker and Aeneas varieties. The same trend was observed in other variants of the experiment. The largest amount of raw top mass of Aeneas variety was in the variant of fertilization with N30P30 and the biological preparation Escort-bio-1543-2695 g/m 2 depending on the phase of growth and development of plants. The process of accumulation of dry mass in the planting phase was slow. However, al ready from the phase of the plants' we considered in the tube a significant difference depending on the nutrition of plants and the variety at 40.

Influence of Foliar Top-Dressing on the Yield of Soybean Varieties

“…It varies for several reasons, primarily the temperature of the soil and air, the intensity and duration of lighting, the level and nature of moisturising (Vozhegova et al, 2020). The level of response depends on the specific features of the genotype, dosage, and ratio of these factors (Gamayunova & Panfilova, 2020).…”

Ефективність Позакореневого Підживлення Посівів Сої

“…Для зменшення імпорту поступово відбувалося формування масового серійного виробництва мікродобрив на підприємствах вітчизняної економіки [4,16]. За спектром дії та складом ці добрива різноманітні, оскільки містять практично всі мікроелементи [3,15]. Але, незважаючи на численну пропозицію таких агрохімікатів, масове та ефективне застосування комплексних мікродобрив у технологіях вирощування основних культур обмежене через відсутність чітких рекомендацій по нормах, способах та строках їх використання залежно від конкретних ґрунтово-кліматичних умов виробництва та планової врожайності [5,14].…”

Influence of biologics on the productivity of winter wheat varieties under irrigation conditions

“…Wheat production in Europe countries is particularly dependent on synthetic fertilizers because the use of animal manure is very limited, many of the soils are naturally low in levels of soil organic matter and there are only a few legumes present in main crop rotations that could supply symbiotically fixe nitrogen (Biel et al, 2016). Research of many foreign and domestic scientists (Ying, 2019;Hashem et al, 2019;Gamayunova and Panfilova, 2020;Panfilova et al, 2020;Müller and Behrendt, 2021;Nemea et al, 2021;Holtappels et al, 2021;Panfilova, 2021;Panfilova et al, 2021) the most effect of biologics and growth-regulating drugs on the yield and quality of agricultural crops has been proven.…”
